Description

  The present invention relates to a video processing apparatus, and more particularly to a video processing apparatus that is disposed between a video signal generation source such as a camera or a tape recorder and a final output in a studio or the like and performs video switching, composition, processing effects, and the like.

The video processing device to be described in this chapter is arranged between the video signal source and the final output, and performs video switching, composition, processing effect, synchronization adjustment, correction, conversion, storage, and the like.
Video signal sources include cameras, tape recorders, disk devices, videos transmitted from remote locations, and characters and images generated by computers. Broadcasting equipment, tape recorders, etc. are the destinations for final output of video.

Since such a video processing apparatus is used for various purposes, the signal source, the final output, and the configuration of the operator usually change with each use.
For example, even if the video processing apparatus is fixedly installed in a studio, the number of cameras, the type of special effect used, and the characters generated by a computer change when the program to be produced changes.

  In addition, there are cases where such a video processing apparatus is shared by a plurality of studios. For example, at a certain point in time, a video from a camera shooting a different person in each of studio A and studio B is used as one video processing apparatus. After being input and processed, it is broadcast as one program. At another point in time, Studio A and Studio B are used for different program productions, and different contents are recorded on different tape recorders.

  Alternatively, a video processing device may be installed in the mobile relay vehicle. In this case, the number of inputs and the number of temporary recording tape recorders change depending on the change of the relay target, and it is possible to cope with various configurations such as performing relay transmission and recording to the temporary recording tape recorder at the same time. Required.

As a technique corresponding to such a flexible configuration change, for example, there is a television contribution signal generating apparatus disclosed in Japanese Patent Laid-Open No. 10-65965.
FIG. 97 is a diagram showing a schematic configuration of a conventional video processing apparatus.

  In the figure, the video processing apparatus 1 is arranged at the center. The video processing apparatus 1 includes video processing units 2, 3, 4, and 5 that are composed of a video effect unit, a character generation unit, a disk device, or a storage unit using an individual storage element. These are constituent elements of the video processing apparatus 1. The video processing apparatus 1 also has a matrix switch 6. The matrix switch 6 is a component of the video processing apparatus 1. The matrix switch 6 receives the input to the video processing device 1 and the output of each video processing unit 2, 3, 4, 5, and the input to each video processing unit 2, 3, 4, 5 and the video processing device 1. Supply the output. Video sources 7, 8, 9, and 10 are connected as inputs to the matrix switch 6. The video sources 7, 8, 9, and 10 can be cameras, tape recorders, or the like, and output the original video signal. The outputs of the matrix switch 6 are output channels 11, 12, 13, and 14, which are broadcast outputs and monitor outputs, respectively. The video processing apparatus 1 is also connected to consoles 15, 16, and 17. Each of these has operation surfaces 15a, 16a, and 17a for displaying and configuring a graphical user interface. Each console 15, 16, 17 assigns a control operation of the video processing units 2, 3, 4, 5.

  In the above prior art, in order to make it possible to easily change the configuration of the video processing device 1, a plurality of video processing units 2, 3, 4, and 5 that perform various video processing independently are stored in a casing, By connecting the input / output of the video processing units 2, 3, 4, 5 and the input / output of the device (housing) to the matrix switch 6 and controlling the matrix switch 6, each video processing unit 2, 3, 4 and 5 are connected to the input / output of the apparatus in an arbitrary correspondence, or one video processing unit output is connected to the input of another video processing unit.

Furthermore, in order to eliminate the need to manually operate the intersections of the matrix switches 6, control of the matrix switches 6 by control software is supported.
Further, the video processing units 2, 3, 4, and 5 are physically independent units, and can be connected to each other by a slot (insertion terminal / contact / connector) directly or via a transmission path provided in the housing. The switch 6 can be connected.

  Furthermore, consoles 15, 16, and 17 having freely configurable operation surfaces 15a, 16a, and 17a are provided, and the operation surfaces 15a, 16a, and 17a are assigned to video processing units or video processing unit groups to be controllable. .

  The “freely configurable operation surface” necessarily means a graphical user interface-like display / operation screen for physical switches.

In the prior art, various configurations are realized in the video processing apparatus by controlling the matrix switch.
Such a video processing apparatus is often used repeatedly for several purposes. For example, a video processing apparatus used in program A and program B is used for program A on one day, used for program B on the next day, program A on the next day, and other on the next day. It is used repeatedly for several purposes, such as program C, next day program A, and so on.

  In the prior art, it is necessary to change the state (on / off) of a plurality of intersections of the matrix switch in accordance with each application whenever the application changes. For this reason, a large number of setting operations are required because the application changes, and there is a problem in efficiency.

An object of the present invention is to provide a video processing apparatus capable of setting matrix switches quickly and efficiently when the video processing apparatus is used with the previously used internal configuration.
In the prior art, the console or the operation surface of the console is assigned to the video processing unit or the video processing unit group.

  This assignment is often determined for each use of the video processing apparatus. As described above, the video processing apparatus is often used for the same application many times. In the prior art, it is necessary to operate the console assignment every time the usage is switched, which is inefficient.

  An object of the present invention is to provide a video processing apparatus that can be set efficiently when the assignment of the console to the video processing unit is the same as the previous assignment.

  On the other hand, in the field of using the video processing apparatus, in many cases, the operation of the video processing unit is for generating an output video, and therefore one console controls the video of a specific output channel. belongs to.

In the prior art, the internal configuration of the video processing apparatus using the matrix switch and the assignment of the console to the video processing unit have no relation and are independent in control.
However, considering the convenience of operation, the console is responsible for operations related to a specific output channel, and the matrix switch settings and console assignments are independent. There was a problem. In other words, it is necessary to consider the assignment of the console so as to match the setting of the matrix switch.

An object of the present invention is to provide an image processing apparatus that facilitates assignment work of operation consoles by associating matrix switch settings with assignment of operation consoles.
Further, the functions of each video processing unit are different for each video processing unit, and therefore the types and number of input mechanisms of the console required for the control operation are different. If this is reflected, it is ideal that the console has a different size and configuration depending on the corresponding (assigned) video processing unit.

However, in the prior art, a fixed size console is assigned to each video processing unit.
In addition, even when there are many types of complicated operations related to an output channel of a video processing device, it is possible to have multiple consoles take charge of them in an appropriate way other than in units of video processing units. was difficult.

An object of the present invention is to provide an image processing apparatus that can appropriately apply an operation console according to the number of operation functions required by an operation object.
Further, in the operation of turning on / off the matrix switch intersection, it is necessary to select an appropriate intersection from the intersections of a large number of input-side lines and output-side lines and to turn it on. In the conventional video processing apparatus, the input / output of each video processing unit connected to the matrix switch and the input / output of the apparatus are grasped, and the video processing unit necessary for creating the desired output is processed. I had to devise a connection, select an appropriate intersection, and control it.

In this way, it is complicated to directly specify the intersection and operate, and it is difficult to make a correct connection.
An object of the present invention is to provide an operating environment in which the internal configuration of a target video processing apparatus can be easily realized in view of the complicated work of selecting intersections of matrix switches to be controlled.

  In addition, depending on the setting of the matrix switch intersection, the path of the configured video signal may become inappropriate. For example, the output of a line that has nothing connected to the input may be connected to the video processing unit. Alternatively, only the output of the video processing unit that requires input may be connected to the matrix switch. In addition, there may be a state of intersection that causes a problem or contradiction in the route.

The generation of such a route is due to an error in setting the intersection point. However, in the prior art, such an error has not been understood until actually operated.
This hinders quick setting of the video processing apparatus and possibly damages the video processing unit.

An object of the present invention is to assist in performing quickly the internal configuration is to provide an image processing apparatus capable of preventing damage due to erroneous setting as described above.
Further, in the video processing apparatus shown in the prior art, changing the setting of the matrix switch is a serious matter that affects all the functions of the apparatus. If the setting of the intersection of the matrix switch is accidentally changed during operation, or if something other than the device administrator changes the setting during standby before operation, the intended operation cannot be performed. It becomes a serious problem.

An object of the present invention, the internal configuration is changed independently of the intention of the administrator, the result is to provide a video processing apparatus capable of preventing that hinder the operation.
In the prior art, the state of the intersection of the matrix switches is changed by manual operation or control by control software.

However, when manually operating the intersection, it is necessary to provide a manual switch group dedicated to the matrix switch, and there is a problem that the operability is poor.
Further, in the case of control by the control software, the trouble of manipulating each intersection point is saved, but it is necessary to give an instruction to the control software when making a change, and means for that is required. That is, it is necessary to provide an input device dedicated to the control software separately from the original configuration of the video processing apparatus, and there is a drawback that the apparatus configuration becomes complicated.

An object of the present invention is to provide a video processing apparatus capable of easily operating a matrix switch without complicating the apparatus configuration.
Further, in the prior art, a free video signal path arrangement of a plurality of video processing units can be realized by a matrix switch, and the internal configuration of the video processing apparatus can be reconfigured according to the purpose.

  However, there has been no means for the operator to know what the state of the intersection of the matrix switches and the internal configuration of the video processing device based on the resulting path is at a certain point in time. There was no information other than the memory or memo of the person who set the matrix switch, and it was not possible to confirm whether the internal structure was correct.

An object of the present invention is to provide a video processing apparatus capable of obtaining information related to a path realized by a matrix switch.
In the prior art, the console for operating the video processing unit is connected to the video processing apparatus main body via a communication line and assigned to each video processing unit.

  In such a connection, it is necessary to connect the same number of communication lines as the number of operation consoles to the video processing apparatus main body, and the number of cables connected to the video processing apparatus main body is increased, which is inconvenient to install. For this reason, it has been desired to connect the video processing apparatus main body and a plurality of consoles via a network.

  However, when connected to the network, all control communication from the console to the video processing unit assigned to the video processing unit is sent from the same network to the video processing apparatus main body.

An object of the present invention is to provide a video processing apparatus that can connect a console to a network and does not interfere with communication between the console and an assigned video processing unit.
In the prior art, the operation surface of the console is assigned to the video processing unit so that the operation can be performed.

The video processing apparatus starts operation after assigning a console to the video processing unit according to the purpose of use. The console performs control communication with the assigned video processing unit.
By the way, depending on the form of use, one of the consoles may be disconnected or connected during operation. At this time, if there is an incorrect console connection, there may occur a case where control communication is erroneously performed with respect to a video processing unit that is not originally assigned. The operator operates from the console assigned first, but if there is an erroneous communication from another console during operation, the control will be confused and the operation will be hindered.

  An object of the present invention is to provide a video processing apparatus that prevents an erroneous control communication from occurring and ensures that a target video processing unit is controlled only from the correct operator console assigned first.

  In the prior art, the video processing apparatus can freely configure the built-in video processing unit. However, when a complicated system configuration is to be realized using a plurality of video processing devices, the connection between the video processing devices is handled as transmission between devices. The overall configuration (video signal path) due to the connection had to be examined separately on the desk.

In addition, the console belongs to the video processing apparatus to which the console is connected, and the control of units in another video processing apparatus has to be performed by the console belonging to each video processing apparatus.
An object of the present invention is to make it possible to easily realize a target path configuration when hierarchical path connection is performed by a matrix switch using a plurality of video processing apparatuses.

In addition, an object of the present invention is to realize free assignment of a console not limited to a specific video processing device when using a plurality of video processing devices.
In the prior art, the video processing unit is controlled by a console having a freely configurable operation surface.

  The console with graphical user interface-like input means allows easy-to-understand display, is able to dynamically change the operation surface, and is freed from physical dimension limitations, There are advantages such as cost reduction by mass-produced products. On the other hand, compared to a physical console with switches such as physical knobs, it imposes a large visual burden, cannot respond to operations, is difficult to input delicate operations, and is not suitable for quick operations. There are many disadvantages, such as being appropriate and slowing reaction time.

  In the prior art, the role of the video processing unit changes depending on the route setting by the matrix switch. The input to the video processing unit changes according to the route setting and is not fixed. When a physical console was simply connected, I did not know what path the switch, such as the physical knob, would act on. For this reason, the physical console cannot be connected and used as it is.

  An object of the present invention is to enable use of a physical console having many advantages in operability in a reconfigurable video processing apparatus.

  According to the present invention, one or more video processing units, one or more video input channels, one or more video output channels, and the output of the video processing unit and the video input channel are connected to the input side. A storage means for storing the states of all or a part of the intersections of the matrix switches in a video processing apparatus comprising a matrix switch connected to the input of the video processing unit and the video output channel on the output side; And a reproducing means for setting an intersection of the matrix switches in accordance with the contents of the storage means.

  With the above configuration, when the current setting of the matrix switch is used later, the current setting is stored in the storage means. If the user wants to use the stored setting again after using it with a different setting, the reproducing means is operated.

As a result, the operator does not need to repeat the operation of setting each intersection point, and the desired setting can be made only by operating the reproduction means.
Further, by providing a plurality of sets of storage in the storage means, even when used repeatedly a plurality of settings can be set to a desired setting by simply selection specified stored in reproducer.

  In addition, according to the present invention, an external storage device using a removable and replaceable storage medium is provided, and an identifier such as a character string or a number is given to the content of the storage means and recorded in the external storage device.

  With this configuration, when it is desired to save the internal configuration of the video processing device, the matrix switch settings are recorded as a file in the external storage device. If you want to use the recorded settings, specify the file name (identifier), read it from the external storage device, and reproduce the settings.

Since an inexpensive non-volatile medium can be used for the external storage device, the setting can be reproduced by reading from the external storage device even after the video processing device is turned off.
Even when the video processing apparatus itself is replaced due to repair or the like, if the medium on which the setting is recorded is used for the replaced video processing apparatus, it can be used with the same setting as before the replacement.

As an identifier to be given to the memory, a name convenient for organization can be used, and a record of a large number of settings can be organized and saved.
Further, according to the present invention, one or more consoles for operating the video processing unit, assignment management means for assigning each of the consoles to one or more video processing units, and assignment storage means for storing the assignments And so on.

The assignment management means assigns the console to the video processing unit, stores the assignment in the assignment storage means, and reproduces the contents of the assignment storage means.
Each video processing unit is operated by a console, but the correspondence is not fixed, and can be arbitrarily changed by the assignment management means. When storing and reproducing the matrix switch settings, the assignment of the operator console is also stored at the same time, so that labor for the assignment of the operator console can be saved. Further, when changing the assignment of the console depending on the number of operators, it is possible to adapt to the situation only by reproducing the contents of the assignment storage means.

  Further, according to the present invention, one or more consoles for operating the video processing unit, specific output related unit identifying means for identifying the video processing unit arranged on the route to each output channel, Operation handling means for associating each console with an output channel is provided.

  The operation handling means receives an input for designating a set of a console and an output channel to be associated. The operator wishes to control all video processing units that affect the corresponding output channel by means of the console.

  Since the specific output related unit identifying means can identify the video processing unit on the route to a certain output channel, the operation corresponding means assigns the console to the video processing unit using this.

  The specific output related unit obtains the state (setting) of all the intersections of the matrix switch, thereby creating the information of all the routes, tracing the route to the specific output channel, and the video processing unit on the route Everything can be identified.

As a result, the designated console is assigned to the video processing unit on the route to the designated output channel.
Further, according to the present invention, the correspondence storage means for storing the correspondence between the console and the output channel by the operation correspondence means is provided.

When the output channel and the console are associated with each other, if there is a possibility that they will be used again later in the correspondence, the correspondence is stored in the correspondence storage means.
After using the video processing apparatus as a configuration for another application, if it is desired to use the original output channel and the console again, the correspondence is read from the correspondence storage means and the operation correspondence means is operated.

Further, by providing the correspondence storage means with a plurality of sets of memories, even when a plurality of associations are repeatedly used, a desired association can be achieved by simply selecting and specifying the storage.
According to the present invention, the operation handling means associates a plurality of consoles with output channels, and the operation handling means assigns each of the video processing units on the path to the designated output channel to the designated plurality of consoles. I was assigned to one of these.

  The operation handling means receives an input for designating a set of a plurality of consoles to be associated and an output channel. The operator desires to control all the video processing units that affect the corresponding output channels by operating a combination of the consoles.

  After the video processing units on the route to the designated output channel are specified, they are assigned to any one of the designated consoles. The operation handling means receives an input instructing which of the specified video processing units is assigned to which of the designated consoles.

As a result, control related to one route is divided and performed by a plurality of consoles.
In addition, according to the present invention, one or more consoles for operating the video processing unit, assignment management means for assigning each of the consoles to functions of the one or more video processing units, and an assignment for storing the assignments A storage means is provided.

  One or more video processing units in the video processing apparatus are configured to be controlled by being divided into two or more according to their functions. The video processing unit is handled as an independent unit depending on the physical and electrical configuration, but it may be appropriate to control the function in units of functions. Even a video processing unit that is regarded as a single unit may be divided and controlled by its function.

For such a video processing unit, each function is regarded as one unit, and the assignment management means assigns a console.
The assignment storage means stores assignments to the console and functions so that the assignment management means can be reproduced later.

  Further, according to the present invention, the connection storage means for storing and holding the object connected to each input and output of the matrix switch and the matrix control console for controlling the matrix switch are provided.

Each video processing unit has a unique name or number. Also, the input and output of the video processing unit can be uniquely specified by their numbers.
Each input channel and output channel of the video processing device has a unique name or number.

  The connection storage means stores the objects connected to the matrix switch by their names. The matrix switch control console displays this memory by referring to it and receives an operation input for the displayed name or the like. The corresponding intersection of the matrix switch is controlled from the received operation.

  Further, according to the present invention, the connection storage means for storing and holding the object connected to each input and output of the matrix switch, and the control path check for the operation for controlling the matrix switch and warning are performed. And an inspection means that emits.

  The matrix switch connects each input and output with an arbitrary setting of the matrix. Each output is connected to any one of the inputs. By setting the matrix switch, a route inside the video processing apparatus is created and a functional configuration is created.

  Not all combinations of matrix switch settings will result in a functional configuration that works correctly, and in some cases there may be settings that do not work, or even settings that cause the device to fail. For example, if a video processing unit with one input and one output is connected to its input by a matrix switch, it becomes a complete feedback loop, has no function to the outside world, and can possibly destroy the unit. Such a setting can occur due to an incorrect control operation.

  In this configuration, the control operation is not immediately executed, and whether or not there is a problem is checked by an inspection unit before the execution. Only when there is no problem, the setting operation is performed as it is. Alert if there is a problem. The inspection refers to the connection storage means, acquires the object connected to each input / output of the matrix switch, determines the path constituted as a result of the control, and performs the inspection.

  In addition, according to the present invention, the video processing unit can be removed and replaced, and the type of the video processing unit connected to each input and output of the matrix switch is not fixed. The inspection means, at the time of its operation, identifies the video processing unit connected to each input and output of the matrix switch, and uses the information to determine the path resulting from the control of the matrix switch. I do.

  In addition, according to the present invention, a matrix control console for controlling the matrix switch and a lock are provided, and a person having the authority to operate the matrix switch holds and manages a key suitable for the lock.

  Only when the lock is unlocked with a matching key, the matrix control console can be operated. A person who does not have a key cannot operate. In addition, when the lock is not unlocked, the matrix switch setting is not changed by mistake.

Further, according to the present invention, the matrix control console for controlling the matrix switch and the password input means are provided.
The matrix control console can be operated only when the correct password is entered in the password input means. After the operation is completed, the operation is disabled by returning to a state waiting for the password input.

  In addition, according to the present invention, one or more consoles for operating the video processing unit and an allocation management means for assigning each of the consoles to one or more video processing units are provided, and one of the consoles is provided. A mechanism for controlling and operating the matrix switch, that is, a matrix control console equivalent mechanism is provided.

A console provided with a mechanism for controlling the matrix switch can control the matrix switch in addition to the operation of the video processing unit.
Further, according to the present invention, information related to the current setting (intersection state) of the matrix switch is displayed on the console, or information related to the route created by the matrix switch is displayed.

The console is connected to the matrix switch directly or indirectly by a communication path. Send the matrix switch setting to the console and display it on the console.
Alternatively, the console displays route information. A path in which video processing units are arranged is configured by the matrix switch. The information is transmitted to the console and displayed on the console.

  The path information generation means reads the matrix switch settings and generates information on the input channels and video processing units related to the respective output channels. The information is sent to the information video output means. The information video output means generates a character or symbol video and outputs it to an output channel corresponding to the original information.

  The output to the output channel is either completely replaced with the normal output or superimposed on the normal output (performed as an overlay). This operation is not always performed, but is performed as necessary.

  In addition, according to the present invention, information transmission means for transmitting information on the current setting (intersection state) of the matrix switch, or information on the resulting path, a communication path, and display means for displaying information It was made to provide.

  The display means is connected to the information transmission means via the communication path. The information transmitted by the information transmitting means is sent to a display means at a remote location via a communication path and displayed there. A plurality of display means may be provided at different locations and connected via a communication path. Further, different contents for each display means can be received from the information transmission means and displayed.

  In addition, according to the present invention, a plurality of consoles and a housing that holds the video processing unit are connected via a network, and the video processing unit is controlled from the console via the network.

  Each console is given a unique network identifier. The console gives its network identifier to the control transmission to the video processing unit. The control transmission is received once by the allocation management means. Then, it is passed to the target video processing unit by the network identifier.

  In addition, according to the present invention, a plurality of consoles and a housing that holds the video processing unit are connected via a network, and the video processing unit is controlled from the console via the network.

Each video processing unit is assigned a unique identifier.
Each console receives and stores the notification of the identifier of the video processing unit assigned from the assignment management means before the start of the control operation.

After that, when the operator operates from the console, the console performs control transmission with the previously notified identifier, and the destination video processing unit is specified by the identifier.
The video processing unit and the casing that holds the video processing unit do not have to be integrated, and may be physically divided into a plurality of units and connected via a network. The position on the network can be specified by the assigned identifier.

The control console's own network identifier is assigned to the control transmission from the console in preparation for the need for a reply or retransmission due to a problem on the network.
Further, according to the present invention, a plurality of operation consoles and an allocation management means for assigning each of the operation consoles to one or more video processing units are provided.

Each console is given a unique identifier. Each video processing unit is given a unique identifier.
Prior to the start of the control operation, the assignment management means notifies the identifier of the video processing unit assigned to each of the consoles. The console stores the received identifier.

  When the operator operates from the console, the console gives control identifiers with the previously notified identifier and its own identifier. The control transmission is received once by the assignment management means, and the assignment management means checks the assigned video processing unit identifier and the console identifier. Only when the combination is the first assigned, the control transmission is passed to the target video processing unit. As a result, control from an operator console other than the assigned operator console becomes impossible.

  In addition, according to the present invention, in a video processing system including a plurality of video processing devices, one control console can control communication with matrix switches of all video processing devices.

  An inter-device connection storage means is provided for transferring a video from the video processing device to the video processing device and storing a connection between the video processing devices in a system that enables more complicated processing than a single video processing device. A matrix control console and a common control communication path are provided, and matrix switches of all video processing devices can be controlled from the matrix control console via the common control communication path. The matrix control console refers to the storage of the inter-device connection storage means, and provides a control operation function based on the overall video path by the control of each matrix switch.

Multiple matrix control consoles can be prepared and all can be configured to have the same function.
Further, according to the present invention, in the video processing system including a plurality of video processing devices, the console is not limited to a specific video processing device, and the video processing units and control communication of all the video processing devices are controlled. A configuration that can be used.

  The console includes a common control communication path, and the console enables control communication with the video processing units of all the video processing apparatuses via the common control communication path. The console receives designation of which video processing unit of which video processing device is assigned, and performs control communication with the assigned video processing unit.

  Further, according to the present invention, there are a plurality of input units as video processing units in the video processing apparatus, and unit input information for transferring information of a physical switch console for that purpose and an input video source of the plurality of input units. And generating means.

  The unit input information generating means generates the information of the original video source according to the setting of the matrix switch for the input of a plurality of input units that can be changed by changing the setting of the matrix switch. The original video source may be an input channel of the video processing device or an output of another video processing unit. Generate information that identifies it. Then transfer to the physical switch console.

  The physical switch console has a selection switch corresponding to input channels of a plurality of input units to be operated. Also, it has a function of displaying information received from the unit input information generating means. As a result, the meaning of the selection switch is changed by changing the setting of the matrix switch, but the meaning is provided to the operator by the display function.

  The physical switch console is not limited to the operation of a specific plurality of input units. When there are a plurality of input units, they can be assigned to one or more of them and used for the operation.

In the present invention, the setting state of the intersection point of the matrix switch is stored and reproducible. As a result, the operator does not need to repeat the operation of setting each intersection point, and a plurality of intersection points can be brought into a desired state only by reproducing the stored setting.

Also, by providing a plurality of sets of memories in the storage means, even when a plurality of settings are used repeatedly, a desired setting can be obtained by simply specifying the storage to the reproduction means.
Further, it is possible to store and reproduce settings for only some intersections, and it is possible to make a state in which only some intersections have been previously stored without changing the settings of other intersections.

If a non-volatile memory or a hard disk device is used as the storage means, the stored settings can be reproduced even when the device is turned off and then energized and operated again.
In addition, according to the present invention, the contents of the setting means are configured as a file. Thereby, the setting can be stored in an inexpensive non-volatile medium, and the setting can be reproduced even after the power is turned off.

Even when the video processing apparatus itself is replaced due to repair or the like, if the medium on which the setting is recorded is used for the replaced video processing apparatus, it can be used with the same setting as before the replacement.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A plurality of embodiments will be described. First, a common basic configuration of video processing apparatuses handled in the following embodiments will be described.

FIG. 1 is a diagram showing a first basic configuration of a video processing apparatus.
According to the first basic configuration, the video processing apparatus has the main casing 101 and stores the components of the video processing apparatus therein.

  As components, video processing units (hereinafter simply referred to as “units”) 102 to 105 are provided, and each unit 102 to 105 has an input and an output of video. There may be more than one unit input and output. Alternatively, an apparatus that performs reproduction from a replaceable disc can be used as a unit, and an output-only unit can be provided. For the sake of convenience, the inputs of each unit are indicated by numbers such as input 1 and input 2, and the outputs are also output 1 and output 2 in the same manner. Depending on the function of the unit, there are types such as a video effect unit, a character generation unit, a disk device, or a storage unit using a solid-state storage element.

  A matrix switch 106 is connected to video input and output of each unit 102 to 105. Matrix switch 106 can select any one of a plurality of inputs for each output.

  The matrix switch 106 is connected to input channels 107 to 110 and output channels 111 to 114. The input channels 107 to 110 are sequentially numbered and named as input channel 1, input channel 2,. The output channels 111 to 114 are named output channel 1, output channel 2,.

  The video processing apparatus also includes a unit operation unit 115. The unit operation unit 115 receives an operation input from the operator for the unit 102 and the like. Note that, depending on the following embodiment, there is a configuration in which a unit operation function is provided in a casing (operation console) independent from the main casing 101 so that the unit operation unit 115 is not required.

  The video processing apparatus further includes a matrix operation unit 116. The matrix operation unit 116 receives an operation input to the matrix switch 106. Depending on the following embodiment, there may be a configuration in which a matrix switch operation function is provided in a case (matrix control console) independent from the main case 101 and the matrix operation unit 116 is not required.

Although the number of units, input channels, and output channels is four in FIG. 1, the number of units, input channels, and output channels is not limited to this, and the numbers of inputs and outputs need not be the same.
FIG. 2 is a diagram showing a second basic configuration of the video processing apparatus.

  In FIG. 2, the same components as those shown in FIG. In the second basic configuration, the main housing 120 stores the matrix switch 106 and the matrix operation unit 116. The units 122, 123, 124, and 125 are physically outside the main housing 120 and are stored in the rack 121. The unit operation unit 126 receives an operation input from the operator for the unit 122. The unit operation unit 126 is provided corresponding to each unit as necessary.

  Thus, in the configuration of FIG. 2, unlike the configuration of FIG. 1, each unit 122, 123, 124, 125 is physically independent from the housing of the matrix switch 106. 2 shows an example in which the units 122, 123, 124, and 125 are stored in the rack 121, the present invention is not limited to this. As long as the units 122, 123, 124, and 125 are electrically connected to the matrix switch 106 in the same manner as in FIG. 1, the control configuration and the control method characterized by the present invention are applied. Is possible. Any physical arrangement is acceptable as long as this condition is met.

FIG. 3 is a diagram for explaining the matrix switch.
The matrix switch 106 has 10 inputs from s0 to s9 as video signal inputs and 10 outputs from d0 to d9 as video signal outputs. A cross point switch is indicated by a cross in the figure. The switch at the intersection operates so as to select only one video input signal for each video signal output, that is, to select and turn on the intersection. Thus, an arbitrary video input signal can be supplied to each video signal output.

  FIGS. 4A and 4B are diagrams showing examples of video paths configured by matrix switch settings. FIG. 4A shows a first path example, and FIG. 4B shows a second path example. A connection indicated by a broken line in the figure is a connection realized by the matrix switch 106.

  According to the first path example related to the output channel 111 shown in (A), the input channels 107 and 108 are input to the unit 102, and the output of the unit 102 is connected to the output channel 111. Yes. In this case, the matrix switch 106 selects the input s0 as the output d4, selects s1 as d5, and selects s4 as d0.

  In the second route example related to the output channel 111 shown in (B), the input channels 107 and 108 are input to the unit 104, the output of the unit 104 and the input channel 109 are input to the unit 102, and the output of the unit 102 is output. Is connected to the output channel 111. In this case, the matrix switch 106 selects the input s0 for the output d7, selects s1 for d8, selects s6 for d4, selects s2 for d5, and selects s4 for d0.

In this way, by changing the setting of the matrix switch intersection, the video path can be changed, and the units and input channels that affect the output channel can be freely changed.
This setting is possible quickly and easily without the need for cable connection or the like. It is also possible to connect the output of one unit as the input of another unit. In some cases, the output of a unit can be operated by connecting it to one of its own inputs, and such a connection is also feasible.

  Next, each embodiment corresponding to each claim will be described. In the embodiment described below, the basic configuration of the video processing apparatus described above is applied as it is or after changing a part thereof, but the description of the parts that are not changed will be omitted. Descriptions are omitted except for those components that are clearly stated to be removed or replaced.

  The video processing apparatus having the second basic configuration includes a matrix control console 140 outside the main housing 101, and the matrix control console 140 includes a storage unit 141 and a reproduction unit 142.

In the configuration of FIG. 6, the matrix operation unit 130 shown in FIG. 5 is not provided, and the matrix control console 140 performs the same function.
The matrix control console 140 is configured around a microcomputer device as in the matrix operation unit 130 of FIG. However, the matrix control console 140 of FIG. 6 uses a casing independent of the main casing 101, is connected to the main casing 101 via a communication path, and can be operated at a remote location.

Hereinafter, the operation of the present embodiment will be described with reference to the configuration of FIG.

FIG. 7 is a flowchart showing processing for storing the state of the matrix switch 106 in the storage means 131.
In step S1, an operation input instructing storage is received from the operator. In step S2, the state of the intersection is read from the matrix switch 106. In step S3, the read state of the intersection is written into the storage means 131.

FIG. 8 is a flowchart showing processing for reproducing settings from the storage unit 131.
In the reproduction unit 132, in step S11, an input for instructing setting reproduction is received from the operator. In step S12, the state of the intersection stored from the storage unit 131 is read. In step S13, the intersection point of the matrix switch 106 is set according to the read contents.

  In the processing shown in FIGS. 7 and 8, the case where one set of the settings of the entire matrix switch 106 is stored in the storage unit 131 is shown. However, as shown below, the storage unit 131 can store a plurality of sets of settings.

FIG. 9 is a flowchart showing another process for storing the state of the matrix switch 106 in the storage means 131.
In this processing, it is possible to specify a target to be stored, and a plurality of settings are stored in the storage unit 131 as index values.

  In step S21, the operator receives one or more designations of output buses (lines) to be stored and an input of a storage number, and receives an operation input for storage execution. The designation of the output bus designates one of the outputs d0 to d9 of the matrix switch 106 in FIG. The memory number is used as an index for identifying a plurality of sets of memories.

  In step S22, the state of the intersection is read from the matrix switch 106. In step S23, the setting of the read intersection is stored in the storage unit 131 using the storage number as an index.

FIG. 10 is a diagram showing a storage example of the storage means 131 corresponding to the processing of FIG. 8, wherein (A) shows a set of storage examples, and (B) shows a state of storing a plurality of sets.
First, in the set of storage examples shown in FIG. 10A, settings related to all output buses are stored in a table format. Corresponding to the name of each output bus, the name of the input connected to it is shown. Note that the correspondence of “d9” is written as “none” indicates that no input is selected. In this case, no video signal is output at d9. Alternatively, a device default signal may be output by the matrix switch 106.

If only settings related to some output buses are stored, the other rows in the table are left blank and no data is written.
Next, when a plurality of sets are stored, the setting storage is stored in the storage unit 131 as an array as shown in FIG. 10B. When accessing each set, one of the entities is selected by the index value.

  Here, the storage method as an array is shown, but as other plural sets of storage methods, various known data management methods such as management by a linear list using pointers can be applied.

FIG. 11 is a flowchart showing a process for reproducing settings from the storage unit 131.
The flowchart in FIG. 11 shows a process in which the reproduction unit 132 reproduces the setting from the storage unit 131 corresponding to the storage process in FIG.

  In step S31, an input of a storage number is received from the operator, and an operation input instruction for setting reproduction is received. In step S32, the storage number is read from the storage means 131 as an index. In step S33, the matrix switch 106 is set according to the read contents.

  If the read content is as shown in FIG. 10A, an intersection is set so that the input s4 is connected to the output d0, and an intersection is set so that s5 is connected to d1. Set the same, and so on.

According to the first embodiment described above, the setting of the matrix switch once set can be stored in the storage means, and the setting can be reproduced when used later.
As a result, the operator does not need to repeat the operation of setting each intersection, and the plurality of intersections can be brought into a desired state only by reproducing the stored setting.

Also, by providing a plurality of sets of memories in the storage means, even when a plurality of settings are used repeatedly, a desired setting can be obtained by simply specifying the storage to the reproduction means.
Further, it is possible to store and reproduce settings for only some intersections, and it is possible to make a state in which some intersections have been previously stored without changing the settings of other intersections.

If a non-volatile memory or a hard disk device is used as the storage means, the stored settings can be reproduced even when the device is turned off and then energized again.

FIG. 19 is a flowchart of another process for storing the state of the matrix switch 106 in the external storage device 153.
In the processing of FIG. 19, data is read from the storage unit 151 and written to a file in the external storage device 153, but the file name is automatically generated, eliminating the need for the operator to input the file name.

  In step S81, an input of the storage number of the storage unit 151 is received from the operator, and an instruction to write an automatic number file is received. In step S82, the contents of the storage means 151 are read using the storage number as an index. In step S83, the value of the prepared non-volatile counter variable C is converted into a character string with a decimal value, and this is used as the file name. In step S84, a file is created in the external storage device 153 with the file name, and the content read in step S82 is written. In step S85, 1 is added to the counter variable C in preparation for the next operation.

The file name created in step S83 is preferably displayed to the operator simultaneously with the save operation.
According to this embodiment, when it is desired to use the setting recorded in the external storage device 153, the file name (identifier) can be designated and read from the external storage device 153 to reproduce the setting.

  According to the second embodiment described above, an inexpensive non-volatile medium can be used for the external storage device 153. Therefore, even after the video processing device is turned off, the setting is reproduced by reading from the external storage device 153. it can.

Even when the video processing apparatus itself is replaced due to repair or the like, if the medium on which the setting is recorded is used for the replaced video processing apparatus, it can be used with the same setting as before the replacement.
As an identifier to be given to the memory, a name convenient for organization can be used, and a record of a large number of settings can be organized and saved.
<Third Embodiment>
FIG. 20 is a diagram showing the characteristic part of the third embodiment.

  The video processing apparatus according to the third embodiment includes a plurality of consoles 171a, 171b, and 171c outside the main housing 101, and includes an allocation management unit 172 and an allocation storage unit 173.

The consoles 171a, 171b, and 171c provide a function of operating the units 102, 103, 104, and 105 in the video processing apparatus.
The allocation management means 172 incorporates a microcomputer device having a CPU, RAM, ROM, and input means, and performs various operations according to programs built in the ROM.

  The assignment management means 172 assigns the consoles 171a, 171b, and 171c to units, stores the assignments in the assignment storage means 173, and reproduces the storage contents of the assignment storage means 173.

FIG. 21 is a diagram showing a storage example of the assignment storage means 173.
According to the storage example shown in FIG. 21, the unit 102 (unit 1) is operated by the operation console 171a (operation console A), and the unit 103 (unit 2) is operated by the operation console 171a (operation console A) and the unit 104 (unit 3). ) Indicates the storage of assignments operated by the console 171b (operation console B), and the unit 105 (unit 4) is operated by the console 171c (operation console C).

The console assigned to each unit is not limited to one, and there may be a plurality of consoles. In other words, the same unit may be operated from a plurality of consoles.
FIG. 22 is a diagram showing another example of storage in the assignment storage unit 173.

  According to this example, an example in which a plurality of consoles are assigned to the same unit is shown. That is, in the example shown in FIG. 22, the unit 102 (unit 1) is the console 171a (operation console A) and the operation console 171b (operation console B), and the unit 103 (unit 2) is the operation console 171a (operation console A). Operation console 171b (operation console B), unit 104 (unit 3) indicates operation storage by operation console 171b (operation console B), and unit 105 (unit 4) indicates storage of assignments operated by operation console 171c (operation console C). Yes.

An example of realization of allocation and switching by the allocation management means 172 is shown in FIG.
FIG. 23 is a diagram showing the principle of the switching mechanism of the allocation management means 172 using a matrix.

  As shown in FIG. 23, the matrix switch connects the communication path to each console and the communication path to each unit, and the communication path between each unit and the assigned console is connected. Set the intersection so that

In the illustrated example, the communication path is represented by a single line, but it is needless to say that the communication path is physically realized by a number of lines necessary for communication and intersections (switches) therefor.
FIG. 24 is a flowchart of the assignment operation of the assignment management means 172 using a matrix.

In the initial state, it is assumed that all intersections are initialized to an off state.
In step S91, the operator receives an input for instructing assignment to the console unit. In step S92, the corresponding intersection of the matrix mechanism is set. In step S93, it is determined whether there is still an assignment input. If there is a next input, the process returns to step S91.

  As another example of realizing the assignment by the assignment management means 172 and its switching, communication exchange by software will be described with reference to FIGS. 25 and 26. FIG. The assignment management means 172 incorporates a transfer table in the assignment storage means 173 for exchange. The transfer table has the same contents as the table shown in FIG. 21, for example. The assignment management unit 172 operates while referring to the transfer table.

FIG. 25 is a flowchart for processing transmission from the unit to the console.
In step S101, the unit number received from the unit side is set to N. In step S102, the console corresponding to the unit number N is acquired by referring to the built-in transfer table. In step S103, the communication received in step S101 is transferred to the corresponding console. If there are multiple corresponding consoles, transfer them to all of them.

FIG. 26 is a flowchart for processing transmission from the console to the unit.
In step S111, S is received from the console and the transmission source console is set to S. In step S112, the built-in transfer table is referred to obtain a unit number corresponding to the console identifier S. In step S113, the communication received in step S111 is transferred to the corresponding unit. If there are multiple corresponding units, transfer to all of them.

  Here, when a control instruction (command) is transmitted to a plurality of units at the same time, the unit that does not correspond to the contents ignores it. Therefore, control instructions (commands) sent simultaneously to a plurality of units having completely different functions are processed only by units having the corresponding functions.

FIG. 27 is a flowchart of the operation for determining the assignment by the transfer table.
In the initial state, the operation table column of the transfer table is initialized to a blank column.
In step S121, an input for instructing assignment to the console unit is received from the operator. In step S122, the identifier of the designated console is entered in the row of the designated unit of the transfer table. In step S123, it is determined whether there is still an assignment input. If there is a next input, the process returns to step S121.

  FIG. 28 is a flowchart showing the operation in which the assignment management means 172 stores the assignment of the console. Hereinafter, it is assumed that the assignment storage unit 173 stores a plurality of sets of assignments according to an array.

  In step S131, an input of a storage number is received from the operator, and an instruction to store the assignment is received. In step S132, the switching mechanism of the allocation management means 172, that is, the intersection mechanism in the case of using a matrix switch, and the current allocation are read out from the transfer table in the case of replacement by software. In step S133, the contents read in step S132 are written in the allocation storage means 173 using the storage number as an index.

FIG. 29 is a flowchart showing the operation of the assignment management means 172 reproducing the assignment of the console.
In step S141, an input of a storage number is received from the operator, and an instruction for reproducing the assignment is received. In step S142, the allocation is read from the allocation storage unit 173 using the storage number as an index. In step S143, the switching mechanism (matrix switch or transfer table) of the assignment management means 172 is set according to the content read in step S142.

FIG. 30 is a diagram for explaining storage and reproduction of assignments.
The assignment storage unit 173 stores a plurality of sets of assignments as an array and is accessible by an index. The allocation management unit 172 accesses the allocation storage unit 173 by the index and executes storage or reproduction.

According to the third embodiment described above, the correspondence between each unit and the console is not fixed, but can be arbitrarily changed by the assignment management unit 172. In the operation site of the video processing apparatus, when the setting of the matrix switch 106 is stored and reproduced, the assignment of the operator console is also stored and reproduced at the same time, so that labor for the assignment of the operator console can be saved. In addition, when changing the assignment of the console depending on the number of operators, it is possible to quickly adapt to the situation simply by reproducing the contents of the assignment storage means stored in advance.
<Fourth embodiment>
FIG. 31 is a diagram showing a characteristic part of the fourth embodiment.

  The video processing apparatus according to the fourth embodiment includes a plurality of consoles 181a, 181b, and 181c outside the main casing 101, and a specific output related unit identifying unit 182 and an operation handling unit 183 therein. .

  The consoles 181a, 181b, and 181c provide a function of operating the units 102 to 105 in the video processing apparatus. The specific output related unit identification unit 182 identifies a unit arranged on the path to each output channel. The operation handling unit 183 associates each of the consoles 181a, 181b, and 181c with the output channel. That is, the operation handling means 183 assigns the consoles 181a, 181b, and 181c for operation of units related to a certain output channel.

FIG. 32 is a diagram illustrating an example of a route to the output channel.
A connection by a broken line in the figure indicates a connection by the matrix switch 106. In FIG. 32, the unit related to the output channel 111 is the unit 102. Therefore, when the console 181a (the console A) is associated with the output channel 111, the operation of the unit 102 is performed on the console 181a (the console A). Will be assigned.

The specific output related unit identifying unit 182 and the operation handling unit 183 are configured by a microcomputer device.
FIG. 33 is a flowchart showing the function of the specific output related unit identifying means 182.

  In step S151, an input of the target output channel is received. In step S152, the output side of the matrix switch 106 connected to the position of interest (initially the input output channel) is specified. In step S153, the connected input side is specified by the intersection of the matrix switch 106. In step S154, it is checked whether or not the input side is connected to the input channel. Otherwise, since it is connected to the unit, the process proceeds to step S155. In step S155, the number of the connected unit is output. Then, paying attention to the input side of the unit, the process proceeds to step S152.

If there are a plurality of inputs for a unit, the processing from step S152 onward in FIG. 33 is repeated for each input, and all the related units are specified.
FIG. 34 is a flowchart of the operation of the operation handling means 183.

  In step S161, the operator receives input of an associated console and output channel. This input means may be provided on a console, and communication from there may be made by the operation corresponding means 183.

  In step S162, the specified output channel in step S161 is input to the specific output related unit identifying means 182 to perform the operation of FIG. In step S163, units are obtained as a result, and the designated console in step S161 is assigned to these units. In step S164, it is determined whether or not the operator's input is completed. If there is still input (designation of association), the process returns to step S161.

FIG. 35 is a diagram showing an example of units that affect the output channel.
This table shows an example of units that affect each output channel in the case of the path example shown in FIG. “N” in the table indicates irrelevant, and a unit with “1” in each output channel row indicates a unit that affects the output channel.

FIG. 36 is a diagram illustrating an example of correspondence between the console and output channels.
In the example shown in FIG. 36, the output channel 111 (output channel 1) corresponds to the console 181a (operation console A), and the output channel 112 (output channel 2) corresponds to the console 181b (operation console B). The output channel 113 (output channel 3) and the output channel 114 (output channel 4) correspond to the operation console 181c (operation console C).

  Here, when the table shown in FIG. 35 is combined with the table shown in FIG. 36, the console 181a (operator console A) is assigned for the operation of the unit 102 (unit 1), and the operator console 181b (operator console B). ) Is assigned for the operation of the unit 103 (unit 2), and the console 181c (the console C) is assigned for operation of the unit 104 (unit 3).

FIG. 37 is a diagram showing another example of correspondence between the console and output channels.
As shown in FIG. 37, a plurality of consoles can be associated with the same output channel. In the illustrated example, for example, the output channel 111 (output channel 1) corresponds to two consoles 181a and 181b (operator console A and console B).

According to the fourth embodiment described above, the console can be assigned to control the video of a specific output channel. Since the operation of the unit is intended to generate an output video, rational allocation can be easily realized.
<Fifth embodiment>
FIG. 38 is a diagram showing a characteristic part of the fifth embodiment.

  The video processing apparatus according to the fifth embodiment includes a plurality of consoles 191a, 191b, and 191c outside the main casing 101, and includes a specific output related unit identifying unit 192, an operation handling unit 193, and a corresponding memory. Means 194 are provided. In this embodiment, in addition to the components in the fourth embodiment, correspondence storage means 194 is provided.

  The correspondence storage unit 194 stores the correspondence between the console and the output channel. As an example of the contents stored in the correspondence storage unit 194, for example, a correspondence table as shown in FIG. By storing a plurality of such correspondence memories as an array, the correspondence between the console and the output channel can be accessed by an index.

FIG. 39 is a flowchart of an operation in which the operation handling unit 193 stores data in the correspondence storage unit 194.
In step S171, the storage number is input from the operator and a storage instruction is received. This input means may be provided on a console, and communication from there may be performed by the operation corresponding means 193.

In step S172, the storage number 194 is accessed using the storage number as an index, and the corresponding area is initialized (erased).
In step S173, an operation input to the operator console and the output channel associated with the operator is received. This operation input may be performed from the console as in the case of step S171.

In step S174, the corresponding additional writing input in step S173 is performed in the corresponding area of the correspondence storage unit 194 using the storage number as an index.
In step S175, the designated output channel is input to the specific output related unit identifying means 192 to be operated. In step S176, a designated console is assigned to the unit obtained as a result of step S175. In step S177, it is determined whether or not the operation input of the pair of the console and the output channel is finished. If there is still an operation input, the process proceeds to step S173, and if there is no operation input, this process ends.

FIG. 40 is a flowchart showing an operation in which the operation handling means 193 reproduces the correspondence from the correspondence storage means 194.
In step S181, the operator receives a storage number and receives a corresponding reproduction instruction. In step S182, the correspondence is read from the correspondence storage unit 194 using the storage number as an index. In step S183, the console correspondence (assignment) is executed in accordance with the read correspondence.

An example of a set of correspondences stored in the correspondence storage means 194 is as shown in FIG. 36 or FIG.
As described above, according to the fifth embodiment described above, when the video processing apparatus is used as a configuration for another application and then used again in correspondence with the original output channel and the console, it is stored in the correspondence storage means 194 in advance. The corresponding correspondence is read and the operation correspondence means 193 is operated.

Further, by providing the correspondence storage means 194 with a plurality of sets of memories, even when a plurality of associations are repeatedly used, a desired association can be achieved by simply selecting and specifying the storage.
<Sixth Embodiment>
In the sixth embodiment, the operation of the operation handling unit 183 is changed in the configuration of the fourth embodiment described above. In other words, in the sixth embodiment, when the operation of the unit that affects the target output channel is associated with the console, all of them are divided into a plurality of consoles in units rather than from one console. is there.

FIG. 41 is a flowchart showing the association operation of the operation handling means.
In step S191, the operator receives input of one or more associated consoles and an output channel. This input is performed by input means provided on the console, and communication from there is received by the operation corresponding means 183.

  In step S192, the output channel designated in step S191 is input to the specific output related unit identifying means 182 to perform the operation shown in FIG. In step S193, it is determined whether there are a plurality of obtained units. If there is one, the process proceeds to step S196, and all designated consoles are assigned to the unit.

  If there are a plurality of units affecting the corresponding output channel, the process proceeds from step S193 to step S194. In step S194, the operator is caused to perform operation input regarding which of the operation consoles previously input is assigned to each unit. In step S195, the console is assigned to the unit according to the input in step S194.

  In step S197, it is determined whether or not the operator's input is completed. If there is an input (designation of association), the process returns to step S191. If the input is completed, the operation corresponding to each console is terminated.

Next, an example of operation result assignment in the sixth embodiment is shown.
FIG. 42 is a diagram showing another example of a route to the output channel, and FIG. 43 is a diagram showing another example of a unit that affects each output channel.

  In the table of FIG. 43, a column in which a numerical value is written indicates a unit that affects the output channel. The numerical values indicate the order followed from the output side. Since the numerical value itself is not particularly used later, the same value is used in each output channel.

FIG. 44 is a diagram showing a correspondence example of a plurality of consoles.
44 corresponds to FIG. 43 and shows an example in which a plurality of consoles are associated. According to the illustrated example, two consoles 181a, 181b (operators A, B) are associated with the output channel 111 (output channel 1), and output channels 112, 113, 114 (output channel 2, output channel). 3, an output channel 4) is associated with an operation console 181c (operation console C). Since the output channel 111 (output channel 1) is related to the unit 102 and the unit 104 (unit 1, unit 3), an operation console 181a (operation console A) is assigned to the unit 102 (unit 1). A console 181b (a console B) is assigned to (unit 3).

Here, the unit associated with the output channel showed two cases are the same even when the number still larger, it is possible assign abuts a plurality of units in a single console.
According to the operation of the operation handling means as described above with reference to FIG. 41, the assignment target of the console can be limited to units that affect a specific output channel and can be assigned to some of the units. .

With the assignment as described above, control related to one route can be shared by a plurality of consoles. An environment with excellent operability can be easily realized compared to assigning multiple consoles without uniformity.
<Seventh embodiment>
In the seventh embodiment, in the configuration of the above-described third embodiment, the operation of the assignment management unit 172 is changed to have a function of assigning an operation console for each function in the unit.

FIG. 45 is a diagram for explaining a plurality of functions in the unit.
The unit 201 in FIG. 45 is configured to be divided into two parts according to its function. Reference numerals 202 and 203 in the figure conceptually indicate two functions in the unit 201. Reference numeral 204 denotes a control communication path for receiving control.

  The unit 201 is controlled by a set of microcomputers that operate in communication with the control communication path 204, and two tasks that operate on the CPU correspond to the function 202 (function 1) and the function 203 (function 2).

  Alternatively, these functions 202 and 203 may be distinguished from each other by connecting different hardware (ports) for each function to the microcomputer without separation as a task.

  Alternatively, these functions 202 and 203 may have independent functions inside the unit, even if not from the viewpoint of the CPU. For example, it is connected to the internal bus through the necessary conversion from the control communication path, and a plurality of hardware is connected to the internal bus, and the function division such as one switching operation, one data writing, etc. It becomes an application object of this invention.

The present embodiment relates to a single physical unit that is divided and controlled by a plurality of functions.
FIG. 46 is a diagram for explaining a plurality of functions in the unit, assignment of an operation console to the function, and communication for control thereof.

  For example, two consoles 205a and 205b (operation consoles A and B) are connected to the assignment management means 206, respectively. This assignment management means 206 assigns each console 205a, 205b for operation of the unit 201 or the functions 202, 203 in the unit 201. Reference numerals 207 and 208 denote images of the contents of control communication. Reference numeral 209 denotes a communication path from the assignment management means 206 to the unit 201.

  Here, the assignment management means 206 assigns the console 205a (operator console A) to the function 202 (function 1) of the unit 201 and the console 205b (operator console B) to the function 203 (function 2) of the unit 201. And The assignment management means 206 sends communication from the console 205a to the function 202 and sends communication from the console 205b to the function 203 according to the assignment.

  Communication from the console 205a is sent as control communication contents 207 to the unit 201 via the communication path 209, but the assignment management means 206 puts a description of “function 1” as the destination at the head. Similarly, in the communication from the console 205b, the destination “function 2” information is added to the head by the assignment management means 206 as the control communication content 208.

When the unit 201 receives the control communication content, the unit 201 reads the destination described at the top of the content, determines which function the communication is for, and distributes it.
Similarly, the communication from the function of the unit 201 to the console includes information indicating the function of the transmission source, and is transmitted by the assignment management means 206 to the corresponding console.

Next, the exchange of function assignment control communication by such assignment management means will be described.
FIG. 47 is a diagram showing an example of a transfer table built in the assignment management means.

  According to this transfer table example, there are three units, “unit 1” has its “function 1” and “function 2”, and “unit 2” has its “function 1” and “function 2”. “Function 3” has “Function 1” in “Unit 3”. The console is assigned to these functions. There are three consoles A, B, and C. “Unit 1” is assigned “Function 1” and “Function 2” is assigned “Operation console B”. “Operation console A” is assigned to “Function 1” of “Unit 2”, “Operation console B” is assigned to “Function 2”, and “Operation console B” is assigned to “Function 3”. Then, “operation console C” is assigned to “function 1” of “unit 3”.

In this example, the same console is assigned to a plurality of functions, but it is of course possible to use different consoles depending on the configuration.
FIG. 48 is a flowchart for processing transmission from the unit to the console by the assignment management means.

  In step S201, the unit number of the transmission source is N, and the function number is M. In step S202, N and M refer to the transfer table to obtain a corresponding console. In step S203, the received content data of S201 is transmitted to the acquired console.

FIG. 49 is a flowchart for processing transmission from the console to the unit by the assignment management means.
In step S211, S is received from the console and the identifier of the transmission source console is S. In step S212, the transfer table is referred to by S, and the corresponding unit and function number are acquired. In step S213, a function number is added as destination information to the data to be transferred. In step S214, the data is transmitted to the corresponding unit.

  The assignment storage means stores assignments to the console and functions so that the assignment management means can be reproduced later. The set of information to be stored is the same as the contents of the transfer table shown in FIG. The storage and reproduction operations are the same as those in the third embodiment.

According to the seventh embodiment described above, even when there are a plurality of independent functions in the unit, it is possible to assign an operation console to the functions and construct an environment with excellent operability. Moreover, the trouble of reassignment can be saved by storing and reproducing the assignment.
<Eighth Embodiment>
FIG. 50 is a diagram showing the characteristic part of the eighth embodiment.

  In FIG. 50, a matrix control console 211 is provided outside the main housing 101, and a connection storage means 212 is provided therein. The matrix control console 211 provides a control operation function of the intersection of the matrix switch 106. Here, a user interface based on GUI (Graphical User Interface) is provided.

  The connection storage means 212 stores and holds the destination connected to each input and output of the matrix switch 106. The connection destination is the input / output or input channel or output channel of the unit.

51A and 51B are diagrams showing examples of stored contents of the connection storage unit 212, where FIG. 51A shows an example of an input connection destination, and FIG. 51B shows an example of an output connection destination.
According to the stored content example shown in FIG. 51, the matrix switch 106 has 10 inputs from s0 to s9, and the respective connection destinations are stored. Since s9 has no connection destination, NONE (none) is stored.

Similarly, the matrix switch 106 has 10 outputs from d0 to d9, and each connection destination is stored.
The conventional video processing apparatus does not have the connection storage means 212. Therefore, the operation of the intersection of the matrix switch 106 must be controlled by designating the intersection by the input / output name of the matrix switch 106. For example, an operation such as selecting the input s4 as the output d0 is necessary.

On the other hand, in this embodiment, by referring to the connection storage unit 212, it is possible to provide an operation environment that is easy for the operator to understand.
FIG. 52 is a diagram showing a display example using a GUI of the matrix control console 211, where (A) shows an example of an input screen for route connection, and (B) shows an example of another input screen for route connection. .

  FIG. 52A shows an example of a display screen for selecting an object to be connected to the output channel 1. This input screen is provided with a GUI radio button 213, and only one of the nine radio buttons is selected here. The input screen also includes a “stop” GUI input button 214 and a “continue” GUI input button 215. The input button 214 is operated when the process is stopped (pressed (clicked) on the GUI). The input button 215 is operated when processing is continued with the selected radio button.

  In the state shown in FIG. 52A, the output 1 radio button of the unit 1 is selected. Thus, when the “continue” input button 215 is pressed, the intersection of the matrix switch 106 is controlled so that the output 1 of the unit 1 is connected to the output channel 1.

  In the example shown in FIG. 51, the output channel 1 is connected to the output d0 of the matrix switch 106, and the output 1 of the unit 1 is connected to the input s4 of the matrix switch 106. Therefore, the intersection is controlled so that the input s4 is connected to the output d0.

FIG. 52B shows a display screen for selecting a target to be connected to the input 2 of the unit 3. The components on the screen are the same as (A).
In FIG. 52B, since the input channel 4 is selected, if this is continued, the input channel 4 is connected to the input 2 of the unit 3.

  In the example shown in FIG. 51, the input 2 of the unit 3 is connected to the output d8 of the matrix switch 106, and the input channel 4 is connected to the input s3 of the matrix switch 106. Therefore, the intersection is controlled so that the input s3 is connected to the output d8.

Thus, by providing the connection storage means 212, a specific connection destination is displayed, and the matrix switch 106 can be controlled.
FIG. 53 is a flowchart of operation input and control operation in the matrix control console.

  In step S221, a variable K indicating the output side number of the matrix switch 106 is initialized to zero. In step S222, the connection storage means 212 is referred to, and the name of the destination connected to dK is S. dK is d0 if K = 0.

  In step S223, an input request for an object to be connected to S is received. That is, all the connection destinations on the input side of the connection storage unit 212 are referred to, and an input screen as shown in FIG. 52 is displayed. On the input screen, all connection destinations on the input side are displayed as candidates for radio button selection. The operator sees the display, selects a radio button, and operates the stop or continue button.

In step S224, the process branches depending on whether the button input is continued or stopped. If it is canceled, the process ends. In the case of continuing, the process proceeds to step S225.
In step S225, the selected input side is numbered as I. For example, in the example of FIG. 51, if the output 1 of the unit 1 is the input s4, I is 4.

  In step S226, the matrix switch 106 is controlled so that only the intersection of the input side I is turned on for the output side K. For example, when K is 0 and I is 4, control is performed so that s4 is connected to d0.

In step S227, 1 is added to K.
In step S228, it is determined whether or not the Kth exists on the output side, and if present, the process proceeds to step S222. If it does not exist, the process ends. In the example of FIGS. 1 and 51, since there are 0 to 9 on the output side, the process ends when K becomes 10. That is, the input side selection on all output sides has been completed.

According to the eighth embodiment described above, the operator can easily select the connection destination without knowledge of the connection status of the matrix switch 106, and the operability is improved.
In the above description, the matrix control console 211 is provided with a GUI operation environment. However, the present invention is not limited to this. For example, a character string display LED is combined with a physical switch to display a character string. A display and selection function may be realized.
<Ninth embodiment>
FIG. 54 is a diagram showing the characteristic part of the ninth embodiment.

  In FIG. 54, a matrix control console 221 is provided outside the main housing 101, and a connection storage means 222 is provided therein. The matrix control console 221 has inspection means 223.

The matrix control console 221 provides a control operation function of the intersection of the matrix switch 106. Here, it is assumed that a user interface by GUI is provided.
The connection storage means 222 stores and holds the destination connected to each input and output of the matrix switch 106. The connection destination is the input / output or input channel or output channel of the unit.

  The inspection means 223 shows one function of the matrix control console 221, and checks whether there is a problem in the path configured as a result of the matrix control operation by the matrix control console 221, and warns if there is a problem. It has a function to emit.

  The matrix switch 106 connects each input and output with an arbitrary setting of the matrix. Each output is connected to any one of the inputs. A route inside the video processing apparatus is created by setting the matrix switch 106.

  All combinations of matrix switch 106 settings do not provide a path for proper operation, and in some cases there may be settings that do not work, or even settings that cause the device to fail. For example, if a video processing unit with one input and one output is connected to its input by a matrix switch, it becomes a complete feedback loop, has no function to the outside world, and may even destroy the unit in some cases . Such a setting can occur due to an incorrect control operation.

  In this configuration, the control operation is not immediately executed, and it is checked whether or not there is a problem by the inspection means before the execution, and the setting is executed as it is only when there is no problem. If there is a problem, issue a warning. In the inspection, the connection storage unit 222 is referred to, an object connected to each input / output of the matrix switch 106 is acquired, a path constituted as a result of control is determined, and the inspection is performed.

FIG. 55 is a flowchart showing the function of the inspection means 223.
In step S231, a control operation is received by the matrix control console 221. In step S232, the path that is generated as a result of the operation is logically traced to check whether there is a problem. In step S233, it is determined whether there is a problem.

If there is no problem, the process proceeds to step S236, and the matrix switch 106 is set.
If there is a problem, the process proceeds to step S234, and a warning is displayed. If it is on the GUI, a warning screen is displayed, and the warning content is displayed as a character string and an image. In step S235, an input of a correction operation for the warning is received.

After the correction operation, the process is repeated again from step S232, and if there is no problem in the created path, the matrix switch 106 is set as it is in step S236.
The warning issue varies depending on the configuration of the apparatus. In the case of a unit that does not output unless there is an input by a unit in the apparatus, if the output is used, it is a warning target if there is no input.

Further, an input or output of the matrix switch 106 that is not connected to anything is subject to a warning only by using it.
Also, if the format of the video signal to be transmitted is different for each unit or input channel and output channel, a problem arises when a path with a different format is connected, and this is a warning target.

  When issuing a warning, it is helpful to the operator if the contents of the problem and the countermeasures are displayed, but when realizing the device at a low cost, only the warning is indicated by a buzzer or lamp, and the content display is omitted. However, the effect of the present invention can be exhibited.

  Alternatively, a similar effect can be obtained even if an apparatus that does not explicitly issue a warning and does not accept the problematic control operation itself is configured. An effect can be obtained by selecting only a control operation having no problem and enabling input.

According to the ninth embodiment described above, an apparatus that is excellent in operability and safe is realized by preventing an erroneous setting from being performed and giving the operator an opportunity for resetting. Is done.
<Tenth Embodiment>
In the tenth embodiment, the unit can be removed and replaced in the ninth embodiment, and when the unit is attached, the contact is made via the main casing or directly by the contact. It is structured to be connected to a matrix switch.

  In this structure, since the units connected to the matrix switch are not fixed, it is impossible to check the operation of the inspection means, that is, whether there is a path problem based on the information of the fixed units. .

For this reason, the unit attached at the time of inspection is identified, and the path is inspected based on the identified information.
FIG. 56 is a diagram showing the structure of a video processing apparatus capable of detaching a unit, which is a characteristic part of the tenth embodiment.

  56, there are detachable units 231a, 231b, and 231c, which are connected to the connection board 233 by connector portions 232a, 232b, and 232c, respectively. The connection board 233 is also connected with a matrix switch 234, an input / output unit 235, and a control communication unit 236.

The input / output unit 235 is responsible for external connection of the input channel and output channel (holding of the connector).
The control communication unit 236 has a communication function and includes a connection storage unit 237. The connection storage means 237 stores connection information between the matrix switch 234 and the input and output channels, and connection information between the matrix switch 234 and the connector portions 232a, 232b, and 232c.

  The control communication unit 236 is connected to the matrix control console 238 through a communication path. The matrix control console 238 includes an inspection unit 239 having an inspection function that is a feature of the present embodiment.

FIG. 57 is a flowchart of functional processing of the inspection means 239 that identifies connected units and issues a warning to control of the matrix switch.
In step S241, the matrix control console 238 receives an input of a control operation of the matrix switch 234.

  In step S242, all units connected at that time are identified. This identification is executed by the control communication unit 236 of the video processing apparatus main body, and the result is sent to the inspection means 239 of the matrix control console 238.

  In step S243, the unit information obtained in step S242 is also used to logically follow the path that can be generated as a result of the operation, and check for problems. In step S244, it is determined whether there is a problem.

If there is no logical problem in the created path, the process proceeds to step S247, and the matrix switch 234 is set.
If there is a problem, the process proceeds to step S245, and a warning is displayed. If it is on the GUI, a warning screen is displayed, and the warning content is displayed as a character string and an image. In step S246, an input of a correction operation for the warning is received.

After the correction operation, the process is repeated again from step S243, and if there is no problem in the created path, the matrix switch 234 is set as it is in step S247.
FIG. 58 is a flowchart of another process for issuing a warning to the control of the matrix switch 234.

  In this flowchart, the inspection is not performed after the input of the control of the matrix switch 234 is completed, but the path is inspected every time the control operation for each intersection is input.

In step S251, all units connected at that time are identified.
In step S252, an operation input for controlling one intersection of the matrix switch 234 is received.

In step S253, the path constructed as a result of the control of the intersection is logically traced to check for problems.
In step S254, if there is a problem, the process proceeds to step S257, and if there is no problem, the process proceeds to step S255.

In step S255, the control input in step S252 is executed.
In step S256, it is determined whether or not the control is finished. If not finished, the process proceeds to step S252.

In step S257, a warning is displayed. In step S258, an input of a correction operation for a warning is received.
According to the tenth embodiment described above, even if the unit is replaceable, an erroneous setting is prevented from being executed in the unit configuration at the time of operation, and an opportunity for resetting is given to the operator. Thus, a device that is excellent in operability and safe is realized.
<Eleventh embodiment>
FIG. 59 is a diagram showing characteristic portions of the eleventh embodiment.

  In FIG. 59, a locking mechanism 242 is attached to the matrix control console 241 connected to the matrix switch 106. The locking mechanism 242 has a built-in switch, and the switch operates in conjunction with the unlocking and locking operations of the locking mechanism 242, and the unlocking and locking information is input to the microcomputer of the matrix control console.

  Using this unlocking and locking information input, the matrix control console 241 accepts an operation and operates only when the locking mechanism 242 is unlocked. When the locking mechanism 242 is locked, no operation is performed without accepting the operation.

  With this configuration, if a person who has authority to operate the matrix control console 241 holds and manages a key suitable for the locking mechanism 242, it prevents other persons from changing the setting of the matrix switch 106. Can do.

For the locking mechanism 242, a cylinder lock using a metal key is used. Alternatively, a card reader that reads a magnetic card can be substituted, and a magnetic card can be used instead of a key. The same locking mechanism configuration can be realized with other cards and the like.
<Twelfth embodiment>
FIG. 60 is a diagram showing characteristic portions of the twelfth embodiment.

In FIG. 60, a password input means 252 is incorporated in the matrix control console 251 connected to the matrix switch 106.
The arrangement position of the password input means 252 is not limited to this, and may be a casing independent of the matrix control console 251.

  The password input means 252 is a keyboard mechanism for inputting an alphabetic password, but may be a keyboard mechanism for inputting a numerical password only. Other known input mechanisms do not change the effect of the present invention.

In the present embodiment, the matrix control console 251 can be operated only when a correct password is input to the password input means 252.
FIG. 61 is a flowchart of processing for permitting the operation of the matrix control console 251 with a password.

In step S261, the process waits for a password. In this state, the matrix control console 251 cannot be operated.
In step S262, a password is received. Alternatively, an input of an ID character string or numerical value and a password are received in pairs.

  In step S263, it is determined whether the password is correct. In the case of a configuration in which an ID is also input, the determination is performed together with the ID. Here, it is assumed that the operation is based on a known password processing algorithm.

In step S264, if the password is correct, the process proceeds to step S265, and if not, the process proceeds to step S261.
In step S265, the control operation function of the matrix control console 251 is made available to the operator.

In step S266, an operation end input is received from the operator. Immediately thereafter, the process proceeds to step S261.
According to the twelfth embodiment described above, the operation of the matrix control console 251 can be limited to only those who know the password, and an unauthorized person can operate the matrix control console 251. can do.
<Thirteenth embodiment>
FIG. 62 is a diagram showing the characterizing portion of the thirteenth embodiment.

  According to the thirteenth embodiment, in addition to the operation functions of the consoles 261a and 261b having the operation functions of the units in the video processing apparatus outside the main housing 101, and the operation functions of the units 102 to 105, the matrix control mechanism 262 is provided. The main casing 101 has assignment management means 263.

  This assignment management means 263 has a function of assigning the consoles 261a, 261b, 261c to the units 102 to 105, and a function of relaying / transmitting / forwarding communication from the console 261c to the matrix switch 106.

FIG. 63 is a flowchart of operations for controlling the matrix switch 106 and the units 102 to 105 on the console 261c.
In step S271, an operation input is received from the operator.

  In step S272, the process branches depending on the input operation target. When the input operation target is the units 102 to 105, the process proceeds to step S274, and when the operation target is the matrix switch 106, the process proceeds to step S273.

In step S273, a control command is transmitted to the matrix switch 106.
In step S274, a control command is transmitted to units 102-105.

  The assignment management means 263 forwards the communication from the consoles 261a, 261b, 261c to a unit previously assigned to the transmission source console in the case of a control command for the unit, and in the case of a control command for the matrix switch, Transfer to matrix switch 106.

The console provided with a mechanism for controlling the matrix switch 106 can control the matrix switch 106 in addition to the operation of the video processing unit.
Preferably, when the matrix switch 106 is controlled, the operation of the video processing unit is stopped. When the control is completed and the matrix switch is set to a new setting, the video processing assigned by the assignment management means 263 is performed. It is good to be able to start the operation on the unit.

In the configuration of FIG. 62, only one console is provided with the matrix control mechanism, but a plurality of consoles may be provided with the matrix control mechanism.
<Fourteenth embodiment>
FIG. 64 is a diagram showing characteristic portions of the fourteenth embodiment.

  According to the fourteenth embodiment, in addition to the operation functions of the consoles 271a and 271b having the operation functions of the units in the video processing apparatus outside the main housing 101 and the operation functions of the units 102 to 105, the display means 272 is provided. The main casing 101 has an assignment management means 273.

The display means 272 displays information related to the setting state of the matrix switch 106.
The assignment management unit 273 has a function of assigning an operation console to units, and also has a function of relaying / transmitting / transferring communication related to a setting state from the matrix switch 106 to the operation console 271c.

FIG. 65 is a view showing a display example of the setting of the matrix switch 106.
FIG. 65 shows an example of display on the display means 272. In this example, the setting of the intersection point of the matrix switch 106 is displayed as it is. That is, for each output, which input is selected is displayed in a table format.

FIG. 66 is a diagram showing a display example of a route formed by the matrix switch 106. FIG.
The example shown in FIG. 66 is another display example of the display means 272, and the broken line portion indicates the connection realized by the matrix switch 106.

  The display of the path in FIG. 66 relates to the path determined by the setting of the intersection of the matrix switch 106, but the input channel connected to the matrix switch 106, the output channel, and the input / output information of each unit. Is used to display the path from the input channel to the output channel.

The display graphics generation method can be performed by a known GUI technique, and thus the details are omitted.
When such a display does not exist, the operator cannot know what setting the matrix switch is currently set. For this reason, it has not been possible to predict which output channel of the video processing device will change due to the effect of the operating unit. The only way was to know the current settings in advance and memorize them or write them down.

By providing the display as described above on the console, the operator can know the effect on the output by the operation unit, and the operability is improved.
Although the display of the display means 272 is always displayed, the display function may be displayed by the operator starting the display function as necessary. When the setting of the matrix switch 106 is changed, the display on the display unit 272 is updated in response to the update notification. However, the display unit 272 is periodically updated by inquiring from the console 271c where the display unit 272 exists. You may make it do.
<Fifteenth embodiment>
FIG. 67 is a diagram showing characteristic portions of the fifteenth embodiment.

  According to the video processing apparatus of the fifteenth embodiment, the path information generating means 281 connected to the matrix switch 106, and the information video output means 282 connected to the matrix switch 106 and the path information generating means 281 It has.

  The path information generation means 281 generates information on units and input channels on the path to each output channel. The information video output means 282 outputs a video of characters or symbols to each output channel.

  The route information generation means 281 generates information on the route to each output channel from the setting of the intersection of the matrix switch 106 and the information of the connected unit and the input channel.

  The information video output unit 282 obtains the route information from the route information generation unit 281 and converts it into a video of a format such as characters and outputs it to each output channel. Each output channel outputs an image of information related to the route to the output channel.

  If necessary, as another configuration, not only the path information related to a single output channel, but also information on paths reaching two or more or all of the output channels may be output as video.

FIG. 68 is a diagram showing an example of the structure of the information video output means 282.
According to the structure example of the information video output means 282 shown in FIG. 68, the information video output means 282 includes the character video generation means 283. The character video generation unit 283 generates character string information from the information obtained from the route information generation unit 281 and uses this as a video signal for output corresponding to each of the output channels 111 to 114 (outputs 1 to 4 in FIG. 68). ).

  The output channels 111 to 114 of the information video output means 282 are supplied to the matrix switch output 285 on the output side of the matrix switch 106 and the character video generation means 283 by a selection switch section 284 provided for each output channel. Is connected to the output.

  The selection switch unit 284 selects one of the matrix switch output 285 and the output from the character image generation means 283 and outputs the selected image to the output channels 111 to 114 as an image.

The operator of the video processing apparatus controls the selection switch unit 284 as necessary, and outputs a video in which path information is represented by a character string instead of a normal output video.
For example, for input channel 1, when input channels 1 and 2 are input to unit 1 and the output of unit 1 is connected to output channel 1, the following character string is output as a video.
“Output channel 1: Unit 1 output 1,
Unit 1 input 1: Input channel 1,
Unit 1 Input 2: Input Channel 2 "
FIG. 69 is a diagram showing another example of the structure of the information video output means 282.

  In the structure of the information video output means 282 illustrated in FIG. 69, as a video of the output channel, a video that is completely switched to either the matrix switch output 285 or the output from the character video generation means 283 is not output. Instead, they are superimposed and output.

  Therefore, the information video output unit 282 includes a superimposing unit 286 in each of the output channels 111 to 114. The superimposing unit 286 has a function of superimposing and outputting the output from the character image generating unit 283 on the matrix switch output 285. In the non-superimposed state, the image of the matrix switch output 285 is sent as it is to the corresponding output channel.

The operator of the video processing apparatus operates the superimposing unit 286 as necessary.
In the above description, the generated video of the information video output means 282 is described by characters. However, symbols, figures, images, etc. may be determined in advance for each unit and input channel, and the enumeration may be visualized and output as route information. .

Furthermore, it is preferable to generate and output a path information image in a display format as shown in FIG.
According to the present embodiment, by outputting or superimposing the processing path information on the output video itself, the operator can understand the path information without misunderstanding.
<Sixteenth Embodiment>
FIG. 70 is a view showing the characterizing portion of the sixteenth embodiment.

  In FIG. 70, reference numeral 291 denotes information transmission means for transmitting the current setting of the matrix switch 106, that is, information regarding the state of the intersection or information regarding the resulting route. A communication path 292 is connected to the information transmission means 291, and a plurality of display means 293 a and 293 b are connected to the communication path 292.

Information transmitted from the information transmission unit 291 is received by the display units 293a and 293b via the communication path 292 and displayed on the display units 293a and 293b, respectively.
The display content is the same as that of the display means 272 of the fourteenth embodiment, and for example, the display example shown in FIG. 65 or 66 can be used.

  The number of display means connected to the communication path 292 is two in the illustrated example, but is not limited to this, and any number is possible. The communication path 292 is preferably wired, but is not limited to this, and can be configured using radio.

  In the plurality of display means, the display form or display contents may be different from each other. Furthermore, the information transmission unit 291 may transmit different information for each destination display unit, or the received content may be selected and processed by the display unit.

  According to the present embodiment, the route information is displayed on the display means 293a and 293b via the communication path 292, so that the source of the current output video can be obtained even at a location away from the video processing device or its console. And information on processing can be obtained.

Further, since the display means 293a and 293b can be constructed at a relatively low cost compared to an operation console or the like, a large number of displays can be provided at a low cost.
<Seventeenth embodiment>
FIG. 71 is a diagram showing characteristic portions of the seventeenth embodiment.

  In FIG. 71, consoles 301a, 301b, and 301c are connected to an assignment management unit 303 via a network (LAN: Local Area Network) 302. Each of the consoles 301a, 301b, and 301c is given network identifiers 304a, 304b, and 304c that represent the identifiers of the respective consoles as nodes of the network 302.

  In the illustrated example, “pan1.net0” is given as the network identifier 304a of the console 301a, “pan2.net0” is given as the network identifier 304b of the console 301b, and as the network identifier 304c of the console 301c, “Pan3.net0” is given.

Since the assignment management means 303 is also connected to the network 302, it is given a network identifier.
The assignment management means 303 has a built-in transfer table that holds assignments to the console unit by the network identifier of the console. An example of the transfer table is shown in FIG.

FIG. 72 is a diagram showing an example of the transfer table of the assignment management means 303.
72, the console 301a (operation console A) in FIG. 71 is assigned to the unit 102 (unit 1) and the unit 103 (unit 2), and the operation console 301b (operation console B). ) Is assigned to the unit 104 (unit 3), and the console 301c (operator C) is assigned to the unit 105 (unit 4).

FIG. 73 is a flowchart showing the operation of transmission processing from the unit of the assignment management means to the console.
In step S281, transmission data is received from the unit side, and the unit number of the transmission source is set to N.

  In step S282, the transfer table is referred to by unit number N, and the network identifier of the corresponding console is acquired. For example, when N is 4, the network identifier “pan3.net0” is obtained in the example of FIG.

In step S283, the transmission data received from the unit is transferred via the network with the network identifier obtained in step S282 as the destination.
FIG. 74 is a flowchart showing the operation of transmission processing from the console of the assignment management means to the unit.

In step S291, transmission data is received from the console via the network, and the transmission source console network identifier is set to S.
In step S292, the transfer table is referred to by the console network identifier S to obtain a corresponding unit number. For example, when the console network identifier S is “pan1.net0”, “1” and “2” are obtained as unit numbers in the example of FIG.

  In step S293, the data received in step S291 is transferred to the corresponding unit. In the above example, the assignment management means 303 transfers the received data from the console 301a (the console A) to both the unit 102 (unit 1) and the unit 103 (unit 2).

FIG. 75 is a flowchart of the transmission process to the assignment management means of the console.
In step S301, data to be transmitted is prepared by an operation input by the operator.
In step S302, the network identifier of the console itself is added to the data to be transmitted.

In step S303, it transmits to the allocation management means 303 via a network.
In the above example, there is only one console assigned to a certain unit, but it may be configured to allow assignment of a plurality of consoles. At that time, the transmission from the unit to the console is forwarded to all assigned consoles.

According to this embodiment, it is not necessary to extend a communication cable from the main housing for each console, and by attaching the console to the network, a plurality of consoles can be provided without the need for extra wiring. In such a case, the assignment of the console to the units can be freely set, and processing can be performed without interference.
<Eighteenth embodiment>
The configuration of the characteristic part of the eighteenth embodiment is the same as the configuration shown in FIG. 71 as in the seventeenth embodiment.

  In the seventeenth embodiment, the assignment management means 303 holds and processes the correspondence between the console and units in the transfer table. In the eighteenth embodiment, a unit corresponding to the console is notified in advance, and transmission is performed by designating a destination unit from the console.

Here, the operation will be described with reference to FIG. 71 on the assumption that each unit has its number as an identifier.
FIG. 76 is a flowchart of the assignment operation of the assignment manager 303.

In step S311, the operator inputs an instruction to assign an operation console to the unit. This input itself may be performed from one of the consoles, for example.
In step S312, for each unit, the unit identifier is notified (transmitted) to the console assigned to the unit. The console stores the notified identifier.

In step S313, it is determined whether or not the operator's input is completed. If there is a continuous input, the process returns to step S311.
FIG. 77 is a flowchart showing the operation of the console during transmission processing from the console to the unit.

In step S321, transmission data is prepared by an operation input by the operator.
In step S322, the network identifier of the console itself and the unit identifier (unit number) notified in advance are added to the transmission data.

In step S323, it transmits to the allocation management means 303 via a network.
FIG. 78 is a flowchart showing the operation of the assignment management means 303 during the transmission process from the console to the unit.

In step S331, transmission data from the console is received via the network.
In step S332, the identifier of the transmission destination unit in the received data is read.
In step S333, the received data is transferred to the corresponding unit.

  Since the transmission process from the unit to the console is performed by the same process, the description thereof is omitted. Communication between the console and the unit begins with transmission from the console to the unit. At this time, since the network identifier of the console itself is added to the transmission data and sent to the unit, the unit can obtain the network identifier of the assigned console (to be transmitted).

FIG. 79 is a diagram showing a characteristic portion of another configuration example of the eighteenth embodiment.
According to another configuration example of the eighteenth embodiment, the consoles 311a, 311b, and 311c are connected to the relay unit 313 via a network (LAN) 312. Each of the consoles 311a, 311b, and 311c is provided with network identifiers 314a, 314b, and 314c representing the identifiers of the respective consoles as nodes of the network 312.

  Inside the main housing 101, the units 315, 316, 317 and 318 are connected to the internal network 319. Each of the units 315, 316, 317, and 318 is provided with unit identifiers 320, 321, 322, and 323 for identifying each unit as a node of the internal network 319. The internal network 319 is also connected to the relay unit 313 and the assignment management unit 324.

  The relay unit 313 connects the network 312 and the internal network 319. The relay unit 313 only performs simple communication transfer, and does not process communication contents.

Note that when realizing the present embodiment, the network 312 and the internal network 319 may be networks using the same technology, and the relay unit 313 may be omitted.
In the configuration of FIG. 79, communication between the consoles 311a, 311b, 311c and the units 315 to 318 is performed directly via the network 312 and the internal network 319 without going through the assignment management means 324.

Also in the configuration of FIG. 79, the allocation operation of the allocation management means 324 is performed according to the flowchart shown in FIG.
Further, in the configuration of FIG. 79, the allocation management means 324 does not need to be in a special position on the network, and any component (node) on the network is responsible for the allocation operation of FIG. But there is no problem.

FIG. 80 is a flowchart of the operation of the console that performs transmission to the unit in the configuration of FIG.
In step S341, transmission data is prepared.
In step S342, the network identifier of the console itself is added to the transmission data.

  In step S343, the transmission destination via the network is designated by the previously notified unit identifier, and transmission is performed. The transmitted data is received by the destination unit without going through the assignment management means 324.

  In the present embodiment, the units 315, 316, 317, and 318 and the main casing 101 that holds the units 315, 316, and 318 do not have to be integrated, but are physically divided into a plurality of units. It may be connected. In this case, the location on the network can be specified by the identifier.

Further, the transmission from the consoles 311a, 311b, 311c is given the network identifier of the console itself in preparation for the necessity of a reply or retransmission due to a problem on the network.
<Nineteenth embodiment>
FIG. 81 is a diagram showing characteristic portions of the nineteenth embodiment.

  In the nineteenth embodiment, the consoles 331a, 331b, 331c are connected to the units 102 to 105 via the assignment management means 332. Each console 331a, 331b, 331c is assigned a console identifier (A, B, C). Further, each unit 102 to 105 is assigned a number (1, 2, 3, 4) as an identifier, and is specified by this.

In the configuration of FIG. 81, the consoles 331a, 331b, and 331c are connected to the assignment management unit 332, respectively, but may be connected via a network.
Next, an operation that is a feature of the allocation management unit 332 will be described.

FIG. 82 is a flowchart for processing transmission from the console to the unit.
In step S351, the transmission data from the consoles 331a, 331b, and 331c is received, the console identifier of the transmission source is S, and the identifier of the unit that is the transmission destination is U. The console identifier is A, B, or C in FIG. The unit identifier is the number 1, 2, 3, or 4 in FIG. In the present embodiment, these pieces of information are included in the received data. The format of the communication data here includes a destination unit identifier 333, a transmission source console identifier 334, and a transmission data main body 335, as shown in FIG.

In step S352, the assignment management means 332 refers to the built-in transfer table using the console identifier S as a key.
As shown in FIG. 84, the transfer table stores the console assigned to the unit by the console identifier. Although the communication data here includes a destination unit identifier, it is not transferred as it is, but is compared with the contents of the transfer table.

  In step S353, it is determined whether or not the operator console identifier S of the transmission source is assigned to the unit of the identifier U in the transfer table. If assigned, the process proceeds to step S355. Otherwise, the process proceeds to step S354.

In step S354, since the operator console identifier S of the transmission source is not assigned to the unit of the identifier U, the communication is discarded and the process ends.
In step S355, since the transmission source console identifier S is assigned to the unit of identifier U, the communication data is transferred to the unit of identifier U.

  For example, if the transmission source console identifier S is “A” and the unit identifier U is “1” in step S353, the unit 102 (unit 1) is received because it is assigned in the transfer table of FIG. Data will be transferred.

  If the transmission source console identifier S is “A” and the identifier U is “3” in step S353, the assignment does not coincide with the assignment in the transfer table of FIG. Discard.

  According to the present embodiment described above, control from a console other than the assigned console is impossible. After the assignment is decided, even if a console is additionally connected, the unit cannot be operated from that console.

In addition, the present embodiment can be applied almost in the same manner even with the configuration of FIG.
In addition, in order to implement | achieve the effect of this Embodiment, another structure demonstrated below is also possible.

  That is, an identifier of a console that accepts communication (that is, assigned) is stored in the unit in advance. Here, each unit and each console may be connected via a network.

  When transmission is performed from the console to the unit, the received unit checks whether the transmission console matches the previously stored console. If they match, the received data is processed. If they do not match, the received data is discarded without being processed.

There may be a plurality of console identifiers stored in advance in the unit. If there are more than one, check if the source matches one of them.
Next, a video processing system implemented by configuring a plurality of video processing devices will be described.
<20th Embodiment>
FIG. 85 is a diagram showing characteristic portions of the twentieth embodiment.

The video processing devices 341 a, 341 b, and 341 c are interconnected to the common control communication path 345. Further, a matrix control console 346 is connected to the common control communication path 345, and an inter-device connection storage unit 347 is connected to the matrix control console 346.

The inter-device connection storage unit 347 stores the connection between the video processing devices 341a, 341b, and 341c.
The matrix control console 346 controls the matrix switches 343a, 343b, and 343c of the video processing devices 341a, 341b, and 341c. The storage in the inter-device connection storage unit 347 is read out by the matrix control console 346.

  For each video processing device 341a, 341b, 341c, their connection storage means 342a, 342b, 342c stores the objects connected to the input / output of the matrix switches 343a, 343b, 343c. The target is the input / output and input channels and output channels of the units in the video processing apparatus. The communication control means 344a, 344b, 344c serve as connection ports to the common control communication path 345.

  In the above configuration, device numbers are assigned to the video processing devices 341a, 341b, and 341c. Here, it is assumed that the video processing device 341a is a device number “1”, the video processing device 341b is a device number “2”, and the video processing device 341c is a device number “3”.

In the example of FIG. 85, there are several connections between the output channel of the video processing device and the input channel of another video processing device.
By configuring such a system, it is possible to perform more complicated processing on the video than is possible with only a single video processing device. In addition, by moving the video processing apparatus to different locations according to the situation and using them separately, or using them in combination as shown in FIG. 85, various costs can be saved without preparing extra equipment. A system can be realized.

In the present invention, the purpose is to improve the operability of such a system, and each video processing apparatus is not individually controlled and operated, but can be controlled uniformly.
The matrix control console 346 refers to the storage of the inter-device connection storage means 347, and provides a control operation function based on the overall video path by the control of each matrix switch. The matrix control console 346 has GUI display and operation input functions.

  The output channels “1” and “2” of the video processing device 341a are connected to the input channels “3” and “4” of the video processing device 341b. The output channels “3” and “4” of the video processing device 341a are connected to the input channels “3” and “4” of the video processing device 341c. The output channels “3” and “4” of the video processing device 341b are connected to the input channels “1” and “2” of the video processing device 341c. Information on these connections is stored in the inter-device connection storage unit 347.

FIG. 86 is a diagram showing a storage example of the inter-device connection storage means 347.
The inter-device connection storage unit 347 stores connection information between video processing devices in a table format as shown in the figure. In this table, each row shows one connection, the left side is information about the video processing device that is the source of the video signal and its output channel, and the right side is the video processing device that is the destination (receiving side) of the video signal. And its input channel information.

The storage example of FIG. 86 has the contents stored in the connection example of FIG.
FIG. 87 is a flowchart for explaining the operation of the matrix control console 346.
In step S361, the matrix control console 346 reads the inter-device connection from the inter-device connection storage unit 347.

  In step S362, a GUI screen for receiving an operation input for controlling the matrix switch of each video processing device is displayed using the information read in step S361. And the operation input with respect to it is received.

  In step S363, communication for controlling the matrix switch is performed with the corresponding device in accordance with the operation input. This communication is performed to the corresponding video processing apparatus via the common control communication path 345.

FIG. 88 is a diagram showing an example of the operation input GUI screen.
The screen illustrated in FIG. 88 is prepared by referring to the inter-device connection storage unit 347. This screen displays “Please input the object to be connected to the output channel 1 of the device number 2”, and inputs the control for the matrix switch 343b of the video processing device 341b whose device number is “2”. It is a screen for. That is, the video source to the output channel 1 of the video processing device 341b is selected.

On this screen, a cancel button 351 and a continuation button 352 are provided, and these are GUI buttons for inputting processing stop and continuation, respectively.
Reference numerals 353 and 354 denote radio buttons, and only one of them can be exclusively selected. Since the radio buttons 353 and 354 are video sources that can be used by the video processing device 341b, either the output of the built-in unit or the input channel of the video processing device 341b can be selected. In the illustrated example, the radio button 353 of “unit 1 output 1” is selected.

  Here, as can be seen from FIG. 85 or 86, the input channels “3” and “4” of the video processing device 341b are connected to the output channels “1” and “2” of the video processing device 341a. This information is stored in the inter-device connection storage means 347 in the format as shown in FIG.

  The matrix control console 346 uses this information in place of (in addition to) displaying the input channels “3” and “4” on the display screen of FIG. 88, and the video processing device 341 a (device number “ “1”) and “2” of the output channel of “1”) are displayed.

  When the operator selects “output 2 of device 1” in the GUI of FIG. 88, the matrix switch 343b is controlled to “connect input channel 4 to output channel 1”.

The operation input process as described above is performed for each output side of the matrix switch, and the intersection is set in the connection storage means.
According to the present embodiment, as described above, the operator can recognize the connection between the video processing devices and control the matrix switch of each video processing device.

FIG. 89 is a diagram showing a modification of the operation input screen.
When displaying this operation input screen, the matrix control console 346 acquires the contents of the connection storage means 342a and uses them for display.

  In the radio button 354 of FIG. 88, the explanatory text is “Output 1 of the apparatus 1”. The matrix control console 346 acquires from the connection storage means 342a the destination to which “the output channel 1 of the device 1” has already been connected. Here, it is assumed that it is “output 1 of the unit 3 built in the apparatus 1”, and this is displayed as an explanatory text of the radio button 355.

Similarly, “output 2 of device 1” is displayed in FIG. 89 as “output 2 of unit 4 of device 1”.
In the operation input screen described above, an example is shown in which settings are specified from the output side of each matrix switch. However, the present invention is not limited to this, and a user interface for specifying and inputting a route from the input side It is also possible to do.

Also, an environment in which a plurality of screens as shown in FIG.
Alternatively, a more graphical input screen may be prepared and an input method may be used in which routes are connected by dragging a pointing device. For example, a display as shown in FIG. 32 may be displayed including the connection of a plurality of video processing means, and the connection at the intersection of each matrix switch may be input by a pointing device.

Further, in the example of FIG. 85, one matrix control console 346 is provided in the system, but a plurality of matrix control consoles 346 may be provided so that the matrix switch can be operated from a plurality of locations.
The display referring to the inter-device connection storage unit 347 is not limited to the case where operation input is performed, and may be displayed in various forms at all times or as needed for the purpose of providing information to the operator.

The writing to the inter-device connection storage means 347 can be manually input by the operator when the video processing devices are connected.
Preferably, all the video processing devices are controlled from a matrix control console or the like, and a test signal is output only from a certain output channel of a certain video processing device, and reception of a signal is detected in an input channel of all the video processing devices. By doing so, it is possible to automatically detect the connection between the video processing devices. If this operation is repeated for all output channels of all video processing devices, all connections can be detected. The results are collected at the matrix control console and written to the inter-device connection storage means 347.

  The inter-device connection storage unit 347 does not need to store information from system startup. The interconnection information between the video processing apparatuses may be written for the first time when the information is required at the matrix control console. Even if the inter-device connection storage means 347 is configured as temporary storage, the present invention can be realized and a unified operation environment of matrix switches of a plurality of video processing devices can be realized.

  In the above description, the case where the matrix control console includes the GUI has been described, but a configuration without the GUI may be employed. If there is an area for displaying characters in addition to the switch on the desktop, the present invention can be realized.

As an alternative to the connection storage means, there may be provided a means for checking a unit connected to the input / output of the matrix switch by an inquiry using a signal line connected to other than the video signal and returning the result.

As shown in the figure, the board accommodated in the housing 417 includes a board computer, a matrix switch, a unit for synthesis processing, a unit for digital processing, a unit for synchronization adjustment, a disk recording device, and a unit for format conversion. and so on. These board computers, matrix switches, and other various units are connected to each other via an internal network 418. Ethernet is used for the internal network 418. The matrix switch is connected to each unit by a video signal path 419. The video processing apparatus main body 416 is connected to a plurality of output channels 420 and a plurality of input channels 421.

Furthermore, the video processing device main bodies 422 and 423 are connected to the Ethernet 411, and these have the same configuration as the video processing device main body 416.
Each board computer includes a CPU, a ROM, a RAM, various input / outputs, a network interface, a timer, and the like.

  The console 412 has an operation function of a unit inside one of the video processing apparatus main bodies and an operation function of a matrix switch. The console 412 uses an X-Window system as a GUI and provides various operation screens. Of course, other GUI systems may be used.

The GUI can be operated by a touch panel function provided in the LCD, and can be supplementarily operated by a mouse.
The console 412 includes a volatile memory and a nonvolatile memory on a built-in x86 single board computer, and various settings and the like are stored therein. Thereby, it is possible to hold various setting data until after the power is turned off. Various settings stored in the memory can be stored in a DOS format disk medium by a floppy disk drive. It is also possible to mount a storage medium in the PCMCIA slot and record various settings there.

The console 413 includes an interface that matches the communication interface of the physical switch console 414.
