  7 is a block diagram of the main part of the program transmission control system 100 according to this embodiment, and FIG. 8 is a main part software module configuration of the program transmission control system 100.

  That is, the program transmission control system 100 includes an automation control block 10 for controlling programmed program transmission installed as a software block installed in a first computer device (Automation Ctrl PC) 110, and a second computer. The news room control system (NRCS: News Room Computer System) which has a news room control system function for managing and managing news programs, from gathering arrangements installed as software blocks installed in the device 120 to material ordering and program configuration creation. ) MOS device in the block 20 and the MOS device block 30 which is a controlled video device connected to the network connected to the second computer device 120, that is, a playout server 31, CG / stills The automation control device in the automation control device block 40 that is network-connected to the first computer device 110 such as a switch 32, a switcher 41, a device controller (DCU) 42, a clip server 43 , An audio server 44, a video tape recorder (VTR) 45, a remote control camera (Robotics Camera) 46, a mixer (Audio Mixer) 47, a control unit (SCU) 130 having a video reference input, and the above control A communication path 140 connecting the unit 130 and the first computer device 110, and a network 150 connecting the first computer device 110 and the second computer device 120, and the control unit (SCU). ) 130 is a video signal via the communication path 140. An event executor (Event Executor) 105E, which is an execution management module for sending a reference (Ref. In) from the control unit (SCU) 130 to the first computer device 110, is mounted on the first computer device 110. A software module for managing the playlist information, a device driver software module corresponding to the controlled video device, a software interface to which the device driver software module can be added, and the control unit ( The event execution module having a software interface with the device control module in the (SCU) 130 is mounted.

  The event executor 105E is a software module that operates on the microcomputer of the control unit (SCU) 130.

  Ref. In is a reference input, and a reference signal (for example, a black burst signal) of the entire equipment is supplied to the control unit (SCU) 130.

  The control unit (SCU) 130 is configured to interrupt the built-in microcomputer at intervals of one field by a reference signal.

  When the interrupt occurs, the event executor 105E notifies other software modules on the same microcomputer, for example, a manual event controller 105F.

  At the same time, the event executor 105E notifies the first computer device (Automation Ctrl PC) 110 via the communication path 140.

  More specifically, the event executor 105E keeps the task in a wait state, receives the cancellation of the wait from the interrupt processing routine by the reference signal, resumes the task execution, and performs the above processing. When it finishes, it enters the waiting state again.

  The manual event controller 105F collects several processes at intervals of one field by receiving an interrupt notification.

  For example, the control unit (SCU) 130 includes a group of push buttons for controlling the switcher. When the control unit (SCU) 130 is pressed, a communication path is communicated to the switcher 41 that is an Automation control device in the Automation control device block 40. To send as a command. By making this transmission one field interval, there is no delay in control, and it is possible to prevent efficiency from being lowered due to excessive communication.

  The manual event controller 105F accumulates information on the pressed button, and sends it to the switcher 41 in the form of a command as the pressed information for one field in response to an interrupt notification. To do.

  The manual event controller 105F not only transmits a command to the switcher 41, but also transmits information about a pressed button to the first computer device 110 (Automation Ctrl PC) 110. .

  An event controller (Event Controller) 105B, which is a software module in the first computer device (Automation Ctrl PC) 110, controls execution of control events of various devices in accordance with playlist information. The progress of the playlist is performed according to the time code. By receiving notifications from the control unit (SCU) 130 at intervals of one field, the progress can be controlled using the clock as a clock.

  When operating in an interlaced system, one field consists of two fields, so the time code is incremented by one when the notification is received twice.

  When the time code comes to a position in the playlist information, the operation at that position (time in time code) is executed. That is, a device controller (Device Controller) that is a software module on the first computer device (Automation Ctrl PC) 110 and a device controller (Device Controller) that is a software module on the control unit (SCU) 130 are provided. An instruction in accordance with the playlist is sent to one (or more than one).

  Each device controller converts the instruction into a native protocol (control protocol for each device) of the controlled device, and transmits it from each port (RS422, Ethernet, etc.). A device such as RS422 or a dedicated LAN that is controlled by an interface that is not normally provided by a PC can be controlled by connecting to a DCU that carries the port portion of the control unit (SCU) 130. On the other hand, a device connected to a general-purpose Ethernet can be connected to a PC and controlled similarly.

  A device controller on the control unit (SCU) 130 is synchronized with a reference signal in order to control a switcher 41, a video tape recorder 45, and the like which are automation control devices in the automation control device block 40. In this program transmission control system 100, the device controlled from the first computer device (Automation Ctrl PC) 110 side also operates in synchronization with the control unit (SCU) 130 side. Can do.

  Further, the first computer device (Automation Ctrl PC) 110 does not need to be equipped with hardware for receiving a reference signal, and the cost can be reduced by using a communication path using Ethernet. Further, a flexible configuration as shown in FIGS. 3, 4, and 5 is possible, and a general-purpose product can be used when replacing the computer apparatus, which is economical.

  Since the conversion of the device connected to the control unit (SCU) 130 to the native protocol is performed by the control unit (SCU) 130, the load is not concentrated on the first computer device (Automation Ctrl PC) 110 side. By distributing the load, it is possible to control the equipment economically without delay in synchronization with the reference signal.

  In FIG. 8, a master connected to the event executor 105E is a master switcher. A master switcher is a switching device that is higher in the broadcasting station than the switcher or this system, and this system is attached to a specific studio, etc. Distribute the signal.

  The control unit (SCU) 130 receives instructions and timing from a master (Master) via a port such as GPI (General Purpose Interface).

  The GPI is a port for receiving a simple On / Off or the like on the parallel port and receiving an instruction and a trigger.

  The master (Master) switches the output from the station to the studio output or CM.

  When switching from CM to studio output, Automation is triggered by GPI and used to start the configuration after the CM.

  In this case, the switching is led by the master.

  On the other hand, it is also possible to provide a frame called “CM” in the configuration, and to switch to CM by giving a trigger in the reverse direction from the GPI to the master from the studio.

  The event executor 105E also relays between a master switcher, another software module, and the first computer device (Automation Ctrl PC) 110.

  It is necessary to ensure that the relay delay does not exceed the specified field unit. Therefore, when the operation is started at the timing of the reference signal, the GPI input is read first, and if there is a level change, it is determined what instruction is in accordance with the setting of the GPI port, and other Software module and / or the first computer device (Automation Ctrl PC) 110.

  When outputting from the GPI, the event executor 105E processes instructions received from other software modules and the first computer device (Automation Ctrl PC) 110 in units of fields. That is, when the operation is started at the timing of the reference signal, the received instructions are collected and the GPI output level is changed according to the setting of each GPI port.

  There are a plurality of processes performed by the event executor (Event Executor) 105E at the timing of the reference signal. However, the execution of each field is performed so that the delay is 1 field or less (2 fields or less from reception to transmission completion) Is essential.

  Even if the order between the processes is not strictly defined, the upper limit of the delay can be maintained.

  In FIG. 6, the database (DB) unit 101 uses, for example, Microsoft SQL Server as a data server.

  When another application rewrites the database (DB) unit 101 using the MS SQL function, the changed item is notified to the other application. This is called a dispatcher. To be precise, each application registers an item to be notified, receives a change notification, and goes to the database (DB) unit 101 for reading.

  The first image processing unit 420A includes a key processing circuit 421A and a composition circuit 422A.

  The key processing circuit 421A is connected to the key source signal selection input bus 411A and the key fill signal selection input bus 413A. The key processing circuit 421A receives the key source signal and key fill signal selected from the video signals input to the input lines L1 to L9 via the key source signal selection input bus 411A and the key fill signal selection input bus 413A. Is input. The key processing circuit 421A performs processing for generating a key signal corresponding to the control signal from the control unit 430 using the input key source signal or a built-in waveform generation circuit (wipe pattern generation circuit). The key processing circuit 421A supplies the key signal and the key fill signal to the synthesis circuit 422A.

  The synthesis circuit 422A is connected to the key processing circuit 421A, and is connected to the first background signal selection input bus 415A and the second background signal selection input bus 417A. The synthesizing circuit 422A receives a key signal and a key fill signal from the key processing circuit 421A. In addition, in the synthesis circuit 422A, the first background signal and the second background signal selected from the video signals input to the input lines L1 to L9 are the first background signal selection input bus 415A and the first background signal. 2 background signal selection input bus 417A.

  The second image processing unit 420B includes a key processing circuit 421B and a composition circuit 422B.

  The key processing circuit 421B is connected to the key source signal selection input bus 411B and the key fill signal selection input bus 413B. In the key processing circuit 421B, the key source signal and the key fill signal selected from the video signals input to the input lines L1 to L9 are transmitted through the key source signal selection input bus 411B and the key fill signal selection input bus 413B.

  The synthesis circuit 22B is connected to the key processing circuit 421B, and is connected to the first background signal selection input bus 415B and the second background signal selection input bus 417B. The synthesizing circuit 422B receives a key signal and a key fill signal from the key processing circuit 421B. In addition, the first background signal and the second background signal selected from the video signals input to the input lines L1 to L9 are input to the synthesis circuit 422B from the first background signal selection input bus 415B and the first background signal. 2 background signal selection input bus 417B. The synthesizing circuit 422B performs keying processing for synthesizing the key fill signal by replacing the area indicated by the key signal supplied from the key processing circuit 421B with the first background signal or the second background signal.

  In the above description, the key signal is binary, and it has been described that the background signal or the key fill signal is specified. More specifically, the key signal indicates density instead of binary, and the key fill signal is superimposed on the background signal. Concentration is shown in multiple values. Therefore, it is also possible to perform image processing having a portion where the key fill signal looks translucent while the background is visible.

  Further, the control unit 430 is composed of a microcomputer, generates a control signal corresponding to the selection input signal given from the selection input unit 460 via the communication path 450, and passes control lines 435A and 435B. Each operation of the matrix switcher unit 410, the first image processing unit 420A, and the second image processing unit 420B is controlled.

  The selection input unit 460 includes a microcomputer 465 to which a button arrangement unit 461, a keyboard 462, a pointing device 463 such as a mouse, a graphical display 464, and the like are connected. When the input selection is operated with the button of the button arrangement unit 461, the matrix switcher unit 410 of the main unit controls the intersection row connected to the corresponding input bus to select the input, and the corresponding image processing unit Supply video signals. Then, processing such as synthesis designated by the image processing unit is performed, and a video signal that becomes a screen including the video signal of the selected input is output. Note that when operating in a dual link system in which progressive video signals are processed in pairs, the operation is performed so that the inputs to be paired are selected on the A side and the B side, respectively. For example, when the input L1 is the link A side of the first image signal and the input L2 is the link B side of the first image signal, when the selection of the first image signal is operated with respect to the first background, The operation of selecting L1 in the first background intersection row 416A and selecting L2 in the second background intersection row 16B is performed.

  In this effect switcher device, the selection input unit 460 communicates with the control unit 430 of the main unit 440 via the communication path 450 to instruct execution of various processes.

  The synthesis circuit 422A also receives background signals from the first background signal selection input bus 415A and the second background signal selection input bus 417A, and outputs any background signal according to an instruction from the selection input unit 460. Either two background signals are synthesized by a synthesis method that is used or instructed at a designated ratio to obtain a combined background signal used for keying processing. The above ratio is manually instructed by the fader lever, etc. of the selection input unit, or in the case of automatic transition (automatic progression) operation, it changes with time and is controlled to switch from one background signal to the other background signal. Is done. The above synthesis method is, for example, as a mix, weighted addition of two background signals for each pixel at the above ratio (for example, if the ratio is 30%, a value obtained by multiplying the value of the first background signal by 0.3; The value obtained by multiplying the value of the second background signal by 0.7 is added). Alternatively, as another synthesize method, as a wipe, a process of superimposing the second background signal on the first background signal by keying using a wipe key signal supplied from a wipe key waveform generation circuit (WKG: Wipe Key Generator). Do. The key signal generated by the wipe key waveform generation circuit changes with the above ratio, and in the case of automatic transition, it is generated so as to determine the boundary line of the wipe using the time of progress as an input parameter. If it is not automatic transition, the indicated ratio is used instead of the time.

  The same applies to the synthesis circuit 422B.

  Here, an external view of the switcher 41, that is, the console 400 of the effect switcher device is shown in FIG. This is an operation portion corresponding to one of the image processing units of the main unit 440 when the dual link method is not used. In the case of the dual link method, the operation part corresponds to a pair of image processing parts.

  As shown in FIG. 10, the console 400 includes a first background button row 401, a second background button row 402, a key button row 403, a source name display row 404, transition target buttons 405A and 405B, a direction designation. Buttons 406A and 406B, a reciprocal mode designation button 407, a fader lever 408, and the like are provided.

  The first background button row 401 is operated when the first background signal selection input bus 415A selects an input line that supplies a video signal to be a background video signal to the synthesis circuit 422A.

  The second background button row 402 is operated when the second background signal selection input bus 415B selects an input line for supplying a video signal to be a background video signal to the synthesis circuit 422B.

  The key button row 403 includes an input line for supplying a video signal for which the key source signal selection input bus 411A is a key source signal to the synthesis circuit 422A, and a video signal for which the key fill signal selection input bus 413A is a key fill signal. It is operated when a combination with an input line supplied to 422A is selected.

  The source name display column 404 displays character information associated with the index number corresponding to the button number of the button arranged below in FIG. The character information is stored in the control unit 430, and the user can set the character information. The character information may be stored in association with the input line number. In that case, either of the character information associated with the first input line number corresponding to the index number corresponding to the button number of the button or the character information associated with the second input line number corresponding to the index number. Is displayed. The first input line number is a number for selecting the video signal to be the key fill signal, and the second input line number is a number for selecting the video signal to be the key source signal. The pair of the input line number and the second input line number is associated with an index number corresponding to the button number, thereby enabling the above control with the key button row. When the background button row is operated, the background video signal is selected by the first input line number. The source name display 404 normally displays character information associated with the first input line number, and is associated with the second input line number only while a separate button (not shown) is pressed. The character information may be displayed, and by doing so, the operator can confirm both character information. The association between the index number corresponding to the button number and the input line number corresponding to the index number is referred to as a cross-point button assignment.

  In the console 400, the selected button (switch) is lit.

In this program transmission control system 100, a news room control system (NRCS: News Room Computer System) block 20 acquires channel (CH) assignment information acquired from a material server such as the playout server 31. Then, the intersection sequence of the switcher 41, that is, the cross point (XPT) set in the playlist (Automation Playlist) of the Automation control block 10 is automatically selected.
That is, the channel (CH) assignment information of the playout server 31 is passed to the news room control system (NRCS) block 20 by the MOS protocol.

  The Automation control block 10 obtains channel (CH) assignment information of the playout server 31 by means such as MOS protocol roStorySend or FTP.

  Then, based on the channel (CH) assignment information, the cross point (XPT) of the switcher 41 is set / changed.

  In creating a playlist, when a video source is selected, only the playout server 31 is set and the channel (CH) is not set. That is, on the display screen of the graphical display 464, SVR is selected from the palette 464A in FIG. 11 and SVR is set in the playlist (Playlist) 464B in FIG. 12, but here the channel (CH) is not set.

  When channel (CH) information is obtained from a news room control system (NRCS: News Room Computer System) block 20, the channel (CH) information of the playout server 31 is displayed in the playlist, and the switcher ( The cross point (XPT) of Switcher) 41 is set.

  That is, in the program transmission control system 100, the Automation control block 10 mounted on the first computer device (Automation Ctrl PC) 110 executes the program transmission control program, thereby the first computer device (Automation (News Room Computer System (NRCS) block 20 mounted on the Ctrl PC) 110, the material of the material passed when the playout server (Playout Server) 31 is in a state of being output from the output channel. The playout server is referred to the appropriate bus of the switcher 41 in accordance with the selection schedule of the material in the program and the processing schedule of the switcher 41 by referring to the information and the program for program transmission. Processing for instructing selection of an input connected to the 31 output channels is performed. For example, if a certain material is to be used as a background video in a program, one of the background signal selection input buses is applicable as the appropriate bus, and the corresponding input is selected in the intersection row. Instruct them to do so. Alternatively, when keying subtitle material, the corresponding input is selected at the intersection sequence of the key source signal selection input bus and the key fill signal selection input bus, and the material is used. Alternatively, when a sub-screen is displayed by picture-in-picture, the corresponding input is selected by the key fill signal selection input bus to obtain the video signal of the material, and the key signal of only the sub-screen part is keyed by reduction etc. It is generated inside the processing circuit, and the key source signal selection input bus does not use an external video signal but forms a small screen for keying.

  Then, the output channel of the playout server 31 is controlled by the operator of the console 400 of the switcher 41, that is, the first background button row 401, the second background button row 402, the key button row 403, etc. The information of the material obtained from the first computer device (Automation Ctrl PC) 110 is displayed on the display part of the source name display column 404 at the position corresponding to the operation element for selecting the input connected to.

  The switcher 41 is provided with correspondence storage means capable of setting the correspondence between the operator of the console 400 and the input of the switcher 41 in the control unit 430, and the first controller The computer device (Automation Ctrl PC) 110 indicates the correspondence relationship for the input of the switcher 41 connected to the output channel of the playout server 31 that is scheduled to be used in the program. Is assigned to the operator of the console 400.

  Further, the information of the material is included in the instruction of the correspondence relationship, and is displayed corresponding to the operator of the console 400.

  Further, when changing the material to be output from an output channel having a material server such as the playout server 31, the clip server 43, the clip server 43, and the audio server 44, the same applies. Then, the first computer device (Automation Ctrl PC) 110 instructs the correspondence.

  Next, a specific example of program transmission in the program transmission control system 100 will be described.

  Here, the output channels CH1 and CH2 of the material server are used.

  The material clip A, clip B, and clip C to be reproduced and output from there.

  It is assumed that CH1 and CH2 are connected to input 1 and input 2 of the switcher.

  In a playlist (cue sheet), image processing by the switcher 41, that is, an effect switcher device, uses materials in the order shown in Table 1 below.

  In other words, up to two channels can be used at the same time, but three types of materials are used. The sending control computer executes the above-described playlist, but since the material server has two output channels, it is outputted in the order shown in the following Table 2.

  The control of the switcher (Switcher) 41 is instructed as input 1 and input 2, and is in the order shown in Table 3 below.

  As a result, instructions are given to the switcher 41 in the order shown in Table 4 below. In Table 4, numerals indicate input numbers.

  As automatic control, if crosspoint control (control of the matrix switcher unit) is executed as described above, a scheduled image can be output.

  Considering the possibility of switching to manual operation, it is preferable to display the material names (A, B, C) on the source name display corresponding to the crosspoint button of the console 400 of the switcher 41. .

  In order to realize this, source name information is supplied to a switcher (system including an operation console), and is associated with a material name.

  The source name information is for giving a name (character string) corresponding to each input to the switcher 41.

  Table 5 shows an example of the input of the switcher 41 and its source.

  Tables 6 and 7 show examples of setting crosspoints, buttons, and assignments. Here, it is assumed that one input line number is associated with a button number.

  For example, in the assignment of Table 6, since the input line number 1 is associated with the button number 1, according to Table 5, for example, the display corresponding to the button number 1 includes “CH1 of the material server 1”. Is displayed. For example, “relay vehicle 1” is displayed on the display corresponding to the button number 5.

  In this way, the Automation control block 10 mounted on the first computer device (Automation Ctrl PC) 110 is instructed to assign only the signal source used in the program to the button.

  Depending on the type of playout server 31, it is impossible to output different materials using the same channel in succession, so channel assignment control that takes this into consideration is necessary. In this case, for example, even a program (program) that always uses only one material is operated using two channels (CH1, CH2). For example, in the playout server, material A is output from CH1, then material B is output from CH2, subsequently material C is output from CH1, and then material A is output from CH2. It is controlled to be done. Inputs respectively connected to CH1 and CH2 are assigned (assigned) to the cross point of the switcher 41. Then, when the material is used in the progress of the program, the cross point (intersection point) is controlled so as to select the corresponding input. As a result, the material to be used at each time point is designated in the program, and the operator does not need to be aware of which channel the material is to be output from, and is correctly selected by the switcher.

  Which material is output from which channel is determined by the first computer device (Automation Ctrl PC) 110 with sufficient time to prepare for control before each switching timing. What is necessary is just to be able to acquire from an out server. It may be before the program starts or even if the program is in progress, as long as the above margin can be secured.

  Since the Automation control block 10 knows the material to be used in the playlist, the material to be used can be specified from the playlist. In addition, since the material to be used is assigned to the button, the necessary material can be selected even if it suddenly shifts to manual operation.

  Note that the console 400 of the switcher 41 is generally configured so that a double input can be selected using the “shift” button as the crosspoint button. However, since the operation on the side where the shift is pressed takes time, it is convenient that the frequently used material is assigned to a button (young number) which is not on the shift side. Therefore, even if the number of buttons is sufficient (including shift), if the input used in the program is assigned to a lower number, the operability during manual operation is improved.

  Even if the crosspoint button assignment is set by the Automation control block 10, the material name is displayed in the source name display column 404 of the console 400 of the switcher 41, so that VTR1, VTR2, etc. Including manual operation will not be hindered.

  In the program transmission control system 100 as described above, there is a circumstance that it is desired to interrupt control such as temporary news during transmission (automatic) control by the Automation control block 10 mounted on the first computer device (Automation Ctrl PC) 110. When it occurs, the operator can cancel the automatic control, and then select a desired input from the console 400 of the switcher 41 and broadcast the desired video (image). Furthermore, when it is desired to broadcast the output of the material server even in that state, the corresponding output channel of the material server is connected (and set as an operator) on the console 400 of the switcher 41. It can also be used manually by selecting the input.

The program logo, time, title, etc. are output from the material server and may be superimposed on a part of the screen by keying, so manually selecting the temporary input video signal and simultaneously keying the output of the material server The operability is improved by being able to select.
When the material server has a plurality of output channels, each is connected to the input of the switcher 41. Since the correspondence between the material output from the material server and the output channel dynamically changes depending on the program, the operator cannot know it as it is.

  However, the display mechanism of the console 400 of the switcher 41 displays the information of the material output at that time on the output channel corresponding to the operation element in characters and symbols, so that the correspondence relationship is dynamically obtained. Even in a changing situation, the operator can select a material by switching to manual operation.

  In addition to the material server, there are devices having a video output such as a conventional VTR device in the system. These are fixedly connected to the input of the switcher 41, but can be controlled from the transmission control computer according to the present invention when used simultaneously with the material from the material server.

  Also, in a program that is unlikely to use a VTR device or the like, the VTR device and the switcher remain connected, and no input corresponding to the VTR device is assigned to the operator of the console. When many are selectable by assigning to the input from the output, and the VTR device is used in another program, the assignment to the material server can be reduced to assign the operator to the input from the VTR device.

  In the above program transmission control system, the operator, that is, the crosspoint button on the panel surface, can always be manually selected, and the timing can be manually set. Also, assign to the crosspoint button and display the material name on the corresponding display for each button. The switcher 41 is a switching means and has a plurality of inputs. However, the switcher 41 does not have to be an effect switcher capable of performing keying or the like.
