Description

Signal processing equipment, switcher systems and programs

The present technology relates to a signal processing device, a switcher system, and a program that can be used, for example, as a component of a video production system.

For example, Patent Document 1 describes a vision mixer (video switcher). Conventionally, there has been a lineup of multiple vision mixers depending on the scale of video production. After the video production system is constructed, it is conceivable that a larger vision mixer will be required due to changes in the content of video production.

International Publication No. 2018/021112

The purpose of this technology is to make it possible to easily expand the scale of a vision mixer (video switcher) after constructing a video production system.

The concept of this technology is
a signal receiving unit that receives video signals from a plurality of devices having switcher signal processing functions;
a cross-point processing unit that aggregates and redistributes video signals received by the signal receiving unit to obtain video signals to the plurality of devices;
The signal processing device further includes a signal transmitter that transmits a video signal obtained by the cross-point processor to the plurality of devices.

The signal processing device according to the present technology corresponds to a crosspoint box. In the present technology, a signal receiving unit receives video signals from a plurality of devices having a switcher signal processing function. For example, the plurality of devices includes devices owned by the device itself as well as external devices.

The cross-point processing section aggregates and redistributes the video signals received by the signal receiving section to obtain video signals for multiple devices. Then, the signal transmitter transmits the video signal obtained by the cross-point processor to a plurality of devices.

For example, the signal receiving section receives a multiplexed signal in which a plurality of video signals are multiplexed on at least one transmission line from an external device, and the signal transmitting section receives a multiplexed signal in which a plurality of video signals are multiplexed from an external device on at least one transmission line. A multiplex signal in which a plurality of video signals are multiplexed may be transmitted. In this case, for example, the transmission line may be compatible with 100G QSFP. With this configuration, the number of transmission lines between external devices such as ME boxes can be reduced, the appearance of the video switcher can be simplified, and connections with external devices can be simplified. It is possible to reduce the amount of effort.

In this way, in this technology, video signals received from multiple devices with switcher signal processing functions are aggregated and redistributed to obtain video signals for multiple devices, and these video signals are sent to multiple devices. Therefore, the scale of the vision mixer (video switcher) can be easily expanded by increasing the number of devices having the signal processing function of the switcher.

In addition, other concepts of this technology are:
The switcher system has a minimum configuration including one first box having a switcher signal processing function, and can be expanded in scale by physically connecting a predetermined number of other boxes.

In the present technology, a minimum configuration includes one first box having a switcher signal processing function. The scale can be expanded by physically connecting a predetermined number of other boxes.

For example, the other predetermined number of boxes may include at least a first box that aggregates and redistributes video signals from a plurality of devices having the signal processing function of the switcher to obtain video signals to the plurality of devices. 2 box may be included. In this case, for example, the first box may be an ME box and the second box may be a crosspoint box.

For example, a predetermined number of logical switchers configured to include one or more first boxes may be provided. In this case, for example, a system manager may be provided that controls the construction of the logical switcher. Accordingly, when a plurality of first boxes are provided, it is also possible to have a plurality of small-scale logical switchers. Here, for example, a system manager may build a logical system for a physically configured system, or a system manager may build multiple logical systems within a physically configured system. It may be configured such that a system can be constructed. child

For example, the first box and the second box may be connected by a predetermined number of transmission lines, and at least one transmission line may transmit a multiplexed signal in which a plurality of video signals are multiplexed. . In this case, for example, the transmission line may be compatible with 100G QSFP. Further, in this case, for example, the second box has a signal receiving section that receives the multiplexed signal on the signal input side from the first box and performs a process of extracting individual video signals from the multiplexed signal, and A signal transmitter may be provided on the signal output side to one box for multiplexing a plurality of video signals to generate a multiplexed signal and transmitting the multiplexed signal. With this configuration, the number of transmission lines between the first box and the second box can be reduced, the appearance of the vision mixer (video switcher) can be simplified, and the number of transmission lines between the first box and the second box can be reduced. The box and the second box can be easily connected.

In this way, this technology has a minimum configuration that includes one first box with the switcher signal processing function, and can be expanded in scale by physically connecting a predetermined number of other boxes. This makes it easy to expand the scale of the vision mixer (video switcher).

In addition, other concepts of this technology are:
a procedure for detecting a predetermined number of boxes that should constitute a switcher;
configuring a predetermined number of logical switchers based on the predetermined number of boxes;
The predetermined number of boxes includes one first box having a switcher signal processing function,
or
a second box that aggregates and redistributes video signals from a plurality of devices having a signal processing function of a switcher including the first box and obtains video signals to the plurality of devices; Contains one or more boxes,
The logical switcher is configured to include one or more of the first boxes, and is included in a program for causing a computer to execute a system construction method.

This technology is a program that causes a computer to execute a system construction method. This system construction method includes a procedure for detecting a predetermined number of boxes that should constitute a switcher, and a procedure for configuring a predetermined number of logical switchers based on the predetermined number of boxes.

In this case, the predetermined number of boxes includes one first box with switcher signal processing functionality, or aggregates video signals from multiple devices with switcher signal processing functionality, including this first box. and one or more first boxes and one second box that redistributes video signals to the plurality of devices. Further, in this case, the logical switcher is configured to include one or more first boxes.

For example, the predetermined number of boxes may exist as one group or as multiple groups. In this case, for example, at least one of the plurality of groups may exist via a network. In this case, it becomes possible to configure a logical switcher by effectively utilizing a predetermined number of boxes (resources) not only as one group but as multiple groups.

In this way, in the present technology, a system construction method that includes a procedure for detecting a predetermined number of boxes that should constitute a switcher, and a procedure for configuring a predetermined number of logical switchers based on the predetermined number of boxes is implemented in a computer. This is a program to be executed, and by using this program, it is possible to easily expand the scale of the vision mixer (video switcher) by increasing the number of first boxes having the signal processing function of the switcher.

Hereinafter, modes for carrying out the invention (hereinafter referred to as "embodiments") will be described. Note that the explanation will be given in the following order.
1. Embodiment 2. Variations

<1. Embodiment>
[Switcher system configuration example]
FIG. 1 shows a configuration example of a switcher system 100. In this example, one island 101 is used.

Here, an island means a unit (group) of a predetermined number of boxes including cross point boxes, ME (Mix Effect) boxes, and the like. In this example, a predetermined number of boxes (ME box, crosspoint box) exist as one group. Further, the ME box is a box that has the signal processing functions of a switcher, such as synthesis and effect functions. Further, a crosspoint box is a box that aggregates and redistributes video signals from a plurality of devices having a switcher signal processing function such as an ME box, and obtains video signals to the plurality of devices.

The switcher system 100 includes a vision mixer 102 and a system manager 103 on one island 101. The system manager 103 is management software that defines the roles of the crosspoint boxes and ME boxes included in the island 101, and defines them as logical vision mixers (logical switchers). Here, the system manager 100 constructs a logical system for the physically configured system. The system manager 100 is configured to be able to construct a plurality of logical systems within a physically configured system.

The vision mixer 102 is constructed by the system manager 103 described above using a predetermined number of boxes included in the island 101. In this case, based on the predetermined number of boxes included in the island 101, it is possible to configure a predetermined number of logical vision mixers that each operate independently. The illustrated example shows an example in which one logical vision mixer is configured.

The switcher system 100 also includes a control panel 104, a user interface section 105, a user interface section 106, and an IP switch 107.

The control panel 104 is a switcher console for the user to operate the vision mixer 102. The user interface unit 105 is a user interface for a user to operate the system manager 103, and is configured of, for example, a PC (Personal Computer). The user interface unit 106 is a user interface for a user to operate the vision mixer 102, and is configured of, for example, a PC. The IP switch 107 transmits video/audio/metadata, etc., and performs information transmission with the outside of the switcher system. Note that in the illustrated example, audio/metadata is omitted.

The vision mixer 102 has a minimum hardware configuration including one ME box, and can be expanded in scale by physically connecting a predetermined number of other boxes. In other words, this vision mixer 102 has a stackable structure and can be mechanically expanded in size. In this case, the other predetermined number of boxes aggregates and redistributes video signals from multiple devices having switcher signal processing functions, including at least the ME box, to obtain video signals for the multiple devices. Includes 1 cross point box

FIG. 2 schematically shows that the scale of the vision mixer 102 can be mechanically expanded by increasing the number of individually configured hardware boxes. For example, the vision mixer 102 can be configured with one ME box (MR BOX).

Further, for example, the vision mixer 102 can be configured with one ME box and one cross point box (XPT BOX). As mentioned above, a crosspoint box is a box that aggregates and redistributes video signals from multiple devices with a switcher signal processing function such as an ME box, and obtains video signals to the multiple devices. In this case, there is only one ME box, so the crosspoint box in this case includes a device with the signal processing function of the switcher, and this device (internal device) and one ME box (external device) perform the switcher. A plurality of devices with signal processing functions are configured.

Furthermore, for example, the vision mixer 102 can be configured with one crosspoint box and two to four ME boxes. In this case, since there is a plurality of ME boxes, the crosspoint box in this case may or may not include a device having a switcher signal processing function.

Note that in the illustrated example, the maximum number of ME boxes is four, but the maximum number of ME boxes is not limited to four, and may be greater than that. In that case, it goes without saying that the crosspoint box is configured to be able to connect the maximum number of ME boxes.

FIG. 3(a) shows a configuration example where the vision mixer 102 is composed of one ME box (ME BOX). In this case, an input signal is sent from the IP switch 107 to one ME box, and an output signal is sent from the ME box to the IP switch 107.

FIG. 3(b) shows a configuration example where the vision mixer 102 is composed of one ME box (ME BOX) and one cross point box (XPT BOX). The display of "ME function unit included" in the crosspoint box indicates that the crosspoint box includes a device having the same function as the ME box, that is, a device having the signal processing function of a switcher.

In this case, an input signal (Input Signal) is sent from the IP switch (IP Switch) 107 to the ME box and the crosspoint box, and an output signal (Output Signal) is sent from the ME box and the crosspoint box to the IP switch 107.

Furthermore, the ME box and the crosspoint box are connected using a local line that constitutes a transmission line, and signals are transmitted (transmitted and received) between them. In this case, the transmission lines existing between the ME box and the crosspoint box include a predetermined number, usually multiple transmission lines, for transmitting signals from the ME box to the crosspoint, and a transmission line for transmitting signals from the crosspoint box to the ME box. It consists of a predetermined number of transmission lines, usually a plurality of transmission lines.

In this case, at least one transmission line transmits a multiplexed signal in which a plurality of video signals are multiplexed. For example, a transmission line compatible with 100G QSFP (quad small form factor pluggable) is used. Further, for example, this transmission line is one that can support transmission of 4K or HD video signals. By configuring to transmit multiplexed signals in this way, the number of transmission lines between the ME box and the cross-point box can be reduced, the appearance of the vision mixer 102 can be simplified, and the ME The effort required to connect the box and crosspoint box can be reduced.

In this case, the crosspoint box receives a multiplexed signal of a plurality of video signals for each transmission line from the ME block, and transmits a multiplexed signal of a plurality of video signals for each transmission line to the ME block. In this case, the crosspoint box has a signal receiving section that receives the multiplexed signal on the signal input side from the ME box and performs processing to extract individual video signals from the multiplexed signal, and has a signal receiving section on the signal output side to the ME box. , a signal transmitter that multiplexes a plurality of video signals to generate a multiplexed signal and transmits the multiplexed signal.

FIG. 4 shows a configuration example where the vision mixer 102 is composed of two ME boxes (ME BOX) and one cross point box (XPT BOX). The display of "ME function unit included" in the crosspoint box indicates that the crosspoint box includes a device having the same function as the ME box, that is, a device having the signal processing function of a switcher. Note that when the vision mixer 102 is configured with two ME boxes and one crosspoint box in this way, the crosspoint box may have a configuration that does not include a device with a switcher signal processing function. .

In addition, the ME box and the crosspoint box are connected using a local line that constitutes a transmission line, similar to the configuration example in FIG. 3(b) described above, and signals are transmitted between them. (transmission and reception) is performed.

FIG. 5 shows a configuration example where the vision mixer 102 is composed of four ME boxes (ME BOX) and one cross point box (XPT BOX). The display of "ME function unit included" in the crosspoint box indicates that the crosspoint box includes a device having the same function as the ME box, that is, a device having the signal processing function of a switcher. Note that when the vision mixer 102 is configured with four ME boxes and one crosspoint box in this way, the crosspoint box may have a configuration that does not include a device with a switcher signal processing function. .

FIG. 6 shows the input signal (Input Signal) from the IP switch 107 to each box, the output signal (Output Signal) from each box to the IP switch, and the communication between the ME box and the crosspoint box in the configuration example of FIG. 5. This shows more specifically local lines as transmission lines between the two.

The crosspoint block has a signal receiving section that receives a multiplexed signal on the signal input side from the ME box and performs processing to extract individual video signals from this multiplexed signal. In addition, the crosspoint block aggregates and redistributes video signals from the ME box (external device) and the ME function section (internal device) of this crosspoint block, and distributes the video signals to multiple devices. It has a cross point section (XPT section) that obtains the following. Furthermore, this crosspoint block has a signal processing section that multiplexes a plurality of video signals to generate a multiplexed signal and transmits the multiplexed signal to the ME box.

As described above, in the switcher system 100 shown in FIG. 1, the vision mixer (video switcher) 102 has a minimum configuration including one ME box and physically connects a predetermined number of other boxes. The scale of the vision mixer (video switcher) can be easily expanded.

Note that in the switcher system 100 shown in FIG. 1, one logical vision mixer 102 is configured based on a predetermined number of boxes included in one island 101. However, as described above, it is also possible to configure a plurality of logical vision mixers that operate independently based on a predetermined number of boxes included in one island 101.

logical vision mixers

102A and 102B are configured using them. . In this example, the vision mixer 102A is configured to include two ME boxes, and the vision mixer 102B is configured to include the remaining two ME boxes.

Note that the

vision mixers

102A and 102B may include different numbers of ME boxes to configure two vision mixers with different production scales. For example, the vision mixer 102A may be configured to include three ME boxes, and the vision mixer 102B may be configured to include the remaining one ME box. Furthermore, when four ME boxes and one crosspoint box exist in one island 101, a configuration with one to four vision mixers is possible.

In addition, although the above-described

switcher systems

100 and 100A are examples that focus on one island 101, it is also possible to perform processing by linking vision mixers each configured on a plurality of islands, or to perform processing across a plurality of islands. It is also conceivable to configure a vision mixer to perform processing.
