[0060] Embodiment 1

[0061] In order to facilitate understanding of the embodiments of the present invention, a centralized control system for an ultra-high-definition broadcast vehicle disclosed in an embodiment of the present invention is first described in detail. Figure 1As shown, the centralized control system includes: a first receiving module 10 and a first state control module 11; the first receiving module 10 is connected to the first switch and the second switch, and the first state control module 11 is respectively connected to the first display device, the second display device, multiple first cameras and multiple second cameras.

[0062] The first receiving module 10 is used to receive the first interface number of the input interface corresponding to the first video used to produce the first program signal sent by the first switching station, and receive the second interface number of the input interface corresponding to the second video used to produce the second program signal sent by the second switching station.

[0063] In a specific implementation, an interface connected to the first receiving module 10 is provided on the first switching station, and similarly, an interface connected to the first receiving module 10 is also provided on the second switching station.

[0064] The first state control module 11 is used to: send the first video usage state information to the first display device based on the first interface serial number, so that the usage state of the played video is displayed on the display window of the first display device that plays the video shot by the first camera; send the second video usage state information to the second display device based on the second interface serial number, so that the usage state of the played video is displayed on the display window of the second display device that plays the video shot by the second camera. The first state control module 11 is also used to: send the first video usage state information to multiple first cameras based on the first interface serial number, so that each first camera displays the usage state of the shot video; send the second video usage state information to multiple second cameras based on the second interface serial number, so that each second camera displays the usage state of the shot video.

[0065] Furthermore, the above-mentioned centralized control system also includes a first processing module; the first processing module is connected to the first receiving module 10 and the first state control module 11; the first processing module is used to: based on a preset first relationship set, determine a selected first camera corresponding to the first interface serial number among multiple first cameras, and determine a first selected display window corresponding to the selected first camera in the first display device; based on a preset second relationship set, determine a selected second camera corresponding to the second interface serial number among multiple second cameras, and determine a second selected display window corresponding to the selected second camera in the second display device.

[0066] Among them, the above-mentioned first relationship set stores: the correspondence between each first camera and the interface serial number of the input interface in the first switch, and the correspondence between each first camera and the display window in the first display device; the second relationship set stores: the correspondence between each second camera and the interface serial number of the input interface in the second switch, and the correspondence between each second camera and the display window in the second display device.

[0067] The first state control module 11 is used to: send the first video usage state information to the first display device, so that the usage state of the video being played is displayed as being used on the first selected display window, and the usage state of the video being played is displayed as being not used on the display window that plays the video shot by the unselected first camera; send the second video usage state information to the second display device, so that the usage state of the video being played is displayed as being used on the second selected display window, and the usage state of the video being played is displayed as being not used on the display window that plays the video shot by the unselected second camera; the first state control module 11 is also used to: send the first device state information to multiple first cameras, so that the usage state of the video being played is displayed as being used on the selected first camera, and the usage state of the video being played by the unselected first cameras other than the selected first camera is displayed as being not used; send the second device state information to multiple second cameras, so that the usage state of the video being played is displayed as being used on the selected second camera, and the usage state of the video being played by the unselected second cameras other than the selected second camera is displayed as being not used. The unselected first camera here refers to the first camera other than the selected first camera; and the unselected second camera refers to the second camera other than the selected second camera.

[0068] The input interface of the switch receives the video shot by the corresponding camera, part of the display screen of the display device plays the video content of the video shot by the corresponding camera, and another part of the display screen of the display device plays the video content of the video output by the corresponding output interface of the switch. The switch includes a first switch and a switch; the display device includes a first display device and a second display device; and the camera includes a first camera and a second camera.

[0070] Furthermore, the above-mentioned first relationship set also stores: the identification name of each first camera, the identification name of the output interface of the first switch, and the correspondence between the output interface of the first switch and the display window in the first display device; the second relationship set also stores: the identification name of each second camera, the identification name of the output interface of the second switch, and the correspondence between the output interface of the second switch and the display window in the second display device; the first state control module is also used to send the identification name of each first camera and the identification name of the output interface of the first switch to the first display device, so that each display window in the first display device displays the identification name of the source of the played video; the first state control module is also used to send the identification name of each second camera and the identification name of the output interface of the second switch to the second display device, so that each display window in the second display device displays the identification name of the source of the played video, wherein the source of the played video can be the above-mentioned camera, or it can be the output interface of the above-mentioned switch or other devices that provide video, such as a slow motion server.

[0071] The identification name may be the name of the camera, the serial number of the camera, the name of the person photographed by the camera, the shooting location of the camera, the location of the camera, etc., which may represent the source or characteristics of the video. In a specific implementation, each camera corresponds to a base station, which can transmit video signals and control the tally light of the camera to flash or go out, and the use status of the camera is determined by the flashing or going out of the tally light.

[0072] The camera can use tally lights to remind the camera operator and the people on the stage of the use of each camera. The red tally light is used to indicate which camera signal is being cut out. It helps the presenter face the camera and ensure the correct line of sight. It also reminds the camera operator that the camera signal has been cut out by the director and cannot be adjusted at will. At the same time, there will be tally indicators on the monitoring wall and camera control panel in the production area to remind the production staff and technicians which signal is currently cut out. Some tally lights will also show yellow, indicating that the camera signal has been pre-selected and will be cut in soon. When the director (the operator of the switcher) performs switching stunts such as wiping or superimposing, the red tally lights of the two cameras involved will light up at the same time. At this time, the camera operator needs to operate according to the director's intention. If you want to readjust the camera, you must wait until the tally lights go out.

[0073] Furthermore, the above-mentioned centralized control system also includes a first arrangement control module; the first arrangement control module is connected to the first display device, and the first arrangement control module is used to control the number and layout of multiple display windows in the first display device; the first arrangement control module is connected to the second display device, and the first arrangement control module is also used to control the number and layout of multiple display windows in the second display device.

[0074] In some embodiments, the first switch is an 8K switch; the first program signal is an 8K program signal; the first video is an 8K video; the first camera is an 8K camera; the second switch is a 4K switch; the second program signal is a 4K program signal; the second video is a 4K video; and the second camera is a 4K camera. The 8K or 4K here means that the resolution of the video being shot, the video being operated, or the video being included is 8K or 4K.

[0075] In some embodiments, the first switcher may be a 4K switcher, and the second switcher may be an 8K switcher. The first switcher and the second switcher may both be 8K switchers, or the first switcher and the second switcher may both be 4K switchers.

[0076] This embodiment belongs to the independent working mode. In this mode, the operations of the 4K switcher and the 8K switcher do not interfere with each other and are independent of each other. At this time, there can be two units in the centralized control system to control the 4K production system and the 8K production system respectively.

[0077] The above-mentioned ultra-high-definition broadcast vehicle uses a centralized control system. This method can control the status indicator device of the camera and the status indicator device on the multi-screen display device when multiple switchboards are working in independent mode, so as to realize dynamic source name following during video broadcasting, so that the cameraman can clearly understand which camera or cameras are being used, and the director can clearly understand which video screens are being used, so that the staff can understand the working status of each camera in time, so that the staff can adjust their work according to the working status of each camera.

Figure 3 The first switch is an 8K switch; the first camera is an 8K camera; the second switch is a 4K switch; the second camera is a 4K camera. The first program signal is an 8K program signal, the first video is an 8K video, the second program signal is a 4K program signal, and the second video is a 4K video. Figure 3 The 8K camera is also used to generate a 4K signal that is different from the 8K video only in resolution, and sends the 4K signal to the first display device 25 via the first video matrix 23 through the base station corresponding to the 8K camera. The first display device 25 is used to play the 4K signal sent by each 8K camera, and display the identification name of the 8K camera corresponding to the 4K signal under the screen playing the 4K signal. Usually, the first display device 25 includes multiple display screens, which respectively display the video content of the 4K signal sent by each base station with multiple small screens, and display the video content of the 8K program signal with a larger screen, and each display screen needs to display which camera the source of the screen is (that is, the identification name of the display camera).

[0096] Specifically, 8K videos shot by multiple 8K cameras are sent to the corresponding base stations. Each 8K camera also generates a 4K signal, which is also sent to the corresponding base station. The base station sends the 8K video to the 8K switcher.

The first down-conversion device is used to receive the 8K main program sent by the 8K switcher, down-convert the 8K main program to obtain a first down-conversion signal, and send the first down-conversion signal to the first display device 25 via the first video matrix 23, so that the first display device 25 uses a larger display screen to display the first conversion signal and the identification name of the output interface of the 8K switcher corresponding to the first conversion signal, which is generally PGM.

[0099] The above-mentioned second down-conversion device is used to receive the 8K preview signal sent by the 8K switcher, down-convert the 8K preview signal to obtain a second down-conversion signal, and send the second down-conversion signal to the first display device 25 via the first video matrix 23, so that the first display device 25 uses a larger display screen to display the second conversion signal and the identification name of the output interface of the 8K switcher corresponding to the second conversion signal, which is generally PVW.

[0101] like Figure 4 FIG. 1 is a schematic diagram of a display device provided by an embodiment of the present invention. Figure 4 The PGM in it indicates the identification name of the program interface, the PVW indicates the identification name of the pre-cut interface, and the "name" indicates the identification name of the camera corresponding to the video played on each screen or the identification name of the output section of the switcher. Figure 4 Window status prompting device 100 is shown in FIG. 1 , and is exemplarily shown in the form of a tally light.

[0102] Specifically, the PGM signal is the video signal being broadcast after being produced by the switcher, and the PVW signal is the pre-selected video signal that may be broadcast soon but has not yet been broadcast.

[0103] The above-mentioned ultra-high-definition broadcast vehicle can enable the cameraman and director to clearly know which camera is being used during video broadcasting, so that the staff can understand the working status of each camera in a timely manner.

[0113] The second state control module 51 is used to send video usage status information to the second display device, so that the usage status of the video being played is displayed as being used on the selected display window, and the usage status of the video being played is displayed as being not being used on the display window that plays the video shot by the unselected camera. The second state control module 51 is also used to send device status information to multiple cameras, so that the usage status of the video shot by the selected camera is displayed as being used, and the usage status of the video shot by the unselected cameras is displayed as being not being used. The unselected cameras here refer to cameras other than the selected camera.

[0128] In a specific implementation, each camera is provided with a machine status prompting device, and each machine status prompting device is used to display the current usage status of the video shot by the camera where the machine status prompting device is located.

[0129] In actual applications, the first display device 25 includes multiple first window status prompt devices, each display window is provided with a first window status prompt device, and each first window status prompt device is used to display the usage status of the video played in the display window; the second display device 26 also includes multiple second window status prompt devices, each display window is provided with a second window status prompt device, and each second window status prompt device is used to display the usage status of the video played in the display window.

[0130] The first switcher and the second switcher of this embodiment can be the same or different. When the first switcher and the second switcher are the same, the output videos can be backed up mutually. When the first switcher and the second switcher are different, two native videos with different resolutions can be generated to meet the use requirements. The following description takes the first switcher as an 8K switcher and the second switcher as a 4K switcher as an example.

[0131] Figure 7 Another ultra-high-definition OB truck is given. Figure 7 The first switch is an 8K switch; the first camera is an 8K camera; the second switch is a 4K switch; the second camera is a 4K camera. The first program signal is an 8K program signal, the first video is an 8K video, the second program signal is a 4K program signal, and the second video is a 4K video. Figure 7The ultra-high-definition OB vehicle in the system works in the follow-up working mode. Compared with the independent working mode, the follow-up working mode also includes an up-conversion device. The 8K switcher is provided with a linkage interface. Each 8K camera outputs 8K video and 4K video with the same content but different resolutions. The 4K video enters the 4K switcher for production. On the one hand, the output 4K program signal enters the second video matrix and is output to the receiver. On the other hand, it is converted into an 8K conversion signal through the up-conversion device and input into the 8K switcher via the linkage interface. The 8K switcher produces the 8K video sent by the 8K camera and the 8K conversion signal sent by the 4K switcher based on the operation of the 4K switcher, and outputs the 8K program signal. There is no director to operate at the 8K switcher, and the follow-up production is carried out following the operation of the 4K switcher.

[0132] The following is a detailed introduction to the follow-up working mode;

[0133] N 8K cameras output N 8K video signals, which are sent by the base station to the first N input channels of the 8K switcher. N native 4K videos are sent via the base station to the first N input interfaces of the 4K switcher. At the same time, the interface order of the 8K video of the 8K camera entering the 4K switcher is consistent with the interface order of its corresponding 8K video signal entering the 8K switcher.

[0134] In addition, the M channels of 4K videos output by the M 4K cameras are sent by the base station to other available idle interfaces of the 4K switcher. The 4K switcher can operate all 4K videos, and the output 4K program signals are sent to the up-conversion device for up-conversion, converted into 8K conversion signals and sent to the N+1th interface (which is a linkage interface or connected to a linkage interface) of the 8K switcher.

[0135] If the 4K switcher only operates the first N video signals, the 8K switcher will perform the same operations as the 4K switcher on the 8K video transmitted by the same interface number as the 4K switcher to generate 8K program signals. If the signal source operated by the 4K switcher includes the input signal of the M 4K cameras at the back, the signal received by the linkage interface is directly output on the 8K switcher as the 8K program signal. There is no director to operate at the 8K switcher, and the above corresponding operations are performed only according to the operations of the 4K switcher.

[0136] Usually, 8K program signals include 8KPGM signals and 8KPVW signals. For example, the 8KPGM signal is produced by the 8K video sent by 8K camera 1 and 8K camera 2, and the 8KPVW signal is produced by the 8K video sent by the 8K camera; the 4K switcher sends the corresponding interface serial number to the centralized control system. The centralized control system finds the corresponding camera serial number and the display window corresponding to the camera based on the interface serial number, and then sends a control signal to the first display device so that the window status prompt device on the corresponding display screen prompts (for example, the red tally light on the display window that plays the video shot by 8K camera 1 and the video shot by 8K camera 2 is on, and the yellow tally light on the display window that plays the video shot by the 8K camera is on). The centralized control system sends the control signal to the base station, and the base station controls the tally light on the camera so that the camera being used and the camera to be used are displayed (for example, the red tally light on the above-mentioned 8K camera 1 and 8K camera 2 is on, and the yellow tally light on the 8K camera is on).

[0137] The above-mentioned ultra-high-definition OB vehicle displays the name of the video source on the display device, so that the staff in the OB vehicle can understand the source of the played video and realize dynamic source name following; at the same time, the tally light on the camera prompts the stage staff the usage status of each camera, so that the staff can understand the working status of a camera.

The third state control module 81 is also used to send device status information to multiple first cameras and multiple second cameras based on the fourth interface serial number and the fifth interface serial number, so that each first camera and each second camera displays the usage status of the shot video.

[0142] In actual applications, the above-mentioned centralized control system also includes a third processing module; the third processing module is connected to the third receiving module and the third state control module; the third processing module is used to: based on the fourth interface serial number, the fifth interface serial number and the preset fourth relationship set, determine the selected camera corresponding to the fourth interface serial number, and determine the selected display window corresponding to the selected camera in the display device, wherein the fourth relationship set stores: the correspondence between each first camera and the interface serial number of the input interface in the first switching station, the correspondence between each second camera and the interface serial number of the input interface in the second switching station, and the correspondence between the output interface of the second switching station and the interface serial number of the input interface of the first switching station, the correspondence between each first camera and the display window in the display device, and the correspondence between the second camera and the display window in the display device.

[0143] The third state control module 81 is used to: send video usage state information to the display device, so that the selected display window displays the usage state of the played video as being used, and the display window that plays the video shot by the unselected camera displays the usage state of the played video as being not used; and send device state information to the plurality of first cameras and the plurality of second cameras, so that the selected camera displays the usage state of the shot video as being used, and the unselected cameras other than the selected camera display the usage state of the shot video as being not used. The unselected cameras here refer to the cameras other than the selected camera.

[0144] The input interface of the switch receives the video shot by the corresponding camera, part of the display screen of the display device plays the video content of the video shot by the corresponding camera, and another part of the display screen of the display device plays the video content of the video output by the corresponding output interface of the switch. The switch includes a first switch and a switch; the display device includes a first display device and a second display device; and the camera includes a first camera and a second camera.

[0145] In a specific implementation, the above-mentioned first video program is determined as follows: for each second camera among multiple second cameras, the second video generated by the current second camera is sent to the second switching station through the base station corresponding to the current second camera, so that the second switching station receives multiple second videos; through the second switching station, at least one second video is selected from the multiple second videos received for live production to obtain the first video program; the first video program is sent to the extension interface of the first switching station; wherein the extension interface is the input interface of the first switching station.

[0146] The above-mentioned first program signal is determined in the following manner: for each first camera among multiple first cameras, the first video generated by the current first camera is sent to the first switching station through the base station corresponding to the current first camera, so that the first switching station receives multiple channels of first videos; through the first switching station, the received multiple channels of first videos and\or first video programs are produced on-site to obtain the first program signal.

[0147] In actual applications, the above-mentioned third processing module is also used for: if the fourth interface serial number does not include the interface serial number corresponding to the extended interface, then the first camera corresponding to the fourth interface serial number is determined from the fourth relationship set as the selected camera; if the fourth interface serial number only includes the interface serial number corresponding to the extended interface, then the second camera corresponding to the fifth interface serial number is determined from the fourth relationship set as the selected camera; if the fourth interface serial number includes the interface serial number corresponding to the extended interface, and the interface serial number other than the interface serial number corresponding to the extended interface, then the first camera corresponding to the fourth interface serial number and the second camera corresponding to the fifth interface serial number are determined from the fourth relationship set as the selected cameras.

[0148] In some embodiments, the fourth relationship set also stores: the identification name of each first camera, the identification name of the output interface of the first switch, and the correspondence between the output interface of the first switch and the display window in the display device; the third state control module is also used to send the identification name of each first camera, the identification name of each second camera and the identification name of the output interface of the first switch to the display device, so that each display window in the display device displays the identification name of the source of the video being played.

[0149] Furthermore, the above-mentioned centralized control system also includes a third arrangement control module; the first arrangement control module is connected to the first display device, and the third arrangement control module is used to control the number and layout of multiple display windows in the first display device; the third arrangement control module is connected to the second display device, and the third arrangement control module is also used to control the number and layout of multiple display windows in the second display device.

[0150] In some embodiments, the first switch is an 8K switch; the first program signal is an 8K program signal; the first video is an 8K video; the first camera is an 8K camera; the second switch is a 4K switch; the second program signal is a 4K program signal; the second video is a 4K video; and the second camera is a 4K camera.

[0151] In some embodiments, the first switcher may be a 4K switcher, and the second switcher may be an 8K switcher. The first switcher and the second switcher may both be 8K switchers, or the first switcher and the second switcher may both be 4K switchers.

[0152] This embodiment belongs to the extended working mode. In this mode, the 4K switcher and the 8K switcher need to cooperate with each other. At this time, the centralized control system can be provided with two units, 4K unit and 8K unit, to respectively receive the interface serial numbers sent by the above 4K switcher and 8K switcher and match them from the preset relationship set. The 4K module and the 8K module cooperate with each other to centrally control the entire OB vehicle.

After receiving the interface serial number sent by the 4K switcher and the 8K switcher, the centralized control system searches for the camera identification name corresponding to the interface serial number through the interface serial number, and sends a control signal to the display device and the base station, so that the identification name of the corresponding camera is displayed on the screen of the program signal played in the display device, and the indicator light on the corresponding camera lights up, so that the staff can understand the working status of each camera in time.

[0154] Embodiment 6

[0155] Corresponding to the centralized control system provided in the fifth embodiment, the embodiment of the present invention also provides another ultra-high-definition broadcast vehicle, such as Fig. 9 As shown, the OB vehicle includes a centralized control system 20 , a second switching station 22 connected to the centralized control system 20 , a first switching station 21 , a first video matrix 23 and a display device 90 .

[0156] The above-mentioned second switching station 22 is used for: receiving multiple channels of first videos sent by multiple second cameras through the base station, selecting at least one channel of the first video from the multiple channels of first videos for live production to obtain a first video program; sending the first video program to the extended interface of the first switching station; and sending the fourth interface serial number of the input interface corresponding to the first video used to produce the first video program to the centralized control system 20.

[0157] The above-mentioned first switching station 21 is used to: receive the first video and the first video program sent by multiple second cameras through the base station, and perform on-site production of the received multiple channels of first videos and / or first video programs to obtain a first program signal; and send the fifth interface serial number corresponding to the signal used to produce the first program signal to the centralized control system 20.

[0159] The above-mentioned display device 90 is used to: play the video content of the first program signal, the video content shot by each first camera, and the video content shot by each second camera; and based on the video usage status information, display the usage status of the played video on the display window that plays the videos shot by multiple first cameras and the videos shot by multiple second cameras.

[0160] Further, the above-mentioned centralized control system includes a third receiving module, a third processing module and a third state control module connected in sequence; the third receiving module is used to receive a fourth interface serial number and a fifth interface serial number; the third processing module is used to determine the selected camera corresponding to the fourth interface serial number and the selected display window corresponding to the selected camera in the display device based on the fourth interface serial number, the fifth interface serial number and a preset fourth relationship set; wherein the fourth relationship set stores: the corresponding relationship between each first camera and the interface serial number of the input interface in the first switching station, the corresponding relationship between each second camera and the interface serial number of the input interface in the second switching station, the corresponding relationship between the output interface of the second switching station and the interface serial number of the input interface of the first switching station, the corresponding relationship between each first camera and the display window in the display device, and the corresponding relationship between the second camera and the display window in the display device;

[0161] The above-mentioned third state control module is used to: send video usage status information to the display device, so that the usage status of the played video is displayed as in use on the selected display window, and the usage status of the played video is displayed as not in use on the display window that plays the video shot by the unselected camera; the third state control module is also used to: send device status information to multiple first cameras and multiple second cameras, so that the usage status of the shot video is displayed as in use on the selected camera, and the usage status of the shot video displayed by the unselected cameras other than the selected camera is not in use.

[0162] In some embodiments, the first switch is an 8K switch; the first program signal is an 8K program signal; the first video is an 8K video; the first camera is an 8K camera; the second switch is a 4K switch; the second program signal is a 4K program signal; the second video is a 4K video; and the second camera is a 4K camera. The 4K switch can be used to: receive M channels of 8K videos sent by multiple second 8K cameras through a base station in the form of 4M channels of 4K signals, and perform live production from at least one 8K video among the M channels of 8K videos to obtain an 8K video program; send the 8K video program to the extended interface of the 8K switch; send the interface serial number of the input interface corresponding to the 8K video used to produce the 8K video program to the centralized control system 20; wherein, each 4 processing interfaces in the 4K switch are bound as a group of interfaces for processing and output, and the processing interface of the 4K switch includes an input interface and an output interface.

[0163] The above-mentioned 8K switcher is also used to: receive 8K videos sent by multiple second 8K cameras through the base station and receive 8K video programs, and perform on-site production of the received multiple 8K videos and / or 8K video programs to obtain 8K program signals; and send the interface serial number corresponding to the signal used to produce the 8K program signal to the centralized control system 20.

[0164] Fig.10 The OB vehicle shown is operating in extended operation mode. Fig.10 The 8K videos shot by multiple 8K cameras are sent to the corresponding base stations. Each 8K camera also generates 4K videos, which are also sent to the corresponding base stations. Some base stations send multiple 8K videos to 4K switchers respectively, while other base stations send multiple 8K videos to 8K switchers. Since 4K switchers can only operate 4K signals, the 8K videos sent to the 4K switchers are 4-channel 4K signals bound together as a group. Each group of 4-channel 4K signals is synchronously input, output and produced in the 4K switcher. That is, the 4K switcher receives 4-channel 4K signals bound as a group of 8K videos for processing and outputs the processed 8K videos. The processed 8K videos are also a group of 4-channel bound 4K signals. The processed 8K video is input to the 8K switcher through its expansion interface. The 8K switcher receives the 8K video sent by the 8K camera and the 8K video processed by the 4K switcher for processing, and outputs the produced 8K PGM signal and PVW signal (equivalent to the 8K program signal). The 8K PGM signal and PVW signal are down-converted into 4K video signals and sent to the first display device through the first video matrix.

[0165] The following example illustrates the extended working mode:

[0166] The 8K switcher has N interfaces, including one expansion interface. The 4K switcher has 4M interfaces, which are bound into M groups. The 4K switcher can process M 8K video signals and input the produced 8K video to the 8K switcher through the expansion interface. The 8K switcher can also receive N-1 8K video signals for processing. That is, this solution expands the 8K video production capability by binding the 4-channel interfaces of the 4k switcher.

[0167] The centralized control system in the above-mentioned ultra-high-definition OB van works in the extended working mode. After receiving the interface serial number sent by the 4K switcher and the 8K switcher, the centralized control system searches for the identification name of the camera corresponding to the interface serial number through the interface serial number, and sends a control signal to the display device and the base station, so that the identification name of the corresponding camera is displayed on the screen of the program signal played in the display device, and the indicator light on the corresponding camera lights up. This allows the staff to understand the working status of each camera in a timely manner.

[0168] A summary of the above working modes:

[0169] Some 8K switchers are compatible with baseband signals (also called SDI signals) and IP signals, but some can only process IP signals. Therefore, for devices other than the 8K switcher 21, when sending the video of the SDI signal to the 8K switcher 21, it needs to be converted into an IP signal through a format converter (IPG for short). The IP signal output by the 8K switcher needs to be converted into an SDI signal through a format converter before it can be processed and transmitted to the down-conversion device, video matrix and other devices. In addition, when transmitting IP signals, they are generally transferred through an optical switch, that is, the signals input to the 8K switcher are all transmitted through the optical switch, and the signals output by the 8K switcher are also transmitted by the optical switch.

[0170] The 8K switcher includes a system management device, which controls each interface of the 8K switcher to obtain the video sent by the preset camera. In addition, the system management device is also connected to the centralized control system 20, and sends the correspondence between the interface serial number of the 8K switcher and the serial number of the 8K camera to the centralized control system 20. The 8K switcher and the 4K switcher are connected to the centralized control system through the control server in the switcher, and the control server sends the interface serial number to the centralized control system. Among them, the control server of the 4K switcher is generally connected to the centralized control system through the I / O interface, and the control server of the 8K switcher is generally connected to the centralized control system through Ethernet.

[0171] The 4K signal is an SDI signal. The video signals input to the 8K switcher are all 8K signals in IP format. The video signals output by the 8K switcher are also 8K signals in IP format. The format converter receives the 8K signal in IP format and converts it into a set of 4-channel 4K signals in SDI format. A set of 4-channel 4K signals in SDI format is one 8K video signal.

[0172] Therefore, when the 8K switcher can only process IP signals, the structural diagram is as follows Fig.11 Generally speaking, SDI signals are transmitted through a video matrix, and IP signals are transmitted through an optical switch. Both the video matrix and the optical switch are connected to a centralized control system so that the centralized control system can obtain the corresponding relationship between the input and output signals of the video matrix and the optical switch.

[0173] In specific implementation, 8K cameras can generally output 8K video in IP format, 8K video in SDI format, 4K video in SDI format and high-definition (HD) video signals in SDI format, which are sent to a receiver through a base station.

[0174] The present invention can display the name of the video source on a display device, so that the staff in the OB vehicle can understand the source of the played video and realize dynamic source name following; the tally light on the camera can also prompt the stage staff the use status of each camera; at the same time, the present invention supports centralized control in multiple working modes and supports centralized control in different signal formats.
