Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0048] Based on the problems mentioned in the background, the embodiments of the present application provide a super high-definition truck centralized control method, which can be applied to the video relay centralized control scene of the truck. In order to facilitate the understanding of the embodiments of the present application, first, a super high-definition truck centralized control method disclosed by the embodiments of the present application is introduced in detail, which is applied to the centralized control system in the truck.

[0049] It should be noted that the first switching table in the embodiments of the present application is taken as an example of an 8K switching table, and the second switching table is taken as an example of a 4K switching table for detailed description, but it is not limited thereto (for example, in some embodiments, the first switching table can also be a 4K switching table, and the second switching table can also be an 8K switching table, the first switching table and the second switching table can also be the same switching table, such as 8K switching table, 4K switching table or other switching table).

[0050] The following input device can be a camera, a video recorder or a slow motion server, etc. which will send a video signal to the switching table. When the input device is a camera, the video captured by the camera needs to be output through the camera base station, and the signal sent to the camera is received through the camera base station, that is, the camera sends or receives the signal through the camera base station.

[0051] Embodiment one

[0052] As Figure 1 The super high-definition truck centralized control method corresponding to the 8K system in the independent working mode is shown in the figure, which includes the following steps:

[0053] Step S102, receiving the first channel serial number sent by the 8K switching table; wherein the first channel serial number includes the channel serial number of the input channel corresponding to the 8K input signal used by the 8K switching table to produce the 8K production program.

[0054] In a specific implementation, the 8K switcher arranged on the 8K broadcast vehicle can receive the 8K input signals sent by the 8K input devices, and which input channel of the 8K switcher each 8K input device inputs into is set in advance, that is, the 8K input devices and the input channels of the 8K switcher have a one-to-one correspondence. Each input channel included in the 8K switcher has a unique channel number.

[0055] Specifically, the 8K production program is obtained through the following steps 10-11.

[0056] Step 10, for each 8K input device of the preset plurality of 8K input devices, send the 8K input signal generated by the current 8K input device to the 8K switcher, so that the 8K switcher receives multiple 8K input signals.

[0057] The 8K input device can be an 8K camera or an 8K recorder or the like device capable of generating an 8K video signal; meanwhile, each 8K camera corresponds to a camera base station.

[0058] Step 11, select at least one 8K input signal from the received multiple 8K input signals through the 8K switcher to perform live production, and obtain an 8K production program. The 8K switcher can also send the 8K production program to the first multi-picture monitoring device, or send the 8K production program after further processing to the first multi-picture monitoring device.

[0059] In a specific implementation, for each 8K input device of the plurality of 8K input devices, the 4K video signal (which can also be replaced by a high-definition video signal, that is, the 8K input device can also generate a high-definition video signal) generated by the current 8K input device can be sent to the first multi-picture monitoring device via the first matrix system; wherein the 8K input signal and the 4K video signal generated by the 8K input device are only different in resolution; and then the 4K video signal sent by each 8K input device and the identification of the 8K input device corresponding to each 4K video signal are displayed through the first multi-picture monitoring device.

[0060] It should be noted that the 8K switcher is also the first switcher; the 8K production program is the first production program; the 8K input signal is the first input signal received by the first switcher; the 8K input device is the first input device that sends signals to the first switcher, and the 8K input device includes an 8K camera.

[0061] In some embodiments, the first production program includes a first program signal and a first pre-monitor signal; the first multi-picture monitoring device includes a plurality of monitoring pictures; the video content of the first program signal and the identification of the first input device corresponding to the first program signal are displayed on a first monitoring picture in the first multi-picture monitoring device; and the video content of the first pre-monitor signal and the identification of the first input device corresponding to the first pre-monitor signal are displayed on a second monitoring picture in the first multi-picture monitoring device. The first monitoring picture and the second monitoring picture are different monitoring pictures in the first multi-picture monitoring device.

[0062] In step S104, the selected 8K input device corresponding to the first channel number is determined from the preset relationship data set, and a first selected monitoring picture in the first multi-picture monitoring device corresponding to the selected 8K input device is determined.

[0063] In a specific implementation, the relationship data set includes: a correspondence between each 8K input device and a channel number of an input channel in the 8K switcher (i.e., which channel number of the 8K switcher corresponds to the input channel into which the 8K input signal output by each 8K input device is input); and a correspondence between each 8K input device and a monitoring picture in the first multi-picture monitoring device (i.e., which picture in the first multi-picture monitoring device plays the output signal of the 8K switcher).

[0064] In some embodiments, the relationship data set further includes: an identification of each 8K input device, an identification of an output channel of the 8K switcher, and a correspondence between the output channel of the 8K switcher and a monitoring picture in the first multi-picture monitoring device. The central control system can further send the identification of each 8K input device and the identification of the output channel of the 8K switcher to the first multi-picture monitoring device, so that each monitoring picture in the first multi-picture monitoring device displays the identification of the source of the played video.

[0065] In step S106, a first picture control signal is sent to the first multi-picture monitoring device, so that the first selected monitoring picture displays the use state of the video played in the first selected monitoring picture as used.

[0066] In a specific implementation, the use state displayed on the unselected monitoring picture in the first multi-picture monitoring device is unused. The unselected monitoring picture plays the video content of the video generated by the unselected input device.

[0067] In step S108, a first device control signal is sent to the plurality of 8K input devices, so that the use state of the video played on the selected 8K input device is used.

[0068] In a specific implementation, the use state displayed on the unselected input device in the plurality of 8K input devices is unused.

[0069] In some embodiments, the above-mentioned 8K input device can be an 8K camera, at this time, the use of each camera can be prompted to the camera operator and the personnel on the stage through the form of tally indicator light on the camera. The red tally light is used to indicate which camera signal is being cut out, which helps the on-air talent to face the lens, ensures the correct line of sight, and reminds the camera operator that the camera signal has been cut out by the director, at which time it cannot be adjusted at will. At the same time, there will also be a tally indication on the monitoring wall in the production area and the camera control panel, prompting the production personnel and technicians which signal is currently cut out. Some tally lights will also display yellow, prompting that the camera signal has been preselected and may be cut out soon. When the director (operator of the switcher) performs switching tricks such as keying or overlaying, the tally red lights of the two cameras involved will be lit at the same time, at which time the camera operator needs to operate according to the director's intention, and if the camera needs to be adjusted again, it must wait until the tally light is extinguished.

[0070] In a specific implementation, the first production program can be an 8K production program, which includes an 8K program signal (equivalent to the above-mentioned first program signal) and an 8K preview signal (equivalent to the above-mentioned first preview signal), and the output channel of the 8K switcher includes a first program channel and a first preview channel; the first selected monitoring picture includes a first program picture and a first preview picture; the first program channel is used to output the 8K program signal to the first multi-picture monitoring device, so that the video content of the 8K program signal is played on the main program picture of the first multi-picture monitoring device; and the first preview channel is used to output the 8K preview signal to the first multi-picture monitoring device, so that the video content of the 8K preview signal is displayed on the main preview picture of the first multi-picture monitoring device.

[0071] Based on the above description, the above-mentioned step S106 can be implemented by the following steps: sending a first picture control signal to the first multi-picture monitoring device, so that the use state of the played video displayed on the 8K program picture is used as the main output, and the use state of the played video displayed on the first preview picture is used as the preview cut.

[0074] The multi-picture monitoring device displays the video content of the video signal, which is generally displayed at a 4K resolution or a high definition resolution. Therefore, when the video signal with a resolution of 8K is monitored by the multi-picture monitoring device, the video signal with a resolution of 8K is generally converted into a video signal with a resolution of 4K or a video signal with a resolution of high definition by a down converter on the truck, so as to realize the video after shooting or production by the multi-picture monitoring device.

Each picture in the first multi-picture monitoring device needs to monitor the source of the picture, that is, display the identification of the camera or the identification of the output channel of the switcher.

[0077] For example, the PGM signal is made by the 8K input signal transmitted by the first channel and the second channel in the 8K switcher, and the PVW signal is made by the 8K input signal transmitted by the third channel in the 8K switcher. The first 8K camera, the second 8K camera and the third 8K camera respectively send the shot 8K input signal to the first channel, the second channel and the third channel. The control system receives the serial number of the first channel and the second channel corresponding to the PGM signal, and the serial number of the third channel corresponding to the PVW signal, and the number of the corresponding 8K camera is the first 8K camera, the second 8K camera and the third 8K camera, and the identification of the first 8K camera, the second 8K camera and the third 8K camera is obtained, and the control signal is sent to the first multi-picture monitoring device, so that the identification of the first program channel of the 8K switcher is displayed as "PGM" on the main program picture playing the PGM signal, the identification of the first pre-cut channel of the 8K switcher is displayed as "PVW" on the main pre-monitoring picture playing the PVW signal, the video content shot by each camera is played and the identification of the corresponding camera is displayed, the played video is displayed as the main output (such as the red indicator light on) on the monitoring picture of the first 8K camera and the monitoring picture of the second 8K camera, the played video is displayed as the pre-cut (such as the yellow indicator light on) on the monitoring picture of the third 8K camera, and the played video is not used on the other monitoring pictures.

[0078] As Figure 4 Fig. 4 shows a method for centralized control of an ultra-high-definition mobile broadcasting vehicle in an independent working mode, and the method comprises the following steps:

[0079] In step S402, a second channel number sent by the 4K switcher is received, wherein the second channel number comprises a channel number of an input channel corresponding to a 4K input signal used by the 4K switcher to produce a 4K production program.

[0080] In a specific implementation, the 4K switcher arranged on the ultra-high-definition mobile broadcasting vehicle can receive a 4K input signal sent by a 4K input device, and each 4K input device is arranged in an input channel of the 4K switcher in advance, that is, the 4K input device and the input channel of the 4K switcher have a one-to-one correspondence. Each input channel of the 4K switcher has a unique channel number.

[0081] It should be noted that the 4K switcher is a second switcher, the 4K production program is a second production program, the 4K input signal is a second input signal, and the 4K input device is a second input device, which comprises a 4K camera.

[0082] Specifically, the 4K production program is obtained through the following steps 20-21.

[0083] In step 20, for each 4K input device of a plurality of preset 4K input devices, a 4K input signal generated by the current 4K input device is sent to the 4K switcher, so that the 4K switcher receives a plurality of 4K input signals.

[0084] The 4K input device can be a 4K camera or a 4K recorder, etc., which can generate a 4K video signal, and each 4K camera corresponds to a camera base station.

[0085] In step 21, at least one 4K input signal is selected from the received plurality of 4K input signals by the 4K switcher to produce a live production, thereby obtaining the 4K production program. The 4K switcher can also send the 4K production program to the second multi-picture monitoring device.

[0086] In a specific implementation, for each 4K input device of the plurality of 4K input devices, the 4K input signal generated by the current 4K input device can also be sent to the second multi-picture monitoring device via the second matrix system, and the 4K input signal sent by each 4K input device and the identification of the 4K input device corresponding to each 4K input signal are displayed by the second multi-picture monitoring device. The identification of the 4K input device can be the name of each 4K input device, the number of the 4K input device, the position of the 4K input device, or the person photographed by the 4K input device, etc.

[0087] Step S404, determining the selected 4K input device corresponding to the second channel number from the preset relationship data set, and determining the second selected monitoring picture in the second multi-picture monitoring device corresponding to the selected 4K input device.

[0088] In the relationship data set, the corresponding relationship between each 4K input device and the channel number of the input channel in the 4K switcher (i.e., which channel number of the 4K switcher corresponds to the input channel into which the 4K input signal output by each 4K input device is input) and the corresponding relationship between each 4K input device and the monitoring picture in the second multi-picture monitoring device (i.e., which picture in the second multi-picture monitoring device plays the output signal of the 4K switcher) are included.

[0089] In some embodiments, the relationship data set further includes the identification of each 4K input device, the identification of the output channel of the 4K switcher, and the corresponding relationship between the output channel of the 4K switcher and the monitoring picture in the second multi-picture monitoring device. The central control system can also send the identification of each 4K input device and the identification of the output channel of the 4K switcher to the second multi-picture monitoring device, so that each monitoring picture in the second multi-picture monitoring device displays the identification of the played video source.

[0090] Step S406, sending a second picture control signal to the second multi-picture monitoring device to make the second selected monitoring picture display the use state of the played video in the second selected monitoring picture as used.

[0091] In a specific implementation, the use state displayed on the unselected monitoring picture in the second multi-picture monitoring device is not used.

[0092] Step S408, sending a second device control signal to the multi-4K input device to make the selected 4K input device display the use state of the generated video as used.

[0093] In a specific implementation, the use state displayed on the unselected input device in the multi-4K input device is not used.

[0094] In some embodiments, the second production program (equivalent to the 4K production program) includes a second program signal and a second pre-monitoring signal; the output channel of the 4K switcher includes a second program channel and a second pre-cut channel; the second selected monitoring picture includes a second program picture and a second pre-monitoring picture; the second program channel is used to output the second program signal to the second multi-picture monitoring device, so that the video content of the second program signal is played on the main program picture of the second multi-picture monitoring device; and the second pre-cut channel is used to output the second pre-monitoring signal to the second multi-picture monitoring device, so that the video content of the second pre-monitoring signal is displayed on the main pre-monitoring picture of the second multi-picture monitoring device.

[0095] In specific implementation, the aforementioned second produced program can be a 4K produced program, which includes a 4K program signal (equivalent to the aforementioned second program signal) and a 4K preview signal (equivalent to the aforementioned second preview signal). The second multi-screen monitoring device includes multiple monitoring screens. After obtaining the 4K produced program, the 4K program signal and the 4K preview signal can be sent to the second multi-screen monitoring device through the second matrix system, so that the second multi-screen monitoring device can use a larger monitoring screen to display the 4K program signal and the identifier of the corresponding 4K input device, as well as the 4K preview signal and the identifier of the corresponding 4K input device. The structure of the second multi-screen monitoring device can be referenced from [reference needed]. Figure 2 .

[0096] Based on the above description, step S406 can be implemented by the following steps: sending a second screen control signal to the second multi-screen monitoring device so that the usage status of the video being played on the 4K program screen is set as main output, and the usage status of the video being played on the second preview screen is set as pre-cut.

[0097] The selected 4K input devices include program 4K input devices and pre-cut 4K input devices; the input video of the program 4K input devices is used to create 4K program signals; the input video of the pre-cut 4K input devices is used to create 4K preview signals; the above step S208 can be implemented by sending a second device control signal to multiple 4K input devices, so that the program 4K input devices display the usage status of the generated video as being used as the main output, and the pre-cut 4K input devices display the usage status of the generated video as being used as pre-cut.

[0098] In some embodiments, the centralized control system also sends the identifier of each 4K input device to the second multi-screen monitoring device so that the corresponding 4K input device identifier is displayed on the monitoring screen playing the video generated by the 4K input device; sends the identifier of the second program channel to the second multi-screen monitoring device so that the main program screen of the second multi-screen monitoring device also displays the identifier of the second program channel; and sends the identifier of the second pre-cut channel to the second multi-screen monitoring device so that the main pre-screen screen of the second multi-screen monitoring device also displays the identifier of the second pre-cut channel.

[0099] To facilitate understanding of the embodiments of the present invention, an 8K input device is used as an 8K camera and a 4K input device is used as a 4K camera, as shown below. Figure 5 The diagram shown is of an ultra-high-definition video broadcasting vehicle. Figure 5 The broadcast van shown is relative to Figure 3, a 4K production system is added for producing 4K production programs. In the 4K switcher, an interface connected with the centralized control system is arranged, and the 4K switcher sends the 4K input signal used by the PGM signal produced by the 4K switcher to the centralized control system. The operations between the 4K switcher and the 8K switcher are independent of each other, and at this time, two modules in the centralized control system control the 4K production system and the 8K production system respectively.

[0100] It should be noted that the resolution of the 8K signal is generally 7680*4320, and the resolution of the 4K signal is generally 3840*2160. That is, generally speaking, the size of each frame of the 8K signal is 4 times that of the 4K signal.

[0101] In the specific implementation, the centralized control system can be provided with a 4K module and an 8K module to control the 4K system and the 8K system respectively.

[0102] In the specific implementation, the first multi-picture monitoring device and the second multi-picture monitoring device can be one monitor. That is, when monitoring, the picture of one monitor is divided into two areas, and the picture of the first multi-picture monitoring device and the picture of the second multi-picture monitoring device are displayed respectively.

[0103] The method provided by the embodiment of the application is a centralized control method of an ultra-high-definition mobile broadcasting vehicle. In the method, the centralized control system finds the identifier of the input device corresponding to the channel number based on the received channel number, and sends a control signal to the multi-picture monitoring device based on the identifier of the input device, so that the identifier of the corresponding input device is displayed on the picture playing the produced program signal in the multi-picture monitoring device. In this way, when video broadcasting is performed, dynamic source name following can be realized, and the cameraman and the director can clearly know which input device is being used, so that the working staff can know the working state of each input device in time.

[0104] Embodiment two

[0105] The embodiment of the application further provides another centralized control method of an ultra-high-definition mobile broadcasting vehicle. The method is applied to a centralized control system. The first switcher and the second switcher can be the same switcher or different switchers. When the video resolutions processed by the two switchers are the same, two videos obtained from the two switchers can be used as backup for each other to prevent interruption of the output video and increase the safety of broadcasting. When the video resolutions processed by the two switchers are different, two original videos with different resolutions and the same content can be generated for multipurpose use. In the embodiment, the first switcher is taken as an 8K switcher, and the second switcher is taken as a 4K switcher, but the application is not limited thereto. As shown in FIG. 6, the method is a centralized control method in a follow-up mode, and specifically includes the following steps. Figure 6 ​

[0106] Step S602, receiving a third channel number sent by the 4K switcher; wherein the third channel number comprises a channel number of an input channel corresponding to a 4K input signal used by the 4K switcher to produce the 4K production program.

[0107] In a specific implementation, the 4K production program is obtained through the following steps 30-32:

[0108] Step 30, for each 8K input device in the plurality of 8K input devices, sending a 4K input signal generated by the current 8K input device to the 4K switcher.

[0109] Step 31, for each 4K input device in the plurality of 4K input devices, sending a 4K input signal generated by the current 4K input device to the 4K switcher.

[0110] Step 32, selecting at least one 4K input signal from the received plurality of 4K input signals to produce a live program by the 4K switcher, to obtain the 4K production program.

[0111] In a specific implementation, the 4K switcher can also send the 4K production program to the second multi-picture monitoring device through the second matrix system. Each 4K input device in the plurality of 4K input devices can also send the 4K input signal generated by the current 4K input device to the second multi-picture monitoring device via the second matrix system, so that the second multi-picture monitoring device displays the 4K input signal output by each 4K input device and the identification of the 4K input device in a small picture.

[0112] Step S604, determining the identification of the selected input device corresponding to the third channel number and the selected monitoring picture in the second multi-picture monitoring device corresponding to the selected input device from the preset relationship data set.

[0113] The relationship data set comprises: a correspondence between the plurality of input devices and the channel numbers of the input channels in the 8K switcher, a correspondence between the plurality of input devices and the channel numbers of the input channels in the 4K switcher, a correspondence between the output channels of the 4K switcher and the channel numbers of the input channels in the 8K switcher, and a correspondence between the plurality of input devices and the monitoring pictures in the second multi-picture monitoring device.

[0114] The input devices include an 8K input device and a 4K input device. In a specific implementation, the relationship data further includes: an identifier of each of the plurality of preset input devices, an identifier of the second switcher output channel, and a correspondence between the output channel of the 4K switcher and a monitoring picture in the second multi-picture monitoring device; and the central control system is further configured to send the identifier of each of the input devices and the identifier of the output channel of the 4K switcher to the second multi-picture monitoring device, so that each monitoring picture in the second multi-picture monitoring device displays the identifier of the played video source.

[0115] In step S606, a second picture control signal is sent to the second multi-picture monitoring device, so that the selected monitoring picture displays the use state of the played video in the selected monitoring picture as use.

[0116] In step S608, a device control signal is sent to the plurality of input devices, so that the selected input device displays the use state of the generated video as use.

[0117] In a specific implementation, part of the input channels of the second switcher (the 4K switcher in this embodiment) correspond to the input channels of the first switcher (the 8K switcher in this embodiment), and the input signals received by the corresponding input channels are the same. The first production program (equivalent to the 8K production program) is obtained by: processing the second production program (equivalent to the 4K production program) to obtain a converted video signal that can be processed by the first switcher; inputting the converted video signal to a linkage channel of the first switcher; and sending an operation instruction to the first switcher according to the third channel number, so that the first switcher performs live production on the received first input signal and / or the converted video signal according to the operation instruction to obtain the first production program; wherein the linkage channel is an input channel of the first switcher.

[0118] In actual application, the second switcher can also be an 8K switcher, and in this case, the second production program is an 8K production program; the first switcher can also be a 4K switcher, and in this case, the first production program is a 4K production program. The processing of the second production program includes up-conversion processing, down-conversion processing, signal format conversion processing, etc., which are not limited here.

[0119] For example, part of the input channels of the 4K switcher correspond to the input channels of the 8K switcher, and the signals received by the corresponding input channels are the same but have different resolutions. The 8K production program is obtained by: performing up-conversion processing on the 4K production program produced by the 4K switcher to obtain an 8K converted signal, inputting the 8K converted signal to a linkage channel of the 8K switcher; and sending an operation instruction to the 8K switcher according to the third channel number, so that the 8K switcher performs live production on the received 8K input signal and / or the 8K converted signal according to the operation instruction to obtain the 8K production program.

[0120] The 8K input signal received by the aforementioned 8K switcher is from multiple preset 8K input devices. The 8K input signal has the same video content as the 4K input signal output by the 8K input device, only the resolution is different.

[0121] The aforementioned step of sending an operation command to the 8K switcher based on the third channel number includes: if the third channel number corresponds to the channel number of the 8K switcher, the operation command is determined to be an instruction to perform on-site production of the 8K input signal input to the input channel of the channel number corresponding to the third channel number in the 8K switcher; if the third channel number includes a channel number other than the channel number corresponding to the 8K switcher, the operation command is determined to be an instruction to perform on-site production of the 8K conversion signal received by the linkage channel. In this method, no director operates the 8K switcher; the 8K switcher follows the operation of the 4K switcher for production.

[0122] In specific implementation, the above relational dataset also includes: the correspondence between the output channels of the 8K switcher and the monitoring screens in the first multi-screen monitoring device; if the third channel number corresponds to the channel number of the 8K switcher, a first screen control signal is sent to the first multi-screen monitoring device so that the usage status of the video played on the selected monitoring screen is displayed as "in use" on the first multi-screen monitoring device.

[0123] To facilitate understanding of the embodiments of the present invention, as follows: Figure 7 The diagram shows a schematic of an ultra-high-definition broadcast vehicle in a servo working mode. Figure 7 The 8K camera is an 8K input device, the 4K camera is a 4K input device, and the camera base station is a base station device. Figure 7 The 8K switcher is equipped with a linkage channel. Each 8K camera outputs 8K and 4K input signals with identical content but different resolutions. The 4K input signal enters the 4K switcher for processing, outputting 4K PGM and 4K PVW signals (wherein, the 4K produced program includes both 4K PGM and 4K PVW signals). The 4K PGM signal is output to the receiver via a second matrix system, and simultaneously up-converted to an 8K converted signal via the up-converter, which is then input to the 8K switcher via the linkage channel. The 8K switcher processes the 8K input signals from the 8K cameras and the 8K converted signals from the 4K switcher based on the operation of the 4K switcher, outputting an 8K PGM signal (equivalent to the aforementioned 8K produced program). This 8K PGM signal is down-converted by a down-converter and then output to the first multi-screen monitoring device for display via the first matrix system. Since the 8K switcher operates in conjunction with the 4K switcher, the centralized control system sends control signals to the multi-screen monitoring device and camera base stations only based on the channel number sent by the 4K switcher.

[0124] It should be noted that in some embodiments, the first switching station and the second switching station described above can also be 4K switching stations, so that the first input device and the second input device can be 4K input devices, and the first production program and the second production program can be 4K production programs, that is, the 8K switching stations in steps S402-S406 can be replaced by 4K switching stations, and the signals related to 8K can be replaced by 4K signals, and the devices related to 8K can be replaced by 4K devices. Similarly, the first switching station and the second switching station described above can also be 8K switching stations, or the first switching station is a 4K switching station and the second switching station is an 8K switching station, etc.

[0125] The super high-definition mobile broadcast vehicle centralized control method displays the names of the video sources on the multi-picture monitoring device, so that the staff in the mobile broadcast vehicle can know the source of the played video, and dynamic source name following is realized. At the same time, the indicator light on the input device prompts the stage staff about the use state of each camera, so that the staff can know the working state of an input device.

[0126] Embodiment three

[0127] The embodiment of the application further provides another super high-definition mobile broadcast vehicle centralized control method, which is applied to a centralized control system. In this embodiment, the first switching station is taken as an 8K switching station, the second switching station is taken as a 4K switching station, and the first input device and the second input device are both taken as 8K input devices, but this is not a limitation. As shown in the figure, the method is a centralized control method in an extended working mode, and specifically includes the following steps: Figure 8

[0128] Step S802 receives a fourth channel number sent by the 8K switching station and a fifth channel number sent by the 4K switching station; wherein the fourth channel number includes the channel number of the input channel corresponding to the signal used by the 8K switching station to produce the 8K production program; and the fifth channel number includes the channel number of the input channel corresponding to the 8K input signal used by the 4K switching station to produce the output video signal.

[0129] In the specific implementation, the output video signal is determined by the following steps 40-42:

[0130] Step 40, in response to a third mode setting operation, set an extended working mode, and bind every 4 processing channels in the 4K switching station as a group of channels for processing and output; wherein the processing channels of the 4K switching station include input channels and output channels.

[0131] Step 41, send the M 8K videos generated by the plurality of second 8K input devices to the 4K switching station in the form of 4M 4K signals through the base station device corresponding to the second 8K input device. ​

[0132] Step 42, each 4K signal in the 4M 4K signals is bound as a group through a multi-processing channel in the 4K switch station, M groups of 4K signals are obtained, a target signal is selected from the M groups of 4K signals for live production, an output video signal is obtained, and the output video signal is sent to an expansion channel of the 8K switch station.

[0133] The above-mentioned 8K production program is determined through steps 50-51 as follows:

[0134] Step 50, for each of the plurality of first 8K input devices, the 8K input signal generated by the current first 8K input device is sent to the 8K switch station through the base station device corresponding to the current first 8K input device, so that the 8K switch station receives a plurality of 8K input signals.

[0135] Step 51, through the 8K switch station, live production is performed on the received plurality of 8K input signals and / or the output video signal received by the expansion channel to obtain an 8K production program; wherein the expansion channel is an input channel of the 8K switch station.

[0136] The above-mentioned first 8K input device and second 8K input device are different 8K input devices. The above-mentioned 8K production program can include PGM signals and PVM signals.

[0137] Step S804, according to the fourth channel sequence number, the fifth channel sequence number and the preset relationship data set, determining the selected input device corresponding to the fourth channel sequence number in the input device, and determining the selected monitoring picture corresponding to the selected input device.

[0138] The above-mentioned input device includes a first input device and a second input device (in this embodiment, the first input device and the second input device are both 8K input devices, in other embodiments, the first input device can also be a 4K input device, and the second input device can also be a 4K input device). The above-mentioned relationship data set includes: a correspondence between each first input device and a channel sequence number of an input channel in the 8K switch station, a correspondence between each second input device and a channel sequence number of an input channel in the second switch station, and a correspondence between an output channel of the 8K switch station and a channel sequence number of an input channel of the 4K switch station, a correspondence between each first input device and a monitoring picture in the multi-picture monitoring device, and a correspondence between the second input device and the monitoring picture in the multi-picture monitoring device.

[0139] Specifically, the above-mentioned step S804 can be implemented through steps 60-62 as follows:

[0140] Step 60, if the fourth channel sequence number does not contain the channel sequence number corresponding to the expansion channel, then from the relationship data set, the first input device corresponding to the fourth channel sequence number is determined as the selected input device.

[0141] Step 61, if the fourth channel sequence number only contains the channel sequence number corresponding to the extended channel, it is determined from the relationship data set that the second input device corresponding to the fifth channel sequence number is the selected input device.

[0142] Step 62, if the fourth channel sequence number contains the channel sequence number corresponding to the extended channel and the channel sequence number other than the channel sequence number corresponding to the extended channel, it is determined from the relationship data set that the first input device corresponding to the fourth channel sequence number and the second input device corresponding to the fifth channel sequence number are selected as the input device.

[0143] In a specific implementation, the relationship data set further includes: the identification of each input device in the plurality of input devices, the identification of the output channel of the 8K switcher, and the correspondence between the output channel of the 8K switcher and the monitoring picture in the multi-picture monitoring device; and the central control system is further configured to send the identification of each input device and the identification of the output channel of the 8K switcher to the multi-picture monitoring device, so that each monitoring picture in the multi-picture monitoring device displays the identification of the played video source.

[0144] Step S806, a picture control signal is sent to the multi-picture monitoring device, so that the selected monitoring picture displays the use state of the played video in the selected monitoring picture as use.

[0145] Step S808, a device control signal is sent to the plurality of input devices, so that the selected input device displays the use state of the generated video as use.

[0146] In order to facilitate the understanding of the embodiments of the present application, as shown in Figure 9 a schematic diagram of an ultra-high-definition mobile broadcasting vehicle in an extended working mode is given, Figure 9The first 8K camera in the first 8K camera group is the first input device, and the second 8K camera is the second input device. In this working mode, the 8K input signals captured by the plurality of first 8K cameras and the plurality of second 8K cameras are sent to the corresponding camera base stations, and the 4K input signals generated by each first 8K camera and each second 8K camera are also sent to the corresponding camera base stations. The camera base stations of the second 8K cameras send the plurality of 8K input signals to the 4K switcher respectively, and the camera base stations of the first 8K cameras send the plurality of 8K input signals to the 8K switcher. Since the 4K switcher can only operate 4K signals, the 8K input signals sent to the 4K switcher are 4 paths of 4K signals that are bound together as a group. Each group of 4 paths of 4K signals is input and output synchronously in the 4K switcher and is produced, that is, the 4K switcher receives the 8K input signals of 4 paths of 4K signals bound together as a group for processing, and outputs the processed 8K video. The processed 8K video is also a group of 4 paths of 4K signals bound together. The processed 8K video is input to the 8K switcher through the expansion channel of the 8K switcher. The 8K switcher receives the 8K input signals sent by the 8K cameras and the 8K video processed by the 4K switcher for processing, and outputs the produced 8K PGM signal and PVW signal. The 8K PGM signal and PVW signal are down-converted into 4K video signals and sent to the first multi-picture monitoring device through the first matrix system.

[0147] For example, the 8K switcher has N input channels, and one of the N input channels is an expansion channel. The 4K switcher has 4M input channels, and the 4M input channels are bound into M groups. The 4K switcher can process M paths of 8K input signals, and the produced 8K video is input to the 8K switcher through the expansion channel. The 8K switcher can also receive N-1 paths of 8K video signals for processing. That is, the production capacity of the 8K video is expanded by binding the 4 paths of channels of the 4K switcher.

[0148] In a specific implementation, the control system can be provided with a 4K module and an 8K module to receive the channel numbers sent by the 4K switcher and the 8K switcher respectively and match them from a preset relationship set. The 4K module and the 8K module cooperate with each other to centrally control the entire mobile broadcast vehicle.

[0149] In this working mode, after the control system receives the channel numbers of the PGM signal and the PVW signal sent by the 4K switcher and the 8K switcher:

[0150] (1) First, it is determined whether the channel number corresponding to the PGM signal (hereinafter referred to as the PGM channel number) in the fourth channel number includes the channel number corresponding to the expansion channel, and whether the channel number corresponding to the PVW signal (hereinafter referred to as the PVW channel number) includes the channel number corresponding to the expansion channel.

[0151] (2) If the PGM channel number does not include the channel number corresponding to the extended channel, the control system only sends control signals to the multi-picture monitoring device and the camera base station based on the first 8K camera (hereinafter referred to as the first PGM camera) corresponding to the received PGM channel number, so that the video played in the monitoring picture of the first PGM camera is displayed as the main output in the multi-picture monitoring device; and the first PGM camera displays the video as the main output.

[0152] (3) If the PVW channel number does not include the channel number corresponding to the extended channel, the control system only sends control signals to the multi-picture monitoring device and the camera base station based on the first 8K camera (hereinafter referred to as the first PVW camera) corresponding to the received PVW channel number, so that the video played in the monitoring picture of the first PVW camera is displayed as the preview cut in the multi-picture monitoring device; and the first PVW camera displays the video as the preview cut.

[0153] (4) If the PGM channel number is only the channel number corresponding to the extended channel, the control system sends control signals to the multi-picture monitoring device and the camera base station through the fifth channel number sent by the 4K switcher, so that the video played in the monitoring picture of the second 8K camera is displayed as the main output; and the second 8K camera displays the video as the main output.

[0154] (5) If the PVW channel number is only the channel number corresponding to the extended channel, the control system sends control signals to the multi-picture monitoring device and the camera base station through the fifth channel number sent by the 4K switcher, so that the video played in the monitoring picture of the second 8K camera is displayed as the preview cut; and the second 8K camera displays the video as the preview cut.

[0155] (6) If the PGM channel number includes the channel number corresponding to the extended channel and other channel numbers, the control system sends control signals to the multi-picture monitoring device and the camera base station through the PGM channel number and the fifth channel number, so that the video played in the monitoring picture of the first PGM camera and the video played in the monitoring picture of the second 8K camera are displayed as the main output; and the first PGM camera and the second 8K camera display the video as the main output.

[0156] (7) If the PVW channel number includes the channel number corresponding to the extension channel and other channel numbers, the centralized control system sends control signals to the multi-picture monitoring device and the camera base station through the PGM channel number and the fifth channel number, so that the video played by the first PVW camera is displayed on the monitoring picture as a pre-cut use, and the video played by the second 8K camera is displayed on the monitoring picture as a pre-cut use; and the first PVW camera and the second 8K camera display the video as a main output.

[0157] For example, the PGM signal sent by the 8K switcher is made of the video sent by the first camera and the video sent by the extension channel; the PVW signal sent by the 8K switcher is made of the video sent by the second camera; the 8K video sent by the 4K switcher to the 8K switcher through the extension channel is made of the video sent by the third camera and the fourth camera. After receiving the above information, the centralized control system sends control signals to the multi-picture monitoring device, so that the red tally light on the monitoring picture playing the video of the first camera, the third camera and the fourth camera flashes, and the red tally light of the first camera, the third camera and the fourth camera flashes; the yellow tally light on the monitoring picture playing the video of the second camera flashes, and the yellow tally light of the second camera flashes.

[0158] It should be noted that in some embodiments, the first switcher and the second switcher can also be 4K switchers, so that the first input device and the second input device can be 4K input devices. Similarly, the first switcher and the second switcher can also be 8K switchers, or the first switcher is a 4K switcher and the second switcher is an 8K switcher, etc., at this time, the resolution of the signals and devices in steps S802-S806 need to be replaced.

[0159] The super high-definition broadcast vehicle centralized control method can make the camera operator and the director clearly understand which input device is being used when video is being broadcast, so that the staff can timely understand the working state of each input device.

[0160] The embodiment of the application also provides another super high-definition broadcast vehicle centralized control method, as shown in Figure 10 The method specifically comprises the following steps:

[0161] Step S902, in response to a mode selection instruction, determining a working mode used for producing a video program; wherein the working mode includes an independent working mode, a follow-up working mode and an extension working mode.

[0162] Step S904, producing a first production program and / or a second production program according to the determined working mode.

[0163] Step S906, the picture control signal is sent to the multi-picture monitoring device through the centralized control system, so that the selected monitoring picture in the multi-picture monitoring device displays the use state of the video played in the selected monitoring picture as use.

[0164] Step S908, the device control signal is sent to the plurality of input devices through the centralized control system, so that the selected input device in the plurality of input devices displays the use state of the generated video as use.

[0165] In a specific implementation, the first switch table is taken as an example of an 8K switch table, the second switch table is taken as an example of a 4K switch table, and the first input device and the second input device are both taken as examples of 8K input devices, but the application is not limited thereto. Among them, some 8K switch tables can be compatible with baseband signals (also known as SDI signals) and IP (Internet Protocol) signals, but some can only process IP signals, so for devices other than 8K switch tables, the video signal of the SDI (Serial Digital Interface) signal needs to be converted to an IP signal through a format converter (abbreviated as IPG) when sent to the 8K switch table, and the IP signal output by the 8K switch table needs to be converted to an SDI signal through a format converter to process and transmit to the next downconverter, matrix system and other devices. In addition, when transmitting IP signals, they are generally transferred through optical switches, that is, the signals input to the 8K switch table are all transmitted through optical switches, and the signals output by the 8K switch table are also all transmitted through optical switches. The 8K switch table includes a control device (hereinafter referred to as LSM), which controls each channel of the 8K switch table to obtain the video sent by the preset input device. In addition, the LSM is also connected with the centralized control system, and the correspondence between the channel number of the 8K switch table and each 8K input device is sent to the centralized control system.

[0166] The 8K switch table and the 4K switch table are connected with the centralized control system through the control server in the switch table, and the control server sends the channel number to the centralized control system. Among them, the control server of the 4K switch table is generally connected with the centralized control system through the I / O interface, and the control server of the 8K switch table is generally connected with the centralized control system through the Ethernet.

[0167] 4K signal is SDI signal, input 8K switcher video signal is all IP format 8K signal, 8K switcher output video signal is also all IP format 8K signal, format converter receives IP format 8K signal and converts it into a group of 4K signal of 4 SDI format, a group of 4 SDI format 4K signal is a 8K video signal. Generally speaking, SDI signal is transmitted through matrix system, IP signal is transmitted through optical switch, matrix system and optical switch are connected with centralized control system to make centralized control system obtain the corresponding relationship of input signal and output signal of matrix system and optical switch.

[0168] Therefore, when 8K switcher can only process IP signal, the structure diagram of the follow-up working mode of the super high-definition mobile broadcast vehicle is as shown in Figure 11 . Figure 11 The matrix 1 and the matrix 2 in the above-mentioned super high-definition mobile broadcast vehicle can be a matrix system. The centralized control system is generally connected with a plurality of camera base stations through GPIO, and the 8K signal input device (which can be an 8K camera) can generally output IP format 8K video signal, SDI format 8K video signal, SDI format 4K video signal and SDI format high definition (HD) video signal, and the camera base station (equivalent to base station device) is used for sending and receiving.

[0169] The above-mentioned super high-definition mobile broadcast vehicle centralized control method can display the name of the video source on the multi-picture monitoring device, so that the staff in the mobile broadcast vehicle can understand the source of the played video, and realize dynamic source name following; the stage staff can also be prompted about the use state of each camera through the indicator light on the signal input device. At the same time, this method also supports centralized control in multiple working modes and supports centralized control in different signal formats.

[0170] In addition, for the above-mentioned centralized control method, the internal connection of the matrix can be controlled by the centralized control system to change the picture arrangement on the multi-picture display device and the video source played by each monitoring picture.

[0171] The above-mentioned embodiments are all exemplified by playing pictures with resolution of 4K on the multi-picture monitoring device, but in fact, according to the use needs, the multi-picture monitoring device not only displays pictures with resolution of 4K, but also displays pictures with high definition or other resolutions. If the monitoring picture of the multi-picture monitoring device is displayed with high definition resolution, the high definition resolution can be directly sent by the input device (such as a camera), or can be obtained by down-conversion through a down-converter.

[0172] Finally, it should be noted that the above-described embodiments are merely specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit the same. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that any person skilled in the art can still modify or easily think of changes to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features, within the technical scope disclosed by the present application.

The output video signal is sent to the extended channel of the first switcher; The first produced program is determined by the following method: for each of the plurality of first input devices, the first input signal generated by the current first input device is sent to the first switcher, so that the first switcher receives multiple first input signals; the first switcher performs on-site production on the received multiple first input signals and / or the output video signal to obtain the first produced program; The extended channel is the input channel of the first switcher.

16. The method according to any one of claims 13-15, characterized in that, In the extended working mode, the step of determining the selected input device corresponding to the fourth channel number based on the fourth channel number, the fifth channel number, and a preset relational dataset includes: If the fourth channel number does not contain a channel number corresponding to the extended channel, then the first input device corresponding to the fourth channel number is determined from the relational dataset as the selected input device. If the fourth channel number only contains the channel number corresponding to the extended channel, then the second input device corresponding to the fifth channel number is determined from the relational dataset as the selected input device; If the fourth channel number includes the channel number corresponding to the extended channel, and channel numbers other than the channel number corresponding to the extended channel, then the first input device corresponding to the fourth channel number and the second input device corresponding to the fifth channel number are determined from the relational dataset as selected input devices.

17. The method according to claim 13, characterized in that, In the extended working mode, the relational dataset also includes: the identifier of each of the multiple input devices, the identifier of the output channel of the first switcher, and the correspondence between the output channel of the first switcher and the monitoring screen in the multi-screen monitoring device; The method further includes: The identifier of each input device and the identifier of the output channel of the first switcher are sent to the multi-screen monitoring device so that each monitoring screen in the multi-screen monitoring device displays the identifier of the source of the video being played.
