In the rebroadcasting method, the content of the 8K online packaging signal is the same as that of the 4K online packaging signal, and the 8K online packaging signal and the 4K online packaging signal are generally from an 8K online packaging workstation or a 4K online packaging workstation, namely the 8K online packaging workstation generates the 8K online packaging signal and then down-converts the 8K online packaging signal into the 4K online packaging signal to obtain the 8K online packaging signal and the 4K online packaging signal with the same content; or the 4K online packaging workstation generates a 4K online packaging signal and then performs up-conversion on the 4K online packaging signal to obtain an 8K online packaging signal and a 4K online packaging signal with the same content, and the 8K online packaging workstation with partial models can output a native 4K online packaging signal without down-conversion processing.

In the rebroadcasting method, the 8K caption generator signal and the 4K caption generator signal have the same content and generally originate from an 8K caption generator or a 4K caption generator, that is, the 8K caption generator generates the 8K caption generator signal and then down-converts the 8K caption generator signal into the 4K caption generator signal to obtain the 8K caption generator signal and the 4K caption generator signal with the same content; or 4K caption generator signals are generated by the 4K slow motion server and then are up-converted into 8K caption generator signals, so that 8K caption generator signals and 4K caption generator signals with the same content are obtained, and native 4K caption generator signals can be output by 8K caption generators with partial models, and at the moment, down-conversion processing is not needed.

Step S606, sending a plurality of SDI format 4K signals to a down-conversion device through a matrix exchange system, so that the down-conversion device performs down-conversion processing on the received plurality of SDI format 4K signals to obtain high-definition signals, and sending the high-definition signals to a first video distribution amplifier; the first video distribution amplifier sends the high-definition signal to a tail board or a camera for returning.

The above-mentioned relaying method of the independent making of double-program can realize the independent making of 4K video program and 8K video program, namely can form relatively independent 8K relaying system and 4kK relaying system, so that 8K relaying system and 4K relaying system in the ultra high definition relaying car can relay two different activities at the same time.

Corresponding to the ultra high definition relay truck shown in fig. 3, an embodiment of the present invention further provides a relay method for follow-up production, where the method is a 4K and 8K linkage work mode in the ultra high definition relay truck.

As shown in fig. 7, the method includes the following specific steps:

in step S702, a follow switching mode is set in response to a mode setting operation.

Step S704, the switch outputs the multi-channel IP format 8K signal to the 8K switching station.

In a specific implementation, the multi-path IP format 8K signal is obtained by one or more of the following ways:

And in the fourth mode, a plurality of 8K cameras are used for providing the multi-path IP format 8K signals to the switch.

Step S706, outputting the multiple SDI format 4K signals to the 4K switching station through the matrix switching system, so that the 4K switching station performs field production on the multiple SDI format 4K signals to obtain the SDI format 4K video program.

The multi-path SDI format 4K signal is obtained through one or more of the following modes:

And the mode IV is that SDI format 4K signals are sent to the matrix switching system through the 8K slow motion server.

And fifthly, transmitting SDI format 4K signals to the matrix switching system through the 8K online packaging workstation.

And the mode VI is that SDI format 4K signals are sent to the matrix switching system through an 8K caption machine.

And the seventh mode is that the multiple SDI format 4K signals are sent to the matrix switching system through the multiple 8K cameras.

In a specific implementation, a precondition is that the video content received by a partial channel of the 4K switching station is the same as the video content received by a corresponding channel of the 8K switching station, and only the resolution is different. Specifically, N IP format 8K signals output by the N8K cameras may enter the first N processing channels of the 8K switching station through the switch, N native SDI format 4K signals output by the N8K cameras enter the first N processing channels of the 4K switching station through the matrix switching system, and meanwhile, the order of the channels of the SDI format 4K signals of the 8K cameras entering the 4K switching station is consistent with the order of the channels of the IP format 8K signals corresponding thereto entering the 8K switching station.

Step S708, sending the SDI format 4K video program to an up-conversion device through a matrix switching system by a switching station, so that the up-conversion device performs up-conversion on the SDI format 4K video program to obtain a converted SDI format 8K signal; and carrying out format conversion on the converted SDI format 8K signal through a seventh gateway to obtain an IP format 8K signal, and inputting the obtained IP format 8K signal to a linkage interface of the 8K switching station through a switch.

Step S710, the following control device monitors the operation channel serial number and the operation content of the SDI format 4K signal adopted by the SDI format 4K video program obtained from the 4K switching station, and sends an operation instruction to the 8K switching station according to the operation channel serial number and the operation content, so that the 8K switching station performs on-site production on the received 8K signal according to the operation instruction, and outputs the IP format 8K video program.

In the concrete implementation, if the operating channel serial number corresponds to the channel serial number of the 8K switching station, an operating instruction for translating the received operating content into an IP format 8K signal input to the channel with the serial number corresponding to the 8K switching station is obtained; and if the operating channel serial number contains serial numbers except the channel serial number corresponding to the 8K switching station, determining the operating instruction as a signal received by the output linkage interface so that the 8K switching station carries out field production on the signal received by the linkage interface.

Furthermore, the follow-up control device can translate the actions of the 4k slow motion server, the 4k online packaging workstation and the 4k caption machine into the actions of the 8k slow motion server, the 8k online packaging workstation and the 8k caption machine. For example, an 8k switching station may have at least 15 signals, 9 signals operating according to the method described above, 1 processing 8k slow motion server signals, 2 processing 8k on-line packing workstation signals, and 2 processing 8k subtitling machine signals.

For the convenience of understanding the working mode, it is assumed that the 8K switching station can process 20 channels of 8K signals, wherein the first 8 channels receive video signals of 8K cameras, and the processing channels after the 8 th channel receive 8K caption signals and 8K key signals of a caption machine, 8K on-line packing signals, and 8K slow motion signals, respectively. Meanwhile, the 8K cameras output 8 paths of 4K signals (SDI signals) which are sequentially accessed to the front 8 paths of processing channels of the 4K switching station according to the channel access sequence of the 8K switching station; meanwhile, the processing channels after the 8 th channel respectively receive 4K caption signals and 4K key signals of the caption machine, 4K on-line packaging signals and 4K slow motion signals, and all the signals are accessed into the corresponding channels of the 4K switching station strictly according to the channel serial number accessed into the 8K switching station.

And receiving the 1 path of 8K linkage signals after the up-conversion of the 4K video program signals output by the 4K switching station in an 8K processing channel behind the slow motion server channel. In addition, 12 paths of 4K signals output by 12 4K cameras respectively enter the rest processing channels of the 4K switching station through a matrix switching system. When the 4K switching station operates the 8K processing channels with the same signal source, the 8K switching station will execute the same operation command with the same channel number, that is, the follow-up control device controls the 8K switching station to complete the production and output of the corresponding 8K signal. If the 4K signal of the current 4K switching station operation does not have a corresponding 8K signal, for example, when the operation command of the switching station relates to M-channel 4K camera signals, the output 4K signal does not correspond to the 8K signal, at this time, the 4K video program signal output by the 4K switching station is up-converted by the down-conversion device and then converted into an SDI format 8K video program signal (which is a 4-channel synchronous SDI signal), and after the SDI signal is converted into an 8K signal (IP signal) by the gateway, the switch sends the 8K video program signal to the linkage interface of the 8K switching station, and the follower control device controls the 8K switching station to output the 8K signal received by the linkage interface.

In this mode, can switch the function that platform synchro control 8K switched over the platform through 4K for 8K video signal can follow 4K video signal and export simultaneously, and do not need 8K to switch platform department to have the operating personnel, has saved manpower resources.

According to the follow-up production rebroadcasting method, the 8K rebroadcasting system can follow the 4K rebroadcasting system to carry out follow-up production, and respectively output the 8K version and the 4K version of the same video program content, so that the reliability of video program playing is improved.

As shown in fig. 8, the method includes the following specific steps:

Step S804, format conversion is performed on the received M-channel IP format 8K signal through the second gateway, the M-channel IP format 8K signal is converted into a 4M-channel SDI format 4K signal, and the converted 4M-channel SDI format 4K signal is input to the 4K switching station.

Step S806, binding every 4M SDI format 4K signals in the 4M SDI format 4K signals into one group through the multi-channel processing channel, making each group of SDI format 4K signals to obtain multiple groups of SDI format 8K video programs, inputting the multiple groups of SDI format 8K video programs into a third gateway, enabling the third gateway to convert each group of SDI format 8K video programs into one path of IP format 8K signals, and sending the converted IP format 8K signals to an 8K switching station through a switch.

And step S808, carrying out field production on the N paths of IP format 8K signals and/or the converted IP format 8K signals through the 8K switching station to obtain an IP format 8K video program.
