The retransmission method for independently manufacturing the double programs can realize independent manufacturing of the 4K video programs and the 8K video programs, namely, a relatively independent 8K retransmission system and a relatively independent 4kK retransmission system can be formed, so that the 8K retransmission system and the 4K retransmission system in the ultra-high definition retransmission vehicle can retransmit two different activities at the same time.

Corresponding to the ultra-high definition rebroadcasting vehicle shown in the above figure 3, the embodiment of the invention also provides a rebroadcasting method for follow-up manufacture, which is a 4K and 8K linkage working mode in the ultra-high definition rebroadcasting vehicle.

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

step S702, in response to the mode setting operation, sets the following switching mode.

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

In a specific implementation, the multipath IP format 8K signal is obtained by one or more of the following modes:

Mode four, a multi-path IP format 8K signal is provided to the switch through a plurality of 8K cameras.

Step S706, the multi-channel SDI format 4K signal is output to the 4K switching station through the matrix switching system, so that the 4K switching station performs on-site production on the multi-channel SDI format 4K signal to obtain the SDI format 4K video program.

Mode six, SDI format 4K signal sent to matrix switching system by 8K caption machine.

Mode seven, a plurality of SDI format 4K signals are transmitted to the matrix switching system by a plurality of 8K cameras.

In specific implementation, a precondition is that the video content received by the channel of the 4K switching station part is the same as the video content received by the channel corresponding to the 8K switching station, and only the resolution is different. Specifically, N IP format 8K signals output by 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 at the same time, the channel order of the SDI format 4K signals of the 8K cameras entering the 4K switching station is consistent with the channel order of the corresponding IP format 8K signals entering the 8K switching station.

Step S708, transmitting 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 up-converts 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 sequence number and the operation content of the SDI format 4K signal adopted by the SDI format 4K video program in the 4K switching station, and sends an operation instruction to the 8K switching station according to the operation channel sequence 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 specific implementation, if the operation channel number corresponds to the channel number of the 8K switching station, an operation instruction for translating the received operation content into an IP format 8K signal input to the channel with the corresponding sequence number of the 8K switching station is obtained; if the operation channel number comprises a number other than the channel number corresponding to the 8K switching station, the operation instruction is determined to output a signal received by the linkage interface, so that the 8K switching station performs field production on the signal received by the linkage interface.

Further, the servo 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, the 8k switching station may have at least 15 signals, 9 signals operating according to the method described above, 1 processing the signals of the 8k slow motion server, 2 processing the signals of the 8k on-line packaging workstation, and 2 processing the signals of the 8k caption machine.

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

And an 8K processing channel behind the slow-motion server channel receives 1-path 8K linkage signals after up-conversion of the 4K video program signals output by the 4K switching station. In addition, 12 4K signals output by 12 4K cameras enter the residual processing channels of the 4K switching station through the matrix switching system. When the 4K switching station operates the processing channels with the same signal source for 8K, the 8K switching station executes the same operation command with the same channel sequence number, namely the follow-up control device controls the 8K switching station to finish the production and output of the corresponding 8K signal. If the current 4K signal operated by the 4K switching station does not have a corresponding 8K signal, for example, when an operation instruction of the switching station relates to M paths of 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 a down-conversion device and then converted into an 8K video program signal (being a 4 paths of synchronous SDI signal) in an SDI format, the 8K signal (IP signal) is converted by a gateway and then sent to a linkage interface of the 8K switching station by a switch, and a follow-up control device controls the 8K switching station to output the 8K signal received by the linkage interface.

In the working mode, the function of the 8K switching table can be synchronously controlled through the 4K switching table, so that the 8K video signal can be output along with the 4K video signal at the same time, an operator is not required to be arranged at the 8K switching table, and the manpower resource is saved.

According to the relay method for the follow-up production, the 8K relay system can follow-up production by following the 4K relay system, and the 8K version and the 4K version of the same video program content are respectively output, so that the reliability of video program playing is improved.

Corresponding to the ultra-high definition rebroadcasting vehicle shown in fig. 4, the embodiment of the invention also provides a rebroadcasting method for expansion production, which is an 8K expansion working mode in the ultra-high definition rebroadcasting vehicle. As shown in fig. 8, the method comprises the following specific steps:

step S802, responding to the binding operation, binding every 4 paths of processing channels in the 4K switching station into a group of channels for processing and outputting; the 4K switching station comprises multiple processing channels.

In step S804, through the second gateway, the received 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 each 4 SDI format 4K signal in the 4M SDI format 4K signals into a group through a multi-channel processing channel, making each group of SDI format 4K signals to obtain a plurality of groups of SDI format 8K video programs, inputting the plurality of groups of SDI format 8K video programs to a third gateway, so that the third gateway converts each group of SDI format 8K video programs into one channel of IP format 8K signal, and sending the converted IP format 8K signals to an 8K switching station through a switch.

Step S808, the 8K switching station is used for carrying out on-site production on the N paths of IP format 8K signals and/or the converted IP format 8K signals, so as to obtain the IP format 8K video program.

The rebroadcasting method for the extension production binds every 4 paths of processing channels of the 4K switching station; further converting 4 paths of SDI output signals of the 4K switching station into 8K signals in a 1 path of IP format through a second gateway, and connecting the 8K signals to one path of processing channel of the 8K switching station; and then after the 4K switching station is used for manufacturing, continuing to manufacture the video program directly sent to the 8K switching station and the video program manufactured by the 4K switching station through the 8K switching station, and finally outputting the 8K video program. This approach can extend the fabrication capability of 8K signals.
