Because cable television networks have not yet undergone large-scale upgrades, they lack the capability to transmit 8K ultra-high-definition video programs. However, 8K TVs are already in mass production, and outdoor large-screen display devices capable of playing 8K ultra-high-definition video are appearing in large numbers. High-performance 5G mobile phones also support receiving and playing 8K ultra-high-definition video. All of this urgently requires solutions that can more easily transmit 8K / 4K ultra-high-definition video to terminal playback devices such as 8K / 4K TVs, 8K / 4K set-top boxes, outdoor large-screen display devices, and 5G mobile phones.

[0003] Meanwhile, most of the television broadcasting vans currently in use lack satellite broadcasting capabilities. When these vans are conducting live / rebroadcast operations in outdoor locations such as stadiums, large-scale performance venues, or large conference venues, they often need to be accompanied by a dedicated satellite communication van or satellite broadcasting van to relay the program signals output by the van to satellite receiving equipment in various locations via television broadcasting satellites.

[0063] The aforementioned 4K switcher 21 performs on-site production of the 4K video signal from the target channel among the received multiple 4K video signals to obtain a 4K video program signal, which is then sent to the second embedding module 32. The audio production system 30 receives audio signals corresponding to the multiple 4K video signals received by the 4K switcher, as well as other audio signals from other channels. It switches, synthesizes, and performs on-site production of the audio signals to obtain a second audio signal, which is then sent to the second embedding module 32. The second embedding module 32 embeds the second audio signal into the 4K video program signal and outputs the embedded 4K signal.

[0064] In a specific implementation, the aforementioned broadcast vehicle also includes an 8K video distribution amplifier 33 connected to the first embedding module 31, and a 4K video distribution amplifier 34 connected to the second embedding module 32. The first embedding module 31 uses the 8K video distribution amplifier 33 to copy the embedded 8K signal into multiple channels, which are then sent to the 8K monitoring system 11, the 5G communication equipment 12, the satellite broadcasting equipment 13, and the rear panel of the vehicle.

[0065] The aforementioned second embedding module 32 uses a 4K video distribution amplifier 34 to copy the embedded 4K signal into multiple channels, which are then sent to the 4K monitoring system 22, the 5G communication equipment 12, the satellite broadcasting equipment 13, and the vehicle tailgate, respectively.

[0066] Figure 3 In the broadcast van shown, an 8K signal source can provide 8K video signals in SDI format and send these signals to a 5G backpack. The 8K encoder in the 5G backpack then encodes the SDI 8K video signal and outputs the encoded signal to a 5G transmission device within the backpack. The 5G transmission device then transmits the encoded signal via a 5G mobile communication network to a 5G terminal (equivalent to...). Figure 3 In the 5G CPE (5G terminal), the 5G terminal sends the encoded signal to the decoding server, which decodes the encoded signal and transmits it as an SDI signal to the ultra-high-definition IP-SDI converter 2 (equivalent to...). Figure 3 The IPG2 in the middle converts the received video signal into an 8K video signal in IP format and then transmits it to the 8K switcher 10. The 8K switcher can process the received 8K video signal and send the processed 8K video program signal to the ultra-high-definition IP-SDI converter 1 (equivalent to...). Figure 3 The IP format 8K video program signal is converted into an SDI format 8K video program signal and then transmitted to the first embedding module 31.

[0067] The 8K signal source can also directly send IP-formatted 8K video signals to the 8K switcher, enabling the 8K switcher to perform on-site production of the received 8K video signals, obtaining 8K video program signals, which are then converted into SDI-formatted 8K video program signals and sent to the first embedding module 31. The 8K signal source can also send IP-formatted 8K video signals to the IPG1, which simultaneously contains audio signals. The IPG1 can convert the IP-formatted video signals into SDI-formatted 8K video signals. After de-embedding, the SDI-formatted 8K video signals yield audio signals extracted from the 8K video signals, which are then sent to the audio production system 30.

[0068] Similarly, the 4K signal source can provide 4K video signals in SDI format and send them to the 5G backpack. The 4K encoder in the 5G backpack encodes the SDI 4K video signal and outputs the encoded signal to the 5G transmission equipment in the backpack. The 5G transmission equipment then outputs the encoded signal (in SDI format) to the matrix module 20. The 4K signal source can also directly send SDI 4K video signals to the 4K switcher. These 4K video signals contain both video and audio signals. After de-embedding, the audio signal extracted from the 4K video signal is obtained and sent to the audio production system 30.

[0069] In its specific implementation, the aforementioned satellite relay equipment includes an 8K encoding device, a 4K encoding device, a signal frequency conversion and modulation device, a signal power amplification device, and a waveguide device. The 8K encoding device encodes the received 8K video program signal to obtain an 8K ultra-high-definition video TS stream signal, and sends the 8K ultra-high-definition video TS stream signal to the signal frequency conversion and modulation device. The 4K encoding device encodes the received 4K video program signal to obtain a 4K ultra-high-definition video TS stream signal, and sends the 4K ultra-high-definition video TS stream signal to the signal frequency conversion and modulation device. The signal frequency conversion and modulation device modulates and frequency-converts the received 8K ultra-high-definition video TS stream signal or the 4K ultra-high-definition video TS stream signal to obtain a processed TS stream signal, and sends the processed TS stream signal to the signal power amplification device. The signal power amplification device amplifies the processed TS stream signal to obtain a power amplified signal, and sends the power amplified signal to the waveguide device. The waveguide device transmits the power amplified signal to the satellite transmitting antenna, so that the satellite transmitting antenna transmits the power amplified signal to the satellite for relay by the transponder on the satellite.

[0070] Specifically, the aforementioned 5G communication equipment 12 also includes an 8K encoding device, a 4K encoding device, and a 5G terminal (equivalent to...). Figure 3The 8K encoding device is used to encode the received 8K video program signal and send the encoded signal to the 5G terminal for output; the 4K encoding device is used to encode the received 4K video program signal and send the encoded signal to the 5G terminal.

[0071] The aforementioned 8K ultra-high-definition video OB van, supporting 5G live streaming, can perform on-site program production and forwarding via wireless communication networks and satellite transmission links. The OB van includes an 8K switcher based on the VoIP protocol and a multi-channel 4K switcher based on SDI signal links, capable of simultaneously producing two different 8K and 4K programs. The 4K switcher can also be used as a backup for the 8K switcher. The ultra-high-definition OB van can receive video signals captured by cameras via wireless communication networks, supporting the encoding of programs into video streams of different resolutions such as 8K ultra-high-definition, 4K ultra-high-definition, and high-definition. These streams are then transmitted to playback terminals via wireless communication networks and content delivery networks, or via satellite transmission links. Live ultra-high-definition video streaming via wireless communication networks significantly reduces the number of connecting cables, and transmitting produced programs via wireless communication networks and satellite transmission links makes it much easier to deliver programs to playback terminals.

[0072] Currently, due to the large data volume of 8K / 4K ultra-high-definition video signals, many applications use the IP protocol for transmission. When some devices do not support IP-formatted 8K / 4K ultra-high-definition video signals, an ultra-high-definition IP-SDI converter can be used to convert the IP-formatted video signal to the SDI-formatted video signal. Simultaneously, an ultra-high-definition IP-SDI converter can also convert SDI-formatted video signals to IP-formatted video signals.
