Referring to fig. 1-3, the present utility model provides a technical scheme of a 4K external signal processing system:
As shown in figure 1 of the drawings,
A 4K alien signal processing system, comprising:
the multichannel high-definition frame synchronous machine receives input multichannel 4K external signals, and the multichannel signals are not less than 4 paths;
The SDI distributor is used for receiving signals of the multichannel high-definition frame synchronous machine and distributing the signals;
An SDI-IP converter for receiving the signal distributed by the SDI distributor;
and the IP system is used for receiving the signal output by the SDI-IP converter.

The SDI audio de-embedding device is used for performing SDI audio de-embedding after receiving the signals of the progressive interlacing conversion device;
and the baseband system is used for receiving the signal of the SDI audio frequency de-embedding device.
Based on the current 4K signal transmission mode, 4 x 3G SDI is adopted, and the 4 paths of 3G-SDIs adopt a 2SI segmentation mode, so that each path of 3G-SDIs is a complete progressive high definition signal. Therefore, only any 3G-SDI is required to be subjected to progressive interlace conversion, and the down-conversion high-definition SDI signal of the 4K signal can be obtained.
The system designs 4 channels of a multichannel (not less than 4 paths) high-definition frame synchronous machine which is input by 4K 4 x 3G SDI at the same time, and then takes any path to carry out traditional de-embedding and frame synchronization. All input 4-channel signals are output by the multi-channel high-definition frame synchronous machine at the same time, and can still be used as 4K 4 x 3G SDI, and after distribution, the input SDI-IP converter converts the input signals into IP signals and then enters an IP system. And any path of 3G-SDI is simultaneously distributed to the progressive interlacing conversion device on the SDI distributor, and then the video and audio of the path of high-definition signals can be input into the high-definition SDI system as a backup through the SDI audio de-embedding device, so that the system safety is improved.
The system uses simple equipment, utilizes the characteristic of 4K 4 x 3G-SDI 2SI, solves the problem that 4K signals are simultaneously input into an IP system and an SDI system, reduces the transmission link of external signals in the system, simplifies the butt joint work of the external signals, saves the cost and improves the safety of the system.
