AI Technical Summary
Existing technologies suffer from low data transmission rates and a large number of I/O interfaces in multi-channel PAL video transmission.
The original multi-channel PAL video data is parsed by the interface protocol parsing module, the clock frequency is increased by the cross-clock domain processing module, the video data stream is merged by the multi-channel contention transmission module, and the data parsing and buffering module and the synchronization information reconstruction module are combined to perform data parsing and clock reduction processing, so as to realize high-speed serial transmission between boards of multi-channel PAL video.
It effectively improves the transmission rate between multiple PAL video boards and reduces the number of I/O interfaces.
