Distributed Screen Recording and Transmitting System Based on HiSilicon Video SoC

In this paper, a distributed screen recording and transmission system based on HiSilicon video SOC is implemented. The system is based on embedded hardware architecture, which can realize the acquisition, compression, storage and transmission of VGA/DVI and other screen video data. Based on the advanced H.265 video compression algorithm, the system can continuously record the screen data for more than 260 hours at 8Mbps bit rate, and the recorded data can be played back through DVI interface. At the same time, the system can realize real-time transmission and centralized monitoring of multi-channel video data. Experiments show that when the video input format is 1920* 1080@60Hz, the end-to-end delay is less than 70ms.
