The present invention proposes a video encoding and decoding system, method and device with ultra-low end-to-end delay. The system includes a video encoding unit and a video decoding unit. The video encoding unit includes a receiving control module, a video receiving module, and a video downsampling module. , a video encoding module, a first encoding ping buffer module, a first encoding pong buffer module, a second encoding ping buffer module and a second encoding pong buffer module, the receiving control module receives configuration parameters, and ping / pong encoding control signals and configuration parameters Send to the video receiving module, the video down-sampling module and the video encoding module, the video encoding module reads data from the encoding ping / pong cache module and encodes, and sends the encoded video data to the video decoding unit for decoding. The video encoding and decoding system, method and device with ultra-low end-to-end delay implemented in the present invention have the following beneficial effects: the end-to-end delay is relatively small.
Description
technical field [0001] The invention relates to the field of video codec, in particular to a video codec system, method and device with ultra-low end-to-end delay. Background technique [0002] At this stage, video encoding and decoding equipment is widely used in all aspects of social life. Ordinary applications include video conferencing, traffic monitoring, etc.; special applications include military reconnaissance, unmanned aerial vehicles, remote control, missile guidance and control, and machine vision. For the above-mentioned special applications, video images need to be used for real-time control, so there are strict requirements on the end-to-end delay when the video is transmitted from the encoding device to the decoding device. The end-to-end delay of ordinary security monitoring video codec equipment is generally 300-500ms, and the end-to-end delay of some audio and video codec equipment optimized for low-latency is 120-180ms. For special applications such as m...
