Description

technical field

[0001] The invention relates to a multimedia encoding and decoding method, in particular to a real-time multimedia mixed encoding and decoding method for an IP network monitoring system and a video conference system. Background technique

[0002] At present, various network real-time monitoring systems widely used at home and abroad are basically realized by C / C++, and generally use MPEG-4 or H.264 as video encoding, so only image images can be provided. However, a large number of existing video conferencing systems divide the image and audio into two independent signals for encoding and transmission, which takes up a large amount of network bandwidth. Due to the complexity of MPEG-4 and H.264 encoding algorithms, the requirements for hardware performance are very high during encoding and decoding, resulting in the cost of related hardware and software systems being too expensive. It is relatively cost-effective for small and medium-scale production environm...
