Real-time multimedia hybrid encoding and decoding method

Abstract

The invention discloses a real-time multimedia hybrid encoding and decoding method which is applied to an internet protocol (IP) network monitoring system and a video conference system. In the method, real-time multimedia network transmission can be completely realized on the basis of a Java platform, motion joint photographic experts group (MJPEG) video encoding and decoding and Ogg Vorbis audio hybrid compression encoding and decoding; by realizing dynamic hybrid encoding and decoding of video and audio data, the network bandwidth occupancy rate is reduced to the minimum; the method can be applied to various operating system environments, PC terminals and mobile terminals such as mobile phones and the like and seamlessly integrated with various Java-based enterprise-level application systems; and the method has high software and hardware platform general adaptability, high performance and low cost and is easy to deploy.

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...

[0002] At present, various network real-time monitoring systems widely used at home and abroad are basically realized by C / C++, generally using MPEG-4 or H.264 as video encoding, so only image screens 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 environments, public places, and small video conferencing fields. Low

On the other hand, with the rapid development of mobile terminals such as mobile phones, a technical solution with comprehensive functions and easy deployment is required to support real-time network multimedia monitoring and even video conferencing functions on mobile terminals. MPEG-4 and H.264 are too large codes The system and the strict requirements for the operating environment of software and hardware make it impossible for resource-constrained platforms such as mobile phones to meet their requirements.
