產品概述 The AVS standard is the series of 'information technology advanced Audio and Video Coding' standard abbreviation. The AVS standard includes four main technical standards: system, video, audio and digital copyright management.
The fully Intellectual Property of second generation Source Coding-Decoding Standard – AVS is owned by China.
The AVS source coding technology mainly focuses on mass video and audio (original data and sources) compression technology, also known as Digital Video and audio coding technology. Obviously, as the premise of digital information transmission, storage and broadcast it is also the general foundation character standard of the digital video& audio industry.
On 30th April, 2005, AVS standard video part officially passed the public show and became the national standard.
