Secretary general Huang Tiejun of the Audio Video Coding Standard Workgroup of China (AVS Workgroup) revealed recently that the nationally approved standard for audiovisual encoding and decoding would officially take effect from November 1. During the one-year implementation period, digital televisions may support MPEG-2 or other audiovisual standards, but AVS codec support will be mandatory in all digital TVs sold in China from November 1, 2012 onwards. The standard is derived from the contents of the General Specifications for Terrestrial DTV Devices and General Specifications for Terrestrial DTV Receivers, both issued this June.
AVS also announced the launch of its open-source site (opensource.avs.org.cn), featuring open-source AVS encoding, real-time transcoding, and decoding code that terminal makers and individual users will be able to use to develop their own products and services incorporating the AVS standard.
Huang said that manufacturers would be required to pay RMB 1 per DTV terminal toward the AVS patent pool starting from November 1, 2012. An estimated 50 mln TV sets are sold in China every year.
