standards are ubiquitous, affecting the lives and business of citizens, companies and governments in a multitude of ways. As governments around the world realised the economic consequences stemming from standardisation, newcomers to the international standardisation arena have found themselves at a disadvantage owing to a lack of expertise and skills to contribute to the process, and the 'barring' strategies practiced by the keepers of the system in part as a result of the Intellectual Property Rights (IPR) royalties they collect from globally imposed standards. In this paper, we use the case of China's audio video coding standard (AVS) to examine government positions and possible strategies for standard market competition in the presence of a dominant international standard. In our analysis, we adopt a system perspective on the Chinese government's market intervention policy.

To achieve copyright protection by noticing the serious problem of copyright piracy,a novel watermarking algorithm based on motion vector of AVS (audio video coding standard) was *** the inter prediction step of AVS video compression standard,watermark embedding is implemented by modifying the resolution of the motion vectors of partition blocks in different macroblock *** modulation is based on the mapping rules between the motion vector resolution and the watermark *** last,the prediction modes of current macroblock is determined using standard AVS coding algorithm which will ensures that the best prediction mode is selected for current watermarked *** experimental results show that the presented watermarking method achieves comparatively high embedding rate without complicated computation,and has almost no impact on video bitrate and video quality subjectively as well as objectively.
