AVS2

AVS2 (Advanced Video System 2) is a video coding standard developed by the AVS2 Working Group, a collaboration of experts from China, Hong Kong, and Macau. It was finalized in 2017 and is designed to provide high compression efficiency and good video quality, making it suitable for various applications such as video streaming, broadcasting, and storage.

The standard is based on the AVS1 (Advanced Video System 1) standard, which was developed in 2003. AVS2 builds upon AVS1 by introducing several new features and improvements. These include advanced intra prediction, enhanced inter prediction, and more flexible partitioning structures. The standard also supports higher resolutions, including 4K and 8K video, and provides better error resilience and scalability.

AVS2 uses a block-based hybrid video coding framework, similar to other standards like H.264/AVC and HEVC/H.265. It employs motion compensation, transform coding, and entropy coding to achieve efficient compression. The standard supports various profiles and levels to accommodate different application requirements, such as real-time communication, media storage, and broadcasting.

One of the key advantages of AVS2 is its high compression efficiency. It can achieve similar or better video quality compared to H.264/AVC and HEVC/H.265 at lower bitrates. This makes AVS2 an attractive option for service providers looking to reduce bandwidth costs and improve user experience.

AVS2 has gained recognition and support in the Asia-Pacific region, where it is used in various applications, including digital television, video on demand, and mobile video. The standard has also been adopted by some international organizations and is being considered for use in other regions.

The AVS2 Working Group continues to develop and maintain the standard, addressing any issues or feedback from users and making necessary updates to ensure its relevance and effectiveness. The standard is open and royalty-free, allowing for widespread adoption and implementation.
