AVS3 Elementary Streams

Test AVS3 video decoders compliance

AVS3 Elementary Streams

Allegro DVT compliance bitstreams are designed for intensive testing of AVS3 decoder implementations.

AVS3, China’s latest video coding standard, is being developed by the AVS working group with a target to provide the most competitive low royalty codec standard, achieve higher compression efficiency and provide suitable video coding technology for 8K ultra-high definition media and emerging 5G applications such as virtual reality media, smart security and video streaming. Allegro DVT is an active member of the AVS working group and is closely involved in the development of the AVS3 coding standard.

Unique Selling Points

  • Avoids expensive re-design phases and shortens development cycles. Due to their high complexity, video decoders need to be extensively validated ahead of production.
  • Strengthens the decoder against all encodings, existing or to come, to extend final products’ life.


  • IP and IC vendors, system vendors (set-top boxes, digital TVs, smartphones, tablets, etc.).


  • Elementary streams suite, each stream focusing on a specific video feature to allow fast and simple analysis of potential issues.
  • Complete reference documentation.

Technical Features

Syntax streams ensure that decoders abide by all features of AVS3 compression standard, including corner cases.
