VP9 Elementary Streams

Test VP9 video decoders compliance

VP9 Elementary Streams

Allegro DVT compliance bitstreams are designed for intensive testing of VP9 decoder implementations.

VP9 codec is a royalty-free, high-efficient video compression technology developed by the Google-sponsored WebM Project. It offers increased compression efficiency that enables next generation online streaming services with resolutions up to 4K (e.g. YouTube) and WebRTC-based video conferencing applications.

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.

Customers

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

Deliverables

  • 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 VP9 compression standard, including corner cases.
