Cambridge firm has IP to test Google VP9 codec standard

Argon Design, a Cambridge-based developer of video compression chip test technology, has signed a licensing agreement with Renesas Electronics. It involves IP for compliance testing to Google’s VP9 codec standard.

Sample video frame from an Argon Streams VP9 bit-stream, shows the directed random number based approach.

Argon Streams VP9 is a set of conformance test bit-streams providing full coverage and verification of VP9 video decoders.

The bit-streams are derived directly from Google’s VP9 Reference Code using the same compiler technology that was developed for Argon’s highly successful HEVC bit-streams.

The process uses directed random numbers to ensure that the bit-streams provide comprehensive coverage testing of all functions, value ranges and cross coverage combinations in the particular specification. Argon Streams VP9 includes full support for VP9 profiles 0, 1, 2 and 3.

Hirotaka Hara, senior chief professional at Renesas Electronics said:

“As a leading semiconductor vendor, it is critical that our designs fully conform with emerging video codec standards such as VP9. While searching for a conformance test solution, we recognised that Argon Streams was the only solution to guarantee full coverage testing of our video decoders.”
