Independent Certification of MPEG Interoperability
The market for MPEG-based products and services is here and is expanding rapidly. Timely product introduction, compliance with standards and interoperability provide a competitive advantage in today's marketplace. Sarnoff's compliance bitstreams are the key to reducing your time to market and establishing your product. They provide a rapid, independent certification of MPEG video decoders and are thorough and easy to use.
Sarnoff's Video Compliance Bitstreams are used to certify DSS satellite receivers, the fastest selling consumer electronics product of all time.
Example showing visual confirmation of pass/fail for Quant Matrix test:

Title Screen indicates test being performed.

VERIFY screen shows successful completion of exhaustive test.

Corrupted VERIFY screen clearly shows failure of decoder under test.
