Sarnoff® Bitstreams™ Decoder Compliance Tests

Using SRI’s Emmy® award-winning technology, the Sarnoff® Bitstreams™ suite is the de facto standard for systematically and unambiguously testing decoders against industry standards. The Bitstreams visual and automated decoder tests work in a matter of seconds and do not require a reference signal or specialized decoder.

Bitstreams determines the video decoder performance and compliance of virtually any application, from a simulation design to an existing hardware or software product. Integrated circuit designers, major electronics manufacturers, and service providers use these patented visual verification techniques to test their designs and verify their ability to decode complex digital video and HDTV signals.
