In April 2011, Tensilica announced that it was the first audio IP core supplier to be awarded DTS Broadcast and DTS DMP (Digital Media Player) certification. The certification, achieved using fully optimized software implementation on Tensilica's  HiFi 2 and HiFi EP Audio DSP IP cores, provides developers of SOCs with a proven solution that reduces the time to market for new, fully compliant designs.

"Tensilica's highly efficient HiFi Audio DSP combined with DTS Broadcast and DMP products will quickly enable development of next generation digital televisions, STBs and digital media players," stated Brian Towne, executive vice president and chief operating officer at DTS. "Furthermore, consumers buying these devices will benefit from superior quality audio, providing a richer, more meaningful entertainment experience."

The DMP package allows decoding of popular DTS content by creating a stereo mix-down and provides a DTS 5.1 digital bit-stream to external home theater systems.  The DTS broadcast package incorporates all the functionality of the DMP package and extends this to target DTS 5.1 core content delivered over traditional cable, satellite, terrestrial and IP networks. It also supports infrastructures such as Video-on-Demand, IPTV and managed networks.  The certified packages, when implemented in a product, ensure consumers have access to the highest quality audio experience that only DTS can deliver.
