DSPs provide high-quality audio

DA7xx DSPs are the first audio processors approved for both DTS-HD and Dolby TrueHD and can support all audio formats present on next-generation HD DVD and Blu-Ray discs.

Texas Instruments' audio digital signal processors (DSPs) are the first embedded implementation approved with DTS-HD master audio at 192kHz for unparalleled audio quality in home theatre systems.

Audio/video receivers (AVRs) based on TI's DA7xx generation of DSPs have the power to fully support eight channels of 192kHz lossless audio, immersing consumers in the theatre experience.

An acoustic performance that is bit-for-bit identical to the original audio source allows home systems to sound exactly as the filmmaker intended.

With the full certification of DTS-HD Master audio and DTS-LBR (Low Bit Rate), DA7xx DSPs are the first audio processors approved for both DTS-HD and Dolby TrueHD and can support all audio formats present on next-generation HD DVD and Blu-Ray discs.

"The consumer electronics industry continues to demand the highest quality surround sound in home theatre systems", said Brian Towne, Senior Vice President and General Manager, DTS.

"With TI's DSP-based A/V receivers that are DTS-HD certified, consumers will now have unprecedented audio that matches high-definition video images for a truly all-encompassing HD home theatre experience".

Decoding the highest quality DTS-HD master audio streams, eight-channel/192kHz lossless audio and all essential post-processing can be handled on a single DA7xx DSP.

By supporting DTS-HD master audio in a cost-effective, single-chip solution, manufacturers can incorporate crisper, fuller and more dynamic audio quality into lower-priced home theater systems.

TI integrated the new DTS-HD audio decoders into the existing DA7xx software solution and system framework, allowing manufacturers to get DTS-HD products to market quickly without any compatibility problems.

TI's audio framework enables original equipment manufacturers (OEMs) to easily plug in differentiating post-processing modules from TI or TI third parties, including Audyssey MultEQ XT, Neural-THX Surround, SRS Circle Surround II and THX Ultra 2.

The Aureus Engine, TI's DA7xx DSPs or Aureus processors target a wide range of home theatre and automotive products requiring multi-channel decoding and high-speed encoding.

TI's Aureus product line consists of a 32/64bit floating-point programmable DSP and a comprehensive software solution, enabling multi-channel decoding applications.

TI offers a wide range of complementary high-performance analogue and DSP products for home entertainment audio, including audio data convertors, Class-D and PurePath Digital audio amplifiers and audio clocks.
