TI Announces Industryís First Approved DTS-HD Master Audio DSP Implementation for Audio/Video Receivers


TIís DA7xx Audio DSPs Enrich Audio Quality for Consumers Watching HD DVDs and Blu-ray Discs

HOUSTON. - Committed to innovations that provide the highest performance audio quality, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced that its audio digital signal processors (DSPs) are the first embedded implementation approved with DTS-HD master audio at 192 kHz for unparalleled audio quality in home theater systems. Audio/video receivers (AVRs) based on TIís award-winning DA7xx generation of DSPs have the power to fully support eight channels of 192 kHz lossless audio that is bit-for-bit identical to the original audio source, which allows home theater 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.

ďThe consumer electronics industry continues to demand the highest quality surround sound in home theater systems,Ē said Brian Towne, senior vice president and general manager, DTS. ďWith TIís 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 theater experience.Ē

Cost-Effective Performance

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.

TIís 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

TIís DA7xx DSPs or Aureus processors target a wide range of home theater and automotive products requiring multi-channel decoding and high-speed encoding. TIís Aureus product line consists of a 32/64-bit floating-point programmable DSP and a comprehensive software solution, enabling multi-channel decoding applications.

TI offers a wide range of complementary high-performance analog and DSP products for home entertainment audio, including audio data converters, Class-D and PurePath DigitalTM audio amplifiers and audio clocks. TI provides the silicon, software, systems expertise and support for the entire audio signal chain, enabling customers to get to market quickly. For more information see the Audio Solutions Guide at
