Committed to innovations that provide the highest performance audio quality, Texas Instruments Incorporated (TI) has 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 TI’s award-winning DA7xx generation of DSPs have the power to fully support eight channels of 192 kHz lossless audio, immersing consumers in the ideal theater 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 theater 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 theater experience.”
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.
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 theater and automotive products requiring multi-channel decoding and high-speed encoding. TI’s Aureus product line consists of a 32/64-bit floating-point programmable DSP and a comprehensive software solution, enabling multi-channel decoding applications.
