Digital audio solution
has room for improvement

A new DTS 96/24 solution combines a certified decoder with a complete software system - including auto-detection, I/O and stream management - while only using 30-40% of the Aureus DSP

A new DTS 96/24 solution from Texas Instruments combines a certified decoder with a complete software system - including auto-detection, I/O and stream management - while only using 30-40% of the Aureus DSP. This allows manufacturers to use the additional performance to differentiate their products by adding post-processing features, such as dual digital zones, speaker virtualisation and automatic room correction.

'DTS 96/24 enables the ultimate in entertainment for consumers and opens up a number of new options for DVD-based high resolution audio', said Kazuyuki Neida, Director, AV and IC Licensing at DTS.

'We are very excited about such an efficient implementation of the DTS 96/24 standard.

We believe the extra performance that TI's optimised solution offers will enable OEMs to deliver this technology across a variety of next-generation products'.

DTS 96/24 is the only system that: provides 5.1 channels of 96/24 along with full-motion video on DVD-video and DVD-audio (video zone); is compatible with all DVD-video players; and is accessible through the digital output.

'When you deliver a complete DTS 96/24 system solution with 60-70% of the performance still available for customer differentiation, cool things are going to happen', said Curt Moore, WW Business Manager of TI's Performance Audio Group.

'OEMs can not only offer additional differentiated features on their high end systems, but they can also start migrating these features to the low cost, high volume market segments'.

TI's TMS320DA610 is a 32/64bit floating point DSP optimised for home audio receivers.

Using the DA610 DSP's audio software framework, customers can quickly differentiate their product through the use of eXpressDSP software and development tools, which includes the easy-to-use Code Composer Studio integrated development environment.

At 225MHz, the DA610 offers the highest performance available in the audio industry with 1800MIPS or 1200MFLOPS.

With it, manufacturers will be able to provide consumers with a full suite of high-quality surround sound content and still have headroom to add additional effects processing and other enhancements.

Until now, these enhancements have only been available on high-end audio receivers.

They can include: dual digital zone, which allows users to play a DVD in one room and another audio source in a different room through the same receiver; virtualisation, which lets users position speakers anywhere in a room while still achieving true surround sound; automatic room correction, which automatically adjusts speakers to maximise the audio presentation despite the limitations due to room size or speaker placement; access to additional formats, which gives manufacturers unlimited opportunity to differentiate their products; and more channels for higher sampling frequencies for a more life-like listening experience.

The Aureus platform is based on the proven silicon and tools of the code-compatible TMS320C6000T DSP platform, the world's highest performing DSP.

The DA610 DSP's audio software framework is accessible through TI's easy-to-use Code Composer Studio development tools.
