JVC Chooses 32/64bit Audio DSP from Texas Instruments for its New RX-DP20VBK A/V Receiver

10/1/2002 - JVC has selected a 32/64bit floating-point audio digital signal processor (DSP) from Texas Instruments Incorporated (TI) for its latest Audio/Video (A/V) receiver, the RX-DP20VBK. Optimized for digital audio applications, the TI device enables JVC to quickly and easily deliver a compelling, realistic listening experience and create a feature-rich, cost-effective system.

Scheduled to be available in January of 2003, the JVC RX-DP20VBK audio/video control receiver will offer one of the most complete home theater experiences available. With 7.1 multi-channel high-resolution audio capabilities, the receiver is fully compatible with all audio formats including DVD-Audio systems, Dolby Digital 5.1, Home THX and THX Ultra 2 Certified Surround EX. TI's solution also brings sophisticated dual-zone capabilities to the RX-DP20VBK. This allows listeners in different rooms to listen to different audio sources at the same time. The new receiver also features seven independent 120-watt amplifiers and an independent Direct Power Supply with separate analog and digital transformers.

The TMS320DA610, which is part of TI's AureusTM family of audio DSPs, is a 225 MegaHertz (MHz) floating point DSP that delivers 1800 million instructions per second (MIPS) and 32/64-bit native processing. This high performance is critical to the delivery of next-generation digital audio features because it enables OEMs to add proprietary audio processing algorithms to their system even while decoding the most demanding standards. The DA610 also features an open audio framework that gives manufacturers a flexible environment in which to easily add the features that will differentiate their products and help them win their markets.

"Working with the flexibility and performance of TI's 32/64 audio DSP, we can deliver the next generation of audio features and realism to our customers," said Karl Bearnarth, vice president of JVC. "We can take advantage of the Aureus chip's headroom to add our own differentiating algorithms on top of those that are vital but don't necessarily set us apart from the competition."

"JVC is a leader in the audio world dedicated to delivering the ultimate listening experience to its customers," said Curt Moore, business manager of performance audio at TI. "By taking advantage of the performance of the Aureus family of products, they will be able to redefine that experience with incredible digital sound and new enhancements."

Consumers are demanding life-like sound quality and more features in their home entertainment products. To deliver this, manufacturers need to offer more channels, a higher sampling rate, arithmetic precision and a breadth of multi-channel digital audio formats. To succeed, they must have access to silicon and software that deliver higher performance, greater flexibility and facilitate the differentiation of products. Only TI's Aureus audio DSPs address these needs.

The Aureus platform is based on the proven silicon and tools of the code-compatible TMS320C6000TM DSP platform, featuring peripherals such as a 32-bit EMIF, two I2C ports and a 16 channel EDMA. The DA610 also features two new multi-channel audio serial ports (McASP) that allow up to 16 stereo channels of IS per port. These ports are also compatible with the S/PDIF standard. These highly integrated technologies are seamlessly combined with an audio software framework that is accessible through TI's easy-to-use Code Composer StudioTM Development Tools. With this difficult integration already completed, manufacturers can dedicate their engineering time and dollars to adding features that differentiate their products and get them to market more quickly.

The JVC RX-DP20VBK A/V receiver is expected to be available in January of 2003 at a Nationally Advertised Value of $2,500.
