Advanced TDMA technology to boost cable bandwidth
Texas Instruments has unveiled its new technology featuring end-to-end advanced TDMA that will enable a 50% increase in upstream plant capacity.
All the receivers are XM satellite radio ready, with the purchase of an optional XM connect-and-play antenna.
This will be one of the first times consumers can experience neural surround, which enhances the XM HD surround broadcast among other audio sources, by implementing matrix decoding to split the signal to all five speakers for a surround sound effect.
Additional features that TI enables in all three receivers include: Cinema DSP - creates deep and wide sound fields with precise imaging and sound clarity, bringing a realistic ambience to all sound sources; Compressed Music Enhancer - improves the listening experience of audio being played back from an iPod or other portable music player by restoring the rich sound quality removed in the encoding/ripping process Night Listening Enhancer - suppresses the loud passages typically heard during action scenes and enhances dialogue and quiet passages to sustain a consistent listening experience that will not disturb others; and Virtual Cinema DSP and Silent Cinema - creates realistic 5.1 channel surround sound without rear surround speakers or for use with headphones.
The RX-V559 and RX-V659 are able to support an iPod docking station, YDS-10, sold separately.
This enables the receivers to control the content of the iPod through the receiver's remote with on-screen display (OSD) information on the TV.
Coupled with Yamaha's Compressed Music Enhancer algorithm, compressed audio playback achieves a rich home theatre experience.
In addition, in the RX-V659, the Aureus DSP enables Yamaha's Parametric Room Acoustic Optimiser (YPAO) room correction technology, which automatically optimises the sound for any home theatre.
"Yamaha continues to utilise the latest in DSP technology to drive innovation in the audio/video receiver market", said Akihiro Muramatsu, Department Manager of Products Development department in AV Products division, Yamaha.
"We have developed the new Cinema DSP Engine based on the Aureus DA7xx DSP because the high performance, ease of adding differentiating features and great support enabled us to create, design and customise receivers quickly to get feature-rich products out ahead of our competitors".
"Yamaha's AVRs are a great example of the robust features that can be enabled in the low-cost home theatre market using TI's Aureus DSPs", said Dave Maples, Performance Audio Business Manager, TI.
"In a short period of time, TI provided Yamaha the proven tools they needed to easily speed up time to market and simplify development".
"We look forward to continuing our strong relationship with Yamaha in the future".
TI's Aureus product line consists of a 32/64bit floating-point programmable DSP and a comprehensive software solution, enabling multi-channel decoding applications.
With the DSPs, an optimised software solution of certified, industry-standard decoders and postprocessors is provided, producing performance headroom for substantial customisation through high-performance proprietary audio processing algorithms.
TI's Aureus product line was recently named "Best DSP for Audio" in the 2005 In-Stat MPR Analysts' Choice Awards and the Aureus DA710 DSP is an EDN 2005 "Innovation of the Year Award" finalist in the ASSPs and SOCs category.
All the new Yamaha AVRs are expected to be available by the end of March in the USA and in select regions around the world, with suggested retail prices ranging from US $349 to $549.
