DDCE Required to enable DVD Recordable Products
(Company Press Release)

AUSTIN, Texas--August 24, 1999--Designing for the next generation DVD (digital versatile disk) recordable products is now possible using Motorola's DSP56362, which has been granted the Dolby® Digital Consumer Encoder (DDCE) certification by Dolby Laboratories. DVD-RAM, DVD-RW and DVD-camcorders, applications requiring the DDCE technology, may be available to consumers within the next year.

The DSP56362 is currently being used in a variety of consumer audio products, such as audio/video receivers and DVD, digital television and automotive applications. Motorola provides a comprehensive silicon and software solution in a single chip that provides multi-channel decoding (Dolby Digital, DTS or MPEG2 Layer 2) and post decoder processing. The DSP56362 now also supports DDCE. The Dolby Digital Consumer Encoder is a two-channel encoder technology, which enables the digital encoding of stereo analog sound for storage on a digital media. This enables a DVD-RW recorder, for example, to record conventional analog TV programming in addition to the new digital TV broadcasts.

``Many customers have indicated to Motorola that the DDCE has been the missing technology to fully enable recordable DVD products, and Motorola is pleased to provide the industry's first solution to meet these needs,'' said Valerie Hase, Operations Manager of Motorola's Digital Audio Operations. ``Motorola forecasts significant demand for this technology and, as a result, we are already in development on second generation DDCE solutions, which will eliminate external memory requirements. As a leader in high-performance programmable audio products, Motorola continues its commitment to the industry by expanding its audio library in both audio decoding and audio encoding.''

The DSP56362 was the first Symphony® audio DSP to utilize the DSP56300 core. With speeds up to 100 MIPS, the DSP56362 provides the capability to handle all the major multi-channel audio decoding standards as well as other audio processing requirements such as subwoofer management, soundfield effects, 3D virtual surrounds, equalization, Lucasfilm THX® Cinema processing and Pacific Microsonics HDCD.

Ramzi Haidamus, Technology/Business Strategist, Dolby Laboratories, said, ``Dolby developed their software reference design for DDCE based on Motorola's DSP56300 architecture and is cooperating closely with Motorola on further optimizations. Dolby is pleased to grant Motorola certification for the DSP56362 implementation of Dolby Digital Consumer Encoder and is working closely with Motorola on future versions.''

The DSP56362 is available now at authorized Motorola distributors. A comprehensive set of development tools is available for the DSP56362. Free DSP56300 assembler and simulator tools are downloadable from Motorola's Web site at Additional C compilers and debugging software tools are available from third parties.
