Although DSP powerhouse Texas Instruments is more of known as a wireless incumbent, its silicon products are fast making a foray into an important new segment of consumer electronics: digital audio. The company has showcased two significant design wins during the Consumer Electronics Show (CES) in Las Vegas.

Japanese consumer electronics giant Panasonic has chosen TI's TMS320DA105 DSP to bring digital audio in its new DVD player. The Panasonic DVD-RV32 will be the first ever player to support Windows Media Audio (WMA) file playback, allowing all kinds of digital content to be played on one single device.

"Adding audio to DVD applications extends to a number of markets including digital audio players, cellphones, PDAs, Internet appliances and home stereos," said Fred Cohen, worldwide manager of digital audio at TI.

In another development, OpenGlobe has built a reference design that utilizes a DSP-based solution from TI to enable Internet radio streaming of digital music files from a digital audio server appliance or a PC in a home network. The firm, specializing in technology solutions for home entertainment, claims that manufacturers will be able to offer networked audio receivers that support WMA and MP3 files for less than $199.

OpenGlobe chief executive Bernie Sepaniak said that the universal plug-and-play (UPnP) network audio reference design for entertainment receivers/players is using a variety of silicon solutions from TI including DSP, codecs and digital amplifiers.

The programmability of TI's network audio processors will allow OEMs to differentiate their products with home networking options such as Ethernet, HomePlug, HomePNA or 802.11b. The UPnP-compliant design plays WMA and MP3 music files, as well as Internet radio stations streamed in either format. The reference design and evaluation boards are expected to be available in March 2002.
