Edited by the Electronicstalk editorial team Feb 13, 2006

On show at 3GSM in Barcelona, Seiko Epson's latest audio decoder chip, the S1V30220, includes MPEG-4 aacPlus v2 decoding for mobile phones and portable media players.

Seiko Epson will demonstrate its latest audio decoder chip S1V30220 at the 3GSM World Congress in Barcelona, including MPEG-4 aacPlus v2 (Enhanced aacPlus) decoding, targeted for mobile phones and portable media players.

Being the most efficient audio codec available and the 3GPP standard for high quality music delivery, aacPlus v2 has been adopted as the music codec of choice by most network operators world wide.

Due to its high compression efficiency, aacPlus v2 enables the market of mobile music and saves consumers from carrying multiple devices by facilitating the convergence of portable music players and mobile phones.

The use of the S1V30220 chip allows handset manufacturers to easily integrate the aacPlus v2 codec into their products.

The S1V30220 is a single chip, low-power solution for decoding aacPlus, AAC, MP3 and MIDI content, and includes integrated post-processing functions such as loudspeaker equalisation, digital volume control and stereo to mono down mix.

Decoder applications are controlled over a single serial interface (SPI), allowing control from a wide range of host devices and rapid integration into end products.

The chip also includes an MMC/SD Card interface and FAT file system, allowing stand-alone audio decoding without host-processor intervention.

A complete PC-based development/evaluation kit is available.

"Mobile music will drive 3G data revenues, and the operators are eager to offer these services to their customers", says Dr David Crawford, Manager Epson Scotland Design Centre.

"aacPlus v2 is the enabling technology, and we are happy to provide a solution for this promising business field".

"Epson's S1V30220 is a straightforward and trend-setting solution to quickly and easily bring aacPlus v2 into affordable end products", says Stefan Meltzer, Vice President Business Development, Coding Technologies.

"This chip impressively demonstrates Epson's expertise in the mobile consumer field, and we are thrilled to see it being exhibited at 3GSM World Congress".

Epson's S1V30220 can be seen on Epson's booth G111 in Hall 2, at the 3GSM World Congress.
