1 General Description

STV82x8

This chip performs BTSC stereo and SAP analog TV stereo sound identification and

demodulation (no specific I²C programming is required). It offers various audio processing

functions such as equalization, loudness, beeper, volume, balance, and surround effects. It provides

a cost-effective solution for analog and digital TV designs.

The STV82x8 is an audio processor which integrates SRS® WOW™, SRS® TruSurround XT™,

Dolby® Pro Logic®, Dolby® Pro Logic II®, Virtual Dolby® Surround (VDS) and Virtual

Dolby® Digital (VDD) capabilities.

Advanced ST royalty-free algorithms such as ST OmniSurround, ST WideSurround, ST Dynamic

Bass, ST Bass Enhancer are also available in this audio sound processor. ST OmniSurround is a

certified Dolby® algorithm for the Virtual Dolby® Digital (VDD) and the Virtual Dolby® Surround

(VDS). When using VDD or VDS, either an external Dolby® Digital or an internal Pro Logic® (or

Pro Logic II®) decoder must be used respectively.

The STV82x8 is perfectly suited to current and future digital TV platforms, based on audio/video

digital chips (STD2000 - DTV100 platform) which include an internal digital decoder (MPEG,

Dolby® Digital...). In the case where a Dolby® Digital decoder is embedded in the audio/video

digital chip, Virtual Dolby® Digital certification could be obtained.
