1 General Description

STV82x7

The STV82x7 is a multistandard TV sound demodulator and 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) capability.

ST advanced algorithms such as ST OmniSurround, ST WideSurround, ST Dynamic Bass 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 a Dolby® Digital or a Pro Logic® (or Pro Logic II®) decoder is mandatory

respectively.

This chip performs automatic multistandard 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 STV82x7 is perfectly suited to current and future digital TV platforms, based on audio/video

digital chips (STD2000, (DTV100 platform) and the future WorldWide iDTV one chip) 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 could be obtained.

For the CTV100/120 platform, the device is offered as an alternative solution to the first-generation

chassis that uses the STV82x6.
