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.
