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.
