Description

The STV82x7 family, based on audio DSPs

(digital signal processors), performs high quality

and advanced dedicated digital audio

processing.The STV82x7 devices provide all of

the necessary resources for automatic detection

and demodulation of analog audio transmissions

for European and Asian terrestrial TV broadcasts.

Virtual or true, multi-channel capabilities and easy

digital links make them ideal for digital audio low

cost consumer applications. Starting from

enhanced stereo up to independent control of 5

loudspeakers and a subwoofer (5.1 channels), the

STV82x7 family offers standard and advanced

features plus sound enhancements, spatial and

virtual effects to enhance television viewer

comfort and entertainment.
