1 General Description
General Description
1.1 Overview
The STV82x6 is composed of three main parts:
1. TV Sound Demodulator: provides all the necessary circuitry for the demodulation of audio
transmissions of European and Asian terrestrial TV broadcasts. The various transmission
standards are automatically detected and demodulated without user intervention.
2. Audio Processor: based on DSP technology, independently controls loudspeaker, subwoofer
and headphone signals. It offers basic and advanced features, such as a ST WideSurround,
Equalizer, Automatic Loudness and Smart Volume Control for television viewer comfort. The
STV8226/36 versions can perform additionally the SRS® 3D Surround for stereo and mono
signals.

3. Audio Matrix: 3 stereo and 1 mono external analog audio inputs to loudspeakers and
headphone, with 2 stereo external analog audio outputs (SCART compatible).
