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

â 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).
