· Linear and non-linear horizontal scaling of the video signal to be displayed.
Sound Demodulation (all versions)
· Separate SIF (Sound IF) input for single reference QSS (Quasi Split Sound) demodulation.
· AM demodulator without extra reference circuit
· The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched
to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such
that the external band-pass filters can be omitted. In the stereo versions of UOCIII the use of this
demodulator is optional for special applications. Normally the FM demodulators of the stereo
demodulator/decoder part are used (see below).
· The FM-PLL demodulator can be set to centre frequencies of 4.72/5.74 MHz so that a second
sound channel can be demodulated. In such an application it is necessary that an external
bandpass filter is inserted.
· The vision IF and mono intercarrier sound circuit can be used for the demodulation of FM radio
signals. With an external FM tuner also signals with an IF frequency of 10.7 MHz can be
demodulated.
· Switch to select between 2nd SIF from QSS demodulation or external FM (SSIF)
Audio Interfaces and switching (stereo versions with Audio DSP)
· Audio switch circuit with 4 stereo inputs, a stereo output for SCART/CINCH, 1 stereo output for
HEADPHONE. The headphone channel has an analogue volume control circuit for the L and R
channel. Finally 1 stereo SPEAKER output with digital controls.

· Digital input crossbar switch for all digital signal sources and destinations
· Digital output crossbar for exchange of channel processing functionality
· Digital audio input interface (stereo I2S input interface)
· Digital audio output interface (stereo I2S output interface)
Audio interfaces and switching (AV stereo versions without Audio DSP)
