The video circuit for a satellite application consists of a voltage controlled AGC-amplifier, driver for
two external de-emphasis networks, followed by a three-stage switch. An additional baseband
output is available via a driver. The output signal of the video switch is applied to a video clamping
circuit, this clamping circuit removes the energy dispersal signal from the video signal. The clamped
signal is applied via a video switch to the SCART-output.
Circuit Description
The demodulated FM-satellite video signal is fed via a buffer amplifier to a gain controlled amplifier.
The gain control is done using an external applied DC-voltage. The output signal of this amplifier is
used to drive three separate signal pathes. First of all the baseband is fed via a high pass filter with
a cut off frequency of approx. 4 MHz to the input of a SAT-TV-sound processor, e.g. TDA 6160 X.
A second output with a buffer amplifier is used to drive two external de-emphasis networks. After
passing through the de-emphasis networks the baseband signals are fed into two inputs of the de-
