The proposed digital device for processing signals for a television set with a liquid-crystal screen contains demodulators, a switching unit, a decoder, an analog signal processor, an analog-to-digital converter, and a microprocessor control unit. The outputs of the demodulators are connected to the corresponding inputs of the switching unit. The output of the switching unit is connected to the input of the coder. The output of the analog signal processor is connected to the input of the analog-to-digital converter. The output of the coder and the output of the analog-to-digital converter are connected to the corresponding inputs of the switching unit.
