Abstract

See full text

A digital decoder for television receiver, comprises an input (E) for receiving a digital audio/video signal (SAV), means for demodulating and decoding the input signal into an output signal intended for the television receiver, and a first buffer memory (8) into which the input signal is diverted after demodulation (SD) when the decoder is placed in a so-called “live” mode of operation. In a so-called “playback” mode of operation, the signal recorded in the first buffer memory constitutes the output signal. This decoder comprises a second buffer memory (9) into which the demodulated input signal (SD) is diverted when the decoder is placed in the “playback” mode, the signal recorded in the second buffer memory (9) constituting the output signal when the decoder is switched from the “playback” mode to another so-called “return to live” mode of operation. In the “return to live” mode, the user views at high speed the video portion recorded in the second buffer memory before the decoder switches back to the “live” mode.
