The invention relates to a device and a method for recording data on a recording medium. The invention relates to the implementation of the timeshift function in a part of said recording medium called the timeshift buffer memory having a size defined in terms of recording capacity. For the timeshift buffer memory, a first threshold defines a capacity limit, a second threshold defines a recording time limit. The device records the data in the timeshift buffer memory as long as the second threshold is not reached and when the second threshold is reached before the first threshold, the processor truncates the start of the timeshift buffer memory when the data being read are not located at the start of the buffer memory or moves to reading the data of the timeshift buffer memory when the data being read are located at the start of the timeshift buffer memory.

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 () 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 () into which the demodulated input signal (SD) is diverted when the decoder is placed in the &#x201c;playback&#x201d; mode, the signal recorded in the second buffer memory () constituting the output signal when the decoder is switched from the &#x201c;playback&#x201d; mode to another so-called &#x201c;return to live&#x201d; mode of operation. In the &#x201c;return to live&#x201d; mode, the user views at high speed the video portion recorded in the second buffer memory before the decoder switches back to the &#x201c;live&#x201d; mode.
