Abstract

The decoder (3) has a processor (33) for implementing a time shift function in a part of recording medium i.e. time shift buffer memory (32). The processor includes a transcoding unit to transcode the received data to reduce quantity of data to be recorded before recording the data in the buffer memory. A detection unit detects that the buffer memory has reached a filling level greater than a preset threshold value. The transcoding unit transcodes the data only when the threshold value is exceeded and when flow of the data t is greater than a determined flow. An independent claim is also included for a method for receiving and recording audio video data on a recording medium.
