<p>A television signal receiver receives and stores television signals encoded at a variable data rate. Time information is generated based on the time of receipt of the signals that defines the duration of the television signals when output in decompressed form at a substantially constant data rate. The received signals are then written to a file on a hard disk (13) in received order together with the time information. The time information of signals stored in the file is monitored and old signals are deleted from the file such that the file stores signals corresponding to a predetermined period of time.</p>
