A method of processing a compressed digital video bitstream wherein the bitstream is received and is transcoded to a bitstream having a different bit rate reflecting the storage mode selected by a user. The storage modes available may include long play (having a lower bit rate than the received bitstream), compress-to-fit (having a bit rate reflecting available storage space) and rapid access (having an increased bit rate , with P frames being recoded as I frames to allow high speed searching). The transcoding may include the steps of decoding the received signal, extracting the coding decisions and recoding using the extracted decisions. |
