Abstract
A receiver for receiving an MPEG encrypted transport stream and outputting audio and video signals comprising: a decryptor adapted to receive and decrypt the encrypted transport stream; a de-multiplexer adapted to convert the decrypted transport stream to audio and video elementary streams and to change the values in presentation time stamp and decoding time stamp fields of each packet of the audio and elementary streams to match the time of a receiver record clock; a storage sub-system adapted to store the audio and the video elementary streams and to change the values in the presentation time stamp and decoding time stamp fields of each header of the audio and video elementary streams to compensate for the amount of time the audio and video elementary streams are stored; and audio and video decoders to decode the audio and video elementary streams respectively.
