Abstract:
A method and apparatus for determining if there is a stream of video signals corresponding with a stream of audio signals. If the sample rate of a digital bitstream including is determined. if the sample rate is 48 m kHz (where m is an integer), it is determined that there are video signals corresponding to the audio signals. If the sample rate is 44.1 m kHz (where m is an integer), it is determined that there are no video signals corresponding to the audio signals.
