ABSTRACT:
A method and apparatus are provided for transmitting dummy video sync and audio signals in an optical disc player, which are capable of generating a dummy video sync signal when the optical disc player plays an audio-only optical disc. The method and apparatus transmit to a television the dummy video sync signal along with an audio signal read/reproduced from the optical disc. Accordingly, the invention prevents the television from being automatically turned off or switched to an audio mute state when only audio signals are reproduced from the disc without any reproduction of associated video signals. As a result, the user can hear audio sound through speakers equipped in the television even though only audio signals are reproduced from the disc.
