Optical disc reproducing apparatus

摘要

An optical disc reproducing apparatus reproduces different encoded audio signals from an optical disc (1) which comprises a first optical disc carrying recorded first audio data which is previously digitally converted by a non-compression-encoding or a second optical disc carrying recorded second audio data which is previously digitally converted by a compression-encoding. The optical disc reproducing apparatus has: an extracting circuit (3) for extracting the first and second audio data; an identifying circuit (8) for identifying the optical disc; a converting circuit (4) for converting the second audio data to digital data obtained by the non-compression-encoding; a designating circuit (9) for designating compression-encoded data in order to transmit; relay circuit (5) for selectively relaying outputs of the extracting circuit (3) and converting circuit (4) in accordance with an identification signal; a circuit (6) for converting the digital data which is generated from the relay circuit (5) to self-synchronous type data; and an output terminal (7) for supplying the self-synchronous type data to an external apparatus (not shown). When there is a designation from the designating circuit (9), the relay circuit (5) forcedly relays the output of the extracting circuit (3). <IMAGE>
