Optical disc reproducing apparatus

An optical disc reproducing apparatus having a capability of reproducing different encoded audio signals from a first optical disc carrying recorded first audio data which is previously digitally converted by a non-compression-encoding and a second optical disc carrying recorded second audio data which is previously digitally converted by a compression-encoding, comprising:

• data extracting means for extracting said first audio data from said first optical disc and extracting said second audio data from said second optical disc;
• disc identifying means for identifying said first and second optical discs and generating an identification signal;
• coding-converting means for converting said second audio data extracted by said data extracting means to digital data by the non-compression-encoding;
• transmission data designating means for designating digital data to be transmitted to digital data by the compression-encoding;
• relay means for selectively relaying and generating an output of said data extracting means and an output of said coding-converting means in accordance with said identification signal;
• synchronized data converting means for converting the digital data which is generated from said relay means to self-synchronous type data;
• and
• an output terminal to generate said self-synchronous type data to an external apparatus, wherein when said disc identification signal indicates said second optical disc and there is a designation from said designating means, said relay means forcedly relays and generates the output of said data extracting means.
