Abstract:

A method and apparatus for retrieving different types of content through one or more audio output connectors of an audio CD player is described. In one embodiment of the invention, data carried in Redbook-encoded format is optically read from a CD. The data carried in Redbook-encoded format is Redbook-decoded into data representing converted content of a certain type, which was converted from input data of the same type. The data representing converted content is transmitted out of a CD player device through one or more analog output connectors. In a separate outgoing conversion device detachably coupled with the analog output connectors, the data carried in Redbook-unencoded format is demodulated. The data representing converted content is converted into currently playable reconstructed data approximately representing the input content. The input content may be input video content, input audio content sampled at a higher sampling frequency than a sampling frequency allowed by Redbook-encoded format, input audio content sampled with a larger word length than a word length allowed by Redbook-encoded format, etc.
