Complex optical disc player system reproducing optical discs having various formats

An optical disc player system having a digital signal processor for processing a data signal having a data format read from an optical disc and reproducing the optical disc, the optical disc player system comprising:

• a plurality of decoders which decodes data of different formats, the data output from the digital signal processor;
• a data output unit which selects one of the data output from the digital signal processor and a decoded data output from the decoders, converts the selected data into an analog signal, and outputs the converted signal to a corresponding channel;
• a controller which enables one of the decoders depending on the data format of the data signal and controls the selection operation of the data output unit;
• an interface circuit which receives a predetermined data from an external host computer and sends the predetermined data to one of the plurality of decoders;
• and
• a buffer memory which stores the data output from the plurality of decoders depending on one of the data format of the data signal and an operation mode of the optical disc, and outputting a stored data to the decoders.

A method for processing data signal read from an optical disc having a format and reproducing the optical disc, comprising the steps of:

• decoding data having the formats, the data output from a digital signal processor;
• selecting one of the data output from the digital signal processor and a decoded data output from a decoder;
• converting the selected data into an analog signal;
• outputting the converted signal to a corresponding channel;
• enabling a decoder depending on the format of the data signal;
• storing the data output from the decoder depending on one of the data format and an operation mode of the optical disc;
• and
• outputting a stored data to a data output unit.
