Optical disc player
First Claim
1. An optical disc player, comprising:
- an optical pickup unit;
a signal processor for extracting streams from a signal read by said optical pickup unit;
a demultiplexer for dividing streams received from said signal processor into sub-streams for every data;
an audio decoder for decoding audio data received from said demultiplexer;
a video decoder for decoding video data received from said demultiplexer;
an On-Screen-Display (OSD) processor for processing OSD data received from said demultiplexer;
a data output unit for outputting data processed at said audio decoder, said video decoder, and said OSD processor; and
a controller for controlling overall operations of said optical disc player, wherein said controller, upon receiving a contents view request from a user, reads a meta data file and displays images, and wherein the meta data file comprises an MPEG still image.

Abstract
An optical disc player includes an optical pickup unit; a signal processor for extracting streams from a signal read by the optical pickup unit, a demultiplexer for dividing streams received from the signal processor into sub-streams for every data, an audio decoder for decoding audio data received from the demultiplexer, a video decoder for decoding video data received from the demultiplexer, an OSD (On-Screen-Display) processor for processing OSD data received from the demultiplexer, a data output unit for outputting resultant data processed at the audio decoder, the video decoder, and the OSD processor, and a controller for controlling overall operations of the aforesaid components. The controller executes an application program upon receiving a contents view request signal from a user, reads meta data files needed for controlling playback of contents upon receiving a control signal of the application program and a user'"'"'s request signal, gains access to MPEG still images needed for playback of media data contained in the meta data files upon receiving access information associated with media data of the meta data files, outputs resultant images to the video decoder, and outputs graphic data to the OSD processor.
