Abstract
A portable CD-MP3 system and a file system decoding method of operating the same utilize a high-performance DSP to decode an audio file in analyzing a file system. The DSP stores data regarding the file system information in a right-channel region of a memory unit if the analyzed file system information represents the title of an audio file, and stores the data in a left-channel region of the memory unit for navigation of the audio file if the analyzed file system information does not represent the title of the audio file.
Claims16
A portable CD-MP3 system comprising:
- an audio reproduction unit for decoding an audio file and analyzing file system data of the audio file;
- a memory unit for storing information related to the decoded audio file and the analyzed file system data;
- and
- a system controller for selecting an audio file based on the stored information and for controlling the decoding of the audio file by the audio reproduction unit, to reproduce the selected audio file.
A file system decoding method for operating a portable CD-MP3 system, the file system decoding method comprising:
- (a) receiving MSF information of a CD frame and analyzing file system information based on the MSF data;
- (b) storing data regarding the analyzed file system information in an R-CH region of a memory unit if the analyzed file system information represents the title of an audio file;
- and
- (c) storing data regarding the analyzed file system information in an L-CH region of the memory unit for navigation of the audio file if the analyzed file system information does not represent the title of an audio file.
