MCG DATA FILE GENERATING AND REPRODUCING METHOD AND MEDIA WHERE FILE THEREOF IS CONTAINED AND REPRODUCTION DEVICE OF FILE THEREOF, CONCERNED WITH COMPRESSING SPACE WHILE DESIGNATING DESIRED SCREEN SIZE AND DESIRED RESOLUTION

摘要

PURPOSE: An MCG(Multimedia Compact Graphic) data file generating and reproducing method is provided to include necessary data only for displaying graphics in a generated file, and to optionally designate a data processing speed per second, thereby compressing a space while designating a desired screen size and desired resolution. CONSTITUTION: A system retrieves graphic data from a subcode channel of a disk to extract the retrieved graphic data, and retrieves/extracts audio data from a main channel(210). The extracted data is stored in a temporary memory. The system integrates the graphic data with the audio data, and generates one image file(230). The system extracts the graphic data only from the generated image file, and converts it into an MCG data format file(250). The system separately compresses an audio file only of the image file, and generates an MP3 format audio file(270).
