发明名称 Dual buffer cache system for transferring audio compact disk subchannel information to a computer
摘要 A method and apparatus are provided for displaying graphical information concurrent with associated audio information within a multimedia computer system. The graphical information (CD+G) and the audio information, is read from a compact disk by a compact disk reader, and decoded by a digital signal processor. The graphical information is stored temporarily in a cache buffer within the compact disk reader and then transferred from the cache buffer to a host computer for display. While the compact disk reader plays the audio, the graphical information is transferred to the host computer for display within the multimedia system.
