Abstract
A game computer system for processing sound data and image data in synchronization with each other is disclosed.
An adaptive difference pulse code modulator (ADPCM) is used to produce high quality sound in synchronization with a horizontal synchronization signal, which is also used for controlling the display cycle of image data, for eliminating time gaps between the displayed image and transmitted sound. The game computer system quickly recovers from interruptions during sound reproduction, and resumes from the point of interruption through the use of pre-calculated, or virtual, sound data to maintain continuous transmission of sound. Because the sampling frequency can be decreased from the optimum frequency as required, the computer system performs linear interpolation upon the sound data to ensure high quality sound reproduction at the lower sampling frequencies. By performing a rounding function upon the data, the ADPCM decoder accurately reproduces sound data resulting in high quality sound reproduction at all times.
