DIGITAL VIDEO DISK PLAYER AND REPRODUCTION CONTROL METHOD THEREOF

摘要

IN AN OPTICAL DISK PLAYBACK CONTROL DEVICE, A SIGNAL REPRODUCING PORTION CONTROLS A SERVO OF A DIGITAL VIDEO DISK AND REPRODUCES A SIGNAL. A DATA PROCESSOR DEMODULATES AND ERROR-CORRECTS DATA GENERATED FROM THE SIGNAL REPRODUCING PORTION AND PROCESSES THE ERROR-CORRECTED DATA ACCORDING TO PLAYBACK CONTROL INFORMATION. A DECODER GENERATES AND OUTPUTS AUDIO AND VIDEO DATA BY DECODING THE DATA IN THE DATA PROCESSOR. A SYSTEM CONTROLLER RECEIVES A USER'S KEY INPUT SIGNAL AND APPLYS A CONTROL SIGNAL TO THE SIGNAL REPRODUCING PORTION TO REPRODUCE THE DATA ON A DISK, AND APPLYS REPRODUCTION CONTROL TO THE DATA PROCESSOR AND THE DECODER. A STORAGE HAS A FIRST STORAGE AREA WHICH IS USED FOR DEMODULATION AND ERROR CORRECTION BY THE DATA PROCESSOR, A SECOND STORAGE AREA FOR STORING DATA DEMODULATED AND ERROR-CORRECTED IN THE FIRST STORAGE AREA AND A THIRD STORAGE AREA FOR STORING PLAYBACK CONTROL INFORMATION WHICH CONTROLS THE DATA OF THE SECOND STORAGE AREA, SO THAT THE PLAYBACK CONTROL INFORMATION OF THE THIRD STORAGE AREA IS READ AND WRITTEN BY THE SYSTEM CONTROLLER.
