Abstract
A video disk player includes (i) a disk reading section for reading out video data, a program, synchronization timing information from an optical disk; (ii) a clock for generating a clock signal; (iii) a decoder for converting, in accordance with the clock signal, the video data into decompressed video data for reproduction output; (iv) a video reproducing section including a synchronization control section for transmitting, in accordance with the clock signal, a synchronization control signal to the program executing section at a timing specified by a field timing contained in the synchronization timing information, and (v) a program executing section for executing a program in accordance with the synchronization control signal received from the synchronization control section. This makes it possible to efficiently execute the program in synchronization with reproduction of AV data or the like.
