Abstract
A data synchronizing apparatus and method thereof capable of readily synchronizing video data and audio data by using a read pointer and a write pointer in each memory device storing the video and the audio data, includes a host processor for extracting video data, an information value indicating a start time of video data display and a system clock signal, and storing the extracted video data at a first data storing unit; and a video encoder for controlling a decoding speed of the video data read from a second data storing unit in accordance with a read pointer value of the second data storing unit when reading and decoding a write pointer value of the second data storing unit indicating an area where the extracted video data is to be stored and a video data previously stored at the second data storing unit.
