ABSTRACT:
The invention is directed to the provision of a moving image data playback method, and more particularly, an MPEG data playback method that can randomly access MPEG data stored at a VBR. The playback method comprises: storing in a table an average bit rate computed from time information at the beginning and end of stored moving image data; detecting and storing the time information and position information of randomly accessible picture groups one at the beginning of the moving image data and the other at the end thereof, and computing a picture group unit time from the number of frames between adjacent picture groups and storing the result in the table; computing a point to be accessed, based on the average bit rate and other information stored in the table; and starting playback from the computed point to be accessed, and storing in the table the time information and position information of the picture groups detected during the playback and the average bit rate between each picture group computed from the detected time information and position information.
