ABSTRACT:
A picture reproducing apparatus includes a CD-ROM drive for fetching compressed video image data from a disc on which initial I-picture data for an initial picture for a menu display and a plurality of updating P-picture data for partially updating the initial picture are recorded. The picture reproducing apparatus also includes a RAN having a capacity of at least one video image frame and having an updating picture data storage area, an MPEG decoder for decoding MPEG encoded picture data and a CPU for initially transmitting the initial picture data and subsequently transmitting the updating picture data to the decoder. By making a picture display for displaying menu items or the like with the aid of a compressed picture decoder as used for displaying the compressed moving picture or still picture, the menu items or the like may be displayed without employing a graphic display circuit.
