Abstract
In the skip reproduction from a frame X in a first access unit (XGOP) to a frame Y in a second access unit (YGOP), a reproduction method stores a front data and the data onward YGOP while display of frame X is maintained. Then, a front frame (I-picture) and onward is decoded and displayed in YGOP. Another reproduction method decodes the front frame (I-picture) to the frame Y in YGOP, and keeps on displaying the frame X instead of displaying the decoded frames until the frame Y is decoded. At the time when the frame Y is decoded, display of the coded frames starts. A further reproduction method does not decode the bi-directionally predictive coded frames between the front frame and the frame Y in YGOP. These respective methods can improve accuracy of a reproduced motion in the skip reproduction and reduce a freezing time of displaying a picture from which the skip starts.
