Abstract
Provided are a method and apparatus for normal reverse playback of GOPs of a bitstream stored in a storage medium from an XGOP. The apparatus includes an MPEG decoder which reads a first bitstream corresponding to the XGOP and an (X−1)GOP from the storage medium and which decodes pictures of the XGOP and reference pictures of the (X−1)GOP using the read bitstream, a frame buffer which stores the pictures decoded by the MPEG decoder, and a display block which displays the decoded pictures stored in the frame buffer, wherein during the normal reverse playback, the apparatus displays all the decoded pictures only once, and each display time of the decoded pictures displayed only once is the same. Accordingly, the apparatus can perform a linear search even during the normal reverse playback.
