ABSTRACT:
A video decoding device which enables smooth reverse playback of 3:2 pulldown video streams. A video data storage unit stores pictures constituting a video stream that is being played back, where each picture consists of a first field and a second field. An attribute data storage unit stores attribute data which describes how each picture should be displayed. The attribute data includes a repeat-first-field flag for each picture. When playing back the video stream in a reverse direction, a reverse playback unit determines whether the repeat-first-field flag is set or cleared, and reads out the first and second fields of each picture in the same order as that in forward playback mode if the repeat-first-field flag is set. If the repeat-first-field flag is cleared, it reads out the first and second fields in the opposite order to that in the forward playback mode.
