Abstract
A digital video multiplex processing method comprises the following steps: setting a normal play index and a fast play index; performing a normal recording/playback action of a video data; determining whether to let the video data enter a cue-and-jump action; taking track of the fast play index in the video data; performing conversion of the video data; and setting the normal play index to be equal to the fast play index. A digital video multiplex processing device comprises a video medium readout unit, a drive interface unit, a data regulation unit, a data buffer unit, an image decoding unit, a sound decoding unit, an image processing unit, a sound processing unit, and a control unit. The control unit is used to receive operation instructions of a user to control the operation of the digital video multiplex processing device.
