Abstract
The present invention enables to obtain a video representation with a smooth motion during a fast reproduction of a video signal which has been prediction coded in the time axis direction. A video signal reproduction apparatus includes a controller having a detection block , a decision block , and mode switching block . According to an information from a demultiplexer and a decode information from a video decoder , the controller detects a reproduction speed in the detection block . The detected reproduction speed is supplied to the decision block where it is compared to a predetermined threshold value so as to select a first fast reproduction mode requiring reproduction of all the reference pictures of the video signal which has been prediction coded or a second fast reproduction mode requiring reproduction of some the reference pictures. According to this decision result, the mode switching block switches between the first and the second rast reproduction modes.
