Abstract
Abstract Images of reproduced video data of plural channels are displayed on main small screens arrayed in a central horizontal row on an index picture. Time-serially anterior images of reproduced video data are displayed on two upper small screens above the main small screens, while time-serially posterior images of reproduced video data are displayed on two lower small screens below the main small screens. In a forward reproduction mode, the images displayed on the respective small screens are altered, with a lapse of time, to the lower adjacent images while being cross faded. And in a reverse reproduction mode, the images are altered, with a lapse of time, to the upper adjacent images while being cross faded. A normal reproducing operation is started from a desired image when the main small screen, where the desired image is being displayed, is selected by means of a cursor. Thus, any image of video data can be indexed efficiently.
