A PRE-VIEWING METHOD OF MULTIPLE MOVIES OR MOVIE-CLIPS IN MULTIMEDIA APPARATUS

摘要

A method for previewing a plurality of moving images in various multimedia playing devices, simultaneously and in real-time, is disclosed. The method is performed in a multimedia device which includes one or more than one video decoder (VD) for decoding a plurality of moving images (M1, M2, M3, MN) to be previewed, in which the video decoder (VD) outputs a video picture (P) generated as a video processor (VPC) processes decoded signals. More specifically, the method comprises the steps of: allocating extraction interval (d) of I-frame from respective groups of pictures (GOP) of respective moving images (Ma, Mb, Mb, Mm) to extract preview images from the respective moving images (Ma, Mb, Mb, Mm) and extracting the I-frame in the GOP of the moving images (Ma, Mb, Bb, Mm) with the extraction interval (d) of the I-frame (I), decoding the extracted I-frame, and outputting the decoded I-frame on an output display. Therefore, the method previews a plurality of moving images in various multimedia devices using only a low performance processor or a single video decoder in real time, such that the multimedia device employing the method can be cost-effective and provide users with convenience of use.
