APPARATUS FOR PROCESSING IMAGES AND METHOD THEREOF

摘要

An apparatus for processing images includes a de-multiplexer, a first decoder, a thumbnail generator and an encoder. The de-multiplexer receives a data stream, the de-multiplexer de-multiplexing a video signal and a channel information from the data stream. A first decoder decodes the video signal to provide a decoded video signal including at least one of Predicted frame, (P-frame), Intra frame (I-frame) or Bi-directional frame (B-frame). The thumbnail generator is coupled to the first decoder, and the thumbnail generator generates at least one of a still picture thumbnail or a moving picture thumbnail based on the decoded video signal. The still picture thumbnail and the moving picture thumbnail have at least one of a smaller resolution or a smaller data size than the decoded video signal. The encoder is coupled to the thumbnail generator and the de-multiplexer. The encoder encodes one of still picture thumbnail and the moving picture thumbnail with the channel information to provide a thumbnail data stream, which is used for providing the thumbnails of moving picture and/or still picture on a display.
