    • 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.
    • 用于处理图像的装置包括解复用器,第一解码器,缩略图生成器和编码器。 解复用器接收数据流,解复用器从数据流解复用视频信号和信道信息。 第一解码器解码视频信号以提供包括预测帧,(P帧),帧内(I帧)或双向帧(B帧)中的至少一个的解码视频信号。 缩略图生成器耦合到第一解码器,并且缩略图生成器基于解码的视频信号生成静止图像缩略图或运动图像缩略图中的至少一个。 静止图像缩略图和运动图像缩略图具有比解码的视频信号更小的分辨率或更小的数据大小中的至少一个。 编码器耦合到缩略图生成器和去多路复用器。 编码器利用频道信息对静止图像缩略图和运动图像缩略图中的一个进行编码以提供缩略图数据流,其用于在显示器上提供运动图像和/或静止图像的缩略图。
