摘要： The present invention relates to a system for scene change detection including a decoder decoding input digital video data into video data compressed by a single codec or uncompressed video data in a codec-independent format, a normalizer normalizing the video data decoded by the decoder in a temporally and spatially uniform format, and a scene change detector computing a mode ratio for each frame of the normalized video data through a mode determination, and determining, when a frame has a mode ratio higher than a preset threshold value, that a scene change has occurred at the frame. The decoder decodes video data compression-coded by various video codecs into uncompressed video frames.
