摘要

The present patent application relates to a video signal playback apparatus comprising video signal chunking means for partitioning a video signal provided to the video signal playback apparatus into video chunks, each video chunk comprising a first temporal amount of video signals, and video chunk compressing means for temporarily compressing the first temporal amount of video signals comprised in each video chunk. According to the present invention the video chunk compressing means temporarily compresses the first temporal amount of video signals comprised in each video chunk by automatically generating a key video sequence for each video chunk by using the video signals comprised in the respective video chunk, each key video sequence comprising a second temporal amount of video signals which is less than the first temporal amount of video signals, wherein the video signal playback apparatus further comprises key video sequence playback means for playing back said key video sequences generated by the video chunk compressing means.
