摘要： In order to provided information for helping a viewing user remember the contents of past viewing of a video program, in an easy-to-comprehend form and in as small an information amount as possible, a video terminal device capable of controlling video playback by a controller stores a position of the video program at which it was interrupted by the user. The interrupted position is stored in a video library of a video server. Images representative of a portion from the start or another position of the interrupted video program up to the interrupted position are extracted by a video digest making program. The extracted representative images are represented by a list display based on reduced icons or a digest image. The list or the digest image is displayed before resuming the interrupted video program.

摘要： A system for detecting a point of change between video shots from a video having a plurality of succeeding frames. The system includes video playback apparatus for playing a video chronologically one frame at a time, and a display for displaying the video. The a processing device for calculating a feature quantity of video image data for each frame, determining a first correlation coefficient between a feature quantity of a current frame and a feature quantity calculated from an immediately preceding frame and determining a second correlation coefficient between the feature quantity of the current frame and a feature quantity of at least two frames preceding the current frame, and indicating on the display a point of change between video shots when the first correlation coefficient and the second correlation coefficient are out of predetermined allowable ranges. The correlation coefficients of each frame is stored and can be used by the processing device to dynamically change a reference used for detecting a point of change between video shots. The change in the reference is performed based on the stored correlation coefficients or feature quantities of past frames.
