摘要： Only a video cut (containing a frame) designated by a user is automatically and correctly extracted directly from a video image under playing operation at high speed. A judgement is made as to whether or not the frame of the video image is designated by the user. When such a user designation is made, a detection is made of a change point in the video cut containing this designated frame (reverse playing direction, forward playing direction). Under such a condition that a frame image immediately before this change point is displayed, the playing operation of the video image is brought into a pause state. Accordingly, only the video cut desired by the user can be extracted during a single playing operation of the video image, and the video image can be edited in a high efficiency.

摘要翻译： 用户指定的视频剪辑（包含帧）只能在高速播放操作下直接从视频图像中直接提取。 判断视频图像的帧是否由用户指定。 当进行这样的用户指定时，检测包含该指定帧（反向播放方向，向前播放方向）的视频剪辑中的变化点。 在显示紧接在该变化点之前的帧图像的条件下，视频图像的播放操作进入暂停状态。 因此，可以在视频图像的单次播放操作期间仅提取用户期望的视频剪辑，并且可以高效率地编辑视频图像。

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.
