Abstract
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.
