TL;DR: In this article, an automatic authoring system for the generation of pictorial transcripts of video programs which are accompanied by closed caption information is presented, where a number of key frames, each of which represents the visual information in a segment of the video (i.e., a scene), are selected automatically by performing a content-based sampling of video program.
Abstract: An automatic authoring system for the generation of pictorial transcripts of video programs which are accompanied by closed caption information is presented. A number of key frames, each of which represents the visual information in a segment of the video (i.e., a scene), are selected automatically by performing a content-based sampling of the video program. The textual information is recovered from the closed caption signal and is initially segmented based on its implied temporal relationship with the video segments. The text segmentation boundaries are then adjusted, based on lexical analysis and/or caption control information, to account for synchronization errors due to possible delays in the detection of scene boundaries or the transmission of the caption information. The closed caption text is further refined through linguistic processing for conversion to lower- case with correct capitalization. The key frames and the related text generate a compact multimedia presentation of the contents of the video program which lends itself to efficient storage and transmission. This compact representation can be viewed on a computer screen, or used to generate the input to a commercial text processing package to generate a printed version of the program.

TL;DR: In this paper, a control program stored in a computer takes out a closed caption digital text stream relating to the segment immediately before of video first, and the text stream is transmitted to the computer 104 by a closed-caption decoder 103 and the received text is kept inside a storage device 105.
Abstract: PURPOSE: To improve the ability of controlling the contents of video presentation by a user by extracting and searching information carried by the closed caption part of television signals and finding a program interested in by a viewer. CONSTITUTION: A control program stored in a computer 104 takes out a closed caption digital text stream relating to the segment immediately before of video first. The text stream is transmitted to the computer 104 by a closed caption decoder 103 and the received text is kept inside a storage device 105. The control program decides whether or not the logged text stream matches with a specified search reference. Then, the control program identifies the segment of the television signals. Then, the viewer edits the television numbers.
