Abstract
A television presentation and editing system uses closed captioning text to locate items of interest. A closed captioning decoder extracts a closed captioning digital text stream from a television signal. A viewer specifies one or more keywords to be used as search parameters. A digital processor executing a control program scans the closed captioning digital text stream for words or phrases matching the search parameters. The corresponding segment of the television broadcast may then be displayed, edited or saved. In one mode of operation, the television presentation system may be used to scan one or more television channels unattended, and save items which may be of interest to the viewer. In another mode of operation, the system may be used to assist editing previously stored video by quickly locating segments of interest.
