ABSTRACT:
A video transcript retriever includes a control unit, a control interface, a tape unit and a display unit. The control unit includes a control computer having a software package consisting of control software, text software and edit software. The control software has the capacity to permit simultaneous operation of both the test software, which is capable of storing and searching voluminous documents, and the edit software, which has the capacity to operate the tape unit with precision. The text software is capable of performing a search function that at any time can provide the exact location of a specific passage within the searched document in terms of page and line. The edit software has the capacity to provide at any time the timecode number pre-recorded on the videotape that corresponds to a specific passage. The process for locating and retrieving specific information on a videotape includes the steps of striping the videotape by assigning a numerical address for every one-thirtieth (1/30) of a second segment of the videotape; indexing the words written in a computer transcript to the words spoken on the videotape by assigning a timecode number to both the computer transcript and the videotape segment where each question/answer passage begins; and instructing the tape unit to shuttle to a precise tape location determined by the timecode numerical address located during the search of the computer transcript.
