Abstract
A system and method of determining representative frames of a video sequence to form a visual table of contents for a video tape is disclosed. A representative frame is identified on the occurrence of an event, such as the beginning of a recording sequence, which may follow a record command, a pause-release command, some form of special effect command, or a user-initiated marking command. The representative frame, and location data associated therewith, may be marked along the length of a video tape in a camcorder or VCR, or, the representative frame may be identified and stored, along with the location data therefor, on a MIC. In the case where the representative frame location data is stored on the tape, a scanning mechanism is provided for scanning the recorded video tape to locate the representative frames. In either form of the invention, multiple representative frames and their location data are placed in a storage mechanism, either temporarily or permanently, and then recorded at a single location, either at the beginning of the video tape or in the MIC. A peripheral storage mechanism may also be provided, in the form of a computer, which may be used to add additional inform…
