Abstract

There is disclosed a video frame grabber (260) capable of capturing a plurality of video frames from a played-back video signal during fast forward mode and reverse mode. A closed caption text detector (270) is provided that is capable of detecting closed caption text in the played-back video signal. A memory (280) is provided for storing the detected closed caption text and a plurality of key frames. The key frames comprise selected ones captured by the video frame grabber (260) corresponding to detected closed caption text. A video processor (210) retrieves a line of closed caption text and at least one key frame corresponding to the first line of closed caption text and displays the line of closed caption text with the key frame on the display screen.
