A personal video recorder (PVR) includes a "bookmark" feature with which a user can specify and capture segments of an audiovisual program, for example, a television broadcast, that contain information or content that the user wishes to record for later access. A dedicated button on the PVR or a remote control sends a "bookmark" command to the PVR which causes it to record a predetermined number of proceeding and following seconds of the program content. The preceding video signal is taken from a buffer in the PVR, with succeeding video being recorded as it is passed through the PVR to a connected television set. Each captured clip is indexed and labeled for subsequent retrieval.
