1. A personal video recorder comprising:
- an input for receiving an audiovisual signal and an output for outputting said audiovisual signal;
a buffer for buffering said audiovisual signal, said buffer retaining a portion of said audiovisual signal after that portion has been output by said recorder;
a data storage unit; and
a processor that receives input from a user input device;
wherein, upon receipt of a user command input through said user input device, said processor automatically records a segment of said audiovisual signal in said data storage unit, said segment of said audiovisual signal comprising;
a first predetermined amount of said portion of said audiovisual signal retained in said buffer; and
a second predetermined amount of said portion of said audiovisual signal output by said recorder after receipt of said user command;
wherein said user input device receives parameters from a user that specify said first and second predetermined amounts, said processor then receives said parameters and automatically records said segment based on said parameters.

Abstract
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.
