Abstract

The invention concerns a method (200) and system (100) for identifying a work to be stored on a storage medium. The invention includes the steps of: automatically selecting (212) at least one picture from the work; and verifying (214) that the selected picture contains a sufficient amount of information to be an identifier for the work. The invention can also include the steps of repeating (216) the automatically selecting and verifying steps until a suitable selected picture can be verified. The invention can also include the step of processing (218) the selected picture to create identifying data for the work. In one arrangement, the work can be an MPEG video segment containing at least one group of pictures (GOP) and the selected picture can be an intra picture from the GOP.

Description

technical field [0001] The present invention relates to a video recording system, and more particularly, the present invention relates to a video recording system for recording digitally encoded video sequences onto disk media such as recordable digital video disks, hard drives and magneto-optical disks. Background technique [0002] Many storage media containing recorded data include one or more menus that can be used to enable a user to locate a particular portion of data on the storage medium. These menus can list the title of each work stored on the disc together with a set of commands enabling the user to perform an operation such as accessing the work identified by the title. Additionally, the title of each listing may contain a corresponding image representing the work identified by the title. For example, if the work is a video recording of a particular program, then images from the program may be positioned close to the title identifying the recording. This image ...
