Problems solved by technology

Therefore, when the computer hard disk is full, prior art disk-based video recorders either stop recording, or overwrite existing programs with some limitations.
Unfortunately, the way prior art disc-based recorders rewrite existing programming is rather crude

Abstract

There is disclosed a video memory manager for use in a video recording device that stores of video programs on a disk drive. The video memory manager comprises a video memory controller for detecting that the disk drive does not contain sufficient storage space to store a next-to-be-recorded program. The video memory controller, in response to the detection, determines a first retention score associated with a first video program and a second retention score associated with a second video program. The first and second retention scores indicate a desirability of retaining the first and second video programs respectively. The video memory controller deletes a least desirable one of the first and second video programs.

Description

[0001] technical field of invention [0002] The present invention is directed generally to video recorder devices and, more particularly, to a memory management system for managing the storage space of a disk drive based video recorder. background of the invention [0003] VCRs are among the most popular consumer electronic devices on the market. The most common type of video recorder is the video cassette recorder (VCR), which records several hours of television in analog format on a cassette tape. A VCR can record television programs received by a local antenna or cable system for later playback. Most VCRs can be programmed to record television from a user-selected channel, beginning at a user-selected start time, and ending at a user-selected end time. [0004] Recently, however, VCRs have come on the market that store television programs using a computer's hard disk rather than cassette tapes. For example, Replay TV TM Logger and TiVO TM The recorder digitally record...
