SonicBlue has been granted a multi-claim patent that covers almost every aspect of digitally recording TV programmes on a hard drive, in particular using a channel guide to manage what the machine records.
The patent, number 6,324,338, was filed by ReplayTV back in the summer of 1998. Since then ReplayTV was bought by SonicBlue - the deal was signed last March and completed in August. SonicBlue is now claiming the intellectual property for its own.
The patent describes a "video data recordable having integrated channel guides allowing a user to control recording and storage of television signals into personal channels for later playback and viewing". It covers pretty much anything you can do with a digital video recorder (DVR), including filing recorded programming into channels, providing previews, storing recordings on a random-access system, and making selections according to programme type and information culled from viewing habits. In short, the works.
