Tivo / Echostar Patent Lawsuit Advances

According to this press release, the Tivo patent infringement case against Echostar is slowly moving forward with the court denying motions to move the case out of Texas.

According to the press release, Tivo charges that Echostar infringed on it's "Time Warp" patent:

Key TiVo inventions protected by this patent include a method for recording one program while playing back another; watching a show as it is recording; and a storage format that supports advanced capabilities -- such as pausing live television, fast-forwarding, rewinding, instant replays, and slow motion.

As I mentioned before, I'm a layman when it comes to patents, but the "Time Warp" patent seems pretty broad in scope to me. If the patent gets validated with a few court victories, this seems like a big win for Tivo. It also looks like it's broad enough to stifle other DVR inovation, which isn't so good for DVR enthusiasts.

Patents are always analysed by claims. Claim 1 of Tivo patent says that signal is encoded to MPEG.

I don't know details of Echostar-devices, but if they record directly digital stream from digital network, not ADC what Tivo patent seems to do, they (and everybody else) are on clear waters.
