Sounds like a DMA memory controller
Crap, I hate these patents. Anyone here ever herd of a DMA hard drive controller (vs PIO mode which hasn't been used for 20 years)?
TiVo really didn't invent this.
"hardware device" - I don't think this is the patent currently being reviewed. Wasn't it a software patent have to do with indexing into mpeg files to provide for smooth trick-play operation?
(Don't want to get sucked into a war - I'm going to shut-up now).
Tivo Media Switch is a 3 port bi-directional hardware device used to pass input source stream directly to HDD and from HDD to output bypassing the CPU and enabling a DVR to use a slow cheap CPU's cutting the cost to build a DVR by more then 50% savings.
