The TiVo patent essentially describes continuing to record while viewing data from the past. This has been done for years in computers, files on the disk get written to over time and continuously update while they are read at the same time. TiVo claiming that somehow putting video data in a file and being able to view it at the same time recording is continuing makes it unique shows just how poorly the patent office understands the technology for which they grant patents.
Long before the patent for TiVo was applied for I used a device called a network sniffer, it would record all the traffic on the network, break down the information in real time and allow one to look at the traffic, going back and forth through time and viewing the packets while it continued to record the information coming over the network. It was used to debug things like network file systems and other TCP/IP programs. You could watch the packets go by, pause it, go back and forth and watch the packets again in the past going by. All the functionality of what TiVo claims is unique. Yeah the data being captured at the time was not video, but the whole "time warp" concept was there.
