The TiVo Digital Video Recorder
TiVo DVR serves a function similar to a videocassette recorder, in that both allow a television viewer to record programming for viewing at a later time. Unlike a VCR, which uses removable magnetic tape cartridges, a TiVo DVR stores television programs onto non-removable hard disk storage. Also, the TiVo device does not have any buttons on the front panel; its functions are solely controlled by remote control.
What distinguishes TiVo from other DVRs is the sophisticated software written by TiVo Inc. that automatically records programs — not only those the user specifically requests, but also other material the user is likely to be interested in. TiVo DVRs also implement a patented feature TiVo calls "trick play," which allows the viewer to pause live television, and rewind and replay up to a half hour of recently viewed television. More recent TiVo DVRs can be connected to a computer local area network, which allows the TiVo device to download information and even video programs, music and movies from the Internet.
TiVo polls its network, receiving program information including description, regular and guest actors, directors, genres, whether programs are new or repeats, and whether broadcast is in HD. Information is updated daily from Tribune Media Services.
Users can select individual programs to record or a "Season Pass" to record an entire season (or more). There are options to record First Run Only, First Run & Repeats, or All Episodes. An episode is considered "First Run" if aired in two weeks of the original air date.
When user requests for multiple programs are conflicting, the lower priority program in the Season Pass Manager is either not recorded or clipped where times overlap. The lower priority program will be recorded if it is aired later. TiVo DVRs with two tuners record the top two priority programs.
Hope this helps
