TiVo set-top boxes allow you to record television programs on an internal hard drive. Once recorded, you can watch them at a time of your choosing, pause them or speed through commercials. This kind of functionality has made TiVos a popular replacement for now-obsolete VCRs. Since many modern homes have TVs in more than one room, it can be useful to be able to leave the TiVo in one room and access it remotely. It is even possible to remotely access your TiVo from outside the building using the Internet.
Attach one end of a short coaxial cable (the type with a single pin and screw) to the TiVo's output and the other end into a standard cable splitter available from any electronics store.
Attach longer coaxial cables from the splitter's outputs to the televisions in other rooms. You may need to drill through walls if you don't want to have cables snaking along the floor. If you connect more than two televisions in this way, you will need another splitter and a signal booster, as each time a cable is split, the signal is weakened.
Attach the cables to the coaxial inputs on your other televisions. You will now be able to see and hear the output from your TiVo on those TVs. All televisions attached to the same coaxial line will show the same picture -- you cannot send different programs to different TVs this way.
Connect a remote-control extender kit. Kits such as the Trek LFRIX and NextGen remote control extenders translate the infrared signals of remote controls into radio, and transmit them to the device where the signal is turned back into infrared. This will allow you to use your TiVo remote from any room.
Buy a wireless router that can stream television signals over wireless networks.
Connect the router to your TiVo box using the included A/V cables.
Connect receivers to each television that you wish to have access to the TiVo using the A/V cables that come with the kit.
Turn on the TiVo, the TV and the router. On the TV, select the input that matches the jacks the receiver is plugged into. On the TiVo, select the output that matches the jacks connected to the router. You should now be able to see and hear programming from your TiVo on any TV with a receiver. Once again, this system only allows other TVs to watch one stream from the TiVo. Multiple remote sets will not be able to access different programs.
Connect a remote-control extender to allow you to command your central TiVo from other rooms.
Buy a router that can stream television signals on the Internet.
Connect the router using the included cables to your TiVo. Turn both on.
Look in the router's documentation for the web address to which it sends video.
Connect to that address from any computer. You will now be able to watch content playing from your TiVo at that time. To control the TiVo remotely is more difficult. It is possible to command your TiVo online to make recordings, but full online access can only be done with third-party hacks that are unsupported by TiVo and may void your warranty.
Buy a separate TiVo box for each television in your home. Some discount should be available for such purchases.
Connect all your TiVos to a home network. This can be made up of Ethernet cables running to and from an Ethernet router, or a wireless network with wireless antennas attached to each TiVo. Your TiVos should automatically detect one another.
Connect one TiVo to your television cable and record programs on it.
Transfer recorded programs to the other TiVos using the on-screen controls provided.
Some programs cannot be transferred from TiVo to TiVo, as this may violate their licensing conditions. Those should be indicated by a red circle at the transfer screen.
