As an alternative to using cables, you can also use Wi-Fi to connect computers and TVs wirelessly. Because televisions do not ordinarily support Wi-Fi, you will need to install a separate unit between the computer and TV. One common solution is called a Wireless PC to TV system or [i[Digital Media Receiver. These products connect via AV cable to the TV and supply Wi-Fi connections to any computer in the home.
Another wireless PC to TV connectivity option is based on Windows Media Center Edition (MCE). If you purchase a Windows XP or Windows Vista PC with the MCE application included, this system contains built in wireless connectivity support for streaming images to your television. Some of these systems also support TV tuner cards that allow your computer to receive incoming television signals. Finally, you can extend the capability of a Media Center PC across an entire wireless home network by installing a Media Center Extender product like the LInksys DMA2100.
