Using A Wireless Video Transmitter - Sender 

If you have a TV in one room with a DVD player, satellite receiver, etc and want to watch a program that is playing on that TV in another room you either have to have another satellite box or another DVD player.

There are expensive video distribution systems that you can use. These cost several hundred dollars and you must run wires through the walls and attic.

Here is how I distribute programs to the different TV's in the house.

You can transmit video through walls using a wireless video sender. These are available in 2.4 GHZ and 5.8 GHZ. GHZ stands for gigahertz and is the transmitting frequency. The newer 5.8 GHZ video transmitters have better signal quality and pick up less interference from cordless phones. They do cost a bit more so if you want to save money a 2.4 GHZ will work fine for most applications. 

At the entertainment center where the DVD, TIVO, etc is, I have a X-10 video transmitter. At the TV in the other room I have the X-10 video receiver, which has RCA audio and video out jacks that hook up to the back of the TV.

Our Directv remote is set on the wireless setting instead of infrared. That means it can transmit through walls, so I can control the satellite in the other room. Most Directv remotes are wireless capable.

The X-10 video transmitter is wireless. It uses 2.4 GHZ, like cordless phones. It will cause some interference if a 2.4 GHZ cordless phone is near the unit when you are watching a program.This is not a problem with newer 5.8 GHZ units, although they cost a little more. 

Expect to get a range of about one hundred feet, through walls.

Now, if you have devices that do not have dual video and audio out jacks you may need to go one step further. You can find a video / audio switch on e-Bay to control which devices the video transmitter is sending to the other room.

You hook the three way audio video switch up, using RCA jack splitters available at Radio Shack and all you have to do is turn the switch to determine which one is transmitted through to the next room.

In this case you would have a three wire RCA cable running to each device, one to your Directv, one to your DVD and one to your VCR, etc.

If the DVD only has one video or audio out jack you will need the cheap three way splitter from Radio Shack. This splits the video or audio signal into two paths. You'll have audio going to the X-10 transmitter and on to your entertainment system speakers and video going on to your entertainment center TV and the other side of the video going to the X-10 transmitter.

This is a much better way of transmitting video to another room than cutting holes in your walls and running wires through your attic.

The video quality is very good and the whole system costs less than a hundred bucks.
