If you want to watch video on a second TV in a different room away from where your audio-visual equipment’s are normally located, you may want to consider getting a transmitter. It is a two-component system consisting of a wireless Wireless Video transmitter and a wireless receiver. To make it work, first connect the transmitter to a video source such as a cable TV box and the receiver to the second TV in, for example, the garage. When switched on, the transmitter sends continuous TV signals across the air to the receiver. The receiver in turn feeds live TV pictures to the second TV in the garage.
