The main advantages of using this kind of devices are convenience, flexibility and cost savings. It is convenient because you don't have to run long wires around the house to connect between the video source and the video display. It is flexible because the wireless receiver can be moved around easily, with no need to install new wires or re-route old ones. It saves money because you don't have to buy extra devices such as a second cable box or a second DVD player in order to watch video in a second room.
It is not just the cable TV box to which the transmitter can be connected. Other video sources like DVD players, DVR or TiVo boxes, satellite boxes etc can also be connected. This way you can watch not only live TV programs, but also DVD films or pre-recorded TV programs on your second TV. It can also be used to do audio transmissions. The wireless video transmitters generally accept RCA cables as inputs. So provided that the particular audio source has RCA outputs, it will be able to connect to the transmitter. Let us say you have a PC with a sound card having RCA outputs and you connect it to a transmitter. If you then connect a set of speakers to the receiver located somewhere else, you can listen to the MP3 songs stored on the PC without having to sit next to it.
The frequency of transmission is also an important consideration when purchasing a wireless video transmitter. Many of these devices operate in the 2.4 GHz band. The problem is that it greatly increases the likelihood of interference with other appliances. Microwave ovens, Wi-Fi networks and many cordless phones operate in and around the neighborhood of 2.4 GHz. It is quite common to switch and use one of these devices will interfere with the operation of others. Many devices have the ability to select channels to use, and this can reduce the problem of interference shortly.
The good news is that there are transmitters that operate at 5.8 GHz, 2.4 GHz congested. These units of 5.8 GHz, and are therefore less likely to suffer from problems of interference, because most household electronic equipment do not operate around 5.8 GHz. Recently, manufacturers have begun to introduce new 5.8 GHz cordless phones, so you must be careful that in order to avoid potential conflicts.
This electronic gadget, you can watch TV or listen to music anywhere in your home. It only takes a few minutes to create without complex installations and expensive accessories.
