Although there are many ways to send a video signal
First, it is very easy to use composite video because it is a very clearly understood and implemented standard. Additionally, because it has been in existence for so long it is one of the most universally accepted types of video interfaces and can still be found on most modern televisions. One of the things that you will want to consider when looking for a Composite Splitter is to make sure that it not only splits the signal but that it also amplifies it. If it were to simply split the signal without amplifying it, the Composite Video Splitter could end up degrading the quality of the signal by the time it reached the monitors. Amplified Composite Splitters use an independent power supply to boost the signal for transmission. In addition, there may be times when you need to use a composite cable over long distances of up to 1000 feet. If this is the case, there are some composite video distribution amplifier units that are available which can be used along with Cat5/Cat6 cable to achieve that purpose.
Video splitters have made a great impact in the technology how videos are transmitted to different destination devices placed at a farther distance from the source without actually increasing the cost to the owner and also without degrading the video quality or hampering the video resolution, prior to the existence of these intelligent video splitting and amplifying devices, its even hard to imagine what used to happen to the quality of the video signals that were received at the destination device. Well I hope that's the best part of our times, as we have seen the evolution of the best types of technical advancements.
