HDTV is available today in all shapes and sizes. If not the HDTV screen then the project, but in all the cases the general trend is to move from standard definition to high definition. With increasing popularity come issues with cable length and picture quality. HDMI extender is ideal for such situations.
HD experience has a lot to do with the bandwidth and the strength of the signal. Since HD pictures are larger than standard definition ones, they need higher bandwidth. Now with CAT 5, CAT 5e, CAT 6 and fiber cables the bandwidth issue has been well tackled by the industry.
The next challenge is the signal strength. Typically for short distances the standard HDMI cable works well. However now the HDTV is entering conference rooms, public displays and other places. The typical characteristics of these areas is that the display screen can be pretty far from the actual video source.
The increased distance means that the signal attenuates more before reaching the HD screen. When this happens you really do not get the true HD display. The best solution for this is to use the Extender. This is more like a signal booster that can bring back the signal levels to the source level and this way the screen gets a better signal to display.
The HDMI extenders as the name suggests need to support various media on which HD signals are transmitted today. Hence most common extenders would support CAT5, CAT5e and CAT6 cables for indoor and domestic usage. The more professional ones also support single mode and multi-mode fibre ports too.
While these can be used for HD signals they will also support SD signals too and both these are transmitted over the same media. The only difference while you are planning the network layout is to look at the picture resolution. The 480p pictures can be extended much longer than the 1080p pictures. So the extender usage really depends on what kind of signal are you transmitting.
In short, HDMI extender can really make your life easy and help you display HD picture and videos on any screen at any distance from the source. This is what really makes this unit a great buy for commercial broadcast displays. Depending on where you want to place this extender you need to trade-off between the size and durability of the box with its price. But whatever you choose you are assured of great pictures and videos all the time.
