Are you looking to connect two different HDMI devices across distances greater than 30ft? Wel, in that case you must use a HDMI extender or more commonly called Repeater. A HDMI extender is a device that can be used to connect two HDMI enabled devices at distances greater than 30 ft. This is particularly so because generally the quality of signal starts to degrade at distances greater than 30 ft.
A HDMI extender or a repeater basically is a device which receives a signal, and then amplifies it and then passes on the signal to the output port. This helps in transporting a signal across great lengths (distances in signal terms, not to be taken literally :) ) without any degradation in the quality of the signal. Thus, as the quality of the data transferred due to signal attenuation and sine wave disturbances, the necessity for a signal booster like a HDMI extender increases greatly.
HDMI extenders have greatly reduced the cost in multi floor/level buildings where the same signal has to be transmitted across different devices located at different floors. HDMI extenders are ideal for your office, homes and all other such places where you may be using HDMI enabled devices spread across different rooms or at distances greater than 30 ft.
HDMI extender is just like a box and can be easily camouflaged with the surroundings because it generally goes unnoticed due its small size. These days you can find HDMI extenders which can connect devices upto distances of 250ft effectively without any degradation of the signal to result in the best quality picture and sound.
There are various vendors selling HDMI extenders with different range capacities. Range capacity means the distances up to which signal from the HDMI extender can be sent effectively. Certain extenders are compatible with both HDMI and DVI cables but also cost much more than those only supporting HDMI ports.
Some of the vendors selling HDMI extenders are listed below
* www.avextender.com - extends over CAT5 cable up to 300 ft.
* www.octavainc.com - extends both HDMI as well as DVI upto a distance of 150 ft.
* www.engadgethd.com
* www.gefen.com - Gefen is the same company which came out with concept of wireless switchers and splitters. It seems like they have decided to go all against wires and cables, and have decided to make all the devices wireless. Anyways, although a bit on the expensive side, it still is the latest kid on the block and brings in style as well as comfort to your home and office. Gefen wireless extender is truly a world class product.
