What is the purpose of an HDMI Extender?
HDMI Extenders simplify the extension of HD video, audio and control signals very long distances. The problem with HDMI cables is their reach limitation, typically 50 feet before experiencing degradation. Applications such as a restaurant, large facilities, schools or meeting rooms usually require more than 50 feet of distance to send an HD signal.
There are many different types of applications, hence many types of HDMI extenders. The most current of extenders are HDMI Extenders over Cat5, which send HDMI signals via UTP/category cables. Other types of HDMI extenders use fiber cables, coaxial cables or even wireless. HDMI extenders over Cat5 are also known as HDBaseT Extenders. HDBaseT extenders have gained notoriety over the years for its capability to extend an HDMI signal up to 330 feet (100 meters). HDBaseT allows transmission of audio, video, control, power and Ethernet, making it an excellent solution for integrators, installers and end users. If you don't need to extend that far, for shorter distances, a coaxial extender for HDMI will reach about 100 feet. Coaxial HDMI extenders are suited for residences with pre-wired coaxial cables. In a scenario where you need to extend over 1000 feet, then a fiber optic extender is required.
Manufacturers have been exhibiting a variety of HDMI extenders to suit the needs of critical applications. These extenders may be as common as HDMI only or distinct as HDMI with bi-directional IR and RS-232 for simple control of each zone. Another addition that supplements IR and RS-232 is Ethernet. These models of HDMI extenders are utilizing HDBaseT technology allowing the user to send HDMI signals with control, audio, and power.
HDMI extenders have taken new shape with features such as IR, RS-232, and Ethernet. The typical HDMI extender was just a plain black box with an HDMI input and output, but some extenders are now wall plates that can be mounted on walls. Other types of HDMI extenders have transmitters with multiple outputs for splitting a signal while receivers may at times include loop outs to assist with daisy chaining a signal. Industry leaders including Avenview, Kramer, Gefen, Shinybow, Atlona TVOne, Hall Research and more have added these extenders to their catalog.
