High Definition Over Cat5-Cat6
The ability to send High Definition and 3D pictures with full Dolby Digital surround sound to multiple televisions in your home or business. Runs of up to 50 meters can be achieved by sending the HDMI signal over a run of Cat 5/6 networking cable, using adaptors designed for this purpose. They incorporate booster and equalization electronics at each end of the path.
HDMI over coax
This technique consists of a transmitter / receiver pair that convert HDMI signals for transmission over coaxial cables. The benefits of this solution are long reach (up to 300 feet at 1080p resolutions), the ability to easily terminate connections in the field, and an easy upgrade path for existing coaxial installations in office or commercial installations.
HDMI over Fibre
The longest HDMI cable runs seen to date have been achieved using fibre optic cable, which is far less susceptible to attenuation and interference than copper. Electrically it is similar to an active cable or Cat 5/6 solution, the principal difference being the higher-quality optical cabling between the transmit and receive connectors. HDMI over fibre is a highly robust solution, effective in cable runs up to 100 meters or more with minimal data loss.
