HDMI Do-it-yourself
     
  At this moment there is no such thing as "Do-it-yourself HDMI". There is no tooling, connectors, or HDMI bulk cable on the market. The good news, there are alternatives. You can purchase HDMI wall plates that your HDMI cable plugs right into. Cables are available with no loss up to 82 feet. The problem is that the price is quite high, but the performance is the same as a 3 foot cable.
   

 

 

 

 

 

   There are a couple of alternatives,  one is the Rapidrun system. RapidRun Digital is centered on the Runner cable. Installations are easier than with traditional HDMI or DVI cables because the RapidRun Digital Runner fits through ¾-inch conduit, even with a 90-degree sweep! Termination is fast and simple; just attach the appropriate Break-Away Wall Plate or Flying Lead to the Runner. Add a choice of passive or active wall-plates to ensure performance with a wide range of products and installations.

RapidRun Digital crushes standard HDMI and DVI length limitations with dependable performance to more than 65 feet, even at 1080p resolution! The RapidRun Digital Active Wall Plate is the first HDMI/DVI wall plate solution with an integrated equalizer/extender. The extender corrects for attenuation and impedance so that the signal can be transmitted over a runner cable as long as 65 feet. A Flying Lead or passive RapidRun Digital Wall Plate with a standard HDMI or DVI interconnect terminates the runner cable.
 
   
 

Another alternative is made by Wireworld who has introduced a new line of HDMI extender systems that are designed to transmit HDMI (high definition multimedia interface) signals up to 300 feet over a pair of low-cost, small-diameter, and readily-available CAT 5e or CAT 6 cables. These systems are an ideal solution for transmitting HDMI over structured cabling, and allow for routing of systems through conduits or in-wall installations where standard HDMI cables would difficult or impossible to install.

Each Wireworld HDMI extender system includes a transmitter, receiver, and a power supply which connects to the receiving end of the system. They are designed to work with standard unshielded CAT 5e and CAT 6 cable for compatibility with nearly every structured wiring system in use today. The systems fully HDCP compliant, and support all major high definition video formats, including 480i, 480p, 720p, 1080i, and 1080p standards. The systems are capable of clear, distortion-free transmission at lengths of up to 150 feet for the most common 1080i and 720p standards, and over 50 feet for 1080p, the highest home theater resolution standard in use today. When used with conventional 480i broadcast video or DVD signals, the extenders are capable of transmission lengths as high as 300 feet.
