HDBaseT Technology
The newly finalized cable technology, known as HDBaseT, transfers audio and video signals over ordinary RJ-45 ethernet cables.
The venerable HDMI cable was first produced back in 2003, and the rise of Blu-ray and the growing popularity of HDTV fueled its adoption.
While HDMI has several advantages to other sorts of A/V cables, it isn't without its problems. The technology often suffers from switching delays and is known for its limitations when it comes to cable length, problems that HDBaseT could solve.
HDBaseT will be able to deliver full-HD video, audio, Web connectivity, and power over one cable simultaneously. Whereas a HDMI cable can be no more than a few meters in length, HDBaseT supports cables up to 100 meters long. The new cable spec can also carry 100 watts of power via the cable.
The back of any TV is usually an unsightly mess of cables. If this specification proves popular, it'll mean fewer cables. A single cable would not only power your television, but it could also send in all your data--sound, visuals, and more. Replacing multiple cables with just one is a welcome change.
