Whats So Special About HDMI Cables?
Before we jump into the tests and results, An HDMI cable is actually a bundle of wires – 19 counting the drain wires, and all follow a very rigorous specification in order to deliver the extremely high bitrates that deliver high definition images and audio to your electronics. Here is an example of how one particular geometry of HDMI cable would look if you sliced it open: Looking at the image above you will see that there are 4 primary paired connections which represent the TDMS (Transition Minimized Differential Signaling) channels plus a drain wire. This can be thought of as the red, green, and blue color information (note that the colors are presented solely for illustrative purposes), multi-channel audio information and also the clock. The multi-channel audio is “easy” to pass along the line and is therefore interspersed among the much denser video information carried across these cables. Because of this, there are no dedicated wires for audio. While the three color/audio TDMS cha
