but all this cable stuff is kind of out of date. wireless and proximity connections seem to be the future. just got my iphone 4 to start my car and track my kid driving across america. so not sure physical cables are that important in the future.
Wireless still has a long way to go to push 100Mb/s of uniterrupted data. With all these devices on 2.4Ghz spectrum(e.g bluetooth and Wifi) you will see alot of interference when pushing high bit rate data such as HD.
What needinfo117 was illustrating was one of the benefits of HDMI 1.4a which Transwitch is supporting.
Understanding the concept of HDMI 1.4a on the link needindo117, look at the diagram on the middle left. For HDTV that have the HDP technology embedded, you can have one internet connection going to the HDTV (alas 100Mbs hub). Then have your hdmi 1.4a devices (blurway, gaming console, media player, etc) access the internet via your TV without additional ethernetcable.
