My sky hd box is installed downstair in the living room but I would like to watch my sky box hd contents on a second tv upstairs. I have heard of hdmi over cat 5 / 6 but also I have come across android tv box or android media player with hdmi input. The claim is that sky or cable set up box can be connected to android box with hdmi input. If I buy android media tv box with hdmi input, is there a solution or a device that I can run ( maybe over a home network) to an android box to view the hd contents from sky hd box on a secondary tv in another room.
