I would like to be able to send two HDMI signals from my living room to my bedroom and be able to switch between the two sources from the bedroom. Basically I have Sky in the living room and have an HDMI output from my home CCTV setup. I currently just have the CCTV running through an HDMI splitter to the living room and the bedroom so I can view the CCTV in either room. I would now also like to run the Sky output to the bedroom but be able to switch between the CCTV and Sky. Ideally I would like to use the existing CCTV HDMI lead that runs from downstairs to upstairs (10m cable). But maybe the best route would be an HDMI extender over ethernet. Any advice would be welcome.
