Hi, I need help!

I'm trying to connect my sky and dvd player to multiple tv's in my backpackers hostel & bar using RCA cables but it's a bit more complicated than I thought! Here's the setup I want, hopefully I'm being clear enough;

The sky and DVD player need to be connected to a single TV in the guests TV lounge.

They also need to be connected to my amp and speakers in the bar in the adjoining room, and then the video signal distributed via a splitter to 3 TV's in that area.

I'd like to be able to switch between Sky/DVD in the bar and the tv room seperately.

Hope that makes sense!!

Best thing to get in that case is an AV matrix switch, connect the 2 inputs to it and then the 4 outputs around to the displays. That will let each display be set to one of the 2 inputs independantly.

You cant just split RCA video signals like RF, it needs to be an active device. There are some made for car use that are pretty cheap rather then looking at the home automation stuff.

Otherwise connect the outputs of the dvd and sky direct to one display, and then take the composite from both to an input selector switch, and then take that to a video distributor.

Something like 220482445927 on ebay - there are heaps out of hongkong - just add a 12v adapter and it will do what you need as far as driving several displays off a single source. You may still end up with groundloops etc tho, that will effect anything thats driving multiple displays on different power circtuits.

Anything that doesnt take power is not an active splitter. Sure, you can try some RCA Y cables and see how they go first, but chances are it will be blury, dim and possibly loose vertical sync often because of the low signal levels and poor impedance matching.
