I'm looking to equip my boat with the ability to stream video, music and music videos to multiple TVs around the vessel.

Please could you help me with the best options to achieve this. I have read a little about AV extenders but can only really find a single sender to receiver which would work with a single display, but I want the ability to send a media signal from a PC to four TVs in various locations around the boat.

What would be the best way to do this, is there a wireless option? Or does it have to be cable?

Any help or guidance would be greatly appreciated.
