I am not sure of proper protacol here but here goes. I need to add Blu ray player to existing sytems and would like to use HDMI for optimum signal (assumption on my part) but only have two HDMI connections on the TV. I want to be able, of course, to use home theater system with the blu ray. Will this scenario require a splitter of a HUB? I am not well versed in modern techno language so please keep it simple for a guy who is just over the rise (not quite over the hill??!!
