Specifically my requirements are to have:
Audio and Video in 11 rooms, and audio only in a further 3 rooms which are linked with the same output as three of the original 11 (so just sub zones), ideally with the sources all being in a central hub (a rack in a cupboard). I want each media point to have independent control of what they watch or listen to, so in fact to be able to do 11 different things at the same time and control what they are doing with a remote, at the media point.
As an idea of budget, excluding the cabling, projector, speakers and televisions, sky boxes and ariels (so mainly focusing on switches, remote controllers, IR extenders, servers, clients, drives, streamers, amps if needed) I am trying to come in somewhere between £2000 and £3000, the more complete a system, the more integrated and centrally controlled, the more functionality, the more I would spend I guess... Of course, if my expectations are entirely unrealistic, then I need to be told that and told what budget I should be looking at... I do however prefer to compromise on my requirements where possible, to keep within budget
