I'm about to have a large kitchen extension built, which will turn my kitchen into a kitchen/dining/sitting area. Currently I have a 26" TV and a Sonos Play:5 system in the kitchen. The TV can be used to watch Sky and digital, but through a coaxial cable, so not in HD. I have a Sky HD box, 50" plasma and surround sound system in the lounge. As part of the extension I want to include the following: - Large HD TV - at least 40", possibly larger. This would be positioned in the sitting area and will have a PS3/PS4 hooked up to it, so will be used for watching HD TV, playing games and watching blu ray DVD's. - 2nd smaller TV (possibly the existing 26" TV) in the kitchen area. - New speakers (ceiling?) - Sonos system What I would like to achieve is the following: - To be able to use the speakers for listening to music via the Sonos system AND for surround sound when using the large TV/PS3/PS4 - To get Sky HD on the big TV (in HD, not via a coaxial cable). The options here are to subscribe to Sky multi-room or to somehow connect the TV to the Sky HD box in the lounge to enable a HD signal. I would appreciate any comments on the setup and any advise on how to achieve this. Thanks.
