Wat is the joke??
Because third party products don´t solve this ??
If you have a beovision 7 with build in blueray and settopbox you can link this to link room thru antenna system as always, but only in SD quality of cource (tuner in link tv and modulator in antenna system are analog device)
the reason why blueray player don´t send both HDMI and composite it´s legal reason (Don´t ask me why) but that is the fact!
you can use for example Atlon AT-HD530 HDMI - composite downscaler for ATV MacMini and other sources with HDMI but without HDCP
protection to get picture and sound in linkroom
And if you want HD quality in linkroom you have 2 possibilities:
1. install separate blueray and settop boxes on each linkroom tv
2. install Beonet cabling (CAT7x2) to each link room from atlona Matrix 4x4/8x8 depend on how many sources and linkroom
