It appears that the only route for surround music coming into the home is television. HD Radio is fading and FM stereo will not do Dolby ProLogic 2 matrix encoding.due to multipath and downmixing issues. However ATSC-DTV is set up fro 5.1 music surround. Many home have 5.1 setups with their HDTVs. Perhaps we can have a surround music radio station using a subchannel of a DTV station. It would take less bandwdth than a SD TV subchannel. perhaps, GBH could try it, or ZLX could be on a subchannel of WBz oe WSBK,since ZLX is doing 5.1 (prototype) on their HD-1 signal.
