house was built with one cat 5e and 2 RG6 home runs to each room
all video sources are in the main viewing room (also near a cat 5e drop)
all sources are run through a ChannelPlus SWM-22 modulator, and the output is sent over RG6 back to the wiring closet and then out to the other rooms
there is a separate IR repeater network
all sources and TV's are SD
I am trying to estimate the minimum cost of modernizing. I would like to keep all sources in one room, and just distribute one 1080p "channel" to the other rooms. I also want to reserve the cat5e cable for use by our gigabit Ethernet. I would also like to avoid anything wireless.
Can this be implemented with decent quality for under $1000? (I imagine this budget precludes running new wires).
I think I've included all the necessary info, but if I've missed anything, please ask.
Thanks in advance for your time and advice.
