Have the cable run to a closet and to your living room where you would put your TV, from the closet put a server rack and install a network switch and a patch panel, for home use you dont need that many ports so you can get away with a cheap switch. And then you can run ethernet to your rooms, and a few wireless access points. This will also set you up to put say a media server in that closet so you can access movies from anywhere in the house, or use a server set up there for backups. Down the line.
