How do you split digital cable from one TV to Two TVs?

SEVERAL FACTORS. IF YOU ONLY HAVE 1 RECIEVER, PLUG LINE FROM WALL INTO THE INPUT ON YOUR RECIEVER. THEN, HOOK A CABLE WIRE FROM OUTPUT TO A SPLITTER & RUN A CABLE FROM EACH SIDE OF THE SPLITTER TO EACH RESPECTIVE TV. IT IS IMPORTANT TO KNOW THAT BOTH TV'S WILL HAVE TO WATCH THE SAME THING AS THERE IS ONLY ONE RECIEVER FEEDING BOTH TV'S.
