I am a newbie with a new Panasonic plasma HDTV, and have not yet requested a set top hdtv cable box from Comcast. For the time being I am considering using over the air hdtv via an antenna for my hdtv programs and Comcast cable for standard broadcast programming.
Is there something out there similar to the old A/B switches that one used years ago to change signal sources. Moving the tv stand to access the rear of the tv is a major undertaking.
Any insights or suggestions would be appreciated.
