High definition signals cannot be delivered by coaxial cable they can be delivered by HDMI(high definition multimedia interface) or 3 component cables plus either 2 audio cables or TOS Link optical cable. Due to the cost of these cables and cost of putting them in the walls after construction additional receivers would probably be the better choice.RAkin said:I currently have an HR10-250. One HDTV is located at the receiver and connected there. Two SDTVs are connected via coaxial cable in the walls and are a good distance away in other rooms. If I were to replace one of the SDTVs with an HDTV, how would I connect to this receiver? Would I need to upgrade to the HR20? Is there a wireless solution? Is the coaxial cable useless for an HDTV connection?
Any suggestions would be appreciated.
