How to Convert CATV to HDMI

CATV (cable TV) is a connection protocol that transmits video and audio signals over a coaxial cable, which is the standard connection for cable TV service. A CATV line enters a building where it typically connects to a set top cable box. In some cases, such as connecting two TVs to the same cable box, you might want to run a CATV directly to a high-definition TV equipped with an HDMI (high definition media interface) jack. Powered converters available at electronics stores connect the CATV cable on one end with the HDMI cable on the other.
