How to Convert a Cable TV Input to HDMI

HDMI stands for High-Definition Multimedia Interface. The clear and crisp HDMI picture is the result of digital video and audio, and it is made simple by using a single cable to connect the digital video and audio signal to your HDTV. Converting cable TV input to HDMI requires an HDTV cable converter box that has an HDMI port. This box can be obtained from your cable service provider, and when you request your box you should ask if the company provides the HDMI connection cable as well.
