The Cisco Explorer 4640 HDC is a high-definition set-top box available through Time Warner Cable TV service. The box is designed specifically for high-definition TV (HDTV) sets. A Coaxial cable connects the Time Warner service to the set-top box. The box then connects to an HDTV using either component (red, green and blue plugs) or high definition media interface (HDMI) cables.
