Other wiring involves home theater cables that run from one device to another. HDMI (High Definition Multimedia Interface) cables, similar in appearance to the USB cables that attach devices to a computer, are used to link a signal source to a high definition television set. That device might be a video recorder or digital camera. A HDMI slot is manufactured into both the device and the HDTV for this purpose. Another type of cable is the DVI (Digital Visual Interface); this is the type cable that runs from a computer to a monitor or television; it has twin screws on either side with long, fluted handles to provide an easier grip while being turned. A DVI cable is often used when a computer is integrated into a home theater system.
A coaxial cable is a round wire about 3/8″ in diameter; inside the cable is a single, stiff insulated copper wire which is surrounded by additional foam insulation to enhance signal fidelity. This is a common type cable used often in the past to connect VCRs to a television set; while it may still be used, HDMI cables are becoming more common place as signal load requirements increase.
Linking home theater components to rooms around a house is not particularly hard, though it may be tedious. It can be accomplished with a minimum of intrusion and mess making by using a closet wall as an entry point to the cavities of house’s inner wall system, then employing a fish line to pull the cable through to a wall fitting location. The do it yourself type should practice using a fish line if it is a tool that has not previously been used.
