HDTV cable box
A Microsoft Xbox console connects to audio/video equipment in one of two ways, depending on the age of the gaming system. Older Xbox consoles use component cables to connect with other AV devices, such as an HDTV cable box, and a proprietary plug system for connecting to the Xbox. Newer models take advantage of higher-resolution digital technology with High Definition Media Interface (HDMI) cables. Hooking up either type of connection takes only a few minutes.
Check the back of the Xbox to see whether it is equipped with a six-sided HDMI plug containing 19 holes arranged in three rows. If there is an HDMI jack, continue to Step 2. If not, skip to Step 3.
Insert an HDMI plug into the port on the back of the Xbox with the wider end of the plug turned upward, then connect the other end to an HDMI IN port on the HDTV cable box.
Connect the proprietary plug to the Xbox port with component cables on the other end.
Attach the RGB (Red, Green and Blue) component video plugs on the Xbox cable to the color-coded Video IN jacks on the HDTV cable box.
Attach the white and red audio plugs from the Xbox to the Audio IN jacks on the HDTV cable box, using the white plug for the left channel and the red plug for the right.
Use the HDTV cable box remote control to select the component input for the television, either cable programming or the attached Xbox for gaming.
Unplug all equipment from the power while connecting AV cables.
