cables are connected as follows:
• The green port labeled Y connects to the cable carrying the Y signal.
• The blue port labeled Pb connects to the cable carrying the Pb signal.
• The red port labeled Pr connects to the cable carrying the Pr signal.
• The red port labeled R connects to the right audio channel.
• The white port labeled L connects to the left audio channel.
These connectors support 480i, 480p, 720p, and 1080i analog standard and high-definition format inputs. The TV
