Connections & Setup18 Chapter 1ETHERNETExplanation of Input Jacks and CablesThis section describes the jacks and cables you might use to make connections (cables may be ordered separately by usingthe order form on page 85). There are several ways to connect components to your TV.Different jacks and cables provide a different level of performance. It’s important to remember the different degrees ofpicture improvement for comparison. The component jacks are considered an excellent improvement; S-Video andcomposite jacks are considered very good, while connecting components with the antenna RF connection is good.DVI-HDTV (Digital Visual Interface-High Definition Television) ConnectorDVI-HDTV is an uncompressed, high-speed digital visual interface designed todeliver digital video in its native format. It supports the overlay of high-resolution graphics used by some program guides and interactive components.Note: Remember to connect the left and right audio cables for Input 5(DVI-HDTV) because the DVI-HDTV cable carries only the picturesignal, not the sound.DTVLink® (Digital Television Link) ConnectorsDTVLink uses a format better known to some as IEEE-1394 or FireWire®.DTVLink is a compressed digital video input/output offering an IEEE 1394-typeconnection that meets the CEA specifications. This connection is a high-speedand inexpensive way of interconnecting 1394 compliant consumer electroniccomponents. If your 1394 component has the DTVLink logo on it, it shouldwork with this TV. You can use either or both connectors to link yourcomponents but don’t connect the components in a loop.Notes: Audio and video information is carried on a single wire.The TV outputs audio/video through the 1394 jack (labeled DTVLink)only to a component that enforces video copy protection.Digital Audio Out Jack and Optical CableThe optical cable is used to connect an audio receiver with Dolby Digital orPCM (Pulse-Code Modulation) audio receiver to your TV. If you own a receiverthat uses an optical cable input, you can use an optical cable to connect the TVto that receiver for the best sound quality.Note: This TV’s optical digital output jack fully complies with theinternational standard governing this type of jack (IEC958), and isdesigned for connection to a Dolby Digital (AC-3® or PCM) receiver orDolby Digital (AC-3 or PCM) decoder. Older equipment, some of which isnot fully compliant with IEC958, may not be compatible with the DolbyDigital bitstream. Such a connection using anything other than a DolbyDigital (AC-3 or PCM) receiver or decoder could create a high noiselevel, causing damage to headphones or speakers.Ethernet Jack and CableThis jack is used to connect a router, cable modem or DSL (Digital SubscriberLine) unit with a CAT 5 (ethernet) cable (not provided). It is recommended thatyou only connect a router to this jack although you could connect a DSL/cablemodem directly.Digital AudioOutput JackVIDEOINPUT 5DVI-HDTVDTVLink® Certification Logo is a U.S. registered mark of CEA.FireWire® is a trademark of Apple Computer, Inc., registered in the U.S. and other countries.
