|HDMI (High Definition Multimedia Interface)||
|A digital connection that combines video and audio into a single interface. HDMI supports video in 480i, 480p, 720p and 1080i. The HDTV and Spectrum receiver connected by HDMI cables must synchronize before displaying video. The HDTV must support HDCP, otherwise the screen will be blank, without audio.|
|An analog interface that uses a 3-wire connection for 3 components of the video (Red, Green and Blue). It's also called YPbPr. Component supports displaying video in 480i, 480p, 720p and 1080i. An audio connection can be completed by using the Composite audio connections or SPDIF connections (see below).|
|An analog interface that uses a 3-wire connection: 1 video (Yellow) and 2 audio (White, Red) with RCA connectors and jacks. Composite only supports video in 480i.|
|RF (Radio Frequency)||
|A standard input used to connect digital television antenna to a TV using a coaxial cable. With this type of connection, the audio and video are modulated onto analog channel 3 or 4. RF only supports video in 480i.|
|An analog interface that uses a 4-pin connection for video only. It is also called Y/C. An audio connection can be completed by using the Composite audio connections. S-Video only supports video in 480i. An S-Video connection will provide better video quality than an RF connection.|
|DVI-D (Digital Visual Interface-Digital)||
|A digital interface that sends out a digital signal only. DVI-D supports video in 480i , 480p, 720p and 1080i. An audio connection can be completed by using the Composite or SPDIF connections. The HDTV and Spectrum receiver connected by DVI must synchronize before displaying video. The HDTV must support HDCP, otherwise the screen will be blank, without audio.|
|HDCP (High-bandwidth Digital Content Protection)||
|A specification applied to DVI and HDMI connections to provide content protection over the digital connection. All Spectrum receivers use HDCP on their digital connections. TVs must also support HDCP to be connected to the receiver by DVI or HDMI. No audio or video will be available through the DVI/HDMI connection if the TV doesn't support HDCP.|
|A digital audio connection using either a coaxial connection with RCA connectors or an optical connection using multi-mode fiber. SPDIF supports stereo and surround sound audio.|
|Uses a 4-pin or 6-pin connector. 1394 supports video in 480i, 480p, 720p and 1080i. It also carries audio. The Interactive Program Guide overlay graphics aren't supported in the 1394 specifications for video streaming. Therefore, 1394 isn't recommended for use as a primary display interface. It can be used in archiving content to 1394 Digital VCRs. This video connection generally can't be used to connect to PCs, media devices, etc.|
