Video & Audio Cables

Guiding you through the jungle of cables.

The two tables below are broken down by Video and then Audio cables. Each list is sorted by the quality of the connection, with the best quality being provided by the last cable in each list.

Video Cables

Name
Cable End
Connector
Technology Description
Coaxial

- Coaxial cable carries video and audio.

- This type of connection screws on. 

Composite

- Composite video cable is made with a coaxial cable but with a push-on RCA cable end.

- This cable carries video only - no sound

- The quality of video compared to coaxial is the same.

S-Video

(Separate Video)

- S-Video provides a brighter and sharper image than the previous types of video cables.

- Make sure the pins are aligned before pushing it in.

- S-Video carries only video signal.

Component*

- Component video cables are the first of HDTV compatible video cables.

- This cable is often mistakenly referred to as RGB (Red/Green/Blue) cable.

- Component cable is made up of three coaxial cables with push-on RCA cable ends, the colors must match up in order for the cable to work properly.

- Component cable carries video only - no sound

DVI*

(Digital Video Interface)

- This cable was a very popular choice for earlier high-end HDTV's.

- In order to use a DVI cable, the television must be HDCP compliant. HDCP (High-bandwidth Digital Content Protection) protects the digital video signal from theft. If a television is not HDCP compliant, the picture will not show up on the screen.

- DVI carries video signal only.

- The DVI cable connects by aligning the pins then pushing the cable into the connector, followed by tightening the thumb screws on the sides of the cable end.

- The Eastlink Installer will determine if you require a HDMI-DVID cable

- The Installers will place a Special Item Order to request cable for you, and the cable will be shipped to you

-These cables are not provided by Eastlink if you upgrade your TV after the initial installation.
- This cable is used when you require a high-definition video connection and your digital receiver has an HDMI output but and your TV only has a DVI input.
- This cable does not carry audio like an HDMI cable will.

HDMI*

(High-Definition Multimedia Interface)

Produces The Highest Quality Picture

   

- HDMI carries both high definition video and audio signal.
- Unlike DVI, HDMI is capable of two-way communication so that DCT's and TV's can communicate with each other. This two-way communication means that a digital receiver and a TV can automatically learn what each other is capable of and then adjust to the best possible viewing and listening experience.
