Video connectors are the standard jacks used to connect video components to each other. These connections are used for transferring video signals from a source (like a DVD player) to a monitor. Input connectors allow information to be transferred to the device from another device.
Component Video will provide the best picture for DVDs as they are encoded in component video.
S-Video has a special four-pin connector that carries the chrominance (color) and luminance (brightness) portions of the video signal separately, this improves color accuracy and reduces distortion.
Optical/ Coaxial digital inputs are used to receive AC3, Dolby Digital and DTS audio signals up to 6 channels (5.1). A special feature of these inputs is an immunity to radio frequency (RF) interference. Also handy is the ability to use an easy single cable connection.
