Colorstream is a video-display standard that rose into popularity with the advent of high-resolution applications such as DVD players and High-definition television.

It offers significantly higher resolutions then composite, RF, or S-Video. It also provides a theoretically more direct path from the source to the display, with less up, down, and signal conversions. It uses three cables for video only, as opposed to the one cable that the majority of alternative formats require, and is available on most of the newer extended definition displays, and roughly all DVD players currently produced. If practical, it is the preferable way to connect High-Resolution devices such as a DVR or a DVD player to a TV if a DVI or other digital input is not available. It is currently regarded as the highest quality analogue connection into the standard high definition TV.
