Who discovered component video?

Answer 1

Component video was a development rather than a discovery. The introduction of color television in the US and the UK was conditional on the color system being compatible with all existing telelvisions. All monochrome TVs would still be able to display color broadcasts, but in black and white. This was done because viewers would not be prepared to immediately purchase new televisions as color was introduced. In order to make color compatible with black and white, an encoding scheme was developed so that two separate color signals were superimposed on the black and white image. Black and white receivers could ignore the color information and color receivers would decode the color signals. For production purposes, the black and white signal and the two color signals needed to be separate, leading to the "component signal". The three wires carried all the information needed and could be combined into a composite signal when required. In recent years, component has become commonplace in domestic equipment. It is worth noting that the original color encoding schemes introduced in the 1950s and 1960s are still in use today, virtually unmodified from the original specification. Furthermore, digital signals used today in studios are nothing more than a digital version of the component signals used in analog systems, allowing broadcasters to convert from digital, to component, to composite without needing to interfere with the signal content itself.
