Television: What do these color bars mean?
You have probably already seen an intriguing fact on your television. With each bug in the signal or possible failure, colored bars appear on the screen. But do you know its origin? We take stock!
Where do those colored bars on the TV screen come from?
Since the advent of televisions, test charts have always existed. Indeed, this type of colored image was used to adjust the television display which then had an antenna at that time. The most famous of these images? The one created in 1938 by a company that marketed electronic products called RCA. Later, the appearance of a color television will lead to a change in the design of these models.
Invented by Norbert Larky and David Holmes… This is a very common television test pattern in countries that use the standard NTSC video format. It’s one of the most popular.
The role of these colored bars!
These colored bars had in fact the task of calibrating the signaling and adjusting the receiver in terms of light and chromatic palette. A rather simple design that features only vertical lines. In this format, there are seven color bars at 75% intensity (gray, yellow, cyan, green, magenta, red and blue). The rest of the picture is made up of calibrations and setups so you can adjust them to the TV.
These sights began to gradually disappear over time. Television technology has come a long way, advancing by leaps and bounds in recent years. However, some channels still use them sometimes, only to mark an end of transmission.
