Each sensor only records the information on a light color. Then just saving and restoring the three RGB components of a color monitor that supports three RGB inputs: there are three signals instead of one. Not only should they triple all cable connections between devices, but also triple the recording tracks on a VCR, triple all online videos and games production equipment.
The challenge was to create a single signal encompassing three different information, and should not be mixed prior to treatment by the receiving station. The challenge was also to maintain full compatibility with the black and white positions still present in homes. Researchers are worked in order to create a video signal including red, green, blue, and black and white in the same "pipe" without them mingle.
The cameras, which function as an inverted TV also adopted this interlacing scan. As regards, the first half of an image, a 1st shot defines all the odd lines, and one half frame, a second shooting defines the even lines. The important thing to understand here is that two shots are distant in time (half image).
This represents a difference of 49 lines at 50 Hz and 45 lines for 60 Hz. Those lost lines are necessary, they represent the time required for the electron beam scanning the CRT can be traced from the bottom of an image to the top. This technical problem does not exist with LCD panels and plasma panels, but retained for compatibility.
Free lines are partially taken advantage of: they place the signals teletext, subtitling and also the time-code of professional video equipment. There are two scanning frequencies of the image: The vertical scanning, which takes place from top to bottom is used to compose the image. It is done 50 or 60 times per second.
The horizontal scanning, that is from right to left for each line of an image. The horizontal scanning frequency is equal to frequency multiplied by the vertical number of lines divided by two due to interleaving. This result is not due to chance. If horizontal frequencies are almost the same at 50 Hz and 60 Hz is that it allows to use the same circuitry pan, thus saving money.
An encoded signal of the kind is stated in a composite video signal, because it contains several different types of sources. Video standards use the composite range from U-MATIC / U-MATIC SP HSV through the 8mm or Video 8, Betamax, the VCR or the V2000. In view of damage caused by coding, it became urgent to absolve production. In the early 1980s, Sony devised a video format with separate components consisting of several distinct signals conveyed by separate cables: Betacam / Betacam SP.
To remain compatible with black and white, the company carefully avoided RGB, and naturally selects a format containing the Y, plus information conveyed by two chrominance signals U and V (also known as Cr and Cb). These components are connected by formulas U = R - Y and V = B - Y, where Y = + 0,30R 0,59V 0,11B + (the coefficients being different according to the coding used). This transformation from RGB to YUV is called mastering. Metal stamping is a simpler coding operation that generates no degradation, while offering the advantage of compatibility Y.
