The FBAS composite (color image blanking synchronous) signal is the standard transmission signal in the video field which is understood by all devices. Unfortunately, it is also the signal with the poorest quality, because here the brightness signal Y (luminance) and the color signal C (chrominance) together with the synchronization signal are transmitted interlaced over one line.<\/p>\n

Separating the two signals in the receiver leads to more or less pronounced cross-color or cross-luminance effects, depending on the quality of the comb filter used. In this case, a small checkered jacket shimmers in all colors.<\/p>\n

Note: The FBAS composite signal is output either via a yellow Cinch\/RCA socket or via the SCART connection socket.<\/p>\n

S-Video – Y\/C <\/h2>\n

An S-Video Y\/C signal is not a broadcastable format because the brightness signal Y (Luminance) and the color signal C (Chrominance) are transmitted separately over two cables. Because the signals do not have to be separated from each other in the receiver, the cross-color or cross-luminance effects that occur with FBAS transmission do not occur.
This transmission system is often wrongly called S-VHS transmission. S-VHS is a similar technique which records the brightness signal Y (Luminance) and the color signal C (Chrominance) separately in S-VHS video recorders, but has nothing to do with the transmission of video data.<\/p>\n

Note: The S-Video Y\/C signal is output either via an S-Video Y\/C – Hosiden socket or via the SCART connection socket.<\/p>\n

RGB <\/h2>\n

The RGB (Red Green Blue) signal is not a broadcastable format, because here the colors are separated according to the three basic colors and 3 cables are transmitted. The Syncron signal can be transmitted in different ways. Mostly the FBAS signal is used for this, which is also transmitted with a SCART connection, this is then called sRGB (occasionally also called RGBS or RGBY). The Syncron signal can also be on the green color channel, this is then called RGsB. Or the Syncron signals are transmitted completely separately on separate lines as H-Sync (Horizontal Sync) and V-Sync (Vertical Sync), this is then called RGB HV.A YUV component connector may also consist of Red, Green, Blue RCA or BNC connectors, and could be mistaken for an RGB connector. These should not be labeled with RGB, but with Y, U (Cb\/Pb) and V (Cr\/Pr).
To make the confusion complete, there are also constructions where the RGB pins are assigned with the YUV signals. So there are devices that output YUV signals via a SCART socket. In this case the Y is on RGB green, the U (Cb\/Pb) on RGB red and the V (Cr\/Pr) on RGB blue.
Note: The RGB signal is output via the SCART connector, or in very rare cases for projector control via 5 Cinch\/RCA or BNC sockets as RGB HV.<\/p>\n

The brightness portion Y (Luminance) is won from the RGB color space thereby as follows.<\/p>\n
