Color Signal Transmission

The color video signal contains two independent information, that of hue and saturation. It is a difficult matter to modulate them to one and the same carrier in such a way that these can be easily recovered at the receiver without affecting each other.

COLOR SIGNAL TRANSMISSION

 

The color video signal contains two independent information, that of hue and saturation. It is a difficult matter to modulate them to one and the same carrier in such a way that these can be easily recovered at the receiver without affecting each other.

 

The problem is accentuated by the need to fit this color signal into a standard TV channel which is almost fully occupied by the ‘Y’ signal. However, to satisfy compatibility requirements the problem has been ingeniously solved by combining the color information into a single variable and by employing what is known as frequency interleaving.

 

 

(In the CCIR PAL I standards the picture and sound carrier are 6 MHz apart and the channel bandwidth is 8 MHz. The only difference between PAL-B and PAL-G is in the channel bandwidth)

 

PAL-B with channel bandwidth of 7 MHz does not provide any inter-channel gap, whereas PAL-G with channel bandwidth of 8 MHz provides a band gap of 1 MHz in-between successive channels.
