Sorry. From the current documentation I did not understand that
standard functionality (AUTO_WHITE_BALANCE, DO_WHITE_BALANCE, GAIN)
required a detailed description. A concise description of a color
killer is as follows:
The color killer disables color decoding if a color-burst is not
present in the input signal. This avoids interference showing up as
false color in purely black-and-white broadcasts (one where the
broadcaster does not generate a color-burst).
