Abstract
When levels of chrominance signals reproduced from a helical scan video tape recorder are controlled, two types of control signals are generated based on a level of color burst signal of the reproduced chrominance signals. One of the two control signals is responsive to relatively rapid level changes, and the other thereof is responsive to stationary errors based on head-tape contacting pressure changes during one revolution of a rotary video head.
