Abstract

In the picture-in-picture (PIP) section of a color television receiver, color burst pulses for separating the color burst of the video signal corresponding to the main picture are generated. Responses to planar synchronization pulses received by the receiver's tilting section are used to obtain the subcolor carrier signal for remodulation in the baseband color component corresponding to the mini-picture interpolation. Planar synchronization pulses related to tilting are then passed to the PIP section to properly position the mini-picture relative to the main picture. Even after planar centering adjustments are made to optimize color burst pulse positioning, a burst gate pulse delay control signal is generated. This is in response to the positional relationship between the planar synchronization pulses related to tilting and the planar synchronization pulses of the video signal corresponding to the main picture. The color burst pulse delay signal is usefully generated by the micro-base processor television control unit, which receives both the planar synchronization pulses related to tilting and the on-screen video pulses for sequential tuning control.
