Abstract
A color television receiver includes a picture-in-picture processor and a variable filtering circuit for imparting a 'slope type' filtering characteristic to the chrominance component of displayed signals when the main picture being displayed is from a tuner video source and for imparting a 'hay-stack' type filtering characteristic to the chrominance component when the main picture picture being displayed is from an auxiliary video source thereby providing an effective reduction in the visibility of chrominance signal sideband amplitude errors when displaying picture-in-picture images from different types of sources.
