Abstract
A television signal receiver processes a television signal representing a letterbox image display format with a main image region, and a bar region containing auxiliary information to help convert from interlaced to progressive scanning. The auxiliary information is processed in a signal path including a nonlinear amplitude expander and apparatus for modifying the operation of the signal path as a function of the noise content of the television signal.
