TELEVISION RECEIVER WITH AUXILIARY VIDEO INPUT

摘要

A television receiver responsive to a broadcast television signal in a normal operating mode includes a television signal channel with high frequency peaking circuits, followed by a display driver to which an auxiliary video signal may be applied. A low pass filter is connected between the output of the television signal channel and the display driver, which exhibits a wide bandwidth when the receiver is intended to display auxiliary video information. The bandwidth of the low pass filter is inversely related to the bandwidth of the driver such that the low pass filter exhibits a narrow bandwidth relative to the bandwidth of a wideband display driver.
