ABSTRACT:
A television signal receiving apparatus having a first input for receiving a composite video signal and a second input for receiving a direct-drive RGB signal includes an electronic switching circuit for automatically switching between composite video and RGB modes of operation. The switching circuit is responsive to the presence of the sync component of an RGB signal at the second input for automatically establishing the RGB mode of operation wherein only the input RGB signal is used to form the image display and is responsive to the absence of the sync component of the RGB signal at the second input for establishing the composite video mode of operation wherein the composite video signal at the first input is used to form the image display. Provisions are included for developing an override signal for allowing the development of a mixed mode image display.
