A system, method, and apparatus for utilizing a single video input for receiving multiple video format signals in an electronic video receiver. The single video input includes a set of inputs to accommodate a component video signal from any one of a multitude of video components that output video signals in component video format. An input video signal in one of several component video formats provided to the single video input is selected and processed according to its video format. Once processed, the selected input video signal is output as an output video signal of a particular video format. The particular video format is compatible with a video format utilized by an external component.

A television monitor display with video signal processing comprises a source (SM) of a video display signal (Y) including a sync component (S). A video processor (U) is coupled to process the video display signal (Y). A sync separator (SS) is coupled to generate separated synchronizing signals (Sy) from the sync component (S) of the video display signal (Y). A video amplifier () is coupled to the sync separator (SS) and the video processor (U) and generates an output video signal (Ys+) wherein a sync component (S+) of the output video signal is increased in amplitude in accordance with the separate synchronizing signals (Sy) coupled to the video amplifier ().

A system, method and apparatus are provided for generatinga sandcastle signal in a television signal receiver, and utilizing the sandcastle signal during television signal processing. In one form, the sandcastle signal is generated by subtracting a separated synchronization signal of a television signal from a deflection retrace signal of the television signal receiver. In another form, the sandcastle signal is generated in a television and includes subtracting a separated synchronization pulse from a horizontal flyback pulse, a vertical retrace pulse, or a composite pulse formed by summation of a horizontal flyback pulse and a vertical retrace pulse. The sandcastle signal may be utilized by the television signal receiverduring a function of the television signal receiver, such as during a channel change.

A video signal input selector is subject to cross coupling between selectable video signals. The input selector comprises a video amplifier coupled to amplify a video signal selected from said selectable video signals. A controllable switch has first and second elements, the first element receives the selected video and is coupled to signal ground. The second element receives the selected video and is coupled to the amplifier. During a first condition the first element is controlled to be open circuit and the second element is controlled to be short circuit coupling the selected video signal to the video amplifier. In a second condition the first element is controlled to short circuit the selected video signal to the signal ground and the second element is controlled to be open circuit substantially inhibiting the selected video signal from coupling to the video amplifier.
