摘要： 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.

摘要： A system, method and apparatus are provided for generating (98) a sandcastle signal in a television signal receiver (90), 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 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 receiver (90) during a function of the television signal receiver (90), such as during a channel change.
摘要翻译：提供了一种系统，方法和设备，用于在电视信号接收器（90）中产生（98）沙堡信号，并且在电视信号处理期间利用沙堡信号。在一种形式中，沙堡信号是通过从电视信号接收器的偏转回扫信号中减去电视信号的分离同步信号而产生的。在另一种形式中，沙电信号在电视机中产生并且包括从水平回扫脉冲，垂直回扫脉冲或由水平回扫脉冲和垂直回扫脉冲的总和形成的复合脉冲中减去分离的同步脉冲。在电视信号接收器（90）的功能期间，例如在频道改变期间，沙堡信号可以被电视信号接收器（90）利用。
