摘要： CW lock is conducted with less manual operation. A first input 22 receives a black burst (BB) signal from a key TV station. A second input 30 receives a continuous wave (CW) signal having an accurate, known frequency. A phase adjust signal generator 24 generates a reset signal having a known phase relationship with regard to the key TV station BB signal. The reset signal is used as a phase adjust signal. A PLL 32 receives the CW signal to provide clock. A counter 34 receives the clock and provides a frame pulse signal for synchronizing the key and local TV signals at a local TV station wherein the BB signal of the local station may be derived from the frame pulse signal. The counter 34 uses the reset signal to adjust the phase relationship between the key TV station BB signal and the frame pulse to a desired phase relationship based upon the key TV station BB signal.

摘要： A user can select an output desired video test signal of a desired video format for a video test signal generator by fewer operations. There are two modes; format priority mode and test signal priority mode. If the user starts the video test signal selection, lists of video test signals and/or video formats are displayed on a display screen. If the user selects a video test signal name on the screen, the process enters into the test signal priority mode and a list of video formats that have the selected test signal is displayed. The user can select a desired video format to determine the output video test signal of the desired video format. At this time, the user may change the video format as many times as needed without changing the selected video test signal. If the user wants to select another video test signal of the selected video format, the user selects the desired video format possibly in combination with a control key on an interface of the generator and then the process jumps to the format priority mode. In the format priority mode, a list of video test signals having the selected video format is displayed. The user can select a desired video test signal to decide the output video test signal of the selected video format. If the user again wants to select another video format of the selected test signal, the user selects the desired video test signal possibly in combination with the control key and then the process again jumps to the test signal priority mode.
摘要翻译：用户可以通过较少的操作为视频测试信号发生器选择期望的视频格式的输出期望的视频测试信号。有两种模式; 格式优先模式和测试信号优先模式。如果用户启动视频测试信号选择，则在显示屏幕上显示视频测试信号和/或视频格式的列表。如果用户在屏幕上选择视频测试信号名称，则进入测试信号优先模式，并显示具有所选测试信号的视频格式列表。用户可以选择所需的视频格式来确定所需视频格式的输出视频测试信号。此时，用户可以根据需要改变视频格式多次，而不改变所选择的视频测试信号。如果用户想要选择所选择的视频格式的另一个视频测试信号，则用户可能与生成器的接口上的控制键结合选择所需的视频格式，然后处理跳转到格式优先模式。在格式优先模式下，显示具有所选视频格式的视频测试信号的列表。用户可以选择所需的视频测试信号来确定所选视频格式的输出视频测试信号。如果用户再次想要选择所选择的测试信号的另一种视频格式，则用户可能与控制键组合地选择所需的视频测试信号，然后再次跳到测试信号优先模式。
