    • A vertical blanking interval (VBI) signal testing tool captures, isolates, and analyzes a VBI signal to determine the quality of the VBI signal or signal source. A digitized VBI signal may be received and analyzed according to industry standards. The VBI signal is examined using thresholds, threshold points, and other points as a way of discerning waveforms in the signal and their individual characteristics. Thereafter, deviations of the VBI signal from industry standards are logged or displayed for review. One feature of the tool records captured VBI data to a persistent storage medium, thereby allowing post-processing of the VBI signal at another time and/or another location. An exemplary analysis program can read the recorded VBI data from the persistent storage medium and perform tests to determine the quality of the VBI signal or signal source. VBI signal translations are also contemplated.
    • 垂直消隐间隔(VBI)信号测试工具捕获,隔离和分析VBI信号以确定VBI信号或信号源的质量。 可以根据行业标准接收和分析数字化的VBI信号。 使用阈值,阈值点和其他点来检查VBI信号作为识别信号波形及其各自特征的方式。 此后,将记录或显示VBI信号与行业标准的偏差以供审核。 该工具的一个特征将捕获的VBI数据记录到永久存储介质,从而允许在另一个时间和/或其他位置对VBI信号进行后处理。 示例性分析程序可以从永久存储介质读取记录的VBI数据,并执行测试以确定VBI信号或信号源的质量。 也可以考虑VBI信号转换。
