In the Horizontal Blanking case, stripping removes any embedded audio data in the
blanking area of all the video.
5. Use the Image Starts knob to select the image start point. As the line number
increases, the bar graph displays additional boxes with line numbers to reflect this
change. You can then pass or strip these lines as required. Refer to the following
diagram.
The bottom knob controls the line number that the switcher considers as the first line of
active video (i.e. the line on which the image starts). By default this is the first line after
the vertical blanking. In some cases it may be desirable to protect the first few lines of
normal video from being modified by the switcher. For example: In 525 systems closed
captioning may be present a couple of lines past the vertical blanking.
• To prevent keying etc. from destroying the closed captioning of a background
selection, use the
Image Starts knob to adjust the first line number after the closed
caption line. The bar graph will now display additional boxes for the lines that the
switcher will protect (refer to the following example).
