You can turn Closed Captioning on or off for individual Video Streams by using the <CC> button in the lower left portion of the viewer window. If the stream is not configured for Closed Captioning the CC button is greyed out.
The default Closed Captioning setting (on or off) can be set from the Preferences section of the MIS tool bar. This is explained in the Tools section of this manual.
MIS always captures the CC data if the admin has configured it to do so, which allows you to go to any point in time and view it. When MIS displays the Closed Caption text, it conforms to the SMPTE profile of W3C Time Text Markup Language which preserves the: position, transparency, font, color, and timing.
