After clicking on a debug link, the caption text is shown at the top of the screen.
Below that is the Program ID of the content currently playing, as reported by the
DCS in the Content Synchronization Protocol timeline update message. The Fra-
meNum is the edit unit currently being displayed. This is generated by a clock in
the IRC-28C that is synchronized with the DCS using the Content Synchronization
Protocol. The Current Caption TimeIn and TimeOut show the edit unit (or frame)
number when the caption should appear and when it should disappear. These
numbers are calculated from data in the RPL and the timed text files. The playout
ID, TimeIn, and TimeOut for the next caption to be dispalyed are shown next.
The SystemStatus is a hexadecimal number indicating the overall system sta-
tus. The bit assignments in the SystemStatus word are shown below.
