3.2 Detailed control in Gyda mode

All functions of the card can be controlled through the Multicon GYDA control system. The

Multicon GYDA has an information page and a configuration page.

The information page shows a dynamic block-diagram of the board and some additional informative text. The block diagram updates with the board status, showing input signal selected and signals missing (by red crosses over signal lines). nevion.com | 15

FRS-3G-DUAL Rev. B

The information text below the dynamic block diagram lists information not easily conveyed in a graphical manner.

Sync source will indicate either Blackburst or Tri-level sync if a reference input has been detected, and Loss of lock if no reference has been detected.

Electrical input (1/2) will indicate either Signal present or No signal. Signal present merely means that a carrier has been detected, actual video content may or may not be present.

Reclocker (1/2) will indicate either Locked or Loss of lock. Lock means that the module has been able to recognize and lock to the video content.

Input source (1/2) will indicate either Electrical, Generator, or Mute. This is an indication of current input selection. If Generator or Mute is shown, it will either be because the selector has been forced to this selection by the user, or because they have been set as fallback for the electrical input, which is currently not present.

Signal integrity (1/2) is split in three sections. The first will indicate the present input video standard, and the second is an error counter that will count the number of frames with at least one countable error. The third section consists of the individual error bits as reported by the module. A red background color means that this error was detected, and counted. A green background color means that no error of this type was detected. A gray background color means that the user has decided to ignore this type of error.

Phase delay (1/2) displays a recalculation of the phase delay set by the user. The user can set the delay in video lines and/or video samples. The combined setting will be recalculated into nanoseconds and video samples for the current video standard. This can be used as a tool to match up the delays with other types of equipment with different input formats for the phase delay.

Additional video delay (1/2) is simply a reminder of the additional frame delay added by the user. This is usually used to add delay to match the processing time with that of other equipment. nevion.com | 16
