7700 MultiFrame Manual 7736CEM Composite Encoder with Monitoring 8.8.2. Loss of Video The user can either have the output video go to black or freeze the last good video picture at the input with this control. 8.8.3. Genlock Source This parameter allows you to select the reference video for the frame synchronizer output timing. The reference may either be an externally supplied colour black or you may use the input video as a reference. -
Page 84: Ntsc Colour Phase
7700 MultiFrame Manual 7736CEM Composite Encoder with Monitoring 8.8.7. NTSC Colour Phase With this parameter, you can set the colour field phase of the output video with respect to the Genlock reference input when operating in NTSC/525 video mode. The correct value for this register will depend on the reference to output video phase. If the output video is later than the reference video, but less than one field, then setting this control to “0”... -

NTSC Setup Pedestal Composite NTSC analog video may have a 7.5 IRE pedestal while 4:2:2 SDI video does not. This control, when set to On, will add the pedestal and re-scale the video accordingly. The setup pedestal should not be present on composite video when operating in Japan. -
Page 89: Composite Display Mode
7700 MultiFrame Manual 7736CEM Composite Encoder with Monitoring Blank is used to remove captioning from line 21. Note: The captions are Blanked from the main, high quality, output only. This will allow the monitoring of upstream captioning on the monitoring output even when it is not desirable to have them passed downstream on the program video. -

Page 92: Mode
7700 MultiFrame Manual 7736CEM Composite Encoder with Monitoring 8.12.5.3. Mode This parameter determines the display properties of the status window. When it is set to Normal the status window will use the text window properties. When it is set to Fault, items in the status window that have been selected for fault generation using the Fault Traps tab will use the Fault window properties when the fault is active. -
Page 93: Frame Status Trigger
8.13.1. Frame Status Trigger The 7700 frame has a global status line that any card can pull active. With this control, you can select the condition for the card to cause the line to go active. Also included on the frame status signal is card power supply monitoring. -
