6.6.2 Full Slate
The AVP 4000 allows the user to upload a full video slate (similar format to the Logo
file) which will be displayed on the full screen before being encoded.
The Slate can be selected as a Source, for testing purposes, or as an apology slate
when the video source is lost on the incoming SDI input.
The Slate is the same format as a Logo file and can be created using the Logo
creator utility. Only OSD files of type OSD6 are supported on the AVP 4000.
Note: The encoder supports Full Slate for a full resolution screen; however, there
is a limit for storing the OSD6 Slate file and the limit is 3 Mbyte.
6.6.2.1 Advanced Slate Display Options for the EI9001 and EI9001T
On EI9001/EI9001T Cards, the slate can also be displayed automatically when
certain options are enabled on the Video Component Input tab.
Unless otherwise specified, the following instructions assume each of these features
are enabled in isolation, although they may of course be combined with logical
consequences.
6.6.2.1.1 Display Slate after Sensitivity Delay
This feature monitors the Video Input Lock also displayed on this tab. The
selection made in Output on Video Loss governs the immediate response of the
encoder to the loss of lock. Sensitivity Delay defines a hysteresis for slate display.
The delay is relative to the loss of lock but with a variance of +/-2 seconds. If for
example, Output on Video Loss is set to Freeze Frame, upon loss of lock, after
the encoding delay, the output video will freeze, and Sensitivity Delay seconds
later, +/-2 seconds, the slate will be output, unless the lock was reacquired in the
meantime. The same Sensitivity Delay provides hysteresis for slate removal.
