Video Input select
The SYNNER-E 3G has the option of either receiving an optical input or transmitting an
optical output once the necessary SPF optical module has been fitted. If the optical receiver
module is fitted the fibre optic I/O input select will allow the video input to be selected
between the input BNC and the optical input.
With the optical output fitted the number of outputs will be reduced from two to one.
Mode selection
Setting the mode to synchroniser will lock the output to the incoming external reference to
compensate for timing delays within the video system. Selecting Delay mode makes the
SYNNER-E 3G become a fixed delay line.
Should the input signal go away the output will be frozen. The ‘On loss of input’ control
allows the user to select the frozen output. The selection is; Last Frame, Black, Blue, or after a
delay of 2 seconds - Delay Then Black, Delay Then Blue.
Output freeze when selected will cause the output to freeze and show the selected pattern.
These are selectable from the following list; the last frame shown, Black Matte or Blue Matte.
Sync override will force the SYNNER-E 3G into delay mode when the external sync is
incorrect.
Video timing controls
In delay mode the video delay is a straight forward fixed bulk video delay that can be adjusted
in samples, lines and whole-frame steps up to a maximum of 3.5 video frames.
When switched to synchroniser mode the initial delay will vary between 0-1 frame depending
on the timing between the input video and external reference. Further fixed delays can then be
added for matching purposes.
The Minimum synchronisation or Dolby E compensation delay allows a further 0.5 frame
delay to be added to the video delay to ensure correct Dolby E alignment. Along with an
increase in the video delay the PCM audio delay will also be further delayed by a similar
amount allowing the user to avoid a potential problem with aligning Dolby E.
Note:
For the relevant progressive video standards two video frames are the length of one
interlaced frame. The sample and line control will only make adjustments of one frame of
either progressive or interlaced video.
