Overview :
This MxMs allows
reading and generating Time Code using TimeCode resources.
> Top
Installation (MXM) :
No Installation.
> Top
Creation (Device) :
The creation of
the device is done through this dialog box :
TimeCode Port: The "Select" button allows
selecting an available TimeCode resource present on the
system.
Positrack burst : If this check-box is
checked, the time indicated in the edit control is used by the
positrack mode of Manager : when the mxm receives a pause in
positrack mode in a task that sends timecode, it rolls this
amount of time before stopping at the time of the pause. For
example, if a cue it at 00:00:04/00 and the burst is 100, a
period of timecode signal between 00:00:03/00 and 00:00:04/00
is sent on the output of the card when the user clicks on this
cue in pause mode.

Commands (List Of) :
Start
Sending Timecode :
Description : Begin to send a timecode signal.
Parameters
Start at [Type : Time] : The time at which the
signal must start.
Synchro [Type :Enum] : The type of intput synchronisation
of the output signal.
Available values :
“Free run” : no syncronisation mechanism
“Video input” : synchronisation to the video input
of the card
Usage : Note
about using Adrienne Timecode Card as a timecode source.
Using video synchronisation, in 25 FPS mode the board
expects to see PAL (25 frames per second) sync signal,
in 30 FPS ND mode the board expects to see NTSC (30
frames per second non drop) signal, in 30 FPS DF the
board expects COLOR (29.97 frames) signal. The board
cannot sense color subcarrier phase, so it cannot do
color framing.
Stop Sending Timecode :
Description : Stop to send timecode signal
and go back to receiving mode.
Parameters : no parameters
Set Timecode
Type :
Description : Set the type of timecode.
Parameters
Type [Type :Enum] : Choice between the two basic
types of timecode.
Available values :
24 FPS
25 FPS
30 FPS DF
30 FPS ND
Usage :
This is the type for sending and for video synchronisation
detection. It is also the type of the variables TimecodeIn
: if the type of input signal differs from the type of
the variable, it is converted.
> Top
Variables (List Of) :
TimecodeIn :
Type : Time.
Description : The value of the current input
signal, when in receiving mode.
TimecodeOut :
Type : Time.
Description : The value of the current output
signal, when in sending mode.
Status :
Type : Enum
Description : Status of the device.
Available values :
“Idle" : stop mode (device is not running).
"Receiving" : receiving mode only (the default mode)
"Sending and Receiving" : sending and receiving mode.
VideoInput :
Type : Integer.
Description : Status of the video input signal
when in sending mode.
Available values :
0 : no signal detected on video input
1 : a video signal is present on video input.
Note
: This variable is only relevant in Video Sync generator
mode (it is reset to 0 in receive mode or in free run
generator mode).
