The 3rd channel is timecode Hours. The 4th channel is timecode Minutes. The 5th channel
is timecode Seconds. The 6th channel is timecode Frames.
Each of the above timecode parameters uses the following DMX protocol:
Synchronizing to the Deck’s Timecode
Catalyst Media Server layers can be synchronized with timecode sent from Sony 9-pin
devices.
Assign the Play Mode parameter of a layer to a DMX value of 103(Sync to Sony 1) to read
the current frame from the Sony 9-pin device. To assign a negative offset, use the In
Frame parameter value and for a positive offset use the Out Frame parameter value.
Syncing ignores the hours setting because a 16 bit DMX value is only able to represent 44
minutes at 25 fps
Example 1
To assign the first frame of a Catalyst Layer’s movie to play at a time code of point 0hr 1
min 30 sec 5 frames:
1. Calculate frame offset:
(1min * 60 * 25) + (30secs * 25) + 5frames = 1500 + 750 + 5 = 2255
2. Set the In Frame value to 2255 and Out Frame to 0.
