CineCast Quad Pro Version 2.6 Installation and User Manual
DECODER Command (45h)
The two output discretes are located on the two 44 pin connector. Each channel
also has a relay contact closure (called Playback Active or Tally output) which is
activated while playback is active.
003B Video Switch: This command controls the vertical interval video switch
between channel pairs. Set bit 8 of command (i.e. 013Bh) to force the video
switch (the switch to occur on the next vertical sync). Video switching requires
both channels to be genlocked to the same genlock source. Command 003Ch can
be used to switch both audio and video. The 32 bits of data determine which out-
put channel is selected:
If genlock is not valid on both channels when switching video, the command will
be ignored and the following error will be returned: “Recovered Error, Genlock
Sync Lost.”
See “Application Note” on page 139 for an example of two-channel playback
using CineCast Quad Pro video/audio switching.
003C Set Audio Channel Selection/Audio Fade: This command controls output
selection for the two outputs (primary and secondary) from four possible sources.
