Program-Preview Mode - Pinnacle Systems Deko1000 Technical Reference And Service Manual

Program-Preview Mode

In Program-Preview mode, two TARGA 3200 boards are installed in a Deko1000 or Deko550
workstation. The first channel (i.e., TARGA board) operates exactly as in single channel mode.
All I/O, clip processing, effects output, and keying performed by the Inflexion software is
processed by the first TARGA 3200 board. The frame buffer of the second TARGA 3200 board is
used to output the Program-Preview. This output is the static graphic that is displayed on the
Preview window within the Deko1000 or Deko550 software program.
Important: No effects or clips can be output from the second TARGA 3200 board as Program-Preview.
An illustration that is representative of the signal flow for Program-Preview mode processing is
shown in Figure 2-2.
