Previewing Enhancements in the Timeline (Windows Only)
How you preview enhancements in the Timeline depends on the mode of the enhancement: PIP or Overlay. The preview displays graphic images or "snapshots" of the HTML files referenced by enhancements. You cannot click links or otherwise use the HTML image the way you would use an HTML page in a browser. This preview represents how the enhanced program appears when it is broadcast.
  For information about PIP and Overlay modes, see Understanding ITV Modes.
PIP Mode
To preview the sequence with its enhancements, you need to "step through" the sequence by clicking a Step (Jog) button (such as Step Forward One Frame). The snapshot images are not displayed if you click the Play button.
The video image is displayed inside the HTML background based on the size and location of the tv: code. You can modify the size and position of the video. See Changing the Size and Position of the Video Image (Windows Only).
Overlay Mode
Because Overlay mode uses a matte key, you can preview the sequence by clicking either a Step (Jog) button or the Play button.
