The Encore system enables you to capture frames into the VP’s three internal frame stores. The “sources” of the frames are the background inputs on each VP (and VPx), or any active layer. Please note:

•For single screen and ScreenPRO-II destinations, you are working with the individual destination’s three frame stores (FG_1, FG_2 and FG_3) as normal.

•For widescreen destinations, even though you are using the frame stores of multiple Processors, you are "operationally" working with only three frame stores (FG_1, FG_2 and FG_3) — each of which captures’s its “slice” of the complete widescreen image.

•For “stack” systems, remember you have six “temp” frame stores available, and your menus will change accordingly:

~Three frame stores are available for the “bottom” stack Processor:

•BG_FG_1, BG_FG_2 and BG_FG_3.

~Three frame stores are available for the “top” stack Processor:

•DSK_FG_1, DSK_FG_2 and DSK_FG_3.

Please note the following important points regarding "stack" configurations:

~In a stacked configuration, you can not capture frames on the bottom ME board of the top VP. This is necessary because the background channels of this ME board are in use, to facilitate the transfer of data from the bottom VP to the top VP — and thus, the channels can’t be used to simultaneously capture frames.
