Compress
The Compress operation compresses the FROM page to the TO
page. The compressed image appears in the upper left-hand
corner of the TO page.
NOTE:
On the Model 3000 the FROM page is the decoded page.
The key from the corresponding FROM page in the Key Store can
be processed in one of three ways.
1. CREATE
This makes a 4x3 key in the corresponding TO Key Store page
that is the same size as the compressed video. Use this option
if the FROM video is a full-screen image. Set up the Frame
Store to output Shaped video in this mode.
2. COMPRESS
Use this option to compress titles and other keys. This
compressws the corresponding FROM Key Store page the
same as the Video Store page.
3. NONE
This selection does nothing with or to the Key Store pages.
When using COMPRESS, it is best to lock the key to the video.
Also, if the edges have blanking the Crop function is useful. It is
also useful to note the repositioning of compressed video will run
in realtime.
NOTE:
Compress works only on still frozen video.
