Animation Fill
Imagestore HDTV has a self-test programme to verify the correct installation
of store memory modules. The Animation Fill self test will generate an
animation sequence to fill the store memory module of the given layer.
The animation is no different from one loaded from a file, and in particular:
♦ For the animation to fill the store, either (i) the Image Load Mode
must
be Clean Load
, or (ii) any existing image on that layer must be unloaded.
♦ For the animation to be visible, the layer must be cut up.
♦ The animation can be repositioned, masked, and unloaded in the normal
way.
The animations are loaded via the following menu items:
Setup > Self Tests > DSK 1 > Animation Fill
Setup > Self Tests > DSK 2 > Animation Fill
The animation is in the form of a progress bar, filling the image from left to
right with a green background, keyed as a ramp, and repeating continuously.
♦ If the green traverses 1 column, the unit is licensed for 64Mb.
At 59.94 fields/s, the animation will run for 2.14 seconds.
♦ If it traverses 2 columns, the unit is licensed for 128Mb.
At 59.94 fields/s, the animation will run for 4.28 seconds.
♦ If it traverses 4 columns, the unit is licensed for 256Mb.
At 59.94 fields/s, the animation will run for 8.55 seconds. The test
loading time is ~25 seconds.
♦ If it traverses all 8 columns, the unit is licensed for 512Mb.
At 59.94 fields/s, the animation will run for 17 seconds. The test loading
time is ~45 seconds.
♦ If the animation is continuous (i.e. without purple frames), then the unit
has the correct store memory module fitted.
Note! Unload the self test animation after completing the test.
