Processing of image data
∫Management of the image memory
≥Memory capacity
Images transmitted from the PC are stored in the
NTSC: 30 pages
(1 page = amount of memory required for 1 image on Monitor 1 screen)
PAL: 26 pages
The image memory is divided into separate areas for Title data and IntVideo data and capacity can be allocated freely as required.
≥DIVIDE
The number of memory pages used differs, depending on the number of vertical pixels, however this only applies when images are transmitted as Title data. The memory pages being used can be reduced by adjusting the size of the image for DSK playback, so that a larger number of images can be played back.
| Number of vertical pixels | Number of memory pages used |
|
|
|
NTSC | 1 to 60 | 1/8 page |
|
|
|
| 61 to 120 | 1/4 page |
|
|
|
| 121 to 240 | 1/2 page |
|
|
|
| 241 to 480 | 1 page |
|
|
|
PAL | 1 to 72 | 1/8 page |
|
|
|
| 73 to 144 | 1/4 page |
|
|
|
| 145 to 288 | 1/2 page |
|

| 289 to 576 | 1 page |

<Notes>
≥When the vertical position is set, images with a small number of vertical pixels can be played back on the lower part of the screen. This is effective for DSK playback of telop or logos at the lower part of the screen.
≥IntVideo data always use one memory page, regardless of the image size.
