Processing of image data
∫ By data type
Image data is processed by the AG-MX70 either as Title
data or IntVideo data, depending on the application. When
image data is transmitted to the AG-MX70, it is necessary to
first select one of these 2 data types.
≥ Title data
Data to be used for DSK playback should be
transmitted as Title data. RGB data and
data are used by Title data. When an image having
an
channel is used, the image is subjected to
transparency processing corresponding to the value
of the
channel. When an image not having an
channel is used, transparency processing is not
performed.
≥ IntVideo data
When the image is to be played back as internal
matte, it is transmitted as IntVideo data. The image
uses only RGB data. As the
transparency processing is not performed.
∫ Display methods
It is possible to select from the following display methods
according to how the image data is to be played back.
≥ STILL
With this method, a single image is played back as a
still image. Both Title data and IntVideo data can be
used. When Title data is used, it is possible to set the
horizontal position and vertical position of the image.
≥ MOVIE
With this method, two or more images are played back
consecutively. A single image is processed as one
frame. It is possible to select from ONCE or REPEAT
playback. Both Title data and IntVideo data can be
used. When Title data is used, it is possible to set the
horizontal position and vertical position of the image.

≥ CRAWL
Two or more images are lined up one after the other
and played back (scrolled) horizontally on the screen.
It is possible to set the direction and the speed for
scrolling. Only Title data can be used with this
method. It is possible to set the vertical position of
the image.

∫ DSK effects
When an image is displayed on (DSK ON) or cleared from
(DSK OFF) the monitor, it is possible to apply dissolve or 2
or 3D transition effects.
∫ Image size
The appropriate size of images for the Monitor 1 screen
differs, depending on the video format setting of the AG-
MX70 and the MX-Navi settings.
NTSC: Monitor 1 screen = 640 a 480
PAL:
Monitor 1 screen = 768 a 576
It is possible to select any image size for playback, however,
if the image size selected is larger than the Monitor 1
screen, only the part of the image that fits onto the screen
will be transmitted and played back.
∫ Image formats supported
It is possible to use the following image formats for playback
with the AG-MX70.
≥ TARGA (.tga)
24 bit/pixel (no
channel) data can be used.
≥ JPEG (.jpg)
≥ BMP (.bmp)
24 bit/pixel (no
A 32 bit/pixel image of the TARGA format must be used
when the image is to be displayed with transparency
processing. When displaying images using either MOVIE,
ROLL or CRAWL methods, it is necessary to use
consecutively numbered file names.
