Conversion software allows large animations and images to be saved across
multiple floppy disks (span files .oxm), using loss-less compression to reduce
the number of disks required.
Miranda Technologies Ltd also provides an image transfer and management
system for Imagestore HDTV. The Media Distribution System(MDS) uses a
local area network to connect the workstation to a number of Miranda
Technologies Ltd's image and audio insertion products. Details of MDS are
contained in a separate manual user guide.
Image Editing
The image editor permits an operator to position an image/animation (both
horizontally and vertically), mask the image/animation and adjust the clip,
gain and transparency levels prior to transmission.
Transmission
Once prepared, an image/animation can be saved in the image library and
sent to air using fade and cut transitions.
Animated Images
Imagestore HDTV provides image animation, for applications such as
moving logos, messages and emergency images. The image motion system
provides storage and live playout for up to 40, (optionally 400, 1000 or 2000)
full, or part-screen images of variable duration.
The maximum animation length is dependent upon both the screen-size of the
images and the playout memory installed in the Imagestore HDTV.
There are two video stores, which may be used to hold text, stills or moving
logos. The images may be any size up to full screen. Stored images and their
associated keys are stored and processed at 10 bit resolution. (Unless the
image is stored without key to save space in which case it is stored at 8 bit
resolution.)
The time for larger animations, up to full screen, are reduced proportionally
to the area used. Areas are evaluated each frame so bugs may change in size
with no penalty.
