JVC KM-H2500U User Manual

This chapter describes the Media-Store operation. 
Your switcher has 2 Media-Store channels which 
allow you to display 2 images or animations 
(composed of a sequence of images) on-air 
simultaneously.

Images and animations are assigned unique Media 
numbers that allow the switcher to identify them. You 
can load images and animations into Media-Store 
channels in one of two ways:

• By browsing the internal file system of the switcher 

or USB drive.

• By using the Wipe Pattern buttons to specify Media 

numbers.

Images must be 24-bit or 32-bit (24-bit image plus 
8-bit embedded alpha channel) Targa files.

Animations must be Targa sequences, a collection of 
individual image files (one file per animation frame).

The individual files share a common name with a 
sequential frame number appended at the end as 
follows:

• Anim_001.tga
• Anim_002.tga
• Anim_003.tga
• ...
• Anim_100.tga

These files are treated as a 100 frame animation 
named Anim.

• Files must be numbered sequentially.
• File numbers must be preceded by an underscore 

“_” character to be recognized as part of an 
animation.

• All files in an animation must be stored in the same 

directory.

The switcher supports images and animations with 
embedded transparency. You must set the second 
Media-Store channel as the alpha channel of the first 
Media-Store channel to have the switcher 
automatically load image data and transparency data 
into the appropriate Media-Store channels.

For More Information on...
• Associating alpha channel inputs with video inputs, 

You can browse the file system on the switcher or a 
USB drive to select images and animations to load. 
You must use this method the first time an image 
or animation is loaded in order for it to be 
assigned a unique Media number.

If you are loading from a USB drive, insert it into 
the USB port on the switcher.

Press and hold SHIFT on any bus. If you use the 

Program bus or on-air Key bus, you will affect 
on-air images.

Media-Store channel to load into.
