Media-Store

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.

Media-Store Overview

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.

File Formats

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).

Animation Naming Convention

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.

Note:

•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.

Transparency

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, refer to the section “Input BNC Configuration” on page 10.

Loading an Image or Animation by Browsing

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.

To load an image or animation by browsing the file system:
