Media-Store
Media-Store allows you to load stills, animations,
or audio from the hard drive and make them
available as a source on the switcher. Each ME
has 2 channels of audio and 4 channels video
Media-Store.
Keep the following in mind:
Keep the following in mind when you are using
the Media-Store:
• If you know the number of the still you want
to load, you can select the crosspoint button
mapped to the still-store channel on the ME,
and then enter the still number on the
keypad on the Global Memory module.
• You can clear the still currently loaded into
a channel by selecting
0
as the still number
you load from the keypad on the Global
Memory module. This is the same as pressing
the
Eject
button.
• If you are loading an Auto Key (PNG or TGA
with alpha) into a media-store channel, you
must have another media-store channel
associated with the current one to load the
alpha into.
• Corrupt files are shown with the warning
Not a valid image format
and should be
deleted from the switcher.
• Using a third-party application to upload,
edit, or move media items or directories on
the switcher can cause the permissions to
those files or directories to be set incorrectly.
Use the Media-Store Permissions feature
from the Web UI to clean the permissions.

File Naming
The file name can be up to 32 characters in
length, but should be up to a maximum of 12
characters, so that it can be displayed on the
menus properly. The name can contain letters,
numbers, spaces, dashes, underscores, and,
periods, but should not contain symbols.
If you are naming an animation, each file must
be numbered in the sequence that it will play
out. The following restrictions apply to file
names for animations:
• Each file must use a 2-digit to 5-digit number,
including all the leading zeros.
• Each file in the sequence must have the same
numbering scheme.
• The first file in a sequence must be numbered
0.
• The file name and number must be separated
by an
_
.
• Audio files and video files must have the
same name to be associated with each other.
For example, a 90-frame animation would start
with
Anim_0000.tga
and end with
Anim_0089.tga
Media-Store Audio
Audio can be added to the playout of a Media
-Store channel either by loading the file directly,
or by associating the audio file with the video
