Media-Store
Media-Store allows you to load stills or animations from
the hard drive and make them available as a source on
the switcher. The switcher provides two types of
media-store, ME-Store and Global-Store.
The Global-Store consists of up to 4 dedicated channels
of media-store that are available as inputs to all MEs and
Aux Buses of the switcher. The fourth channel of
Global-Store can be enabled from the Personality menu
(Global-Store 4 Mode). All channels can be used
independently, or two can be tied together to provide
separate ll and alpha channels. The 4 Gigabytes of
Global-Store cache is provided from Frame CPU board.
The ME-Store option consists of 4 channels of
media-store that are available as inputs to the ME they
have been installed for and can be re-entered onto any
other ME in the switcher. Each ME can have 4
independent channels of ME-Store. The 8 Gigabytes of
ME-Store cache is provided from the 3G Video Processor
board. If the ME is congured as a MultiViewer, the
ME-Stores for that ME are congured as MV-Stores
(MultiViewer Stores) with the same functionality.
In addition to the video channels of the Global-Store, an
additional set of audio channels are provided. The number
of audio channels matches the video channels and can
be increased from three to four from the Personality menu
(Global-Store 4 Mode). Audio and Video playout are
independent from each other.
Media-Store allows you to load stills or animations from
the hard drive and make them available as a source on
the switcher. The switcher provides two types of
media-store, ME-Store and Global-Store.
The Global-Store consists of 1 dedicated channel of
media-store (video+alpha) that is available as an input
to all MEs and Aux Buses of the switcher. The 4
Gigabytes of Global-Store cache is provided from Frame
CPU board.
The ME-Store option consists of 2 channels of
media-store (video+alpha) that are available as inputs to
the ME they have been installed for and can be re-entered
onto any other ME in the switcher. The 8 Gigabytes of
ME-Store cache per ME is provided from the 3G Video
Processor board. If the ME is congured as a
MultiViewer, the ME-Stores for that ME are congured
as MV-Stores (MultiViewer Stores) with the same
functionality.
In addition to the video channels of the Global-Store, an
additional set of audio channels are provided.
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 les 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 les or directories to
be set incorrectly. Use the Media-Store Permissions
feature from the Web UI to clean the permissions.
• MV-Stores are always available when the ME is
congured as a MultiViewer, even if you do not have
permissions to that ME.
• In SD/HD video formats there are up to 4 channels
of Global-Store and 4 channels of ME-Store (per
ME). In UHDTV1 video formats, there is 1 channel
of Global-Store and 2 channels of ME-Store. In
UHDTV1 each channel includes a video and alpha
sub-channel.
• If the switcher is operating in a UHDTV1 video
format, only 1 MV-Store channel (video plus alpha)
is available for each video processor. For example,
for MultiViewer 3 and 4, only MV-Store 3 channels
1 is available.
• Media items should be created in the same color
gamut and dynamic range that they are intended to
be used in on the switcher.
