There are several models for
Central Casting that can be supported with AVECO
automation.
Totally Centralized
A centralized hub develops all playlists
and assembles all media for playout that is then
distributed to spoke stations for on-air broadcasting.
The centralized hub functions as a multiple channel
station that feeds media ready for broadcast to
outlying stations that put the signal on-air.
Some of the content at the hub is shared among
all outlying stations while other portions of
the hub's media is specific to each remote station.
For implementing this centralized model, our products
offer multichannel broadcasting capabilities with
the ability to synchronize media playout from
multiple playlists and simultaneously broadcast
from one source to many. Automation synchronization
with GPS receivers or the station's masterclock
and time managers on each playout channel allow
our systems to account for time delays in transporting
streaming media from the hub to the spoke stations.
Centralized Media with Localized
Playlist and Control
Here, a central hub is used to manage
media while outlying stations develop playlists
and remotely control playout from the hub. The
hub provides a broadcast ready media stream to
the spoke stations that put the signal on air.
Our systems can do this because, in addition to
the capabilities that make AVECO systems suitable
for a totally centralized operation, we can control
devices frame-accurately over WAN networks that
introduce uncertain transmission delays. We can
also implement the mirror image of this configuration
and centralized playlists and control while keeping
the media handling capability at each spoke station.
Cooperating Sites
Here the ability to develop playlists
and work with media is maintained at each location.
AVECO systems, with network transparency, connectivity
over WAN/Internet using TCP/IP and comprehensive
media management, can automatically coordinate
two or more different locations as if they were
one multiple channel operation working in one
building. For the same reasons stated earlier,
each individual location can become the central
hub for the others. Systems and resources can
be shared among facilities. For example, one location
can yield control of router outputs to the sister
station that is using them. Or, one area can delegate
control of its equipment to another. From the
automation's point of view, moving clips among
locations is no different than moving then among
devices in one room except that the transfer takes
longer. Also, AVECO's support of live team work
extends to teams working from different locations
so distance is no reason for a group's stations
not to work together.
Hybrid Configurations
Variations off all kinds are possible
with AVECO automation. Perhaps you would like
to keep the news team on location while all other
departments move to the central hub. Or, you want
local ad insertion to take place at the spoke
stations. No problem. Let us know what you need
and we will configure your AVECO system to do
it.
Additional comments on central
casting
The full functionality of AVECO
automation is available in central casting configurations
as it is for a single location system.
Database configurations: If the
automation system is set-up as one system in a
totally centralized configuration, one database
will manage the entire operation regardless of
the number or servers or TV channels. When automation
systems at separate locations cooperate, each
site will have its own database. These databases
will work with each other to find and track media
and corresponding metadata. When hybrid models
are implemented, multiple databases can be coordinated
or one centralized database can serve the entire
system depending on specific requirements. A full
database mirroring option is available wherever
a database is present.
Playlist discussion: Playlist managers
run on PC automation servers, and playlist browsers
run on disk-less PC terminals. Depending on the
complexity of each broadcast channel, one PC automation
server can host up to 6 channels and their corresponding
playlist managers. The maximum number of channels
for a multiple-server automation system is unlimited
since servers can be added to the system to to
increase capacity. One client terminal can have
access to all playlists on the system as long
as access rights are granted. However, the number
of playlists browsers that can be displayed simultaneously
per PC terminal is limited by the screen space
available at the client. For channels that require
heavy operator intervention, like channels broadcasting
live events or programming that requires many
last minute changes, one or more terminals per
playlist are recommended. If there are a number
of channels playing on full automatic mode so
they can all be managed by a single person, then
the question is many playlist browsers can be
concurrently displayed on single PC. We recommend
from six to a maximum of ten. The internal diagnostic
subsystem for each channel will alert the operator
of any need to take action, therefore, direct
viewing of all playlists is not necessary to ensure
smooth playout of multiple channels.
