2. Rules Wizard Initiates
Transfer.
When an appropriate
Advanced encoder becomes
available, jobs are pulled from
the database and a transfer is
initiated. The transfer service
streams (via FTP) the asset from
the Profile and creates proxy
assets of all types (depending on
the configured rules) to a
configured storage location. Then
it associates the high-res
material with the proxy assets.
Once the proxy assets have
been created the transfer service
notifies the Proxy MDI.
3. Startup. At server startup, the Rules
Wizard gets from the MDIs a list of the
assets on the Profile system and on the
Proxy system, to account for any assets
created when the server was not
running. The Resolver is updated and if
related assets do not exist as defined by
the Rules Wizard, jobs are created and
stored in the database.
1. High-Res Asset
Created.
The Profile
MDI monitors the
Profile Video Server file
system to determine
when a new asset is
created. When asset
creation is detected the
Profile MDI notifies the
Rules Wizard which
checks to see if the
asset already has mpeg
associated with it. If not,
a job is created and
stored in the database.
