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 reads the mpeg from the
stored location and transcodes it into
thumbnail, storyboard, and RealVideo
formats (depending on the configured
rules), which are then written back to
the same location as the original mpeg
file.
1. Notification of new
mpeg.
In the previous
diagram, Ingest 1, proxy
mpeg is created. Ingest
Control then notifies the
Proxy MDI of the
presence of the new
mpeg. The Proxy MDI
then notifies the Rules
WIzard, which checks
to see if the asset
already has thumbnail,
storyboard, and
RealVideo formats
associated with it. If not,
a job is created and
stored in the database.
