description

UNSW have released a world first solution allowing students, staff and faculty alike to publish media to iTunes, YouTube, and the unswtv video portal. Join us for an IA war story about how we rationalized these disparate publishing models into a single unified information architecture, allowing users to publish everywhere without having to understand the intricacies of each media destination.

Mass Transit

•Metadata suitcase–“upload templates”

•Use cases examples–mass migration of media from existing source–class assignments submission–regular podcast broadcast

Delivery: There & back again...

Many Moving Parts

• File Storage– Pushing files around infrastructure (secs-hours)

• Transcoding (Autobot)– multiple formats, bottlenecks; (mins-hours)

• iTunes U– webservice (secs-minutes)– can go offline or fail to respond

• YouTube– sFTP for file transfer (secs-hours)– transcoding (mins-hours)– webservice (GDATA) to confirm complete (secs)
