January 13, 2010
Initial Situation @ Unige
Existing centralized audio and video capture based on hardware capture cards (Optibase)
Existing uncentralized audio capture
Unautomated file upload and metadata completion
Audio and Video capture
Initial Aims
Makes a complete enriched media recording and broadcasting system available
This system allows a speaker to record and archive the whole media: Audio, video and VGA signals
Fully automatic capture
Automatic upload and metadata completion
Human validation & if needed metadata enrichment
Constraints
Teacher has nothing to do in the room
No human resources are needed to produce, edit and catalog the courses
Buildings (uncentralized signals in some cases)
New Global Workflow for 2010
Room Hardware
Software
New scheduler in order to manage 3 differents capture systems (1 interface per building)
Automatic script for file uploading and metadata completion
Adaptation of Mediaserver public catalog to broadcast new formats
Interface for validating file content and metadata
Complete Architecture
Specificities
Automatic courses capture and cataloging
No human resources are needed for captureRequires an installed files validation workflowRequires a good communication between all actors
(teacher, technician, content validator)
Specificities
Uncentralized solution
DisadvantagesA lot of distributed hardware to maintainHuman needs to control room hardware
AdvantagesEconomic (~1700 CHF/Room)Doesn't require centralized signals (e.g. old buildings)
