Lectopia Support _at_ OIT

• DMS partners with 3 other OIT units to provide
  Lectopia support for DukeCapture

• OIT Collaborative Systems
• OIT CDSS (Centralized Desktop and Server Support)
  
• OIT Help Desk

4
Digital Media Solutions

• DMS provides management for the overall project
  and central admin for accounts
• Works closely with site admins to make sure
  youre getting what you need from the system
• DMS works with UWA on troubleshooting,
  customization feature enhancements
• We are paying 10,000/ yr for support
• Examplescustom auth module, high quality VGA,
  RealMedia
• Currently no central licensing costs, which means
  youre essentially just paying for the machine
  plus support

5
OIT Collaborative Systems

• Provides administration for back-end systems
• Central Lectopia server
• Bank of processors
• ftp and delivery servers
• Various supporting applications (MySQL, Lasso,
  Cleaner, Shibboleth, etc.)
• Provides hardware and software installation,
  upgrades, maintenance, and troubleshooting
• Provides administration for OIT streaming servers
  used to deliver Lectopia content. Lectopia
  content is published to afs directories
  associated with DukeStream--/afs/acpub.duke.edu/pr
  oject/media/ilecture

6
OIT CDSS (Centralized Desktop and Server
Support)

• Works with DMS to create functional builds for
  Lectopia digitisers.
• CDSS orders new units and installs the builds
• CDSS delivers new digitisers and registers them
  on the network
• CDSS maintains the units for a 3-year support
  period, which includes software patches and
  updates, replacement of hardware covered under
  warranty (3 years for the computer and associated
  hardware, and 1 year for capture cards)
• CDSS assists DMS with triage for problems with
  the digitisers

7
OIT Help Desk

• Provide assistance routing, tracking triage for
  support requests related to Lectopia
• Support issues need to be initiated with a call
  to the Help Desk
• If the person initiating the call is a Lectopia
  user, that support request will be routed to the
  Site Administrator associated with the unit/s
  involved
• If the person initiating the call is a site
  administrator, based on input provided the call
  will be routed to DMS or to CDSS.

8
New Venue Setup

• CDSS orders the units, installs a disk image
  developed in collaboration with DMS, delivers
  the units, and works with customers to enable
  network access for the system.
• Before we come out we need to obtain a fixed ip
  address. The systems come with a fixed address
  in place, but for networks not managed centrally
  through OIT, we will need to involve your
  network administrator.
• We deliver the box to you and walk you through
  the set-up of your venue in the Lectopia admin
  interface.

9
Getting Started

• Creating a new unit
• Units are containers for Lectopia recordings
• Creating a recording schedule
• Recording schedules are the mechanism for
  creating recordings and associating them with
  units

10
Creating a New Unit

• Units can correspond to an official course and
  can be named and scheduled accordingly. Or they
  can designate a group of recordings you define,
  such as a guest speaker series, or your own
  personal tests.

11
Creating a New Unit
12
Creating a New Unit

• We will need for you to take out a remedy ticket
  requesting a new afs volume for each unit before
  recording lectures. Otherwise the lectures
  will be archived to the top level ilecture
  directory in afs. To create a volume we will
  simply need the unit name(s) and unit code(s) of
  your unit(s).
• We need a couple of days of lead time to set up
  new units
• Units where possible need to be set up on a
  semester-by-semester basis to keep storage
  manageable

13
Creating a Recording Schedule

• Once youve set up a unit, the next step is to
  create a recording schedule.
• You can schedule a single recording or up to a
  years worth of classes.
• You can also set up a digitiser to function in
  manual mode. When you do this, the digitizer
  essentially creates a recording schedule on the
  fly for a single recording.

15
Lectopia Core Components

• Lectopia handles the capture, processing, and
  delivery of content in the system via
• Recording settings
• Compression settings
• Delivery settings
• Delivery groups

16
Recording Settings

• These are basic capture settings used on the
  digitizer machine itself.
• Raw files are captured, and then immediately
  uploaded via sftp to a remote bank of processors
  for compression
• DMS enters recording settings into the system. We
  will work with site admins to develop custom
  recording settings if needed.

17
Recording Settings
18
Compression Settings

• These are Cleaner settings files (.xml) that
  dictate
• Media type (Quicktime, .mp3, .mp4, .rm, .wmv,
  etc.)
• Data rate bit depth
• Frame rate
• Movie pixel dimensions
• Again, DMS creates these, and will work with you
  to customize these according to your needs

19
Compression Settings
20
Delivery Settings

• A Delivery Setting is a compression setting plus
  info about
• Where to put the file
• How to deliver the file
• How to package the file

21
Delivery Settings
22
Delivery Groups

• Delivery groups are collections of delivery
  settings. I.e., you can turn a single lecture
  into a series files, each fine-tuned for a
  different audience.

  iTunes_at_Duke for your content
• Specify a delivery setting for which iTunes Music
  Store Cupertino is the server

Issues of Note

• Selecting digitizer inputs
• Digitiser Virus protection issues

35
Selecting digitiser inputs

• Selecting inputs in Digitiser Video Source
  Window
• Scenario 1
• A single VGA capture card installed
• gtVideo Device 1 must be the Vision RGB Pro card
• Scenario 2
• A single composite video capture card installed
• gt Video Device 1 must be the composite video
  capture card
• Scenario 3
• Two video capture cards
• A composite video capture card installed
• A VGA capture card installed
• gt Video Device 1 must be the composite video
  capture card
• gt Video Device 2 must be the Vision RGB Pro card

36
Virus protection issue

• Digitizers dont currently have virus protection
  installed. This is because
• a) the developers of Lectopia recommend that it
  not be included because of performance issues
• b) the systems are locked down, and no viruses
  should be introduced to the system - unless the
  system is already compromised in which case, the
  viruses are moot.
• This is one reason we want systems to be locked
  down
• We will be researching the addition of virus
  protection to future digitiser builds
