Streaming vs. Store ForwardConcepts
Common misunderstanding: “Streaming” means “motion video”
“Store-Forward” is a concept to grasp, and many applications and or delivery methods use this approach!!

Main Reasons for Central Video Streaming
Chancellor driven initiative to get DU Athletic live and stored events “on the web”
Faculty wanting to deliver clips and full length material to students (inside and outside of classrooms)
Penrose Library wanting to migrate old media to a digital delivery system

Campus Video Streaming:In-House or Outsource?
Must Have the In-house Expertise for Customization to specific programs
Bandwidth to Classrooms and/or Internet Properly Funded Control of Rights
Content and Authentication Access to Hardware (Cameras, Sound,
Servers, Network, etc..)
![Page 7: 1 Video Streaming Update Chad Burnham & Paul Ross University Technology Services Center for Teaching & Learning September 13, 2005 @ CHECO Conference](https://reader036.vdocument.in/reader036/viewer/2022062721/56649f1b5503460f94c31750/html5/thumbnails/7.jpg)

Campus Video Streaming Outsourcing:
Can be very expensive – usually per flow Can alleviate campus bandwidth
requirements for large events Use Only Certain high profile events Legal Concerns
Fair Use in Higher Education Integration with Courseware packages

DU’s Video Streaming Plan – Phase 1 Phase 1 = FY 2005/06 – NOW! Hybrid product solution - Not fully redundant $70K Budget Pilot to include 3 different components Want to “prove” the technology MPEG 4 (Part 2 & 10 – H.264) is the goal Bandwidth target:
300k for off campus and 1M for on campus If you build it…they will come?
