Streaming vs. Store ForwardConcept

Common misunderstanding is that many think “Streaming” means “motion video”

“Store-Forward” is a concept to grasp, and many applications and or delivery methods use this approach!!


Key Standards for DU: MPEG 4 is a ISO/IEC Standard

MPEG-4 part 2 (a.k.a. simple profile) MPEG-4 part 10 (a.k.a. H.264 / advanced profile)

ISMA - http://www.isma.tv/ ISMA Profile 0 (Narrowband/wireless)

MPEG-4 Video Simple Profile 176 x 144 at 15 fps and 64 kbps

ISMA Profile 1 (Broadband) Simple or Advanced Simple Profile 352 x 288 at 30 fps and 1.5 Mbps

ISMA Profile 2 (Broadband – better CODECs) Audio format: MPEG-4 AAC and HE-AAC (“High-Efficiency AAC”),

including 5.1 surround support; Video format: MPEG-4 AVC, also known as ITU-T H.264; Media storage: MPEG-4 and AVC File Format (MP4FF, AVC FF); Media transport: RTP, RTCP; Media control and announcement: RTSP, SDP.

3GPP (Third Generation Partnership Project) Similar to ISMA Profile 0 Designed for wireless handheld devices (phones)

Initial Priority for Central Video Streaming Funding/Project

1. Chancellor driven initiative to get DU Athletic live and stored events “on the web”

2. Faculty wanting to deliver clips and full length material to students (inside and outside of classrooms)

3. Penrose Library wanting to migrate old media to a digital delivery system


Comparing ISMA 2.0 profiles and levels with other standard bodies.

Legal Issues:Fair Use in Higher Education

Digital Rights Management Authentication, Authorization, Concurrent Access Rights DMCA

Campus Video Streaming:In-House or Outsource (or both)? Must Have the In-house Expertise for

Customization to specific programs Faculty, Technical Faculty Liaisons,

Programmers, System Admins, Network Engineers, Programming Engineers, A/V Technicians, Legal, Project Managers

Bandwidth to Classrooms and/or Internet Properly Funded / Hardware / Software


Campus Video Streaming Outsourcing:

Can be very expensive – usually per flow Can alleviate campus bandwidth

requirements Athletic Conference Agreements

Project Overlap? Only Certain high profile events Integration with Courseware packages


DU Considered Many Canned “Solution” Vendors:

V-Brick’s EtherneTV Kasenna’s Mediabase Apple - XServe Platform – QuickTime Server Real Networks - Helix Windows Media Solution Enviro Macromedia’s Flash Communications Server Cisco’s CampusTV (Vaporware? Big Hype @ Educause)

DU’s Video Streaming Plan

Phase 1 = FY 2006 – NOW!

Hybrid product solution – Not fully redundant

$70K Budget

Pilot project to include 3 different components: MPEG4 / Kasenna Optibase / Black Box / Redhat FLV / Flash Media Server / Dell 2850 / W2K3 MPEG4,AAC,MOV / Quicktime Streaming / Apple XServe / OSX10.4


DU’s Video Streaming Plan / update – Cont

Want to “prove” the technology MPEG 4 (Part 2&10–H.264) was the goal

Flashvideo 1MB/sec (FLV Codec, ONVP6 Soon) MPEG4 Part 2 (480x360) MPEG4 Part 10 (having problems) Apple X-Serve not yet implemented

Presently using Darwin on Windows Box for test

Continued Bandwidth target: 300k for off campus (distance) and 1M for on campus


Kassena

1 x Video Storage/Streaming Server Starting with their lower end server as trial “Optibase” Appliance Server “Mediabase 8” Software Linking with External Encoder

Live Events is Target Application VBrick and or Optibase? Not yet implemented / Planning


Macromedia’s Flash Communications Server

Software – on Dell Hardware Stacking 3x Professional Lic.(30Mbps) Allows for “Interactive” response to media

content – custom interfaces/controls Requires Expert (trained) Programming

C.T.L bringing programmers to table @ DU New Version (2.0) coming in October

Comparable to H.264 / MPEG4 / WMV


Apple – XServe Platform

Apple G5 XServer Attached SAN (3.5 Terabytes) Fiber Channel 2 Attached MPEG 4 – Parts 2 & 10 3GPP (1 and 2) streaming for future Users @ DU will be required to download and use

QuickTime Player PC and MAC supported

CTL Piloted Darwin (free) Server on Windows Platform with success (Solaris Compatible)


Asset Catalog Database Server

Dell Hardware / Windows Server 2003 MY-SQL and/or Open LDAP Directory for

media content data Catalog media content data function

Allows for existing campus video projects to be integrated into this project

Video Content Backups

Complete “Disk Copy” vs. Central Tape Solution. DU just upgraded to Scalar LT03 Drives

SAN on Apple offers a portion of this… Not nailed down yet….. Policy ? Both Methods ?


DU Athletics

WCHA Video Exchange Basketball & Hockey Coaches Only Hosted by XOS Used to postal mail video tapes to one

another Download and watch high quality games for

review – 720x480 – MPEG 4 ~1.5 GByte per Hockey game


DU Athletics – Public Video Trial partnership with FOX sports Hosted my MSN.com

Linked from DU Website: http://denverpioneers.collegesports.com/ ->

http://msn.foxsports.com/id/5133174 Data flow is an Akamai cache stream from France !?!

Users do not register/pay for streams MSN/FOX advertisement driven Small % (TBD) back to DU 30 second intro spot must watch

DU Athletics website is run by FOX content competitor, Collegsports.com Just purchased by CBS They also have a streaming offering for $6.95/mo or $50/year

Streaming wars !?!


FOX/MSN Some games are full-length – produced by DU DU specific ads - 5 minute or as a “commercial” FOX retains rights

Some games are highlights only FOX produced Issues: Cutting off announcer, etc. DU training FOX people how to do it

430x240 resolution – not bad on full screen No statistics yet from MSN/FOX – waiting…
