David W. Fleig, Computing & Information Technology


DefinitionsDefinitions• IPTV

– Extension of cable or satellite system– Requires a carefully conditioned

network• IP Video

– Broader definition• Both

– IP encapsulation and transport– May use multicast or unicast


IPTVIPTV• IPTV is singular, unique• Extension of cable or satellite system

– Traditional programming

• TV’s, flat panels, etc. require set top box• Computers require desktop client (viewer)• Properly and carefully conditioned

network– Especially in a multi-channel, multi-viewer

environment


IP VideoIP Video• Different

– May be a small or large system• % of network or netops utilization

– Different things to different people• Broadcasters, Educators, Research,

Corporate, Government, Defense, Finance, etc.

– Teaching & learning, research, archiving or communications tool

– Webcasting and distance learning special cases– VOD, entertainment

– Coexistence on a LAN• Also requires carefully conditioned network

– May include IPTV

IssuesIssues

• Cost–IP vs. Legacy

• Licensing and rights–Analog…Easy–Digital…Difficult


IssuesIssues• Cost of IPTV ownership

– 40 channels– $5K to $10K per channel / encoder– $200K to $400K– Computer-based

• 5 year replacement cycle• Annual licensing fees

– Network management• Real-time environment• Multicast• Test and measurement

– Network Consumption

EncodersEncoders• Appliance or Computer-based

– MPEG 1, 2, 4, WM• MPEG 2 – 720 x 480• MPEG 4 – 320 x 240

– Native to QT

– WM• MPEG 2 or 4• No Multicast

– H.26x• H.264

– Very convenient and portable• Broadcasting• Proprietary


H.264H.264• Universal player• Better quality, lower bitrates• aka MPEG 4 - Part 10• ISO standard• SD and HD• Excellent for videoconferencing• Very promising


H.264H.264• $30K+ per encoder

– Broadcast quality– Constant frame rate– 30 fps +

• 15+ DSP chips to encode• Evolving• Written for unlimited proc power• Modern, high speed computer to decode• Future

– Video Furnace, Inc.• Custom silicon

– VBrick, Inc.• $8K per encoder• 3 DSP chips

– Others…probably the same


Which way?Which way?• EchoStar (aka DISH Network)

– Value proposal• Provide / Expand Headend – “No

Charge”– Equipment and labor– Analog or QAM– Fiber transport– STB’s– Built to WSU specs

• Tradeout - Multiyear contract– Educational rates– Negotiated ROI


Digital RightsDigital Rights• Will you be classified as a cable

operator?• Will you be fundamentally

different than a cable company?• Concept and intent of the

Franchise Agreement – Private for-profit company vs. public

entity– Public interest test


Digital RightsDigital Rights• IP Encoding

– Programming from somewhere…

– EchoStar• “…Can’t offer permission to IP

encode DISH programming…”


Digital RightsDigital Rights• So you want to build one…• Be careful what you carry and

where you carry it…


CopyrightCopyright• Google buys YouTube• Viacom sues Google for “One Billion Dollars”


TrendsTrends• K-16

– Would like more– Research, training, academic support

• Broadcasters– Transport, switch and distribute– May not coexist well with others

• Telepresence• Digital Cinema

– 2K, 4K– 6 Gbps and up


CameraCamera• Network – attached• HD +• H.264?

TrendsTrends• Test and measurement

– Real time, continuous QoS testing• Tektronix• Rohde & Schwarz• Harris

– Multicast• Verification of on-time delivery• Verification of transport• Verification of quality

– Transport and IP


TrendsTrends• Ultra-HD

– NHK Japan– Television to Telesense– 1 Million frames per second cameras– 7680 x 4320– 32 million pixel imaging devices– 16x more detail– ITU-R BT.1769


The Game of the CenturyThe Game of the Century

• IPTV• Triple Play

– Video, Data, Voice• Recent Headlines

– “Fiber Surges Worldwide”– “100 Megabit Nation”– “One Million Homes Connected”– “Slingbox - Consumers want technology that can

turn a computer into a TV”– “Cable Giant Comcast Tries to Channel Web TV”– “AT&T, Verizon Deploy Broadband Fiber Locally”– “Subscription TV Providers Think Out of the (Set-

Top) Box”

What weWhat we’’re doingre doing• Wait on “locally-encoded” IPTV• Limited

– OSTN• Student Channel

– U of M IP HDTV MiLR Project– HDTV Videoconferencing– Legacy CATV system

• IP-based tools• Drivers

– Unique, specific applications• Foreign language, Medicine

• More IP Video than IPTV
