Over the Top/Under the Hood OTT Video over IP

Mayumi Hirtzel, University of Pennsylvania AHECTA 2011 June 23, 2011 - Tampa, FL

2 Overview

Overview

Introduction Questions? Perspectives? (A little) Background about Penn and PVN Why we chose an OTT solution So, what is “OTT”? “And what makes you qualified to talk about it?” OTT Examples (Hardware and Interface) Specifics of each option Quality Comparison Findings at Penn

3 Video over IP

Video over IP

How many of you offer video over IP (streaming, on-demand capacity) on your campus broadband Ethernet network? How many of you have a broadband Ethernet network?

4 How, When, With What

How, When, With What

Even if you don’t have “on-demand, video over IP” as a service, students are using your network to watch TV, movies, and more: How they want to watch it When they want to watch it With the device of their choosing

5 PennNet and PVN

PennNet and PVN

PennNet: Penn Internet access Wired Ethernet 10Mbs to wallplate (throttled) Wireless issues Penn Video Network HFC distribution network on campus (ca 1994) ~8000 drops / ~60 channels / 550MHz Yes to Digital and some HD (QAM)

6 Why OTT at Penn

Why OTT at Penn

Past “failures” Inuk/Internet 2 project No clear winner in IP Video for us After 2 years… Why duplicate existing service? Cable TV already successful Supplemental lineup more appealing “Who wants it?”

7 Over the Top

Over the Top

(In this case) Set-top box designed for media display using an Internet network input for data/packet retrieval Three examples: AppleTV (Apple) Boxee Box (D-Link) Roku HD (Roku)

8 Long Walks and Cute Animals

Long Walks and Cute Animals

Not an engineer! TV-watching habits I like TV! (But not so much “live”) Media saturation from multiple sources Laptop, smartphone, game systems, TV (sort of) Opinionated. Cheap. Impatient. Me ~ Average student viewer?

11 Boxee Box

Boxee Box

Odd design / Big Keyboard remote HDMI out (cable provided); Optical out 1080p and 1080i Many, many apps / channels Favor “freebies” like YouTube, TED, Khan Academy Essentially designed to replace PC running Boxee software

15 Did You Just Waste My Time

Did You Just Waste My Time

All OTTs specializing in digital media reception and streaming do essentially the same thing AppleTV, Boxee, Chumby, GoogleTV, Orb, PS3, Roku, Wii, XBOX 360 … ! Which one best matches your - or your students’ - needs and wants?

16 Penn Findings

Penn Findings

No noticeable blips on network No control group or testing Needed to educate students about registration Not exactly as easy as “plug-and-play” Same as any other Internet device Largest percentage of registered “peripheral” Internet devices (not computers) was XBOX 360 @ 30%

17 All About the Benjamins

All About the Benjamins

…and the Benitas! Students want what they want: What’s in the box, not the box itself! Students don’t think, “I want to watch Showtime tonight!” They think, “I want to watch ‘Dexter’ tonight!”

18 K.I.S.S

K.I.S.S

Penn opted for a solution that was extremely low-cost - for us, and for them - with OTT recommendations Mom and Dad already have Comcast, Time Warner, FiOS, Dish, DirecTV at home - many are also available to students (remotely) Education issue HBO Go very successful example Talk to your vendors about on-demand options

19 What is the Answer

What is the Answer

IP Video is the future … … But how far away? Over IP? In “The Cloud?” Existing OTT services are a stop-gap solution No clear “winner” in the race of which service is best If you want to take a cautious approach to Video over IP, OTT is one way to do it.
