• Content (video) delivered via the Internet that is commonly packaged for subscription by SP.

Typically „Free‟ (ad insertion) or subscription (e.g., Netflix rental)

• OTT Sites hosted by Content Providers and Aggregate Service Providers (e.g.,Huste.tv, hulu)

• Launched 25th December 2007

1 million+ programs streamed each day

>75TB/day current average

180TB Peak during Beijing Olympics

• Currently 15%of entire UK Internet traffic

Peaked at 20% of UK Internet Traffic during Olympics

• ISP Costs +200% since iPlayer Launch

Increase from 6.1p to 18.3p per user

ISP business models broken

• But what would happen if it was available on your Television?

Consider 20x capacity growth…..

7 Day Catch-Up via your computer

Free of Charge (as long as you are in the UK)

Available on multiple platforms

iPhone and iPod Touch via WiFi

Nintendo Wii, PS3

Mobile phones incl Nokia N95

BBC iPlayer


• Viewing time remains relatively constant at ~32 hrs per week. All sources – OTT & TV.

• Internet Video(IV) consumption annual growth rate ~52%

• IV growth peaks 2015 (60%) and declines thereafter to 20% (~2020)

Hard to predict, but here‟s a current theory…

Convergence

~2019 ?


Example SP CDN Applications


• Driven by UK Internet Video traffic and BBC iPlayer

• BT enters into Wholesale marketplace to become the “white label” platform for next generation video services

• Plans to expand services “off net” to LLU, Cable and Mobile operators

• Monetises iPlayer market transition

Video Delivery Protocols


Most of today‟s technologies were developed for real time streaming and file transfer applications.

• MPEG-2 Transport Stream

• RTP and helpersprotocols RTCP / RTSP (run on UDP/TCP port 554)

• HTTP (run on TCP port 80)

Used for progressive download, adaptive bit rate - veryuseful to pass by the firewall.

• RTMP (run on TCP port 1935)

Streaming Protocol from Adobe (also RTMPE (Encrypted), RTMPT (Tunneling) RTMP embedded in HTTP, RTMPS # RTMP embedded in HTTPS)


• NOT a network transport protocol

• Mechanism for packetizing and multiplexing encoded audio/video data.

Serialized Constant Bit Rate (CBR) data stream

Originally designed for circuit-based ATM networks and Real-Time Data Transport

• Facilitates flexible Content Processing

Headends: Encoding, Multiplexing, Transrating

Regional: Program Add/Drop, Ad-Insertion

Edge: Ad-Insertion, HFC Carriage (QAM)

• Transport for Cable STBs worldwide. Basis for „Digital Cable‟.

• Circa mid-2000‟s – SPs began to encapsulate MP2TS into IP packets for WAN transport. Ongoing today.

Live/Linear - Multicast

Video On Demand - Streaming

MPEG-2 Transport Streams (MP2TS)


• Stateful Streaming for „Continuous Media‟ with an intrinsic timeline.

• Real-Time Transport Protocol (RTP) is Internet standardized for real-time data/media transport (video, audio). IETF RFC-3550.

• Commonly used for Video/Tele Conferencing solutions (Re: ITU H.323 Standard)

• Very lightweight (min overhead) and designed to be carried on other transport protocols (e.g.,UDP, TCP).

• RTP is typically accompanied by „helper‟ protocols

RTP – media + timestamp + sequence counter

RTCP – „control‟. Carries QoSfeedbk from Rcvr to Sender. Synch support for different media streams.

RTSP - Session set-up and Control

• RTP/RTCP/RTSP implementation varies by application.

• RTP often disallowed by routers/NAT/firewalls

Traditional Streaming – RTP + RTCP + RTSP


• Prevalent form of Web-based media delivery for Video Share Sites.

• „Ordinary‟ File Download from HTTP Web Server (E.g., Apache, Microsoft IIS)

• „Progressive‟ = Playback begins while download is in progress

Byte Range Request Supported HTTP 1.1+

File Download Completes

• Unlike streaming, data flows until download is complete. (E.g., pause viewing and download completes in background).

Sometimes leads to inefficient use of bandwidth resources.

• - Downside – Real-time viewing often suffers from poor quality unless network/bandwidth conditions are sufficient.

• + Upside - media file is resident in browser cache. Subsequent playout is smooth.

Progressive Download – Behavior

…. Buffering….…. Buffering….


Adaptive Bit Rate TechnologiesAdaptive Rate Characteristic Elements


• What is it?

Quality video service on common Web Browsers. Uses IP HTTP protocol (port 80).

Adaptive to „shift‟ between video profiles on the fly. Profiles support different resolutions/devices and different bitrates.

Clients are „smart‟ and coupled to servers, (e.g., Msoft SmoothHD, Adobe Zeri, Apple QTX).

• Why is it important?

Facilitates „any device, anywhere, anytime‟ paradigm. Major step towards mobility.

Internet based. Open development and rapid deployment. Engineered for Internet and its CDNs.

Changing legacy SP service model. New business, services, revenue opportunities.


Provider Challenges & Considerations Addressed by AR

Diverse Networks

– Dynamic Internet Conditions

– DSL vs. Cable vs. FTTH

– Network Contention (Mobile/Wireless, Home)

Any Device Capabilities/Resources

– Processing Capabilities

– Display Resolutions

– Multi-tasking

Improved Quality of User Experience

– Faster Start Time, Quicker Buffer Fills

– Minimizing Buffer under-runs: Skips, Stalls, Stutters

Need Internet Video Offering

– Answer OTT threat with N-Screen offerings

– Add „off-net‟ (unmanaged) capability

Infrastructure Re-Use & Evolution

– Leverage Same technology for both Managed/Unmanaged

– CDN Expansion – leverage public CDN + build out

– Content channel, Content Mgt: (xcode, protection,…)

– Path to convergence architecture

Need Is The Mother of Invention


Adaptive Rate Characteristic ElementsStateless Session Operation

• STATELESS Session = „Don‟t Care‟ Server

Client requests and server responds without regard for session state. Each HTTP request processed independently

Traditional Streaming – Server maintains state for length of session. E.g. RTP/RTCP/RTSP.

• „Inverted‟ Client-Server Streaming Model

Client „Pull/Get‟ what it needs

Client manages session state locally and issues requests

• Client can maintain Multiple, Simultaneous, Independent Sessions. Facilitating advanced features, e.g.:

Multiple TCP connections – parallel gets. Re: Move Networks.

HTTP Get „What I Say‟

HTTP Ack „What I Say‟

Client ServerGet what I

• „Intelligence‟ and Control Moves from Server to Client

• Client is media/content aware.

• Client is device and performance aware.

Adapts visual play-out for quality. Staging.

Monitors device performance. CPU spike.

• Client is Network Aware

Tests and monitors packet delivery performance.

• Adapts to Performance fluctuations
