OTT Challenges

Audience

2015 : 3 Billions people online

2020 : 5 Billions

Content

4K streaming by Netflix (11 to 16 Mbps)

Habits

Streaming hours viewed > DVDs and Blu-Ray hours viewed (USA 2012)(1)

TV like experience

Connectivity

Average Peak BW is 18.9 Mbps (Q2 2013)(2)

5,7 connected device / home in 2014 (USA)(3)

CDN / Existing Model

Existing Model:

Unicast

Cache

Akamai

> 140 000 servers

> 1200 Networks/ISP

Peak Traffic > 21 Tbps (≈ 9 Millions HD streams 720P/H264/2,5Mbps)

Tomorrow?

2,5 B users * 10 Mbps = 25 Pbps = 25 000 Tbps ( X 1 000 !)

CDN OTT / Requirements

Future proof but also non disruptive:

Works with existing ingest, DRM, targeting & authentication

Uses existing player technology

ABR and advanced features like DVR

Format agnostic: HLS, HDS, Smooth and DASH

MULTICAST

Vast majority of OTT traffic today is unicast,

Multicast is typically enabled within a

network.

Usage:

Live events

(sports, news, prime time)

VOD Exclusivity Launch?

Approach:

Specific telco agreement

Platform software upgrade

Multicast Delivery

HTTP/UDP protocol

Intelligent Pre-

positioning

Peer Assisted Delivery

INTELLIGENT PRE-POSITIONING

Demo with Qualcomm #CES2014 : Smart Gateway

Ability to define policies to proactively push content in a local cache

Usage:

Subscribed video channel

Hot tail / Popular content

Approach:

Gateways, but also game consoles, set-top-boxes, Blu-ray players,

connected TVs …

Spreading content ?

Multicast Delivery

Intelligent Pre-

positioning

Peer Assisted Delivery

PEER ASSISTED DELIVERY

Get video from your peers instead of a server

Efficient architecture for live and popular VOD content

Usage:

Todays adaptive segmented formats (HLS, HDS, Smooth, DASH) lend

themselves nice to peer assisted delivery

Approach:

Large Experience with NetSession

Software embedded into the devices

“Turn consumer electronics into video nodes”(5)

WebRTC opens up the ability for installation-free p2p solutions

Multicast Delivery

Intelligent Pre-

positioning

Peer Assisted Delivery

HTTP/UDP protocol

HTTP / UDP Protocol

This new protocol prevents packet loss and latency by

using(6):

Hybrid HTTP/UDP Transport Protocol

Forward Error Correction

Advanced Congestion Control

Approach:

• Platform integration

• SDK : Android, iOS, Web

Initial Results

• ½ the startup time

• 2x – 5x the bit rate

• 10x fewer rebuffers

CDN OTT / Conclusion & Challenges

Next generation platform will be a combination of :

1. “Larger” footprint

2. Technical Delivery Diversity

Challenges are :

ISPs agreement and business model

Technologies combination

Transparency for users
