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

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 ?

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
