Agenda
• OTT?
• OTT 4K?
• Can we actually stream 4K Over-The-Top?
• Why the Internet is not built for 4K OTT delivery
• What we can do about it

7. ©2016 AKAMAI | FASTER FORWARDTM
OTT is…Broadcasting of premium audio, video, and
other media over the Internet without the control and/or
ownership of the distribution network.
What is OTT?

8. ©2016 AKAMAI | FASTER FORWARDTM
4K = 15 Mbps
What is the bitrate the major OTT platforms use for 4K?

Grow revenue opportunities with fast, personalized
web experiences and manage complexity from peak
demand, mobile devices and data collection.
TCP will trade speed / throughput for reliability:
• The farther away the server (Round Trip Time)
• When there is congestion / packet loss
TCP based transport (e.g HTTP) is built for
reliability, not speed

Akamai stream acceleration technologies are
designed to get the reliability of TCP, and the
throughput of UDP
• Highest quality video
• Less ABR, broadcast like viewing experience
• Less buffering
• Most importantly longer viewing time
