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


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?


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 speedCHALLENGE:

How does latency and packet loss impact throughput?


Grow revenue opportunities with fast, personalized web experiences and manage complexity from peak demand, mobile devices and data collection.How do we overcome the challenges?



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
