Agenda
Let’s try ingest acceleration using one’s Mac facetime camera,
ffmpeg as your encoder, deliver the stream via Akamai MSL 4.1 and
play back on your Apple TV
 Challenges with OTT Live Broadcast
 MSL 4.x:
 Key Differentiators
 Demo: ingest from your Facetime camera and
watch it on Apple TV

●Challenges with OTT Live Broadcast
CHALLENGE
1. Having Consistent Contribution of high
quality 24/7 live/linear streams in
DASH/HLS/HDS formats, for multiple devices.
2. Achieving Broadcast Reliability Online
ensuring that the content is always available
3. Minimizing latency between broadcast and
live streams to less than 10 seconds
4. Quickly Identifying and Reacting to
Ingested Stream Health to address issues in
near real-time

●MSL 4.X: What is it?
Composed of the new ingest and mid-tier functionality, MSL 4 is Akamai’s liveOriginTM solution
which is specifically designed to bring the experience of broadcast TV online.
10 second latency
Transforming the internet into 21st century’s TV antenna.

The Solution
Live Content
Customer’s encoder
disconnects from
problematic EP
Attempts reconnect,
and gets mapped to
available EP
Encoder recovery is
automated with no
disruption to viewers
Ingestion Server
Purpose built ingestion server with a
dynamic, automated mapping system
for routing the encoders to the most
appropriate entry point when an
encoder initially connects and
throughout a live broadcast

The Solution
Key Differentiator: Low Latency
Traditional Latency 30 Seconds
+ behind broadcast
 Most applicable to Broadcasters, Sports
providers who also broadcast content on TV
 Standard feature of MSL 4.0
 Leverages standard web technology like
HLS and DASH
 Does not require player changes
Low Latency 10 Seconds
(1-2 behind broadcast)

The Solution
Key Differentiator: Enhanced Monitoring & Alerting
5 Sample Measured Metrics
1. Bitrate
2. Latency
3. Total # of Streams
4. Packet Loss
5. Error Rates
Includes near real-time alerting
