This course covers OTT TV by primarily looking at the
delivery of video streams using HTTP adaptive
streaming. Both MPEG DASH and HLS are
investigated. Hands on sessions involve using
Wireshark to analyse streams as well as crafting
segmented content.
What will you learn
Explain what OTT TV is, and how it works.
Describe the OTT TV architecture.
Use Wireshark to analyse and troubleshoot OTT
video streams.
Explain how HTTP adaptive streaming works.
Evaluate and compare MPEG DASH and HLS.
Use tools to create OTT TV adaptive streams.
OTT TV for engineers course details

What is OTT TV?
Brodeo providers vs ISPs. Progressive downloads
versus streaming. Why not UDP and RTP for
delivery? Adaptive bit rate streaming. Standards.
Hands on: Base network setup. Using WireShark
for HTTP streams.
HTTP protocol stack
IP, TCP, IPv6. HTTP. HTTP 1.0, HTTP 1.1,
HTTP 2.0, HTTP header fields. HTML 5.
Hands on: Analysing HTTP.
Adaptive bitrate streaming principles
Chunks, fragments, segments. Manifest files.
Encoding, resolution, bitrates. Addressing,
relative and absolute URLs, redirection. When
does the client switch streams? Switch points.
Hands on: Walk through of client behaviours on
a stream.
OTT TV streaming architecture
Server components, distribution components,
client software. CDN, caching, multiple servers.
Hands on: Analysing CDN and Internet delivery.
TCP and HTTP streaming interactions
TCP ACK, TCP connections, unicast only. TCP
flow control, TCP and performance.
Hands on: TCP window sizes.
MPEG DASH
Stakeholders, DASH architecture and model,
codec agnostic, XML, Media Presentation
Description, Media Presentation, segment
formats.
Hands on: MPEG DASH analysis.
HTTP Live Streaming and others
Stakeholders. Media segments, media playlists,
master playlists. Adobe HTTP dynamic
streaming, Microsoft smooth streaming.
Hands on: Analysing HLS.
Tools

developer tools for HLS.
Hands on: Creating segmented content.
Security
HTTPS, encryption, content protection.
Hands on: Encryption analysis.
Summary
Choosing a streaming method. Impact of live
versus VoD. Web sockets.
