HTTP streaming training course description
This course looks at the delivery of video streams using
HTTP adaptive streaming. Both MPEG DASH and HLS
are investigated. Hands on sessions primarily involve
using Wireshark to analyse streams.
What will you learn
Use Wireshark to analyse and troubleshoot
HTTP video streams.
Explain HTTP adaptive streaming works.
Evaluate and compare MPEG DASH and HLS.
Use tools to create HTTP adaptive streams.
HTTP streaming training course details
Who will benefit:
Anyone working in the broadcast industry.
Prerequisites:
TCP/IP foundation for engineers
Duration
2 days
HTTP streaming training course contents
What is HTTP streaming?
The old way. 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.
HTTP 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.

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.
