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.
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.
IP, TCP, IPv6. HTTP. HTTP 1.0, HTTP 1.1,
HTTP 2.0, HTTP header fields. HTML 5.
Hands on: Analysing HTTP.
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.

client software. CDN, caching, multiple servers.
Hands on: Analysing CDN and Internet delivery.
