HTTP 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.
