Definitive OTT TV for engineers   |    A 2 day   hands on   training course

OTT TV for engineers course description

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.
