  • Demystifying Video Delivery Protocols (July)

Thursday, July 16, 2020 at 10:00am (PT)

When streaming hit center stage, it was dominated by RTMP and RTSP. But these were proprietary protocols, requiring dedicated servers and infrastructure. Then came chunked HTTP delivery which radically changed the game, enabling delivery to leverage established HTTP servers and technologies long used to serve web pages. Fast-forward to today and you have a bevy of streaming protocols available, from traditional technologies like RTMP and RTSP, to HTTP Adaptive protocols like HLS, MPEG-DASH, and CMAF, and newer entrants like SRT, WOWZ, and WebRTC. In this webinar, we’ll explore the pros and cons of the different streaming protocols for different use cases as well as looking at best practices for implementation including configuration tuning and other optimization that make the protocols operate at peak performance. Panelists for this exciting webinar included: – Ali C. Begen (Comcast) – Maxim Sharabayko (Haivision & SRT Alliance) – Kieran Kunhya (Open Broadcast Systems & RIST Forum) – Josh Pressnell (Penthera) – Barry Owen (Wowza) This panel was moderated by Jason Thibeault, Executive Director of the Streaming Video Alliance.

Topics Covered

  1. How do we classify protocols? Are there different protocols for ingest? For delivery? Specifically for streaming? What influences a streaming provider to choose one over another?
  2. What is the state of SRT today? Are we seeing a lot of adoption? Commercial deployments? What are the use cases it primarily addresses?
  3. RIST has recently come to the streaming world. What was the reason behind its development and how is it faring?
  4. WebRTC, as a delivery protocol, has seen a lot of interest, especially for ultra low-latency use cases (like gambling and sports). What are the primary differences between it and LL-HLS or LL-DASH?
  5. Are there performance or architectural considerations for choosing which live streaming protocol to use?
  6. What are the primary differences between today’s live streaming protocols (DASH, HLS, Smooth) and those before (RTMP and RTSP)?
  7. What are some of the decisions a streaming provider should make when selecting a low-latency protocol?
  8. Is the fragmentation of streaming protocols causing confusion for streaming platform operators, especially as streaming picks up stream as a viable replacement for traditional broadcast?
  9. How does scale impact the selection of a streaming protocol?
  10. What are the impacts of live streaming protocol choice on other parts of the streaming tech stack?
  11. What’s on the horizon for the current set of protocols? Are there new approaches and technologies being tested as well? Will we see another protocol in the next year? Two years?
