The latest MPEG standards provide enhanced mechanisms for encoding and delivery of Over-The-Top Dynamic Adaptive  Streaming over HTTP. MPEG-DASH offers a new standard way to build manifest files for adaptive bit rate delivery. The design of new services depends upon understanding the new commercial and technical features.  It provides for insertion of targeted advertising as well as the ability to deliver video quality that can adapt to a range of devices, networks and platforms.

This course will examine Over The Top delivery of WebTV demonstrating its differences from traditional broadcast TV and Multicast streamed IPTV. It will describe the key engineering problems in building WebTV services and using hands-on demonstration exercises allow attendees to experience the impact of differing levels of delay variation and packet loss using Internet simulators. It will then provide a comprehensive understanding of MPEG-DASH comparing it with Apple HLS, Adobe HDS and Microsoft Smooth Streaming. Hands-on exercises configuring MPEG-DASH services and comparing its performance with identical video delivered through other streaming technologies will allow attendees to have a sound understanding of the new technology. They will analyze the protocols used for delivery using WireShark providing attendees with the skills to use key analysis software used to troubleshoot application platforms and the network technologies used within a range of new Adaptive WebTV systems

Objectives

 When you have completed this course you will be able to:

  • Describe key features of Over The Top WebTV services
  • Analyze manifest files used in adaptive bitrate systems
  • Understand how MPEG-DASH has standardised services
  • Build a working MPEG-DASH service
  • Calculate the network performance demands for MPEG-DASH services
  • Compare MPEG-DASH with HLS, HDS and Smooth Streaming
  • Identify Content protection issues and select AES profiles for deployment
  • Appreciate the use of MPEG-DASH Media Program Descriptions (MPD)

Target Audience

Who should attend this course:

This course is intended for engineers, service designers, developers and systems engineers involved in the development of WebTV products and services.  Hands-on exercises will use Windows-7 based PCs or laptops connected to in-class Internet Simulators to test performance under controlled fault conditions. Next exercises will be run over in class LANs to test optimal conditions and then finally out over the open Internet to demonstrate real life operation. Attendees will be given an opportunity to connect their own iPAD, Android and iPhone devices to the in-class WiFi service to experience the services that they build on real devices.
