Tutorial (second part)
Summary
This tutorial consists of two main parts. In the first part, we provide a detailed overview of IPTV and its building blocks, explain the architectures and protocols used to carry video over IP in core, aggregation, access and home networks. We discuss the experiences from the existing deployments, and present the relevant standards and current challenges.
In the second part, we survey well-established streaming solutions for over-the-top (OTT) video delivery, explaining how OTT video delivery contrasts to traditional broadcast and managed IPTV services. We then describe existing and emerging service models reliant upon Internet video, including HTTP adaptive streaming along with all the workflows for content generation, distribution and consumption. Throughout this part, we review recent research findings and discuss future directions. Emerging standards and industry practices will be covered as well.
Upon attending this tutorial, the participants will have an understanding of the following:
- Fundamental differences between IPTV and IP video
- Video transport, protocols and standards for IPTV
- Features of various types of streaming protocols
- Principles of HTTP adaptive streaming
- Content generation, distribution and consumption workflows
- Standards and emerging technologies in IP video space
- Current and future research on managed and unmanaged video delivery
Motivation
Video over IP is a reality to all of us and its growth pace is unprecedented. This is an area that cannot be ignored by anybody who is working in the networking field. Unlike most of its counterparts that offer mostly theoretic content, this tutorial will focus on practical matters such as existing products and solutions that are being used by millions of users around the globe and the new developing technologies that will be used by the same users in a few years.
Topics Covered
- Part I: Managed Video
- IPTV architecture, protocols and SLAs
- Video transport in the core networks
- Video distribution in the access networks
- Improving viewer quality of experience
- Today's challenges
- Part II: Unmanaged Video
- Survey of well-established streaming solutions for OTT video delivery
- Architectural differences between OTT video, traditional broadcast and IPTV
- Multi-bitrate encoding and encapsulation workflows
- Example deployments including TV Everywhere
- Scaling and improving streaming, multi-screen/hybrid delivery
- Recent research findings and future directions
- Standards and industry practices
Tutorial Type
The tutorial will be in the form of a lecture. However, live demonstrations are planned to show specific examples.
Expected Audience and Prerequisites
This tutorial includes both introductory and advanced level information. The audience is expected of understanding of basic video coding and IP networking principles. Researchers, developers, content and service providers are all welcome.
