Watching Video over the Web: Part 2: Applications, Standardization, and Open Issues

Many video streaming applications and services exist on the Internet, and we covered several of them in part 1 of this article.1 The most important applications argu ably fall into the mobile and home entertainment categories, which span the range of video presentation formats for portable (PD), standard (SD), and high-definition (HD) video, and these applications include both walled-garden and Internet applications. They also operate on diverse networks, and use both managed and unmanaged end-to-end network services. Here, we identify mobile and home-streaming use cases, and consider the suitability of pull-based versus push-based adaptive streaming for each use case.
