Abstract

In recent years, audio-visual distribution over Internet has witnessed the growing usage of HTTP based delivery systems. While these systems have their drawbacks for some use-cases, they also have many advantages, the most important one being reusing the existing delivery infrastructure such as HTTP servers, proxies and caches. The MPEG group has started the standardization of the Dynamic Adaptive Streaming over HTTP (DASH) of major transport formats, MPEG-2 TS and ISO Base Media File, and mostly focuses on audio, video and subtitle formats. We believe Rich Media services have a role to play in this landscape, as a presentation layer for the audio-visual content first, but also as a dedicated media in the DASH content for real-time media-synchronized interactive services. In this paper, we present a study on usages of DASH for Rich Media Services.
