Internet video is experiencing a dramatic growth in both fixed and mobile environments. All available data points indicate that internet video is likely to be the long-awaited killer application for mobile data networks. It will also create significant business opportunities for the fixed internet access providers. Internet video is currently dominated by a handful of proprietary technologies that exploit and reuse existing Web infrastructure to deliver internet video. To address these market demands, the Motion Picture Experts Group (MPEG), in coordination with the Third Generation Partnership Project, has taken the lead to define an enabler standard for streaming video and multimedia delivery over the internet. MPEG Dynamic Adaptive Streaming over HTTP (DASH) specifies a delivery format that enables interoperability among servers and clients from various vendors. DASH clients can select and dynamically switch representations to provide a seamless user experience. The standard evolves proprietary HyperText Transfer Protocol (HTTP) streaming solutions to provide a universal format for internet video delivery by reusing, building on, and interfacing with a significant number of existing state-of-the-art technologies.
