The Recording Industry Association of America calculates that revenues from services including Spotify, Pandora and YouTube went from 3 per cent of industry revenues in 2007 to 15 per cent, or more than $1bn, in 2012. … What is lost from many calculations is the fact that the urge to own may be weaker in the age of streaming, but so is the urge to steal. Traffic to peer-to-peer file-sharing and torrent sites is declining where legal alternatives are offered. Netflix’s Ted Sarandos said in May: 'When we launch in a territory, the BitTorrent traffic drops as the Netflix traffic grows.'

• MPEG-DASH at the BBC:The media is encoded a number of times at different bitrates. Each encoding is called a Representation. These are split into a number of Media Segments. The client plays a programme by requesting segments, in order, from a representation over HTTP. Representations can be grouped into Adaptation Sets of representations containing equivalent content. If the client wishes to change bitrate it can pick an alternative from the current adaption set and start requesting segments from that representation. Content is encoded in such a way to make this switching easy for the client to do. In addition to a number of media segments, a representation generally also has an Initialisation Segment. This can be thought of as a header, containing information about the encoding, frame sizes, etc. A client needs to obtain this for a given representation before consuming media segments from that representation.
Finally, there is also a Media Presentation Description (MPD), commonly referred to as the manifest. This documents the Adaptation Sets and Representations, together with durations and URLs.
