The demands of video editing in terms of the volumes of data involved means the proximity of the footage (being edited) to that of the NLE system doing the editing is governed partly by the capacity of the data connection between the two. The increasing availability of broadband internet combined with the use of lower resolution copies of original material (video proxies) provided an opportunity to not just review and edit material remotely but also (since it is a public network) open up access to far more people to the same content at the same time. In 2004 the first cloud-based video editor, known as Blackbird and based on technology invented by Stephen Streater, was demonstrated at IBC and recognised by the RTS the following year.
