Video Breakthroughs

The Hippo Media Server is a simple, standalone HTTP server designed to simplify the delivery of MPEG DASH and Smooth Streaming media. MPEG DASH and Smooth Streaming are both protocols for HTTP-based adaptive streaming. With adaptive Streaming, a media presentation is served to streaming clients as a sequence of small media segments (each segment containing typically 2 to 10 seconds of audio or video). Each segment is accessed over HTTP with an individual URL. In order to serve an adaptive streaming presentation with a regular HTTP server like Apache, Nginx or other populare HTTP servers, one needs to split the original media files into small individual files, one for each segment, so that they can be accessed through separate URLs. This can be very difficult to manage. The Hippo Media Server implements a simple URL virtualization scheme: instead of mapping each URL to a file in the server's filesystem, each URL consists of a pattern, which is parsed by the server when it handles a request, and from which it can locate the appropriate portion of a file in the filesystem. This way, a single media file containing the media data for the segments can be represented as discrete URLs.
