Abstract

A method of delivering a live stream includes recording the stream using a recording tier, and playing the stream using a player tier. The step of recording the stream includes sub-steps that begin when the stream is received in a source format. The stream is then converted into an intermediate format (IF), which is an internal format for delivering the stream within an overlay network. The player process begins when a requesting client is associated with a network proxy. In response to receipt at the proxy of a request for the stream or a portion thereof, the proxy retrieves (either from the archive or the data store) a stream manifest and at least one fragment index. Using the fragment index, the intermediate format file fragments are retrieved to the proxy, converted to a target format, and then served in response to the client request.
