Abstract:
Methods and apparatuses provide real-time or near real-time streaming of content using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method includes providing multiple redundant locations that provide media content to client devices using alternative streams. To implement failover protection, a first server device or first content distribution service creates a stream, or multiple alternate bandwidth streams and generates playlist file(s). A second server device or second content distribution service creates a parallel stream, or set of streams. A client attempts to download the playlist file(s) from a first uniform resource locator (URL) using a first stream associated with the first server device or the first content distribution service. If a client is unable to download the playlist file(s) from the first URL, the client attempts to switch to an alternate stream associated with another URL.
