Abstract
A method and system for streaming multimedia data over a communication network. Each segment of multiple segments is associated with at least two data blocks of multiple data blocks. The segments are sequenced according to a unique stream index for one stream associated with multimedia content. The unique stream index for the one stream is assigned a main index that describes multiple streams for the multimedia content. The multiple streams include the one stream. A request for content of the multimedia content is received. The request specifies a data chunk, of the multiple data chunks, that denotes the requested content. The main index is analyzed with respect to the specified data chunk to determine the stream and segments and/or data blocks therein that encompass the requested content. The determined stream and segments and/or data blocks therein are transmitted over the communication network in response to the request.
