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.

Processing of streamed multimedia data

A method and system for streaming multimedia data over a communication network. Live multimedia content is divided into multiple data chunks. Each generated data chunk: has a first chunk size, is associated with a respective portion of the live multimedia content, and is indexed according to a time associated with the live multimedia content such that each data chunk is associated with a unique time at which each data chunk begins. The data chunks having the first chunk size are stored as the data chunks having the first chunk size are being generated. The stored data chunks having the first chunk size, starting at the one stored data chunk, are converted to data chunks having a second chunk size that differs from the first chunk size. The data chunks having the second chunk size are directly transmitted to a Content Delivery Network (CDN) for subsequent transmission a client device.

Processing of live multimedia content over a communication network

A method and device for streaming multimedia data over a communication network. Data associated with multimedia content is received over the communication network. Portions of the data are processed into multiple data blocks. The multiple data blocks are associated with multiple segments by associating each segment with at least two data blocks of the multiple data blocks. The segments of the multiple segments are sequenced according to a stream index. The stream index is assigned to a main index that describes a set of streams for the multimedia content.

A method and associated device for streaming multimedia data over a communication network. Data associated with live multimedia content is received. Portions of the data are processed into data chunks. Each data chunk is associated with the live multimedia content. A request is received for the live multimedia content. The data chunks associated with the live multimedia content are transmitted over the communication network, in response to the request for the live multimedia content.
