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 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.

Processing of live multimedia content and/or data streams over a communication network

An on-demand multimedia stream processing system receives multimedia streams from broadcasters and processes the streams for viewing on a wide range of client devices. To decrease the use of computing resources, processing jobs are started and stopped based on user demand. When a multimedia stream is received from a broadcaster, the processing system does not start processing the multimedia broadcast stream until a request for a processed stream is received. The processing system automatically terminates processing jobs when the audience of a processed stream drops to zero or some other stop condition is met.
