A method and an associated SDCDN device for delivering data content in a communication network. A software defined content delivery network (SDCDN) monitors one or more performance indicators regarding an exchange of the data content between a first content delivery network (CDN) and at least one client device using a communication channel, The SDCDN determines that at least one performance indicator of the one or more performance indicators exceeds a threshold performance value. The SDCDN identifies a different CDN in operative communication with the at least one client device. The different CDN includes the data content. In response to determining that at least one performance indicatorexceeds the threshold performance value, the SDCDN transmits a transfer command to the at least one client device to cause the at least one client device to switch to the different CDN and receive the data content from the different CDN.

Software defined content delivery network for flexible, real-time management of large-scale data transfers

A bidirectional connection between a multimedia stream distribution system and a user is used to communicate operational data to and from the user. The bidirectional connection is separate from a multimedia connection that transfers a multimedia stream from the multimedia stream distribution system to the user. Providing a bidirectional connection separate from the multimedia connection is advantageous, among other reasons, because the operational data can be collected effectively at the multimedia stream distribution system independent of any limitations in the multimedia connection. To organize users and reduce processing load, the multimedia stream distribution system assigns users to user groups based on shared characteristics. Groups may be used to propagate information to the users as well as analyze information collected from the users in an efficient manner.

Bidirectional communication on live multimedia broadcasts

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.

On-demand selection of transcoding formats for multimedia broadcast streams

In accordance with one embodiment of the present invention, multimedia content may be streamed, together with associated timing information, to various users, who may provide feedback data in response to the multimedia content; the feedback data may be related to the multimedia content using the associated timing information, and then stored to some medium.
