Abstract
For streaming data in a mobile communication network, a descriptive file of a stream is provided. The descriptive file comprises a list of delivery source identifiers, e.g. URIs, for unicast delivery of data segments of the stream. A broadcast indicator is selectively added to the descriptive file so as to indicate whether broadcast delivery of the data segments is available. Adding the broadcast indicator and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.
