Abstract

An apparatus and a method for data streaming, as well as a combination, of an apparatus (1) for data streaming and a plurality of user devices, are presented. The apparatus is adapted to receive media data in the form of a plurality of payload data sets (9a, 9b) from at least one data source (8) and a plurality of streaming requests from a plurality of user devices (1 1a, 1 Ib), the apparatus comprising a memory unit (7) adapted to store the payload data sets (9a. 9b), and a streaming unit (3) adapted to stream the payload data sets (9a, 9b) according to the streaming requests, the streaming unit (3) is adapted to receive a first sub-set (91a, 91b) of a payload data set (9a, 9b) from the memory unit. The streaming unit (3) is adapted to receive from the memory unit (7) a first sub-set (10 Ia. 101b) of a control data set, which first control data sub-set (101a, 101b) comprises data corresponding to a location in the memory unit (7) of a second sub-set (92a, 92b) of the payload data set (9a, 9b).
