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 a plurality of streaming requests, including mode requests (P11a, P11b), from a plurality of user devices (11a, 11b), the apparatus comprising a memory unit (7) adapted to store media data in the form of a plurality of payload data sets (9a, 9b), a state device (506) adapted to set a mode in accordance with each one of the mode requests (P11a, P11b), and a streaming unit (3) adapted to stream the payload data sets (9a, 9b) in accordance with the set modes. The streaming unit (3) is adapted to receive from the memory unit (7) a plurality of control data sub-sets (101a), each comprising at least two edit portions (1X, FF1, FF2... ), each comprising data corresponding to an address in the memory unit (7).
