The present document specifies the File Format used to store and playback DVB services. The audio/video properties of the services that may be contained in this format are defined by specifications TS 101 154 [3] for MPEG-2 Systems services@ and TS 102 005 [4] for RTP carried elementary stream services. The present document also specifies the storage of a range of additional data relevant to the services. This includes: ? specification TS 102 825 [14] when used to protect MPEG-2 Systems services; ? TV-Anytime Related metadata@ as defined by TS 102 471 [7]@ TS 102 323 [5] and TS 102 539 [10]; ? any data that is carried with a transport stream as part of the service; and ? 3GPP Timed Text [16]. Through the defined brands@ the present document provides definitions of what may be contained in the file. However@ the specification does not preclude any extensions from also being present@ provided they do not conflict with the requirements of the present document. The present document does not require that the File Format be used internally by a device@ and as such the specification can be viewed as an interoperability point. The use of the File Format is outside the scope of the present document.
