Claim Text:
1. An apparatus, wherein the apparatus is configured to process stored transport data packets in a media data container, the stored transport data packets comprising a media payload of packetized media access units and control information for recovering accurate media timing of the media access units, and to process stored associated meta information in a metadata container, the associated meta information comprising transport timing information and location information indicating a storage location of the stored transport data packets in the media data container, and the apparatus comprises: a processor arranged to determine, based on the control information provided in the stored transport data packets and the transport timing information, decoding-time-to-sample information for each media access unit, wherein the decoding-time-to-sample information reflects the media timing and indicates at which time instant to replay which payload of the stored transport data packets, and to also determine, based on a content of the stored transport data packets and the stored associated meta information, decoding information samples on a media access unit basis, such that each decoding information sample is related to a media access unit and comprises links to one or more transport data packets relevant for de-packetizing the media access unit from the stored transport data packets, wherein the processor is adapted to determine the decoding information sample, such that it indicates a start-address and an end-address of the related media access unit within the stored transport data packets, wherein the start-address denotes a location of a media data sample indicating a beginning of the media access unit and wherein the end-address denotes a location of a media data sample indicating an end of the media access unit, and wherein the processor is adapted to store, in the media data container, the decoding information sample, and to store associated decoding-time-to-sample information as decoding meta information in the metadata container, the decoding meta information indicating a decoding time and a location for the associated decoding information sample in the media data container, and the stored transport data packets comprise MPEG-2 transport stream packets or RTP packets comprising packetized media data samples.
