Claim 19:
20. Client configured to retrieve from a video streaming server a video concerning a section of a scene, the client comprising a programmed computer or electronic circuit configured to
retrieve from the video streaming server a stream formatted in a file format and comprising
a set of one or more source tracks incorporating slices, the slices in the set of one or more source tracks forming a subset of slices of a video data stream into which pictures of a video are coded each which shows the scene, wherein the pictures are spatially subdivided into tiles and within each picture tiles within the respective picture are coded independent from each other, the subset of slices incorporating the slices into which tiles within the section are encoded; and
a set of one or more gathering tracks comprising construction instructions indicating a synthesis of a section-specific video data stream into which pictures showing the scene's section are encoded;

synthesize the section-specific video data stream according to construction instructions in the set of one or more gathering tracks on the basis of the one or more source tracks, and
subjecting the section-specific video data stream to decoding by a video decoder
wherein the construction instructions form a sequence of copying instructions and the client is configured to, according to the sequence of copying instructions, and one or more insertion instructions,
wherein the client is configured to,
according to the one or more copying instructions, copy certain portions from the slices of the set of one or more source tracks to synthesize the section-specific video data stream, and
according to the one or more insertion instructions, insert a content of an operator field of the one or more insertion instructions to synthesize the section-specific video data stream.
