Scene section and region of interest handling in video streaming

Client configured to retrieve from a video streaming server a video concerning a section of a scene, the client 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 each slice of the video data stream has encoded thereinto no more than one tile, the subset of slices incorporating the slices into which tiles within the section being a set of one or more tiles wide are encoded;
• and
• a set of one or more gathering tracks comprising construction instructions indicating a synthesis of a section-position-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 by
• replacing first portions of the slices incorporated into the one or more source tracks by replacements signaled by the construction instructions, and/or
• copying second portions of the slices incorporated into the one or more source tracks,
• subjecting the section-position-specific video data stream to decoding by a video decoder.

Video data conceptualized for streaming a spatially variable section of a scene to a client, the video data being formatted in a file format and comprising

• a set of one or more source tracks, each source track being associated with a respective one of tiles into which pictures of a video which capture the scene entirely are spatially subdivided, wherein the source tracks have distributed thereinto slices of a video data stream into which the pictures of the video are coded such that each slice has encoded thereinto no more than one tile;
• and
• a set of one or more gathering tracks, each set of which is associated with a respective one of a plurality of positions of the section formed by a corresponding subset of the tiles and comprising construction instructions indicating a synthesis of a section-position-specific video data stream into which pictures showing the scene's section at the respective position are coded by
• signaling replacements for first portions of slices having encoded thereinto any tile of the subset of tiles from the source tracks, and/or
• copying second portions of the slices having encoded thereinto any tile of the subset of tiles.

A method for video streaming comprising

• receiving slices of a video data stream into which pictures of a video are coded each of which shows a scene, wherein the pictures are spatially subdivided into tiles and each slice has encoded thereinto no more than one tile;
• and
• rendering available to the client a streaming of a stream concerning a section of the scene, the stream being formatted in a file format and comprising
• a set of one or more source tracks incorporating the slices into which tiles within the section, being a set of one or more tiles wide, 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, by
• signaling replacements for first portions of the slices incorporated into the one or more source tracks, and/or
• instructing to copy second portions of the slices incorporated into the one or more source tracks.

A method for retrieving from a video streaming server a video concerning a section of a scene, the method comprising

• retrieving 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 each slice of the video data stream has encoded thereinto no more than one tile, the subset of slices incorporating the slices into which tiles within the section being a set of one or more tiles wide are encoded;
• and
• a set of one or more gathering tracks comprising construction instructions indicating a synthesis of a section-position-specific video data stream into which pictures showing the scene's section are encoded;
• synthesizing the section-specific video data stream according to construction instructions in the set of one or more gathering tracks by
• replacing first portions of the slices incorporated into the one or more source tracks by replacements signaled by the construction instructions, and/or
• copying second portions of the slices incorporated into the one or more source tracks,
• subjecting the section-position-specific video data stream to decoding by a video decoder.

A non-transitory digital storage medium having a computer program stored thereon to perform the method for video streaming comprising

• receiving slices of a video data stream into which pictures of a video are coded each of which shows a scene, wherein the pictures are spatially subdivided into tiles and each slice has encoded thereinto no more than one tile;
• and
• rendering available to the client a streaming of a stream concerning a section of the scene, the stream being formatted in a file format and comprising
• a set of one or more source tracks incorporating the slices into which tiles within the section, being a set of one or more tiles wide, 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, by
• signaling replacements for first portions of the slices incorporated into the one or more source tracks, and/or
• instructing to copy second portions of the slices incorporated into the one or more source tracks,
• when said computer program is run by a computer.
