transmit, to a receiver apparatus, an indication of a number of subpictures the sender apparatus supports in an encoded image data [Paragraph [0033]-[0036], [0041]-[0043], [0071]-[0076], [0098]-[0122], [0138]-[0141], Figs. 4-5, 8, Step 804, content provider transmits spatial manifest file (SMF) to client as receiver apparatus, wherein SMF comprises data structure comprising spatial segments comprising metadata that includes identifiers, as indication, of first, second, and third MPD video elements, wherein each video element associated with spatial segment identifiers of 2x4 HEVC tiles, 2x4 HEVC tiles, and 2x2 HEVC tiles, respectively];
receive, from the receiver apparatus, as a response to the indication of the number of subpictures the sender apparatus supports in the encoded image data, an indication of a preferred number of subpictures allowed in the encoded image data; determine a number of subpictures to include in the encoded image data based, at least partially, on the indication of the preferred number of subpictures allowed in the encoded image data [Paragraph [0033]-[0036], [0041]-[0043], [0071]-[0076], [0098]-[0122], [0138]-[0141], Figs. 4-5, 8, step 808, wherein DASH client as receiver apparatus, uses information in MPD to request video data, using the metadata of the HEVC-tiled video streams defined in SMF in order allow a client to select a particular ROI (e.g. a spatial segment) and to configure the decoder before the HEVC-tiled video data are received by the client. This metadata may include for example: information for determining the number and/or size of HEVC-tiles in the selected spatial segment using (e.g., the number of HEVC-tiles represented as a SubRepresentation), as the preferred number of subpictures allowed in encoded image data];
partition a bitstream representing an image data into subpictures, an amount of which corresponds to the determined number of subpictures [Paragraph [0033]-[0036], [0043], [0059]-[0063], [0071]-[0076], [0086]-[0090], [0098]-[0122], [0138]-[0141] & [0118], The HEVC encoder may be configured to divide video frames 100 in the HEVC stream in so-called HEVC tiles 102, wherein a HEVC tile is a rectangular area defined by a particular grouping of CTUs, and when using a HAS protocol, the spatially divided, independently decodable video data (i.e. the video data of the spatial segments) may be temporally divided in so-called temporal segments accordingly with client’s desired video data request, as in accordance with desired number of HEVC tiles or subset of HEVC tiles (ROI)];
generate an encoded bitstream comprising said subpictures [Paragraph [0101], the video frames of the source file may be encoded into a HEVC-tiled video file or stream comprising one or more (independently) decodable Spatial Segments];

However, Thomas does not explicitly disclose the sender apparatus to deliver required parameter sets for said subpictures to said receiver apparatus.
Wang teaches the sender apparatus to deliver required parameter sets for said subpictures to said receiver apparatus [Paragraph [0089] & [00115]-[00116], the bitstream, which includes a sequence parameter set and picture parameter sets containing subpicture mappings, is transmitted toward a decoder].
It would have been obvious to the person of ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus disclosed by Thomas to integrate and utilize parameter sets as described in Wang as above, to ensure efficient signaling of subpicture identifiers (IDs) even when the subpicture IDs change within the coded video sequence (CVS) in application scenarios involving both sub-bitstream extraction and sub-bitstream merging. The efficient signaling is accomplished by setting flags in the sequence parameter set (SPS) or the picture parameter set (SPS) to indicate whether subpicture IDS in the CVS may change and, if so, where the subpicture IDs are located. This reduces redundancy and increases coding efficiency (Wang, Paragraph [0003]-[0006]).
However, Thomas and Wang do not explicitly disclose wherein the number of subpictures the sender apparatus supports in the encoded image data is greater than the preferred number of subpictures allowed in the encoded image data.
Boyce teaches wherein the number of subpictures the sender apparatus supports in the encoded image data is greater than the preferred number of subpictures allowed in the encoded image data [Pgs. 6-7, ll. 7-2, In some embodiments of the syntax, the number of sub-pictures is limited to 256, with the highest value reserved to enable an extension if support for more sub-pictures is desired, further for 360 video coding using cube maps, each of the 6 cube faces can be split into 4 regions, to make 24 sub-pictures (144 sub-pictures)].

In some embodiments, information is received, from a decoder, about PTL parameters of the decoder and the one or more extracted bitstreams are generated to conform to the PTL parameters of the decoder.].
