Regarding claim 8, Takahashi discloses wherein a media file contains a track data box (paragraph [107, fig.4, Takahashi discloses a file structure with a “TrackBox” or a track data box), and the track data box is for indicating the attribute component track to which the attribute data having the encoding and decoding dependency relationship in the point cloud bitstream belongs (paragraph [91], fig.3, Takahashi discloses the presence of independent slice units and dependent slice units, and that , wherein paragraph [93], Takahashi discloses that attribute data of dependent slice #2 is dependent on attribute data of independent slice #1, and paragraph [94], Takahashi discloses that attribute data of dependent slice #6 is dependent on attribute data of dependent slice #2, and attribute data of dependent slice #6 is also indirectly dependent on attribute data of independent slice #1, and paragraph [95], Takahashi discloses that attribute data of dependent slice #3 is dependent on attribute data of independent slice #1, and paragraph [96], Takahashi discloses that attribute data of dependent slice #7 is dependent on attribute data of dependent slice #3, and attribute data of dependent slice #7 is also indirectly dependent on attribute data of independent slice #1, and paragraph [108], Takahashi discloses GPCCDecoderConfigurationRecord includes data from attribute parameter set (APS) and a tile inventory depending on a sample entry type as illustrated as fig.3 for clearly associating the dependency information of the attribute data onto the GPCCDecoderConfigurationRecord in the metadata area of the media content file for providing the proper information to the decoder for establishing the cross-attribute dependency indication information based on encoding/decoding relationship between attribute data in the point cloud bitstream); and
the cross-attribute dependency indication information (paragraph [91], fig.3, Takahashi discloses the presence of independent slice units and dependent slice units, and that , wherein paragraph [93], Takahashi discloses that attribute data of dependent slice #2 is dependent on attribute data of independent slice #1, and paragraph [94], Takahashi discloses that attribute data of dependent slice #6 is dependent on attribute data of dependent slice #2, and attribute data of dependent slice #6 is also indirectly dependent on attribute data of independent slice #1, and paragraph [95], Takahashi discloses that attribute data of dependent slice #3 is dependent on attribute data of independent slice #1, and paragraph [96], Takahashi discloses that attribute data of dependent slice #7 is dependent on attribute data of dependent slice #3, and attribute data of dependent slice #7 is also indirectly dependent on attribute data of independent slice #1, and paragraph [108], Takahashi discloses GPCCDecoderConfigurationRecord includes data from attribute parameter set (APS) and a tile inventory depending on a sample entry type as illustrated as fig.3 for clearly associating the dependency information of the attribute data onto the GPCCDecoderConfigurationRecord in the metadata area of the media content file for providing the proper information to the decoder for establishing the cross-attribute dependency indication information based on encoding/decoding relationship between attribute data in the point cloud bitstream) is represented as a cross-attribute dependency information data box (paragraph [107, fig.4, Takahashi discloses a file structure with a “TrackBox” or a track data box, wherein GPCCDecoderConfigurationRecord comprises the cross-attribute dependency information, and Takahashi’s TrackBox comprises SampleTableBox which comprises the “GPCCDecoderConfigurationRecord”, thus the cross-attribute dependency information data box is within the track data box), and the cross-attribute dependency information data box is set in the track data box (paragraph [107, fig.4, Takahashi discloses a file structure with a “TrackBox” or a track data box, wherein GPCCDecoderConfigurationRecord comprises the cross-attribute dependency information, and Takahashi’s TrackBox comprises SampleTableBox which comprises the “GPCCDecoderConfigurationRecord”, thus the cross-attribute dependency information data box is within the track data box).
Takahashi does not disclose wherein the media file contains a track group type data box, and the track group type data box is for indicating the attribute component track to which the attribute data having the encoding and decoding dependency relationship in the point cloud bitstream belongs; and the cross-attribute dependency indication information is represented as a cross-attribute dependency information data box, and the cross-attribute dependency information data box is set in the track group type data box. However, Huang teaches the concept of a track group type data box (paragraph [54], Huang discloses TrackGroupTypeBox for a media file structure).
Since Takahashi teaches “…wherein a media file contains a track data box, and the track data box is for indicating the attribute component track to which the attribute data having the encoding and decoding dependency relationship in the point cloud bitstream belongs; and the cross-attribute dependency indication information is represented as a cross-attribute dependency information data box”, and Huang discloses the implementation of a “track group type data box”, therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Takahashi and Huang together as a whole for ascertaining the limitation of “…wherein the media file contains a track group type data box, and the track group type data box is for indicating the attribute component track to which the attribute data having the encoding and decoding dependency relationship in the point cloud bitstream belongs; and the cross-attribute dependency indication information is represented as a cross-attribute dependency information data box, and the cross-attribute dependency information data box is set in the track group type data box” in order to efficiently capture, compress, reconstruct and render point cloud data (Huang’s paragraph [16]).
Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Takahashi (US 2023/0291918) in view of Oh (US 2021/0029187).
Regarding claim 13, Takahashi discloses wherein the media file comprises a track ((paragraph [68], Takahashi discloses that L-HEVC file format can have a file with a single or plural individual tracks of ISOBMFF, and paragraph [122], Takahashi discloses that in the media file, there can be one or more tracks), the track contains one or more samples (paragraph [199], Takahashi discloses that plural samples can be stored in the tracks; paragraph [107], fig.4, Takahashi discloses the file structure of the media content file in that the GPCC track with a MediaDataBox that comprises multiple samples), and each of the one or more samples corresponds to one frame in the point cloud media (paragraph [90], Takahashi discloses that each sample corresponds to one frame of a moving image in a point cloud).
Takahashi does not disclose the media file further comprises a component information data box, and the component information data box contains a type of a component in the track; in response to the type of the component being attribute data, the component information data box further comprises an attribute identifier field, the attribute identifier field is for indicating an identifier of current attribute data, and the current attribute data refers to attribute data being decoded. However, Oh teaches the media file further comprises a component information data box (paragraph [548], Oh discloses the concept of a media data box that comprises information about attributes of point cloud data from G-PCC sample, and paragraph [549], Oh discloses a moov box, wherein a moov box is a data box that can comprise component information from the metadata that is necessary for decoding and playback of media data, as well as information from the tracks and samples of the media file), and the component information data box contains a type of a component in the track (paragraph [371], fig.25, Oh discloses attribute types comprises color, reflectance and frame index, and paragraph [17], Oh discloses that the bitstream can be stored in either a single track or in plural tracks that includes attribute data components, and paragraph [19], Oh discloses that the type of data in the payload can be included within the parameter set or attribute bitstream, and also paragraph [265], Oh discloses metadata track information can be encapsulated for comprising a type of component in the tracks); in response to the type of the component being attribute data (paragraph [368], Oh discloses known_attribute_label [i] field is an attribute identifier field, wherein if the known_attribute_label [i] is set equal to zero to specify the i-th attribute is color and if the known_attribute_label [i] is set equal to one, then the i-th attribute is reflectance), the attribute identifier field is for indicating an identifier of current attribute data (paragraph [368], Oh discloses known_attribute_label [i] field is an attribute identifier field, wherein if the known_attribute_label [i] is set equal to zero to specify the i-th attribute is color and if the known_attribute_label [i] is set equal to one, then the i-th attribute is reflectance, thus, the known_attribute_label [i] field indicates the current attribute data), the component information data box further comprises an attribute identifier field (paragraph [368], Oh discloses known_attribute_label [i] field is an attribute identifier field, wherein if the known_attribute_label [i] is set equal to zero to specify the i-th attribute is color and if the known_attribute_label [i] is set equal to one, then the i-th attribute is reflectance), the attribute identifier field is for indicating an identifier of current attribute data (paragraph [368], Oh discloses known_attribute_label [i] field is an attribute identifier field, wherein if the known_attribute_label [i] is set equal to zero to specify the i-th attribute is color and if the known_attribute_label [i] is set equal to one, then the i-th attribute is reflectance, thus, the known_attribute_label [i] field indicates the current attribute data), and the current attribute data refers to attribute data being decoded (paragraph [368], Oh discloses known_attribute_label [i] field is an attribute identifier field, wherein if the known_attribute_label [i] is set equal to zero to specify the i-th attribute is color and if the known_attribute_label [i] is set equal to one, then the i-th attribute is reflectance, thus, the known_attribute_label [i] field indicates the current attribute data, and paragraph [114], Oh discloses implementing a point cloud video decoder 10006 for performing the decoding of point cloud data based on the received encoded bitstream that includes attribute data and metadata).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Takahashi and Oh together as a whole for improving parallel processing and scalability of point cloud data transmission (Oh’s paragraph [30]).
