The method relates to the field of point cloud media technologies, and can improve parsing processing efficiency for point cloud media to a certain extent by indicating a mandatory and a priority of an attribute component of the point cloud media.

A method, apparatus and computer program product are provided to signal and store compressed point clouds in video encoding. The method, apparatus and computer program product may be utilized in conjunction with a variety of video formats. Relative to encoding of compressed point clouds, the method, apparatus and computer program product access a point cloud compression coded bitstream and cause storage of the point cloud compression coded bitstream. The point cloud compression coded bitstream comprises a texture information bitstream, a geometry information bitstream, and an auxiliary metadata bitstream. Relative to the decoding of compressed point clouds, the method, apparatus and computer program product receive a point cloud compression coded bitstream and decode the point cloud compression coded bitstream.

A transmitting device (30, 30a) is configured to transmit, to a receiving device (40, 40a), a plurality of video signals captured from different positions, the plurality of video signals being grouped by a plurality of groups depending on imaging positions at which the video signals are captured. The transmitting device (30, 30a) comprises: a controller (32) configured to assign an ID for identifying each of the plurality of groups; and a communication interface (37) configured to transmit a video signal to which the ID is assigned, to the receiving device (40, 40a).

The present disclosure relates to an image processing apparatus and method that enable linking between a 3D spatial region and an atlas tile group.

Link information is generated and signaled, in which the link information is stored in a file together with a bitstream of a point cloud expressing an object having a three-dimensional shape as a set of points, and the link information links a 3D spatial region of the point cloud with an atlas tile group. On the basis of the link information, the 3D spatial region and the atlas tile group that correspond to a desired three-dimensional space are selected. The present disclosure can be applied to, for example, an image processing apparatus, an information processing apparatus, an image processing method, an information processing method, or the like.

There is provided an information processing apparatus and method capable of more easily comparing 3D objects. Comparison information which is information for displaying a plurality of 3D objects of 6DoF content in a comparable manner is generated. Further, the plurality of 3D objects of the 6DoF content is displayed in a comparable manner on the basis of comparison information which is information for displaying the plurality of 3D objects in a comparable manner. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, an information processing system, and the like.

A method for providing media content by a server, the media content comprising media components, each media component comprising initialization data and media data, the method being carried out by the server for a preselection of a plurality of media components, obtaining an indication of which initialization data of the plurality of media components should be used by a client to process media data of the media components of the preselection; and describing the preselection in a media presentation description, the description of the preselection comprising references to each media component of the plurality of media components and the obtained indication.

Provided are methods and systems for controlling data such as content and/or application data transmitted to one or more user devices. One method can comprise receiving a request for first content and generating, in response to the request for the first content, a first transport stream comprising the first content and application data relating to a first application. At least a portion of the first transport stream is transmitted to a recipient device. An interruption in the transmission of the first transport stream is detected and a determination is made that only a first portion of the application data has been transmitted to the recipient device. A second transport stream including second content and a second portion of the application data is generated and transmitted.

Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.

The present invention provides a method of transmitting broadcast signals. The method includes, formatting input streams into Data Pipe (DP) data, Low-Density Parity-Check (LDPC) encoding the DP data according to a code rate, bit interleaving the LDPC encoded DP data, mapping the hit interleaved DP data onto constellations, building at least one signal frame including the mapped DP data, and modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) method and transmitting the broadcast signals having the modulated data, wherein the input streams include Audio/Video (A/V) data and service guide data, and wherein the Audio/Video (A/V) data and service guide data are included in first ISO base media file format (ISOBMFF) files.

A method of encapsulating an encoded bitstream representing one or more images, the encapsulated bitstream comprising a data part and a metadata part. The method including providing image item information identifying a portion of the data part representing a sub-image or an image of a single image; providing image description information comprising parameters including display parameters and/or transformation operators relating to one or more images and outputting said bitstream together with said provided information as an encapsulated data file, wherein the image description information is stored in the metadata part.
