Systems and methods for adaptively streaming video content to a wireless transmit/receive unit (WTRU) or wired transmit/receive unit may include obtaining a media presentation description that comprises a content authenticity, requesting a key for a hash-based message authentication code; receiving the key for the hash-based message authentication code, determining a determined hash for a segment of the media presentation description, requesting a reference hash for the segment from a server, receiving the reference hash for the segment from the server, and comparing the reference hash to the determined hash to determine whether the requested hash matches the determined hash.

An image capture apparatus obtains image data captured using an image sensor and then generates, as metadata, information relating to a state of the image capture apparatus at the time of capturing the image data as well as to the image data. The image capture apparatus comprises a first output circuit for outputting the image data in a first format to an external apparatus and a second output circuit for outputting a part of the metadata in a second format to the external apparatus. The second output circuit is from the first output circuit.

A method comprising: authoring a first section of a first media format, wherein the first section comprises type and length fields of the first section, wherein the type value of the first section of the first media format is such that allows parsers of the first media format ignore the first section; one or more entire sections complying with a second media format; and a section header of a bridge section complying with the second media format, wherein the section header comprises type and length fields; authoring a second section of the first media format, comprising type and length fields of the second section; and data complying with the second media format; and setting the content of the first section to be such that it allows parsers of the second media format ignore the type and length fields of the second section.

A transmission method includes generating one or more frames for content transfer using IP packets, and transmitting the one or more generated frames by broadcast. Each of the one or more frames contains a plurality of second transfer units, each of the plurality of second transfer units contains one or more first transfer units, each of the one or more first transfer units contains at least one of the IP packets, an object IP packet of the IP packets contains first reference clock information indicating time for reproduction of the content in data structure different from MMT packet data structure, the object IP packet being stored in a first transfer unit positioned at a head in the one or more frames, the one or more frames contains control information storing second reference clock information indicating time for reproduction of the content, and header compression processing on the object IP packet is omitted.

The present disclosure relates to methods and devices for facilitating using a streaming manifest including a profile signal for content encoded based on a encapsulation format. An example method disclosed herein includes identifying structures associated with first media, wherein the first media is associated with a first streaming format. The example method also includes generating a streaming manifest for the first media, wherein the streaming manifest maps the structures associated with the first media to structures associated with a second streaming format, and including an indication with the streaming manifest, wherein the indication identifies the streaming profile used to map the structures.

The techniques described herein relate to methods, apparatus, and computer readable media configured to provide video data for immersive media implemented by a server in communication with a client device. A request to access a stream of media data associated with immersive content at a point in time the client is first accessing the stream of media data for the immersive content is received from the client device. An initial portion of media data is determined, starting from the point in time the client requests to access, for the immersive content for delivery to the client device. In response to the request to access the stream of media data, the initial portion of media data is transmitted to the client device.

According to one embodiment, a streaming server that outputs chunk data obtained by dividing picture data into chunks as streaming data, comprises a chunk length determination unit, and a data generation unit. The chunk length determination unit that calculates a chunk length which is a time length of the chunk, and the data generation unit that generates the chunk data by dividing the picture data into the chunks in accordance with the chunk length.

Disclosed herein is a point cloud data transmission method. The transmission method may include encoding the point cloud data, encapsulating the point cloud data, and transmitting point cloud data. Disclosed herein is a point cloud data reception device. The reception device may include a receiver configured to receive the point cloud data, a decapsulator configured to decapsulate the point cloud data, and a decoder configured to decode the point cloud data.

Systems and methods for Dynamic Adaptive Streaming over HTTP (DASH) is provided. A method includes: obtaining an event message track including a plurality of event message boxes, the event message track configured to be processed by a Dynamic Adaptive Streaming over HTTP (DASH) client for displaying media content; obtaining an indicator that indicates each type of the plurality of event message boxes in the event message track; and providing the event message track to the DASH client or displaying media content based on the event message track.

A method includes performing a conversion between a video that includes at least a video tile and a bitstream of the video according to a rule. The rule specifies that a height of a slice in the video tile in units of coding tree units is derived based on a value of a first syntax element in the bitstream indicating a number of explicitly provided slice heights for slices in the video tile that includes the slice.
