Embodiments of this application provide a data processing method, apparatus, and device for point cloud media, and a storage medium. The method includes: acquiring information of an i.sup.th attribute component of point cloud media, the point cloud media including N attribute components, the i.sup.th attribute component being any one of the N attribute components, the information of the i.sup.th attribute component being used for indicating at least one of a mandatory and a priority of the i.sup.th attribute component, both N and i being positive integers and i∈[1, N]; and parsing the i.sup.th attribute component based on the information of the i.sup.th attribute component. 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.

Embodiments of the present invention disclose a method of content-layer based compression of a video being broadcasted over a network. The method may include: receiving a video stream comprising a plurality of video stream frames; identifying in at least some of the plurality of video stream frames at least two content-layers of predefined content-layers to yield corresponding at least two content-layer streams, wherein each of the at least two content-layer streams is associated with one of the at least two content-layers; and compressing each of the at least two content-layer video streams according to predetermined parameters of the content-layer associated with the respective content-layer video stream and according to available resources of the network to yield corresponding at least two compressed content-layer streams.

A user of a storage system can upload files for a media asset, which can include a high quality media file and various related files. As part of the upload process, the storage system can extract metadata that describes the media asset. The user can specify one or more lifecycle policies to be applied for storage of the asset, and a rules engine can ensure the application of the one or more policies. The rules engine can also enable the use of simple media processing workflows. A filename hashing approach can be used to ensure that the segments and files for the asset are stored in a relatively random and even distribution across the partitions of the storage system. As part of the lifecycle for the asset, the high quality media file can be moved to less expensive storage once transcoding of the asset or another such action occurs.

In a method for image transmitting executed in a transmitting device, three data transmitting channels are established, the three data transmitting channels are a first channel, a second channel and a third channel. An image of a video is obtained, and the image is divided into a region of interest and a background region. A first data of the region of interest and a second data of the background region are obtained, and the first data is encoded through fountain coding to obtain a third data. The first data, the second data, and the third data are respectively transmitted through the first channel, the second channel, and the third channel to a receiving device. A network condition is received, and whether the network condition matches a preset condition is determined. When the network condition matches the preset condition, the first data is compensated according to a first preset algorithm.

Systems, methods and apparatus for processing image data are described. One example method includes performing a conversion between a visual media file and a bitstream. The visual media file comprises image items each comprising a sequence of one or more pictures according to a media file format, and the bitstream comprises access units each comprising one or more pictures each belonging to a layer according to a video coding format. The video coding format defines multiple profiles. The media file format specifies that the bitstream is represented in a file having a specific brand, and that one or more profiles used for representing the video in the bitstream are agnostic of the specific brand.
