Video stream transmission method and related device and system

A video stream transmission method, comprising:

• receiving, by a server, a target request sent by a client terminal device, wherein the target request comprises information about a corresponding target spatial location of a target spatial object that needs to be presented upon request by the client terminal device in a virtual reality VR content component;
• searching, by the server based on the target spatial location information, for the corresponding target spatial object in the VR content component;
• obtaining, by the server, information about a multiplex video stream that is obtained by performing preset multiplexing processing on an original video stream corresponding to the target spatial object;
• and
• sending, by the server, a target request feedback to the client in response to the target request, wherein the target request feedback comprises the information about the multiplex video stream,
• wherein the obtaining, by the server, information about a multiplex video stream that is obtained by performing preset multiplexing processing on an original video stream corresponding to the target spatial object comprises:
• dividing, by the server, the target spatial object into N sub-spatial objects, and dividing the original video stream based on the N sub-spatial objects, to generate N corresponding sub-video streams, wherein N is natural number greater than 1;
• and
• obtaining, by the server, information about N multiplexed sub-video streams that are obtained by separately performing the preset multiplexing processing on the N sub-video streams.

A client terminal device, comprising:

• at least one processor;
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
• send a target request to a server, wherein the target request comprises information about a corresponding target spatial location, of a target spatial object that needs to be presented upon request by the client terminal device, in a virtual reality VR content component;
• receive a target request feedback by which the server responds to the target request, wherein the target request feedback comprises information about a multiplex video stream that is obtained by performing preset multiplexing processing on an original video stream corresponding to the target spatial object;
• and
• perform video parsing and presentation based on the information about the multiplex video stream, wherein the information about the multiplex video stream comprises information about N multiplexed sub-video streams that are respectively obtained by performing preset multiplexing processing on N sub-video streams, wherein the N sub-video streams are corresponding sub-video streams generated by dividing the target spatial object into N sub-spatial objects and dividing the original video stream based on the N sub-spatial objects, wherein N is a natural number greater than 1, wherein the target request feedback further comprises multiplexing description information, and wherein the multiplexing description information comprises at least one of the following:
• a quantity N of the sub-video streams that is comprised in the information about the multiplex video stream;
• a starting location offset, in the information about the multiplex video stream, of a starting sub-video stream of the N sub-video streams;
• a size of the N multiplexed sub-video streams;
• spatial location information, in the VR content component, respectively corresponding to the N multiplexed sub-video streams;
• resolution information of the N multiplexed sub-video streams;
• a video stream multiplexing type of the N multiplexed sub-video streams;
• or resolution information of the N sub-video streams.

A server, comprising:

• search, based on the target spatial location information, for the corresponding target spatial object in the VR content component;
• obtain information about a multiplex video stream that is obtained by performing preset multiplexing processing on an original video stream corresponding to the target spatial object;
• and
• send a target request feedback to the client in response to the target request, wherein the target request feedback comprises the information about the multiplex video stream;
• wherein obtaining information about the multiplex video stream that is obtained by performing preset multiplexing processing on the original video stream corresponding to the target spatial object comprises:
• dividing the target spatial object into N sub-spatial objects, and dividing the original video stream based on the N sub-spatial objects, to generate N corresponding sub-video streams, wherein N is natural number greater than 1;
• and
• obtaining information about N multiplexed sub-video streams that are obtained by separately performing the preset multiplexing processing on the N sub-video streams.
