摘要

The present disclosure disclose example video stream transmission methods and related devices and systems. One example method includes sending, by a client, a target request to a server, where the target request includes information about a corresponding target spatial location of a target spatial object that needs to be presented upon request by the client in a virtual reality VR content component. A target request feedback by which the server responds to the target request is received by the client, where the target request feedback includes 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. Video parsing and presentation based on the information about the multiplex video stream is performed by the client.

說明書

FIG. 14 is a schematic structural diagram of another server according to an embodiment of the present disclosure. As shown in FIG. 14, a server 40 includes a processor 401, a memory 402, and a transceiver 403. The processor 401, the memory 402, and the transceiver 403 may be connected by using a bus or in another manner.

Optionally, the server 40 may further include a network interface 404 and a power module 405.

The processor 401 may be a digital signal processing (Digital Signal Processing, DSP) chip.

The memory 402 is configured to store an instruction. In specific implementation, the memory 402 may use a read-only memory (English: Read-Only Memory, ROM for short) or a random access memory (English: Random Access Memory, RAM for short). In this embodiment of the present disclosure, the memory 402 is configured to store code of a video stream transmission program.

The transceiver 403 is configured to transmit and receive a signal.

The network interface 404 is used by the server 40 to perform data communication with another device. The network interface 404 may be a wired interface or a wireless interface.

The power module 405 is configured to supply power to each module of the server 40.

The processor 401 is configured to call the instruction stored in the memory 402 to perform the following operations:
