Abstract
A method and system are described wherein a terminal sends, to a server, a video request message that includes an identifier of a virtual reality (VR) video. The VR video comprises N sub-bitstreams. The terminal receives a video response message sent by the server. The video response message indicates multicast addresses respectively corresponding to the N sub-bitstreams, and the terminal determines a target sub-bitstream based on a current field of view of a user, and obtains the target sub-bitstream based on a multicast address corresponding to the target sub-bitstream. The multicast address is one of the multicast addresses, and the target sub-bitstream comprises at least one sub-bitstream of the N sub-bitstreams.
