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.

Abstract: A live broadcast method includes: receiving, by a live broadcast client, a push-stream address sent by the live broadcast management server; sending, by the live broadcast client, a proxy push-stream request to a live broadcast proxy client; and sending, by the live broadcast client, collected live broadcast data to the live broadcast proxy client, and pushing the live broadcast data to a live broadcast server over an uplink of a dedicated network connected to the live broadcast proxy client.

Abstract: Embodiments of the present disclosure disclose a live broadcast method and system, and a related device. The method in the embodiments of the present disclosure includes: receiving, by a live broadcast client, a push-stream address sent by the live broadcast management server; sending, by the live broadcast client, a proxy push-stream request to a live broadcast proxy client; and sending, by the live broadcast client, collected live broadcast data to the live broadcast proxy client, and pushing the live broadcast data to a live broadcast server over an uplink of a dedicated network connected to the live broadcast proxy client.

Abstract: A method for online application processing includes receiving an online application execution request from a client. An online application is executed. Local resource data of the client is acquired from the client. The local resource data of the client is used as input data of the online application for processing. Online application execution information is transmitted to the client in real time. In addition, a corresponding apparatus and system for online application processing are provided.
