Embodiments of this application provide a multicast/broadcast service communication method and an apparatus, and relate to the communication field, to reduce network resource overheads. The method is as follows: A terminal device determines a first multicast/broadcast service, where the first multicast/broadcast service is a multicast/broadcast service that the terminal device is to leave. The terminal device sends a first message, where the first message carries identification information of the first multicast/broadcast service. Embodiments of this application are applied to a mobile communication system such as 5G.

A split streaming system and method are provided in which a stream of data (that can be video, audio or textual data) is split and sent over a plurality of stream reflectors to a stream recipient. Each stream reflector performs time gradient replacement to manage the split streaming.

There is provided a technology capable of reducing the processing load on a server apparatus side in cloud rendering. A server apparatus according to the present technology includes a controller. The controller groups terminal apparatuses each having a viewing position within an identical segment on the basis of viewing position information of each terminal apparatus within a viewing region including a plurality of segments, and transmits common video information to each of the grouped terminal apparatuses by multicasting.

A method for accessing a serving network includes: obtaining, by a user plane network element, an access message, where the access message is for a terminal accessing a serving network, and where the access message includes authentication information of the terminal in the serving network; and sending, by the user plane network element, the access message to the serving network. The method for accessing serving network and the communications apparatus that are provided in the embodiments of this application enable a terminal to access a serving network using an access network, and expand a usage scenario of the serving network.

A content protection system for satellite-based content delivery is provided, including a satellite content receiver. The satellite content receiver may include one or more processors and a non-transitory processor readable medium, and be in communication with a satellite antenna. The satellite content receiver may receive a first portion of streaming media content, transmitted by a content security host system using multicast communication. The first portion of the streaming media content may be stored, and later accessed in response to a user command. A second portion of the streaming media content including data missing from the first portion of the streaming media content may be identified. The second portion may be requested from the content security host system and received by the satellite content receiver. The first and second portions of the streaming media content may be combined to reconstruct the streaming media content, which may then be output.

A solution is disclosed for providing automatic multicast address assignment and conflict resolution for AV streams multicast over a networked AV system. The solution includes a device for monitoring the system for messages associated with AV streams multicast over the system and implementing a conflict resolution protocol when a conflict of multicast addresses is detected, where the conflict resolution protocol utilizes automatically randomly selecting a preliminary multicast address from a defined range of addresses.
