Abstract: A video coding mechanism for viewpoint dependent video coding is disclosed. The mechanism includes mapping a spherical video signal, stitched from multiple directional video signals, into a plurality of sub-picture video signals each containing a sequence of sub-pictures. The plurality of sub-picture video signals are encoded as a plurality of sub-picture bitstreams. The plurality of sub-picture bitstreams are composed into a plurality of sub-picture tracks to be compatible with a multi-bitstream merge function for reconstruction of the spherical video signal. A track level mergable indication is encoded within a track level box for the sub-picture tracks, which indicates the sub-picture tracks are compatible with the multi-bitstream merge function for reconstruction of the spherical video signal.

Abstract: A media data transmission method and an apparatus. The method includes: A client sends first information to a server. The client receives video data packets that correspond to a second target video picture and that are sent by the server. The first information is used to indicate spatial information of a region in which a first target video picture is located, and the first target video picture includes a video picture within a current viewport. The second target video picture includes the first target video picture, at least one of the video data packets corresponding to the second target video picture carries at least one piece of second information, and the second information is used to indicate spatial information of a region in which the second target video picture is located.

Abstract: An access network congestion control method, a base station device, and a policy and charging rules function network element are provided. The method includes the following steps: sending a congestion report to a policy and charging rules function network element (PCRF); receiving a radio frequency resource adjustment policy sent by the PCRF; and performing the radio frequency resource adjustment policy for the user equipment in the congested state and the user equipment in the over-served state. A corresponding base station device and PCRF are further disclosed. According to embodiments of the present application, when congestion occurs in a radio access network, radio frequency resources that are of user equipment in a congested state and that are of user equipment in an over-served state may be reallocated to ensure smooth communication.

Abstract: A method includes: obtaining, by a PCRF, actual rates of service flows processed by multiple user equipment; determining, by the PCRF, a congestion relief policy according to the obtained actual rates of the service flows processed by the multiple user equipment; and sending, by the PCRF, the congestion relief policy to a service flow pass-through node, so that the service flow pass-through node executes the congestion relief policy. It is determined, according to obtained actual rates of service flows processed by different user equipment, that an actual rate of a service flow processed by a user equipment is limited, so as to increase an actual rate of a service flow processed by another user equipment. This effectively relieves system congestion and improves user experience during congestion.
