Abstract: A three-dimensional audio signal coding method, apparatus, and encoder are described. The method includes, after obtaining a first correlation between a current frame of a three-dimensional audio signal and a representative virtual speaker set for a previous frame, the encoder determines whether the first correlation satisfies a reuse condition, where the first correlation is used to determine whether to reuse the representative virtual speaker set for the previous frame when the current frame is encoded. The method further encodes the current frame based on the representative virtual speaker set for the previous frame when the first correlation satisfies the reuse condition, to obtain a bitstream. A virtual speaker in the representative virtual speaker set for the previous frame is a virtual speaker used for encoding the previous frame of the three-dimensional audio signal.

Abstract: A three-dimensional audio signal encoding method and apparatus, and an encoder are provided, and relate to the multimedia field. The method includes: The encoder obtains a first quantity of current-frame initial vote values for a current frame of a three-dimensional audio signal. Then, the encoder obtains, based on the first quantity of current-frame initial vote values and a sixth quantity of previous-frame final vote values, a seventh quantity of current-frame final vote values that are of a seventh quantity of virtual loudspeakers and that correspond to the current frame. Further, the encoder selects a second quantity of current-frame representative virtual loudspeakers from the seventh quantity of virtual loudspeakers based on the seventh quantity of current-frame final vote values. The encoder encodes the current frame based on the second quantity of current-frame representative virtual loudspeakers, to obtain a bitstream.

Abstract: This application provides a method and an apparatus for determining a virtual speaker set. The method for determining a virtual speaker set includes: determining a target virtual speaker from F preset virtual speakers based on a to-be-processed audio signal, where each of the F virtual speakers corresponds to S virtual speakers, F is a positive integer, and S is a positive integer greater than 1; and obtaining, from a preset virtual speaker distribution table, respective position information of S virtual speakers corresponding to the target virtual speaker, where the virtual speaker distribution table includes position information of K virtual speakers, the position information includes an elevation angle index and an azimuth angle index, K is a positive integer greater than 1, F≤K, and F×S≥K. This application can improve audio signal playback effect.

Abstract: This application provides a method for determining a traffic transmission path on a network. The method includes: sending, by a first L3GW, a first packet to a host on a same subnet as the first L3GW; receiving, by the first L3GW, a response packet for the first packet that is sent by the destination host; and generating, by the first L3GW, a route pointing to the destination host based on the response packet for the first packet, and sending the route to the first network device. By using the foregoing method, a problem of a traffic detour when a core router sends traffic to the destination host in a data center can be avoided.
