Abstract: The present disclosure relates to a data transmission method and apparatus, and belongs to the field of Internet technology. The method includes: determining whether a to-be-sent video data packet exists each time a preset data sending cycle is reached; if the to-be-sent video data packet does not exist, selecting at least one video data packet, a number of times the at least one video data packet has been sent satisfying a preset sending-times condition and total data volume of the at least one video data packet satisfying a preset expected data-volume condition, from sent video data packets based on a number of times each of the sent video data packets has been sent, and determining a filling data packet according to selected video data packet; and sending the filling data packet to a receiving terminal.

Abstract: An audio coding method, comprising: obtaining an ith audio frame in n consecutive audio frames and obtaining an ith piece of coded data and an ith piece of redundant data based on the ith audio frame, wherein the ith piece of coded data is obtained by coding the ith audio frame, and the ith piece of redundant data is obtained by coding and buffering the ith audio frame, wherein n is a positive integer, and 1?i?n; and packing the ith piece of coded data and at most m pieces of redundant data before the ith piece of redundant data into an ith audio data packet, wherein m is a preset positive integer. An audio decoding method and a computer device are further provided.

Abstract: An audio coding and decoding method and device, and an audio coding and decoding system. The method comprises: obtaining an ith audio frame in n continuous audio frames; based on the ith audio frame, obtaining an ith piece of coded data and an ith piece of redundant data, where the ith piece of coded data is obtained by coding the ith audio frame, and the ith piece of redundant data is obtained by coding and buffering the ith audio frame, where i is a positive integer, n is a positive integer, and 1 <i <n; (202) and packing at most m pieces of redundant data before the ith piece of redundant data and the ith piece of redundant data to be an ith audio data packet, where m is a pre-set positive integer (203). The method can reduce latency caused by loss of an audio data packet.
