Abstract: The present technology discloses communication in a communications network. A source node receives a media file from a client device in the communications network. Contextual information in the file is obtained that is descriptive of content in the medial file. When a match to the media file is found, the contextual information is accessed from storage. Otherwise, the contextual information is generated by the source node by extracting attributes from metadata in the media file. The media file is then transmitted over a first data path, and the contextual information is transmitted over a second data path, where the first data path has a higher latency than the second data path such that the contextual information arrives at the destination node prior to the media file.

Abstract: This application discloses a retransmitted data sending method, a retransmitted data receiving method, and a related apparatus, and relates to the field of communications technologies. In this solution, a transmit end generates a retransmitted codeword based on information bits of each codeword corresponding to an incorrect MPDU, where the retransmitted codeword includes a codeword having some of information bits included in the incorrect MPDU. For the codeword having some of information bits included in the incorrect MPDU, the transmit end punctures a correctly received information bit in the codeword, and then sends the information bit. In this way, a receive end may directly perform combined decoding or joint decoding on an LLR of a codeword of a retransmitted MPDU and an LLR of a codeword of an MPDU that is incorrectly received last time. This improves transmission efficiency and transmission reliability.

Abstract: Embodiments of this application provide a volume adjustment method and device, and a system. The method includes: A first terminal device sends a first playback request to a server, where the first playback request carries a model of the first terminal device and an identifier of the first audio. The server determines a first volume value of the first audio based on the identifier of the first audio and the model of the first terminal device. The server determines, based on the first volume value and a preset volume threshold of the first terminal device, a first volume gain. The first terminal device determines, based on the first volume gain and a currently set second volume value, a first target volume value. The first terminal device adjusts volume of playing the first audio to the first target volume value.
