Abstract

The invention discloses a system and method for adjusting volume in real time in a live broadcast process. The system is arranged at a live broadcast background and comprises a transcoder and a volume adjusting apparatus. The transcoder comprises an encoding unit and a decoding unit, wherein the encoding unit is used for decoding in real time a live broadcast audio and video uploaded to the live broadcast background so as to obtain original audio and video signals, and the encoding unit is used for encoding in real time the original audio and video signals so as to obtain encoded audio and video signals. The volume adjusting apparatus is arranged between the decoding unit and the encoding unit and is used for, according to a volume adjusting instruction, adjusting volume of the original audio and video signals output to the encoding unit by the decoding unit. According to the technical scheme provided by the invention, the volume can be adjusted in real time from a source end in a network live broadcast process, and thus better experience is provided for a user.

Description

technical field [0001] The invention belongs to the technical field of network video transmission and application, and more specifically relates to a system for adjusting volume in real time during a live broadcast, and a method for adjusting volume in real time during a live broadcast. Background technique [0002] Webcasting means that users can watch the ongoing live broadcast at the remote end through the network, and the live audio and video content watched by users is called live audio and video. [0003] In the prior art, the network anchor uses smart electronic devices such as PCs and mobile phones to collect audio and video through live streaming software such as obs (OpenBroadcasterSoftware), encodes the collected audio and video in real time, and transmits the encoded live audio and video to the live broadcast server ( live background). The audience sends a request to the live broadcast server to watch the live audio and video, and the live broadcast server perfo...
