Embodiment 1

[0059] This embodiment provides a volume adjustment method of a conference system, which can be used in a media platform. Such as figure 2 As shown, the method includes the following steps:

[0060] Step S11, acquiring audio data transmitted by conference terminals in the conference system.

[0061] Each conference terminal in the conference system collects the audio data of the participants in real time, and sends the collected audio data to the media platform in the conference system; or, in the case of offline audio data volume adjustment, several audio data can be pre-stored in the In the memory of each conference terminal; it only needs to ensure that the media platform can obtain the audio data, which can be used for volume adjustment.

[0062] Step S12, acquiring the volume of the audio data and the preset volume.

[0063] The media platform acquires the volume of each audio data and the preset volume. Wherein, the preset volume is preset by the user, and the princ...

Embodiment 2

[0076] This embodiment provides a volume adjustment method of a conference system, which can be used in a media platform. Such as image 3 As shown, the method includes the following steps:

[0077] Step S21, acquiring audio data transmitted by conference terminals in the conference system.

[0078] The conference terminal in the conference system collects the audio of the participants in real time, samples, quantizes, and encodes the audio information into discrete digital audio streams. When the digital audio code stream is encapsulated into a data frame for transmission, it is carried out according to the transmission protocol. Available audio transmission protocols include HTTP-based streaming media transmission protocol (HTTP LiveStreaming), real-time messaging protocol (Real Time Messaging Protocol, referred to as RTMP), and real-time transport protocol (Real-time Transport Protocol, referred to as RTP), etc. . Optionally, audio frame encapsulation may be performed a...

Embodiment 3

[0106] This embodiment provides a volume adjustment method of a conference system, which can be used in a media platform. Such as Figure 4 As shown, the method includes the following steps:

[0107] Step S31, acquiring audio data transmitted by conference terminals in the conference system.

[0108] It is the same as step S21 in Embodiment 2, and will not be repeated here.

[0109] Step S32, acquiring the volume and preset volume of the audio data.

[0110] It is the same as step S22 in Embodiment 2, and will not be repeated here.

[0111] Step S33, using the volume of the audio data and the preset volume to determine the volume change value.

[0112] It is the same as step S23 in Embodiment 2, and will not be repeated here.

[0113] In step S34, the volume adjustment amount is determined according to the magnitude relationship between the volume change value and the maximum volume gain value.

[0114] The media platform determines the magnitude of the volume adjustment...

Abstract

The invention discloses a volume adjustment method and device of a conference system. The method comprises the following steps: acquiring audio data transmitted by a conference terminal in a conference system; acquiring a volume and a preset volume of the audio data; according to the volume and the preset volume of the audio data, determining a volume changing value; on the basis of a relationshipbetween the volume changing value and a maximum volume gain value, determining a volume adjustment value; and adjusting the volume of the audio data based on the volume adjustment value. With settingof the maximum gain value of the volume, the sound shelter effect generated by the volume adjustment is avoided, so that conference mixing of the audio data transmitted by the conference terminal inthe conference system can be carried out, small sound shelter by the large sound is avoided, and the sound becomes clear. Meanwhile, other function modules of the conference system are not affected during the volume adjustment process, so that the system practicality is improved.

Description

technical field [0001] The invention relates to the technical fields of communication and mobile Internet, in particular to a volume adjustment method and device for a conference system. Background technique [0002] With the progress of society and the development of science and technology, the communication between people is becoming more and more frequent, and the way of communication is gradually changing from letters to telephones to video conference systems. However, except for letters, most of the other communication methods that carry information are audio and video data, and whether it is audio or video, sound plays an important role in communication. [0003] Taking the video conferencing system as an example, the current large-scale conference systems all use the central point as the processing center to provide services. During the video conferencing process, a large amount of audio data is transmitted to the central point processor for sound mixing processing. ...
