Embodiment 1

[0023] figure 1 The implementation flow of the VoIP server synchronous mixing method provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0024] In step S101 , the jitter buffer area pre-allocated for each VoIP client is detected.

[0025] In the embodiment of the present invention, in order to cache the voice data sent by the VoIP client, each VoIP client should be assigned a corresponding buffer area in advance to cache the voice data and sort the voice data, thereby effectively eliminating the use of UDP The data jitter problem caused by the protocol sending data.

[0026] In a specific implementation process, the jitter buffer area can be represented in the form of a linked list, so as to facilitate data storage and deletion and improve the utilization rate of the buffer area. Specifically, each node is a structure, and the information stored in the structure includes: the length of the data, the timestamp, the duration correspond...

Embodiment 2

[0034] figure 2 The implementation flow of the VoIP server synchronous mixing method provided by Embodiment 2 of the present invention is shown, and the details are as follows:

[0035] In step S201, the jitter buffer pre-allocated for each VoIP client is detected.

[0036] In the embodiment of the present invention, in order to cache the voice data sent by the VoIP client, each VoIP client should be assigned a corresponding buffer area in advance to cache the voice data and sort the voice data, thereby effectively eliminating the use of UDP The data jitter problem caused by the protocol sending data.

[0037] In step S202, it is judged whether the current detection time exceeds the preset detection time, if yes, execute step S207, otherwise, execute step S203.

[0038] In the embodiment of the present invention, the detection time is counted to determine whether each detection time exceeds the preset detection time, and the detection time will have a great influence on the...

Embodiment 3

[0049] image 3 The structure of the VoIP server synchronous mixing system provided by the third embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0050] The buffer detection unit 31 detects the jitter buffer pre-allocated for each VoIP client.

[0051] In the embodiment of the present invention, in order to cache the voice data sent by the VoIP client, each VoIP client should be assigned a corresponding buffer area in advance to cache the voice data and sort the voice data, thereby effectively eliminating the use of UDP The data jitter problem caused by the protocol sending data.

[0052] When detecting that there is data in the jitter buffers corresponding to all VoIP clients, the first data packet obtaining unit 32 obtains a data packet from the jitter buffers corresponding to each VoIP client.

[0053] In the embodiment of the present invention, when ...

Abstract

The invention is applicable to the technical field of computers, and provides a VoIP (Voice Over Internet Protocol) server synchronous sound mixing method and system. The method comprises the following steps: detecting jiggle cache areas for distributing all VoIP client sides at advance; when data of all the VoIP client sides exits in the corresponding jiggle cache areas, acquiring data packages form the jiggle cache areas corresponding to all the VoIP client sides; decoding the data packages acquired, and carrying out the sound mixing processing on the decoded data according to the preset sound mixing algorithm; and sending the sound-mixed data to all the VoIP client sides. Through the arrangement of the jiggle cache areas, the data jiggle during the sound mixing process is eliminated effectively, and the sound mixing effect is improved, which increases the conversation experiment of VoIP users.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a VoIP server synchronous mixing method and system. Background technique [0002] With the advancement of network technology, VoIP (Voice over Internet Protocol, VoIP) has been more and more widely used because of its low call cost and good network integration. The teleconferencing system based on the Internet (IP network) can be built using the original network lines and equipment of the enterprise, and it is very convenient to use, thereby reducing the cost of the enterprise. [0003] Voice mixing is an important part of VoIP teleconferencing system and multimedia conference system. The current mixing solution adopts the traditional decoding-mixing-encoding mode. However, because voice conferencing systems have relatively high requirements for delay control, most VoIP teleconferencing systems use User Datagram Protocol (UDP) to send audio data packets, because th...
