Embodiment Construction

[0056]The basic idea of ​​the present invention is: the voice sending terminal obtains the voice information, calculates the sound energy of the voice information, and sends the sound energy corresponding to the voice information to the voice conference server, and sends the voice information to the corresponding multicast address in the multicast network; The voice conference server compares the sound energy from multiple voice sending terminals, and after obtaining at least two channels of voice information with high energy, instructs the voice receiving terminal to obtain the corresponding at least two channels from the corresponding multicast address in the multicast network through signaling. Voice information: the voice receiving terminal mixes the at least two channels of voice information. The present invention reduces the sound mixing steps of the voice conference server by optimizing the deployment of the sound mixing function, thereby greatly improving the sound mixi...

Abstract

The invention discloses a method for implementing voice mixing, the method is applied to a system comprising a multicasting network, a voice conference server and at least two voice terminals, the method comprises following steps: the voice transmitting terminals acquire voice information, calculate the voice energies of the voice information, and transmit the voice energies corresponding to the voice information to the voice conference server, and transmit the voice information into the corresponding multicasting address in the multicasting network; the voice conference server compares the voice energies from a plurality of voice transmitting terminals, after obtaining at least two ways of voice information with large energies, the voice receiving terminals are indicated by the signaling to acquire corresponding at least two ways of voice information from the multicasting address corresponding in the multicasting network; the voice receive terminal mix the voices for at least two ways of voice information. According to the invention, the performance requirement of the voice mixing server can be reduced by the arrangement of the optimized functions, thereby improving the whole voice conference capacity to enable the voice mixing capacity of the system to be improved greatly under the condition with same hardware.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a voice mixing method, system and equipment. Background technique [0002] The voice conferencing system can realize voice communication of multiple users at the same time, such as figure 1 As shown, the current audio conferencing system includes an MCU (Multipoint Control Unit, multipoint controller) and multiple terminals. These terminals have different functions at different times, and are divided into a voice originating terminal and a voice receiving terminal. Among them, the voice initiating terminal encodes the voice information and aggregates it to the MCU, and the MCU decodes the information from each voice initiating terminal, mixes and encodes each decoded voice signal, and sends it to the voice receiving terminal; the voice receiving terminal After receiving the sound stream, decode and output. [0003] Because the MCU mixes all the voice signals, it ...
