Problems solved by technology

However, this solution also has disadvantages. If the English venue speaks, the translator translates it into Chinese, and each venue will hear English first, and then Chinese. But in fact, the Chinese venue does not need to hear the English speech, and the English There is also no need to hear the translated Chinese speeches, which makes the participants have to hear a lot of useless information. Chinese and English are mixed, which makes the meeting order chaotic, and the participants are prone to fatigue, and the translation process will slow down the meeting rhythm , the efficiency decreases
[0013] If you consider that there may be three or more languages ​​in the conference, and there may be multiple venues speaking at the same time, considering the effect after the audio mixing, the above two solutions will lead to poor conference quality and cannot be applied

specific Embodiment approach 1

[0067] The conference terminal and the translation terminal (the conference terminal at the translation venue is referred to as "translation terminal" for short, the same below) only use one input and output interface, the MCU adopts multi-channel audio mixing, and the MCU configures the language corresponding to the conference terminal and the conference as the translation terminal terminal. In this solution, there are no special requirements for conference terminals and translation terminals, and most of the work is done by the MCU. Each part is detailed as follows:

[0068] As shown in Figure 6, the conference terminal collects the local input audio signal, encodes it and sends it to the MCU. Receive the audio code stream sent by the MCU, and play it after decoding. In this way, the terminal does not need to distinguish between input and output languages.

[0069] The translation terminal is responsible for language translation of speeches at each venue, such as translat...

specific Embodiment approach 2

[0082] The conference terminal and the translation terminal only use one input and output interface. The conference terminal needs to inform the MCU of its own language through signaling, or inform the MCU that it is a translation terminal. The MCU samples the multi-channel mix. The codec used by the conference terminal, translation terminal and MCU is a mono codec. Each part is detailed as follows:

[0083] The realization of the conference terminal is the same as that of the specific implementation mode 1, and the difference from the first embodiment is that: as shown in Figure 10, the conference terminal supports the language configuration of the conference site, and confirms the language of the conference site to the MCU through signaling such as H.245, for example, the conference terminal selects the language If it is Chinese, the MCU is informed that the conference terminal belongs to the Chinese conference site.

[0084] The realization of the translation terminal is ...

specific Embodiment approach 3

[0087]The conference terminal and the translation terminal only use one input and output interface. The conference terminal needs to inform the MCU of its own language through the in-band method, or inform the MCU that it is a translation terminal. The MCU samples the multi-channel mix. The codec used by the conference terminal, translation terminal and MCU is a mono codec. Each part is detailed as follows:

[0088] The implementation of the conference terminal is the same as that of the second embodiment, and the difference between the second embodiment is that the conference terminal receives the input audio data, encodes it, and sends the coded code stream and the language information corresponding to the code stream to the MCU together, as shown in Figure 10 , For example, the Chinese conference terminal adds a Chinese logo in the code stream sent to the MCU, and the English conference terminal adds an English logo in the code stream sent to the MCU. Instead of using sig...

Abstract

The invention discloses a multi-language conference system that includes conference terminal for processing speak and sending it to multi-point control unit and processing the audio frequency data and outputting it, at least one conference terminal is used for translating the speak, processing the audio frequency data after translated and sent it to the multi-point control unit. The multi-point control unit is used for conducting mixing process to the audio data of different sound track from the conference terminal according language kind and then sending the audio data processed to the conference terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for realizing multilingual conferences. Background technique [0002] In recent years, with the development of communication technology, video conferencing has been widely developed and applied. Video conferencing can be understood as a video conferencing business in the usual sense. Through multimedia communication means, using TV equipment and communication networks to hold meetings, it can simultaneously realize the interactive functions of images, voice, and data between two or more locations. As shown in FIG. 1 , a video conference generally consists of several parts such as a video terminal, a transmission network, and a multipoint control unit (MCU, Multipoint Control Unit). [0003] Video terminal equipment mainly includes video input / output equipment, audio input and output equipment, video codec, audio codec, information communication equipme...
