specific Embodiment approach 1

[0070] 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:

[0071] Such as Image 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.

[0072] The translation terminal is responsible for language translation of speeches at each venue, such as translatin...

specific Embodiment approach 2

[0085] 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:

[0086] The realization of the conference terminal is the same as that of the specific implementation mode 1, and the difference from the implementation mode 1 is: if 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, if the conference terminal selects the language as Chinese, it will inform the MCU that the conference terminal belongs to the Chinese conference site.

[0087] The realization of the translation terminal is the same ...

specific Embodiment approach 3

[0090] 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 or inform the MCU that it is a translation terminal through an in-band method. 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:

[0091] 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 encoded code stream and the language information corresponding to the code stream to the MCU together. See 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 signaling...

Abstract

The invention discloses a system for realizing multi-language conference; the system comprises conference terminals which are used for processing the speech in the conference and transmitting to a multipoint control unit, and processing and outputting the audio data from the multipoint control unit; wherein, at least one conference terminal is used for interpreting the speech in the conference, processing the interpreted audio data and transmitting the data to the multipoint control unit; and the multipoint control unit which is used for carrying out channel separation and sound mixing to theaudio data from the conference terminal according to languages, and transmitting the audio data to the conference terminal; the invention further discloses a method for realizing multi-language conference; the system and the method of the invention realize that in a multipoint conference system, when multiple speech languages exist, each conference place has a conference according to the selectedlanguage.

Description

[0001] This application is a divisional application for the application file with the application number 200610063017.7, the application date is September 30, 2006, and the title is "A System and Method for Realizing Multilingual Conference". Applying. technical field [0002] The invention relates to the technical field of communication, in particular to a multipoint control unit and a conference terminal for realizing multilingual conferences. Background technique [0003] 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 attached figure 1 As shown, a video conference generally consists o...
