Processing method and device of cascade conference place in cascade conference and cascade conference system

Abstract

The invention relates to the technical field of communication and discloses a processing method and a device of a cascade conference place in a cascade conference and a cascade conference system. The processing method of the cascade conference place in the cascade conference comprises receiving media code stream sent by an ordinary conference place, decoding the media code stream to obtain ordinary conference place media data, selecting the media data from the alternative media data for sound mixing to obtain the cascade conference place media data which need to be sent, and directly sending the cascade conference place media data which need to be sent to a first cascade conference place, wherein the alternative media data at least comprise the ordinary conference place media data. By the adoption of the processing method, the times of coding and decoding of sound of an ordinary conference place connected to a micro-programmed control unit (MCU) being heard by another ordinary conference place connected to the MCU in the cascade conference place is decreased, accordingly damage to sound quality is reduced, and user experience of the participants is enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a processing method and device for a cascaded conference site in a cascaded conference, and a cascaded conference system. Background technique [0002] In a general audio / video conference, a conference is usually held between common sites under a multipoint control unit (MCU: MultiController Unit), that is, the common sites in the conference are all connected to the same MCU. However, as the conference capacity increases or the networking becomes more and more complex, it is necessary to hold a cascaded conference, that is, not only the common conference site under each MCU joins the conference, but also multiple MCUs connect multiple MCUs through the cascaded conference site. Meetings are connected into one meeting, so that the purpose of meeting together in common venues of multiple MCUs is achieved. For example, if a system needs to hold a national conference, it has M...

Problems solved by technology

[0010] It can be seen from the above that if a common site connected to one MCU in a cascaded site wants to hear the sound of an ordinary site connected to another MCU, the sound needs to be coded and decoded by multiple MCUs, and each codec will damage the sound. Sound quality, so the more cascading stages in the cascaded venue, the more the sound quality will be damaged. For example, the data of T1 needs to be coded and decoded by MCU1, MCU2 and MCU3 respectively before being heard by T9, and the sound quality will be greatly reduced. Attendee User Experience
