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

Abstract

The present invention relates to the technical field of communications and provides a method, a device and a cascade conference system for processing cascade conference sites in a cascade conference. The method for processing cascade conference sites in a cascade conference comprises: receiving a media code stream sent by an ordinary conference site; decoding the media code stream to obtain media data of the ordinary conference site; selecting media data from candidate media data to perform audio mixing, so as to obtain media data of a cascade conference site that needs to be sent, wherein the candidate media data at least comprises the media data of the ordinary conference site; and directly sending to a first cascade conference site media data of the cascade conference site that needs to be sent. By using the present invention, the number of encodings and decodings of sound of an ordinary conference site connected to one MCU heard by an ordinary conference site connected to another MCU in the cascade conference site is reduced, thereby reducing the damage to audio quality and improving the user experience of participants.

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
