Description
発明の技術分野
本発明は、一般に会議システムに関し、より詳細には多地点音声及び/またはマルチメディア会議のための制御ユニットに関する。
従来技術の説明
現在の音声会議あるいはビデオ会議では、参加者は1つの会議に参加できる実体である(すなわち、参加者は1つの会議で発言及び/または聴取を行うことができる)。しかしながら、しばしば参加者は1つのグループに対し発言し、それと同じ時間帯に関連した会議あるいは関連のない会議の他のグループの話を聞く必要があるかもしれない。
[発明の概要]
本発明は、各参加者が複数の会議に参加することを可能にする音声またはマルチメディア会議の制御システム及び方法を提供する。本発明は、MCUの音声セクション及び管理制御システム(MCS)セクションにおいて動作しうる。
[実施例の説明]
同一の番号により同一の構成要素が表されている図面を参照し、本発明の実施例が説明される。
またはそれらを組み合わせたものとして構成されうるということは当業者には理解されるであろう。もしMCS1170がソフトウェアである場合、MCS1170は関連するMCUのホストコンピュータ内に設置されていてもよい。あるいは、MCS1170がハードウェアである場合、MCS1170はMCU内の追加ユニットとして構成されてもよい。
