本発明は、遠隔の多地点各々に設けた各会議室相互間に
おいて、音声および映像による会議を行なうテレビ会議
システムに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a television conference system for conducting audio and video conferences between conference rooms provided at multiple remote locations.
か＼るテレと会議システムにおいては、各会議室相互間
を通信回線により接続すると共に、会議の開始および終
了時刻を予約情報として記憶しておき、この開始時刻に
相互間の回線構成を行なう一方、終了時刻となれば相互
間の回線構成を解除するものとなっている。In such a teleconference system, each conference room is connected to each other by a communication line, and the start and end times of the conference are stored as reservation information, and the line configuration between the conference rooms is performed at this start time. , when the end time is reached, the line configuration between them is canceled.
したがって、事前に会議終了時刻の延長更新を記憶装置
に対して行なわない限シ、終了時刻となれば強制的に回
線構成が解除され、会議が継続中であっても、これが中
断する欠点を生じている。Therefore, unless the extension of the conference end time is updated to the storage device in advance, the line configuration will be forcibly canceled when the end time is reached, and even if the conference is still in progress, it will be interrupted. ing.
前述の課題を解決するため、本発明はつぎの手段により
構成するものとなっている。In order to solve the above-mentioned problems, the present invention is configured by the following means.
すなわち、上述のテレビ会議システムにおいて、各会議

の開始および終了時刻を予約情報として記憶する記憶装
置と、回線切替装置を介して各会議室の使用状況を検出
する検出器と、使用中の各会議室に対し回線切替装置を
介して会議の延長可否を示すメツセージを送出するメツ
セージ発生器と、記憶装置の予約情報および検出器の検
出々力に応じて現行会議の延長可否を判断し、この判断
にしたがい回線切替装置およびメツセージ発生器を制御
する制御装置とを備えたものである。That is, in the above-mentioned video conference system, there is a line switching device that connects the communication lines between each conference room, a storage device that stores the start and end times of the conference as reservation information, and a line switching device that connects the communication lines between each conference room. a detector that detects the usage status of the conference room, a message generator that sends a message to each conference room in use to indicate whether the conference can be extended via a line switching device, and reservation information of the storage device and detection of the detector. The system is equipped with a control device that determines whether or not a current meeting can be extended depending on the current situation, and controls a line switching device and a message generator in accordance with this determination.
したがって、現行会議が予約情報の終了時刻となっても
継続する場合、検出器の検出々力が示す各会議室の使用

能であれば、この旨のメツセージが各会議室へ送出され
ると共に、各会議室相互間の回線構成が保持される。Therefore, if the current conference continues even after the end time of the reservation information, the next reservation information will be updated according to the in-use information of each conference room indicated by the detection power of the detector and the reservation information of the storage device. The control device determines whether extension is possible due to the association, and if possible, a message to that effect is sent to each conference room, and the line configuration between each conference room is maintained.
以下、実施例を示すブロック図によって本発明の詳細な
説明する。Hereinafter, the present invention will be described in detail with reference to block diagrams showing embodiments.
同図においては、遠隔の多地点各々に設けた複数の会議

記憶装置（以下、ＭＶ）５が付属し、これにより複数の
会議各々毎の開始および終了時刻を予約情報として記憶
するものとなっている。In the figure, a plurality of conference rooms (hereinafter referred to as MRs) 11 to 1n provided at each remote multipoint are communication lines (hereinafter referred to as lines).
2a to 2n, sw3 is accommodated in the line switching device (hereinafter referred to as 5W) 3, and the control device (hereinafter referred to as CNT) 4
The connection status is controlled by the CNT 4, and a storage device (hereinafter referred to as MV) 5 is attached to the CNT 4, which stores the start and end times of each of a plurality of conferences as reservation information.
また、ＳＷａを介し、各ＭＲ１ａ〜１ｎに設けた端末装
置の電源人・切をパイロット信号等により検出する検出
器（以下、ＤＥＴ）６、および、同様にＳＷａを介し、
各ＭＲ１ａ〜１ｎの端末装置に対して現行会議の延長可

ＤＥＴ６の検出々力がＣＮＴ４へ与えられていると共に
、ＭＳＧ７はＣＮＴ ４により制御されるものとなって
いる。Also, via SWa, a detector (hereinafter referred to as DET) 6 that detects whether the power supply of the terminal device installed in each MR 1a to 1n is switched on or off using a pilot signal or the like, and similarly via SWa,
A message generator (hereinafter referred to as MSG) 7 is provided which sends a message indicating whether or not the current conference can be extended to the terminal device of each MR 1a to 1n in the form of a text or voice signal.
The detection power of DET6 is given to CNT4, and MSG7 is controlled by CNT4.

々力としてＣＮＴ４へ与えているため、この検出々力お
よびＭＶ５のつぎの予約情報に応じて現行会議の適長可
否をＣＮＴ４が判断し、つぎの予約情報の開始時刻まで
に余裕があれば、ＣＮＴ４がＳＷａを制御して現状の接
続状態を保持させると共に、ＭＳＧ７を制御して現行会
議の延長可能を示すメツセージを送出させる。In this case, for example, lines 2a, 2 of MRlm, 1b
b is connected by sw3 under the control of CNT 4, and M
If a conference is in progress between MRlm and 1b, and the end time according to the reservation information of MV5 is just before the end time, DET6 will connect to MRlm and 1b.
Since the power supply persons m and 1b are detected and the in-use information is given to CNT4 as detection power, CNT4 determines whether the current meeting is suitable for the length according to this detection power and the next reservation information of MV5. If there is a margin before the start time of the next reservation information, the CNT 4 controls the SWa to maintain the current connection state, and also controls the MSG 7 to send a message indicating that the current conference can be extended.
したがって、ＭＲｌｍ、１ｂにおいては、現行会議の延
長が許容されたことの報知がなされ、これに応じて会議
を続行することができる。Therefore, MRlm, 1b is notified that the extension of the current conference is allowed, and can continue the conference accordingly.
ま九、ＭＲｌｍ、１ｂ中のいずれかｙ電源を切としてい
れば、これに応じた検出々力をＤＥＴ６が送出するため
、ＣＮＴ４Ｆｉ会議終了と判断し、ＳＷａを制御して接
続状態を解除する。If any one of M, MRlm, and 1b is powered off, the DET6 will send out a detection force corresponding to this, so it will judge that the CNT4Fi conference is over and control SWa to release the connection state.
これに対し、ＭＲ１” Ｎ ’ ｂが使用中であっても
、つぎの予約情報との関連上延長不可能とＣＮＴ４が判
断すると、現行会議の終了時刻数分前にＭＳＧ７を制御
し、会議延長不可能を示すメツセージを送出したうえ、
予定の終了時刻にＳＷａを制御して回線２ｍ、２ｂ相互
間の接続を解除する。On the other hand, even if MR1"N'b is in use, if CNT4 determines that it cannot be extended due to the relationship with the next reservation information, it will control MSG7 several minutes before the end of the current conference and extend the conference. In addition to sending a message of impossibility,
At the scheduled end time, SWa is controlled to disconnect the lines 2m and 2b.
