Description
Technical field
The present invention relates to the video conferencing technology field, be specifically related to a kind of method, multipoint control unit (MCU, Multi-Point Control Unit) and chairman's terminal of in video conference, transferring the meeting-place.
Background technology
Video conferencing system realizes virtual meeting by the network communications technology, and the user who disperses on the geography is accumulated in a place, by multiple mode exchange of information such as image, sound, carries out collaborative work.Space length has been shortened in video conference to the full extent, has made things convenient between the cooperation member in real time, has exchanged intuitively.
In video conference, the Conference Room that participates in video conference is called as the meeting-place.As a rule, corresponding video terminal in meeting-place.In video conference, there is a Chair site usually, corresponding to chairman's terminal.In the video conference, the broadcast of meeting field picture has two kinds usually, a kind of is broadcast playback, be that MCU selects a meeting field picture to be transmitted to all terminals (meeting-place) in the meeting, make all participant meeting-place all watch this meeting field picture, this meeting-place is current to be exactly " being broadcasted the meeting-place " (or " person of being broadcasted "), common whenever all exist " being broadcasted the meeting-place " in meeting; Another kind is that clean culture is play, and normally MCU is transmitted to another meeting-place with a meeting field picture, makes described another meeting-place see this meeting field picture.It is the requirement of watching of single-point that clean culture is play, be generally used for Chair site (terminal) watch with video conference in other-end meeting field picture inequality.
Generally, the whole video meeting is carried out according to predefined flow process, all watches a certain specific meeting field picture in all meeting-place of synchronization, listens to the sound in this meeting-place.The flow process of whole meeting is operated control by the administrative staff or the Chair site of MCU side, according to agenda or current needs, switches different meeting-place and broadcasts in meeting.
In the prior art, in the process of video conference, the basic operation of broadcast playback may further comprise the steps:
A, in chairman's terminal during as the meeting effector, chairman's terminal is preserved the information in all participant meeting-place to MCU request participant site list in this tabulation;
B, open above-mentioned site list, show all participant meeting-place;
C, in above-mentioned site list, find the meeting-place that to broadcast;
D, the meeting field information that will need to broadcast send to MCU;
E, MCU will understand field picture and be transmitted to meeting-place all in the meeting.
The aforesaid operations flow process is to be that example describes with chairman's terminal as the meeting effector, and at MCU during as the meeting effector, the flow process of broadcast playback only needs above-mentioned b, c, three steps of e.
In video conference, generally all be the meeting-place of the several main speeches of frequent broadcasting, the meeting-place at chairman/host place or need in conference, participate in speech and the meeting-place of discussion for example.Other participant meeting-place generally speaking only need be when meeting begins and other meeting-place say hello, audit the role and carry out being in substantially in the process in meeting, do not need to be watched, thereby needn't broadcast yet by other meeting-place.
For example, suppose when holding national congress, corresponding meeting-place, each province, Chair site is meeting-place, Beijing, whole session discussing northeast China's economic development problem, conference process should be usually:
Broadcasting meeting-place, Beijing;
Broadcasting meeting-place, Heilungkiang;
Broadcasting meeting-place, Beijing;
Broadcasting meeting-place, Jilin;
Broadcasting meeting-place, Beijing;
Broadcasting meeting-place, Liaoning;
Broadcasting meeting-place, Heilungkiang;
Broadcasting meeting-place, Jilin;
Broadcasting meeting-place, Liaoning;
……
In conference process, can broadcast repeatedly with the relevant meeting-place such as Heilungkiang, Jilin and Liaoning of the Northeast in chairman (Beijing) meeting-place, makes a speech, and other regional meeting-place seldom need to be broadcasted in the meeting.
And for example, suppose to hold the long-range debate of national universities, pros distinguish that the friend distinguishes the friend in another school (meeting-place) a school (meeting-place), negative side, and the judge is in a place (meeting-place), and other each schools are the spectators meeting-place, then in whole meeting, the meeting process normally:
Broadcasting judge meeting-place;
Broadcast square meeting-place;
Broadcasting negative side meeting-place;
Broadcast square meeting-place;
Broadcasting negative side meeting-place;
Broadcast square meeting-place;
Broadcasting negative side meeting-place;
In this case, the meeting-place that is broadcasted in whole meeting nearly all is " pros " and " negative side " two meeting-place, and other meeting-place can be broadcasted hardly.
As can be seen, in the above-mentioned broadcast site scheme of prior art, if the participant meeting number in the video conference is more, the participant site list is longer, so, and in MCU side or chairman's end side, when if the user wants to switch current meeting-place of broadcasting, then need to thumb one by one in site list and seek meeting-place, target meeting-place (to be broadcast), the operation of transferring the meeting-place must expend time in longer, and the meeting-place switching efficiency is low; Site list is longer simultaneously, and the user chooses wrong meeting-place through regular meeting when choosing certain meeting-place with mouse, cause the target meeting-place to transfer mistake, influences normally carrying out of video conference.
Summary of the invention

Embodiment
According to the analysis of inventor to most of video conferences, discovery is in a video conference, though participant meeting number is a lot, may reach tens of to hundreds of, but in meeting, need meeting-place (Fa Yan the meeting-place in other words) quantity broadcasted in fact and few, and often be that some meeting-place is broadcasted repeatedly, promptly current meeting-place to be broadcast often is the meeting-place of having broadcasted on this meeting front.
The present invention is directed to the higher characteristics of probability that the meeting-place that once was broadcasted is in history broadcasted once more in conference process, the meeting field information in the meeting-place of once broadcasting in history is kept at first site list, and then when transferring broadcast site, can in this tabulation, search the meeting field information in meeting-place to be broadcast earlier, to avoid the difficulty in meeting-place to be broadcast, location in all long participant site lists of length.Below in conjunction with accompanying drawing, the invention will be further described by specific embodiment.
＜embodiment 1 〉
As scheme shown in the l, the described method of in video conference, transferring the meeting-place of present embodiment, MCU transfers to be broadcast meeting-place by user (administrative staff) at the MCU place as the meeting effector, and this method may further comprise the steps:
Operating instruction for above-mentioned memory space is as follows:
A) video conference is initial, does not have nearest meeting-place of broadcasting in the meeting, and this moment, memory space was empty;
B) in the video conference process, when current broadcast site switches to the B meeting-place by the A meeting-place, then with the meeting-place information stores in described A meeting-place in described memory space, and be positioned at the tail of the queue of described storage queue, simultaneously, the meeting field information with previous each meeting-place of preserving in the memory space all moves one to the head of the queue of storage queue;
C) in the video conference process, when current broadcast site switches to the B meeting-place by the A meeting-place, if storage queue is full, for example, the memory space setting only can be stored the meeting field information in 5 meeting-place, and has currently preserved 5 meeting field information, at this moment, still according to b) in mode preserve, the meeting field information with head of the queue abandons simultaneously;
D) in the video conference process, when current broadcast site switches to the B meeting-place by the A meeting-place, if in the meeting field information storage queue Already in (memory space) in described A meeting-place, two kinds of preserving types then can be arranged: a kind of is behind the meeting-place information deletion with the A meeting-place in the storage queue, according to b) in mode preserve the meeting field information in A meeting-place again; Another kind is directly according to b) in mode preserve, like this, in storage queue, may have the meeting field information in identical meeting-place;
E) in the video conference process, when MCU withdraws from video conference in certain meeting-place in detecting storage queue (memory space), the meeting field information of this meeting-place correspondence of deletion in storage queue, and rearrangement storage queue, here, detect certain meeting-place withdraw from video conference concrete can be: MCU receives the defection message of sending in this meeting-place, or MCU to detect the TCP link in this meeting-place overtime, or this meeting-place is forced to leave video conference;
F) when all meeting-place in the video conference not online (not having the meeting-place in the meeting), when perhaps meeting is not held, memory space is emptied.
The above-mentioned method of transferring the meeting-place by preserving the meeting field information in the meeting-place of once broadcasting in history, forms first site list, thereby the higher meeting-place of broadcasting probability in the video conference is extracted; When transferring the meeting-place, at first search this first site list, search second site list of preserving all meeting field information again.Because the probability that meeting-place to be broadcast is present in first site list is higher, and the meeting-place of preserving in first site list is more a lot of than lacking in second site list, thereby, present embodiment can avoid the user to search and confirm the operation in meeting-place to be broadcast in the second long site list, reduces the meeting-place and transfers required time, simultaneously, because the meeting-place number in first site list is less, the user is easier to choose meeting-place to be broadcast, thereby, reduce the target meeting-place and transferred wrong probability of happening.
In the above-mentioned method of transferring the meeting-place, be the operation interface that MCU provides one first site list, on this operation interface, meeting field information listed in first site list directly searched and chosen by the user.In the present embodiment, can also provide some more direct operation interfaces respectively at nearest several meeting-place of broadcasting at the MCU place, for example, in described first site list,, preserve the meeting field information in the meeting-place of the predetermined quantity of broadcasting recently successively further according to the sequencing of each meeting-place broadcasting; And, a button is provided on the operation interface of MCU, this button is corresponding to the meeting field information (being the meeting field information in a nearest meeting-place that is broadcasted) in last meeting-place of preserving in first site list, like this, if the user wants to transfer last of current time and was broadcasted the meeting-place, then can directly click this button; Like this, MCU is after this button is clicked, receive the clicking trigger message of this button, include the positional information (herein positional information be the meeting field information in last meeting-place in first site list) of meeting field information in first site list in meeting-place to be broadcast in this message, and then, MCU is according to this positional information, can from first site list, obtain the meeting field information in meeting-place to be broadcast, and determine meeting-place to be broadcast according to the meeting field information in meeting-place to be broadcast, be the B meeting-place, and then broadcast operation is carried out in this B meeting-place.This mode can further be simplified the operation of in the conference process meeting-place of just having broadcasted being dispatched once more broadcasting.Similarly, can also corresponding button be set for other meeting-place in first site list, with provide more simply to the user, function is transferred in the meeting-place efficiently.
