Based on video conference network system shown in Fig. 3, with reference to the accompanying drawing to the control of video conference provided by the present application
Method processed is described in detail.
It is illustrated in figure 4 the control method detailed process of the first video conference provided herein.
The meeting-place characteristic information in step 400:MCU acquisition target meeting-place.
It is that each of video conference network meeting-place configures meeting-place characteristic information, meeting-place characteristic information is matched in the application
It sets mode to be not construed as limiting in this application, for example, the configuration mode of meeting-place characteristic information can be with are as follows: the institute in video conference network
There is the meeting-place characteristic information in meeting-place to be stored in advance in LIST SERVER, MCU receives SMC by inquiring acquisition to LIST SERVER
Meeting-place characteristic information.
The information category of meeting-place characteristic information can be the classes such as region, department, role, subject under discussion.Where region, that is, meeting-place
Region, such as Guangdong, Beijing, Shanghai etc., the department where participant in department, that is, meeting-place, such as research and development department, market department, training
Instruction portion etc., participant role in video conference, such as governor, the mayor, minister etc. in role, that is, meeting-place, subject under discussion, that is, meeting-place exists
The subject under discussion participated in video conference, such as subject under discussion 1, subject under discussion 2, subject under discussion 3.
Each big class can also include now several small classifications, for example, the regional feature information in some meeting-place is big
Class is Guangdong now, and group is Guangzhou and Shenzhen now.
The information category of the above meeting-place characteristic information is only citing, and the application does not do the information category of meeting-place characteristic information
It is specific to limit.
In practical application, after meeting-place calls membership, MCU actively to meeting-place can issue site list, can also be
It receives and feeds back site list to it after the site list that request meeting-place is sent is requested, the target meeting-place is to request meeting to MCU
The meeting-place of field list, alternatively, MCU actively issues the meeting-place selected when site list.
MCU may obtain the meeting-place characteristic information in target meeting-place by any one in following two mode:
MCU receives the site list request that the target meeting-place is sent, and determines target meeting-place according to the site list
The meeting-place characteristic information carries the meeting-place characteristic information for determining the target meeting-place in site list request
Information category；Or
MCU receives the instruction information that Service Management Center SMC is issued, and determines the target meeting-place according to the instruction information
Meeting-place characteristic information, carry information for determining the meeting-place characteristic information in the target meeting-place in the instruction information
Classification.
If information category is region, region of the meeting-place characteristic information in the target meeting-place obtained i.e. where target meeting-place；
If information category is department, the i.e. corresponding department in target meeting-place, that is, mesh of the meeting-place characteristic information in the target meeting-place obtained
The department where participant in rotating savings field；If information category is role, the meeting-place characteristic information in the target meeting-place obtained is i.e.
The corresponding role in target meeting-place, that is, the role of the participant in target meeting-place；If information category is subject under discussion, the mesh obtained
The subject under discussion that the meeting-place characteristic information of rotating savings field, that is, target meeting place participates in.
Specifically, after target meeting-place calls membership, the instruction information that MCU is issued according to the SMC received selects phase
Answer the meeting-place characteristic information in the target meeting-place of classification.The information for determining target meeting-place characteristic information is carried in the instruction information
Classification.For example, MCU is selected in the characteristic information in target meeting-place if the information category carried in the instruction information is region
Regional information, such as Nanjing.
Another situation, after target meeting-place calls membership, the site list that MCU receives the transmission of target meeting-place is asked
It asks, MCU judges whether carry the information category of characteristic information in the site list request, if so, asking according to site list
The information category of the characteristic information of middle carrying is asked to determine the characteristic information in the target meeting-place, otherwise, the finger that MCU is issued according to SMC
Show that information determines the characteristic information in the target meeting-place.
Wherein, during participant, MCU receives the letter of the carrying characteristic information of target meeting-place transmission at any time
The site list request for ceasing classification requests to redefine the target meeting-place for foundation with the site list being currently received
Characteristic information.
Step 410:MCU is in all meeting-place for participating in video conference, selection and the target meeting-place meeting having the same
The meeting-place of field characteristic information.
Specifically, after the characteristic information for determining target meeting-place, MCU is in all meeting-place for participating in video conference, choosing
Select the meeting-place with target meeting-place meeting-place characteristic information having the same.
If the meeting-place characteristic information is regional information, MCU is in all meeting-place for participating in video conference, selection and institute
The meeting-place that target meeting-place has identical regional information is stated, e.g., region belonging to the target meeting-place is Nanjing, then selection belongs to south
Other meeting-place in capital；
If the meeting-place characteristic information is department's information, MCU is in all meeting-place for participating in video conference, selection and institute
The identical meeting-place of the corresponding department in target meeting-place is stated, e.g., the corresponding department in the target meeting-place is research and development department, then selects corresponding portion
Door is other meeting-place of research and development department
If the meeting-place characteristic information is Role Information, MCU is in all meeting-place for participating in video conference, selection and institute
The identical meeting-place of the corresponding role in target meeting-place is stated, e.g., the corresponding role in the target meeting-place is governor, then selects corresponding role
For other meeting-place of governor；
If belonging to the characteristic information being subject under discussion information, MCU is in all meeting-place for participating in video conference, selection and institute
The meeting-place that target meeting-place participates in identical subject under discussion in video conference is stated, e.g., the subject under discussion that target meeting place participates in is subject under discussion 1,
Then select other meeting-place of participation subject under discussion 1.
Step 420:MCU generates the site list in the meeting-place comprising selecting.
MCU generates site list, the meeting-place for including in the site list based on the meeting-place screened in step 410
With target meeting-place characteristic information having the same, for example, if the meeting-place characteristic information in the target meeting-place obtained in step 400 be ground
Domain information then includes the meeting-place of region identical as target meeting-place in the site list of this step generation.In another example if step 400
The meeting-place characteristic information in the target meeting-place of middle acquisition is department's information, then includes and target meeting in the site list that this step generates
The meeting-place of field same department.
The site list of generation is sent to the target meeting-place by step 430:MCU.
As described in step 410, MCU actively can issue site list to target meeting-place after the membership of target meeting-place,
Site list can be fed back to target meeting-place after the site list request for receiving target meeting-place.
So far, by above-mentioned video conference control method process introduction it is found that MCU issued to target meeting-place be no longer
Site list including whole meeting-place, but according to the characteristic information in target meeting-place, the purposive selection in all meeting-place with
Target meeting-place has the meeting-place of same characteristic features information, generates site list, and the control interface in target meeting-place only shows related meeting
Field list, so that meeting-place control interface is succinct, it is easy to operate, it is easy to check；Also, realize site list in video conference
Classification fraction show, classification fraction video conference in, low level, low rights meeting-place can only receive same level, with weigh
The site list of the meeting-place composition of limit, not can be appreciated that the information in the meeting-place of high-level, high permission, to ensure that in video conference
Middle site management is orderly and the secret in meeting-place is not leaked.
In addition, in the video network architecture of the application, if there are cascade higher level MCU or cascade juniors by MCU
MCU, then in above-mentioned steps 410 or before, MCU is synchronous by passing through between cascade higher level MCU or cascade junior MCU
Site list information, to obtain all meeting-place in video conference.Specifically, after SMC port operation meeting is held, SMC is to MCU
Initial site list is distributed, in general, SMC is to distribute initial site list to MCU according to region, i.e., connects under cascade MCU
The meeting-place connect is the meeting-place of same region.
In the application, if MCU is the meeting-place characteristic information that the instruction information issued by SMC determines target meeting-place, this
A kind of preferable implementation has also been devised in application, specifically:
If the instruction information that MCU is issued according to SMC determines that the meeting-place characteristic information in target meeting-place is regional information, MCU
The synchronous site list information between its cascade higher level MCU or junior MCU can not be had to, directly to the target connecting with MCU
Meeting-place issues initial site list.
In the above-mentioned methods, in the site list that MCU is sent to meeting-place, the meeting-place characteristic information comprising meeting-place.Based on this,
The control method of second of video conference has also been devised in the application.This method comprises:
MCU receives the Conference control instruction for carrying meeting-place characteristic information, and the meeting-place characteristic information is the ground where meeting-place
The subject under discussion that domain, the corresponding department in meeting-place, the corresponding role in meeting-place or meeting place participate in；
MCU determines the target meeting-place with the meeting-place characteristic information in all meeting-place；And to determining each target meeting
Field executes the Conference control and instructs corresponding operation.
Wherein, MCU receives the Conference control instruction for carrying meeting-place characteristic information, comprising:
MCU receives the Conference control instruction for the one meeting-place characteristic information of carrying that Service Management Center SMC is sent；Or MCU connects
The Conference control for receiving the carrying meeting-place characteristic information that chair terminal sends according to the meeting-place characteristic information in each meeting-place instructs.Its
In, MCU receives the Conference control for the carrying meeting-place characteristic information that chair terminal sends according to the meeting-place characteristic information in each meeting-place
Before instruction, MCU sends site list after receiving the site list request of chair terminal's transmission, to chair terminal, described
It include the corresponding meeting-place characteristic information in each meeting-place in site list.
That is, the Conference control instruction for the carrying meeting-place characteristic information that MCU is received may be chair terminal's transmission
, it is also possible to what SMC was sent.Conference control instruction can be to be used to indicate to execute the mute instruction for waiting operations to meeting-place.
For example, in practical applications, there is meeting-place A, meeting-place B, tri- meeting-place meeting-place C under Shenzhen detachment in video conference,
Chair terminal selects Shenzhen detachment in operation interface, control instruction be it is mute, then MCU receives the carrying of chair terminal's transmission
The mute control instruction of this regional information of Shenzhen detachment, for meeting-place A, the meeting-place B, meeting for regional information being Shenzhen detachment
Field these three meeting-place C, execute mute operation.
In another example having meeting-place D, two meeting-place meeting-place E under market department in video conference, SMC is selected in operation interface
Market department, control instruction are that more pictures are arranged, then MCU receives carrying this sector feature information of market department of SMC transmission
The control instruction of more pictures is set, and for the meeting-place D for department's information being market department, it is more to execute setting for two meeting-place meeting-place E
The video pictures group of meeting-place D and meeting-place E is combined into more pictures and is sent to the meeting-place for needing to watch by the operation of picture.
In this manner it is achieved that can control for the meeting-place group that seeks unity of action with a certain special characteristic information, meeting is improved
The convenience of control.
Below for there are the application scenarios of cascade MCU in video conference network, to the above-mentioned video conference of the application
Control method remakes further introduction.
As shown in figure 5, there are two cascade MCU, in this application scene to cascade junior's MCU Xiang Yuqi phase in MCU
Target meeting-place even issues for site list.
Step 501:SMC port operation meeting is held.
In this step or before, SMC can determine the information category of target meeting-place characteristic information, wherein the info class
It is not preset by administrator.
Step 502:SMC sends the request of inquiry meeting-place characteristic information to LIST SERVER.
Step 503:SMC receives the meeting-place characteristic information in all meeting-place of video conference that LIST SERVER returns.
Wherein, step 501 can be after the step 503.
Step 504: MCU at different levels and meeting-place call membership.
Step 505:SMC superior MCU and junior MCU send initial site list respectively.
The meeting-place for including in the initial site list is generally the meeting-place that SMC is distributed according to the region MCU.And it is described initial
It include the meeting-place characteristic information in each meeting-place in site list.
Optionally, in this step, SMC can also superior MCU and junior MCU send select in step 501 respectively
Obtain the information category of target meeting-place characteristic information.
Step 506: it is synchronous that site list is carried out between cascade junior MCU and higher level MCU.
After synchronization, each MCU obtains all meeting-place.For example, include 30 meeting-place in this video conference network,
It include 20 meeting-place, the initial meeting of junior MCU in the initial site list of higher level MCU in original allocation according to region difference
It include 10 meeting-place in the list of field, then after synchronizing site list, cascade higher level MCU and junior MCU obtain this 30
The meeting-place information in meeting-place.
If in step 505, SMC superior MCU and junior MCU sends the acquisition target selected in step 501 respectively
The information category of meeting-place characteristic information, then the subsequent step 508 that can directly execute is to step 509.
If in step 501, the information category of the non-selected meeting-place characteristic information for obtaining target meeting-place of SMC, or, in step
In 505, SMC non-superior MCU and junior MCU send the meeting-place characteristic information in the acquisition target meeting-place selected in step 501
Information category, then arrive step 509 by after step 507, executing step 508.
Step 507: target meeting-place sends site list request to junior MCU, and it is special to carry meeting-place in site list request
The information category of reference breath.
Step 508: junior MCU selects to have with target meeting-place in all meeting-place according to the characteristic information in target meeting-place
The meeting-place of same characteristic features information generates site list；
Step 509: junior MCU sends the site list of generation to target meeting-place.
In addition to the target meeting-place being connect shown in Fig. 5 with junior MCU, connect with junior MCU there are also other targets
Meeting-place, alternatively, also having other target meeting-place with what higher level MCU was directly connected to.Junior MCU is respectively to each coupled mesh
Rotating savings field sends corresponding site list, and equally, higher level MCU also sends to each coupled target meeting-place corresponding respectively
Site list.In this way, each meeting-place can obtain corresponding site list, the meeting-place that each meeting-place receives is arranged
Table may be identical or different.
The control method of the third video conference has also been devised in the application, as shown in fig.6, detailed process is as follows.
Step 601:SMC determines the corresponding relationship of meeting subject under discussion and period, and participate in the meeting-place of each meeting subject under discussion
Information.
Specifically, according to conference content difference, video conference can be divided into different meeting subjects under discussion, and different time sections are to responding
