Description

Conference control method, control device and management device

This application is submitted to the Chinese Patent Office on January 22, 2009, the application number is 200910006040.6, the invention name is "a control method, device and system for a conference terminal" and submitted to the Chinese Patent Office on February 20, 2009, the application number The priority of the Chinese Patent Application No. 200910037301.0, entitled "A Conference Control Method, Conference Control Device, and Conference System", the entire contents of which is incorporated herein by reference.

Technical field

The present invention relates to the field of communications, and in particular, to a conference control method, a control device, and a management device. Background technique

Video conferencing realizes virtual conferences through network communication technology, and gathers geographically dispersed users in one place, and exchanges information through various methods such as images and sounds to carry out collaborative work. Video conferencing shortens the spatial distance to the greatest extent, facilitating real-time and intuitive communication between collaborative members. The implementation of the MCU (Multipoint Control Unit) provides effective scheduling control for video conferencing. 1 is a video conference implemented by a cascaded MCU in the prior art, in which terminals T1 l, Τ12, Τ13, Τ14, Τ21, Τ22, Τ23 join a conference, and the conference is composed of two cascaded MCUs: MCU1 and MCU2 Composition, after the conference list is synchronized between MCU1 and MCU2, the conference lists on MCU1 and MCU2 are Tl l, Τ12, Τ13, Τ14, Τ21, Τ22, Τ23, and finally MCU1 and MCU2 forward the synchronized conference list to The terminal at the level.

However, the inventors have found in the research that in the cascaded conference system in the prior art, the conference list received by each terminal includes all terminals in the current conference system, and therefore, each terminal can Any terminal including its own in the control system. Moreover, when each terminal applies to become the chairman, the same conference control operations can be performed, for example, broadcast terminal, selective viewing, application for speaking, naming speech, setting voice switching, free discussion, sending auxiliary stream, setting multi-picture and broadcasting. Multi-screen and other operations. Each non-chairperson's terminal also has the same permissions and can choose to view any one of the venues.

Similarly, when all the terminals have the same rights and cannot be treated differently, if the user has special requirements, such as some sites cannot apply for the chairperson, some sites cannot deprive the auxiliary stream tokens, etc., and the user needs to be given. Special customized versions result in many versions and high R&D costs. In addition, in departments such as the military system that require external secrecy, there are high requirements for confidentiality and information security. When the terminal of the department seeking external secrecy enters the conference system, if other terminals can perform conference control operations on the terminal that requires confidentiality, the confidential information will be leaked, which affects the confidentiality and security of the terminal.

detailed description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings.

In the embodiment of the present invention, a priority policy is adopted for conference control, and a special conference system version is not required to meet different conference control requirements, thereby implementing flexible control of permissions in the conference, and Effectively reduce the research and development costs of conference control. Embodiment 1

FIG. 2 is a schematic flowchart of a conference control method according to Embodiment 1 of the present invention, including: 200. Set a priority level of the conference control operation request according to a conference control operation request sent by a terminal and a preset conference control policy.

The conference control operation request sent by the terminal in the embodiment of the present invention may include a priority level preset by the terminal for the conference control operation request, where the preset priority level may be the priority level of the terminal itself. The preset priority level of the control operation request may also be a priority level that the terminal separately sets for the conference control operation request according to the needs of the terminal. In a preferred embodiment, the terminal's own priority level is typically set to the preset priority level of the conference control request that it sends.

It should be noted that the priority level of the terminal may be set by the terminal itself, or may be set by the conference control terminal or the conference chairperson. The conference console includes an MCU or gateway and other systems that can be set up or controlled by the conference.

The conference control policy includes a specific processing manner for setting a priority level of a conference control operation request sent by different terminals according to user requirements.

For example, when the conference control operation request includes a preset conference control operation request priority level, the conference control policy includes but is not limited to:

Setting a priority level of the conference control operation request to a preset conference control operation priority level carried in the conference operation request;

For example, the video conference includes terminal A and terminal B, and the control terminal is an MCU. The preset control policy is: setting the priority level of the conference control operation request sent by the terminal to the preset conference operation operation priority level carried in the conference operation request.

The A terminal sends a conference control operation request A1 with a preset priority level of 15 to the MCU, and the B terminal sends a conference control operation request B1 with a preset priority level of 10 to the MCU, and the MCU sets according to the preset conference control policy. The priority level of the conference operation request A1 is 15, and the priority level of the conference operation request B1 is set to 10.

Or setting a priority level of the conference control operation request to a priority level of the terminal that sends the conference control request message; For example, the video conference includes terminal A and terminal B, the control terminal is an MCU, the priority of the A terminal is 20, and the priority of the B terminal is 30. The pre-set conference control policy is: setting the priority level of the conference control operation request sent by the terminal to the priority level of the terminal that sends the conference control request message.

The A terminal sends a conference control operation request A1 with a preset priority level of 15 to the MCU, and the B terminal sends a conference control operation request B1 with a preset priority level of 10 to the MCU, and the MCU sets according to the preset conference control policy. The priority level of the conference operation request A1 is 20, and the priority level of the conference operation request B1 is set to 30.

Or setting the priority level of the conference control operation request to the default priority level of the control terminal; for example, the video conference includes the terminal A and the terminal B, the control terminal is the MCU, the priority of the A terminal is 20, and the priority of the B terminal is For 30, the MCU defaults to a priority of 10. The pre-set conference control policy is to set the priority level of the conference control operation request sent by the terminal to the default priority level of the console.

The A terminal sends a conference control operation request A1 with a preset priority level of 15 to the MCU, and the B terminal sends a conference control operation request B1 with a preset priority level of 20 to the MCU, and the MCU sets according to the preset conference control policy. The priority level of the conference operation request A1 is 10, and the priority level of the conference operation request B1 is set to 10.

Or set the priority level of the conference control operation request to the priority level specified by the conference chairperson. For example, the video conference includes terminal A and terminal B, the control terminal is an MCU, the priority of the A terminal is 20, and the priority of the B terminal is 30. The preset conference control policy is: Set the priority level of the conference control operation request sent by the terminal to the priority level specified by the conference chairperson.

The A terminal sends the conference control operation request A1 with the preset priority level of 15 to the MCU, and the conference chairperson assigns the priority level of the A1 to 30, the MCU sets the priority level of the conference control operation request A1 according to the preset conference control policy. Is 30.

For example, when the conference control operation request does not include a preset conference operation request priority level, the conference control policy may include:

Setting a priority level of the conference control operation request to a priority level of the terminal that sends the conference control request message;

Or setting the priority level of the conference control operation request to the default priority level of the control terminal; or setting the priority level of the conference operation operation request to the priority level specified by the conference chairperson. For example, the video conference includes the terminal A and the terminal B, the control terminal is the MCU, the priority of the A terminal is 20, the priority of the B terminal is 30, and the default priority of the MCU is 10. The pre-set conference control policy is: When receiving the conference control operation request sent by the terminal A, the MCU sets the priority level of the conference control operation request sent by the terminal A to the default priority level of the MCU; and receives the conference control operation sent by the terminal B. When requesting, the priority level of the conference control operation request sent by the terminal B is set to the priority level of the terminal B itself.

The A terminal sends the conference control operation request A1 with the preset priority level of 15 to the MCU, and the B terminal sends the conference control operation request B1 that does not include the preset priority level to the MCU, and the MCU sets the conference according to the preset conference control policy. The priority of the control operation request A1 is 10, and the priority level of the conference operation request B1 is set to 30.

201. Determine, according to the priority level of the conference control operation request and the preset priority level policy table, whether to perform the conference control operation corresponding to the conference control operation request.

The priority level policy table contains preset minimum priority information required to perform various operations. It should be noted that the conference control operation in the embodiment of the present invention includes not only the standard conference control operation in the H245 protocol, but also all related operations in the conference. FIG. 3 is a schematic flowchart of a conference control method according to a first embodiment of the present invention, including: 300. A conference control policy and a priority policy table are configured.

In the embodiment of the present invention, the configuration control policy and the priority policy table are only executed when the conference is initialized. It should be noted that, in other embodiments, the conference control policy and the priority policy table may be dynamically configured according to requirements. For example, the conference chairperson finds that the conference control authority of a terminal is set too high or too low, and the chairperson may have the right authority. Its priority is adjusted appropriately.

For example, assume a cascaded conference as shown in Figure 1, including the consoles MCU1 and MCU2. The terminals Ti l , T12, T13 , T14 are scheduled on the MCU 1 , and the terminals T21 , Τ 22 , Τ 23 are scheduled to the MCU 2 . The preset conference control policy is: when the conference control operation request sent by the terminal includes a preset conference control operation request priority level, setting the priority level of the conference control operation request to the preset conference control operation The request priority level is set. When the conference control operation request sent by the terminal does not include the preset conference control operation request priority level, the priority level of the conference control operation request is set to the priority level defined by the MCU for the terminal. Let each terminal set its own priority (Ti l : 20; T12: 40; T13: 30; T14: 20; T21: 60; T22: 40; T23: 10), assuming that the MCU is given priority when defining the terminal. Grade (Ti l : 30; T12: 20; T13 : 40; T14: 30; T21 : 50; T22: 50; T23 : 20 ), where, the larger the value, the higher the priority (note that, In other embodiments, the priority level may be expressed in other forms, and the priority level may also be set according to requirements. For example, when the priority is numerical, the lower the value, the higher the priority. . Set the priority policy table configured on the MCU as shown in Table 1:

Table 1

301. Receive a conference control operation request sent by the terminal.

The conference control operation request includes or does not include a preset priority level of the conference operation request. In a preferred embodiment, the conference control operation request carries a preset priority level, wherein the priority level of the terminal is used as a preset priority level of the conference operation request sent by the terminal.

When the conference control operation request carries the preset priority information, it can be used but is not limited to the following:

1. Carry the priority value after the conference control operation, that is, change the following NULL to a specific value. The conference control without setting the priority may not be modified.

ConferenceRequest : :=CHOICE terminalListRequest NULL.

makeMeChair NULL,

cancelMakeMeChair NULL,

dropTerminal TerminalLabel,

2: Carry the conference control message and priority value in the NonStandardMessage message.

NonStandardMessage is a conference control message that is extended in the nonstandard field of the H.245 message in the same way as the standard H.245 conference control message. Such as:

remoteSpeakerOffRequest TerminalSelect - extended request message

TerminalSelect :: =CHIOCE

{

allTerminals NULL, -- allTerminals All the sites on the MCU, NULL value can be used to fill in the specific priority value

terminalsOnMCU SEQUENCE SIZE(1..192) OF

McuTerminalLabels

Some sites on some MCUs }

3: Expand in the Ido conference control protocol and add a priority field to the conference control command. For example, 0x12b sets the voice control switching result.

+0 B Set voice control switching result

0: success, 1 : failure

[failure]

+1 B failure reason

0: The requesting terminal is not the chairman terminal.

OxFF: Other reasons

+2 W priority value Add 2 bytes after the original signaling to fill in the priority value.

302. Set a priority level of the conference operation request according to the conference control operation request and a preset conference control policy.

For example, the terminal T11 initiates a conference control operation request of the viewing site of the T22, and the preset conference control operation priority level 20 is carried in the conference site control operation request, and the MCU finally sets according to the preset conference control policy. The priority level of the conference control operation request by the terminal T11 to view the viewing site of T22 is 20.

303. Acquire, from the priority level policy table, minimum priority information required to perform a conference control operation corresponding to the conference control operation request.

For example: T11 initiates viewing T22 to watch the conference site's conference control operation request, MCU from the above table

The minimum priority required to query the conference site for viewing the site is 20.

304. Determine whether the priority level of the conference control operation request reaches the lowest priority level required to perform the operation operation corresponding to the conference operation operation request, and if the determination is yes, execute the conference control operation corresponding to the conference control operation request, If the determination is no, the conference control operation request sent by the terminal is rejected.

For example, the priority level of the conference control operation requesting the T11 to view the T22 is 20. The MCU performs the conference control operation of the T11 viewing T22.

305. When responding to two or more conference control operations and/or the same type of conference control operation request for the same resource, select the conference control operation corresponding to the conference operation request with the highest priority. For example, when Ti1 and T12 simultaneously initiate a conference control operation request to view the T22 viewing site, the conference control operation request of the viewing site sent by T11 does not carry a preset priority level, and the conference control operation request of the viewing site sent by T22 is performed. The preset priority level 40 is carried, and the MCU receives the conference control operation request sent by the two terminals, and the priority of the conference control operation sent according to the conference control policy setting T11 is 30, and the T12 sends the conference. The priority of the control operation request is 40, which is the lowest priority level for watching the conference control operation. It is assumed that the MCU1 can only view one site on the MCU2, because the priority level 30 of the conference operation request sent by the T11 is smaller than the T12 transmission. The priority level of the operation request is 40, so the conference control operation request of T22 initiated by T12 is executed, and the conference operation request initiated by T11 is rejected.

306, when the resource required for the conference operation request of the response is occupied by another terminal, determining whether the priority level of the conference control operation request is higher than a priority level of the other terminal, and if yes, depriving the other terminal The resource and execute the conference control operation corresponding to the conference control request.

For example, the T12 initiates the operation of the T22 and succeeds. The T11 re-initiates the operation of the T21. The MCU finally sets the priority of the T12 to 40, and the priority of the T11 initiated control operation request to view the site T21 is 30. Assume that the MCU1 can only view one site on the MCU2. The priority of the T12 is greater than the priority of the conference control request of the site T21 sent by the T11, and the T12 occupies the cascading resource.

Or, the terminal T11 initiates the operation of viewing the T21 and succeeds, the T12 re-initiates the conference control operation request to view the T22, the MCU finally sets the priority level of the T11 to 30, and the priority of the conference control request of the T12 to initiate the viewing of the conference site T22 is 40. The T12 may deprive the T11 to view the cascading resources of the T21, because the priority level of the conference control operation request of the T12 initiating the viewing site T22 is greater than the priority level of the T11.

307, when the control operation request corresponding to the operation object is a terminal, determining whether the priority level of the conference control operation request is higher than a priority level of the terminal, and if yes, performing a conference control operation corresponding to the conference control operation request .

For example, the priority of the terminal T22 is 40, and the terminal T11 initiates a conference control operation request for viewing a viewing site of the T22, and the preset conference control operation priority level 20 is carried in the conference site control operation request, according to the foregoing preset. The conference control policy, the MCU finally sets the priority level of the conference control request of the terminal T11 to view the viewing site of the T22 to be 20. Due to the T11 initiated viewing of the venue T22 The priority of the conference control request is not T22 high, so the operation of T11 viewing site T22 will be rejected. It should be noted that there is no necessary sequential relationship between steps 305, 306, and 307.

Meanwhile, in other embodiments, the priority of the terminal may be used as a comparison object, for example, suppose the MCU finally determines the priority of each site as T11: 30; T12: 20; T13: 40; T14: 30; T21: 50 T22: 50; T23: 20. Among them, the venue T13 has applied for the chairman and has control over the meeting. At this time, the T11 application chairman, because the priority of the T11 is not T13, the application chairman fails. Unless the T13 releases the chairperson and the meeting does not have a higher priority than the T11, the T11 site will apply successfully. At this time, if T22 applies for the chairman, the chairman of T13 will be deprived because the priority of T22 is higher than the priority of T13.

It can be seen that the present invention implements conference control based on the priority of the conference control operation request sent by each terminal and/or terminal, so that conferences with different requirements can realize flexible scheduling and permission of the conference according to different conference policies configured. Control can meet the specific needs of users while reducing the cost of conference control R&D. Embodiment 2

Referring to FIG. 4, which is a schematic flowchart of a conference control method according to Embodiment 2 of the present invention, the method specifically includes the following steps:

Step 401: Receive a conference operation request of the conference terminal.

Step 402: Determine, according to the conference operable object list set by the conference management device for the conference terminal, whether the target conference terminal in the conference operation request is included in the conference operable list, and if yes, proceed to step 403, if no, Go to step 404;

When the conference operable object list is set in advance for the conference terminal, the method specifically includes: the conference management device divides the conference terminal into at least two groups; and sets different conference operable objects for the conference terminals in different groups. .

For example, there are four terminals participating in the conference, namely Tl, Τ2, Τ3, and Τ4, where Tl is a terminal that needs to be kept secret, and the conference television terminal is divided into two groups, that is, T1 is the first group, T2 , Τ3 and Τ4 are the second group. Set the operable objects for the terminal of the first group and the terminal of the second group respectively: T1, Τ2, Τ3, and Τ4, and 可2, Τ3, and Τ4 of the operable objects are Τ2, Τ3, and Τ4, Including Τ 1 , therefore, the terminal Τ 1 that is externally confidential cannot be used by terminals Τ 2, Τ 3, and Τ 4 Control. A preferred way is to place the externally secret terminal in a group with a higher MCU level and the other terminal at a lower level in the MCU level according to the MCU cascading hierarchy in the video conferencing system. At the same time, the terminal in the group with the highest level of the MCU is operated by all the terminals and the lower level of the own MCU1. Therefore, in the above scenario, the externally secreted T1 needs to be connected to the MCU1 with the highest level. The operable objects for setting T1 are Tl, Τ2, Τ3, and Τ4, and Τ2, Τ3, and Τ4 are connected to the lower-level MCU2, and the operable objects for setting Τ2, Τ3, and Τ4 are Τ2, Τ3, and Τ4, see Figure 5 Shown.

The embodiment further includes changing the pre-set conference operable object list according to the conference operable object list update information confirmed by the conference management device. In the example of FIG. 5, that is, the definition of the rights of the operable objects of the four conference terminals, such as T1, Τ2, Τ3, Τ4, etc., the original four terminals T1, Τ2, Τ3, Τ4 can be divided into four groups. Each group has a different level, and the level becomes smaller in turn. 譬^口: T1 can only operate Tl, Τ2, Τ2 can operate Τ2, Τ3, Τ4, Τ3 can only operate Τ3, Τ4; Τ4 can only operate Τ4.

It can be understood that the above example uses the method of grouping and defining the operable rights of each group of conference terminals to control the rights, and there is also a way to control the rights by using the hierarchical method, because the conference system The networking structure in the network is generally fixed. After the networking structure is determined, we define different conference control devices (for example: MCU and/or gateway and other devices that can handle audio and video) with different levels, as shown in Figure 5. In the above, we can define MCU1 as a high-level MCU and MCU2 as a low-level MCU, so that the conference terminal T1 connected to the high-level MCU (ie: MCU1) has a higher operable object level and is connected to the lower-level MCU (ie, : MCU2) The conference terminal has a lower operational object level. Beam process; beam process.

As can be seen from the above embodiments of the present invention, in the conference system, terminals are grouped in advance, and a list of conference operable objects of each terminal in different groups is specified, only when the operable object in the operation request proposed by the terminal is in the When the range of the object list is operable, the terminal is allowed to perform the specified operation, otherwise, the operation request of the terminal is rejected. Therefore, the information security of each terminal in the conference system is guaranteed. And confidentiality requirements. In addition, the existing conference system can be smoothly upgraded and modified without changing the hardware equipment.

The embodiment of the present invention not only ensures the information security and confidentiality requirements of each terminal in the conference system, but also changes the conference operable object list update information confirmed by the conference management device, and changes the conference set in advance for the conference terminal to be operable. A list of objects to more flexibly control each terminal in the TV system to better meet the needs of users. Please refer to FIG. 6, which is a schematic flowchart of a conference control method according to Embodiment 2 of the present invention. This embodiment is a specific implementation manner of the method for controlling the conference terminal. In this implementation, there are four terminals participating in the conference, namely T1, Τ2, Τ3, and Τ4, where Tl is a terminal that needs to be kept secret, and is not allowed. Other terminals perform any operations on it. The method specifically includes the following steps:

Step 601: When the conference is held, the terminals participating in the conference are grouped by the conference management device. According to the MCU cascade hierarchy in the video conference system, the externally secret terminal is placed in a group with a high MCU level, and other terminals are Placed in a group with a low MCU level. In this embodiment, the terminal T1 is connected to the port of the MCU1, and the terminals T2, Τ3, and Τ4 are connected to the port of the MCU2, wherein the MCU1 is the master MCU and the MCU2 is the slave MCU.

Step 602: Set a conference operation object to the terminal in each group by using the conference management device. In this embodiment, the conference operation authority of the terminal is set by setting an operation object of the terminal as an example. The setting of the conference operation permission is not limited to this method. When setting the operation object of the terminal, the conference management device sets the control list of T1 in MCU1 to T1, Τ2, Τ3, and Τ4, and sets the control lists of Τ2, Τ3, and Τ4 in MCU2 to Τ2, Τ3, and Τ4. Therefore, the operation object of the terminal T1 is all terminals, and the operation objects of the terminals Τ2, Τ3, and Τ4 are Τ2, Τ3, and Τ4. Here, the operation type of each terminal is set to be the same, that is, in this embodiment, the security and confidentiality of a certain terminal (T1) are ensured only by setting the operation object of each terminal.

Step 603: MCU1 and MCU2 respectively forward the control list to the terminal T1 and Τ2, Τ3,

Τ4;

Among them, MCU1 forwards the control list containing Tl, T2, Τ3, and Τ4 to Tl, and MCU2 searches for control containing Τ2, Τ3, and Τ4, and the J table is further forwarded to Τ2, Τ3, Τ4. Terminal T1 can control Tl, Τ2, Τ3, and Τ4, and terminals Τ2, Τ3, and Τ4 can control Τ2, Τ3, Τ4, because J3⁄4, 对卜 The secret terminal T1 cannot be controlled by the terminals T2, Τ3 and Τ4.

Step 604: After the terminal respectively submits an operation request to the MCU1 and the MCU2, the MCU1 and the MCU2 query the control list to determine whether there is an operated terminal in the control list, and if yes, go to step 605, if no, go to step 606;

After the terminal Τ2, Τ3, or Τ4 requests the MCU2 to control T1, the MCU2 first queries the control list of the terminal Τ2, Τ3, or Τ4, and when it is determined that the control list of the terminal Τ2, Τ3, or Τ4 has T1, the process proceeds to step 605. When it is determined that there is no T1 in the control list of the terminal Τ2, Τ3 or Τ4, the flow proceeds to step 606.

Step 605: Allow the terminal to perform the conference operation, and proceed to step 607;

Step 606: Reject the terminal to perform the conference operation, and proceed to step 607;

Step 607: Update the conference operable type list according to the user's needs, and send the conference operable type list update information to the MCU1 and the MCU2.

When the conference operation object set in advance for the conference terminal is dynamically adjusted by the conference management device, the conference management device delivers the new control list to the MCU1 and the MCU2, and the MCU1 and the MCU2 update the control list according to the new control. The list is forwarded to the terminals T1 and T2, Τ3, Τ4, respectively. When the terminal performs the conference control request, MCU1 and MCU2 determine whether the terminal's conference control request is legal according to the new control list. In addition, during the meeting, it is also possible to create new groups, merge or split existing ones. Then, the conference operation object is set to the terminal in each new group by the conference management device.

In the above steps 602, 603 and 607, the grouping, the designation of the conference operation object, and the dynamic adjustment may be performed not only by the conference management device, but also by the conference convener, for example, a terminal that initiates the conference, and the like. Similarly, the grouping settings can also be set by the chairman terminal.

After the conference management device groups the terminals, the packet result is transmitted to each conference control device through a standard protocol. The transmission method of the standard protocol specifically includes: The Η323 protocol can be transmitted through the NonStandardMessage in the ITU Η245 recommendation; Transmission through the INFO field [RFC2976]; H320 protocol can be transmitted through LSD (low rate data) channel, HSD (high rate data) channel, MLP (multilayer protocol) channel, H-MLP (high bandwidth multi-layer protocol) channel. The conference control device may specifically be an MCU and/or a gateway and other devices that can process audio and video.

The embodiments of the present invention are not limited to the second-level cascade networking structure, and can also be used for the N-level MCU cascade. Network structure. In the networking structure of the N-level MCU cascade, all the terminals in the conference are divided into N groups, the packet 1 can control all terminals in the conference, the packet 2 can control all terminals except the packet 1, and so on. The packet N cannot control the terminal in its upper-level cascading direction, and can only control the terminal in the packet. In the cascading MCU networking, the cascading level of the MCU is predefined in scheduling the conference. For an N-level MCU cascaded network, each MCU can only have one superior MCU (except the top-level MCU) and one direct lower-level MCU (except the lowest-level MCU). The cascading hierarchy is independent of the physical spatial location in which it is located. Embodiment 3

Referring to FIG. 7, FIG. 7 is a schematic flowchart of a conference control method according to Embodiment 3 of the present invention, where the method specifically includes the following steps:

Step 701: Receive a conference operation request of the conference terminal.

Step 702: Determine, according to the conference operation type list set by the conference management device in advance for the conference terminal, whether the operation type of the conference operation request in the conference operation request is included in the conference operation type list, and if yes, go to step 703. If no, proceed to step 704;

Optionally, when the conference operation type list is set in advance for the conference terminal, the method includes: grouping the conference terminal into at least two groups according to group information of the conference management device; and setting different conference operations for conference terminals in different groups. Types of.

Similarly, taking the scenario in FIG. 5 as an example, in this case, when the operation objects of the terminals T1, Τ2, Τ3, and Τ4 are not set, it is considered that the control objects of the four terminals are the same, and all are T1, Τ2, Τ3 And Τ 4. Wherein, T1 is a terminal that needs to be kept secret, and the TV terminal is divided into two groups, that is, T1 is the first group, and T2, Τ3, and Τ4 are the second group. Set the operation type for the terminal of the first group and the terminal of the second group respectively: The operation type of T1 is broadcast terminal, select watch, apply for speaking, name speech, set voice control switch, free discussion, send auxiliary stream, set multi-picture and broadcast For all operation types such as multi-picture, the operation type of Τ2, Τ3, and Τ4 is broadcast. Therefore, the externally secret terminal T1 cannot be controlled by Τ2, Τ3, and Τ4 to perform any operation other than broadcasting. One of the preferred ways is: According to the MCU cascading hierarchy in the video conferencing system, the externally secret terminal is placed in a group with a high MCU level, and the other terminals are placed in a group with a low MCU level. At the same time, each terminal in the two groups has the same operation object and different operation types. Therefore, taking the above scenario as an example, Tl is connected to the highest-level MCU1, and sets the operation type of T1 to broadcast terminal, select watch, apply for speech, name speech, set voice control switch, free discussion, send auxiliary stream, set multi-picture and broadcast multi-picture, etc. T2, Τ3, and Τ4 are connected to the lower-level MCU2, and the operation types of Τ2, Τ3, and Τ4 are broadcast.

Step 703: Accept the conference operation of the operation type by the conference terminal to the target conference terminal;

In addition, it is also possible to pre-set the conference operation object list and the conference operation type list for the conference terminal by grouping. Similarly, taking the above scenario as an example, T1 is a terminal that needs to be kept secret, and T1 and Τ2 are divided into the first group, and Τ3 and Τ4 are divided into the second group. The operation object and the conference operation type are respectively set for the terminal of the first group and the terminal of the second group: the operation objects of the terminals T1 and Τ2 of the first group are T1, Τ2, Τ3, and Τ4, and the terminals Τ3 and Τ4 of the second group The operation objects are Τ3 and Τ4, and the operation types of T1 in the first group are all types of operations such as broadcast terminal, selective viewing, application for speaking, naming speech, setting voice switching, free discussion, sending auxiliary stream, setting multi-picture and broadcasting multi-picture. The operation type of the first group is 广播2, and the operation type of Τ3 and Τ4 is the same for the broadcast, terminal selection All operation types such as picture and broadcast multi-picture. Therefore, the externally secret terminal T1 cannot be controlled by Τ3 and Τ4, and at the same time, it cannot be controlled by Τ2 to perform any operation other than broadcasting.

Correspondingly, determining whether the operation object and the operation type in the conference operation request are the conference operation object and the conference operation type, and if yes, determining that the terminal has the permission to perform the conference operation, and if not, It is determined that the terminal does not have the authority to perform the conference operation. The present invention does not limit the judgment order of the conference operation object and the conference operation type, and may first determine whether the operation object in the conference operation request is the conference operation object and then determine the operation type in the conference operation request. Whether the operation type in the conference operation request is the conference operation type, and whether the operation object in the conference operation request is the conference operation object is determined.

As can be seen from the above embodiments of the present invention, in the conference system, the terminals are grouped in advance, and a list of conference operable types of each terminal in different groups is specified, and only when the terminal proposes an operation, When the operation type in the operation is in the range of the operation type list, the terminal is allowed to perform the specified operation; otherwise, the operation request of the terminal is rejected. Therefore, the information security and confidentiality requirements of each terminal in the conference system are guaranteed. In addition, the existing conference system can be smoothly upgraded and modified without changing the hardware equipment.

In addition to ensuring the information security and confidentiality requirements of each terminal in the conference system, the embodiment of the present invention also changes the conference operable object list set in advance for the conference terminal according to the user's needs, so as to more flexibly control the television system. Each terminal is more suitable for the needs of users. Embodiment 4
