Description

Method for obtaining the current event spokesperson in the conference, media server

This application claims the priority of the Chinese Patent Application filed on September 7, 2007, the Chinese Patent Office, Application No. 200710146076.5, entitled "Method for obtaining the current event spokesperson, media server" in the conference, the entire contents of which are incorporated by reference. Combined in this application.

Technical field

The present invention relates to the field of multimedia communication technologies, and in particular, to a method for obtaining an event speaker in a conference, a media server, a media controller, and a media processor.

Background technique

The media server device can be functionally divided into two functional entities: a media controller (MC) and a media processor (MP). The physical device corresponding to the MC is the Media Gateway Controller (MGC), which is mainly used to complete the management of the conference control, and implement the functions of resource management and access control for the MP device. The physical device corresponding to the MP is a media gateway (MG, Media Gateway), which is mainly used to complete the collection and distribution of conference audio, video and data media, and to implement audio mixing, video picture switching, codec and rate adaptation, and the like. Handle related functions.

The interface protocol between MC and MP is the H.248 protocol. The H.248 protocol is the Media Gateway Control Protocol H, which is used to separate call control from media conversion. The H.248 protocol describes the link between media control and the media processor. The media gateway controller controls and manages the media gateway and the H.248 endpoint through the protocol, and the media gateway also converts different types of access modes into RTP/RTCP streams suitable for transmission over the IP network, thereby implementing a packet network. Interoperate with the PSTN network. There are two basic components in the H.248 protocol: Termination and Context. The various resources on the media processor are abstractly represented as endpoints. The combination between endpoints is abstracted as a context. The context can contain multiple endpoints, and thus the topology is used to describe the interrelationship between the endpoints. Based on this abstract model of the protocol, the connection of the call is actually the operation of the endpoint and context. This operation is done by commands (Request) and Request (Reply) between the MC and the MP. The parameters carried by the command, also called descriptors, are classified into categories: Property, Signal, Event, and Statistic. The parameters with business relevance are logically aggregated into a package.

Meetings can be divided into audio conferencing, video conferencing, and data conferencing, depending on the media used for the meeting. In the audio conference service, when the state of the endpoint representing the user is changed from no speaking to speaking and being mixed by the mixer, the endpoint state is referred to as an active speaking state, and the user is referred to as an active speaker. When the number of conference speakers is greater than 1, the participants should be able to hear the voices of several speakers at the same time. At this time, the MP will perform the corresponding mixing processing on the audio from multiple endpoints according to the mixing method specified by the MC, and then Outputs the mixed audio stream to the specified endpoint, and the specified endpoint hears the mix audio stream of the currently active speaker.

In a conference that includes audio media, it may be necessary to display at the user terminal whether the user is a current event speaker, so that the participant can know which users are currently the speaker. In the prior art, although the MP has the ability to detect the event spokesperson, the MC cannot obtain the information of the current event spokesperson from the MP, and therefore cannot display whether the user is the current active spokesperson in the user terminal.

Therefore, in carrying out the creation process of the present invention, the inventors found that at least the following problems exist in the prior art: The MC cannot obtain the current event speaker information from the MP.

detailed description

Embodiments of the present invention provide a method for obtaining a current active speaker in a conference, a media server, a media controller, and a media processor. In order to make the technical solutions of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a flow chart of a signal of a first embodiment of a method for obtaining a current active speaker in a conference of the present invention. The conference in this embodiment is an audio conference, and the media processor reports the current active speaker list of each user endpoint in the conference.

The specific process includes: Step 101: The media controller instructs the media processor to detect and report information related to the current speaker.

The information related to the current speaker may be a list of currently active speakers for each user endpoint, including other user endpoint identities that are heard by the user endpoint in the current participating conference, or wildcards used to represent the user's punctuation;

The information related to the current speaker may also be a list of listeners of the current event speaker, including the user endpoint identifier of the current active speaker's audience or a wildcard used to indicate the client's punctuation;

The information related to the current speaker may also be user information in a speaking state, including a user endpoint identifier in an uttered state or a wildcard character used to represent the user's punctuation.

In this embodiment, the information related to the current speaker is a list of currently active speakers for each user endpoint.

The media controller can instruct the media processor to periodically report a list of currently active speakers for each user endpoint.

Since each user endpoint separately reports the list of active speakers that can be heard by the user, there is a large amount of report information. To reduce the amount of reported data, the media controller can also instruct the media processor to report the current activity of each user endpoint that has changed. List of speakers.

The media controller can also instruct the media processor to detect and periodically report the list of currently active speakers for each user endpoint that has changed. If the active speaker list of a user endpoint does not change, even if the reporting interval is reached, the media processor does not report the active speaker list of the user endpoint.

The essence of the change in the list of active speakers is that the content of the mix list changes, and the situation that causes the change is: the user changes from speaking to stopping, or the user changes from not speaking to starting to speak, or the volume of the user speaking is increased or decreased.

In this embodiment, the media controller instructs the media processor to add the specified user endpoints A, B, C, and D to the conference context by adding an ADD. Request command, and simultaneously instructs the media processor to detect the user endpoints A, B. , C, D, the list of active speakers and the time interval for periodic reporting.

Step 102: The media processor detects information related to the current speaker;

In this embodiment, the media processor detects a current active speaker list of each user endpoint. After receiving the ADD.Request command of the media controller, the media processor returns an ADD.Reply message to the media controller, and starts detecting the active speaker list of the user endpoints A, B, C, and D. Step 103: Report the information related to the current speaker to the media controller. In this embodiment, the media controller instructs the media processor to periodically report the current active speaker list of each user endpoint that has changed.

If the indication carries the reporting time interval information, the media processor reports the current active speaker list of the changed user endpoint according to the reporting time interval carried in the indication; if the indication does not carry the reporting time interval information The reporting time interval may be set in the media processor, and the media processor reports the current active speaker list of the changed user endpoint according to the reporting interval set by the media processor.

For example, the endpoints 8, B, C, and D representing the user participate in the conference, and the media controller sets the number of mixes n of endpoints A, B, C, and D to be 2, 3, 3, and 1, respectively. When the upper 4 艮 interval is reached and the user's active speaker list changes, the current speaker is endpoints A, B, D, and the volume is sorted as endpoints A, B, and D because the active speaking state endpoint itself does not participate in the mix. According to the number of mixes set by each endpoint, endpoint A hears the speech of endpoint B, and the list of reported active speakers includes endpoint B; endpoint B hears the endpoints A and D, and reports The event speaker list contains endpoints A and D; endpoint C hears the mix of endpoints A, B, and D. The reported event speaker list contains endpoints A, B, and D; endpoint D can only hear The speech of the endpoint A with the highest volume, the endpoint A of the reported event speaker list.

Step 104: The media controller acquires event speaker information in the current conference according to the information about the current speaker.

In this embodiment, after receiving the Notify.Request request reported by the media processor, the media controller returns a notification response (Notify.Reply) message to the media processor, and performs a speech according to the reported user endpoints eight, B, C, and D. For the list of people, get the spokesperson for the event in the current meeting as endpoints eight, B, and D.

After the event speaker in the current meeting is obtained, the event speaker in the current meeting can be displayed or processed in the user terminal.

For example, the media controller can notify the user server through the conference event defined in RFC4722

(AS, Application Server), the AS is responsible for controlling the user endpoints A, B, C, D to show which current active speakers are. At the same time, the event spokesperson itself can also be displayed. For example, the user terminal represented by endpoint A can display endpoints A and B as current active speakers in the conference.

The existing Multipoint Conference Control Protocol H.248 defines the following packages for audio conferencing: Volume Control Package): The volume control package is used to define a feature to set the volume of media received from the participant. The MC can instruct the MP to set the volume level of a certain participant by the volume level threshold. The MP can be mixed using the volume level.

Volume Detection Package: The volume detection package defines an event that indicates that the participant's volume exceeds the threshold. The MC can specify the volume level threshold through the volume detection packet. When the audio volume level exceeds the threshold, the MP should send a Notify message to the MC.

Volume Level Mixing Package: An algorithm that defines the endpoint for audio mixing. The parameters include the mix volume level and the maximum mix. The MC instructs the MP to set the mix volume level for a particular conference. When the volume of a participant exceeds or equals the volume level, the media stream sent by the participant will be used for the mix. When the volume of a participant is below the threshold, the media stream sent by the participant will not be used for the mix. The MC instructs the MP to set the maximum number of mixes n for a particular conference. This parameter is assigned to all participants who are willing to hear the first n loudest speakers. At this time, the MP will mix the voices of the speakers with the highest volume of the first n volumes whose volume is greater than or equal to the threshold, and output the mixed sounds to the respective relevant endpoints.

Each of the endpoints in the conference can set different mix volume level and mix value. When the mixing volume level of each endpoint is the same, and the number of mixing squares heard is the same, the mixing strategy is the same. When the mixing volume level of each endpoint is different, the number of mixing squares heard is not the same. At the same time, it is called a mix strategy.

Mixing Volume Level Control Package: The Mix Level Control Package defines a set of attributes that control the volume level of each participant to specify a participant output according to a certain mixing algorithm. Remix media.

In order to implement the media processor to report the current active speaker list of each user endpoint to the media controller, the event packet of the current active speaker list is reported in the H.248 protocol, and the event packet indicates that the MP reports the current user endpoints. List of event speakers.

In order to implement that the media controller instructs the media processor to periodically report the current active speaker list of each user endpoint, the event package may further include an optional reporting time interval. When the event packet has a reporting interval, the media processor reports the current active speaker list of each user endpoint according to the reporting interval in the event packet; when there is no reporting interval in the event packet, the media processor The current active speaker list of each user endpoint can be reported according to the reporting interval set in the media processor.

In order to implement the media controller to instruct the media processor to report the change of each user endpoint currently live The event spit list may further include an indication that the media processor is required to report the change of the current active speaker list of each user endpoint. The media processor may report the current active speaker list of each user endpoint that changes according to the indication information.

The list of active speakers is the list of users currently participating in the mix, and the list contents are the endpoint IDs indicating the currently active speakers.

Referring to FIG. 2, it is a flow chart of a signal of a second embodiment of a method for displaying a current active speaker in a conference of the present invention. The conference in this embodiment is an audio conference, and the media processor reports the audience list of the currently active speaker in the conference.

The specific process includes:

Step 201: The media controller instructs the media processor to detect and report information related to the current speaker.

In this embodiment, the information related to the current speaker is a listener list of the currently active speaker, and the listener list of the current active speaker includes other user endpoint identifiers that hear the user's voice or wildcards used to indicate the user's punctuation.

The media controller can instruct the media processor to periodically report the listener list of the currently active speaker. Since each user endpoint separately reports the audience list of the event speaker, there is a large amount of report information. To reduce the amount of reported data, the media controller can instruct the media processor to report the listener list of the current active speaker who has changed.

The media controller can also instruct the media processor to detect and periodically report a list of listeners of the currently active speaker who have changed. If the audience list of an event spokesperson has not changed, even if the escalation time is reached, the media processor does not report the audience list of the event spokesperson.

In this embodiment, the media controller instructs the media processor to add the specified user endpoints A, B, C, and D to the conference context by adding an ADD. Request command, and simultaneously instructs the media processor to detect the user endpoints A, B. , C, D event speaker list and periodic reporting interval.

Step 202: The media processor detects information related to the current speaker;

In this embodiment, the media controller indicates a list of listeners of the current active speaker whose media processor cycle has changed.

After receiving the ADD.Request command from the media controller, the media processor returns an ADD.Reply message to the media controller and begins to detect the listener list of the active speaker. Step 203: Report the information related to the current speaker to the media controller. In this embodiment, the media controller indicates the listener list of the current active speaker whose media processor cycle changes.

If the reporting time interval information is carried in the indication, the media processor reports the listener list of the currently active speaker that has changed according to the reporting time interval carried in the indication; if the reporting time interval information is not carried in the indication, The reporting time interval can be set in the media processor, and the media processor reports the current active speaker list of the changed user endpoint according to the reporting interval set by itself.

When the state of the user's endpoint changes, the content of the listener list changes. You can check the mixer to get the list of listeners of the current active speaker.

For example, on behalf of the user's endpoints eight, B, C, D participate in the conference, the media controller sets the endpoint A,

The number of mixes of B, C, and D are 2, 3, 3, and 1, respectively. When the upper time interval is reached and the user's active speaker list changes, the current speaker is the endpoints A, B, D, and the volume is sorted as the endpoint.

A, B, D, because the active speech state endpoint itself does not participate in the mix, so according to the number of mixes set by each endpoint, the speech of endpoint A is heard by endpoints B, C, D, and the listener of endpoint A is reported. The list contains endpoints B, C, D; the endpoint B's speech is heard by endpoints A, C, the reported endpoint B's listener list contains endpoints A, C; endpoint C does not speak, will not be heard, no listeners; endpoint D The speech is heard by endpoints B, C, and the listener list of endpoint D is reported to contain endpoints B and C.

Step 204: The media controller acquires event speaker information in the current conference according to the information about the current speaker.

After receiving the Notify.Request request reported by the media processor, the media controller returns a notification response (Notify.Reply) message to the media processor, and the media controller obtains the current active speaker endpoint VIII, B,

C, D listener list statistics, found that endpoint A appears in the endpoint B array, indicating that endpoint A is currently listening to endpoint B speaking; endpoint B appears in the array of endpoints A and D, indicating that endpoint B is currently hearing endpoint eight D speaks; endpoint C appears in all arrays, indicating that endpoint C is currently listening to endpoints A, B, and D; endpoint D appears in the endpoint A array, indicating that endpoint D is currently hearing endpoint A speaking, and the media controller gets current The user represented by endpoints A, B, and D is speaking, that is, the current active speaker is the endpoint,

B, D.

After getting the event spokesperson in the current meeting, you can put the event spokesperson in the current meeting in the user. The terminal performs display or performs other processing.

For example, the media controller can notify the AS through the conference event defined in RFC4722, and the AS is responsible for controlling the user endpoints eight, B, C, and D to show which current active speakers are. At the same time, the event spokesperson itself can also be displayed. For example, the user terminal represented by endpoint A can display endpoints A, B, and D as the current active speaker in the conference.

In order to implement the media processor to report the listener list of the current active speaker to the media controller, the listener list event package of the current active speaker is reported in the H.248 protocol, and the event packet indicates that the MP reports the current active speaker. Listener list.

In order to implement that the media controller instructs the media processor to periodically report the audience list of the currently active speaker, the event package may further include an optional reporting interval. When the event packet has a reporting interval, the media processor reports the listener list of the currently active speaker according to the reporting interval in the event packet; when there is no reporting interval in the event packet, the media processor may The listener list of the currently active speaker is reported according to the reporting interval set in the media processor.

In order to enable the media controller to instruct the media processor to report the listener list of the currently active speaker that has changed, the event package may also include indication information that requires the media processor to report a change in the list of pre-active speaker listeners. The media processor can report the listener list of the current active speaker that has changed according to the indication information.

Please refer to FIG. 3 , which is a signaling flow diagram of a third embodiment of a method for acquiring a current active speaker according to the present invention. The conference in this embodiment is an audio conference, and the media processor reports a single user information in a conference state in the conference.

The specific process includes:

Step 301: The media controller instructs the media processor to detect and report information related to the current speaker.

In this embodiment, the information related to the current speaker is the user information in the speaking state. The indication may also carry a volume level threshold. The media controller instructs the media processor to detect and report the user information in the speaking state. The specific manner is that the media controller instructs the media processor to report the volume is greater than or equal to the level. The value of the user's information.

The media controller may also instruct the media processor to periodically report information of the user who is in the active speaking state, that is, the volume is greater than or equal to the threshold. Since each user endpoint separately reports the audience list of the event speaker, there is a large amount of report information. To reduce the amount of reported data, the media controller can instruct the media processor to report the changed user information in the active speaking state.

The media controller can also instruct the media processor to detect and periodically report the changed user information in the active speaking state. If the user information in the active speaking state has not changed, the media processor does not report the user information even if the reporting time interval is reached.

The user information includes a user endpoint identifier in a speaking state or a wildcard character used to represent the client endpoint.

In this embodiment, the media controller instructs the media processor to report the current active speaker at a single location. In this embodiment, the media controller uses the ADD.Request command to instruct the media processor to add the endpoints A, B, C, and D to the conference context, and instruct the media processor to detect the user represented by the endpoints A, B, C, and D. The state changes and the volume level is wide.

Step 302: The media processor detects a current speaking state of the user.

In this embodiment, after receiving the ADD.Request command of the media controller, the media processor returns an ADD.Reply message to the media controller, and starts detecting the speaking states of the user endpoints A, B, C, and D, That is, the volume level value.

Step 303: Report the information related to the current speaker to the media controller.

In this embodiment, the media controller instructs the media processor to periodically report the user information in the speaking state.

If the reporting time interval information is carried in the indication, the media processor performs the user information in the speaking state according to the upper time interval carried in the indication; if the reporting time interval information is not carried in the indication, When the reporting time interval is set in the media processor, the media processor reports the user information in the speaking state according to the reporting interval set by the media processor.

For example, in the current conference, endpoint A speaks first, the volume exceeds the threshold, the media processor reports endpoint A to the media controller, endpoint D then speaks, and the volume exceeds the threshold, and the media processor reports endpoint D to the media controller. The media controller retains endpoint D.

If the user represented by multiple endpoints becomes the active speaker and the volume is greater than or equal to the volume level threshold, the user representing the endpoint with the highest volume is reported to the MC.

For example, in the current conference, endpoints A and D speak at the same time, the volume exceeds the threshold, and the endpoint D The volume is greater than the volume of endpoint A, and the media processor reports endpoint D to the media controller.

Step 304: The media controller acquires event speaker information in the current conference according to the user information in the speaking state.

For example, the media controller can also notify the AS through the conference event defined in RFC4722, and the AS is responsible for controlling the user endpoints A, B, C, and D to show which current active speakers are. For example, endpoint D can display endpoint D as the current active speaker in the conference.

In order to implement the media processor to report the user information in the speaking state to the media controller, the H.248 protocol adds a user information event packet that is reported in the speaking state, and the event packet indicates the user who is in the speaking state on the MP. information.

In order to implement the media controller to indicate that the media processor periodically reports the user information in the speaking state, the event packet may further include an optional reporting time interval. When the event packet has a reporting interval, the media processor reports the user information in the speaking state according to the reporting interval in the event packet; if there is no reporting interval in the event packet, if the media processor is in the media processor When the reporting interval is set, the user information in the speaking state is reported according to the reporting interval set in the media processor.

In order to implement the user information indicating that the media controller is in the speaking state on the media processor, the event package may further include user information in the speaking state that requires the media processor to change. The media processor may report the changed user information in the speaking state according to the indication information.

The user information in the speaking state is the endpoint identifier indicating the currently active speaker.

The method for displaying the current active speaker in the conference provided by the embodiment of the present invention can not only enable the media controller to obtain the current event speaker in the audio conference, but also can be applied to other types of multimedia conferences.

The method for obtaining the current active speaker in the conference provided by the foregoing embodiment of the present invention, the media controller can instruct the media processor to report the user information in the speaking state, and obtain the active speech in the current conference according to the user information in the speaking state. people.
