Description

Method, device and system for conference control

This application claims priority to Chinese Patent Application No. 200910109561.4, entitled "Method, Apparatus and System for Conference Control", filed on August 7, 2009, the entire contents of which are incorporated by reference. In this application.

Technical field

The present invention relates to multimedia communication technologies, and in particular, to a method, apparatus and system for conference control. Background technique

A video conferencing system is a system that enables remote audio and video communication between two or more parties. The entity includes: a conference terminal (terminal) and an MCU (Multipoint Control Unit), wherein the conference terminals are distributed in different conference sites, and the MCU is distributed in the network side, which generally includes a multipoint controller MC (Multipoint). Controller) and Multipoint Processor (MP) are used to complete conference control. In conference control, the most important thing is to involve sound and image processing and control in conference control. Figure 1 shows a scenario in which the MCU mixes and controls the conference terminals in the conference. The three conference sites (site A, site B, and site C) transmit their own audio signals to the MCU through the MCU. The audio signals of the venues are mixed, and the final mixing signal is transmitted to each venue according to the mixing principle of "this site does not receive the data of the venue's mixing".

Among them, the existing conference television system generally only mutes and silences the operation of the venue audio: after the venue is muted, the sound of the venue cannot be heard by all the venues; after the venue is closed, the venue cannot hear the conference. All mute and closed operations are based on the entire conference level. The audio processing is very inflexible and cannot meet various personalized requirements. For example: Private chat between conferences during the conference without affecting the normal conference. Group discussions, etc.

The types of operations for video are: point name, broadcast, watch, and join multi-screen. The site will be named, broadcasted, and added to the multi-screen operation. The screen of the destination site will be seen by all participating venues; The viewing of the destination site, the destination site screen must be seen by another site; the only operations that result in a lack of application flexibility, can not meet the user's individual needs, such as: Without affecting the normal meeting of the meeting The conference site can customize its own video display content, for example: not displaying the video image of a certain venue, and not displaying its own video image to a certain venue.

Similarly, similar problems exist in the transmission of data during the conference. The film shared in the conference can only be controlled as a whole, sharing the film to all the conference venues, and not being able to personalize the settings according to the request of the data sharer. .

Based on the above problems in the prior art, the inventors conducted extensive analysis of the prior art in the process of completing the present invention, and found that the prior art has at least the following problems:

In the existing video conferencing, single-user, flexible audio and video and data control cannot be realized, which cannot meet the user's personalized audio and video and data operation requirements. Summary of the invention

In order to introduce the implementation process of the present invention in more detail, the implementation of the present invention will be described in detail below by way of specific embodiments.

Embodiment 1

Refer to Figure 3-6. The site A is used to mute the site B as an example.

In Figure 3, there are four conference sites (one conference terminal for each conference site) and one MCU, namely: conference site A, site B, site C, and site D. Four conference sites have four conference terminals. The solid line in Figure 3 indicates that each site transmits the code stream of the site to the MCU, and the dotted line indicates that the MCU transmits the audio after the mixing to each site.

For the sake of simplicity, the conference terminal corresponding to a certain conference site is represented by the corresponding serial number of the conference site.

The flowchart of Figure 4 is used to introduce the site A to the field B to be added to the mute list. In this way, the site A does not have the audio signal of the site B in the mixing result received by the MCU.

301. The MCU holds a multi-point video conference to create a conference mixer.

In the implementation of 301, in general, the MCU holds a multi-point conference to create a conference mixer, the mixer corresponds to a mixing list, and all the venues are included in the mixing list, and all the venues will be in the conference venue. The audio stream is sent to the audio decoder corresponding to the venue for decoding, and the decoded stream is sent to the mixer for mixing, and the conference mixer sends the mixed stream to the mixed stream. The audio encoder of each site is encoded by the audio encoder and transmitted to each venue;

302. Venue A proposes a request to add Field B to the silent list;

When implementing 302, there are three ways to achieve this:

(1) The site A can submit a request to the chair site (the venue hosting the meeting) to join the silent list corresponding to the site A. After the chairman's site agrees, execute 303;

(2) When there is no chair site, if the MCU pre-defined the corresponding rules, for example: If the corresponding site creates a silent list for a single site, directly perform the corresponding operation, and then execute 303;

(3) When there is no chair site, and there is no corresponding predefined rule in the MCU, execute 303 directly.

303. The MCU creates an independent mixer for the conference site Α';

In the implementation 303, the MCU creates an independent mixer Α' for the venue, and creates an independent mixing list for the independent mixer A', and identifies the mute list of the venue Β in the conference list in the mixing list. In the following conference mix list, that is, the audio of the site B does not appear in the mix table of the site A;

The following table shows the conference mix table:

304, independent mixer A' separately mixes the audio sent to the venue A, and the conference mixer mixes the audio sent to the other venues;

At the time of implementation 304, the conference mixer can process the mixed code stream sent to the conference site C and the conference site D according to the existing mixing principle. Since the processing process is prior art, no further description is provided herein. . The independent mixer A' mixes the audio sent to the venue A. There are two ways to implement it. See Figure 5 and Figure 6:

Method 1: Referring to FIG. 5, for the independent mixer Α' corresponding to the site A, the code stream of all the sites is directly sent to the independent mixer Α', and the identifiers of the transmission streams of each site are read to identify each The code stream, from which the code stream corresponding to the site 找到 is found, in the independent mixer A', the code stream identified as the site Β is removed from the mixed code stream, and according to the mixing principle, the venue does not accept its own audio. Code stream, In this way, the audio code stream transmitted to the site A is the code stream of the site C and the site D;

In a specific implementation process, the identifier of the corresponding site transport stream may be determined by using the corresponding port number;

Method 2: Referring to Figure 6, for the independent mixer Α' corresponding to the site A, the code stream obtained by mixing the conference mixer with the conference Α (that is, the mix of the site B, the site C, and the site D) The code stream is sent to the independent mixer Α', and the code stream of the field is sent to the independent mixer Α', and the conference stream is mixed by the independent mixer A' to subtract the conference stream from the conference stream. The code stream of the Β, the obtained mixed code stream is the mixed code stream sent to the conference site (that is, the code stream of the site C and the site D);

In the specific implementation process, the subtraction method in the time domain can be implemented, wherein the delay of the code stream that needs to be subtracted is consistent; of course, the subtraction of the code stream can also be implemented by means of spectrum subtraction, in specific See the process, you need to ensure the consistency of the phase;

305. The independent mixer A' sends the mixing signal for the site A to the A, and the conference mixer sends the mixed signal to the other site.

When the 305 is implemented, the mixed code stream sent to the site A is transmitted to the site A according to 304, and the mixed code streams obtained by the conference mixer are transmitted to the corresponding sites (site B, site C, and site D). Meeting place.

The above embodiment mainly uses the venue A to set the field B as its mute site, and the MCU establishes an independent mixer A for the site A to achieve independent mixing for the site A, to meet the individual mixing requirements of the site A. , Realize Site B to mute Site A. Those skilled in the art can understand that if there are multiple conference sites in the conference, a separate conference mute request is proposed, so that the MCU establishes an independent mixer for each venue that proposes the requirement, thereby completing personalizedization for the conference site. The mute requirement is limited by the length of the space. The applicability of the solution is illustrated by enumerating two conference terminals to propose the mute requirement.

For example, for the above example, assume that both the venue and the conference site B have a mute requirement, that is, the site A will be included in the mute list, and the site B will be included in the mute list, according to the steps described above. The MCU establishes separate mixers Α', Β' for site A and site B, respectively. And the corresponding mixing table is established for the venue A and the conference site B, wherein the independent mixer A' completes the separate mixing processing for the venue A, and the independent mixer B' completes the separate mixing processing for the venue B, the conference mix The sounder performs the normal site mixing process. Similar to the process of step 304 in the above embodiment, the mixing process of the site A and the site B can be completed by using the mode one or the second mode in the step 304, because other processes are similar to the above. The embodiment is not described here.

It can be understood that the above is for a site to use another site as a mute site. In a specific process, multiple sites will be used as a mute site. In the process of mixing, you need to Multiple sites are removed from the mixed audio stream, and are not described here.

Embodiment 2

In the following, the control of the audio stream of the site is described in the closed tone list. When the site C is placed in the closed tone list, the code stream sent to the site D does not include the code stream of the site C.

You can refer to the networking diagram of Figure 3, which includes four conference terminals and one MCU, that is, the conference terminals corresponding to each of the four conference sites: Site A, Site B, Site C, and Site D. The MCU completes the four conference venues. Tone processing, the solid line in Figure 3 indicates that each site transmits the code stream of the site to the MCU, and the dotted line indicates that the MCU transmits the audio after the mixing to each site.

In the following, the flow field C of the site C is added to the closed list through the flowchart of FIG. 7, so that the site D does not have the audio signal of the site C in the mixing result received by the MCU.

601. The MCU holds a multi-point video conference to create a conference mixer.

In the implementation of 601, in general, the MCU holds a multipoint conference to create a conference mixer. The mixer corresponds to a mixing list, and all the venues are included in the mixing list. All the venues will be in the conference venue. The audio stream is sent to the audio decoder corresponding to the venue for decoding, and the decoded stream is sent to the mixer for mixing, and the conference mixer sends the mixed stream to the mixed stream. The audio encoder of each site is encoded by the audio encoder and transmitted to each venue;

602. Venue C proposes a request to add Field D to the closed list;

When implementing 602, there are three ways to achieve this: (1) Site C may submit a request to the chairman's venue (the venue where the conference is presiding) to join the closed list corresponding to the venue C. After the chairman's site agrees, execute 603;

(2) When there is no chair site, if the MCU pre-defined the corresponding rules, for example: Allow the corresponding site to create a closed list for a single site, then directly perform the corresponding operation, and then execute 603;

(3) When there is no chair site, and there is no corresponding predefined rule in the MCU, execute 603 directly.

603. The MCU creates an independent mixer D for the venue D.

When the 603 is implemented, the MCU creates an independent mixer D' for the site D, and establishes an independent mixing list for the independent mixer D', and identifies the closed sound of the site D in the site C in the mixing list. In the list, it is reflected in the conference mix list below, that is, the audio of the site C does not appear in the mix table of the site D;

The following table shows the conference mix table:

604, the independent mixer D' separately mixes the audio sent to the venue D, and the conference mixer mixes the audio sent to the other venues;

At 604, the conference mixer can process the mixed code stream sent to the conference hall 8, the conference site B, and the conference site C according to the existing mixing principle. Since the processing process is prior art, it is no longer Narration. The independent mixer D' mixes the audio sent to the venue D. There are two ways to achieve this. See Figure 8 and Figure 9:

Method 1: Referring to Figure 8, for the independent mixer D' corresponding to the site D, all the meetings will be directly The code stream of the field is sent to the independent mixer D', and each code stream is identified by reading the identification of the code stream of each site, and the code stream corresponding to the site D is found therein. In the independent mixer D', the identifier is identified. The code stream of the site C is removed from the mixed code stream, and according to the mixing principle, the site D does not accept its own audio stream. Thus, the audio stream transmitted to the site D is the audio stream of the site A and the site B. ;

Method 2: Referring to FIG. 9, for the independent mixer D' corresponding to the site D, the code stream obtained by mixing the conference mixer for the site D (that is, the mix of the site A, the site B, and the site C) The code stream is sent to the independent mixer D', and the code stream of the field C is sent to the independent mixer D', and the venue is subtracted from the code stream obtained by mixing the conference mixer by the independent mixer D'. The code stream of C is the mixed code stream that is sent to the site D (that is, the code stream of the site A and the site B).

605. The independent mixer D' sends the mixing signal for the site D to the site D, and the conference mixer sends the mixed signal to the other site.

When the 605 is implemented, the mixed code stream sent to the site D is transmitted to the site D according to 604, and the mixed code streams obtained by the conference mixer are transmitted to the corresponding sites (site A, site B, and site C) respectively. Meeting place.

The above embodiment mainly uses the venue C to set the field D as its closed sound site, and the MCU establishes an independent mixer D' for the venue D to achieve an independent mixing for the venue D, to achieve a separate mix for the venue D. Requirement, the venue C is closed to the venue D. Those skilled in the art can understand that if there are multiple venues presenting separate conference silence requests during the conference, the MCU will establish an independent mixer for each venue that proposes the requirement, thereby completing the venue personality. The closed-loop demand is limited by the length of the space. The applicability of the scheme is illustrated by enumerating the two closed-end requirements of the conference terminal.

For example, for the above example, assume that both venue B and venue C have a closed-tone requirement, that is, venue B will be included in its closed list, and venue C will be included in its closed list, according to the foregoing. In the step, the MCU establishes separate mixers C' and D' for the site C and the site D, and establishes a corresponding mixing table for the site C and the site D, wherein the independent mixer C' completes the site C. Separate mixing process, independent mixer D' completes separate mixing of site D, conference mixer The conventional site mixing process is completed. Similar to the process of step 604 in the above embodiment, the mixing process of the site C and the site D can be completed by using the mode one or the second mode in step 604, because other processes are similar to the above implementation. For example, it will not be described here.

It can be understood that the above is for a site to use another site as a closed site. In a specific process, a site will also use multiple sites as a closed site, so that the MCU will be listed as A separate mixer is built in the venue of the closed list. In the process of mixing, multiple sites need to be removed from the mixed audio stream, and will not be described here.

The embodiments of the present invention can effectively meet the personalized service requirements of the conference terminals of the participating conferences by configuring corresponding resources for the corresponding requirements and completing corresponding operations for the personalized service requirements of the conference terminals.

Embodiment 3

The following describes the control of the video stream of the site through the blacklist of images.

Referring to Figure 3, there are four conference sites (site A, site B, site C, and site D) and an MCU, where each of the four sites corresponds to a conference terminal.

The conference terminal of the conference site A will be listed as the blacklist of the image in the field B. The MCU will broadcast the video image of the field A as an example to introduce the processing process. See Figure 10:

901. The MCU holds a multi-point video conference to create a video encoder and/or a video decoder. When the step 901 is implemented, when the supported video coding and decoding protocols of different conference terminals are different, the corresponding conference terminals need to be configured. Video encoder and video decoder. When the video codec protocols supported by multiple conference terminals are the same, a video encoder can be created for the site that supports the same protocol. The video protocol supported by each site is different as an example.

Referring to Figure 11, the MCU establishes a corresponding video decoder and video encoder for each conference terminal.

902. Venue A proposes a request to add Field B to the image blacklist;

When implementing 902, there are three ways to achieve this:

(1) Venue A can propose to the venue (the venue where the conference is presiding) to join venue B. A corresponding blacklist request for the image, after the chairman's site agrees, execute 903;

(2) When there is no chair site, if the MCU pre-defined the corresponding rules, for example: Allow the corresponding site to create an image blacklist for a single site, directly perform the corresponding operation, and then execute 903;

(3) When there is no chair site, and there is no corresponding predefined rule in the MCU, execute 903 directly.

903. Broadcast an image of the current site A;

When the 903 is implemented, the conference terminal corresponding to the chair site can be used to determine the image of the conference site A. The conference terminal corresponding to the conference site (different from the chair site) can be used to make a request to the chair site. After the chair site determines the video image of the broadcast site A, it is executed by the MCU.

904. The MCU sends the decoded code stream of the field A to the other site. After the MCU confirms that the site B adds the image blacklist to the site blacklist, the MCU does not send the decoded code stream of the field A video image to the site B.

When the implementation of the 904, the MCU needs to determine the blacklist of the image of the site to be broadcasted (in this example, corresponding to the site A), and when it is determined that the corresponding site identifier exists (in this example, corresponding to the site B), The video decoding code stream of the field A is no longer broadcast to the corresponding site. In this example, the above embodiment describes the implementation process of the image blacklist by broadcasting the video stream of a single site. The business introduces the implementation process of the corresponding image blacklist.

If the current multi-screen is broadcasted, the images of the sites A, B, and C are added to the multi-screen, as shown in Figure 12, where the conference terminal corresponding to the site A puts the field B into its image blacklist, so that more In the case of the picture broadcast service, the multi-picture sent to the site B does not include the picture of the site A. In FIG. 12, the video codec protocols supported by the conference terminals of the various sites are different, so that the MCUs are different. The conference terminal establishes a corresponding video encoder and video decoder.

The specific processing procedure is as shown in the flowchart shown in FIG. 13: 1101. The MCU holds a multi-point video conference to create a video encoder and/or a video decoder. In the process of implementing 1101, it is mainly considered whether the corresponding conference terminal of each site supports the same video codec protocol, when different conference terminals are used. When the supported video codec protocols are different, it is necessary to establish corresponding video encoders and video decoders for different conference terminals. When the video codec protocols supported by multiple conference terminals are the same, a video encoder can be created for the site that supports the same protocol.

1102. Site A proposes a request to add Field B to the image blacklist;

When implementing 1102, there are three ways to achieve this:

(1) The site A can submit a request for the blacklist of the image corresponding to the site A to the chairman terminal (the conference terminal corresponding to the chair site). After the chairman terminal agrees, execute 1103;

(2) When there is no chair terminal (that is, there is no chair site), if the MCU pre-defined the corresponding rules, for example: Allow the corresponding site to create an image blacklist for a single site, directly perform the corresponding operation, and then execute 1103. ;

(3) When there is no chair terminal (that is, there is no chair site), and there is no corresponding predefined rule in the MCU, execute 1103 directly.

1103, start the venue eight, B, C multi-picture broadcast;

When implementing 1103, there are three implementations:

(1) The multi-picture broadcast service can be initiated by the chairman terminal or the service platform (for example, RM (Resource Manager)) to the MCU, that is, when the chair site confirms that the video images of some sites need to be broadcast, To issue a multi-picture broadcast instruction to the MCU, execute 1104;

(2) The multi-picture broadcast service can be initiated by the general conference terminal to the MCU. When the MCU receives the multi-screen broadcast request from the general conference site, the MCU forwards the request to the chairman terminal for confirmation. , execute 1104; if the chairman terminal does not confirm the request, the process ends.

(3) Multi-picture broadcast service can be initiated by the general conference terminal to the MCU, when not When there is a chair terminal, according to the rules customized by the MCU (such as: allowing the participant terminal to make a multi-picture broadcast service request, or not allowing the multi-picture broadcast service request, or only opening the multi-picture broadcast service request for some terminals, etc.) If it is confirmed that the multi-picture broadcast service is allowed, the process 1104 is performed. If the request is not allowed, the process ends.

1104. The MCU confirms that the site B is added to the blacklist of the image corresponding to the site A, and the decoded code stream of the field A is not sent to the video encoder corresponding to the site B. The MCU sends the decoded code stream of the field B and the site C. All the venues for the conference;

In the process of the implementation of the method 1104, the MCU queries the blacklist of each conference terminal before performing the multi-picture broadcast service. In this embodiment, the MCU finds that the conference terminal of the conference site A lists the field B as its image blacklist. The decoded code stream of the field A is not sent to the video encoder corresponding to the site B. In this embodiment, the MCU sends the decoded code stream of the field B and the site C to all the conference sites;

1105. The video encoders corresponding to the conferences A, C, and D combine and encode the pictures of the fields A, B, and C. The video encoder corresponding to the site B combines the pictures of the fields B and C and performs video coding. The video encoder corresponding to the site sends the encoded video stream to the corresponding site.

In the implementation of 1105, the multi-picture combination technology, and the combined coding technology are existing mature technologies, and will not be described herein. The MCU sends the multi-screen combination of each site and the result after the encoding to the corresponding conference terminal.

It can be seen from the embodiment that the conference system can provide personalized audio and video operation services according to the requirements of each conference terminal, and brings a better experience to the user.

Similarly, there is another implementation manner for the conference terminal A to list the conference terminal B as its image blacklist, that is, the MCU does not send the code stream after the picture of the conference terminal B is decoded to the encoder corresponding to the conference terminal A, so that The conference terminal A does not encode the picture of the conference site B corresponding to the conference site. Thus, the conference terminal A (corresponding to the conference site A) does not see the conference site B (corresponding to the conference terminal B), and the implementation process is similar. The mute control in the audio is limited to the length and will not be described here. It can be understood that, for the sharing of data in the conference, a method similar to audio and video control can also be adopted, for example, the conference terminal of the conference site A shares the film (such as PPT) to other conference terminals in the conference, which can be similar to The way the image is blacklisted, the film is only shared to some venues. Since the implementation is similar to the image blacklist, it is limited to the length, and no further description is made here, but the corresponding embodiments that can be obtained by those skilled in the art according to the embodiments of the present invention are also included in the scope of the present invention.

The present invention further provides an embodiment of a conference control device. Referring to FIG. 14, the conference control device includes: a receiving unit 1201, configured to receive a personalized operation request for a service of a conference terminal; and a configuration unit 1202, configured to The personalized operation request implements the personalized setting corresponding thereto, and configures the corresponding conference resource according to the personalized setting.
