In recent years, video conferencing has become a tool that is often used in the busy business world. The use of video conferencing can not only avoid the situation that participants need to travel to and fro, but also make the meeting more real-time and more efficient.

Generally speaking, the mode of video conferencing is as follows: the initiator first initializes a conference connection, and then establishes a connection with participants from other places. When the conference is in progress, if the speaker has files to share with others, he will usually Use different data transmission mechanisms or standards to transmit the file content of the presentation and the interactive screen content of the on-site environment, for example, use ITU-T H.239 and H.264 to transmit the image screen of the presentation data and the audio-visual screen of the venue environment in various places .

Although the above-mentioned video conferencing method is quite common, the video conference carried out according to such a method has the following defects: First, since the data of the briefing is provided by the speaker in the process, other participants are not aware of the data on the briefing. When you have an opinion, you often need to guide the speaker/reporter where your doubts are by oral means, such as the broken line 1 in the fifth picture on the third page or the text description in the second line on the fifth page, etc., use The way this is directed is not intuitive.

In addition, the way this kind of meeting is carried out tends to be one-way rather than interactive, that is, participants from different places participate in the meeting centered on the meeting host/briefing speaker, but it is impossible for participants from different places to interact with each other. The connection of communication makes it possible for the marking and description of presentation data not to communicate with each other through a network connection during the meeting, but to allow most participants to participate in the meeting through passive reception in a way similar to broadcasting.

Most general video conferencing uses the H.323 protocol for real-time video and audio and related data transmission, and H.323 is actually composed of a series of sub-protocols, including H.264, H.245, H.239 and H.460 wait. Please refer to FIG. 1 , which is a schematic diagram of the composition of the packet content of a video conference generally conducted through the H.323 protocol. It can be seen from the figure that when the conference device is conducting a video conference, the transmitting end 101 will first encapsulate the data content in H.239, H.264, and H.245 formats into real-time video and data packets in H.323 format, and then The H.323 data packet sent by the transmitting end 101 is transmitted to the receiving end 105 through the network 103, and the receiving end 105 disassembles and restores the content of the H.323 data packet after receiving it.

Although there are quite a lot of sub-protocols of H.323, only a few types related to the present invention are marked in Fig. 1, including: H.239 as the content of the transmission briefing, H.264 for the transmission of the video screen of the conference site, and the control communication H.245 package, wherein H.245 provides a space for users to define themselves, so in the preferred embodiment of the present invention, the H.245 protocol is used as the channel for individual conference devices to communicate with each other in the preferred embodiment , to define the method of identification tags for marking the source of each conference device in the conference. For the detailed method, please refer to the following instructions.

Please refer to Fig. 2a and Fig. 2b, a preferred embodiment of the present invention proposes a method and system for identifying label presentation, which is applied to multiple conferencing devices connected through the network 203 for video conferencing, and according to user The operation type of the conference device is divided into a video providing device 201 and a video receiving device 205, wherein the user of the video providing device 201 can be the initiator of the meeting or the reporter who is presenting a briefing in the meeting, and the user of the video receiving device 205 is other participants, and can be a single participant or multiple participants in different locations, the procedure includes the following steps:

First, the presentation file image picture 22 in the meeting is transmitted to the video receiving device 205 through the network in H.239 format by the video providing device 201; The identification label B21 and the identification label A23 of the video receiving device 205; and according to the operation behavior performed by the user of the video providing device 201 and/or the video receiving device 205, the corresponding information of each conference device is displayed in the image screen by means of dynamic presentation. Identification label.

The preferred embodiment of the present invention utilizes the free definition possibility of the H.245 protocol for control communication, especially for the individual conference devices in the video conference, that is, the video providing device 201 and the video receiving device 205 define corresponding identification tags, so that individual When the conference device is displaying the presentation file image screen 22, the pattern of the identification label can also be dynamically superimposed and displayed in the image screen by means of On Screen Display (hereinafter referred to as OSD).

Please refer to FIG. 2a, which is a schematic diagram of the connection and flow of the identification label presentation system designed by the present invention. The identification label presentation method of the present invention can be applied to a video providing device 201 and a video receiving device 205 connected through a network 203. The network 203 here can be a homogeneous network or a heterogeneous network, and the video receiving device 205 and the video providing device 201 correspond to the identification tag A23 (ie, the first identification tag) and the identification tag B21 (ie, the second identification tag) respectively. tags), and these identification tags can be transmitted using the H.245 protocol that provides user-defined space.

The identification tag presenting method comprises the following steps: first, the video providing device 201 provides an image frame to the video receiving device 205 through the network 203; When the sensing information (first sensing information) sent by the video receiving device 205 is received, the identification tag A23 is dynamically presented in the image frame to represent the status of the corresponding user of the video receiving device 205 .

In addition to dynamically presenting the operation behavior of the user of the video receiving device 205, a similar approach can also be applied to the user's operation behavior of the video providing device 201. By sensing the user's operating behavior of the video providing device 201, the video providing device 201 will send sensing information (second sensing information); and dynamically present the identification label B21 corresponding to the video providing device 201 in the image frame.

Please refer to FIG. 2 b, which is a schematic diagram of the video providing device 201 combining the presentation file image frame 22 with the identification label A23 and the identification label B21 into a composite image frame 24. Here, the video providing device 201 receives information from multiple After receiving the signal from the video receiving device 205, assign the identification tag corresponding to each video receiving device 205, and then add the identification tag and the presentation file image screen 22 through OSD technology and superimpose them into a composite image screen 24, here, corresponding to each conference device The identification label of the conference device may be the default icon of each conference device or a corresponding one assigned by the video providing device 201 .

In addition, the method used to provide the conference briefing document image picture 22 here can be directly provided by the video providing device 201 or provided to the network 203 through another video management device (not shown in the figure), wherein the video management device can It is used to coordinate the resource allocation management during the video conference. In order to increase the speed of transmitting data and image pictures through the network 203 (homogeneous/heterogeneous network) in the video conference, the present invention can further convert, compress or encrypt the pictures operated by the user of the video providing device 201 Complete, so as to reduce the amount of data transmitted by the network 203.

In order to clearly present the features of the present invention, the following description will use an example to illustrate the effects that the present invention can achieve and the architecture designed by the present invention.

Take a video conference held in C, D, and E as an example. The participants in the three places are c, d, and e, respectively, and they are the branches of company F in C, D, and E. The main purpose of the meeting is to discuss the business status of the three branches, and it is assumed that c at location C is the initiator of the meeting or the presenter of the briefing.

Please refer to FIG. 3 a and FIG. 3 b , which are schematic diagrams of image frames displayed in a video conference using the present invention. The line graph 31 in Fig. 3a is a schematic diagram of general sales data. In addition, there are three identification labels 301, 302, and 303 presented in the form of display panes on the right side of the figure. In the identification labels 301, 302, and 303, you can Correspondingly display images of participants c, d, and e or other icons that can be used to identify these three regions/countries. For example, when C, D, and E belong to different countries, the national flags of these three countries can be displayed. or city names etc.

In addition to using the corresponding display pane to represent the identification label to mark the identity of the meeting participants, other methods that can represent the corresponding participants through the screen can also be adopted, such as providing multiple cursors in the screen to correspond to the video provided. All conference devices of the device and video receiving device, or use the color corresponding to individual conference devices to directly emphasize the data in the screen.

When using the conference device provided by the present invention, any participant (for example: c) in the conference can click on the content on the composite image screen through the marking device (usually a remote controller) at hand, and operate in c While the conference signage device or speaking, all participants can see on their respective screens that the display pane of representative c is displayed in a flashing, highlighted or high-brightness manner (as shown in Figure 3a). In addition, In the image screen, a specific color (such as: blue) cursor used to represent c can also be used to indicate the displacement action of c when manually moving the remote control, and even the identification label representing the cursor can also display the operation or speech of each participant at the same time The dynamic or static image of , and/or the icon/name of each region/country (as shown in Figure 3b), so all participants can know the current speaker is c through the dynamic display pane, and by the corresponding Move the cursor of c to understand the content of c's speech.

Of course, when the content of the briefing corresponds to the information of the conference participants in various places, such as the line graphs in this embodiment respectively corresponding to the business conditions of the three branches, the line graphs in the illustration can also be included in one of them. Distinguish the corresponding polyline from the other polylines by emphasizing it when a participant makes a comment. As for the way to display the corresponding relationship, the software can provide relevant option settings, and the user can dynamically decide to use the cursor/dialog box/emphasized broken line to correspond to the participants in different places, and can also use multiple In other words, select the cursor and dialog box at the same time to correspondingly display the same participant, and the settings between the participants are not limited to be consistent.

Please refer to FIG. 4a , which is a schematic diagram of the transmission process of the video providing device 201 of the present invention. When the video providing device 201 starts the transmission process (step S411), it will first divide data types into different formats for processing according to different data types, for example, the presentation content is transmitted in H.239 format (step S412), and the The audio-visual content is encoded by an audio-visual compression format such as H.264 (step S413), and after initializing the color and shape of the cursor and the video frame and controlling the position of the cursor (step S414), the color and shape are transmitted by the H.245 format , address and other related explanatory information (step S415).

After each type of data is prepared according to different formats, then these data contents are encapsulated into H.323 network packet format (step S416), and after being transmitted to the network (step S417), the transmission step of the video providing device 201 is ended ( Step S418).

Please refer to FIG. 4 b , which is a schematic diagram of the receiving process of the video providing device 201 of the present invention. When the video providing device 201 starts to receive the process (step S421), at first it will receive the data packet encapsulated in H.323 format (step S422), and then according to different applications, the data packet of H.323 format will be unpacked and then Decode according to the definition of H.239, H.264, H.245 (steps S423, 424, 425), in addition, also can dynamically detect whether the conference device participating in the meeting has a sound through the network (step S426 ), if there is, the identification label corresponding to the conference device that emits the sound is moved correspondingly and presented in an emphasized manner such as flickering (step S427); if not, the corresponding identification label is displayed in a static manner (step S428) , and finally present the synthesized composite image frame 24 (step S429) and end the receiving process of the video providing device 201 (step S430).

Please refer to FIG. 4c, which is a schematic diagram of the control flow of the video receiving device 205 of the present invention. Different from the general video receiving device 205 which only transmits the audio-visual images of the venue and passively receives the content of the presentation from the video providing device 201 during the meeting, after the video receiving device 205 starts the video conference process (step S431), the video receiving device 205 not only encodes the content of the briefing in H.239 format (step S432), encodes the on-site audio-visual images through H.264 and other audio-visual compression formats (step S433), but also according to the user's manual action or oral expression action, When the user moves the remote control and other marking devices, the corresponding cursor movement information is recorded (step S434), and at the same time, it is sensed whether the user has spoken, and if so, the corresponding sensing information is sent out (step S434), and then After the relevant information is converted into the H.323 packet format (step S435), it is sent to the network together (step S436) and the control process of the video receiving device 205 is ended (step S437).

Here, the identification label used to correspond to the video providing device 201 and the video receiving device 205 can be presented by video, audio or text. The identification tag corresponding to the video receiving device 205 is played by means of dynamic emphasis such as increasing the brightness. Of course, the same method can also be used to display the identification label corresponding to the video providing device 201 when the user of the video providing device 201 sends out a verbal expression action of a voice message or performs an operation in a manual manner.

As for the identification labels corresponding to the video providing device 201 and the video receiving device 205, they can be presented in the form of images, colors or patterns, and the variations of the patterns are quite diverse, whether it is a company logo, a trademark, a department code, a place name, a totem mark or a national flag. Graphics and other patterns that are sufficient to represent the roles of the participants are all feasible, and as far as passing images are concerned, real-time dynamic images can be displayed when users speak, and static images can be displayed for users who do not speak.

In the identification tag presentation system, when the video providing device 201 and the video receiving device 205 connected through the network signal conduct a video conference, the first identification tag and the second identification tag correspond to the video receiving device 205 and the video providing device 201 respectively, wherein The video providing device 201 can transmit the provided image frames operated by the user to the video receiving device 205 through a video management device connected to the network 203 via a signal. The video management device can also be used to sense the individual operation behaviors of the users of the video receiving device 205 and the video providing device 201. Once the user's manual dynamic operation or spoken expression action is sensed, the corresponding identification tags will be dynamically displayed. presented in the image screen.

In order to achieve the above functions, the video providing device 201 in the present invention must transmit the reporter's user's reference picture (such as: a briefing picture or a picture related to the discussion topic, etc.) to the video receiving device 205 of other participants through the network 203 , while the video receiving devices 205 of other participants correspond to different identification tags. As for the details of how the video providing device 201 combines the identification tags and the relevant information of the reference picture and transmits them to the video receiving device 205, it can be determined There are different methods for the allocation of system resources, for example: after the video provider 201 combines the relevant icons of the identification tags with the image screen, the combined image is converted into data information and then sent to the network; or When the user of the conferencing device moves the cursor on the screen, the information such as the coordinate position of the corresponding cursor (that is, the identification label) is sent back to the video provider 201, and then the video provider 201 transmits the individual movement information to all parties through the network. The video receiving device 205.

Please refer to Fig. 5a, which is a schematic diagram of the internal structure of the video providing device 201 applied to the video tag presentation system of the present invention, where the video providing device 201 corresponding to the identification tag B21 (ie, the second identification tag) is signally connected to The video receiving device 205 corresponding to the identification tag A23 (ie, the first identification tag), the video receiving device 205 can send sensing information to the network 203 according to the user's operation behavior.

The video providing device 201 in Fig. 5a comprises: display unit 2011, is used for providing and displaying the image picture of user's reference picture and individual identification tag; The sensing information sent by the video receiving device 205 is received through the network 203, and the display unit 2011 dynamically presents the identification tag A23 corresponding to the video receiving device 205 after receiving the sensing information.

When the display unit 2011 displays the identification tag A23 on the image frame, the purpose of dynamic presentation can be achieved by means of overlapping display. In addition, of course, the video providing device 201 can also use an encoding unit 2015 and electrically connect it to the display unit 2011 to transmit the user's reference picture to the display unit 2011 after converting, compressing or encrypting.

The user’s operation behavior here can be carried out in different ways, such as the user’s oral expression action or manual operation, etc., a detection signal is sent out for the occurrence of the user’s oral expression action, or it is generated according to the user’s manual operation action. Dynamic movement records of marking devices, etc. After the video providing device 201 receives the sensing information sent by the video receiving device 205 through the network, the display unit in the video providing device 201 can dynamically present the image corresponding to the An identification tag A23 of the video receiving device 205 .

As for the actual practice of the sensing unit 2057 in the video receiving device 205, it can be planned according to the needs of the video conferencing system, for example, a voice sensing module is used to sense the spoken language action of the user of the video receiving device 205; module to sense the manual operation action of the user of the video receiving device 205, and record the position movement record in the course of the manual operation action; As for the sensing function of the manual operation action, as for other designs, the composition of the sensing unit 2057 can also be evolved according to the needs of the application.

No matter which structure is adopted, the purpose of the sensing unit 2057 is to send out corresponding sensing information after sensing the user’s actions, and transmit the sensing information to the network 203 and the video providing device 201 through the transmitting and receiving unit 2053 , then the video providing device 201 can be allowed to identify which user of the video receiving device 205 has corresponding interaction during the video conference, and then dynamically present the corresponding identification tag in the image screen.

In the identification label presentation system of the present invention, the positioning of the roles of the video data providing device 201 and the video data receiving device 205 does not need to be limited. After the data report is over, it is shifted to the role of the listener, and the conference device operated by it is also shifted from the video providing device 201 to the video data receiving device 205, so as to receive the meeting briefing data from the next reporter, for example, in In the above-mentioned application, c can change the conference device used by the next speaker d as the new video data providing device 201 after reporting the materials prepared by himself.

In addition, although the present invention uses the common H.323 protocol for video conferencing as the implementation platform for the description of the preferred embodiment, the conceived method and system configuration are not limited to the H.323 protocol. The main core method of video conferencing is to correspond to the participants through multiple pointers or icons on the image screen, and to represent the dynamics of the users of the corresponding conference device in a dynamic way, and to provide participants in the image to identify the speech The sources and actions of the participants allow the video conference to be conducted in a more interactive and communication mode, making the communication of the video conference more efficient.
