Description
本發明是有關於一種視訊會議系統,且特別是有關於一種自動進行訊號源切換判別之視訊畫面智能切換方法及其系統。 The present invention relates to a video conferencing system, and more particularly to a video image intelligent switching method and system thereof for automatically performing signal source switching discrimination.
視訊技術實現了語音、影像、數據等訊號綜合在一起的遠距離傳輸。視訊會議系統由多端控制器(multipoint control unit,MCU)和終端設備組成。每個終端設備對應一個會議室,其中講者所在之會議室的終端設備具有視訊拍攝與發送功能,能拍攝講者會議室的聲音與影像,編碼後發送給多端控制器。多端控制器對聲音與影像進行處理,如聲音混音、影像轉發或組成多畫面等,並將處理後的聲音和影像發送給其他終端設備,由其他終端設備解碼輸出講者會議室的聲音和影像,實現遠端通訊。 Video technology enables long-distance transmission of voice, video, data and other signals together. The video conferencing system consists of a multipoint control unit (MCU) and terminal equipment. Each terminal device corresponds to a conference room, wherein the terminal device of the conference room where the speaker is located has a video capture and transmission function, can capture the sound and image of the speaker conference room, and encodes the code to the multi-end controller. The multi-end controller processes the sound and the image, such as sound mixing, image forwarding or forming a multi-picture, and sends the processed sound and image to other terminal devices, and the other terminal device decodes and outputs the sound of the speaker's conference room and Image for remote communication.
一般視訊會議系統常採用H.323通訊協定,而H.323通訊協定內含H.239通訊協定。其中,H.323通訊協定為用來互傳視訊鏡頭影音之通訊協定,H.239通訊協定為用來互傳簡報內容影音之通訊協定。亦即,一般視訊會議系統具備了可傳視訊鏡頭影音與簡報內容影音之功能。 The general video conferencing system often uses the H.323 protocol, and the H.323 protocol contains the H.239 protocol. Among them, the H.323 communication protocol is a communication protocol for mutually transmitting video and audio and video, and the H.239 communication protocol is a communication protocol for mutually transmitting the content of the presentation. That is to say, the general video conferencing system has the function of transmitting video and video and audio and video content.
然而,有時受到設備或是視訊協定的限制,視訊會議系統會無法同時支援多源訊號流(multi streams)。例如,當系統之中央處理器效能不足,或是網路傳輸頻寬不足時,系統無法即時且同時處理鏡頭訊號流以及簡報影音訊號流。在此狀況下,系統只能在鏡頭訊號流與簡報影音訊號流二選一進行發送。當講者想要分享簡報畫面時,系統是以簡報內容畫面取代原先的鏡頭 影音畫面。反之,若系統選擇傳送鏡頭影音畫面,在終端會議室就無法看到簡報內容畫面。 However, sometimes due to limitations of devices or videoconferencing protocols, video conferencing systems cannot simultaneously support multi-stream streams. For example, when the system's central processor is not efficient or the network transmission bandwidth is insufficient, the system cannot process the lens signal stream and the brief video signal stream instantaneously and simultaneously. In this case, the system can only send one of the lens signal stream and the brief video signal stream. When the speaker wants to share the presentation screen, the system replaces the original lens with the presentation content screen. Audio and video pictures. Conversely, if the system chooses to transmit the lens and video screen, the presentation content screen cannot be seen in the terminal conference room.
亦即,有時在視訊會議中,簡報內容畫面及鏡頭影音畫面只能兩者擇其一傳送。習知方法係使用手動操作控制器進行訊號源的人為切換。具體而言,除了攝影鏡頭、處理簡報的電腦、多端控制器與網路裝置,講者會議室中會另包含一個畫面切換控制器。畫面切換控制器上有一個按鈕,用來手動切換簡報內容畫面及鏡頭影音畫面,講者需在兩者擇其一傳送。例如當講者想要分享會議室內的畫面時,需要通過遙控器發出會議控制訊號,向MCU申請發送會議室的影音,MCU在接收到控制器發來的的控制訊號後,將會議室的鏡頭影音訊號轉發至其他終端設備,這樣完成一次畫面切換。 That is to say, sometimes in a video conference, the presentation content screen and the lens audio and video screen can only be transmitted one by one. The conventional method uses a manually operated controller for manual switching of the signal source. Specifically, in addition to the photographic lens, the computer that processes the briefing, the multi-terminal controller, and the network device, a speaker switching controller is additionally included in the speaker conference room. There is a button on the screen switching controller for manually switching the presentation content screen and the lens video screen. The speaker needs to transmit one of the two. For example, when the speaker wants to share the screen in the conference room, the conference control signal needs to be sent through the remote controller, and the MCU is requested to send the video and audio of the conference room. After receiving the control signal sent by the controller, the MCU will take the conference room lens. The audio and video signals are forwarded to other terminal devices, thus completing a screen switch.
因此,講者在進行視訊會議時,同時須注意所傳送之鏡頭畫面呈現,再搭配以手動操作控制器切換簡報內容畫面輸出,使用上極不方便。習知手動操作控制器的切換方法容易導致講者分心或停滯,或者因錯誤的切換而導致與會者錯失會議的重要資訊。 Therefore, when the speaker is conducting a video conference, it is necessary to pay attention to the presentation of the transmitted lens screen, and then use the manual operation controller to switch the presentation content screen output, which is inconvenient to use. Conventional manual operation controller switching methods are prone to distraction or stagnation of the speaker, or the attendees miss the important information of the conference due to the wrong switching.
為了保障視訊會議的連續性,並能夠即時地切換影音畫面,本發明實施例提供了一種視訊畫面智能切換方法及其系統。 In order to ensure the continuity of the video conference and to switch the video and audio images in real time, the embodiment of the invention provides a method and system for intelligently switching video images.

Firstly, the video screen intelligent switching system is activated, including a shooting module for shooting the conference room audio and a presentation playing module for playing the digital presentation. Then, the video conference connection command is started, so that the video screen intelligent switching system selects and outputs the conference room video and audio. Thereafter, the briefing sharing instruction is started, so that the video screen intelligent switching system selects and outputs the digital briefing. When the real-time status of the digital presentation changes, the video screen intelligent switching system automatically selects and outputs the digital presentation. When the real-time status of the digital briefing has not changed after the preset time, the video screen intelligent switching system automatically selects and outputs the conference room video and audio.
根據上述目的,本發明提供一種視訊畫面智能切換 系統,包括攝影模組、簡報播放模組、簡報辨識模組與輸出控制模組。攝影模組用於拍攝會議室影音。簡報播放模組用於播放數位簡報。簡報辨識模組用於檢測數位簡報之即時狀態。輸出控制模組用於選擇輸出會議室影音與輸出數位簡報兩者其中之一。當簡報辨識模組檢測到數位簡報之即時狀態有變動時,簡報辨識模組傳送輸出簡報訊號至輸出控制模組,使輸出控制模組選擇輸出數位簡報。當簡報辨識模組檢測到數位簡報之即時狀態經過預設時間均無變動時,簡報辨識模組傳送輸出攝影訊號至輸出控制模組,使輸出控制模組選擇輸出會議室影音。 According to the above object, the present invention provides an intelligent switching of video images. The system includes a photography module, a presentation playing module, a briefing recognition module and an output control module.

The briefing recognition module is used to detect the immediate status of the digital presentation. The output control module is used to select one of the output conference room video and the output digital presentation. When the briefing recognition module detects that the real-time status of the digital briefing changes, the briefing identification module transmits the output briefing signal to the output control module, so that the output control module selects and outputs the digital briefing. When the instant messaging module detects that the instant state of the digital briefing has not changed after the preset time, the briefing identification module transmits and outputs the output photography signal to the output control module, so that the output control module selects and outputs the conference room video and audio.
通過檢測數位簡報之即時狀態,當使用數位簡報時,在不需要講者額外指令的情況下,無須中控系統人為操作,就能將視訊傳輸畫面自動切換到數位簡報。此外,當數位簡報閒置一段預設時間未使用時,系統會將視訊傳輸畫面自動切換到會議室影音,保障了視訊會議的連續性,並能夠即時地切換影音畫面,提升了視訊會議中資訊分享的正確性。 By detecting the real-time status of the digital presentation, when the digital presentation is used, the video transmission screen can be automatically switched to the digital presentation without the need for the operator to perform the manual operation without the need for the operator's additional instructions. In addition, when the digital presentation is idle for a preset period of time, the system will automatically switch the video transmission screen to the conference room audio and video, which ensures the continuity of the video conference, and can instantly switch the video and audio images to enhance the information sharing in the video conference. The correctness.

It must be understood that the present invention provides a number of applicable innovative concepts that can be widely implemented under specific background art. This particular embodiment is shown by way of example only, and is not intended to limit the scope of the invention.
第1圖係表示本發明第一實施例視訊畫面智能切換系統100之模組示意圖;第2圖係表示本發明第一實施例視訊畫面智能切換系統100之運作示意圖。如第1圖所示,視訊畫面智能切換系統100包括攝影模組110、簡報播放模組120、簡報辨識模組130、輸出控制模組140、語音辨識模組150與動作辨識模組160。 1 is a block diagram showing a video screen intelligent switching system 100 according to a first embodiment of the present invention; and FIG. 2 is a schematic diagram showing the operation of the video screen intelligent switching system 100 according to the first embodiment of the present invention. As shown in FIG. 1 , the video screen intelligent switching system 100 includes a camera module 110 , a presentation module 120 , a briefing module 130 , an output control module 140 , a voice recognition module 150 , and a motion recognition module 160 .
如第1圖與第2圖所示,攝影模組110用於拍攝會議室影音102。此處會議室影音102包括會議室影像訊號與會議室語音訊號,例如是講者106的影像與語音,或是包括講者106影音與黑板或白板的影像。攝影模組110可包括語音接受單元152與動作接收單元162,例如包括一組麥克風與一組視訊鏡頭。語音接受單元152用於接收講者106語音訊號,動作接收單元162用於接收講者106動作訊號。 As shown in FIGS. 1 and 2, the photographing module 110 is used to photograph the conference room video 102. The conference room video 102 includes a conference room video signal and a conference room voice signal, such as the image and voice of the speaker 106, or an image including the speaker 106 video and the blackboard or the whiteboard. The photography module 110 can include a voice accepting unit 152 and an action receiving unit 162, for example, including a set of microphones and a set of video lenses. The voice accepting unit 152 is configured to receive the speaker 106 voice signal, and the action receiving unit 162 is configured to receive the speaker 106 motion signal.
簡報播放模組120例如為筆記型電腦之應用程式,用於播放數位簡報104。數位簡報104播放時之即時狀態可包括即時簡報畫面、簡報操作輸入指令與簡報輸出音訊。其中,簡報操作輸入指令可包括鍵盤操作訊號、滑鼠操作訊號或觸控板操作訊號。輸出控制模組140用於選擇輸出會議室影音102與輸出數位簡報104兩者其中之一,例如可為MCU。 The presentation play module 120 is, for example, an application for a notebook computer for playing a digital presentation 104. The instant status of the digital presentation 104 during playback may include an instant presentation screen, a presentation operation input command, and a presentation output audio. The briefing operation input command may include a keyboard operation signal, a mouse operation signal or a touchpad operation signal. The output control module 140 is configured to select one of the output conference room video 102 and the output digital presentation 104, such as an MCU.
簡報辨識模組130用於檢測數位簡報104播放時之即時狀態。詳言簡報辨識模組130之內容,簡報辨識模組130可包括簡報畫面偵測單元132、簡報操作偵測單元134與簡報輸出偵測單元136,用於檢測數位簡報104之即時狀態是否有變動。當視訊畫面智能切換系統100檢測出即時簡報畫面有變動時,或偵測到簡報操作輸入指令或簡報輸出音訊時,判斷為即時狀態有變動。 The briefing recognition module 130 is configured to detect the immediate state of the digital presentation 104 during playback. For example, the briefing module 130 can include a briefing screen detecting unit 132, a briefing operation detecting unit 134, and a briefing output detecting unit 136 for detecting whether the real-time status of the digital presentation 104 is changed. . When the video screen intelligent switching system 100 detects that there is a change in the instant briefing screen, or detects a briefing operation input command or a briefing output audio, it is determined that the instantaneous state has changed.
具體而言,當簡報畫面偵測單元132檢測到即時簡報畫面有變動,或是當簡報操作偵測單元134偵測到簡報操作輸入指令,或是當簡報輸出偵測單元136偵測到簡報輸出音訊時,簡報辨識模組130即判斷為即時狀態有變動,簡報辨識模組130傳送輸出簡報訊號至輸出控制模組140,進而使輸出控制模組140選擇將視訊分享畫面切換為數位簡報104。例如,當講者106或其他使用者 按壓筆記型電腦鍵盤、移動電腦滑鼠、敲擊滑鼠按鍵或操作觸控板時,輸出控制模組140會將分享畫面切換為數位簡報104。亦即,當簡報辨識模組130檢測到數位簡報104之即時狀態有變動時,輸出控制模組140選擇輸出數位簡報104。 Specifically, when the briefing screen detecting unit 132 detects that the instant briefing screen has changed, or when the briefing operation detecting unit 134 detects the briefing operation input instruction, or when the briefing output detecting unit 136 detects the briefing output. During the audio, the briefing recognition module 130 determines that the real-time status changes, and the briefing recognition module 130 transmits the output briefing signal to the output control module 140, thereby causing the output control module 140 to switch the video sharing screen to the digital presentation 104. For example, when the speaker 106 or other user When the notebook keyboard is pressed, the computer mouse is moved, the mouse button is pressed, or the touch panel is operated, the output control module 140 switches the sharing screen to the digital presentation 104. That is, when the briefing recognition module 130 detects that there is a change in the real-time status of the digital presentation 104, the output control module 140 selects to output the digital presentation 104.
反之,當簡報辨識模組130檢測到數位簡報104之即時狀態經過預設時間均無變動時,簡報辨識模組130傳送輸出攝影訊號至輸出控制模組140,使輸出控制模組140選擇輸出會議室影音102。 On the other hand, when the briefing recognition module 130 detects that the instant state of the digital briefing 104 has not changed for a preset time, the briefing recognition module 130 transmits and outputs the output photography signal to the output control module 140, so that the output control module 140 selects the output conference. Room audio 102.
據此,本發明之簡報辨識模組130與輸出控制模組140可根據簡報播放狀態自動且即時地切換影音畫面,保障視訊會議的連續性與正確性。 Accordingly, the briefing recognition module 130 and the output control module 140 of the present invention can automatically and instantly switch the video and audio images according to the briefing playing state, thereby ensuring the continuity and correctness of the video conferencing.
除了藉由系統判斷自動進行視訊畫面的切換,本發明亦可根據講者106的動作或語音指令來進行視訊畫面的切換。語音辨識模組150用於判斷會議室語音訊號是否在呼喚數位簡報104或會議室影音102。語音辨識模組150中可以預先存儲幾組切換預設指令,此指令可以是由系統預存,也可以是由使用者自行設定。例如,預存「切換簡報」語音指令,以將視訊分享畫面切換為數位簡報104,而預存「切換會議室」語音指令,以將視訊分享畫面切換為會議室影音102。 In addition to automatically switching the video screen by the system, the present invention can also switch the video screen according to the action of the speaker 106 or the voice command. The voice recognition module 150 is configured to determine whether the conference room voice signal is calling the digital presentation 104 or the conference room video 102. The voice recognition module 150 may pre-store several sets of switching preset commands, which may be pre-stored by the system or set by the user. For example, the "switching briefing" voice command is pre-stored to switch the video sharing screen to the digital presentation 104, and the "switching conference room" voice command is pre-stored to switch the video sharing screen to the conference room video 102.
視訊會議進行時,語音接受單元152持續接收講者106語音訊號,當語音辨識模組150判斷出會議室語音訊號是在呼喚數位簡報104時,例如講者106喊出「切換簡報」語句,語音辨識模組150辨識出此語句符合預先存儲的切換指令,接著語音辨識模組150傳送輸出簡報訊號至輸出控制模組140,使輸出控制模組140選擇輸出數位簡報104,完成一次的視訊畫面切換。同理,當語音辨識模組150判斷會議室語音訊號是在呼喚會議室影音102時,例如講者106喊出「切換會議室」語句,攝影模組110接收到此會議室語音訊號,語音辨識模組150辨識出此語句符合預先存儲的切換指令,接著語音辨識模組150傳送輸出攝影訊號至輸出控制模組140,使輸出控制模組140選擇輸出會議室影音102。 During the video conference, the voice accepting unit 152 continuously receives the voice signal of the speaker 106. When the voice recognition module 150 determines that the conference room voice signal is calling the digital briefing 104, for example, the speaker 106 utters a "switching briefing" statement, voice. The recognition module 150 recognizes that the statement meets the pre-stored switching instruction, and then the voice recognition module 150 transmits the output summary signal to the output control module 140, so that the output control module 140 selects and outputs the digital presentation 104 to complete the video screen switching. . Similarly, when the voice recognition module 150 determines that the conference room voice signal is calling the conference room video 102, for example, the speaker 106 calls the "switch conference room" statement, and the camera module 110 receives the conference room voice signal and voice recognition. The module 150 recognizes that the statement conforms to the pre-stored switching command, and then the voice recognition module 150 transmits the output camera signal to the output control module 140, so that the output control module 140 selects and outputs the conference room video 102.
動作辨識模組160用於判斷講者106動作訊號是在呼喚數位簡報104或會議室影音102。動作辨識模組160中亦可預先存儲幾組切換預設指令。例如,預存「順時針畫圈」動作指令,以將視訊分享畫面切換為數位簡報104,而預存「逆時針畫圈」」動作指令,以將視訊分享畫面切換為會議室影音102。 The action recognition module 160 is configured to determine whether the speaker 106 action signal is calling the digital presentation 104 or the conference room video 102. The set of switching preset commands may also be pre-stored in the motion recognition module 160. For example, the "clockwise circle" action command is pre-stored to switch the video sharing screen to the digital presentation 104, and the "counterclockwise circle" action command is pre-stored to switch the video sharing screen to the conference room video 102.
視訊會議進行時,動作接收單元162持續接收講者106動作訊號,當動作辨識模組160判斷講者106動作訊號是在呼喚數位簡報104時,例如講者106以手比劃「順時針畫圈」動作,動作辨識模組160辨識出此動作符合預先存儲的切換指令,接著動作辨識模組160傳送輸出簡報訊號至輸出控制模組140,使輸出控制模組140選擇輸出數位簡報104,完成一次的視訊畫面切換。同理,當動作辨識模組160判斷講者106動作訊號是在呼喚會議室影音102時,使輸出控制模組140選擇輸出會議室影音102。 When the video conference is in progress, the action receiving unit 162 continuously receives the speaker 106 action signal. When the action recognition module 160 determines that the speaker 106 action signal is calling the digital briefing 104, for example, the speaker 106 uses the hand to draw a "clockwise circle". The action recognition module 160 recognizes that the action conforms to the pre-stored switching command, and then the action recognition module 160 transmits the output summary signal to the output control module 140, so that the output control module 140 selects and outputs the digital presentation 104, once completed. Video screen switching. Similarly, when the motion recognition module 160 determines that the speaker 106 motion signal is calling the conference room video 102, the output control module 140 selects and outputs the conference room video 102.
當數位簡報104被關閉時,輸出控制模組140只需要輸出會議室影音102,視訊畫面智能切換系統100不需要再選擇輸出數位簡報104,因此可關閉簡報辨識模組130之檢測,減少系統的工作量。 When the digital presentation 104 is turned off, the output control module 140 only needs to output the conference room video 102. The video screen intelligent switching system 100 does not need to select the output digital presentation 104, so the detection of the briefing identification module 130 can be turned off, and the system is reduced. The amount of work.
據此,本發明之視訊畫面智能切換系統100可根據簡報播放狀態自動且即時地切換影音畫面,保障視訊會議的連續性與正確性。此外,本發明可根據講者106的動作或語音指令來進行視訊畫面的切換,使會議進行更為流暢。 Accordingly, the video picture intelligent switching system 100 of the present invention can automatically and instantly switch the video and audio pictures according to the presentation playing status, thereby ensuring the continuity and correctness of the video meeting. In addition, the present invention can switch the video screen according to the action or voice command of the speaker 106, so that the conference is smoother.
以下將用前述視訊畫面智能切換系統100為基礎,介紹視訊畫面智能切換方法。第3圖係表示本發明第一實施例視訊畫面智能切換方法之流程示意圖,並請一併參考第1圖與第2圖。如第1圖至第3圖所示,首先,步驟210係啟動前述之視訊畫面智能切換系統100,以便進行視訊會議。接著,步驟212啟動視訊會議連線指令。連線時,攝影模組110會持續拍攝會議室影音102,此時輸出控制模組140選擇輸出會議室影音102。 The video screen intelligent switching system 100 will be described below based on the aforementioned video screen intelligent switching system 100. FIG. 3 is a schematic flow chart showing a method for intelligently switching a video screen according to the first embodiment of the present invention, and please refer to FIG. 1 and FIG. 2 together. As shown in FIGS. 1 to 3, first, step 210 activates the aforementioned video screen intelligent switching system 100 for video conferencing. Next, step 212 initiates a video conference connection command. When connected, the camera module 110 continuously captures the conference room video 102, and the output control module 140 selects to output the conference room video 102.
其後,步驟214啟動簡報分享指令,此時簡報播放模組120開始播放數位簡報104。如步驟220所示,輸出控制模組140 選擇持續輸出數位簡報104,此時分享的視訊畫面為數位簡報104。如步驟222所示,啟動簡報分享指令後,簡報辨識模組130會持續檢測數位簡報104之即時狀態是否有變動。 Thereafter, step 214 initiates a briefing sharing instruction, at which point the presentation playing module 120 begins playing the digital presentation 104. As shown in step 220, the output control module 140 The continuous selection digital presentation 104 is selected, and the shared video screen is a digital presentation 104. As shown in step 222, after the briefing sharing instruction is initiated, the briefing recognition module 130 continuously detects whether the instant status of the digital presentation 104 has changed.
如步驟224所示,在視訊畫面為數位簡報104的狀況下,若數位簡報104之即時狀態在預設時間內有變動時,例如3分鐘內有變動,輸出控制模組140判斷為使用者正在使用簡報。輸出控制模組140決策維持現狀,即繼續停留於簡報畫面,輸出數位簡報104。若視訊畫面輸出為數位簡報104,則本方法會重複步驟220與步驟222進行檢測。 As shown in step 224, in the case where the video screen is the digital presentation 104, if the immediate status of the digital presentation 104 changes within a preset time, for example, within 3 minutes, the output control module 140 determines that the user is Use the newsletter. The output control module 140 decides to maintain the status quo, that is, continues to stay on the briefing screen and outputs the digital presentation 104. If the video screen is output as the digital presentation 104, the method repeats steps 220 and 222 for detection.
如步驟226所示,如果數位簡報104之即時狀態經過一段預設時間均無變動時,例如經過3分鐘均無變動,輸出控制模組140會自動切換成輸出會議室影音102。如步驟240所示,輸出控制模組140持續輸出會議室影音102,此時分享的視訊畫面為會議室影音102。如步驟242所示,在視訊會議畫面切換為會議室影音102後,簡報辨識模組130仍會持續檢測數位簡報104之即時狀態。 As shown in step 226, if the instant state of the digital presentation 104 has not changed for a predetermined period of time, for example, no change after 3 minutes, the output control module 140 automatically switches to output the conference room video 102. As shown in step 240, the output control module 140 continuously outputs the conference room video 102, and the shared video screen is the conference room video 102. As shown in step 242, after the video conference screen is switched to the conference room video 102, the briefing recognition module 130 continues to detect the instant status of the digital presentation 104.
如步驟244所示,在視訊畫面為會議室影音102的狀況下(接續步驟242),如果數位簡報104之即時狀態無變動時,輸出控制模組140會維持輸出會議室影音102。亦即,若視訊畫面輸出為會議室影音102,則本方法會重複步驟240與步驟242進行檢測。 As shown in step 244, in the case where the video screen is the conference room video 102 (continued to step 242), if the instant state of the digital presentation 104 does not change, the output control module 140 maintains the output conference room video 102. That is, if the video screen output is the conference room video 102, the method repeats steps 240 and 242 for detection.
回到步驟240與步驟242,在視訊畫面為會議室影音102的狀況下,若數位簡報104之即時狀態有變動時,輸出控制模組140判斷為使用者正在使用簡報。如步驟246所示,輸出控制模組140切換為輸出數位簡報104。 Returning to step 240 and step 242, if the video device is in the conference room video 102, if the real-time status of the digital presentation 104 changes, the output control module 140 determines that the user is using the briefing. As shown in step 246, the output control module 140 switches to output the digital presentation 104.
