Description

辨識視訊訊號來源的方法 Method to identify the source of video signal

本發明是有關於一種辨識視訊訊號來源的方法。 The invention relates to a method for identifying the source of a video signal.

傳統上，當簡報人員欲操作資訊處理裝置(例如筆記型電腦)透過顯示裝置進行簡報時，必需利用視訊訊號線(例如HDMI視訊傳輸線)連接資訊處理裝置與顯示裝置(例如投影機或大尺寸電視)，才能把資訊處理裝置輸出的簡報影像資料傳送到顯示裝置，進而顯示簡報影像資料。但如此以有線視訊訊號線連接資訊處理裝置與顯示裝置進行簡報方式，使用上有諸多限制，例如當在會議中要切換顯示儲存在不同資訊處理裝置中的簡報資料時，簡報者必需先自原本資訊處理裝置移除視訊訊號線，然後再把視訊訊號線連接到另一台資訊處理裝置上，如此往往造成會議議程中斷。 Traditionally, when a presenter wants to operate an information processing device (such as a laptop) for presentation through a display device, it is necessary to use a video signal cable (such as an HDMI video transmission cable) to connect the information processing device and a display device (such as a projector or a large-size TV). ) In order to transmit the presentation image data output by the information processing device to the display device, and then display the presentation image data. However, there are many restrictions on the way of using a wired video signal cable to connect the information processing device and the display device for presentation. For example, when switching to display presentation data stored in different information processing devices in a meeting, the presenter must start from the original The information processing device removes the video signal cable, and then connects the video signal cable to another information processing device, which often causes the meeting agenda to be interrupted.

針對上述操作不便處，目前市面上出現多人無線簡報系統產品；此種多人無線簡報系統產品，一般包含多個傳送端裝置和單一個接收端裝置。每位參與會議成員可將一個傳送端裝置連接到自己資訊處理裝置的視訊輸出埠，而接收端裝置則是連接在顯示裝置的視訊輸入埠上。當只有一位簡報者按壓傳送端裝置上的投影按鈕時，此 些傳送端裝置其中之一會與接收端裝置進行無線的影像資料傳輸，而顯示裝置只會顯示單一台資訊處理裝置輸出的影像資料。但是當有多位簡報者按壓傳送端裝置上的投影按鈕時，此些傳送端裝置其中會有多個與接收端裝置進行無線的影像資料傳輸，而顯示裝置會以分割畫面方式顯示多台資訊處理裝置輸出的影像資料。但在分割畫面方式顯示狀態下，對於參與會議成員容易造成混淆，參加會議者無法辨識目前顯示裝置分割畫面中各個視訊訊號來源究竟是哪一位簡報者的資訊處理裝置。因此當參加會議者要針對分割畫面中某個畫面有疑問時，必需額外詢問確認此畫面是誰的簡報資料，才能向相關簡報者提出問題討論。 In view of the aforementioned operational inconveniences, multi-person wireless presentation system products are currently available on the market; such multi-person wireless presentation system products generally include multiple transmitting end devices and a single receiving end device. Each participant in the conference can connect a sender device to the video output port of their own information processing device, and the receiver device is connected to the video input port of the display device. When only one presenter presses the projection button on the sending device, this One of the sending end devices will perform wireless image data transmission with the receiving end device, and the display device will only display the image data output by a single information processing device. However, when multiple presenters press the projection button on the sending end device, several of these sending end devices will wirelessly transmit image data with the receiving end device, and the display device will display the information of multiple stations in a split screen manner. Process the image data output by the device. However, in the split-screen display state, it is easy to cause confusion for the participants in the conference, and the participants in the conference cannot identify which presenter’s information processing device is the source of each video signal in the split screen of the current display device. Therefore, when participants in the conference have questions about a certain screen in the split screen, they must additionally ask to confirm whose presentation data the screen is, in order to raise questions to the relevant presenters for discussion.

In addition, in step 204, after the receiving end device 320 and the first sending end device 310 are connected to power, the user can press the pairing button on the receiving end device 320 and the first sending end device 310, and then both parties will try to establish a connection. line. When a connection is established between the first transmission module 314 in the first transmitting end device 310 and the second transmission module 322 in the receiving end device 320, then In step 206, the receiving end device 320 and the first sending end device 310 will interact with each other to update internal information. The receiving end device 320 will also record the order in which the first sending end device 310 establishes a connection, and assign the corresponding color identification. Code to the transmitting end device. The first transmitting end control unit 312 and the receiving end control unit 324 both preset to store a list of identification codes corresponding to the color of the light. For example, the first transmitting end device that successfully establishes a connection with the receiving end device 320 is scheduled to be assigned as an identification Code #1, its corresponding first identification image is red, the second successfully connected transmitter device is scheduled to be assigned as identification code #2, and its corresponding second identification image is green... and so on . In this way, when the first transmitting-end device 310 is the first transmitting-end device to establish a connection, the receiving-end control unit 324 will record that the first transmitting-end device 310 is the first in order to establish a connection, and assign the identification code #1 to the first transmitting-end device 310. A transmitting end device 310. Similarly, when the second transmitting end device 330 is connected to power later and becomes the second transmitting end device that successfully establishes a connection with the receiving end device 320, the receiving end control unit 324 will record that the second transmitting end device 330 is the first The connection is established in the second order, and the identification code #2 is assigned to the second transmitting end device 330. The receiving end control unit 324 can know that the first identification image corresponding to the identification code #1 is red, and the second identification image corresponding to the identification code #2 by referring to the preset stored list of identification codes corresponding to the color of the light. It's green. In this embodiment, the first recognition image and the second recognition image are illustrated by taking red and green as examples, but it is not limited to this. The first recognition image and the second recognition image can also be Arabic numerals "1". "And "2", or the English letters "A" and "B".

對應於步驟104，詳細步驟包括第2圖所示步驟208。於步驟208中，判斷傳送端裝置是否把視訊資料傳送給接收端裝置320？若是，則執行步驟210。當第一傳送端裝置310的第一傳輸模組314與接收端裝置320的第二傳輸模組322建立連線，但第一使用者尚未按壓第 一傳送端裝置310上的投影按鈕時，第一傳送端裝置310並未把第一視訊資料Vid1傳送給接收端裝置320。當第一使用者按壓第一傳送端裝置310上的投影按鈕後，第一傳送端裝置310開始把第一視訊資料Vid1傳送給接收端裝置320，如此滿足步驟208，則執行步驟210。以此類推，當第二傳送端裝置330的第三傳輸模組334與接收端裝置320的第二傳輸模組322建立連線，當第二使用者按壓第二傳送端裝置330上的投影按鈕後，第二傳送端裝置330開始把第二視訊資料Vid2傳送給接收端裝置320。 Corresponding to step 104, the detailed steps include step 208 shown in Figure 2. In step 208, it is determined whether the transmitting end device transmits the video data to the receiving end device 320? If yes, go to step 210. When a connection is established between the first transmission module 314 of the first transmitting end device 310 and the second transmission module 322 of the receiving end device 320, but the first user has not yet pressed the When a projection button on the transmitting end device 310 is used, the first transmitting end device 310 does not transmit the first video data Vid1 to the receiving end device 320. When the first user presses the projection button on the first sending end device 310, the first sending end device 310 starts to transmit the first video data Vid1 to the receiving end device 320, and if step 208 is satisfied, step 210 is executed. By analogy, when the third transmission module 334 of the second transmitter device 330 establishes a connection with the second transmission module 322 of the receiver device 320, when the second user presses the projection button on the second transmitter device 330 After that, the second transmitting end device 330 starts to transmit the second video data Vid2 to the receiving end device 320.

如第2圖所示，本實施例之辨識視訊訊號來源的方法可選擇性地包含步驟209，判斷是否超過1個傳送端裝置傳送視訊資料給接收端裝置320？若是則執行步驟210，若否則跳過步驟210。步驟209針對如下情境，接收端控制單元324可以動態關閉接收端控制單元內的視訊合成電路，動態地降低接收端控制單元324的電能消耗，達成省電效果。步驟209適用情境是：雖然第一傳送端裝置310和第二傳送端裝置330均已經與接收端裝置320建立連線，(1)當只有第一傳送端裝置310正在傳送第一視訊資料Vid1給接收端裝置320，顯示裝置360整個畫面都在顯示第一視訊資料Vid1時，參與會議者能夠很清楚地理解到目前是操作第一傳送端裝置310的簡報者正在輸出第一視訊資料Vid1，如此接收端控制單元324可以省略在顯示裝置360中顯示識別碼對應的顏色，例如接收端控制單元324可以關閉接收端控制單元324內的視訊合成電路，跳過步驟210，來降低接收端控制單元324的電能消耗。(2)當第一傳送端裝置310傳送第一視訊資料Vid1給接收端裝置， 且同時第二傳送端裝置330傳送第二視訊資料Vid2給接收端裝置320時，顯示裝置360以分割畫面方式同時顯示第一視訊資料Vid1和第二視訊資料Vid2時，參與會議者此時無法清楚辨識視訊訊號時，此時接收端控制單元324才需要在顯示裝置360中顯示識別碼對應的顏色，例如接收端控制單元324此時才啟動接收端控制單元324內的視訊合成電路，執行步驟210。 As shown in Figure 2, the method for identifying the source of a video signal of this embodiment can optionally include step 209, determining whether more than one transmitting end device transmits video data to the receiving end device 320? If yes, go to step 210, if not, skip step 210. Step 209 is aimed at the following scenario, the receiving end control unit 324 can dynamically turn off the video synthesis circuit in the receiving end control unit, dynamically reducing the power consumption of the receiving end control unit 324, and achieving a power saving effect. The applicable scenario of step 209 is: although both the first sending end device 310 and the second sending end device 330 have established a connection with the receiving end device 320, (1) when only the first sending end device 310 is sending the first video data Vid1 to When the entire screen of the receiving device 320 and the display device 360 is displaying the first video data Vid1, the participants in the conference can clearly understand that the presenter who is currently operating the first transmitting device 310 is outputting the first video data Vid1, so The receiving end control unit 324 can omit displaying the color corresponding to the identification code in the display device 360. For example, the receiving end control unit 324 can turn off the video synthesis circuit in the receiving end control unit 324 and skip step 210 to lower the receiving end control unit 324. Power consumption. (2) When the first transmitting end device 310 transmits the first video data Vid1 to the receiving end device, At the same time, when the second transmitting end device 330 transmits the second video data Vid2 to the receiving end device 320, when the display device 360 simultaneously displays the first video data Vid1 and the second video data Vid2 in a split-screen manner, the participants cannot understand at this time. When recognizing the video signal, the receiving end control unit 324 only needs to display the color corresponding to the identification code in the display device 360 at this time. For example, the receiving end control unit 324 activates the video synthesis circuit in the receiving end control unit 324 at this time, and executes step 210. .

對應於步驟106~108，詳細步驟包括第2圖所示步驟210：接收端裝置320依照分配給傳送端裝置的識別碼，在顯示裝置360中顯示識別碼對應的顏色，且傳送端裝置指示燈顯示識別碼對應的顏色。當第一傳送端裝置310傳送第一視訊資料Vid1給第二傳輸模組322時，接收端控制單元324將第一視訊資料Vid1與第一識別圖像(例如紅色識別圖像)合成第一合成視訊資料Vid_C1，並將第一合成視訊資料Vid_C1輸出至顯示裝置360。當第一合成視訊資料Vid_C1顯示在顯示裝置360中時，如第4A圖所示，第一合成視訊資料Vid_C1對應於第一視訊區域462與第一識別區域464，第一視訊區域462鄰近第一識別區域464，第一視訊區域462顯示第一視訊資料Vid1，第一識別區域464顯示第一識別圖像。接收端控制單元324發出提示指令要求第一傳送端裝置310之第一指示裝置316顯示第一識別圖像。於本實施例中，接收端控制單元324將第一視訊資料Vid1與紅色識別圖像合成第一合成視訊資料Vid_C1，使在顯示裝置360中顯示對應的紅色識別圖像，且使第一傳送端裝置310上的指示燈顯示識別碼#1所對應的紅色。以此類推，接收端控制單元324將第二視訊資料Vid2與綠色識別圖像合成第二合成視訊資料Vid_C2，並將第二合成視訊資料Vid_C2輸出至顯 示裝置360，使在顯示裝置360中顯示對應的綠色識別圖像，且使第二傳送端裝置330上的第二指示裝置336(例如指示燈)顯示識別碼#2所對應的綠色。 Corresponding to steps 106 to 108, the detailed steps include step 210 shown in Figure 2: The receiving end device 320 displays the color corresponding to the identification code on the display device 360 according to the identification code assigned to the transmitting end device, and the indicator light of the transmitting end device The color corresponding to the identification code is displayed. When the first transmitting end device 310 transmits the first video data Vid1 to the second transmission module 322, the receiving end control unit 324 combines the first video data Vid1 and the first identification image (for example, the red identification image) into a first composite The video data Vid_C1 is output, and the first synthesized video data Vid_C1 is output to the display device 360. When the first synthesized video data Vid_C1 is displayed in the display device 360, as shown in FIG. 4A, the first synthesized video data Vid_C1 corresponds to the first video area 462 and the first identification area 464, and the first video area 462 is adjacent to the first The recognition area 464, the first video area 462 displays the first video data Vid1, and the first recognition area 464 displays the first recognition image. The receiving end control unit 324 issues a prompt command to request the first indicating device 316 of the first transmitting end device 310 to display the first recognition image. In this embodiment, the receiving end control unit 324 synthesizes the first video data Vid1 and the red identification image into the first composite video data Vid_C1, so that the corresponding red identification image is displayed on the display device 360, and the first transmitting end The indicator light on the device 310 displays red corresponding to the identification code #1. By analogy, the receiving end control unit 324 synthesizes the second video data Vid2 and the green identification image into the second synthesized video data Vid_C2, and outputs the second synthesized video data Vid_C2 to the display. The display device 360 causes the corresponding green identification image to be displayed on the display device 360, and causes the second indicating device 336 (such as an indicator light) on the second transmitting end device 330 to display the green color corresponding to the identification code #2.

如第第11圖所示，於步驟1104中，接收端控制單元1224通知第一傳送端控制單元1212將第一視訊資料Vid1與第一識別圖像合成第一合成視訊資料Vid_C1。當第一傳送端裝置1210中的第一傳輸模組1214與接收端裝置1220中的第二傳輸模組1222建立連線後，接收端裝置1220和第一傳送端裝置1210會彼此交互更新內部資訊，第一傳送端裝置1210傳送第一識別碼給接收端裝置1220內的接收端控制單元1224。第一傳送端控制單元1212與接收端控制單元1224雙方內部均預設儲存識別碼對應燈號顏色的列表，例如第一傳送端裝置1210出廠時被設定分配到識別碼#1，其對應的第一識別圖像是紅色，第二傳送端裝置1230出廠時被設定分配到識別碼#2，其對應的第二識別圖像是綠色，以此類推。如此當第一傳送端裝置1210和接收端裝置1220建立連線時，接收端控制單元1224會記錄第一傳送端裝置1210具有識別碼#1。類似地，當稍後第二傳送端裝置1230和接收端裝置1220建立連線時，接收端控制單元1224會記錄第二傳送端裝置1230具有識別碼#2。接收端控制單元1224經由查閱內部所預設儲存的識別碼對應燈號顏色的列表，可以得知識別碼#1對應的第一識別圖像是紅色，識別碼#2對應的第二識別圖像是綠色。於本實施例中，第一識別圖像與第二識別圖像係分別以紅色與綠色為 例說明，然不限於此，第一識別圖像與第二識別圖像也可分別是***數字「1」與「2」，或是英文字母「A」與「B」。 As shown in FIG. 11, in step 1104, the receiving end control unit 1224 notifies the first transmitting end control unit 1212 to synthesize the first composite video data Vid_C1 with the first video data Vid1 and the first identification image. When a connection is established between the first transmission module 1214 in the first transmitting end device 1210 and the second transmission module 1222 in the receiving end device 1220, the receiving end device 1220 and the first transmitting end device 1210 will interact with each other to update internal information , The first transmitting end device 1210 transmits the first identification code to the receiving end control unit 1224 in the receiving end device 1220. The first transmitting end control unit 1212 and the receiving end control unit 1224 both preset to store a list of identification codes corresponding to the color of the light. For example, the first transmitting end device 1210 is set to be assigned to the identification code #1 when it leaves the factory, and its corresponding number An identification image is red, and the second transmitting end device 1230 is set to be assigned to the identification code #2 when it leaves the factory, and its corresponding second identification image is green, and so on. In this way, when the first transmitting end device 1210 and the receiving end device 1220 establish a connection, the receiving end control unit 1224 will record that the first transmitting end device 1210 has the identification code #1. Similarly, when a connection is established between the second transmitting end device 1230 and the receiving end device 1220 later, the receiving end control unit 1224 will record that the second transmitting end device 1230 has the identification code #2. The receiving end control unit 1224 can know that the first identification image corresponding to the identification code #1 is red, and the second identification image corresponding to the identification code #2 by referring to the preset stored list of identification codes corresponding to the color of the light. It's green. In this embodiment, the first recognition image and the second recognition image are respectively made of red and green For example, it is not limited to this. The first recognition image and the second recognition image can also be Arabic numerals "1" and "2", or English letters "A" and "B", respectively.

於步驟1106中，接收端控制單元1224通知第二傳送端控制單元1232將第二視訊資料Vid2與第二識別圖像合成第二合成視訊資料Vid_C2。 In step 1106, the receiving end control unit 1224 notifies the second transmitting end control unit 1232 to synthesize the second composite video data Vid_C2 with the second video data Vid2 and the second identification image.

於步驟1108中，經由第一傳送端裝置1210傳送第一合成視訊資料Vid_C1給接收端控制單元1224。於步驟1110中，經由第二傳送端裝置1230傳送第二合成視訊資料Vid_C2給接收端控制單元1224。於步驟1112中，接收端控制單元1224將第一合成視訊資料Vid_C1與第二合成視訊資料Vid_C2合成為一個分割畫面視訊資料Vid_C3，接收端控制單元1224並將分割畫面視訊資料Vid_C3輸出至顯示裝置1260。 In step 1108, the first composite video data Vid_C1 is transmitted to the receiving end control unit 1224 via the first transmitting end device 1210. In step 1110, the second composite video data Vid_C2 is sent to the receiving end control unit 1224 via the second sending end device 1230. In step 1112, the receiving end control unit 1224 synthesizes the first synthesized video data Vid_C1 and the second synthesized video data Vid_C2 into a split screen video data Vid_C3, and the receiving end control unit 1224 outputs the split screen video data Vid_C3 to the display device 1260 .

如第11圖所示，本實施例之辨識視訊訊號來源的方法可選擇性地包含步驟1102、1114與1116。於步驟1102中，此接收端裝置1220內的接收端控制單元1224判斷是否同時接收到(a)第一傳送端裝置1210所傳送的第一視訊資料Vid1與(b)第二傳送端裝置1230所傳送的第二視訊資料Vid2，若是則執行步驟1104，若否則執行步驟1114。藉由步驟1102，接收端控制單元1224判斷是否超過1個傳送端裝置傳送視訊資料給接收端裝置1220。步驟1114~1116係針對如下情境：雖然第一傳送端裝置1210和第二傳送端裝置1230均已經與接收端裝置1220建立連線，(1)當只有第一傳送端裝置1210正在傳送第一視訊資料Vid1給接收端裝置1220，顯示裝置1260整個畫面都在顯示第一 視訊資料Vid1時，參與會議者能夠很清楚地理解到目前是操作第一傳送端裝置1210的簡報者正在輸出第一視訊資料Vid1，如此第一傳送端控制單元1212可以省略在顯示裝置1260中顯示識別碼對應的顏色，例如第一傳送端控制單元1212可以關閉第一傳送端控制單元1212內的視訊合成電路，來降低接第一傳送端控制單元1212的電能消耗。(2)當第一傳送端裝置1210傳送第一視訊資料Vid1給接收端裝置1220，且同時第二傳送端裝置1230傳送第二視訊資料Vid2給接收端裝置1220時，顯示裝置1260以分割畫面方式同時顯示第一視訊資料Vid1和第二視訊資料Vid2時，參與會議者此時無法清楚辨識視訊訊號時，此時第一傳送端控制單元1212才需要在顯示裝置1260中顯示識別碼對應的顏色，例如第一傳送端控制單元1212此時才啟動第一傳送端控制單元1212內的視訊合成電路。如此針對上述(1)和(2)兩種情境，第一傳送端控制單元1212可以動態關閉第一傳送端控制單元1212內的視訊合成電路，動態地降低第一傳送端控制單元1212的電能消耗，達成省電效果。 As shown in FIG. 11, the method for identifying the source of a video signal of this embodiment can optionally include steps 1102, 1114, and 1116. In step 1102, the receiving end control unit 1224 in the receiving end device 1220 determines whether (a) the first video data Vid1 sent by the first sending end device 1210 and (b) the first video data Vid1 sent by the second sending end device 1230 are received simultaneously. For the transmitted second video data Vid2, if yes, execute step 1104, if otherwise, execute step 1114. In step 1102, the receiving end control unit 1224 determines whether more than one transmitting end device transmits video data to the receiving end device 1220. Steps 1114~1116 are for the following scenario: Although both the first transmitting end device 1210 and the second transmitting end device 1230 have established a connection with the receiving end device 1220, (1) When only the first transmitting end device 1210 is transmitting the first video The data Vid1 is sent to the receiving end device 1220, and the entire screen of the display device 1260 is displaying the first When the video data Vid1, the participants can clearly understand that the presenter who is currently operating the first sending end device 1210 is outputting the first video data Vid1, so the first sending end control unit 1212 can omit displaying on the display device 1260 The color corresponding to the identification code, for example, the first transmitting end control unit 1212 can turn off the video synthesis circuit in the first transmitting end control unit 1212 to reduce the power consumption of the first transmitting end control unit 1212. (2) When the first transmitting end device 1210 transmits the first video data Vid1 to the receiving end device 1220, and at the same time the second transmitting end device 1230 transmits the second video data Vid2 to the receiving end device 1220, the display device 1260 adopts a split screen mode When the first video data Vid1 and the second video data Vid2 are displayed at the same time, when the participants cannot clearly identify the video signal at this time, the first transmitting end control unit 1212 needs to display the color corresponding to the identification code on the display device 1260. For example, the first transmitting end control unit 1212 only activates the video synthesis circuit in the first transmitting end control unit 1212 at this time. In this way, for the above two scenarios (1) and (2), the first transmitting end control unit 1212 can dynamically turn off the video synthesis circuit in the first transmitting end control unit 1212 to dynamically reduce the power consumption of the first transmitting end control unit 1212 , To achieve power saving effect.

如上段所述，步驟1114所對應的情境例如是接收端控制單元1224只接收到(a1)第一傳送端裝置1210所傳送的第一視訊資料Vid1和(b)第二傳送端裝置1230所傳送的第二視訊資料Vid2二者其中之一，且本發明步驟1114是以接收到第一傳送端裝置1210所傳送的第一視訊資料Vid1為例說明。於步驟1114中，經由第一傳送端裝置1210傳送第一視訊資料Vid1給接收端控制單元1224。於步驟1116中，接收端控制單元1224將第一視訊資料Vid1顯示在顯示裝置中1260。如第11 圖所示，步驟1114~1116是以接收端控制單元1224接收到第一視訊資料Vid1，但未接收到第二視訊資料Vid2為例來作說明，但不限於此。類似地，當於步驟1114中，接收端控制單元1224係接收到第二視訊資料Vid2，但未接收到第一視訊資料Vid1時，則對應的步驟1114~1116則對應地修改為：於步驟1114中，經由第二傳送端裝置1230傳送第二視訊資料Vid2給接收端控制單元1224；而於步驟1116中，接收端控制單元1224是將第二視訊資料Vid2顯示在顯示裝置中。 As mentioned in the previous paragraph, the scenario corresponding to step 1114 is, for example, that the receiving end control unit 1224 only receives (a1) the first video data Vid1 sent by the first sending end device 1210 and (b) the second sending end device 1230. The second video data Vid2 is one of the two, and step 1114 of the present invention is described by taking the first video data Vid1 sent by the first sending end device 1210 as an example. In step 1114, the first video data Vid1 is transmitted to the receiving end control unit 1224 via the first transmitting end device 1210. In step 1116, the receiving end control unit 1224 displays the first video data Vid1 on the display device 1260. As in section 11 As shown in the figure, steps 1114 to 1116 are described by taking the receiving end control unit 1224 receiving the first video data Vid1 but not receiving the second video data Vid2 as an example, but it is not limited to this. Similarly, when in step 1114, the receiving end control unit 1224 receives the second video data Vid2, but does not receive the first video data Vid1, the corresponding steps 1114 to 1116 are correspondingly modified to: in step 1114 In step 1116, the receiving end control unit 1224 displays the second video data Vid2 on the display device through the second transmitting end device 1230 to transmit the second video data Vid2 to the receiving end control unit 1224.

對應於步驟1104，第一傳送端裝置1210依照第一識別碼，第一傳送端控制單元1212將第一視訊資料Vid1與第一識別圖像(例如紅色識別圖像)合成第一合成視訊資料Vid_C1，並將第一合成視訊資料Vid_C1輸出至接收端裝置1220。當第一合成視訊資料Vid_C1顯示在顯示裝置1260中時，第一合成視訊資料Vid_C1對應於第一視訊區域與第一識別區域，第一視訊區域鄰近第一識別區域，第一視訊區域顯示第一視訊資料Vid1，第一識別區域顯示第一識別圖像；本實施例的第一視訊區域與第一識別區域同第4A~4C圖所示第一實施例的第一視訊區域462與第一識別區域464。第一傳送端裝置1210之第一指示裝置1216同時顯示第一識別圖像(例如紅色識別圖像)。於本實施例中，第一傳送端控制單元1212將第一視訊資料Vid1與紅色識別圖像合成第一合成視訊資料Vid_C1，使在顯示裝置1260中顯示對應的紅色識別圖像，且使第一傳送端裝置1210上的指示燈顯示識別碼#1所對應的紅色。以此類推，第二傳送端控制單元1232將第二視訊資料Vid2與綠色識別圖像合成第二合成視訊資料Vid_C2，並將第二 合成視訊資料Vid_C2輸出至接收端裝置1220，進而使在顯示裝置1260中顯示對應的綠色識別圖像，且使第二傳送端裝置1230上的第二指示裝置1236(例如指示燈)顯示識別碼#2所對應的綠色。 Corresponding to step 1104, the first sending end device 1210 according to the first identification code, the first sending end control unit 1212 synthesizes the first video data Vid1 and the first identification image (for example, the red identification image) into the first composite video data Vid_C1 , And output the first synthesized video data Vid_C1 to the receiving end device 1220. When the first composite video data Vid_C1 is displayed in the display device 1260, the first composite video data Vid_C1 corresponds to the first video area and the first recognition area, the first video area is adjacent to the first recognition area, and the first video area displays the first Video data Vid1, the first recognition area displays the first recognition image; the first video area and the first recognition area of this embodiment are the same as the first video area 462 and the first recognition of the first embodiment shown in Figures 4A to 4C Area 464. The first indicating device 1216 of the first transmitting end device 1210 simultaneously displays the first recognition image (for example, the red recognition image). In this embodiment, the first sending end control unit 1212 synthesizes the first video data Vid1 and the red recognition image into the first composite video data Vid_C1, so that the corresponding red recognition image is displayed on the display device 1260, and the first The indicator light on the transmitting end device 1210 displays red corresponding to the identification code #1. By analogy, the second sending end control unit 1232 combines the second video data Vid2 and the green identification image into the second composite video data Vid_C2, and combines the second video data Vid_C2 with the green identification image. The synthesized video data Vid_C2 is output to the receiving end device 1220, so that the corresponding green identification image is displayed on the display device 1260, and the second indicating device 1236 (such as the indicator light) on the second transmitting end device 1230 displays the identification code# 2 corresponds to the green color.

於本實施例中，其中第一傳送端裝置內的第一識別碼與第二傳送端裝置內的第二識別碼例如可為此傳送端裝置出廠時被設定分配到的顏色識別碼，然不限於此。第一識別碼亦可選自於由硬體序號，使用者輸入資訊以及網路位址所構成的群組其中之一。例如提供第一視訊資料Vid1的第一視訊源1250係為第一使用者所使用的一資訊處理裝置(例如筆記型電腦)，資訊處理裝置執行作業系統(例如微軟視窗Windows作業系統)，第一識別碼係為由作業系統提供的使用者資訊(例如微軟視窗Windows作業系統控制台內所設定第一使用者之個人資訊)，例如是「Peter」；則資訊處理裝置傳送「Peter」給第一傳送端裝置1210作為第一識別碼。又例如第一視訊資料Vid1源係為一資訊處理裝置(例如筆記型電腦)，其上具有攝影機拍攝第一使用者之人像；則資訊處理裝置傳送第一使用者之人像給第一傳送端裝置1210作為第一識別碼。又例如第一視訊資料Vid1源係為一資訊處理裝置(例如筆記型電腦)，其連上網際網路而具有一網路IP位址；則資訊處理裝置傳送網路IP位址給第一傳送端裝置1210作為第一識別碼。又例如第一傳送端裝置1210具有出廠硬體序號，第一識別碼係為第一傳送端裝置1210的出廠硬體序號。又例如資訊處理裝置執行一通訊軟體，(例如Line、Skype等)，資訊處理裝置取得登錄者使用者之個人資訊，例如是「Peter」；則資訊處理裝置傳送「Peter」給第 一傳送端裝置1210作為第一識別碼。以上所述任何可以辨識資訊處理裝置的資訊都可以應用作為第一識別碼。當第一識別碼是「Peter」、出廠硬體序號或網路IP位址時，則第一識別圖像就是上述文字的圖像。當第一識別碼是第一使用者之人像時，則第一識別圖像就是第一使用者之人像。 In this embodiment, the first identification code in the first transmitting end device and the second identification code in the second transmitting end device can be, for example, the color identification code assigned to the transmitting end device when it leaves the factory, but not Limited to this. The first identification code can also be selected from one of the group consisting of hardware serial number, user input information, and network address. For example, the first video source 1250 that provides the first video data Vid1 is an information processing device (such as a notebook computer) used by the first user, and the information processing device runs an operating system (such as a Microsoft Windows operating system). The identification code is the user information provided by the operating system (such as the personal information of the first user set in the Microsoft Windows operating system console), such as "Peter"; the information processing device sends "Peter" to the first The transmitting end device 1210 serves as the first identification code. For another example, the source of the first video data Vid1 is an information processing device (such as a notebook computer), which has a camera to take a portrait of the first user; the information processing device sends the portrait of the first user to the first sending end device 1210 is used as the first identification code. For another example, the source of the first video data Vid1 is an information processing device (such as a notebook computer), which is connected to the Internet and has a network IP address; the information processing device transmits the network IP address to the first transmission The end device 1210 serves as the first identification code. For another example, the first transmitter device 1210 has a factory hardware serial number, and the first identification code is the factory hardware serial number of the first transmitter device 1210. For another example, the information processing device executes a communication software (such as Line, Skype, etc.), the information processing device obtains the personal information of the registrant user, such as "Peter"; the information processing device sends "Peter" to the first A transmitting end device 1210 serves as the first identification code. Any information described above that can identify the information processing device can be used as the first identification code. When the first identification code is "Peter", the factory hardware serial number or the network IP address, the first identification image is the image of the above text. When the first identification code is the portrait of the first user, the first identification image is the portrait of the first user.
