Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a switching method, and in particular, to a system and a method for switching settings in backup [prior art] In this age where every minute counts, The video conference can be said to be the overall service digital network (ISDN). Over the past year, many domestic companies have been connected internationally. These companies include industries, finance, automotive manufacturing, the United States, Australia, Japan and other places. The use of the video conference system can increase the room and improve the productivity of employees. Regardless of the emergency meeting, it is not necessary to consider the two parties to be held online. Not only shorten the decision-making video conference system, but generally the point-to-point communication is that the entire video is connected to each other through the network channel. discuss. Multipoint video conference method For conference discussion, the principle is through the point control unit (MCU), and each site needs to be connected to the system of the video capture device and its multiple video capture methods in the video conference. The latest tool for frequent communication and companies gradually moving to the country to respond to this trend. It has gradually spread to major cities in China, and adopts videoconferencing system for domestic electronics manufacturing, petrochemical industry, high-tech, etc. The connection location is far away from Europe, which reduces personnel travel costs, saves time, or The distance between the people in an emergency and the meeting can make the schedule more quickly and solve the problem. Divided into (1) point-to-point (2) the most basic type of multipoint conference, the communication pair allows the connected parties to have a video conference, but allows multiple participants to have the same ^ multipoint controller (M u 11 i- Management of conference agenda and communication. Multi-point controller control center, so set up time control or technical time tight cubicle time control. 1220370 V. Description of invention (2) -------- The control center is responsible for controlling each conference The screen and voice of the system are cut to multiple points for the purpose of conducting a conference at the same time. Because the pen has a portable computer, it can be used anywhere on the Internet and use a notebook computer and connect to it: Video capture devices (such as cameras, microphones, etc.) for video conferencing. For a notebook computer with a built-in camera, due to the stability on the camera device, the lens is generally centered. Solid & the edge of the display is 'but' this setting method not only makes the camera lens non-rotating, but also its angle of view is limited. Therefore, participants in video conferences: must be located on the LCD monitor for photography Only in front of the camera can your own image fall within the scope of the camera's camera. If more than one person participates in the video conference at the same time on the same notebook computer, you need to use multiple external cameras ^ to capture different Personnel image data. &Amp; Currently, the mainstream notebook computers are equipped with two USB ports, so a notebook computer with a built-in camera can be set with up to three available video capture devices. "Figure 1" is a schematic diagram of the operation day and time displayed on the screen of user B's laptop computer. When the video conference is in progress, participant B will receive the user himself (b) and others on his computer screen. Video data of participants A, C, and D. Generally, the video conference application must set up a set of videos to be used by users (b) before all participants A, b, C, and D are connected. Capture device 11 (choose one of the three video capture devices 11, 1, 2, 1 3 as a video conference, capture video data of the video data

Description of the invention (3) Source) 0 Also, during the video conference, the video data source (video capture device 1 1) for capturing video data cannot be changed, so the user cannot be received (B) Other people's image data. [Summary of the Invention] If the user wants to use other non-default video capture device 12 or video capture device 1 3 to capture video data, he must disconnect the line before setting another video capture. Device 1 2 or video capture device 1 3 captures video data and reconnects for video conference. This will not only interrupt the original video conference, but also prolong the entire video conference, which will cause inconvenience for all participants in the video conference. In view of the problems of the above-mentioned conventional technology, the system and method for switching settings in multiple sets of video capture devices disclosed in the present invention is a software-controlled method to facilitate users to switch differently during the video conference. Video capture devices 11, 1, 2, 1 3 to capture different video data. The user only needs to perform the function option of "switch lens" in the video conference operation day and time. When this "switch lens" function option is executed, a trigger signal will be generated to switch between different video capture devices 丨丨, 1 2 , 1, 3 to transmit video capture data from different locations of video capture devices 11, i 2, 1 3, and display the switched video image on the computers of all participants in the video conference, to achieve multi-person conference effect. Therefore, the present invention does not need to interrupt the network connection, reset other video capture devices 11, 1 2, 1 3, and reconnect again before it can be 1220370.
