The fusion is, for example, to draw the signal source content to a corresponding position according to the position and size for signal source display in the analysis result, and to draw the ui icon button and the like at the corresponding position. Such as where the content from the signal source is displayed in the figure, labeled "signal source 1".
Further exemplary embodiments of the above-described signal retrieval and control system are given below.
The ui interface and signal source control device 12 includes an event acquisition unit 121, a ui interface and signal source response calculation unit 122, a ui data distribution unit 123, and a control data distribution unit 124. According to some other embodiments of the present invention, the various elements of the ui interface and source control device 12 may also be combined with each other or subdivided in different ways to achieve the overall functionality of the ui interface and source control device 12 as well.
The event acquisition unit 121 receives the input of the input generating means and sends the signal to the ui interface and signal source response calculation unit 122.
The ui interface and signal source response calculation unit 122 analyzes the user input sent by the event collection unit 121 to determine a control command for controlling the virtual ui interface and a control command for controlling the signal source corresponding to the input. The ui interface and signal source response calculating unit controls the virtual ui interface to respond (for example, enlarge the display window of the signal source 1) according to the control command for controlling the ui interface, sends the corresponding ui data (for example, information including the enlarged display window) after the virtual ui interface responds to the ui data distributing unit 123, and sends the ui data after responding to the display analyzing unit 18 through a first unidirectional transmission path formed by the control network switch 13, the unidirectional transmission device 14 and the video network switch 15. Meanwhile, the ui interface and signal source response calculating unit 122 also transmits control data (or control command) for controlling the signal source 1 to the control data distributing unit 124, and the control data distributing unit 124 transmits the control data (or control command) to the signal source 1 through the second unidirectional transmission path, so as to control the signal source 1. The second unidirectional transmission path includes, for example, a control network switch 13 and a unidirectional control device 161. The unidirectional control device 161 receives control data from the ui interface and signal source control apparatus 12 (from the control data distribution unit 124 therein), and controls the signal source 1 according to the control data, the signal source 1 responds to the control of the unidirectional control device 161, performs corresponding operations such as keyboard, mouse, touch, and the like, and unidirectionally transmits the content of the signal source 1 (such as video content in the form of video stream data) corresponding to the operation result or response result to the video encoding device 163 through a third unidirectional transmission device such as a video cable or a unidirectional optical fiber, the video encoding device encodes the video stream data into a network stream signal and transmits the video content in the form of the network stream signal to the display analysis device 18 via the video network switch 15. The ui interface and signal source response calculating unit 122 can also call up the ui data corresponding to the virtual ui interface to be operated on the screen 10 in a similar manner when receiving the input signal.
According to some embodiments, the unidirectional transmission device 14 may comprise a unidirectional fiber, and the ui data passes through the control network switch, and then reaches the video network switch, and is transmitted to the display resolution device 18 by the video network switch.
According to some embodiments, the composition of the unidirectional control device 161 and its manner of action on the signal source may vary accordingly, depending on the signal source. For example, in the case where the signal source is a computer, control data in the form of a protocol may be sent to the signal source through the unidirectional control device 161 to perform unidirectional control on the signal source, and the content of the signal source is not transmitted back to the unidirectional control device. In the case that the signal source is a camera or the like, the unidirectional control apparatus may include a unidirectional transmission device and a control device, the control device is configured to control the camera according to the control data, and the unidirectional transmission device may block the content of the camera from flowing out in a reverse direction toward the unidirectional control apparatus. For example, the unidirectional control device may include a unidirectional transmission apparatus and a usb controller, where the usb controller is a standard usb-hid device and is connected to the signal source through the usb, and can control the signal source through a keyboard and a mouse.
The display analysis device 18 is configured to receive and analyze the ui data, receive a network stream signal from the video network switch, decode the network stream signal into video stream data, merge the video stream data with an analysis result of the ui data, and output a result of the merging on the screen. According to the illustrated embodiment, the display parsing means 18 may comprise a video decoding and display unit 181 and a ui data parsing unit 182. The ui data parsing unit 182 is configured to receive and parse the ui data sent by the ui data distribution unit 123, and send the parsing result to the video decoding and display unit 181. The video decoding and displaying unit 181 receives the analysis result, on the one hand, and also receives the video content in the form of the network stream signal from the signal source 1 of the video network switch, decodes it into video stream data, and merges the video stream data with the ui data analysis result sent by the ui data analyzing unit, and outputs the result of the merging onto the screen 10, and the content finally presented on the screen 10 includes an interface in response to the input of the input generating apparatus and the content of the signal source 1 displayed in the interface in response to the input.
Depending on the need or lack thereof for the network environment in the operating environment, in some other embodiments of the present invention, the constituent elements of the system described above may be varied, such as by having components therein associated with network access present or omitted. For example, 1) if a video network switch is not needed, only a control network switch is needed, and ui data can be transmitted to the display analysis device through the control network switch and the unidirectional transmission device; 2) if the network switch does not need to be controlled, only the video network switch is needed, and the ui data can be transmitted to the display analysis device through the one-way transmission device and the video network switch; 3) if the video network and the control network environment are not needed, the ui data can be directly transmitted to the display analysis device through the one-way transmission device. Corresponding to 1) above, the control data may be transmitted to the unidirectional control device via the control network switch. Corresponding to the above 2 and 3), the control data may be transmitted directly to the unidirectional control device. Corresponding to the above 1) and 3), the response result of the signal source is transmitted to the display analysis device through a unidirectional optical fiber or a unidirectional video line. Corresponding to the above 2), the response result of the signal source is encoded by the video encoding device, and the encoded result is transmitted to the video network switch through the unidirectional optical fiber or the unidirectional video line, and further transmitted to the display analysis device 18 by the video network switch. The unidirectional optical fiber or the unidirectional video cable can be replaced by other unidirectional transmission devices.
The functions of the above units can be realized by software or independent hardware.
Further, various details of the signal source acquisition and control process described previously with respect to fig. 1 may be applied herein, or may be applied thereto with appropriate adaptation. For the sake of simplicity, no further description is provided herein.
Through the embodiment of the invention, the user can have experience and efficiency similar to the operation of a local computer when calling and controlling the signal source, and simultaneously, the safety of the interaction process is ensured, and the high-security information is prevented from flowing into the low-security interaction equipment caused by the interaction process, for example, the content of the high-security signal source shown in the figure is prevented from flowing to the ui interface and the signal source control device or flowing to the low-security interaction end where the input generation device is positioned. Moreover, by introducing the virtual ui interface and separately transmitting the response result of the virtual ui interface and the content of the signal source to be called to the screen when the signal source is called and controlled, the information on one hand is lost or stolen on the transmission path, so that the whole information (including the interface and the signal source content) finally presented on the screen cannot be lost or stolen, namely the whole information presented on the screen still has safety.
For example, assume that the interface presented on the screen includes two boxes, one of which is red, representing an alert box, and the other of which is green, representing a security box, and that the content of all emergency signal sources is to be displayed in the red box of the interface, while the content of non-emergency signal sources is to be displayed in the green box. If the signal source content is intercepted separately during the signal source calling and controlling process, the interceptor still cannot determine the core information of the signal source, i.e. the signal source is an emergency signal source or a non-emergency signal source, because the light-dependent intercepting part cannot determine whether the signal source is finally placed in a red frame or a green frame.
