2 is a schematic diagram of an embodiment of a display device 100. As shown in FIG. 2, the display device 100 includes a screen 103, a processing device 110, and a display computing device 120. The display device 100 can simultaneously receive the local video V1 and the monitoring video V2 through an external interface (such as HDMI, VGA or RJ45), and then the user selects one of the videos as a display screen and displays it on the screen. The processing device 110 receives the monitoring video V2 and determines a notification message according to the analysis of the image, and the content includes the priority level and the abnormality type. The processing device 110 further determines an alert signal A according to the notification message and a warning rule. The display computing device 120 can As a scaler, it can receive the local video V1, the surveillance video V2 and the warning signal A, and determine the image to be displayed on the screen 103 according to the warning signal A.

In other examples, the display device 100 can be a tablet or a multi-function computer (All In One PC), and the local video V1 can be generated by the display device 100. In other words, a display device integrating the image providing unit can be employed. The processing device 110 processes the monitoring video V2 and transmits it to the display computing device 120. For example, processing device 110 decodes surveillance video V2 and combines multiple surveillance video V2 from different network cameras 300. It is determined whether a notification message is generated according to the monitoring video V2 and the preset comparison condition.

In one embodiment, the notification message is generated by processing device 110 in accordance with the comparison condition. The aforementioned comparison conditions are, for example, abnormal conditions such as intrusion of a person or an animal, and shielding of a camera lens. A notification message is generated when the processing device 110 detects an abnormal situation such as a person entering, obscuring a lens, or an animal intrusion after image processing and comparison of the signal. The processing device 110 generates the warning signal A according to the notification message and the warning rule. The alert rule may include, for example, a correspondence between the usage context and the notification message. In other words, the processing device 110 can confirm which abnormal condition is caused by the notification message, and generate the warning signal A according to the warning rule.

Referring to the embodiment of Table 1, the warning rules define two usage scenarios of the screen display monitor screen and the screen display local screen, and the notification message may have a priority level and an abnormal condition such as: personnel intrusion, shadowing The lens and the animal broke into three abnormal conditions. The first two abnormal conditions have a high priority and the animal intrusion is a low priority. When an abnormal condition occurs, the warning signal A generated according to the notification message and according to the warning rule includes an instruction to perform a screenshot. The aforementioned priority level is an adjustment of the difference in the warning effect in the instruction, for example, the same level of abnormal conditions produce the same screenshot effect (such as hue, transparency, etc.), while the lower priority level can be used to take a higher transparency after the screenshot. Displayed on the monitor screen or the local screen to avoid disturbing the user's viewing of the screen being watched. In another embodiment, in the case of low priority, the text of "animal break" can be used instead of the screen. Display without displaying the screenshot screen.

On the other hand, the usage context may, for example, include the amount of computational load of the display computing device. In other words, the aforementioned two usage scenarios can be distinguished according to the operational load of the display computing device. For example, when the local video is displayed, the display computing device 120 performs a relatively large amount of video processing or calculation. Therefore, the amount of computation load when the monitor screen is displayed is smaller than the amount of computation load of the local screen. Therefore, the user is judged to be watching. In the case of local video, in the abnormal situation of the animal in Table 1, the high-transparency screenshot is displayed to avoid too much influence on the user's concentration, and thus the user can be displayed while watching the monitor screen. Transparent screenshot window; in a certain In some cases, even if the local video is displayed, the computing load may have different levels. For example, the fast moving picture and the still picture will have different effects on the computing load. In this state, the warning rule can be based on Different calculation load sets different rules, such as adjusting the transparency of the screenshot corresponding to the calculation load.

It should be added that the above screenshot refers to the screenshot screen generated according to the monitoring video. Returning to Fig. 2, specifically, the display arithmetic unit generates a local screen and a monitor screen based on the local video and the surveillance video. The warning signal A may include a screenshot request, and the display computing device generates a screenshot screen from the monitoring video according to the screenshot request, and forms a composite screen of the screenshot screen on the screen when the local screen or the monitoring screen is displayed, to remind the user that an abnormality occurs. situation.

The display computing device 120 receives the local video V1 and the surveillance video V2. The processing device 110 processes the monitoring video V2 and transmits it to the display computing device 120. According to the monitoring video V2 and determining whether to generate a notification message according to the preset comparison condition.

In one embodiment, the notification message S is image processed by the network camera 300 and is generated according to the comparison condition. For example, after the image recognition by the network camera 300, an abnormal condition is found, and the notification message S and the monitoring video V2 are simultaneously transmitted to the display. Device 100. As shown in FIG. 3, the processing device 110 includes an event processor 112 configured to parse the notification message and generate the alert signal A according to the notification message and the alert rule.

Please refer to Table 2, the warning rules may include displaying the monitoring screen and displaying the two screens of the local screen, and the notification message may have a priority level and an abnormal condition, such as: an intrusion, a lens, and an animal intrusion. The form of the. These three abnormal conditions have different priority levels. When an abnormal condition occurs, a screenshot of different effects is generated according to the warning rule. For example, a high level of abnormality produces a low transparency or a transparency-free screenshot effect that makes the user aware of an abnormal condition, an abnormality in the level produces a screenshot of the transparency, and a low level of abnormality produces a high transparency. Screenshots to avoid obscuring the user's current viewing.

Taking Figure 3 and Table 2 as an example, the warning signal A contains a screenshot request. The screenshot request corresponds to different priority levels including transparency adjustments, so that the transparency of the screenshot screen is different from the transparency of the native screen and the monitor screen. For example, in Table 2, the high level of abnormal conditions can produce the lowest-resolution screenshot screen accordingly, so that the user can clearly remind the user of an abnormal event. The display computing device 120 generates a screenshot screen from the monitoring video V2 according to the screenshot request, and forms a composite screen having a screenshot screen combined with a native screen or a monitoring screen.

The processing device 110 processes the monitoring video V2 and transmits it to the display computing device 120. The display computing device 120 receives the local video V1 and the surveillance video V2, and the user selects one of the videos to be displayed by the screen 103. According to the monitoring video V2 and determining whether to generate a notification message according to the preset comparison condition. In addition, the processing device 110 includes an event processor 112 configured to parse the notification message and generate the alert signal A according to the notification message and the alert rule.

In one embodiment, the screen camera 130 can be oriented, for example, in the same direction as the display surface, thereby knowing whether the user is in front of the display device. For example, it is determined by the size of the captured image that the user is within a range of 1 meter in front of the display device. The Bluetooth receiving device 140 can be, for example, a positioning signal receiving device using Bluetooth low energy technology, and can detect a Bluetooth signal such as a user's mobile phone or a wearable device. Thereby, it is judged whether the user is in front of the display device. In general, the sensing device is configured to sense whether a user is in front of the display device to generate a sensing result, and determine a usage context and a warning rule based on the sensing result.

In addition, as shown in FIG. 7, the network monitoring system includes an input device 400 in addition to the display device 100. An input device 400 such as a keyboard or a mouse is connected to the display device 100. The input device 400 has a switching service. When the switching service is triggered, the display computing device 120 switches to display on the local screen, the monitor screen, or the composite screen. The switching service may be, for example, a Display Data Channel/Command Interface (DDC/CI), which is a communication protocol that can change the display information of the display device through a keyboard or a mouse. For example, the keyboard can be switched according to the service setting shortcut button. When the user leaves the display device and is notified of an abnormal situation, the user can trigger the switching service through the button operation before returning to the display device, so that the display computing device is self-registered. The screen changes to a composite screen.

This allows you to quickly switch to the viewing style your users need.

Please refer to Table 3, as shown in Table 3, the warning rules define three kinds of usage scenarios: display monitoring screen, display local screen and user leaving the display device, and define three abnormal conditions: personnel intrusion, shielding lens and animal intrusion. These three abnormal conditions have different priority levels. In general, the alert rule includes a combination of a plurality of correspondences, such as a correspondence between the notification message and the computing load of the display computing device, and a correspondence between the notification message and whether the user leaves the display device. When an abnormal condition occurs, for example, a screenshot or a warning sound of a different effect may be generated according to the warning rule.

Further, the alert rule may set at least one alert action for each usage context and an abnormal condition, for example, setting a combination with different alert actions. As shown in Table 3, in the warning rule, for the usage situation of viewing the monitoring screen, four kinds of warning actions (screenshot, text, warning tone, and warning light) or a warning action (screenshot) are set at different priority levels. For viewing the usage scenarios of the local screen, three alert actions (screenshots, text, and warning lights) or a warning action (text) are set at different priority levels. For the usage situation of leaving the display device, two kinds of warning actions (warning tone and warning light) are set correspondingly in the level high and the level, and an alert action (warning tone) is set correspondingly in the low level.

For example, the different warning sounds in Table 3 can be set, for example, that the warning sound A1 is a continuous short sound and is a high volume, the warning sound A2 is a three long sound and is a medium volume, and the warning sound A3 is a voice broadcast. The foregoing priority level refers to the difference in the warning effect. For example, when the user views the monitoring screen, the high level abnormal condition produces a low transparency screenshot, text, warning sound A1, warning light B1, and the like. When leaving the display device, the abnormal state of the middle is correspondingly generating the warning sound A2 and the warning light B2.

In addition, the different warning lights in Table 3 can be set, for example, that the warning light B1 is a flashing red light, and the warning light B2 is a flashing green light. In addition to being separated by the color of the light, the warning light can also be set to a different blinking frequency.

Taking Figure 7 and Table 3 as an example, the warning signal A contains a voice prompt request. As shown in FIG. 7, the display device 100 includes a sound controller 150 coupled to the sound amplifying device 160. Alert signal A contains a voice prompt request. The voice prompt request corresponds to a different priority level including a warning tone adjustment. The sound controller 150 receives the voice prompt request to generate a different alert tone for the sound amplification device 160. In addition, the alert signal A may include a screenshot request. Corresponding to different abnormal conditions, the warning signal A generated by the processing device 110 according to the warning rule may be a combination of a warning sound or a warning sound and other warning actions.

As shown in FIG. 7, the display device 100 includes a light source controller 170 connected to the peripheral light source 180. The warning signal A contains a lighting prompt request. The illumination prompt request corresponds to different priority levels including warning light adjustment. The light source controller 170 receives the lighting prompt request to generate different warning lights for the peripheral light source 180. In addition, the alert signal A may include a voice prompt request or a screenshot request. Corresponding to different abnormal conditions, the warning signal A generated by the processing device 110 according to the warning rule may be generated by the warning sound combined with the warning light, or the warning sound may be generated separately.

For text warnings, for example, the alert signal also includes a text prompt request. Referring to Figures 7 and 3, processing device 110 includes a picture controller 114. Warning signal A contains a text prompt request. The text prompt request can generate a corresponding event description corresponding to different priority levels. The picture controller 114 generates a warning text based on the text prompt request to describe the detected abnormal condition. The display arithmetic unit 120 receives the warning text transmitted from the screen controller 114, and forms a text prompt screen having the warning text superimposed on the local screen or the monitor screen. For example, when viewing the monitor screen, a high level of abnormality (personnel intrusion) can generate a warning text of "personnel intrusion" and superimpose it on the monitor screen where the person is photographed.

As mentioned above, the alert rule sets a combination with different alert actions. In other words, the alert signal A may include a text prompt request, a voice prompt request, a light prompt request, and/or a screenshot request. Corresponding to different abnormal conditions, the warning signal A generated by the processing device 110 according to the warning rule may be generated by a screenshot, a text, a warning tone, and an alert light, or only one of the alert actions may be generated. In general, the processing device 110 can generate the alert signal A configured corresponding to the corresponding relationship (ie, the correspondence between the notification message and the usage context) according to the alert rule. In other words, the alert signal A has a different configuration, the configuration including at least one alert action, as shown in Table 3 above. For example, the processing device 110 detects that the display computing device 120 has a low computation amount and detects a notification message of a corresponding high level. The alarm signal A generated at this time has a first configuration, and includes four types of alert actions. Work. For another example, the processing device 110 detects that the user leaves the display device 100 and detects the notification message in the corresponding level. The alarm signal A generated at this time has a sixth configuration and includes two alert actions.

FIG. 8 is a schematic diagram of another embodiment of the warning mode. As shown in FIG. 8, the user leaves the display device 100. When an abnormal condition occurs, the processing device knows that the user leaves the display device 100 according to the image captured by the screen camera 130, and generates the warning signal A according to the warning rule. The display computing device generates a warning sound through the sound reinforcement device 160 in response to the voice prompt request. This allows the user to immediately detect abnormal conditions.

Figure 9 is a schematic diagram of another embodiment of the alert mode. As shown in FIG. 9, the user is testing the game, and the display computing device displays the local screen P1 on the display device 100 in accordance with the local video. The processing device generates a warning signal A when a person breaks in. The display computing device generates a screenshot screen Q1 from the monitoring video according to the screenshot request. At the same time, according to the text prompt request, the warning text W1 and the number of the network camera are displayed on the screenshot screen Q1. In addition, the warning sound is sent from the sound amplification device 160 according to the voice prompt request and the light prompt request, and the warning light is emitted from the peripheral light source 180.

In the embodiment of Fig. 9, a composite screen is formed by the screenshot screen Q1 and the local screen P1. The screenshot screen Q1 is formed on the local screen P1 in a divided display manner. Further, the peripheral light source 180 is disposed in the same direction as the display surface, but is not limited thereto. In other embodiments, the peripheral light source 180 is disposed in a different direction than the display surface, such as on the back side of the display surface. Thereby, when the user leaves the display device 100, the user can immediately detect the abnormal condition. In general, with the network monitoring system of the present invention, different warning modes can be generated according to the type of abnormal conditions and the user's activity on the display device, and the effect of immediate warning can be achieved.
