Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

Referring to FIG. 1, an embodiment of the screen capture system 100 of the present invention includes a remote electronic device 1 and a display device 2. The remote electronic device 1 and the display device 2 communicate through a communication network 200. The remote electronic device 1 is, for example, a server, a computer device or a smart phone.

The display device 2 is, for example, a multimedia digital signage, a desktop computer screen or a TV. The display device 2 includes a panel unit 21, a processing unit 22, a signal distribution unit 23, a capture unit 24, a decoding unit 25, a storage unit 26, a communication unit 27, and a control unit 28.

The panel unit 21 is, for example, a liquid crystal panel unit. The processing unit 22 outputs a video signal that meets a predetermined transmission standard and is to be displayed by the panel unit 21. The predetermined transmission standard is, for example, LVDS (Low-voltage differential signaling), V-by-One, or eDP.

The signal distribution unit 23 includes an input port electrically connected to the processing unit 22 to receive the video signal, a first output port electrically connected to the panel unit 21 and outputting the video signal, and a first output port electrically connected to the capture unit. The unit 24 also outputs the second output port of the video signal.

The capture unit 24 receives the video signal, and can identify each frame contained in the video signal (for example, by identifying the horizontal and vertical synchronization signals of the video signal), and captures the current received signal during the period of receiving a trigger signal At least one frame of the received video signal generates a captured data. In other words, once the capturing unit 24 receives the trigger signal, it starts capturing from the latest complete frame of the video signal until the trigger signal is no longer received. In other words, as the length of time for receiving the trigger signal will affect the number of frames that the capture unit 24 will capture from the video signal, the longer the time for receiving the trigger signal, the capture unit 24 The larger the number of frames extracted from the video signal.

The decoding unit 25 is electrically connected to the capturing unit 24 to receive the captured data, and can decode the captured data to generate a video file. When the captured data is generated from a single screen, the video file is a picture file, and when the captured data is generated from multiple screens, the video file is a video file. The storage unit 26 is electrically connected to the decoding unit 25 to receive and store the video file.

The communication unit 27 is, for example, a WiFi communication unit, but not limited to this. The control unit 28 is electrically connected to the capture unit 24, the storage unit 26, and the communication unit 27, and can generate the trigger signal to the capture unit 24, and can access the video file stored in the storage unit 26, And the video file can be sent to the remote electronic device 1 via the communication unit 27.

The control unit 28 generates the trigger signal to the capture unit 24, for example, in the following three situations. The first situation is that when the control unit 28 receives a capture command from the remote electronic device 1 via the communication unit 27, the control unit 28 generates the trigger signal according to the capture command, and according to the capture command The corresponding video file is transmitted to the remote electronic device 1 via the communication unit 27. In this way, the effect of real-time capture and real-time provision of the video file to the remote electronic device 1 can be achieved.

The second situation is that the control unit 28 generates the trigger signal every predetermined period of time (for example, every 10 minutes). The third situation is that the control unit 28 generates the trigger signal at a predetermined time point (for example, at 10:00 am on a certain day of a certain month).

In summary, the screen capture system 100 of the present invention outputs the video signal to the capture unit 24 through the signal distribution unit 23, and captures the video signal according to the trigger signal generated by the control unit 28 through the capture unit 24 The video signal generates the captured data, and the decoding unit 25 decodes the captured data to generate the video file, so that the user can access the video file. In addition, the control unit 28 transfers the captured data through the communication unit 27. The video file is sent to the remote electronic device 1 so that the user can obtain the video file remotely, so the purpose of the invention can be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope of the patent for the present invention.
