However, in another embodiment of the present invention, the line concentrator module and the format conversion module are distributed on one circuit board, and the image processing module is arranged on another circuit board, and the circuit boards are connected by using a physical line. However, the present invention is not limited thereto, and the components may be freely disposed on different circuit boards as required. And each element comprising the line concentration module, the format conversion module and the image processing module is electrically connected with each other according to actual requirements.
The nature of each module and component will be described with reference to an embodiment.
The hub module mainly includes an image input port 1, a signal switch 2, a hub chip 3, a plurality of USB output ports 4, and so on. Specifically, the example of the hub module is a general name of Genesys GL3590S and its peripheral hardware architecture, and the present specification introduces all details of the GL3590S hub (such as all data loaded in the specification/description thereof) by reference, which are not repeated herein. As shown in the figure, the hub module can collect a plurality of image input ports 1 and a plurality of data output ports (i.e. USB output ports 4).

The wireless communication module 9 is, for example, a WIFI communication module; the wired communication module 10 is, for example, a network card corresponding to RJ 45.
The following description focuses on the present invention.
When the device is used, the network camera connected to the image input port 1 shoots and outputs multimedia data in a USB format, the multimedia data in the USB format reaches the line concentrator chip 3 through the signal switch 2, the line concentrator chip 3 transmits the multimedia data in the USB format to the image format conversion chip 5, the image format conversion chip 5 converts the format of the multimedia data in the USB format (initial format/first format) into an HDMI format (converted format/second format), and then the multimedia data converted into the HDMI format is output to a screen connected with the multimedia output port 6 according to requirements, or the multimedia data in the HDMI format is transmitted to the multimedia processing chip 7 for image processing. The multimedia processing chip 7 can then output the corresponding processed multimedia data with HDMI format to the first video output port 8 and output to the screen connected thereto. Alternatively, the processed multimedia data can be converted into TCP/IP format by the multimedia processing chip 7 and then outputted to another terminal on the network via the wireless communication module 9 or the wired communication module 10. Or, the processed multimedia data converted into USB format by the multimedia processing chip 7 can be transmitted to the second image output port 8 through the signal switch 2, the line concentration chip 3, and the image format conversion chip 5; alternatively, the data is outputted from the hub chip 3 to the data output port 4 for being transmitted to the outside via the USB transmission line to be played by another screen, or is stored in an electronic device such as a hard disk.
By means of the flow design of the present invention, the multimedia data from the system port (Host port) of the image input port 1 can be transmitted to the multimedia processing chip 7 for data analysis and post-processing, and then outputted. The problem that the image of the image input port 1 of the prior port expansion device can not be processed by post processing is solved.
The foregoing is directed to embodiments of the present application and it is noted that those skilled in the art may make various changes and modifications without departing from the spirit and scope of the application.
