Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, the present disclosure provides an external computer module for use in an all-in-one interactive apparatus, which includes a central processing unit 11 and a pluggable connector 20. The external computer module further comprises: a video signal acquisition interface 12 for acquiring a video signal of an external device; and the video acquisition card 13 is connected with the video signal acquisition interface 12 and is used for converting the video signal into a standard signal which can be processed by the central processing unit 11 and sending the standard signal to the central processing unit 11.

The interactive all-in-one machine is a multimedia interactive terminal, takes a high-definition liquid crystal screen and the like as a display and operation platform, has the functions of writing, commenting, drawing, synchronous interaction, multimedia entertainment, network conference integration and the like, integrates multiple technologies of high-definition display, man-machine interaction, multimedia information processing, network transmission and the like, and is a preferred solution for office, teaching and graphic interactive demonstration in the information era. The external computer module is generally a general pc (personal computer) architecture, and the present disclosure adds a video signal acquisition interface 12 and a video acquisition card 13 to the existing P architecture, where the video signal acquisition interface 12 is used to connect to local external devices such as a notebook computer, etc., to acquire a video signal uploaded by the local external devices, and then converts the video signal into a standard signal that can be processed by the central processing unit 11, such as a signal of a usb (universal Serial bus) protocol, etc., through the video acquisition card 13. After the central processing unit 11 acquires the standard signal, the standard signal can be shared by using built-in video conference software and the like, so that the convenience of the participants in video sharing in the local external device is improved.

Referring to fig. 2, in one embodiment, the external computer module further includes a south bridge chip 14; the south bridge chip 14 is connected to the central processing unit 11 and the video capture card 13, respectively, and is configured to transmit the standard signal to the central processing unit 11.

The south bridge 14 is one of the chips in the chipset architecture of the pc motherboard for processing low speed signals. The purpose of the present disclosure of using the south bridge chip 14 to forward the above-mentioned standard signal to the central processing unit 11 is that the south bridge chip 14 has a USB interface and a PCIE (peripheral component interconnect express) interface, and may provide more choices for developers, such as selecting to convert a video signal into a signal of a PCIE protocol, or converting the video signal into a signal of a USB protocol, etc.

Further, since the standard signal is a signal of a USB protocol or a signal of a PCIE protocol, the video capture card 13 selects a capture card with a corresponding conversion function. The video capture card 13, which corresponds to the type of the video signal capture interface 12 and converts the video signal into a signal of the USB protocol or a signal of the PCIE protocol, may be any one of the prior art, and is not described herein again.
