Abstract:
1. A real-time video transmission system comprising: a wireless video input device; a wireless data transmission interface; and a computer comprising: a virtual camera module comprising a register for video and control data; a data management module for building a connection with the wireless video input device through the wireless data transmission interface and repeatedly accessing the register for video and control data to determine if there is an instruction, which is related to the wireless video input device, stored in the register for video and control data; and an application program module, wherein when a real-time video request is received, the application program module transmits the real-time video request to the virtual camera module, wherein when the virtual camera module receives the real-time video request, the virtual camera module writes the real-time video request into the register for video and control data and starts to access the register for video and control data repeatedly to determine if there is a real-time video stream stored in the register for video and control data, wherein in response to determination that there is the real-time video request, which is taken as an instruction related to the wireless video input device, stored in the register for video and control data, the data management module obtains the real-time video request from the register for video and control data, when the data management module obtains the real-time video request from the register for video and control data during accessing of the same, the data management module drives the wireless video input device to film and send back a real-time video stream, the data management module writes the received real-time video stream into the register for video and control data, wherein in response to determination that there is the received real-time video stream stored in the register for video and control data, the virtual camera module obtains the received real-time video stream from the register for video and control data, when the virtual camera module obtains the received real-time video stream from the register for video and control data during accessing of the same, the virtual camera module transmits the real-time video stream to the application program module.
