Abstract
A real-time video transmission system includes a wireless video input device, a wireless data transmission interface and a computer. The computer includes a virtual camera module, a data management module and an application module. The data management module repeatedly accesses a register. The virtual camera module writes a received real-time video request into the register. When the data management module obtains the real-time video request from the register during accessing of the same, the wireless video input device is driven to film and send back a real-time video stream. The data management module writes the received real-time video stream into the register. When the received real-time video stream is obtained from the register during accessing of the same, the virtual camera module transmits the real-time video stream to the application program module.
