Abstract

A projector capable of instantly sharing the images of the displayed slides, in addition to having the components and functions of a general projector, a signal processing device (101) and a network device (102) are also provided, and the signal processing device (101) converts input The video signal is converted into a video data stream, and the video data stream is provided to each network terminal (4) for extraction in a real-time manner through a network device (102). In some large-scale conferences, due to the large conference venue and the large number of people, not every position can clearly see the projector screen (2). With the projector (1) of the present invention, the conference participants can connect to the Internet as long as they carry them. The network terminal (4), such as a notebook computer, can extract the video data stream from the projector (1) through its notebook computer, instantly see the same image content as the screen (2), or download the lecturer's slideshow file , and the video data stream can be stored in the computer for easy viewing in the future.
