The present invention discloses a network real-time video collecting device based on FPGA chip and DSP chip development. The device of the invention comprises a video collecting module, a video signal processing module, a network control module, a handshake control module of press button switch and network protocol and an upper machine terminal alternation module. The device realizes the high-speed real-time collection and network transmission to analog video signal/analog television signal or high resolution computer signal. Based on the network handshake protocol between the upper machine and video collecting device which are developed independently on the video collection hardware platform, the specific data in the negotiation package can be flexibly set for controlling the working state of collecting device and realizing the network intelligent control of a plurality of video collecting devices. The device is composed of small-capability FPGA chip and intermediate-performance DSP chip, and can be widely used for the fields of enterprise/family guarding system, real-time video monitoring of operating interface of computer device, visual auxiliary drive of intelligent vehicle, etc.
