Design of Wireless Video Image Transmission Systems Based on DSP

摘要

A kind of wireless video image transmission system is proposed, in order to offset the disadvantages of wired video monitor laying points, and disadvantages of wired video monitor implementation. The core of the system is the TI series of C5000 high speed DSP processor and the radio frequency wireless communication chip. Through DSP transplantation of JPEG compression algorithm, complete image collection and image compression through DSP, and use of wireless receiving and sending modules to complete wireless images data transmission. Use of a wireless receiving and sending module instead of emitter and network as the image data transmission device, is low cost, does not required network fee, and the system can complete terminal image collection and display in real-time. It can apply to the field of community security and video monitoring of critical points in the electric power system, in factories, in water conservancy systems, in laborators, in banks, and in other important facilities, which don't require higher performance.
