Mine long-range video supervision system based on DSP

The now available longrange supervision system at home and abroad is based on the optical fiber mostly, and if the optical fiber runs into that the machinery lashes and colliding optical fiber may split or break. Once splitted, it's hard to be restored because of the sophisticated equipment, and ordinary user can't restore it by means of the welding at all. In order to solve this problem, people have found a solution of using the longrange supervision system transmitting on the twistedpair at an extereme lowbit rate with less cost. The article aims to introduce a twistedpair video supervision system at an extreme lowbit rate based on lowcost TI DSP F206. It is an economical and practical longrange supervision system that possesses broadcasting ability. The author not only offers a complete scheme but also elaborates on some key points.5figs.,5refs.
