Both to perceive the sound as a discursive or on a piece of paper draw a picture, once humans learned to practical tools that will automatically use them. For electronic communications, communication between electronic devices can only be done in compliance with a set of predefined rules and standards. Open system interconnection model for communication system protocol stack is the most basic example. Image transmission is a computer network and communication technology, such as an integrated system. Should be a large amount of information, class capacity is more intuitive. The use of the process is more convenient and widely used in various fields. However, in a small number of home or home address, such as the occurrence of environmental occasions, how to quickly mature to extract useful images. Is the focus that people always pay attention to.  control the red, yellow, green crossroads the traffic many of light on the state transition, to command all vehicles and pedestrians to pass safely, finally reach the intelligent management of traffic lights.
