摘要： Disclosed is a system and a method for collecting various road traffic information, road image information, and position information of a position information generation device carried by an object, the position of which is to be tracked, by interworking with an information provision means and using the collected information to provide service subscribers with real-time traffic information, traffic prediction, or position information of the object via wireless Internet, satellite broadcasting, DMB, or cable data broadcasting. The system and method can provide detailed traffic information service regarding a specific region or location on a nationwide scale, predict traffic to properly deal with it, and easily provide position information of an object to be tracked.

摘要： A wireless and multi-channel re-transmitting link is provided between an image displaying part that is housed in a first housing and an image data processing part that is housed in a segregated second housing. The wireless link allows the image displaying part to be more easily moved around and to be made lighter and slimmer in profile because at least some image data processing can be carried out in the second housing and yet cumbersome cables are not needed for linking the pre-processed image data from the second housing to the first housing. In one embodiment, the data bandwidth. that is to he transmitted through the wireless link is first reduced; for example the frame refresh rate of image frames conveyed through each of the wireless channels is made less than the frame refresh rate of the original image signal. In one embodiment, the reduced number of frames per unit time are further frequency wise and temporally wise spaced apart from one another by alternatingly sending them through different wireless channels at different times. Thus if a burst of noise strikes one of the plural re-transmission channels, the likelihood that it will corrupt a frame is reduced.
