1. A driver assist information transmitter, which assists an occupant of a mobile station comprising;
- a driver assist information generator, which performs a readout of real time information and multimedia information to be added to said real time information as complementary information, and generates driver assist information to each element of said real time information, wherein said driver assist information is composed of said real time information, said multimedia information, and positional information, and wherein, said real time information is information to be updated at predetermined intervals, and said multimedia information includes at least one of image data, audio data, graphic data, and text data, and said positional information indicates the position of said element of said real time information;
a coded data compactor, which performs coding of said driver assist information using a specific description language in order to obtain coded driver assist information, and then performs the compaction of said coded driver assist information in order to obtain compacted coded driver assist information;
an event module constitutor, which generates a frame from an information part of said compacted coded driver assist information, and constitutes a module by classifying every frame based on said positional information, and then organizes an event, which is obtained by collecting all said modules, which are generated at the same time; and
a transmitter, which performs a modulation of said event in order to obtain a modulated event, and broadcasts said modulated event repeatedly at a fixed cycle.

Abstract
A driver assist information providing system includes a driver assist information transmitter and a driver assist information receiver. In the driver assist information transmitter, driver assist information having positional information and multimedia information are generated to each element of real time information by a driver assist information generator. After coding and compacting by a coded data compactor, an event constructed by an event module constitutor is broadcasted by a transmitter as a modulated event. In the driver assist information receiver, the driver assist information is obtained through the demodulation by an event module demodulator and decompression and decoding by a driver assist information obtainer. Then, the driver assist information to be required is selected by the driver assist information obtainer using positional information obtained by a current position obtainer, and is indicated on a display device.
