Digital multimedia vehicle mounted navigation apparatus and navigation method

Abstract

The present invention provides a digital multimedia vehicular navigation device and a method thereof. The device comprises a GPS positioning unit, a central processor, a memory unit and a display unit. The vehicular navigation device further comprises a media playing unit for playing media, a data broadcasting information receiving unit for receiving media data sent through the data broadcasting and for transmitting the media data to the display unit to display or transmitting the media data to the media playing unit to play, a digital television receiving unit for receiving a ground digital television signal to carry out corresponding channel demodulation and information source decoding so as to play digital television programs, and a digital sound broadcasting receiving unit for receiving a digital sound broadcasting signal to play digital sound programs. The media data comprises at least one of electronic maps, traffic public information and personalized information. The device and the method can realize the functions of automatically updating the electronic maps and playing and displaying the road condition information in real-time, etc.

Description

technical field [0001] The invention relates to a global positioning system (GPS) navigation technology, in particular to a digital multimedia vehicle-mounted navigation device and a navigation method. Background technique [0002] At present, most of the existing vehicle navigation systems basically only have a separate GPS navigation function, which is used for vehicle satellite positioning, geographic information navigation, vehicle orientation and speed display and other functions. This type of vehicle navigation system has a relatively single function, and it is increasingly difficult to meet people's further performance requirements for this type of electronic product. Although some navigation devices have added the function of receiving analog TV and digital TV on this basis at present, the TV receiving function and the GPS navigation function are two independent functional modules, and the two parts just share a display. There is no data exchange and information sha...

AI Technical Summary

Problems solved by technology

This simple module superposition method cannot organically integrate the TV receiving function and GPS navigation function together, which restricts the expansion ability of the entire system function

In addition, because the current urban traffic is relatively congested, accidents such as traffic jams and traffic accidents have brought great inconvenience to driving, so people need to know real-time traffic information, traffic control information, etc. in a timely manner to avoid congested roads.

[0003] In addition, when the geographical information changes, the electronic map of the navigation device is difficult to be updated in time, which also brings great inconvenience to driving.

[0004] Moreover, in addition to displaying navigation information and receiving TV programs, the existing car navigation devices cannot display or play information related to the GPS position of the vehicle to the user (such as scenic spot introductions, shopping mall information, etc.), which restricts the expansion of navigation functions. and user experience
