BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital multimedia broadcasting receiver having a media storage / playback and navigation function. More particularly, the present invention relates to an audio / video storage and playback function and a vehicle navigation system using GPS in one portable multimedia player terminal. A terminal device having a device function and a digital multimedia broadcasting reception function.

With the widespread use of the Internet and full-scale digital broadcasting, the necessity of a terminal for accommodating various contents and multi-functional multi-channels is increasing day by day. In addition, due to various user demands, digital electronic devices have been miniaturized and complexed, and portable multimedia players (PMPs) and portable digital broadcasting devices, which are portable and have integrated functions, are being actively developed. In particular, with the introduction of a five-day workweek system, vehicle usage is increasing due to the increase in outdoor activities. As a single terminal, recent digital multimedia broadcasting (hereinafter referred to as DMB), storage / playback of digital audio, and vehicle navigation using GPS There is a growing demand for an integrated environment that can accommodate various functions such as devices. This raises the need for digital convergence products that reduce the hassle of users having to select multiple devices as needed.

The conventional terminal device having a digital multimedia broadcasting reception function separately performs a reception function for receiving a digital broadcast or a multimedia broadcast or a function of storing / playing back, and has been developed in a form that does not include a navigation and location information checking function. Therefore, the user has to select a variety of devices for the desired function, there is a disadvantage that the volume and cost increases, there is a disadvantage that the portability.

The present invention is to solve the above disadvantages and problems of the prior art, an audio / video storage and playback function that can cope with the convergence era in one portable multimedia player terminal, vehicle navigation system function using GPS, digital multimedia SUMMARY OF THE INVENTION An object of the present invention is to provide a digital multimedia broadcasting receiver having a media storage / playback and navigation function by providing a terminal apparatus having a broadcast receiving function to select and use a desired function.

According to an aspect of the present invention, there is provided an apparatus for receiving, storing, and reproducing digital multimedia broadcasting, comprising: an antenna for receiving an RF signal; A DMB receiving module for receiving a DMB signal input from the antenna; A GPS receiving module for receiving a GPS signal input from the antenna; A bridge connected to the DMB receiving module and the GPS receiving module; A CPU circuit unit for operating and controlling the entire apparatus; A memory circuit unit for storing navigation information from the GPS receiving module, DMB information from the DMB receiving module, and stored contents; An A / V circuit unit for decoding audio / video and outputting it externally; A display unit which displays the stored contents, navigation information from the GPS receiving module, and DMB information from a DMB receiving module; And a power management circuit section for generating, supplying, and managing power used in the apparatus.

Details of the above object and technical configuration of the present invention and the effects thereof according to the present invention will be more clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

1 is a schematic structural diagram of a digital multimedia broadcasting receiver of the present invention. As shown in FIG. 1, the present invention provides a terminal device having an audio / video storage and playback function, a vehicle navigation device function using GPS, and a digital multimedia broadcasting reception function that can correspond to an era of convergence. Can be selected and used.

1A shows a DMB receiving module and a GPS receiving module. The DMB receiving module and the GPS receiving module are connected to the antenna to receive an RF signal (DMB or GPS signal) and is connected to the system bus through the bridge 100.
