The present invention relates to a DMB receiver and a processing method for broadcasting a broadcast signal and traffic information together.

In particular, while receiving a video or audio signal from a predetermined ensemble that does not include traffic information, it receives traffic information provided by another ensemble and outputs it on one side of the screen where the video or audio information is being output. The present invention relates to a DMB receiver and a processing method for allowing information to be broadcast together.

DMB is a mobile multimedia broadcasting that can enjoy high quality voice (radio) and video service (TV) while moving. Promoted for the digitalization of radio, speed of about 380kbps is possible, so it can provide video service.

TV receivers could be installed in some conventional cars, but the problem of being stuck or interrupted due to poor radio wave reception rate is now being pursued by DMB. The DMB currently being tested is able to watch high-definition broadcasts without interruption.

DMB can be broadly divided into satellite DMB and terrestrial DMB, as shown in FIG. The terrestrial DMB is to catch and watch radio waves emitted from a transmission station like a general TV, and the satellite DMB is a method of spreading radio waves throughout the country through satellites.

The terrestrial DMB delivers various contents such as music, text, and video through portable terminals such as small TVs and PDAs due to its excellent mobile reception characteristics, and establishes a complementary relationship with digital terrestrial TV broadcasting to combine with mobile communication terminals. Services can create breakthrough demand.

The satellite DMB provides a multimedia broadcasting service including audio and additional data or video to a fixed, mobile, and portable receiver through a satellite. The satellite DMB provides various quality audio broadcasting services at low cost and uses a satellite to cover a large area. Coverage can dramatically expand the audible range of existing broadcasts.

The difference between the terrestrial DMB and satellite DMB is the same as the difference between general TV broadcasting and satellite TV broadcasting. In other words, terrestrial DMB can be viewed without paying, but satellite DMB has to pay a certain amount due to the satellite fee. In addition, satellite DMB has dozens to hundreds of channels while terrestrial waves have a limited number of channels.

In other words, satellite broadcasting transmits a video and audio signal produced by a broadcasting station through a transmitting earth station and transmits a signal to a receiving earth station in a distant place using a satellite, which is a low-orbiting satellite, as a repeater. The signal is transmitted to the satellite and the transmitted signal is received by the satellite and downstream through the S-band of 2 GHz to 4 GHz. Meanwhile, terrestrial broadcasting transmits video and audio signals produced by a broadcasting station to a repeater, and the transmitted video signals and the like are downstream through the L-band.

According to the current technology progress, you can enjoy high-definition broadcasting at home on HD TV, and watch DMB while traveling, that is, when driving in a car or watching on a PDA.

Such digital broadcast signals are received by mobile and fixed digital broadcast receivers so that a user can watch various videos.

The audio signal is output through the speaker 140, and the audio information related to the audio signal is output to the LCD interface 130 to be displayed on the screen.

On the other hand, when a user is curious about the current traffic information and inputs a traffic information reception request signal using a button or menu item provided in the DMB receiver, the controller 195 controls the traffic information to an ensemble that currently receives an audio signal or a video signal. Check to see if it contains.

As a result of the check, when the ensemble includes the traffic information, the controller 195 controls the TPEG decoding unit 160 to decode only the traffic information and outputs the traffic information to the data mixing processor 170, and the data mixing processor 170 outputs the data. The traffic information is output through the LCD interface 130 to output the traffic information on the screen.

On the other hand, if the traffic information is not included in the ensemble, the controller 195 controls the first tuner unit 110 to check which ensemble the traffic ensemble is included in. As a result, when an ensemble including traffic information is detected, the signal received from the ensemble is input to the DAB / DMB data extractor 125.

Then, the DAB / DMB data extractor 125 extracts DAB / DMB data from the received signal and outputs the DAB / DMB data to the TPEG decoding unit 160. The TPEG decoding unit 160 controls the DAB / DMB under control of the controller 195. Decodes only the traffic information from the DMB data and outputs the traffic information to the data mixing processor 170. The data mixing processor 170 outputs the traffic information through the LCD interface 130 to output the traffic information on the screen. do.

At this time, the control unit 195 is to be output to the traffic information is scrolled to the top or bottom of the screen, as shown in Figure 3 and 4, the traffic information is output while scrolling to the upper or left side. .

At this time, all the traffic information is processed and displayed in real time, whether by district or region.

(Navigation output method of DMB receiver)

Next, when the user selects a navigation menu item using a DMB receiver while driving the vehicle, the controller 195 outputs the map data stored in the map data storage unit 180 to the data mixing processor 160 to display the LCD interface unit 130. To be displayed on the screen.

Thereafter, the controller 195 calculates the current position value of the vehicle through the GPS processor 190 and displays the calculated position value on the upper part of the map so that the user can know.

When the navigation function is performed by the user, the traffic information is provided even when the user does not select it. That is, the controller 195 controls the first tuner 110 and the DAB / DMB data extractor 125 to output DAB / DMB data including traffic information to the TPEG decoding unit 160, 195 controls the TPEG decoding unit 160 to decode the traffic information and to output it on the screen through the data mixing processor 160.

Traffic information provided at this time includes traffic conditions, forecast conditions, estimated time of arrival, distance and time to the destination, calculation and display of optimal distance using real-time traffic conditions, and information of a specific area (for example, restaurant information, hotel information and reservations). , Parking lot information, etc.).

According to the present invention having the above-described configuration, operation, and preferred embodiments, the video or audio information is received by receiving a video or audio signal from a predetermined ensemble that does not include traffic information, and receives traffic information provided by another ensemble.
