The present invention relates to a DMB receiver having an MP3 broadcast data processing function and a processing method thereof.

In particular, the MP3 broadcast data processing function for providing convenience to the user by providing MP3 audio broadcast additional data in EPG format while receiving and outputting the MP3 broadcast included in the additional data broadcast using the DMB receiver. The present invention relates to a DMB receiver and a processing method thereof.

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 with excellent mobile reception characteristics, and establishes a complementary relationship with digital terrestrial TV broadcasting to be combined 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.

That is, satellite broadcasting launches video and audio signals produced by a broadcasting station through a transmitting earth station, and uses a satellite, a geostationary orbiting satellite, as a repeater and receives it on the receiver of the ground or through a gap filler in a shadow area where signals cannot reach. Will receive a signal. The signal is transmitted from the terrestrial digital broadcasting station to the satellite for digital broadcasting, 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 current technology progress, people will be able to enjoy high-definition broadcasts on their home HD TVs and watch DMB when they are on the go, such as driving in a car or watching a broadcast on their PDA.

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

In addition, many research institutes and companies are doing research and development to provide more services using the DMB receiver.

The present invention has been devised in response to the above research and development, and an object of the present invention is to receive and output MP3 type broadcast data included in supplementary data broadcast using a DMB receiver, and to output MP3 audio broadcast related additional data.

DMB dedicated A / V processing means for providing an EPG screen of MP3 audio data to be reproduced; Memory means for storing MP3 audio data decoded by the MOT decoding means; An MP3 player for storing MP3 audio data output through the MOT decoding means in the memory means and reading and playing the MP3 audio data stored in the memory means; An audio selector for outputting one of the first digital audio output output from the DAB / DMB decoding means and the second digital audio output and MP3 audio output output from the DMB dedicated A / V processing means; ; An audio DAC for converting a digital audio output output from the audio selector into an analog audio signal and outputting the analog audio signal; And main control means for controlling the entire system.

Another embodiment of the present invention provides a method of receiving and processing a DMB signal through a DMB receiver, wherein the main control unit checks whether the MP3 broadcast is selected by the user and requests the EPG display by the user when the MP3 broadcast is selected. A first step of determining whether a signal is input; The main control means may include a second step of outputting the EPG display screen through the LCD unit when the EPG display request signal is input; The main control means may include a third step of the user selecting a song through the EPG screen and checking whether a reservation recording request signal is input to the selected song; The main control means may include a fourth step of determining whether a song to be reproduced is a song for which reservation is requested by checking a header added before a frame of the reproduced MP3 audio data; And the main control means has a fifth process of storing MP3 audio data to be automatically reproduced when the song to be reproduced is a song for which reservation recording is requested.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation and preferred embodiment of the DMB receiver having the MP3 broadcast data processing function.

2 is a block diagram illustrating a configuration of a DMB receiver having an MP3 broadcast data processing function according to the present invention.

2, a DAB / DMB RF-tuner for tuning and filtering a specific channel with respect to a predetermined DMB signal input through an antenna in response to a control signal input from the main controller 160 to be described later. After performing channel decoding on the DMB signal input from the DAB / DMB RF-tuner unit 100 in response to the control signal input from the unit 100 and the main control unit 160, audio data and additional data. The MP3 audio data and the MP3 audio associated with the DAB / DMB audio decoder 110 to decode the additional data received from the DAB / DMB audio decoder 110 in response to a control signal input from the main controller 160. The MOT decoder 130 for decoding and outputting additional data, respectively, and the DAB / DMB audio decoder 110 in response to a control signal input from the main controller 160. The coded digital audio data is encoded and output to the speaker, and the EPG screen of the MP3 audio data to be reproduced through the MP3 player 140 is provided using the MP3 audio-related additional data output from the MOT decoder 130. The DMB dedicated A / V processing unit 120, the memory unit 150 storing MP3 audio data decoded by the MOT decoder 130, and the MP3 audio data output through the MOT decoder 130. The first digital audio output output from the MP3 player 140 and the DAB / DMB audio decoder 110 that are stored in the memory unit 150 and read and reproduce the MP3 audio data stored in the memory unit 150. And a second digital audio output and an MP3 audio output output from the DMB dedicated A / V processing unit 120 to output one selected according to the user's manipulation. Consists of a selector 180 and a main control unit 160 to the audio selector converts the digital audio output to be output as an analog audio signal the output audio DAC (190) to at 180, and controls the entire system.

The DMB dedicated A / V processing unit 120 encodes and outputs decoded data input from the DAB / DMB decoding unit by MPEG-4 in response to a control signal input from the main control unit 160, or inputs video data. It determines whether the MPEG-4 data or the H.264 AVC Baseline data is decoded and outputs the data through the TFT LCD 170.

The EPG screen includes one or more of a title of a song, a singer's name, a data amount per second, a total data amount, a broadcast time of the song, and profile data of the singer.

The main control means allows the user to select a song to record through the EPG screen, and checks the header portion of the song played through the MP3 player when the song to be recorded is selected and a recording reservation is made. If it is a song to be recorded, it is automatically recorded.
