The present invention relates to a terminal capable of receiving digital multimedia broadcasting (DMB), and more particularly, to a connection technology for purchase of goods related to broadcasting.

The conventional advertising method through a mobile terminal was a method of directly calling a terminal user or randomly delivering an advertisement content through a text message (SMS). In this case, the advertising effect is not high because it has a one-sided advertisement form that ignores the taste of the terminal user or the current situation of the user, and it is used because the terminal user is repeatedly interrupted in the daily life of the terminal user. There is a problem that causes the discomfort of the party, rather causing the adverse effect of advertising.

And in the case of advertisement through broadcasting, it can naturally induce the interest and interest of the listener during the listening of the advertisement, but in order to be connected to the actual purchase, the listener remembers the product and visits the store later, or calls after the advertisement. Alternatively, there is an inconvenience in that a product must be purchased using a second medium different from a broadcast transmission medium such as an internet medium.

SUMMARY OF THE INVENTION The present invention was derived from this background, and an object of the present invention is to provide a technical method of directly connecting an order for a product related to a broadcast while listening to a broadcast through a DMB terminal having a telephone and a DMB reception function.

In accordance with an aspect of the present invention, there is provided a method for connecting a broadcast product purchase of a DMB terminal to obtain a telephone number associated with a broadcast played during playback by receiving an audio broadcast of a T-DMB, and obtaining a user command if there is a user command. The call to the phone number that was dialed.

In accordance with this aspect of the present invention, the broadcasting product purchase connection method of the DMB terminal according to the present invention obtains an advertisement product purchase connection telephone number related to broadcasting so that a call connection can be performed immediately, thereby allowing the terminal user to listen to the broadcast. Provides the convenience of making a phone order for an advertising product immediately.

The foregoing and further aspects of the present invention will become more apparent through the preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

1 is a schematic diagram of a terrestrial DMB system. The terrestrial DMB center 10 transmits terrestrial DMB (T-DMB) by applying a CDM modulation scheme using S-band. As is known, T-DMB provides audio services, video services, and data services. Here, the audio service of the T-DMB refers to the audio service of FM or AM radio, unlike the audio signal of the video service, and the present invention relates to the audio service.

The terrestrial DMB center 10 according to the present invention transmits audio data by including connection telephone number data to receive an order when an advertisement product is related to the broadcast content. This is provided by X-PAD (eXtended Program Association Data) of T-DMB's audio stream service and uses DLS (Dynamic Label Segment) made to provide additional services such as song title, singer information and traffic information. It can be achieved by carrying along with the purchase connection phone number of the advertisement product currently being broadcast on the PAD. At this time, the telephone number on the X-PAD preferably has a predefined format so that the DMB terminal 30 can recognize it as a commodity purchase connection telephone number.

The DMB terminal 30 receives and processes the T-DMB audio broadcast transmitted from the terrestrial DMB center 10 through the repeater 20. The processing method converts the received digital audio broadcast signal into a baseband orthogonal signal as known, performs demodulation on the OFDM modulation from the converted orthogonal signal, restores the frequency interleaving signal for error correction, and DQPSK encoding. After the decoded signal is decoded, interleaving with respect to time is restored, and the Viterbi coded one is decoded. In addition, the channel decoder decodes the audio information, decodes it according to the MPEG-1 / 2 Layer 2 compression method, generally called MUSICAM, and outputs it through an audio D / A converter and a speaker. Since the configuration itself of the terminal for receiving and processing the audio broadcast of the T-DMB is a well-known matter, a detailed description thereof will be omitted.

The DMB terminal 30 according to the present invention extracts the telephone number included in the audio stream of the T-DMB and informs the user so that the call connection can be performed according to a user command. This will be described with reference to FIG. 2. 2 is a flowchart illustrating a broadcast product purchase connection method of the DMB terminal 30 according to the present invention. As shown, receiving and reproducing an audio broadcast of T-DMB, obtaining a telephone number associated with the broadcast being reproduced, and performing a call connection with the obtained telephone number according to a user command .

The DMB terminal 30 receives the T-DMB audio broadcast and reproduces it through the above-described processing (step S200). Then, the X-PAD (eXtended Program Association Data) included in the audio frame is checked (step S210). 3 is a structural diagram of an X-PAD included in an audio frame. In step S210, the DMB terminal 30 checks the X-PAD using the F-PAD shown in FIG. 3 as known when receiving the audio broadcast. The DMB terminal 30 confirms the application type by checking the contents identifier (CI) of the identified X-PAD (step S220). If the application type is 2 or 3, the DMB terminal 30 recognizes that it is a dynamic label segment (DLS) protocol (step S230).

The DLS protocol is a data transmission protocol for providing a song title, singer information, traffic information, etc. by providing the X-PAD of an audio stream service. 4 is a service model structure diagram of T-DMB. From FIG. 4, the location of the DLS protocol included in the audio service can be confirmed. The DLS protocol is included in the audio frame and serviced. The basic structure is shown in FIG. 3. X-PAD uses CI to distinguish transport protocols such as Dynamic Label Segment (DLS), Multimedia Object Transfer (MOT), and Transparent Data Channel (TDC). For reference, CI values are 2, 3 for DLS, 11, 12, 13, and 14 for MOT, and 23 for TDC.

In the case of the DLS protocol, the DMB terminal 30 parses the data contained in the X-PAD and checks whether the data content has a product purchase connection telephone number format (step S240). Preferably, the telephone number that is loaded for the purchase connection of the product currently being broadcasted to the corresponding X-PAD using the DLS protocol has a predefined format so that the DMB terminal 30 can recognize the product purchase connection as the telephone number. . Therefore, the DMB terminal 30 may identify whether the product purchase connection telephone number format is defined in advance and distinguish whether or not the data contained in the X-PAD is the product purchase connection telephone number.

If the data loaded in the X-PAD is a product purchase connection telephone number, the telephone number is stored in a temporary buffer. And preferably, the DMB terminal 30 informs the user that there is a product purchase connection telephone number (step S250). According to an example, the method of notifying the user may display a phrase indicating that there is a product purchase connection phone number on the terminal screen, or may be performed by voice output. Accordingly, the terminal user may know that there is a connection telephone number for ordering a product related to the audio broadcast currently being listened to. Accordingly, if the terminal user wants to order a product, the terminal user commands a telephone connection through a key operation. The DMB terminal 30 confirms that there is a telephone connection command from the terminal user (step S260), and performs call processing as known to make a call to the telephone number carried in the X-PAD (step S270). ). When a call is connected, the terminal user places a product order through a call with a receptionist.

As described above, the broadcasting product purchase connection method of the DMB terminal according to the present invention obtains an advertisement product purchase connection telephone number related to broadcasting and performs a call connection immediately. Provides convenience to place phone orders immediately.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
