The present invention provides a system for providing traffic and travel information (TTI), more specifically, a system for providing traffic information to a vehicle driver using a digital multimedia broadcasting (DMB) service, and a method of using the system, In addition, the present invention relates to a DMB receiver using the system.

Recently, with the opening of digital multimedia broadcasting (DMB), various services using DMB have been developed. In particular, a big feature and advantage of the DMB is that it is possible to receive broadcasts on the go, so that the viewer can use the broadcast service wherever there is a DMB receiver. Due to the mobility characteristics of the DMB, a service for providing traffic and travel information (TTI) using a terrestrial DMB has recently been developed. This TTI service uses the international standard of Transport Protocol Expert Group (TPEG), and provides traffic and broadcasting information to customers who need traffic and travel-related information such as vehicle drivers through broadcasting in digital broadcasting systems such as DMB. It is.

The method of providing TTI data using the conventional TPEG structure is as follows. First, the terrestrial DMB broadcasting station processes predetermined traffic information, generates TTI data using a TPEG structure, and transmits it to a transmitting station. Then, the transmitting station receives TTI data to be transmitted by various terrestrial DMB receivers or vehicle navigation systems from a broadcasting station, and provides various traffic and travel information to a user such as a terrestrial DMB receiver. In this case, the TTI service is often a paid service, and therefore, a conditional access system (CAS) is used to ensure that only legitimate users who desire and pay for the TTI service can receive and verify the TTI data. do. The CA system typically modifies the signal form so that an unauthorized receiver cannot receive the original signal, and then transmits the modified signal to a terrestrial DMB receiver or a vehicle navigation system. In addition, a terrestrial DMB receiver or a vehicle navigation system employs a security module and a set-top box, which are usually present in the form of a smart card, to decrypt the received signal and reproduce the decrypted signal.

It is determined whether to provide (S205). If the member requests a predetermined software download and pays or promises to pay for the installation and / or use of the software (S206), the software manager 220 extracts the predetermined software from the software management DB 320. This is provided to the signal transceiver 240, and the signal transceiver 240 provides the software extracted through the web server 420 to the user side computer, terrestrial DMB receiver 700, etc. (S207). Meanwhile, before the software manager 220 extracts predetermined software and provides it to the signal transceiver 240, the encryption key generator 230 may assign an encryption key to each of the provided software. In this case, the software server 200 provides the terrestrial DMB receiver 700 with a decryption key capable of decrypting the encryption key simultaneously or separately with the provision of the software including the encryption key (S208). Therefore, when the software is installed in the terrestrial DMB receiver 700, the software can be installed after inputting a decryption key for decrypting an encryption key unique to each software. Alternatively, the decryption key may be provided to a third place other than a software server 200 such as, for example, a DMB server and may be provided to the terrestrial DMB receiver 700 from the DMB server.

On the other hand, as a result of confirming whether the software is provided as a user who is already using the predetermined software and wants to use other types of software (S209), the software management unit 220 extracts the corresponding software from the software management DB (320) This is provided to the signal transmission and reception unit 240, the signal transmission and reception unit 240 provides the software extracted through the web server 420 to the user side computer (S210). The present embodiment adopts a configuration that does not provide an encryption key and decryption key in this case, but it will be apparent to those skilled in the art that a configuration that provides an encryption key or the like may be adopted.

Next, a configuration of a traffic and travel information providing system according to a second embodiment of the present invention will be described below with reference to FIGS. 6 and 7. Hereinafter, components that perform the same functions as the first embodiment use the same reference numerals, and detailed descriptions thereof will be omitted.

FIG. 7 is a block diagram schematically illustrating a configuration of a traffic and travel information providing system according to a second embodiment of the present invention. The system includes a main server connected to a traffic information collecting server 500 and a DMB receiver 700. 20) and a DB server 300 'connected to the main server. 7 and 8, the main server 20 further includes a server 800 for authentication in addition to the configuration of the main server 10 according to the first embodiment, and the DB server 300 includes a first server. In addition to the configuration of the DB server 300 according to the embodiment further includes an authentication information DB (330). In addition, the authentication server 800 is composed of an authentication number issuing unit 810, a revocation number issuing unit 820 and a refund number processing unit 830.

Specifically, according to the second embodiment, the software provided from the software server 200 to the DMB receiver 700 is controlled by security means. That is, the software provided from the software server 200 to the DMB receiver 700 receives a user authentication by inputting a predetermined authentication number into the software, and performs a function of software for receiving and decoding encoded traffic and travel information data. Configured to do so.

The authentication number issuing unit 810 performs a function of issuing an authentication number for operating the software configured as described above. In the second embodiment, the authentication number issuing unit 810 is configured to include an authentication number generation module 811 for generating an authentication number and an authentication number encryption module 812 for encrypting the authentication number.

By the above configuration, the authentication number generation module 811 issues an authentication number for dismantling the security means of the software. The authentication number includes an issuing date of the authentication number, a unique number of each DMB receiver 700 in which the software is installed, a service period during which the security means are disassembled to receive data, and the data can be selectively provided. Contains service class information. The authentication number is a check bit for encrypting the authentication number, and a validity for checking the validity of the authentication number when the authentication number is input to the DMB receiver 700 later. It is preferably configured to further include a check bit. In addition, the authentication number encryption module 812 makes the authentication number configured as described above into one string, randomly selects the check bits, and encrypts the authentication number through the corresponding check bits. Subsequently, the authentication number is encrypted by generating a validity bit using the encrypted string and including the same in the string. The encrypted authentication number is transmitted to the user through, for example, the web server 420, and the user inputs the encrypted authentication number into the DMB receiver 700 by the method described later to remove the software whose security means is disassembled. It becomes available.

On the other hand, the transportation and travel information providing service according to the present invention is most often made of a fee, and therefore, issuance of such authentication number is made for the case where a predetermined fee is paid. Therefore, before issuing the authentication number, the authentication number issuing unit 810 checks the information on the paid payment, such as whether the user who requested the authentication number issuance has paid a predetermined service fee, if there is a request for issuing the authentication number. It is advisable to issue an authorization number only if the information has been verified. In addition, the paid payment does not necessarily need to be prepaid, and does not limit payment methods such as lump sum payment, post payment payment, monthly payment, and payment methods such as credit card, bank transfer, and gift certificate.

In particular, according to the present embodiment, since the authentication for using the software can be configured in various ways according to the predetermined period and the service level, the user can use the service according to the present invention more conveniently for his purpose.

Next, the termination number issuing unit 820 terminates the use of the service before the expiration of the period of use, despite the period of use permitted according to the authentication number input to the DMB receiver 700 in the manner described above and Likewise, it is operated upon termination of service. The revocation number issuer 820 includes a revocation number generation module 821 and a revocation number encryption module 822. The revocation number generation module 821 generates a revocation number for removing the previously entered authentication number and reactivating the software security means. The revocation number contains information such as the issue date of the revocation number, the unique number of each DMB receiver 700 in which the software is installed, and the remaining service period, similarly to the previous authentication number. It further includes a bit. In addition, the termination number encryption module 822 encrypts the termination number when the termination number generation module 821 is generated, for example, delivers it to the user through the web server 420, and the user will be described later. By inputting the encrypted revocation number to the DMB receiver 700, the security means of the software is activated again.

On the other hand, when the termination number is issued from the termination number issuing unit 820 described above and the use of the service is terminated, a problem of cost settlement may occur. That is, the traffic and travel information data according to the present invention is usually provided for a fee, so when canceled midway, a problem of cost settlement occurs.
