    • A method for providing traffic information and a method and an apparatus for using the same are provided to create a profit by encoding and transmitting data using an encryption key in order to restrict the reception and usage of the data and providing a module to decode the data. A control part receives encoded data containing traffic information through a broadcasting module(S802). The control part extracts an IMW(Initialization Modifier Word) and a conditional access CW(Control Word) from the received data(S804). Using the IMW and the conditional access CW, the control part creates a decoding CW(S806). Then the control part decodes the encoded data using the created decoding CW and acquires the traffic information(S808). Finally the control part outputs the acquired traffic information through an LCD part(S810).
    • 提供一种用于提供交通信息的方法及其使用方法和装置,以通过使用加密密钥对数据进行编码和传输创造利润,以限制数据的接收和使用,并提供对数据进行解码的模块 。 控制部通过广播模块接收包含交通信息的编码数据(S802)。 控制部分从接收到的数据中提取IMW(初始化修改词)和条件访问CW(控制字)(S804)。 使用IMW和条件访问CW,控制部分创建解码CW(S806)。 然后,控制部分使用创建的解码CW对编码数据进行解码并获取交通信息(S808)。 最后,控制部通过LCD部输出获取的交通信息(S810)。

    • A method for offering and using public traffic information and a device are provided to offer information on operation situations of public traffic systems to a user using the public traffic systems, and to enable the user to purchase a ticket in advance right after searching the information through a wireless communication network. A controller extracts bus service route information and location information from a TPEG(Transport Protocol Expert Group) message received from a traffic information supply server, and decodes the extracted information(S1102). The controller displays the decoded bus service route information on an LCD(Liquid Crystal Display)(S1104). The controller decides whether a provided ticket pre-purchase menu is selected by a user(S1106). If so, the controller enables the user to access an Internet site through a wireless communication channel by using a URL(Uniform Resource Locator) included in additional information(S1108).
    • 提供和使用公共交通信息的方法和设备被提供以向使用公共交通系统的用户提供关于公共交通系统的操作情况的信息,并且使得用户能够在搜索信息之后提前购买机票 无线通信网络。 控制器从从交通信息提供服务器接收到的TPEG(传输协议专家组)消息中提取总线业务路由信息和位置信息,并解码所提取的信息(S1102)。 控制器在LCD(液晶显示器)上显示解码的总线服务路线信息(S1104)。 控制器决定用户是否选择所提供的票据预购菜单(S1106)。 如果是这样,则控制器使用户能够通过使用附加信息中包含的URL(统一资源定位器)通过无线通信信道来访问因特网站点(S1108)。

    • A method for offering a DRM(Digital Rights Management) file download service is provided to enable a user to easily decode/play a DRM file in a device like a car audio device difficult to connect with a PC by making a content providing server generate/provide the DRM file encoded as the file playable in the device after checking information for the device to play the DRM file. The content providing server checks the information of the device to download/play the DRM file(S11). The content providing server provides the DRM file encoded as the file playable in the corresponding device based on the checked device information(S13). The content providing server receives and checks the information of the device through an interface with a device information server after checking a device serial number received through the PC connected to the Internet. The PC downloads the DRM file and transfers the DRM file to the device according to a user request, and the device decodes/plays the DRM file by using the serial number.
    • 提供了一种用于提供DRM(数字版权管理)文件下载服务的方法,以使用户能够通过使内容提供服务器生成/播放文件来容易地解码/播放像难以与PC连接的汽车音响设备的设备中的DRM文件, 在检查设备播放DRM文件的信息之后,提供被编码为可在设备中播放的文件的DRM文件。 内容提供服务器检查设备的信息以下载/播放DRM文件(S11)。 内容提供服务器基于所检查的设备信息,提供被编码为可在相应设备中播放的文件的DRM文件(S13)。 内容提供服务器在检查通过连接到因特网的PC接收到的设备序列号之后,通过与设备信息服务器的接口来接收并检查设备的信息。 PC下载DRM文件,并根据用户请求将DRM文件传输到设备,设备使用序列号解码/播放DRM文件。
