    • A first terminal subscribes to at least one service using a service guide in which information necessary for reception of each service is stored, and sends the service guide and an identifier (ID) of the subscribed service to a smartcard. The smartcard stores the service guide and the ID of the subscribed service, and sends the service guide and the ID of the subscribed service to a second terminal through a response message to a request message used for acquiring TBK information, received from the second terminal. The second terminal receives the response message by sending the request message to the smartcard, acquires TBK information corresponding to a service that the second terminal intends to play back, from the service guide depending on the subscribed service's ID included in the response message, and acquires the TBK by performing an authentication process using the TBK information.
    • 第一终端使用其中存储有用于接收每个服务所需的信息的服务指南来订阅至少一个服务,并将该订阅服务的服务指​​南和标识符(ID)发送到智能卡。 智能卡存储服务指南和订阅服务的ID,并且通过响应消息将服务指南和订阅服务的ID发送到第二终端,用于从第二终端接收到的用于获取TBK信息的请求消息。 第二终端通过向智能卡发送请求消息来接收响应消息,根据包括在响应消息中的订阅服务的ID从服务指南获取对应于第二终端打算重放的服务的TBK信息,并获取 TBK通过使用TBK信息执行认证处理。
