摘要： Provided is a method of efficiently processing a Short-Term Key Message (STKM) in the mobile broadcast supporting the mobile terminal. A structure of a response message according to processing the STKM in the smart card is also provided. In particular, a variety of information necessary for reproducing in the player is included in the response message and delivered to the mobile terminal, thereby the mobile terminal can easily obtain the desired information through the response message. Therefore, when the STKM is processed in the mobile terminal, there is no need to process operations except for a resending check, and the information does not need to be stored separately.

摘要： A mobile terminal is configured to acquire an encryption key to decrypt a pay channel encrypted with a smartcard profile by the mobile terminal in a Multimedia Broadcast/Multicast Service (MBMS) mobile broadcast system. The mobile terminal is configured to purchase a specific pay channel, determine validity of an encryption key, store a range of a valid encryption key identification value, and initialize a reference Time Stamp (TS) value. The mobile terminal also; extracts an encryption key identification value and a TS value from a last received Short Term Key Message (STKM), when a view request for the specific pay channel is created; and determines that an encryption key is valid, when the extracted TS value satisfies the reference TS and the extracted encryption key identification value falls within a range of the valid encryption key identification value, and extracts and acquires an encryption key from the STKM.

摘要： Disclosed is a system and a method for providing a terminal with a notification message reporting changes of a system and of a service in the middle of a Digital Video Broadcasting-Handheld (DVB-H) broadcasting service. The system inserts channel information related to the transmission of the notification message into Electronic Service Guide (ESG) service fragment or ESG acquisition fragment, then transmits the inserted channel information, or specifies a notification session for a session to transmit the session. In this manner, the channel information related to the notification message can be transmitted to a terminal through an ESG, and the terminal acquires the channel information related to the notification message from the received ESG to receive the notification message by using the channel information.

摘要： Disclosed is a method for providing heterogeneous services using a PIP function in a terrestrial DMB receiver. The method includes: a first step of receiving a key input for activating the PIP function and displaying a list of services in an available ensemble during use of a desired DMB service; a second step of selecting a desired item in the list of services; a third step of identifying if the desired item selected at the second step is an “exchange” function and identifying if PIP function of the terrestrial DMB receiver is activated when the selected item is the “exchange” function; a fourth step of exchanging a service of a main screen for a service of a PIP screen, when it is identified that the PIP function is activated at the third step; and a fifth step of identifying if the desired item selected at the second step is the “exchange” function and displaying the selected item on the PIP screen when the selected item is not the “exchange” function.

摘要： Disclosed is a method and a system for broadcasting an Electronic Service Guide (ESG) for digital broadcasting, which includes predetermined change information, when important information of the ESG is changed in a digital video broadcasting system. A digital broadcasting apparatus broadcasts an ESG that includes current information data and predetermined change information through a broadcasting communication network. A digital broadcasting reception terminal receives and stores the broadcasted ESG, provides a digital broadcast service based on the current information data of the ESG and provides a digital broadcast service based on the stored predetermined change information data after a prescheduled ESG change time point.
