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:
An apparatus and method for transmitting a plurality of key data. When a Short-Term Key Message (STKM) is received, a mobile equipment transmits the received STKM to a smart card. The smart card determines whether there are a plurality of key data in the STKM, detects the plurality of key data when there are the plurality of key data, generates individual information for identifying each of the plurality of detected key data, generates a response message having the plurality of detected key data and the generated individual information, and transmits the response message to the mobile equipment. Therefore, a plurality of key data can be included and transmitted in one message.

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.

Provided are an apparatus and a method for displaying file download information in a Digital Video Broadcasting (DVB) terminal. The method includes receiving an Electronic Service Guide (ESG) data stream containing information regarding downloadable files, analyzing the downloadable file information in the ESG data stream, storing the downloadable file information in the memory module, and if a file download service is selected by a user, displaying the downloadable file information on the display unit, if downloading of at least one file is selected, examining download-related information using the stored file information corresponding to each file when the selected files are downloaded, and creating a download file list containing each file name and the download-related information examined corresponding to each file and displaying the download file list on a screen.

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.

Disclosed is a method for providing information regarding service linking between a terrestrial DMB system and a satellite DMB system by using a service linking information provision server for creating and providing service linking information between the terrestrial DMB system and the satellite DMB system in a broadcasting having the terrestrial DMB system, the satellite DMB system, and a mobile communication system. The method includes the steps of (a) receiving EPG information from the terrestrial DMB system and the satellite DMB system, respectively, by the service linking information provision server; (b) analyzing content of the EPG information and confirming existence of a linked service; (c) classifying service linking according to degree of linking, when the existence of a linked service is confirmed, and storing resultant classification information as service linking information; and (d) providing the service linking information via the mobile communication system when a request for the service linking information is received from a DMB receiver terminal.
摘要:
A dual mode Digital Multimedia Broadcasting (DMB) terminal for simultaneously receiving signals of satellite and terrestrial DMB broadcasting stations includes a satellite DMB receiver for receiving and demodulating the satellite signals, and outputting a satellite MPEG 2-TS, and another receiver for analogously processing terrestrial signals. A classification unit switches the two types of MPEG 2-TSs, and outputs the switched MPEG 2-TS to a broadcasting information display unit or an MPEG 2-TS output unit. The first unit generates TAG information, and inserts it into the MPEG 2-TS. A storage unit saves the MPEG 2-TS. The MPEG 2-TS output unit decodes and outputs the MPEG 2-TS. A controller transfers selection information for a switching operation of the DMB classification unit, and transfers information on a decoding scheme.
