    摘要： Two different communication terminals share a broadcast content received through a mobile broadcast service. If a mobile broadcast-sharing mode for sharing a broadcast content with a specific communication terminal is set, a mobile broadcast terminal extracts broadcast video data and broadcast audio data from a mobile broadcast signal being received. The mobile broadcast terminal converts a codec of the broadcast video data and the broadcast audio data into a codec used in video communication, and delivers at least one of the converted broadcast video data and the converted broadcast audio data through video communication formed to the communication terminal.

    摘要： Disclosed is a method and a digital broadcasting system for transmitting and receiving an Electronic Service Guide (ESG). When there are ESG fragments to be transmitted through a communication network among ESG fragments included in ESG data, a digital broadcast transmitter generates an ESG data session such that the ESG data session may include route information through the communication network of the relevant ESG fragments. Then, the digital broadcast transmitter transmits the generated ESG data session to a broadcast receiving terminal, which obtains the route information through the communication network of the relevant ESG fragments. Accordingly, a user can more easily and conveniently receive the ESG data by using the route information through the communication network obtained by the broadcast receiving terminal.

    摘要： An apparatus and a method reduce delay when reproducing digital broadcasting in a mobile terminal. More particularly, the apparatus and method reduce a reproduction delay, from having to stand by until an encrypted stream that matches with a traffic key is received, by receiving the traffic key in advance prior to the encrypted stream when a mobile terminal receives encrypted broadcasting. The apparatus includes a controller. The controller receives and stores a traffic key corresponding to an encrypted channel even when not entering the encrypted channel, and deciphers and reproduces the relevant channel using the stored traffic key when entering the encrypted channel.

    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.
