Abstract: A method for managing channels in a mobile multimedia terminal comprises receiving ensemble information associated with a multimedia channel, and identifying the multimedia channel into a plurality of services based on the ensemble information. The method also comprises identifying service components required for reception of the plurality of services. The method also comprises determining a service type of each of the plurality of services, and organizing the plurality of services based on service types. The organizing of the plurality of services based on the service types may further comprise receiving user service preference input from a user, and organizing the plurality of services based on the user service preference input.

Abstract: A method for decrypting digital multimedia broadcasting data in a mobile communication terminal. The method includes receiving encrypted digital multimedia broadcasting data though a broadcasting network, receiving at least one key for decrypting the encrypted digital multimedia broadcasting data through a wireless communication network, decrypting the received encrypted digital multimedia broadcasting data using the received at least one key, and displaying broadcast content that corresponds to the decrypted digital multimedia broadcasting data.

Abstract: The present invention relates to conditional access for receiving a broadcast service. The present invention comprises requesting reception of a service from a wireless cellular communication network, receiving at least one encryption key from the wireless cellular communication network for decrypting encrypted service data, wherein the at least one encryption key is generated by a non-cellular broadcast station, receiving the encrypted service data from the non-cellular broadcast station, the encrypted service data having at least one encryption key, decrypting the encrypted service data if the at least one encryption key received from the wireless cellular communication network matches the at least one encryption key of the encrypted service data, and providing the decrypted service data. Preferably, fee charging information related to providing the decrypted service data is monitored and provided to a fee charging authority to allow a fee to be charged based on the fee charging information.
