Abstract: An apparatus and method for managing a preference channel are provided which can reduce a delay time when a channel change is made between preference channels, by storing a preference channel directly selected by a mobile terminal user in a mobile broadcast system. A mobile terminal receives and demultiplexes multiplexed logical channels on which data streams are transmitted from a service provider through a communication network. Preference channels of the demultiplexed logical channels are dynamically allocated to decoding buffers using stored information. A decoding time at which data of the decoding buffers is accessed and decoded is computed using reference information. A decoding operation is performed at the computed decoding time, and decoded channel-by-channel elementary streams are stored in a memory. The decoded channel-by-channel elementary streams stored in the memory are displayed on a screen of the mobile terminal.

Abstract: A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.
