摘要： A method is provided for performing handover by a terminal in a digital broadcasting system. The method includes measuring strength of a received signal from a serving broadcast transmitter while receiving a broadcast service, and comparing the measured strength of the received signal with a predetermined reference value; periodically measuring strength of the received signal while continuously receiving the broadcast service when the measured strength of the received signal is greater than the reference value; sending a handover start request message for the broadcasting system to a base station of a mobile communication system when the measured strength of the received signal is less than or equal to the reference value; and performing handover from the serving broadcast transmitter to a target broadcast transmitter upon receipt of an accept message for the handover start request for the broadcasting system from the base station.

摘要： A method and apparatus for transmitting and receiving an Electronic Service Guide (ESG) of an interaction channel in a Digital Video Broadcasting (DVB) system are provided. In order to transmit the ESG, ESG data about acquisition information is collected and it is determined whether a service associated with the ESG data is transmitted on an interaction channel. If the service is transmitted on the interaction channel, service access information needed to the interaction channel is set in a first field added for setting interaction channel information in an acquisition fragment of the ESG data. If the service is not transmitted on the interaction channel, service access information needed to receive a unidirectional broadcast channel is set in a second field configured to transmit information for accessing a service stream of the unidirectional broadcast channel in an old-version acquisition fragment. The ESG data including the acquisition fragment with the service access information set is transmitted to a receiving terminal.
