Abstract
An apparatus and method for receiving a multimedia broadcasting service in a mobile communication system including a satellite digital multimedia broadcasting (DMB) reception system and a terrestrial DMB reception system. In the apparatus, a satellite DMB modem block demodulates a satellite broadcast signal received from the satellite DMB system. A terrestrial DMB modem block, sharing at least one function block with the satellite DMB modem block, demodulates a terrestrial broadcast signal received from the terrestrial DMB system. A Motion Picture Experts Group (MPEG) decoder separately decodes MPEG transport streams (TSs) for the satellite broadcast signal and the terrestrial broadcast signal.
Claims18
An apparatus for receiving a multimedia broadcasting service in a mobile communication system including a satellite digital multimedia broadcasting (DMB) system and a terrestrial DMB system, the apparatus comprising:
- a satellite DMB modem block for demodulating a satellite broadcast signal received from the satellite DMB system;
- a terrestrial DMB modem block sharing at least one function block with the satellite DMB modem block, for demodulating a terrestrial broadcast signal received from the terrestrial DMB system;
- and
- a Motion Picture Experts Group (MPEG) decoder for separately decoding MPEG transport streams (TSs) for the satellite broadcast signal and the terrestrial broadcast signal.
A method for receiving a multimedia broadcasting service in a mobile communication system including a satellite digital multimedia broadcasting (DMB) system and a terrestrial DMB system, the method comprising the steps of:
- receiving a satellite broadcast signal of the satellite DMB system and a terrestrial broadcast signal of the terrestrial DMB system, from a wireless network;
- modifying a header of a first Motion Picture Experts Group (MPEG) transport stream (TS) for the terrestrial broadcast signal with a predetermined value being different from that of a header of a second MPEG TS for the satellite broadcast signal;
- and
- separately MPEG-decoding the first MPEG TS for the terrestrial broadcast signal and the second MPEG TS for the satellite broadcast signal.
