Abstract
Disclosed is a DVB-H CBMS system by which a user can continue to view a program being in service even when the transport stream or IP platform changes while the user views the program. In the DVB-H CBMS system, the system transmits service mapping information according to transport streams or IP platforms to the terminal, so that the system can provide a service without interruption to the terminal even when a user of the terminal moves out of a current cell or network into a new cell or network while receiving a service that the user selected.
Claims20
A terminal for receiving a broadcast service in a mobile Digital Video Broadcasting-Handheld (DVB-H) Convergence of Broadcasting and Mobile Service (CBMS) system, the terminal comprising:
- a broadcast receiver for receiving, from a broadcast network, a specific broadcast service that is commonly provided through a plurality of Internet Protocol (IP) platforms existing in a single transport stream, the specific broadcast service comprising Program Specific Information/Service Information (PSI/SI) for the specific broadcast service including mapping information between the plurality of IP platforms that identifies different service IDentifiers (IDs) allocated to the specific broadcast service provided through the respective IP platforms;
- and
- a mobility manager for managing movement to another network by checking the mapping information to identify at least one of the IP platforms providing the specific broadcast service identified by at least one of the different service IDs.
A method for receiving a broadcast service by a terminal in a mobile Digital Video Broadcasting-Handheld (DVB-H) Convergence of Broadcasting and Mobile Service (CBMS) system, the method comprising the steps of:
- receiving, from a broadcast network, a specific broadcast service that is commonly provided through a plurality of Internet Protocol (IP) platforms existing in a single transport stream, the specific broadcast service including Program Specific Information/Service Information (PSI/SI) for the specific broadcast service including mapping information between the plurality of IP platforms that identifies different service IDentifiers (IDs) allocated to the specific broadcast service provided through the respective IP platforms;
- and
- managing movement to another broadcast network by checking the mapping information to identify at least one of the IP platforms providing the specific broadcast service identified by at least one of the different service IDs.
