    • PURPOSE: A broadcast system for providing a connection service between a DTV and a DMB is provided to supply an additional service about the DTV using the DMB. CONSTITUTION: A DTV receiving module(210) uses a DTV service list using a DTV frequency band. A DMB receiving module(220) uses a DMB service list using a DMB frequency band. A control module(230) combines the DTV service list with the DMB service list. The control module generates an integration service list of a DTV and a DMB. The control module transmits a DTV frequency scan command to the DTV receiving module, extracts PSIP information from data which are transmitted from the DTV frequency band according to the DTV frequency scan command, and transmits the PSIP information to the control module as the DTV service list.

    • PURPOSE: A buffer management device for reproducing streaming multimedia and a method thereof are provided to consecutively reproduce the streaming multimedia when a handover process is executed in a wireless network. CONSTITUTION: A control unit(440) determines the handover of a first wireless network from a second wireless network. A second network reception unit(420) receives delay multimedia data. The second network reception unit buffers the received delay multimedia data to a second buffer. A decoding buffer(430) provides the delay multimedia data buffered to the second buffer by receiving data. A first network reception unit(410) receives the multimedia data. The first network reception unit buffers the received multimedia data to the first buffer.
