摘要： An access point (AP) for ensuring a Quality of Service (QoS) of a broadcasting service in a Wireless Local Area Network (WLAN) is provided. A broadcast signal input unit receives a broadcast signal and depacketizes the received broadcast signal into a transport stream. A broadcast signal control unit receives channel selection information of a terminal, creates a zapping signal (protocol) and a control signal using bandwidth information to control a broadcast signal. A broadcast signal switching unit selectively receives the transport stream using the zapping signal, stores the received transport stream for a predetermined amount of time, and outputs the stored transport stream to the broadcast signal control unit through time slicing using the control signal.

摘要： Disclosed is a broadcast splitter enabling a selective transmission in real time. The broadcast splitter divides one multi-program transport stream (MPTS), which is obtained by multiplexing motion picture expert group-2 transport streams (MPEG-2TSs), into several single program transport streams (SPTSs). In particular, the broadcast splitter for MPEG-2TSs has a function of selecting a desired SPTS by performing a switching operation with respect to an MPTS in real-time without storing the MPTS when the MPTS is split into several SPTSs. Accordingly, it is possible to transmit MPTS signals in real time because desired TSs are extracted and delivered to output ports in real time by using a broadcast switch without storing the MPTS signals in a storage unit such as a RAM.

摘要： A method for setting a multicast and broadcast service (MBS) of a broadband wireless access system includes: previously receiving and storing the information on the MBS setting from a MBS server by a radio access station; and broadcasting the information on the MBS setting stored in the PSS, which exists in the service area of the radio access station, by the radio access station. In the step of broadcasting the information on the MBS setting, a preset pilot tone, uplink/downlink information, or the sub-carriers unused in bandwidth of the system are used for broadcasting the information.
