Access point for ensuring quality of service of broadcasting service in wireless local area network

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.
