Abstract: A broadcast receiver receives a packetized stream. The broadcast receiver extracts display time information from the header of the received packetized stream, and extracts preparation trigger information including a target service identifier from the payload of the received packetized stream. If a current time is a preparation time designated by the extracted display time information, the broadcast receiver starts to prepare an object corresponding to the target service identifier for activation at a later time.

Abstract: Provided are a method and a device for transmitting and receiving a traffic stream in a wireless local area network (WLAN) system. Specifically, the device broadcasts a beacon frame including allocation information on a contention-free period (CFP) and allocation information on a contention period (CP) to a station (STA) and transmits a downlink traffic stream to the STA or receives an uplink traffic stream from the STA, based on the allocation information on the CFP. The allocation information on the CFP indicates that the downlink traffic stream is transmitted without performing a clear channel assessment (CCA) during the CFP and indicates that the uplink traffic stream is received with performing a CCA during the CFP.
