ABSTRACT:
Disclosed is a channel time allocation method in a high rate WPAN and a wireless system using the same. In the WPAN environment synchronized by a synchronization signal broadcasted from a coordinator, the channel time allocation method includes transmitting a channel time allocation request command corresponding to a property of an application data to be transmitted to the coordinator by any one of devices linked to the WPAN, and the coordinator allocating the channel time, inserting information of the allocated channel time to the synchronization signal, and broadcasting the synchronization signal to the devices. Accordingly, the channel time is allocated to fit for the property of the VBR stream data such as the MPEG-2 video so that the QoS of the VBR stream is provided. At the same time, reliability of the transmission of I frame is enhanced so that success rate of decoding the frame is increased.
