Abstract: A method of channel assessment and channel searching in a wireless network is disclosed. The wireless network separately performs a channel assessment procedure and a channel searching procedure for channel change or another object. The channel assessment procedure is to measure a status or quality of a channel which is currently used in the wireless network. A coordinator of the wireless network designates a time interval for the channel assessment to notify other device of it. The channel assessment procedure may be performed periodically, and is preferably scheduled to allow other devices not to use the channel for the time interval which at least one device performs channel assessment.

Abstract: A broadcast receiver and a method of processing data are disclosed. The broadcast receiver includes a signal receiving unit, a transmission parameter detector, a block decoder, a storage unit, and a data manager. The signal receiving unit receives a broadcast signal multiplexed mobile broadcast service data including two-way contents and main broadcast service data. The transmission parameter detector detects the transmission parameter. The block decoder symbol-decodes the received broadcast signal included in the mobile broadcast service data in block units, based upon the detected transmission parameter. The storage unit stores the decoded two-way contents. The data manager reads a requested two-way contents from the stored two-way contents with respect to a user's select signal, and provides the requested two-way contents service.
