  • Patent number: 10264553
    Abstract: A method and apparatus for transmitting a broadcast signal are provided. Data of data packets is encoded to add first parity data to the data packets. The data packets include broadcast data and signaling data for a service. The signaling data includes type information indicating a type of the service and channel information of the service. Information for acquisition of the signaling data is predefined. The encoded data is block interleaved. The block-interleaved data is convolutional interleaved. Transmission parameters are first encoded for signaling the broadcast data to add second parity data to the transmission parameters, and the first-encoded transmission parameters are second encoded at a code rate. A frame including the convolutional interleaved data and the second-encoded transmission parameters is built. The broadcast signal including the frame is transmitted. The transmission parameters include information for identifying a number of the first parity data.

  • Patent number: 9743382
    Abstract: A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes a first receiving unit, a second receiving unit, a known sequence detector, a equalizer, and a display unit. The first receiving unit receives a first broadcast signal including first mobile broadcast service data and first main broadcast service data. The second receiving unit receives a second broadcast signal including second mobile broadcast service data and second main broadcast service data. The known sequence detector detects at least one of known data included in the received first broadcast signal and known data included in the received second broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received first and second mobile broadcast service data corresponding to the detected known data.

  • Publication number: 20160248566
    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.

  • Patent number: RE46509
    Abstract: A wireless network includes a current coordinator, at least one device which is currently associated with the wireless network, and a device selected as a new coordinator among the at least one device by the current coordinator. The current coordinator transmits a handover request message to the new coordinator; receives a handover response message in response to the handover request message from the new coordinator, the handover response message including a reason code field that is set to “success”; and broadcasts one or more beacons, each beacon including identification information which identifies the new coordinator and number information which indicates a number of remaining beacons that the current coordinator will broadcast before a handover occurs. The number information included in a last beacon among the one or more beacons is set to “0,” and the new coordinator broadcasts a beacon after receiving the last beacon from the current coordinator.
