摘要： An ONU includes a CDR that regenerates a clock based on a signal from an OLT, an oscillator that generates an internal clock, a time stamp counter that manages a time of the ONU based on the clock in a period in which the CDR regenerates the clock and manages the time of the ONU based on the internal clock in a period in which the CDR does not regenerate the clock, an MPCP control unit that decides, when a Cyclic Sleep mode is set, a receiver-time synchronization time that is a period in which the receiver is normally operated within a sleep time, based on a difference between a time stamp value included in the signal transmitted from the OLT and a time stamp managed by the time stamp counter, and a power-saving control unit that controls the receiver to be normally operated in the receiver-time synchronization time.

摘要： In a method for exchanging data in messages between users of a CAN bus system, the users have their own time bases; a first user functioning as timer transmits a reference message having a specifiable identifier via the bus, which includes a first time information with regard to the time base of the first user; the at least second user, using its time base forms its own second time information as a function of the first time information of the first user in such a way that, from the deviation of the first and the second time information a correction value is ascertained, so that from the first time information of the first user as the timer, the global time for the bus system is yielded.

摘要： A data conversion system for converting data outputted from an information processor into data in a different format in real time while preventing any defect of an image such as frame missing or frame repetition of moving image data by synchronizing data transfer with converted data output. One of first and second nodes on an IEEE1394 bus functions as a cycle master, and first data is transferred from the first node to the second node in synchronism with a cycle start packet outputted from the cycle master. Second data generated by converting the first data by the second node is outputted in synchronism with a reference signal inputted from outside. The system comprises an external synchronizing signal receiving section provided at least in one of the first and second nodes and adapted to receive the reference signal inputted from outside and a synchronism control section for synchronizing the frequency of a cycle start packet outputted from the cycle master with the reference signal received by the external synchronizing signal receiving section.

摘要： The present invention discloses a method and system for accurate time transfer in PON. An Optical Line Terminal (OLT) ranges Optical Network Units (ONUs) and obtains ranging information, then, triggered by the periodic Pulse per n Second (PPnS), generates a PPnS timestamp based on the local reference counter and the Time of Day (TOD) above second; OLT transmits the ranging information, the periodic PPnS timestamp and TOD to ONUs; ONUs predicts the time of the next second according to said periodic PPnS timestamp, TOD and ranging information, and outputs the corresponding PPnS. The invention is characterized by the combination of the features of PON point to multi-point and PON ranging into its time transfer method, the high accuracy of time transfer, and the low hardware costs for OLT and ONU, as well as the extremely small bandwidth occupancy.

摘要： A communication protocol over the serial bus allows a peripheral device to control the flow of data between a host computer and the peripheral device so as to maintain synchronization to a periodic reference signal. The protocol involves transferring flow control messages between the peripheral device and the host computer, allowing the peripheral device to control how and when the host computer sends the uncompressed audio and video data.

摘要： A number of features for enhancing the performance of a communication system, in which data is transmitted between a base station and a plurality of subscriber stations located different distances from the base station, are presented. The power transmission level, slot timing, and equalization of the subscriber stations are set by a ranging process. Data is transmitted by the subscriber stations in fragmented form. Various measures are taken to make transmission from the subscriber stations robust. The uplink data transmission is controlled to permit multiple access from the subscriber stations.
