摘要： Transmission delays due to the buffering of data packets are registered for the purpose of regulating a jitter buffer. Weighted mean delay values are continuously derived from registered transmission delays, with a shorter transmission delay receiving a higher weighting than a longer transmission delay. A read-out speed of the jitter buffer is then regulated as a function of the continuously derived weighted mean delay values in such a way that the weighted mean delay values are adjusted as a regulating variable to a predefined desired delay.

摘要： At member registration step, a master transmits a certificate and a priority to a slave. The certificate indicates that the slave receiving it belongs to the same data synchronization group as the master. The priority is used to solve a data conflict. At data synchronization step, after it is determined that members belong to the same data synchronization group by the certificate, data synchronization processing is performed between arbitrary members in which an input device and a display device such as wrist watch are limited. Data synchronization does not require a specific server.

摘要： A system and method for establishing a known timing relationship between two clock signals, wherein a first clock signal is operable to clock data transfer operations from a transmitter domain to a receiver domain and a second clock signal is operable to be transported to the receiver domain. Circuitry is provided for detecting an edge in a global framework clock (GFC) signal that is supplied to the transmitter domain. A common alignment signal is manufactured that is based at least in part upon the GFC signal. A multiplexer and register arrangement is operable to output the second clock signal in response to the common alignment signal which is also used for gating the data transfer operations clocked by the first clock signal.

摘要： A method of synchronising an Orthogonal Frequency Division Multiplexed (OFDM) IEEE 802.11a data packet at a receiver is disclosed. The 802.11a data packet has a series of short training sequence (STS) symbols as a preamble. Cross-correlation at the receiver of the STS in the 802.11a packet PLCP preamble with the modified reference STS, that is circular shifted by eight samples, results in a main correlation peak but with reduced pre- and post-lobes. To locate the cross-correlation peak, a running second derivative of the cross-correlation function is performed. Peak selection employs a running comparison of the position and magnitude of all peaks in the intermediate neighbourhood of the local peaks. Following selection of a peak from within the cross-correlation function of the first STS in the PLCP preamble, both the position and magnitude of the first STS is compared to those of the second STS. Based on the two independent calculations, the start of the OFDM frame is estimated.

摘要： Normally ordered robust VSB data are reordered in accordance with a first interleave to produce reordered robust VSB data. The reordered robust VSB data and ATSC data are reordered in accordance with a second interleave to produce normally ordered robust VSB data and reordered ATSC data. The normally ordered robust VSB data and reordered ATSC data are time multiplexed for transmission to a receiver. The receiver discards the reordered ATSC data or the normally ordered robust VSB data depending upon receiver type or user selection. A robust VSB receiver is able to process the normally ordered robust VSB data upstream of an outer decoder without an interleave thereby avoiding the delay associated with an interleave.

摘要： Power line communication (nullPLCnull) signals are transmitted between a head-end PLC transceiver coupled to multiple remote PLC transceivers over a electric power and communications distribution network in accordance with a timing controlled PLC data frame which determines how much bandwidth is allocated to downstream transmission from the head-end to the remotes and to upstream transmissions from one or more of the remotes to the head-end. The configuration of the timing controlled data frame can be dynamically modified to achieve higher bandwidth for the downstream traffic and to satisfy changing bandwidth needs of each remote.
