20110200046 | COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND COMPUTER PROGRAM - Disclosed herein is a communication apparatus, including: a transmission policy holding section configured to hold transmission policies each corresponding to a conversation; and a transmitted frame control section configured to modify transmitted frames of the conversation in accordance with the corresponding transmission policy held by the transmission policy holding section. | 08-18-2011 |
20110292793 | COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND COMPUTER PROGRAM - A communication apparatus includes: a higher-layer processing unit that starts up a retransmission process of a corresponding packet in accordance with reception of a Duplicate ACK packet; and a lower-layer processing unit that collects a plurality of the Duplicate ACKs received through a network as one ACK and sends the one ACK to a higher layer. | 12-01-2011 |
20130215910 | TRANSMISSION APPARATUS, TRANSMISSION METHOD, PROGRAM, AND COMMUNICATION SYSTEM - A transmission apparatus transmits a timestamp in increments of 10 | 08-22-2013 |
20150030038 | SYNCHRONIZATION PROCESSING DEVICE, SYNCHRONIZATION PROCESSING METHOD, AND PROGRAM - The present technology relates to a synchronization processing device, a synchronization processing method, and a program, which make it possible to achieve frequency synchronization in a shorter period of time. A jitter amount calculation unit calculates a jitter amount on the basis of a synchronization packet containing time information. A jitter amount accumulation unit calculates a cumulative value of the jitter amount calculated by the jitter amount calculation unit. A comparison unit outputs a frequency error correction value from the calculated cumulative value of the jitter amount. A control voltage generation unit outputs a frequency control voltage based on the frequency error correction value. The present technology can be applied to a receiver device that is time-synchronized with a transmission device, for example. | 01-29-2015 |
