Title: Burst signal receiver and receiving method in optical communication system
Inventor: UMEDA DAISUKE
IPC: H04B10/40
Filed: 2004-06-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a burst signal receiver capable of accurately discriminating a signal block and a non-signal block and outputting a signal with excellent S/N in an optical communication system wherein a master station and a plurality of slave stations are connected by optical fibers via a passive optical branching unit.  <P>SOLUTION: The burst signal receiver changes a reference value e to a high level on the basis of a point of time t1 when an output c of a discrimination circuit reaches a signal presence state from a signal absence state and changes the reference value e to a low level on the basis of a point of time when the output c of the discrimination circuit reaches the signal absence state from the signal presence state. When an intensity b of the burst signal rises, since the receiver is operated on the basis of the reference value at the "lower level", the receiver can quickly detect the rising of the burst signal b. When the intensity b of the burst signal falls, since the receiver is operated on the basis of the reference value e at the "higher level", the receiver can quickly detect the trailing of the burst signal b. Thus, the receiver can accurately discriminate the signal block when the burst signal b is received and the non-signal block when no burst signal b is received.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To make it possible to speedily recognize it when a device connected to a network is separated from the network while the device can not transmit a message denoting the separation from the network.  <P>SOLUTION: A digital television receiver 302 connected to the network registers the connection of a camcorder 300 to the network on the basis of a notice transmitted from the camcorder 300 communicatably connected via the network onto the network. This registration is updated on the basis of a notice transmitted from the camcorder 300 onto the network at a first time interval (an interval of a valid period). The digital television receiver 302 sets a second time interval shorter than the first time interval to a first timer so as to discriminate whether or not the television receiver 302 receives a prescribed notice (ssdp: alive) from the camcorder 300 at a time interval shorter than the second time interval. When the first time expires, the connection state of the camcorder 300 is confirmed by a search request.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
