摘要： In optical communications between a base station and a local station, the wavelength of a laser light source for a signal, high LD, in the base station that generates downstream signal light is set to a wavelength with an effect of Raman amplifying an upstream light signal that propagates through an optical fiber 2. In the optical fiber 2, an upstream light signal transmitted from the local station to the base station is amplified with the downstream signal light from the laser light source for a signal, high LD, while the upstream light signal is propagating through the optical fiber 2.

摘要： In optical communication between a parent station and a child station, the wavelength of the signal laser light source high LD of the parent station generating the downstream signal light is a wavelength having the effect of Raman-amplifying the upstream optical signal propagating in an optical fiber (2). In the optical fiber (2), while the upstream optical signal transmitted from the child station to the parent station propagates in the optical fiber (2), the upstream optical signal is amplified by the downstream signal light of the signal laser light source high LD.

摘要： PROBLEM TO BE SOLVED: To automatically judge a power line communication apparatus directly under a gateway from among a plurality of power line communication apparatuses constituting a LAN. SOLUTION: Based on a fact that the data requesting response are transmitted from the network of PLC to the home gateway side, and the response data are transmitted from the home gateway side to the network of PLC, when one PLC modem directly under a home gateway 7 is set as a master unit and other PLC modems are set as slave units out of a plurality of PLC modems constituting a network of power line communication, a determination is made that a PLC modem A that receives the response data from a port for PLC is the master unit, and a PLC modem B that receives the response data from other port is a slave unit.

摘要： PROBLEM TO BE SOLVED: To provide a multicast communication system capable of appropriately multicasting a great capacity of data such as video system data even when using a MODEM with which a communication velocity of a PLC, radio LAN or the like fluctuates violently. SOLUTION: The present invention relates to a multicast communication system 1 which comprises a plurality of MODEMs 3, 8 capable of IP communication, wherein one MODEM 3 is capable of receiving from a high-order network an IP protocol compliant multicast packet 30. The one MODEM 3 converts the multicast packet 30 received from a side of the high-order network 6 into a unicast packet 31 and transmits it to the other MODEM 8 and the other MODEM 8 which receives the converted unicast packet 31, returns the converted unicast packet 31 to the original multicast packet 32 and transmits the multicast packet 32 to a terminal device 9 that requires the multicast packet 32.

摘要： PURPOSE: To simplify the constitution of a receiving side by transmitting a spread spectrum signal in each specific time unit while switching its radio propagation mode. CONSTITUTION: A spread spectrum signal (SS signal) prepared by a spreading modulator 3 is amplified by a transmitting amplifier 7. Then the amplified signal is transmitted from either one of base station side transmitting/receiving antennas At1 , At2 which are mutually separated by λ/4 (λ is wavelength) through a circulator CIR and an antenna switch 8. A controller 4 allows a hopping pattern generator 5 to generate a hopping pattern. In addition, the controller 4 controls the switch 8 so that the SS signal is given to the antenna At1 when the hopping pattern of a 1st chip is generated and the SS signal is given to the antenna At2 when the hopping pattern of a 2nd chip is generated.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive system configuration with which both processing and transfer of information are in low volume by enabling receipt confirmation to be performed without using slips. SOLUTION: An arbitrary first information is encrypted into a second information and recorded on a label 102 using a two-dimensional code 101. A third information decoded from the second information is sent to a receipt confirmation device 151 by a destination 140 of an article 100. Then the receipt confirmation device 151 determines if the third information sent from the destination 140 matches with the first information, and if so, the receipt of the article 100 by the destination 140 is confirmed.

摘要： PROBLEM TO BE SOLVED: To allow a CATV enterprise 13 to easily insert a new program to an MPEG 2 transport stream. SOLUTION: A broadcast satellite operating company 11 organizes a broadcast program in a way that a 2nd service stream together with a 1st service stream consisting of program packets is included in a transport stream. The CATV company 13 inserts a program to the transport stream by replacing the 2nd service with a service stream to be inserted. In this case, the CATV company 13 adds a packet identifier having been added to the 2nd service stream to the service stream to be inserted. Thus, man-hours to seek packet identifiers not in use and to re-generate additional information can considerably be reduced.

摘要： PURPOSE:To improve the precision of character recognition by more exactly calculating the degree of difference at the device for extracting the feature amount of a direction component from the direction component of the contour line or the center line of a character and recognizing the character by calculating the degree of difference between the feature amount and a standard feature amount decided in advance. CONSTITUTION:Conventionally, the degree of difference is calculated while assuming that the feature amount is regularly distributed. However, the feature amount to be really extracted is not regularly distributed but asymmetrically distributed. Then, a logarithm conversion part 7 converts the extracted feature amount to a logarithm and prepares a direction component logarithm vector. Then, a difference degree calculation part 8 calculates the degree of difference by comparing the prepared direction component logarithm vector with a standard pattern generated by a standard pattern generation part 9. Therefore, the degree of recognition for recognizing characters can be improved.
