摘要： PROBLEM TO BE SOLVED: To change a frequency dividing ratio of a clock signal without enlarging a circuit scale. SOLUTION: Whenever a reference clock signal is inputted from a reference clock signal source 20, output signals of stages Q2 and Q3 of a counter changing output states of respective stages and data on frequency dividing ratio setting of two bits are inputted to a clock selector 28b. The clock selector 28b generates a first or second pulse signal having a period which is n-times and m-times as much as a prescribed period longer than the output signal of a constant level and the reference clock signal in one output terminal in accordance with a value of frequency dividing ratio data. An output signal from an output terminal of the clock selector 28b, the reference clock signal and a third pulse signal having a period which is L-times as much as the prescribed period are inputted to a T-type flip flop 32b. When the output signal of the constant level is supplied, the T-type flip flop 32b frequency-divides the third pulse signal by the prescribed frequency-dividing ratio in accordance with the reference clock signal. When the first or second pulse signal is supplied, it frequency-divides the first or second pulse signal in accordance with the reference clock signal. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To increase the number of participants in a conference without improving the capability of existing servers.
SOLUTION: Servers are divided hierarchically into an upper layer server 2c and lower layer servers 2a, 2b, wherein the server 2a supplies sound signals from terminals 4a through 4d and the server 2b supplies sound signals from terminals 4e through 4g while mixing to the upper layer server 2c. The upper layer server 2c supplies a lower layer mixing sound signal from the lower layer server 2a as an upper layer mixing sound signal to the lower layer server 2b, and supplies a lower layer mixing sound signal from the lower layer server 2b as an upper layer mixing sound signal to the virtual server 2b. The server 2a supplies the mixing signal of an upper layer mixing sound signal from the upper layer server 2c and sound signals from the terminals 4a through 4d excepting its own terminal to the terminals 4a through 4d. It is also true for the server 2b.

摘要： PROBLEM TO BE SOLVED: To transmit/receive a sound signal by a plurality of transmitting/receiving apparatus connected with a network without using a server. SOLUTION: Three or more transmitting/receiving apparatuses 2 communicable with the sound signal are connected with a network 4. Each of the transmitting/receiving apparatuses 2 has a database 44 with information indicating which of other transmitting/receiving apparatus should perform communication of the sound signal with the transmitting/receiving apparatuses 2 stored therein. A determining part 42 determines other transmitting/receiving apparatuses at communication destinations, based on the information stored in the database 44. A control unit 40 communicates with the transmitting/receiving apparatuses 2 at the destinations, according to the determination result of the determining part 42. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent overflow and underflow of a reception buffer, in digital data communication which uses a streaming reproduction system. SOLUTION: A transmitter samples a hundred packets P1 to P100 between a time T1 and a T2 with a transmission-side sampling frequency fs. A packet transmission interval between the packet P1 and the last packet P100 is ΔTs=T1 -T2 . A receiver operates with a reception-side sampling frequency fr and a packet reception interval of the packets P1 to P100 is set ΔTr=T4 -T3 . The difference between the packet transmission interval ΔTs and a packet reception interval ΔTr at the packets P1 and P100 is detected, and the reception- side sampling frequency fr is corrected, so as to reduce this difference.

摘要： PROBLEM TO BE SOLVED: To allow a master set side to send power to each slave device as drive power for each slave device in the system of master /slave configuration. SOLUTION: Two transmission lines 21, 22 connect to a master device 1 and pluralities of slave devices 3, 3,... are bus-connected to the transmission lines 21, 22. Isochronous real time data are sent/received among the device 1 and the devices 3, 3,... via the transmission line 21, and control data are sent/received via the other transmission line 22. Moreover, a power superimposing device 4 superimposes a DC voltage Vs used for drive power for the slave devices 3, 3,... between the transmission lines 21, 22. Thus, the two transmission lines 21, 22 are used to send the real time data, the control data and the DC voltage Vs.
