Abstract: Control commands are sent from communication stations (A, B) to devices (D to F), such as a VTR, connected to a communication station (C) via radio networks (NW) provided between the communication stations (A, B) and the communication station (C), thereby controlling the devices (D to F). As a result, video signals outputted from the devices (D to F) via analog wirings (W) are sent from the communication station (C) to the communication stations (A, B) so that videos based on the video signals are displayed in display devices (A11, B11) via the communication stations (A, B). In the communication station (C), identifiers for specifying controllers (A1, B1) which have sent the control commands to the communication stations (A, B) and identifiers for specifying the devices (D to F) controlled are made to respectively correspond to each other, and are stored so that a controller which can be allowed to control is specified.

Abstract: A breathable decorative layer is laminated onto a multilayer fiber composite, i.e., a breathable material, constituted from many layers of fibers. Between the breathable decorative layer and the breathable material, a substantially unbreathable film or a breathable sheet or film having through holes is interposed. Thus, a decorative multilayer material having high acoustic absorbing capability, processability, lightweightness, rigidity, heat resistance, thermal formability, recyclability, and designability can be provided at low cost. By laminating this decorative multilayer material on a laminated closed-cell foam material, a laminate for interior materials having acoustic absorbing capability can be provided at low cost despite the use of the laminated closed-cell foam material.

Abstract: When the operator pushes a switching button provided on a controller, a local communication station selects a remote communication station in accordance with a predetermined order, and in the remote communication station, a device is selected in accordance with a predetermined order. When the operator pushes the switching button provided on the controller again, a message that switching to all devices in the remote communication station has been completed is transmitted to the local communication station, and in accordance with the foregoing order, a remote communication station, which is a remote communication station to be selected next, is selected. In the remote communication station concerned, a device is selected in the same manner in accordance with a predetermined order. With this arrangement, it is possible to easily select a desired content even if contents such as devices are located at a plurality of stations in a dispersed manner.

Abstract: An electric appliance 1 has a code correspondence data table that accommodates the correspondence among the control signals of the remote control units belonging to recording medium drive apparatuses 2-1 to 2-m and signal reception apparatuses 3-1 to 3-n and a code correspondence data table that accommodates the correspondence between those control signals and the various operations performed by the electric appliance 1 to select contents. With reference to these code correspondence data tables, contents are selected and reproduced according to control signals transmitted from any remote control unit 6.

Abstract: When a transmission station having a voluntary transmission right transmits FINALL FRAME as a TXOP ending frame to HC, the HC transmits an acknowledgement frame ACK after SIFS following the reception of FINAL FRAME. Here, when the transmitting station has detected that no frame transmission is performed over the communication network from any other ESTAs in PIFS after the transmission of FINAL FRAME, FINAL FRAME is retransmitted in DIFS after the transmission of FINAL FRAME. By performing such a communication management, it is possible to accurately manage a voluntary transmission right even when the communication medium has a low reliability in a network in which one network pathway is time-shared by a plurality of communication apparatuses.

Abstract: In a display device, when an application operating section is to communicate, each communication state detecting section detects a communication state of each radio communication section. A physical layer selecting section then determines if each physical layer is capable of providing an effective throughput required by each application operating section by each radio communications section. Furthermore, the physical layer selecting section selects from the physical layers a physical layer available for communications of each application operating section.

Abstract: To achieve communication, an AV data reception apparatus transmits an ID with which it permits itself to be identified to an AV data transmission apparatus. On receiving this ID, the AV data transmission apparatus identifies, based on the ID, the functions compatible with the AV data reception apparatus, and changes the functions of its own communication operation blocks according to those identified functions.

Abstract: Between two nodes, data in the form of two different signals are transmitted bidirectionally, in accordance with IEEE1394 through one optical fiber cable. At the time of data transmission, data of two different signals is converted to data of one type of signal at one node, and transmitted to the optical fiber cable, and at the other node, the data received from the optical fiber cable is converted to the original data of two different signals, and transmitted to a subsequent processing circuit in accordance with IEEE1394. At this time, in a transmission sequence for requesting and granting priority of transmission over the optical fiber cable between both nodes, the priority of transmission is granted alternately to both nodes.
