An IEEE 1394 cable includes two individually shielded twisted data pairs of wires, carrying differential signals TPA and TPB, and two power conductors, carrying power signals VP and VG. The two twisted data pairs of wires are each individually shielded by a braided shield. The cable also includes an overall braided shield and a no smoke, no halogen, flame retardant jacket. Preferably, the cable has a length of 4.5 meters and includes 26 gauge wire for the two twisted data pairs. Longer, alternate embodiments of the cable incorporate heavier gauge wire for the two twisted data pairs. Preferably, the gauge wire used for the two power conductors is constant for the different lengths of cable. An active disconnect is used to provide an active repeater between IEEE 1394 cables. The active disconnect provides ports, into which cables are connected, and a physical connection including electronics necessary to form an active node on the IEEE 1394 serial bus. The active disconnect receives signals from one port and resynchronizes, encodes and transmits those signals out of the other ports. The active disconnect draws power from the power conductors of the IEEE 1394 cables which are coupled to it.
A powering arrangement for providing power to an Ethernet connected device, comprising a power unit connected via a first terminal to the device and via a second terminal to an Ethernet cable carrying two signal wire pairs and two spare wire pairs. A connection is provided within the power unit for interconnecting the signal wire pairs and a first one of the two spare wire pairs to the device, and a source of power is provided within the power unit connected to a second one of the spare wire pairs from the device for providing power thereto.
A network cable includes first and second connectors and corresponding sets of connector pins and signal wires. A coupling piece controls the routing between the first set of signal wires and the second set of signal wires. The coupling piece includes at least two configuration settings where each configuration setting actuates a corresponding routing between the two sets of signal wires. The first configuration setting may actuate a passthrough configuration where each first connector pin is connected to a like numbered second connector pin. The second configuration may actuate a crossover configuration in which at least some of the first connector pins are connected to like numbered second connector pins and at least some of the first connector pins are connected to un-like numbered second connector pins. The coupling piece may include a cylindrical outer piece that rotates around an inner piece to actuate the various configuration settings.
A passenger interface unit as provided that is positioned on a floor portion of an aircraft and attaches to a seat track on the aircraft floor portion. The passenger interface unit can be reattached to different locations long the seat track throughout the aircraft.
A multi-media system for transferring a single program transport stream and a method therefor are provided. A receiver is for receiving a transport stream. For the receiver to control recording and reproduction performed by a recording/reproducing device, the receiver selects one program to constitute a single program transport stream and transfers the single program transport stream to the recording/reproducing device. Here, a program number is transferred, by correcting program association table (PAT) information of the transport stream. Accordingly, the recording/reproducing device can recognize the program number within the single program transport stream to be recorded. Therefore, the receiver can perform remote control of the recording/reproducing device without the extra transfer of the program number. Also, the receiver provides an on-screen graphic (OSG) to the recording/reproducing device, resulting in an OSG of consistent appearance.
In the 1394 communication, communication at a data rate of S100, S200, S400, S800, S1600, S3200 or at a faster speed in the future can be performed. When the 1394 communication is performed with an optical-fiber cable and a UTP cable, it is possible to cope with high-speed communication by arranging bits being not used at a low speed, on a data stream. Transmission of data rates is realized by sending speed-control symbols at a predetermined speed. As for a Tp bias signal, an equivalent object is achieved by sending predetermined control symbols.
