摘要:
A data path control device with a first interface section for connecting to a LAN, second interface section for connecting to an external network through a small transmission capacity two-way line such as a telephone line, and third interface section for receiving a large capacity data from a large transmission capacity one-way line such as a satellite broadcast line. The data path control device changes the sender address of the data transmitted from a computer to a network based on a previously set correspondent relationship, thereby controls the path so that the large capacity data from the network is transmitted through the large transmission capacity one-way line. A path of the reply data from a network responsive to the request data from a computer outputted to an external network is selected by the computer side, and in the case that the reply data is composed of large capacity data, a satellite line having a large transmission capacity can be selected.

Data receiving device and method in which data is received through a broadcast network, the data is reconstructed into packets usable on a computer, and the packets are output to the computer, directly or through a local area network. The reconstructed packets are preferably in the format of Internet Protocol (IP) packets. A destination address allocated to the data receiving device on the broadcast network is converted, via the data receiving device, to an IP address allocated to a personal computer on the Internet.

To allow bi-directional communication by using a bridge type feed and to reduce a load on equipment such as a receiver connected to a UDL network, a communication apparatus for carrying out communication on the Internet using an uni-directional communication line comprises an interface (5b) for receiving IP datagram to be transmitted to the communication line at the side for transmitting data to the communication line, and an interface (12) for realizing a virtual communication route from the receiving side to the transmitting side on the communication line, for carrying out bi-directional communication as UDLR. Moreover, the apparatus determines a destination of a packet inputted to the feed through predetermined interface, then determines which network the packet should be transferred to in accordance with the determined destination of the packet, and then transfers the packet through a predetermined interface only when transfer is necessary.
摘要:
A path control packet is sent from a router to a receiver. The receiver capsulates the received packet and transmits a capsulated IP packet to a feed via a ground line. The feed extracts the path control packet by decapsulation and transmits the packet to a router. At the same time, path control information is sent to a satellite line. The router processes the packet as if the path control information from the router reached via the satellite line. When a receiver receives a packet via the satellite line, it transmits the packet as a packet to a router. This router processes the packet as if the path control information from the router reached via the satellite line.

A disclosed antenna device includes a plate-like ground plate, and a feeding unit that extends from the ground plate for a predetermined length at a predetermined angle. The feeding unit is constituted by a half-body, which is a body, such as a circular cone, halved by a plane perpendicular to the ground plate, and the feeding unit is prepared perpendicular to the ground plate.
