This application discloses systems and methods for receiving information associated with a first set of processing instructions and presenting a second icon indicating a change in status of data associated with the first set of processing instructions. A user selection of one of a first icon or the second icon may then be received. The selection of the first icon may cause execution of the first set of processing instructions, whereas selection of the second icon may cause execution of a second set of processing instructions.

Information processing apparatus, display method, and display program

There is provided an information processing apparatus including: a display panel for displaying a plurality of objects; an area region detection unit for detecting an operation body positioned on the display panel, and detecting an area region of the display panel corresponding to the operation body; a contacting object detection unit for detecting one or a plurality of objects contacting the area region detected by the area region detection unit; and an object selection unit for setting part of or all of the objects detected by the contacting object detection unit to a selected state.

Information processing apparatus and information processing method

Disclosed herein is a data transmission system permitting secure and more reliable transmission of data from a data transmitter to a data receiver or receivers. The system comprises: a data transmitter for encrypting data and transmitting the encrypted data; data receivers for receiving the encrypted data from the data transmitter; satellite links used for data transmission from the data transmitter to the data receivers; and bidirectional communication channels which are also used for transmitting data from the data receivers to the data transmitter and which have a smaller capacity of data transmission than the satellite links. The satellite links are used to transmit encrypted data from the data transmitter to the data receivers. At least the bidirectional communication channels are used to communicate restrictive data transmission control information between the data transmitter and the data receivers.

Data transmission controlling method and data transmission system

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.

Communicating method, transmitting apparatus, and receiving apparatus

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 () for receiving IP datagram to be transmitted to the communication line at the side for transmitting data to the communication line, and an interface () 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 a 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.

Communication method and communication apparatus

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.

Communication path control device, communication path control method, and communication path control unit

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.
