Abstract: There are provided a device for displaying link information and a method for displaying the same which display the image of an actual object superimposed with the label of link information so as to easily obtain information on the actual object and to display a moving link. An image input part obtains the image signal of an actual object. A link information receiving part receives link information transmitted by a transmitter. A link contents detection part detects the link contents. An attribute information detection part detects the attribute. A link position detection part detects the link position. The image signal obtained by a synthesizing part is superimposed with the link contents in the display coordinate of a link label calculated by a coordinate conversion part in accordance with the attribute information. A display part displays the image signal synthesized. The user uses a pointing device to easily obtain the link information on the actual object in accordance with the link label.

Abstract: A network system includes a plurality of communication nodes. In the network system, data transmitted from a server apparatus (1) is received by a PC (2) and a PDA (3). Each of relay nodes 4 obtains a communication network parameter concerning the communication network connecting the communication nodes with each other. Each of the relay nodes (4) also determines a communication route, based on a format conversion parameter concerning format of data transmitted from the server apparatus (1) and types of format conversion at format converters (5a) and (5b), and the obtained communication network parameter.

Abstract: If an instruction is provided so as to receive second content information in place of first content information on the basis of only one operation by a user while the first content information is received through a connection formed in a communication network, the connection for communication of the first content information is disconnected, and thereafter, a connection for communication of the second content information is formed. In this manner, network resources can be reserved or released without consciousness of users.

Abstract: While transmitting real-time data through a network 30, a data-transmitting apparatus 10 receives the data representing a data-loss rate, from a data-receiving apparatus 20. In the data-transmitting apparatus 10, the rate control section 15 compares the data-loss rate with the preset first and second threshold values. When the data-loss rate is lower than both the first threshold value and the second threshold value, the rate control section increases the transfer rate at which the data-transmitting means transmits the real-time data. When the data-loss rate is higher than the first threshold value and lower than the second threshold value, the rate control section does not change the transfer rate. When the data-loss rate is higher than both the first threshold value and the second threshold value, the rate control section decreases the transfer rate.
