A communication device transmits to a relaying device a transmission right grant request for requesting a grant of a transmission right to a transmitting device, and the relaying device determines whether the received transmission right grant request is a command associated with the transmission right of the communication device or a command associated with the transmitting device, and if it determines that it is the command associated with the transmitting device, it grants the transmission right to the transmitting device, and starts broadcasting of data being transmitted from the transmitting device. In addition, when receiving from the communication device an operation command for operating the transmitting device, the relaying device determines a type of the command and transmits it to the transmitting device.

A communication promotion method is provided to appropriately support communication by a plurality of users in different environments. A character, operable by an IRC client, is linked to or installed in a user terminal. An administration devicedetects a specific event in a channel and sends a specific command to the IRC clientvia IRC. Commands do not always have to be sent to all of the IRC client, and may be different according to the IRC client. The user terminaldetects the aforesaid command and sends it to the character. Characters at each user terminaloperate as specified by the command.

A telephone set and an information terminal are connected by a packet switched network. The information terminal has a control target list in which a predetermined telephone set information is stored, and a terminal controller. The terminal controller generates, based on an instruction from a user, a control command in which an instruction related to multimedia phone communication is recorded, and sends that command to the predetermined telephone set. The predetermined telephone set has a terminal list storing information about the information terminal, and a telephone controller. The telephone controller generates, based on the control command received from the information terminal, a call control command for performing multimedia phone communication with another telephone set on the packet switched network, and sends that command to the other telephone set.

Telephone communication system and method for controlling the telephone communication system

A gateway apparatus connects a packet-switched network to a PSTN, the packet-switched network having a plurality of information terminals connected thereto. The gateway apparatus includes a recognition operation, an incoming call notification operation and a connection operation. The gateway operates (or is configured) to recognize information terminals on the packet-switched network. The incoming call notification operation notifies all the recognized information terminals of an incoming call upon reception of an incoming call from the PSTN. The connection operation connects the PSTN to an information terminal that has responded to the incoming call notification first. An incoming call notification may be sent to all or a plurality of the information terminals on the packet-switched network in a point-to-multipoint communication using a broadcast address or a multi-cast address. Source-identifying information and destination telephone numbers on the PSTN may be allotted to the information terminals in advance so that the destination of an incoming call notification can be specified. Additionally, a telephone message recorder terminal may be used to receive incoming calls when no other terminal responds to the incoming call.

A chat system in which conversations by characters in plural channels are displayed, and of these conversations, a conversation in a main channel and conversations in other channels are displayed in individual regions on a display screen, and an inputted statement is displayed in an intermediate region of the individual regions . The chat system hence realizes a display method having a notice function for use while working in an office, and information extracting function enabled by electronic expression of conversations, along with a recording medium used for execution thereof.

The present invention was made in order to provide a technology capable of safely ciphering compressed and encoded image data irrespective of lines or media and carrying out a correct decoding operation without any shifts in the frames of ciphered moving pictures. Further, so as to prevent giving any means of encoding from comparison of image ciphered data and so as to generate totally different ciphered image data from the same data compressed images, a processing is executed not on an ECB mode but on such modes as CBC, CFB, OFB or the like. Moreover, as an initial vector, information different for frames included in a header, that is, time information from the start of an image or a frame sequential number, is used. In this way, even if compressed images within adjacent frames are accidentally the same, totally different ciphered data can be obtained.

Encoder and decoder

A telephone call alerting system is applied to a telephone communication system accommodating a line to which a telephone terminal is connected, a plurality of telephone numbers being assigned to the line. The telephone call alerting system includes an output unit for outputting information indicating a telephone number of a call when the call is received by the telephone terminal, a plurality of informing units for outputting an alert indicating that a call has been received by the telephone terminal, each of the plurality of informing units corresponding to one of the plurality of telephone numbers, a memory unit for storing a table indicating a relationship between the plurality of telephone numbers and the plurality of informing units, an identification unit, when the call is received by the telephone terminal, for identifying one of the plurality of informing units corresponding to the telephone number indicated by the information output by the output means, with reference to the table, and a control unit, when the call is received by said telephone terminal, for supplying an instruction of outputting the alert to the one of the plurality of informing units identified by the identification means, so that the one of the plurality of informing units outputs the alert.

Moving-picture data in a frame is encoded without depending on another frame of moving-picture data, and moving-picture data in a frame is encoded depending on another frame of moving-picture data. Whether each frame of moving-picture data is a frame which was encoded without depending on another frame of moving-picture data or which was encoded depending on another frame of moving-picture data is determined. The frame of moving-picture data was thus determined as having been encoded without depending on another frame of moving-picture data. The enciphered moving-picture data includes the frame of moving-picture data and the frame of moving-picture data which was determined as being the frame which was encoded depending on another frame of moving-picture data.
