An IFAX has a call controller that transmits and receives a SIP message to and from a destination apparatus via a SIP server, a file transmitter/receiver that transmits and receives image data to and from a Web server, and a communication manager that exchanges information for managing the image data transfer to and from the destination apparatus, by adding predetermined information to the SIP message. Thereby, the IFAX transfers the image data via the Web server while performing SIP-based communication with the destination apparatus.

IP communication apparatus, IP communication system, and data transmission method thereof

An IP communication apparatus has a file transferer that transfers a media data file to a destination apparatus, when determining that the destination apparatus has the file transfer function, based on transmission and reception of SIP messages to and from a call controller, which transmits and receives SIP messages to and from the destination apparatus via a call connection server. Thereby, the IP communication apparatus allows an easy transfer of the media data file.

Communication apparatus and data transmission method thereof

According to the data amount stored in a jitter buffer, which temporarily stores obtained data from a received voice packet, an operation timing of an output process of the jitter buffer and a data process of a codec and a modem is adjusted, the codec and the modem processing data that is sequentially output from the jitter buffer.

Data communication apparatus and data communication method

A data communication apparatus is provided with a VoIP processor and a modem that interchangeably executes a standard communication mode and a high-speed communication mode, the standard communication mode exchanging the voice packet at a predetermined transfer rate, the high-speed communication mode exchanging the voice packet at a rate faster than the rate of the standard communication mode. When capability information of an opposing apparatus is obtained, in accordance with a predetermined communication protocol, and it is detected that the opposing apparatus has the high-speed communication mode, the high-speed communication mode is selected for execution.

A dustproof structure for an electronic equipment includes internal switches disposed in a housing forming an external frame of the electronic equipment and an opening for use in operating the internal switches. The dustproof structure further includes a shutter plate for opening or closing the opening; and a cover plate for supporting the shutter plate, the shutter plate being freely slidable between the cover plate and the housing. A slide recess serving as a sliding area of the shutter plate is formed in the housing or the cover plate.

Dustproof structure for an electronic equipment

A data communication apparatus includes a communication section that performs pre-communication protocol to exchange a communication function with a communication destination terminal, and transmits data to the communication destination terminal after the pre-communication protocol. A detector detects whether or not the communication destination terminal can perform a short protocol in which at least a communication protocol for line probing is omitted. When the detector detects that the communication destination terminal can perform the short protocol, a controller obtains communication parameters from the communication destination terminal, stores the obtained communication parameters in a memory in association with the communication destination terminal. The stored communication parameters are utilized to perform the short protocol.

Data communication apparatus

To provide a system for processing program information in which the display structure of a program table can be freely changed in accordance with a requirement of or the taste of an audience, the system for processing program information is structured to include program information storage meansfor storing program information, and program table display meansfor two-dimensionally displaying a program table employing as the two axes, two attributesandselected from among all of the attributes that have been given to each piece of program information, to make the program table. For the audience, program tables of various constructions can be displayed on the display means at will and in respective program retrieval operations, a program table that is easy to use to search for a program can be obtained. An specific desired program can be found in a short time by selecting key word(s) related to each program and extracting them from the program or the like. This is useful for an audience member to make a plan of desired broadcasts for himself.

System for processing program information

A MODEM can shorten the processing time of an interface disposed between a data terminal equipment (DTE) and the MODEM. The MODEM stores an object program of a procedure in a memory and switches an operational mode of the MODEM automatically corresponding to the prescribed procedure thereby executing the procedure corresponding to the current operational mode. The MODEM further comprises a timer which monitors the transits time between a completed procedure and the next procedure, and the MODEM starts the process of a specified operational mode based on a mode-setting-instruction of the procedure as well as monitoring the transitions time by using the timer, and executing a next specified operational mode when the timer times out, thereby allowing the MODEM to perform the various operational mode switches.

Modulator and demodulator (MODEM)

A data communication apparatus includes a communication section that performs a pre-communication protocol and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When data corresponding to a destination terminal data is stored in the memory, a controller performs the pre-communication protocol with the destination terminal, using the stored communication parameters corresponding to the destination terminal. When a communication error occurs in a communication with a particular destination terminal having data stored in the memory, a memory controller deletes communication parameters corresponding to the particular destination terminal from the memory.

A data communication apparatus includes a communication section that performs a pre-communication protocol with a destination terminal and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When destination terminal data is stored in the memory, a controller reads the communication parameters corresponding to the destination terminal from the memory, performs the pre-communication protocol with the destination terminal, using the read communication parameters, and omits at least a communication protocol for line probing. When destination terminal data is not stored in said memory, the controller performs the pre-communication protocol with the destination terminal, using communication parameters acquired from the destination terminal under the pre-communication protocol without omitting the communication protocol for line probing.

An agent presentation apparatus for transmitting and receiving a message and operating based on a knowledge base and a rule base. In particular, where an agent for carrying out a user request uses knowledge of a knowledge description or an action description between agents and executes communication, for example. An agent can request a WWW page locally or remotely over a network to retrieve already existing contents and make a presentation that might include one or more of images, voice, and text along with the WWW page. The apparatus can also respond to user questions about the WWW page using the knowledge description and/or the action description, for example.
