Abstract: When image communication is conducted by using one of a plurality of different image communication systems via a sending/receiving path including an IP network (101), a transmitter (105) and receivers (108, 108a, 112, 115) or devices (gateway (111, 113) or an IP network interface (109)) for relaying the image communication existing in the sending/receiving path store SDP media stream descriptions, which include different image communication systems usable by the transmitter and receivers, in an SIP message and send the SIP message, and select an image communication system for use in practical image communication in given order of priority and image communication control parameters to be used in the appropriate image communication system, on the basis of the SDP media stream descriptions.

Abstract: There is disclosed a communication apparatus designed to assure the execution of ring type multi-address data transmission. In order to ensure that a user see a received image, transfer to a next station is not carried out until the received image is printed out. With the passage of specified time after the reception of the image, transfer is executed to the next station.

Abstract: An image communication apparatus converts image data received through a communication line into bit image data to be reproduced as a visible image by means of using a data converting unit and a reproducing unit. The apparatus converts data from a data processing apparatus into bit image data to be reproduced as a visible image by means of using the data converting unit and the reproducing unit, so as to accomplish an efficient system as a whole.

Abstract: The present invention relates to a facsimile apparatus for providing a single/dual side mixture mode capable of transmitting and receiving original images including single/dual side mixture efficiently. Under control of a CPU 22, information indicating presence/absence of back side image information corresponding to transmission/reception image information is informed together with page number and image front/back information, by a post message signal transmitted from a transmitter to a receiver. If the image information read from a back side of an original is substantially entire-white, the transmitter omits transmission of back side image information having the entire-white. In this case, by informing information indicating absence of back side image information corresponding to front side image information from the transmitter to the receiver by the post message signal, single/dual side mixture image informations can be transmitted and received.

Abstract: A communication apparatus receives the identification information of a partner station, and performs a communication operation in accordance with the received identification information. A first detecting unit detects a calling signal. An identification information receiving unit detects the identification information of a calling party upon detection of the calling signal, and a second detecting unit detects whether or not the terminal of the calling party is a data communication terminal. A registration unit registers the identification information of the partner station in a memory, so that whether the partner station is a speech or data communication terminal can be discriminated later. A control unit checks if the identification information receiving unit receives the identification information of the calling party.

Abstract: A communication system in which when an incoming call has arrived, a communication line having the capability of a high sampling rate is automatically selected without assistance of an exchange operator by transmitting an ultra high speed modem indication signal indicating the capability of data communication at an ultra high speed modem rate among the capabilities of a called terminal, and receiving an ultra high speed modem capability signal indicating the capability of an ultra high speed modem of a calling terminal.

Abstract: A facsimile communication system and a communication apparatus reduce a loss time due to the synchronization of transmission/reception and shorten a communication time. They also shorten a communication time in a full duplex communication mode and allow proper switching of the full duplex communication at the transmission/reception replacement. DIS-CFR signals, EOP-DCN signals, NSS-TSI signals and TSI-DCS signals of a facsimile communication protocol are connected by synchronization signals so that the synchronization signals are sent even after the sending of the protocol signal. Thus, the sending of the synchronization signal for one second when the next protocol signal is sent is not necessary and a time required for the protocol signal is shortened.

Abstract: An object of the present invention is to effectively utilize functions of a communication apparatus which can be connected to a communication network providing a call line identification presentation service. In order to achieve this object, setting as to whether or not call line identification presentation is to be performed to a communication destination is switched according to a communication mode at a time of call generation, and a call is actually generated based on the switched and thus selected setting, thereby improving operability in the switching as to whether or not the call line identification presentation is to be performed.

Abstract: There is provided an image receiving apparatus such as a facsimile apparatus which can record and output the received image data on a page unit basis. The apparatus comprises: a receiving unit to receive image data; a recorder to record the received image data; a generator to generate reception ID information including a reception number and a page number; and a controller for allowing the reception ID information to be added and recorded to the received image data every page. The recording mode is manually or automatically set into either a mode to cut and output the received image on a page unit basis or a mode to cut and output the received image on a communication unit basis.

Abstract: A facsimile apparatus has an AC power source and a standby power source which are selectively changed. The number of times of changing the power sources is minimized to limit deterioration of the AC power source. When the frequency of use of the facsimile apparatus is high, the AC power source is maintained in the on state.
