摘要:
A communication terminal device includes a connection establishing unit which establishes a connection by a call control protocol with a destination device designated by an IP telephone number, a communication protocol requesting unit which request a presentation of a plurality of communication protocols which can be supported by the destination device over the connection, a communication protocol selecting unit which selects one communication protocol which the communication terminal device itself can support from the communication protocols presented from the destination device as a response to the request by the communication protocol requesting unit, and a communication unit which communicates with the destination device over the connection by the communication protocol selected by the communication protocol selecting unit.

A method and system for monitoring, controlling and diagnosing operation of a machine such as a business office machine including a facsimile machine, a copier, and a printer. When the speed of communication between the remote device and machine is not urgent, a connectionless mode of communication may be used. The form of connectionless communication is an electronic mail message transmitted over the Internet. However, when a condition needs urgent action, a direct connection is used for communication such as communication via a telephone or ISDN line. The information obtained from the machine is stored in one or more data bases within a company and information of the machine is shared between a service department, engineering and design department, manufacturing department, and marketing department. As communication over the Internet via electronic mail is not secure, the connectionless-mode messages transmitted using Internet electronic mail are encrypted.

Disclosed is an Internet FAX apparatus which, after receiving an Internet address from a certain destination, can communicate with the same destination in later transmission or during communication by connecting to a LAN and switching to an Internet FAX mode requiring no communication charge. An Internet facsimile apparatus on the receiving side transmits its Internet facsimile function and Internet address on an NSF signal in a standard protocol of G3 facsimile transmission and/or transmits its telephone number, Internet facsimile function, and Internet address on TSI and NSS signals in the standard protocol of G3 facsimile communication. The Internet facsimile apparatus registers an Internet facsimile function and Internet address of a partner apparatus as destination data. The Internet facsimile apparatus communicates with the partner apparatus by using the Internet address in the destination data in later transmission or by disconnecting ordinary facsimile mode communication and switching to the Internet FAX mode.
摘要:
A method for processing non-standard facilities frames by T.38 gateways, wherein the T.38 gateways includes at least one transmitting gateway and at least one receiving gateway, the transmitting gateway is connected with a transmitting facsimile machine, and the receiving gateway is connected with a receiving facsimile machine. The method includes: a) the transmitting gateway and the receiving gateway determining the types of all received V.21 frames; b) when the receiving gateway or the transmitting gateway receives a non-standard frame NSF, modifying the non-standard frame NSF, so that the corresponding receiving facsimile machine or transmitting facsimile machine is unable to receive a correct NSF frame; c) the receiving gateway encapsulating the modified NSF frame data, or the transmitting gateway modulating the modified NSF frame data and transmitting the modulated frame data. The method modifies the rate negotiation performed with proprietary frames as a negotiation performed with standard frames.
摘要:
The present invention discloses a method of displaying a sequence for sharing digital data items with a set of recipients using a terminal capable of using at least two communication modes for communicating with the recipients. The method comprises the steps of obtaining a first list of recipients communicating with the terminal according to a first communication mode, obtaining at least one second list of recipients communicating with the terminal according to a second communication mode, displaying on the mobile terminal a representation of each recipient in the lists thus obtained, selecting at least one representation, determining the communication mode to be used according to the representation selected and sending data item to the recipient whose representation was selected according to the determined communication mode. The invention also describes a sharing device adapted to implement the method, in particular a digital camera.
摘要:
A facsimile machine of the present invention includes a plurality of encryption processing units, which respectively encrypt transmission data by different encryption methods, an encryption processing determination unit, which transmits the transmission data to either one of the plurality of the encryption processing units, and a transmission unit, which transmits the encrypted transmission data. A facsimile communication method of the present invention applies either one of a plurality of encryption methods, encrypts data by the applied encryption method and transmits the encrypted data.
摘要:
In data transfer in isochronous mode using an IEEE1394 serial bus, the data transfer rate is guaranteed, but data transfer is disabled if the number of channels is insufficient. An already assigned channel is released by lowering the data transfer rate currently using that channel, and the released channel is assigned to new data transfer, thus allowing the new data transfer.

A document scanning device reads an image on a document while scanning the image, and generates image data based on the image. The document scanning device selects and sets a scanning speed in accordance with a transfer mode used when the document scanning device transfers the image data to another apparatus. The document scanning device controls the amount of generated image data by using the set scanning speed to successively read the image, whereby optimal transfer processing in accordance with the transfer mode can be performed. By switching a transfer path in accordance with the type of the read data, i.e., binary data per pixel or multilevel data per pixel, efficient data transfer can be performed.
