Abstract:
A book data service system in which the book data can be delivered by the broadcasting such that the book data can be delivered to any user located at any place promptly and economically, without causing the waste of the resources. A book data service system if formed by at least one data center including: a data center computer for storing and managing book data; and a broadcasting facility for broadcasting the book data stored and managed by the data center computer according to a prescribed communication protocol using a synchronization control and an error correction scheme suitable for data delivery by broadcasting without confirmation from a receiving side; and a plurality of user terminals, each user terminal including: a receiver for receiving the book data broadcasted from the broadcasting facility of the data center; a user terminal computer for storing and managing the book data received by the receiver; and a display for displaying the book data stored and managed by the user terminal computer.
Abstract:
When encryption processing means is decided in encryption print communication which is made between a PC and a printer, a transmission/reception control unit of a printer receives information of encryption processing means from the PC and stores into a list storing unit of a RAM. A list of encryption processing means which are used in the printer is read out from a flash memory. An upper apparatus encryption processing means list is compared with the encryption processing means list. If the coincident encryption processing means exists, it is decided that this means is used for communication and the PC is notified of it. Since the PC transmits the print data encrypted by the notified encryption processing means to the control unit, the printing is executed on the basis of the decrypted print data.
Abstract:
The present invention relates to a method for displaying hierarchical structures. The method of the present invention can display graphically hierarchical structures of nodes from the nodes that are branch points, relay points or end points corresponding to apparatuses or functions and the connection relationships between the nodes. The display method of the present invention has the steps of arranging the nodes of the same layer subordinate to the same node on the same ellipse, arranging the subordinate ellipse of the same layer concentrically on an ellipse larger than the ellipse of the upper layer, and displaying the arranged hierarchical structure of nodes.
Abstract:
An image reader and an external terminal are connected to each other through a network. The image reader includes a reading unit, a reception section, a data conversion section, a transmission data generation section and a transmission section. The reading unit reads an image. The reception section receives terminal information from the external terminal. The data conversion section converts image data read by the reading unit into a predetermined data format based on the terminal information. The transmission data generation section adds additional information, which relates to processing of the converted image data, to the converted image data to generate transmission data. The transmission section transmits the transmission data to the external terminal.
Abstract:
A relay communication device capable of simplifying a method for designating a destination of relay transmission requesting mail to another relay communication device. A CPU reads Subject information stored in a data memory, analyzes the subject information, compares it with an identifying character for relay stored in a relay identification character storing section and judges whether or not a character matching any one of the identifying characters for relay exists in the subject information. If a matched character exists, E-mail is judged to be a relay transmission request. Then, password information is extracted from the subject information and the extracted information is compared with a password being stored in advance in the password information storing section. If the password exists in the subject information and if the existing password matches a password stored in a password storing section, the relay transmission request is implemented.
