An apparatus for displaying information received from a communication apparatus including a key information producing unit configured to produce key information used to authenticate the communication apparatus; a key information distributing unit configured to distribute the key information; an authentication information receiving unit configured to receive authentication information; an authenticating unit configured to authenticate the communication apparatus by verifying whether or not the authentication information was formed based upon the key information; and a display information receiving unit configured to receive display information from the authenticated communication apparatus, wherein the authenticated communication apparatus has a distribution range during reception of the key information such that the outputted key information can be acquired.

System and apparatus for information display

An apparatus includes a program guidance information holding section which holds electronic program guidance information, an algorithm holding section which holds separation point forming algorithms corresponding to a plurality of program attributes acquired from the electronic program guidance information, a program attribute determining section which determines one of the program attributes to which a to-be-processed program of the composite signal belongs based on the electronic program guidance information, an algorithm determining section which determines a separation point formation algorithm corresponding to the determined program attribute, and a separation point setting processing section which forms a separation point of the composite signal based on the determined algorithm.

It is determined whether or not the total length or ratio of periods in which an audio signal is set in a first mode with respect to the preset length of recorded program video signals is not larger than the preset length or ratio. When the total length or ratio is not larger than the preset length or ratio, the audio mode of the main body portion of the recorded video signal is determined to be the second mode. When it is determined that the audio mode is not the second mode, the audio mode of the main body portion is determined to be the first mode. Then, an adaptive processing section (algorithm) which forms separation information in a desired period of the video signal is set according to the above determination result and the thus formed separation information is stored.

A video recording/reproducing apparatus comprises a receiver which receives a broadcast program, an acquiring unit which acquires program information of the broadcast program, a recording unit which records the broadcast program received by the receiver together with the program information acquired by the acquiring unit, a selector which selects a type of the program, and a searching unit which searches a latest program of the type selected by the selector based on the program information acquired by the acquiring unit and the program information recorded by the recording unit.

Video recording/reproducing apparatus and method based on program information

An apparatus for displaying information received from a communication apparatus includes: a key information producing unit configured to produce key information for authenticating the communication apparatus; a key information display unit for displaying the key information; an authentication information receiving unit for receiving authentication information; an authenticating unit for authenticating the communication apparatus by verifying whether or not the authentication information was formed based upon the key information; and a display information receiving unit for displaying information from the authenticated communication apparatus.

A communication device to be used in an ad hoc network environment for enabling the user to utilize an application easily with a desired partner. After a communicable communication device was discovered, a service information provided by the communication device is acquired to display only the selected communication devices in accordance with the service information. The user selects the communication partner and causes the communication device to execute a predetermined application.

Communication device and method therefor

A communication equipment automatically interchanges business card information and displays such information on a display, thus making operation by a user for interchanging business card information unnecessary. The communication equipment includes a business card memory, a business card information display, a business card information reception function, a business card information transmission function, a communication equipment detection function, a network transmission/reception function, a storage device, a display and a mouse. When the communication equipment function detection function finds communicable equipment, the communication equipment displays a list of the communicable equipment. The user then starts communication with the desired counterpart. The business card information is automatically interchanged allowing direct input of the business card information to the equipment.

Communication equipment and method for business card information interchange

A communication network construction method comprises the steps of grouping the communication devices belonging to a communication network into one or a plurality of communication groups. In a selection step, one or a plurality of representative devices are selected in each communication group formed in the grouping step. In a communication step, each communication device communicates directly with the communication devices belonging to the same group, and communicates with the communication devices belonging to a different group by first transmitting data to the representative device of the same communication group and then causing the representative device to transfer a part or the whole of the data to the representative device of the different communication group.

Network construction method and communication system for communicating between different groups via representative device of each group

A server collects network administration information of terminals connected to the self-segment, assembles the collected network administration information into packets, and transfers the packets to other segments. The server stores the relationship, as a table, between the low-level layer address of each terminal connected to a corresponding segment and the corresponding high-level layer address on the basis of the collected network administration information and the network administration information included in packets transferred from other segments, and performs packet transfer between terminals through the segments by looking up this table.
