摘要:
An information processing apparatus, such as might be associated with an in-home audio or video control device or a home appliance operated by a user, is provided with input allowing the user to set accuracy of a log of device operation history and/or to set a ratio of disclosure of the log information. A log accumulation control device efficiently collects the log information and offers users diversified levels of accuracy for the log information. In a further configuration, user-designated information acquired form user operation of the device identifies frequency of viewing and listening to each program, and reproduction of contents is controlled as a function of the user-designated information, e.g. to select among common contents and contents of different classification types.

A power supply section includes a capacity detector capable of detecting the remaining capacity in a battery and a controller issuing power consumption reduction instructions to independently operable function devices based on usage priorities thereof. This allows power consumption operations to be performed such as stopping function devices with low priorities first based on the remaining battery capacity. As a result, power to function devices with higher priorities can be maintained. Based on the remaining battery capacity, the controller controls the operations of the function devices and uses a display to show information allowing the operator to identify operable and inoperable function devices as the battery capacity drops.

Communication using IPv6 is carried out, and conversion is given to a prefix of an IPv6 address in a firewall. A security channel for mutual authentication with an out-of-home apparatus or the like is carried out by the firewall, and only identification of an in-home apparatus is carried out on an in-home network by the firewall. A PC is connected to a PC in-home network different from the in-home network, and communication between the PC and the in-home apparatus is always carried out via the firewall.

An information processing system is configured such that which when an application handling multimedia, especially, moving images is performed by an information processor such as a personal computer, a sufficient processing performance is realized with the conventional CPU and bus capabilities. The information processing system includes a bus adaptor or bus converter for connecting a CPU bus and a system bus. The bus converter includes an operation processing unit (ALU) capable of performing a portion of an operating function performed by the conventional CPU or a portion of an operating function performed by an image processing board connected to the system bus, whereby the bus converter takes over a portion of a processing to be performed by the CPU or I/O module. Thereby, an overhead time for data transfer through the buses is reduced so that the total performance of the system is improved. Also, since a processing unqualified for the CPU, for example, a bit operation can be performed by a dedicated hardware, the information processing performance is improved.

An integrated information processing apparatus is provided with a display device and a generally transparent input tablet having an input surface placed on a display surface of the display device for outputting a pointing coordinate which is a coordinate on the input surface pointed by a user's finger or an indicator. The apparatus includes a circuit for determining an indication direction extended point coordinate from the pointing coordinate output by the input tablet and a predetermined value, and a display processing section for displaying a point on the display surface of the display device corresponding to the determined indication direction extended point coordinate so that it is distinguishably displayed on the display device.
摘要:
An object of the present invention is to provide network devices and a network device control method which enable control network devices connected to an IP network, AV devices connected over 1394IF through gateway devices from the IP network, and home devices connected to ECHONET to be controlled without distinction among them. To achieve this object, a network device to serve as a controller comprises a controller application that detects a service of a target network device, using a message complying with an information exchange protocol common to the network, collects information such as an access method for the service, a function name, and parameters, and controls the network device upon request, and an information exchange protocol processing part that exchanges messages according to a protocol common to the network devices. The network device targeted for control comprises service that provides information for the controlling network device to perform control to the controller, and the information exchange protocol processing part.
摘要:
An authentication information and a verification information are previously generated and the authentication information is stored to an authentication data generating apparatus, while the verification information is stored to a gateway. When a controller tries to make communication With a customer premises apparatus, the authentication data generating apparatus connected to the controller generates an authentication data using the authentication information and the gateway verifies the authentication data using the verification information. Moreover, the gateway restricts, when connected to the authentication data generating apparatus, the communication between the controller located in the outside of customer premises and the customer premises apparatus. Moreover, the gateway changes, while connected to the authentication data generating apparatus, an address of the customer premises apparatus and stores the changed address to the authentication data generating apparatus. The address of the customer premises apparatus is not informed to the controller provided in the outside of customer premises. Consequently, a system for safely controlling the customer premises apparatus from the outside of customer premises with the controller without bringing this controller into the customer premises to register a controller identification information to the gateway can be provided.

摘要:
An information processing apparatus can save an electric power when it is not in use and can be made active immediately after an operation medium such as a pen and a finger or the user approaches or comes in contact with the apparatus, the arrangement being such that a housing portion of the apparatus includes therein a sensor for detecting the approach or contact of a user operation medium or user and a state display unit for informing the user that the apparatus is in the active state or in the standby state, a power saving control unit controls a controlled object concerning a power consumption in response to the approach, contact or separation of the operation medium or user, and a timer included in the electric power saving control unit determines whether or not the operation medium or user is separate from the apparatus.
摘要:
Information terminal and information sharing method are provided which consider survival time of contents at a transmission destination and propagate the contents widely so as to be suitable for contents sharing. In the information terminal and information sharing method, contents allotted with survival time is received, the survival time allotted to the contents is changed, contents allotted with the changed survival time is transmitted to a different information terminal, and the contents is deleted after the changed survival time has expired.
