Abstract:
PROBLEM TO BE SOLVED: To more firmly prevent information tapping and altering. SOLUTION: A pseudo-random number computing circuit 42 generates pseudo- random numbers by giving a seed to prescribed functions. A pseudo-random number converting device 41 converts the generated pseudo-random numbers into a session key, that is used as a cryptographic key for a ciphering, while a random number information obtaining device 43 obtains two decimal places, that are made into an integer, of the temperature outputted by a temperature sensor 44 as a random number information which is externally provided and impossible to predict. The circuit 42 changes the seed with the timing, based on a certain one random number information and based on other one random number information.
Abstract:
PROBLEM TO BE SOLVED: To provide a data processing device capable of providing high satisfaction to a user with respect to entire quality of a plurality of sets of data processing when performing the plurality of sets of data processing with a limited processing capability. SOLUTION: A plurality of processing execution parts 33 perform the plurality of sets of data processing, each having a process amount corresponding to a specific process quality under different process qualities. A process quality determination part 32 determines priority among the plurality of sets of data processing based on characteristic data indicating characteristics of the plurality of the sets of data processing, and specifies the process quality of each of the plurality of the sets of data processing based on the determined priority.

Abstract:
PROBLEM TO BE SOLVED: To suppress wasteful power consumption without depending upon the capacity of a device such as an IC. SOLUTION: Regulator parts 14-1 and 14-3 step down the DC voltage being cleared of noise and rectified by a filter part 11 and rectified and smoothed with a forward converter 12, and output it respectively to one system each of a power output system 21 for the main board of an electronic apparatus, based on the control of PWM controllers 15-1 and 15-3. Regulator parts 14-2, 14-4, and 14-5 step down the inputted DC voltage and output it respectively to output controllers 16-1 to 16-3, based on the control of PWM controllers 15-2, 15-4, and 15-5. The output controllers 16-1 to 16-3 output the voltage supplied from the regulators 14-2, 14-4, and 14-5 to the two systems of the power output system 21, when ON control signals are supplied via a control input system 22 from the electronic apparatus.

Abstract:
PROBLEM TO BE SOLVED: To determine the validity of setting of a receiver, and to discriminate a part with erroneous setting. SOLUTION: When it is decided that a physical connection confirmation packet is received in S1, processing proceeds to S2 to perform the reception processing of the physical connection confirmation packet. When a service reception confirmation packet is determined to have been received, the processing proceeds to S4 to conduct the reception processing of the service reception confirmation packet. When it is judged that both of the physical connection- and service reception confirmation packets are received in S5, the processing proceeds to S6 to decide that the whole setting has correctly been performed. When only the reception processing of the physical connection packet is determined to have been performed in S7, the processing proceeds to S8 to judge the existence of an error in upper-order setting. When it is determined that no reception processing has been performed in S7, the processing proceeds to S9 to judge the existence of the error in the physical connection. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a recording device for simply recording/reading binary data even when some of nonessential items are omitted in describing metadata. SOLUTION: The recording device generating and encoding metadata comprises a metadata description part for describing the metadata, and an encoding part for encoding the metadata described in the metadata description part in a binary format and generating encoded data. The metadata description part describes alternative information for embedding alternative data to the encoded data when no data exists for a nonessential item in the metadata. The encoding part embeds the alternative data for encoding when the alternative information is described. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To handle a recording material in one recording unit (or reproducing unit) generated during the period from the start to the end of data recording. SOLUTION: A recording control part 14 of a built-in camera recording-and-reproducing apparatus includes an information acquiring part 32 to acquire a media profile necessary for reproducing the data in recording the data, a take generation part 34 to generate a plurality of clips successively generated beyond the limit as a single take during the time from the start to the end of the data recording to a removable media by determining whether the clips exceed the limit of the storage capacity of the file system of the removable media or not and generating successively the next clip when the limit is exceeded, and a media profile updating part 35 to update the media profile by recording the generated single take in the media profile.

Abstract:
PROBLEM TO BE SOLVED: To continuously reproduce the same content from certain equipment to another equipment through a user's simple operation. SOLUTION: When a portable terminal 40 is detected by a short-range communication method during interruption of content reproduction in an HDD recorder 10, the HDD recorder 10 transmits reproduction interruption information including content identification information of the interrupted content to be stored in the portable terminal 40. When the portable terminal 40 is detected by the short-range communication method in a network AV player 20a, the portable terminal 40 transmits the reproduction interruption information to the network AV player 20a to request reproduction of the corresponding content. The network AV player 20a requests, based on the received reproduction interruption information, provision of the corresponding content to the HDD recorder 10, whereby the interrupted content is continuously reproduced in the network AV player 20a.

Abstract:
PROBLEM TO BE SOLVED: To provide a distributed processing mediating system capable of efficiently processing large-scale computing by distributed processing on a network and maintaining secrecy between the distributed processing consignment terminal and a distributed processing capability offering terminal. SOLUTION: This distributed processing mediating system is provided with at least one distributed processing consignment terminal consigning distributed processing, at least one distributed processing capability providing terminal having excessive information processing capability, and a distributed processing mediating server carrying out a mediating service between them via the network. The distributed processing mediating server mediates the excessive processing capability offered by the distributed processing capability providing terminal to the distributed processing consignment terminal.
Abstract:
PROBLEM TO BE SOLVED: To effectively generate and manage operation mode information and PSI information. SOLUTION: At a display part, a GUI(graphical user interface) of a hierarchical structure consisting of the network information, transponder information, multiplexer information and input port information in the order of upper sides is displayed on a monitor. This GUI shows a transmission path of the program source of a digital satellite broadcast device and also shows a directory of various types of set information which are stored in a storage part.
