A contents additional services inquiry server for receiving inquiries for additional services provided by a contents center and a third-party contents additional services providing server, wherein a registration request specifies a contents identifier uniquely identifying contents, and requests registration of registration request information including each additional service information regarding service that can be provided with respect to the contents having the contents identifier and provider location information regarding a location of a respective provider of each additional service. Registration request information registered by the contents center and registration request information registered by the third-party contents additional service providing server are separately stored. The registration request information specified by the contents identifier is searched and returned when there is a request for the additional service, where registration request information registered by the contents center and registration request information registered by the third-party contents additional service providing server are separately presented.

Contents additional service inquiry server for identifying servers providing additional services and distinguishing between servers

Content data and metadata are obtained and reproduced, and combination interface information defining information necessary for executing combination operation on the contents is generated. The combination operation on the contents is controlled by following combination data definition based on the combination interface information and, as necessary, by using external input information entered from an external unit. The combination feedback information for controlling the reproduction operation of the contents and metadata is generated, and the reproduction operation on the contents is controlled based on the combination feedback information.

Content combination reproducer, content combination reproduction method, program executing the method, and recording medium recording therein the program

A hardware/software co-verification method that achieves fast simulation execution by implementing a C-based native code simulation without degrading the accuracy of timing verification. This method is a method for co-verifying hardware and software, by using a host CPU, for a semiconductor device on which at least one target CPU and one OS are mounted wherein, first, a timed software component described in a C-based language or constructed from binary code native to the host CPU and a hardware component described in the C-based language are input as verification models, necessary compiling is performed, and the compiled components are linked together. Next, a testbench is input and compiled. Then, the components and the testbench are linked together, after which simulation is performed and the result of the simulation is output.

A load balancing method and apparatus are provided, by which loads in a wide range of the entire system can be balanced with a small overhead with respect to load balancing processing, and the mean response time of the entire system can be shortened. The method has the steps of (i) estimating a load of the present node based on the number of tasks being or waiting to be processed and determining an estimated load value of the node; (ii) accepting a task passing through a logical ring network, and every time a task is accepted, comparing the estimated load value and a threshold value which is set with respect to the number of tasks existing in the node so as to limit the load of the node; and (iii) judging, based on a result of the comparison, whether the accepted task is handed over to a task processing unit, or is transmitted to the logical ring network again without handing over the task to the task processing unit. The threshold value may be changed in accordance with a change of the number of tasks passing through the logical ring network during a fixed period, or when a round trip task is detected.

Non-uniform system load balance method and apparatus for updating

A semiconductor device comprising a low-heat-resistance heat discharging route suitable for small semiconductor devices, such as an IC card, is disclosed. Heat arising from electronic parts is efficiently dispersed to the outside, thereby accomplishing a decrease in size and a heightening of function. In a specific embodiment, a CPU is mounted on a substrate in a position of thermal via holes. A high-heat-conducting material such as semifluid silicone rubber is placed between a CPU mounting face of the substrate and lower panel located on the opposite side of the substrate. The high-heat-conducting material is a filler having the ability to change shape and the property of electrical nonconductivity. A greater part of the heat arising from the CPU is transmitted through the thermal via holes from the CPU mounting face of the substrate to the opposite side, and further to the high-heat-conducting material which conveys the heat to the lower panel. The heat is dispersed from the lower panel surface directly into the atmosphere.
