In order to enable appropriate reporting of information related to an event to be reported when the event occurs, a report processing apparatusincludes: an information obtaining unitconfigured to obtain first report information reported from a terminal apparatus with respect to a target event; a determination unitconfigured to determine one or more report destinations associated with the target event from a plurality of candidate report destinations (report destination apparatusto) based on the first report information; and a communication processing unitconfigured to transmit information related to the first report information to the one or more report destinations associated with the first report information.

Report processing apparatus, report processing method, program, and recording medium

Provided is a broadcast system that assigns a communication channel to a program and broadcasts data for the program to terminals, the broadcast system including a broadcast management device and a communication access network device. The management device calculates as a score a measure of viewing requests from users of the terminals for a plurality of programs, and determines a program to actually broadcast on the communication channel based on the score. The communication access network device transmits program data on a communication channel according to the determination of the broadcast management device.

Broadcast system, broadcast management device, broadcast method, and terminal

A terminal apparatus receives data of a program to be viewed selected from among broadcast programs, and notifies viewing information indicating the program to be viewed. A base station apparatus broadcasts the data of the program to a cell, mutually notifies the broadcast program between cells, acquires the viewing information from a terminal apparatus, and starts to broadcast the program in the destination cell when predicting that the terminal apparatus is moving into the cell where the program that is being viewed is not broadcast.

Wireless communication system, base station apparatus, terminal apparatus, and broadcast method

A recording apparatus is provided with a recording medium, an error correction circuit and an error processing circuit. The error correction circuit corrects errors in read data which are read from the recording medium. The error processing circuit inserts a data pattern in data which are output from the error correction circuit in a case where a missing error remains in the data. The data pattern indicates that the missing error remains.

Recording apparatus, recording system and error notification method

A first actuator for controlling positions of all of a plurality of heads within a wide area and a plurality of second actuators for individually controlling the heads within small areas are provided. When two or more of the heads are in write or read state, one or more of the heads, which are not in write or read state, is preliminarily move to a track position to be accessed next.

Data storage using disk media

A bus switch for realizing bus transaction across two or more buses comprises N (N: integer larger than 1) bus bridges, a switch module and a scheduler. When a transaction cell is generated by a bus bridge, the bus bridge adds a destination port number to the header of the transaction cell. The destination port number designates one of output ports of the switch module to which the transaction cell should be transferred. When the transaction cell is supplied to an input port of the switch module, an output port multiplexer of the switch module is controlled by the destination port number in the transaction cell, and the transaction cell is transferred to one of the output ports that corresponds to the destination port number, thereby the transaction cell is transferred to a destination bus bridge. By the addition of the destination port number, the scheduler does not have to directly control connection of a transfer path in the switch module. Therefore, the scheduler and the switch module do not have to be connected together via lines, and thus the scheduler and the switch module can be formed in separate and independent two LSIs. Consequently, the number of buses connected to the bus switch can be increased easier in comparison with conventional bus switches.

Bus switch for realizing bus transactions across two or more buses

The invention provides a server wherein a plurality of unit servers are arranged in parallel to each other to allow an increase in the number of clients and continuous data that can be transferred without interruption to clients using a comparatively small number of buffers. A video server includes unit servers including a file apparatus having video data stored discretely therein. When a preparation sign reporting section of a unit server reports a sign, a file read-out section of the unit server reads out the video data and stores them in a buffer, and in response to a sign of a distribution start sign reporting section, a distribution section starts distribution of the video data. A predetermined number of unit servers repeat reading out and distribution of discretely stored video data cyclically at timings set for them in this manner. Consequently, the buffers can be utilized effectively to effect distribution without interruption.
