Abstract: To further correctly obtain related information about contents being received from a server. A communication apparatus 1 successively transmits request information that requests related information about contents being received via a network 30, at specified intervals (S1), receives related information corresponding to that request information (S2), temporarily stores (S3), displays it (S4), and performs contents updating processing. Here, if a direction to store the related information about the contents is entered, the communication apparatus 1 requests again request information for related information about contents, separately from the contents updating processing (S10). Then, the communication apparatus 1 receives related information corresponding to that request information (S11), and stores it (S13). This enables the latest related information to be further correctly obtained out of related information concerning contents, and obtaining related information before updating is reduced.

Abstract: An information provision apparatus previously stores associated information concerning an on-air program. The apparatus accepts a request for associated information from a client terminal CT which receives a program's broadcast signal. In synchronization with timing of accepting the request, the apparatus reads the associated information and transmits it to the client terminal CT. When the on-air program changes to a next program in such situation, the apparatus updates the associated information which should be read and transmitted. The apparatus can update the associated information to be transmitted in synchronization with program changeover. It is possible to provide the program in synchronization with the associated information without a time difference between both.

Abstract: The broadcast signal receiving means 2 receives the broadcast signal of the broadcast station 32a. While the broadcast signal reproduction means 3 reproduces the broadcast signal, the request information transmission means 4 transmits the request information for requesting the associated information of the broadcast station 32b which is different from the broadcast station 32a. The associated information receiving means 5 receives the associated information corresponding to the request information. The associated information display means 6 displays the associated information. Therefore, it is possible to browse the associated information of the broadcast station 32b when listening to the broadcast of the broadcast station 32a. This also means it is possible to acquire the associated information of the broadcast station 32b at the same time as its broadcast.

Abstract: In a group III nitride-type field effect transistor, the present invention reduces a leak current component by conduction of residual carriers in a buffer layer, and achieves improvement in a break-down voltage, and enhances a carrier confinement effect (carrier confinement) of a channel to improve pinch-off characteristics (to suppress a short channel effect). For example, when applying the present invention to a GaN-type field effect transistor, besides GaN of a channel layer, a composition-modulated (composition-gradient) AlGaN layer in which aluminum composition reduces toward a top gradually or stepwise is used as a buffer layer (hetero buffer).

Abstract: A setting information transmission means 1c transmits setting information (area information) concerning broadcast reception of a reproducing apparatus 1 itself and set by a user, to an external device. List information corresponding to the setting information and including broadcast station names, broadcast station identification information, and frequencies of broadcast stations which can be received by the reproducing apparatus 1 is returned to and received by a list information reception means 1d from the external device. The broadcast station names included in the received list information are displayed on the display means 1e. The user checks the displayed broadcast station names and makes an input operation. In response to this input operation, a recording means 1f records parts of the received list information (e.g., frequencies, broadcast station names, and broadcast station identification information) onto a recording medium, with the parts linked to each other.

Abstract: A client terminal CT transmits an acquisition request for musical composition information. An associated information provision server KS continuously receives the acquisition request at a given time interval. The associated information provision server KS transmits timing specification information along with the musical composition information corresponding to the acquisition request to the client terminal CT. The timing specification information specifies timing for the client terminal CT to transmit the acquisition request next. The associated information provision server KS controls a polling interval for acquisition requests. In this manner, acquisition requests can be distributed to those transmitted at a given time interval and those received in accordance with the timing specification information. A simple method can be used to prevent acquisition requests from being concentrated on the associated information provision server KS.

An information server 2 transmits a list of musical compositions broadcast in a designated time zone to a terminal unit 1, based on a retrieval key such as date and time zone from the terminal unit 1. The terminal unit 1 displays the received list of musical compositions on a display part 1a. At this time, the directive items for displaying the list of musical compositions broadcast before and after are displayed, together with the received list of musical compositions.

Abstract: Information items related to a plurality of musical pieces designated can be stored at a time. A storage means 1a can hold the information items related to contents. A receiving means 1b receives information items related to a plurality of contents broadcast. A temporary storage means 1c stores the information items 4 related to the contents, for some time. An instructing means 1d instructs that the related information items stored in the temporary storage means 1c be recorded in the storage means 1a. When instructed by the instructing means 1d, the recording means 1e records the related information items 5a stored in the temporary storage means 1c, as one set 5, in the storage means 1a. At the same time, the recording means 1e records in the storage means 1a the name of this set, in association with the set 5. The related information items can therefore be recorded in accordance with a single instruction.

Abstract: A large number of pieces of recorded information are made to be discriminated and identified easily any time after they are recorded. When broadcast information is received from a broadcasting station 32a, contents-related information relating and corresponding to the contents of the broadcast information is received by a reception means by way of a network 30 and temporarily stored in a temporary memory means 3. When there is an external request for recording the related information, the related information temporarily stored in the temporary memory means 3 is recorded in a keeping means 4 by a related information recording means 5 and, at the same time, the broadcast information that is being received at the time of receiving the recording request is correlated with the related information recorded in the keeping means 4 and recorded in the keeping means 4 by a broadcast information recording means 6.

Abstract: An information-processing apparatus 1 renders it easy for a user of a terminal apparatus 2 to review the information about the contents broadcast by broadcast stations other than the broadcast station from which the apparatus 2 is receiving signals. In the apparatus 1, a broadcast-station information storing means 14 stores the broadcast-station information in association with the area where the apparatus 2 can receive signals from the station, and a user-set information storing means 13 stores the user-set information about the terminal apparatus 2. A detecting means 12 detects broadcast stations from which the broadcast terminal apparatus 2 can receive signals, and generates, form the user-set information, list information that contains the names and identification data items of the stations detected. A transmitting/receiving means 11 transmits the list information to the broadcast terminal apparatus 2. The apparatus 2 displays a list of broadcast stations, which is represented by the list information.
