摘要： A musical tune playback apparatus is basically constituted by a controller (CPU), a digital media drive (e.g., a CD drive), a hard disk drive, and a sound system. Musical tune data recorded on a digital storage media (e.g., CD) are played back and are transferred to the hard disk drive together with relative information and/or image data. When a user inputs retrieval conditions, the controller retrieves musical tune data related to relative information (or image), which substantially matches retrieval conditions. Specifically, a relative information retrieval database is stored in a data area of the hard disk drive, wherein an auto-input area automatically describes an index ID, TOC information, and history information while a manual-input area describes other data and information with regard to each musical tune that is played back. Thus, desired musical tune data are automatically retrieved from the hard disk drive with reference to the database.

摘要： A wireless base station and a wireless mobile station repeat, via a wireless communication section therebetween, transmission of contents data from a server to a terminal. Each of the wireless base station and the wireless mobile station periodically transmits camouflage data to each of the server and the terminal, respectively, when the wireless communication section is incommunicative. This causes each of the server and the terminal to determine that a connection for data communication between the server and the terminal is continuing. Processing for the transmission/reception in the data communication is thereby prevented from being interrupted even when a wireless communication environment deteriorates and the wireless communication section becomes incommunicative.

摘要： In a communication system, a content server reads required data from a content database and transmits the data by packet communications over public communication lines, and a network management server receives and stores the required information from the public communication lines. The network management server sends the temporarily stored data to plural transmitter stations. Each transmitter station has a corresponding dividing device. Each dividing device receives and relays to the linked transmitter station only the amount of data required for transmission to the linked transmitter station. The remaining data is simply passed by the dividing device to the next dividing device without processing the data in any way.

摘要： A packet signal, formed according to an orthogonal frequency division multiplexing (OFDM) format, received by a receiver is decoded in a decoder device of the receiver. The packet signal includes a data code and a control code having a formula for decoding the data code. The control code is first decoded and analyzed to obtain the decoding formula contained therein. The data code is decoded during a period in which the control code is being analyzed, based on plural decoding formulae one of which coincides with the decoding formula contained in the control code. Data signals decoded based on the respective decoding formulae are sent to an output selector together with the decoding formula obtained from the control code. The output selector selects a data signal which is decoded based on a decoding formula that coincides with the decoding formula obtained from the control code.

摘要： In a radio communication system, a base station sends each of n send packets to a terminal station in parallel through n channels as they are in packet unit instead of dividing each of n send packets to send the same to the terminal station. It is possible in the base station to eliminate the need for a processing of dividing send packets and processing of resending divided send packets. It is also possible in the terminal station to eliminate the need of a configuration for receiving the divided send packets.
