    摘要: A new-part acquiring unit acquires a part of a block generated by a block generating unit, as a new part to be contained in a packet. A retransmission-part acquiring unit acquires a part of a block corresponding to a NAK as a retransmission part to be contained in a packet among blocks held in a retransmission buffer unit. An encoding unit groups a new part acquired by the new-part acquiring unit and a retransmission part acquired by the retransmission-part acquiring unit, and generates a packet. A modulating unit modulates a packet output from the encoding unit. A wireless processing unit performs a predetermined wireless transmission process to a modulated packet, and transmits a processed modulated packet via an antenna.

    摘要: In a device equipped with an audio output, a range of the audio output level in regular use is set. When an attempt is made to change the setting to a volume level exceeding the range of the audio output level having been set, a request is made for an acknowledgement that the operation is appropriate, and only if a reply is received within a given time, is the volume setting changed. Such a method prevents the audio output from a television set or audio equipment to be increased to a volume level higher than necessary due to an operating error in a volume setting operation.

    摘要: An available bandwidth measurement system and method. The available bandwidth of a network path is determined by determining round-trip times of packets utilizing varying bandwidth to a receiving node. An increase in packet round-trip time indicates congestion of a link in the path. In some embodiments, the bandwidth range measured is expanded or decreased to locate a congestion point or to provide greater precision in determining available bandwidth.

    摘要: A system and method of load balancing a network having a plurality of client systems and servers. The load balancing system and method distributes requests from the client systems to different servers on a wide area network by selecting the most optimal server for a specific client request. The client request for a server is received from a client system and the destination point of the client request is resolved in part by a load balancing server selector. The client request is sent to a load balancing server based on the resolved destination point and one server out of a subset of the plurality of servers is selected based on a predetermined criteria, such as network traffic congestion or server load, and a conduit to the client system and the selected server for transmission of the client request is provided.

    摘要: A speech coding apparatus which selects an optimum code from a code book, the optimum code giving the minimum magnitude of error signal between the input signal and the reproduced signal obtained by a filter calculation using a linear prediction parameter from a linear predictive analysis unit with respect to the codes of the code book, wherein the code book is formed by thinning to 1/M (M being an integer of two or more) the plurality of sampling values constituting the codes. To compensate for the deterioration of the quality of the reproduced signal caused by thinning the sampling values in this way, an additional linear predictive analysis unit is further introduced and use made of an amended linear prediction parameter instead of the linear prediction parameter from the originally provided linear predictive analysis unit.
