摘要： The diversity receiving apparatus of the present invention can arbitrarily determine the master branch which is the reference to synchronize the output timing among the symbols of the signals received by a plurality of branches depending on the receiving condition. This structure allows the master branch to be replaced with another branch in excellent receiving condition when the master branch gets into bad receiving condition or when the antenna signal wire on the master side comes off or breaks, thereby achieving the selection and synthesis of carriers.

摘要： A receiving device receives by multiple antennas a signal carrier-modulated with digital multivalued modulation, compares the distance between received signal points with a threshold preliminarily stored, to select complex signals to be synthesized when demodulating, and adjusts a ratio for synthesizing to correct likelihood for error correction. With such a makeup, a receiving device is provided that is resistant to a noise signal to ensure a favorable reception state.

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.
