Patent ID: 7492707

Claim:
A transmitting device for transmitting data to at least one of a plurality of receiving devices by means of wireless signals via a channel shared by the plurality of receiving devices, comprising: a receiving part which receives reception quality data for the respective receiving devices that is periodically transmitted from each of said plurality of receiving devices; a storage part which stores one or a plurality of sets of past reception quality data for said respective receiving devices; a prediction processing part which determines future predicted values relating to the reception quality of the respective receiving devices at the time of data transmission via said channel on the basis of the one or plurality of sets of past reception quality data for the respective receiving devices stored in said storage part and current image quality data for the respective receiving devices received by said receiving part; and an assignment processing part which selects receiving devices and assigns transmission data to be transmitted to said selected receiving devices to said channel on the basis of the future predicted values for the respective receiving devices at the time of data transmission determined by said prediction processing part, wherein said prediction processing part determines the reception quality data for the respective receiving devices at the time of said data transmission on the basis of said one or plurality of sets of past reception quality data for the respective receiving devices and said current reception quality data for the respective receiving devices, and determines, as said future predicted values for the respective receiving devices, multiplication results obtained by respectively multiplying the substitution results obtained by respectively substituting the reception quality data for the respective receiving devices at the time of said data transmission into a specified increasing function, and said current reception quality data for the respective receiving devices.
