  • Patent number: 6505347
    Abstract: A control information generating apparatus is provided which is used in broadcast systems designed to transmit audio and video signals and/or teletext signals together with video control information and program information in multiplexed form. The control information generating apparatus transmits EPG (Electronic Program Guide) information (i.e., control information) for transmission of the audio and video signals and includes a control information generating circuit and a control information outputting circuit. The control information generating circuit receives program schedule information on a program from a broadcast database to generate and output control information. The control information outputting circuit receives and output the control information to a multiplexer in which the control information and a data signal from an audio/video data transmitter are multiplexed and transmitted on a carrier wave.

  • Patent number: 6362783
    Abstract: A method of detecting a position of a radio mobile station in radiocommunications, which is capable of accurately and simply finding the position of the mobile station. At a measuring point the mobile station measures the reception radio strength levels from a plurality of base stations and conveys the measurement results through the base station to a control station. The control station learns, through a neural network, the correlation between the reception radio strength levels and the position of the mobile station on the basis of the measurement results at a plurality of measuring points and the positions of the measuring points. Subsequently, when the mobile station communicates to the control station the reception radio strength levels measured at an arbitrary point, the control station estimates the position of the mobile station, causing those measurement results, on the basis of the correlation obtained through the learning.
