    Abstract: Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality.

    Abstract: A digital broadcast system is disclosed that real-time transmits additional information broadcast data specialized for area and time information to receivers located in a prescribed area via a gap filler. The digital broadcast system includes a satellite control station, a gap filler, and a receiver. The satellite control station assigns additional area ID codes to individual area-specialized additional information broadcast data, and transmits the area-specialized additional information broadcast assigned the additional area ID codes over a prescribed broadcast channel. The gap filler receives broadcast data, and determines whether the area ID code is contained in the received broadcast data. If it is determined that the determined area ID code is equal to desired area-specialized additional information broadcast data, the gap filler amplifies the output level of the received broadcast data, and transmits the amplified broadcast data to a shadow area. The receiver receives the re-transmitted broadcast data, and displays the area-specialized additional information broadcast data.

    Abstract: A tuner varies a reception frequency to receive each channel. A transport stream (TS) separation section, and a system control section separates network information table (NIT) information from the TS of each channel. A memory stores network identification (N_id) information which is included in the NIT and which can be identified for each residential area. The residential area to which most (N_id) information belongs is specified from a plurality of pieces of (N_id) information stored in the memory, and it is assumed that a receiver is installed in the area.

    Abstract: A method and apparatus are provided for determining a particular transmitting station from which program signals are received and translated by a monitored receiver within a test area and including mobile receivers. A stored transmitter characteristic table includes a corresponding transmitting station identification stored with a predefined subarea of a plurality of predefined subareas within the test area for each predetermined tuned frequency of the monitored receiver. A tuned frequency of the monitored receiver is identified and the particular transmitting station corresponding to the identified tuned frequency is identified responsive to both the identified tuned frequency of the monitored receiver and the stored transmitter characteristic table. The identified transmitting station data is stored with time of occurrence data.
