  • Patent number: 7689163
    Abstract: Via a mobile communication network, a transmission apparatus receives position information representing a current position of a reception apparatus. Based on the received position information, the transmission apparatus generates notice data indicating that it is necessary to correct preprogrammed program information identifying a program which has been preprogrammed for viewing or preprogrammed for recording and being generated at the reception apparatus, and transmits the generated notice data to the reception apparatus. Accordingly, a transmission apparatus is provided which generates information that allows preprogramming of a broadcast program for viewing or recording to be properly performed at the reception apparatus side, or which generates a correct broadcast program table, and transmits the generated information or program table to the reception apparatus.

  • Patent number: RE40241
    Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the siganl points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into low and high frequency band components which are designated as first and second data streams respectively.
