  • Publication number: 20160079998
    Abstract: A code bit of an LDPC code in which a code length is 16200 bits and an encoding rate is 7/15 is interchanged with a symbol bit of a symbol corresponding to any of 8 signal points defined by 8PSK. In the interchanging, when 3 bits of code bits stored in three units of storages having a storage capacity of 16200/3 bits and read bit by bit from the units of storages are allocated to one symbol, a (#i+1)-th bit from a most significant bit of the 3 bits of code bits is set to a bit b#i, a (#i+1)-th bit from a most significant bit of 3 bits of symbol bits of the one symbol is set to a bit y#i, and a bit b0, a bit b1, and a bit b2 are interchanged with a bit y1, a bit y0, and a bit y2.

  • Publication number: 20150264426
    Abstract: Plural streams are synthesized into one stream, and preferable transmission and reception of the synthesized stream to and from an external device is realized. Transport stream packets of plural transport streams are synthesized to create a synthesized stream, and the created synthesized stream is transmitted to an external device. In this transmission, a count information adding area provided in each of the transport stream packets is brought into a state to which a particular count value is added for each of the transport stream packets of the synthesized stream. This configuration notifies the external device that a function for handling packet order switching based on count information is not provided, and receives from the external device a synthesized stream containing the respective transport stream packets arranged in the same order as the order of the transport stream packets at the time of transmission.

  • Patent number: 9088173
    Abstract: A control apparatus 13 outputs an order signal to order supply apparatuses 12-1 through 12-N to perform supply of a signal in a contactless manner at a respectively different timing. The control apparatus 13 determines that a moving apparatus 11 is stopped at the position of the supply apparatus 12 being the output destination of the signal output order, when a wireless signal is received from the moving apparatus 11 within a certain period of time after outputting the order signal. Then, the supply apparatus 12 at the position at which the moving apparatus 11 is ordered to start supplying a signal.

  • Publication number: 20150022263
    Abstract: The present technique relates to a demodulation device, a demodulation method and a program capable of realizing a demodulation process at a rate equivalent to a case where I and Q channel signals are not inverted, even when the I and Q channel signals are inverted. A frequency correction unit establishes synchronization of a frequency and clock based on a signal from a frequency synchronization unit. A channel inversion detection unit of a frame synchronization unit detects presence or absence of inversion of I and Q channel signals, and supplies, as a detection result, a channel inversion detection result to the channel inversion control unit. The channel inversion control unit switches the I and Q channel signals if the inversion has occurred, based on the channel inversion detection result. This technique can be applied to a demodulation device.
