Abstract: The present technology relates to an information processing device, an information processing method, and a program that enable appropriate extraction of an ALP packet from a packet of a second packet included in a first packet regardless of a difference in interpretation of a standard. A payload length obtained on the basis of data of a header of a second packet included in a first packet is corrected.

Abstract: A reception apparatus that decodes a preamble reduces the size of a buffer that holds a decoding result. A holding unit holds a plurality of bits to each of which physical layer pipe identification information is assigned as a physical layer pipe presence/absence bit string. A reception unit receives a predetermined number of physical layer pipes that do not exceed the number of bits of the physical layer pipe presence/absence bit string and the physical layer pipe identification information of each of the predetermined number of physical layer pipes. A setting unit sets the value of the bit corresponding to the received physical layer pipe identification information of the physical layer pipe presence/absence bit string to one of two values, and sets the value of a non-corresponding bit to another of the two values. A decoding processing unit performs processing for decoding the physical layer pipe corresponding to the bit of the one value.

Abstract: The present technology relates to a signal processing device that enables TLV transmission, a signal processing method, and a program. The signal processing device includes: a demodulation processing unit that performs a demodulation process; a processing unit that performs a demux process; and a data signal line, a clock signal line, a sync signal line, and a valid signal line that are provided between the demodulation processing unit and the processing unit. A variable-length packet is transmitted between the demodulation processing unit and the processing unit through the data signal line, the clock signal line, the sync signal line, and the valid signal line. The variable-length packet is an Internet Protocol (IP) packet. The present technology can be applied to receivers that receive and process TLV streams.

Abstract: The present technology relates to a reception device, a receiving method, and a program capable of improving a reception state. A delay wave by multipath is estimated on the basis of sensor information detected by a sensor unit, a replica of the delay wave is generated by a sum of products of a coefficient for each delay wave and a signal of a reception wave according to delay time on the basis of the estimated delay wave by the multipath, and the generated replica of the delay wave is subtracted from the signal of the reception wave, thereby removing the delay wave from the signal of the reception wave. The present technology may be applied to a receiver which receives a broadcast wave.

Abstract: The present technology relates to a signal processing device, a signal processing method, and a program that enable transmission of time information in TLVs. The signal processing device includes: a demodulation processing unit that performs a demodulation process; and a processing unit that performs a demux process. In the signal processing device, time information included in a variable-length packet is transmitted from the demodulation processing unit to the processing unit at regular intervals. The variable-length packet is a Type Length Value (TLV) packet. The time information is Network Time Protocol (NTP) included in the TLV packet. The time information is placed at a predetermined position in a TLV stream including the TLV packet. The present technology can be applied to receivers that receive and process TLV streams.
