Abstract: Information processing with flexibility in interpretation of a standard is disclosed. In one example, an output unit adds additional information related to the BB packet to output the BB packet to a baseband (BB) packet after an error correction decoding process. The additional information includes at least one of a delimiter, a precision time protocol (PTP), or BB packet information. The BB packet information includes at least one of information indicating whether or not reception of the BB packet is stable, information indicating whether or not there is an error in the BB packet, a packet length of the BB packet, a relative physical layer pipe (PLP) ID of the BB packet, or an absolute PLPID of the BB packet.

Abstract: A signal processing device includes an acquisition unit that acquires identification information associated with data obtained by decoding a reception signal that includes a signal included in a first layer and a signal included in a different layer and superimposed on the signal of the first layer in a power axis direction, the data being output to a post-stage processing unit, a decoding unit that decodes the signal of the different layer on the basis of a result of decoding of the signal of the first layer after the decoding of the signal of the first layer, and an output control unit that outputs data obtained by decoding the signal of the different layer to the post-stage processing unit without outputting data obtained by decoding the signal of the first layer to the post-stage processing unit, in a case where data identified by the identification information is data obtained by decoding the signal of the different layer.

Abstract: There is provided a decoding circuit including; a first decoding unit that decodes a first signal from a multiplexed signal in which the first signal and a second signal are multiplexed in an LDM (Layered Division Multiplexing) system; and a second decoding unit that decodes the second signal from the multiplexed signal using the decoding result of the decoded first signal, wherein the second signal is selectively decoded based on noise information related to a reception state of the multiplexed signal.

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: Channel bonding is realized in a receiving apparatus that receives terrestrial digital broadcasting compliant with an ATSC 3.0 Standard. A receiving section selects any one of a plurality of frequency channels as a bonding source channel and receives a frame from the bonding source channel. A control section performs processing for obtaining one frequency channel in which packets are to be bonded with the bonding source channel among the plurality of frequency channel as a bonding destination channel on the basis of the frame and processing for controlling the receiving section to newly receive a frame from the bonding destination channel. A decoding section decodes the frame and acquires the packets. A bonding section bonds together the packets corresponding to the bonding source channel and the packets corresponding to the bonding destination channel.

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: Disclosed herein is a decoding device including: an extracting section, a storing section, an allocating section, and a decoding section. The extracting section acquires data containing plural code words and information other than the plural code words in one frame, and extracts the plural code words from the data every one code word. The storing section at least stores the one code word extracted by the extracting section. The allocating section sets time obtained by dividing time for the one frame by the number of code words contained in the one frame as time allocated to decoding of one code word. The decoding section decodes the code word within the time allocated by the allocating section.

The projector and camera can be mounted on a vehicle such that the camera is at the predetermined angular position in relation to the light projector. A detecting device on the vehicle for detecting vehicular travel over a fixed distance can serve to operate the projector and the camera synchronously.
