    Abstract: An information processing device (200, 300) includes a first encoding processing unit (212b), a second encoding processing unit (212d), and a communication unit (21, 41). The first encoding processing unit (212b) performs first error correction encoding processing in which a plurality of bit sequences are output from one or more bit sequences. The second encoding processing unit (212d) performs second error correction encoding processing in which one bit sequence is output from one bit sequence. The communication unit (21, 41) transmits at least one of a first transmission signal or a second transmission signal depending on a predetermined condition, the first transmission signal being obtained by performing the first error correction encoding processing and the second error correction encoding processing on transmission data sequences, and the second transmission signal being obtained by performing the second error correction encoding processing on the transmission data sequences.

    Abstract: An information processing device (200, 300) includes an encoding processing unit (212b) and a determination unit (231). The encoding processing unit (212b) performs error correction encoding processing in which a plurality of bit sequences are output from one or more bit sequences. The determination unit (231) divides the plurality of bit sequences into a first bit sequence group (BS1) and a second bit sequence group (BS2), and determines to transmit the first bit sequence group (BS1) and the second bit sequence group (BS2) through different propagation paths, the first bit sequence group (BS1) being decodable without performing error correction decoding processing corresponding to the error correction encoding processing, and the second bit sequence group (BS2) being used for the error correction decoding processing.

    Abstract: To realize an apparatus and a method for receiving a recognition level of an own vehicle from another vehicle and/or an infrastructure facility and performing control to improve a recognition level. A recognition level of the own vehicle calculated by another vehicle or the infrastructure facility is received, and control for improvement of a recognition level of the own vehicle is executed in accordance with the received recognition level. As the control for improvement of a recognition level of the own vehicle, any process is executed among: (a) a process of reducing a traveling speed or stopping; (b) a process of turning on a light; and (c) a process of changing transmission information from the own vehicle. As the process of changing transmission information, a process of adding, to the transmission information, vehicle location information, vehicle speed information, vehicle size information, or reference marker position information is executed.
