Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method capable of ensuring good communication quality in data transmission using an LDPC code. The LDPC coding is performed on the basis of the parity check matrix of the LDPC code with the code length N of 1224 or 1152 bits and the coding rate r of 144/1224 or 144/1152. The parity check matrix includes an A matrix of M1 rows and K columns represented by a predetermined value M1 and an information length K=N×r of the LDPC code, a B matrix of a staircase structure of M1 rows and M1 columns, a Z matrix which is a zero matrix of M1 rows and N−K−M1 columns, a C matrix of N−K−M1 rows and K+M1 columns, and a D matrix which is an identity matrix of N−K−M1 rows and N−K−M1 columns. The A matrix and the C matrix are represented by a parity check matrix initial value table, and the parity check matrix initial value table is a table representing the positions of the elements of 1 of the A matrix and the C matrix for every 36 columns, and is a predetermined table. The present technology can be applied to, for example, data transmission using an LDPC code.

Abstract: Provided is an information processing apparatus that performs processing of sensor information using artificial intelligence. The information processing apparatus includes: a collection unit that collects first sensor information detected by a first sensor and second sensor information detected by a second sensor; a model generation unit that generates a learned model for estimating second sensor information corresponding to first sensor information on the basis of the first sensor information and the second sensor information that have been collected; an accumulation unit that accumulates the learned model; and a providing unit that provides a result of a service based on the learned model. The providing unit provides the learned model to the second apparatus in response to a request from the second apparatus.
