The present technique relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that can ensure favorable communication quality in data transmission using an LDPC code. LDPC coding is performed based on a check matrix of an LDPC code with a code length N of 69120 bits and a code rate r of 5/16, 6/16, 7/16, or 8/16. The check matrix includes a matrix A with M1 rows and K columns, where M1 represents a predetermined value, and K=N×r represents an information length of the LDPC code, a matrix B with M1 rows and M1 columns in a dual diagonal structure, a matrix Z with M1 rows and N-K-M1 columns that is a zero matrix, a matrix C with N-K-M1 rows and K+M1 columns, and a matrix D with N-K-M1 rows and N-K-M1 columns that is an identity matrix. The matrix A and the matrix C are represented by a check matrix initial value table. The check matrix initial value table is a table indicating positions of elements of 1 in the matrix A and the matrix C on a basis of 360 columns and is a predetermined table. The present technique can be applied to, for example, data transmission using the LDPC code.
