Decoding apparatus, reception apparatus, encoding method and reception method

Abstract

A decoding apparatus includes input circuitry configured to receive coded data; and decoding circuitry configured to decode the coded data to obtain decoded data. The coded data are generated by using an encoding process at an encoding apparatus. The encoding process includes: (i) repeatedly collecting first data blocks included in the decoded data to generate at least one second data block; (ii) dividing at least one third data block included in the decoded data into fourth data blocks; (iii) allocating fifth data blocks included in the decoded data to respective sixth data blocks without collecting the first data blocks or dividing the at least one third data block; and (iv) performing an error correcting encoding on the at least one second data block, the fourth data blocks, and the sixth data blocks in accordance with a coding rate selected from a plurality of coding rates to generate parity data.
