- Abstract
- A method and apparatus for generating frames to apply error correction to data including a plurality of consecutive data groups are provided. Upon receiving input of an n-th data group consisting of a plurality of priority groups with different priority levels, the number of first code rate frames, which is the number of frames in the n-th data group for which a first code rate is used, is calculated based on the number of first code rate bits calculated based on the ratio of the length of data in an (n−1)-th data group for which the first code rate is used. The number of second code rate frames, which is the number of frames in the n-th data group for which the second code rate is used, is calculated based on the number of second code rate bits calculated based on the number of first code rate bits. Frames for error correction are generated based on the number of first code rate frames and the number of second code rate frame
