Interleaving method and device, and deinterleaving method and device

摘要

The present invention relates to an interleaving device with error protection, comprising a separator configured to divide at least one frame of data into categories of data according to error sensitivities of the data in the categories, an encoder configured to perform different types of error coding on the divided data to provide them with different error correction capacity, and an interleaver configured to rearrange the categories of data after encoding thereof so that a data category with higher error correction capacity is arranged at equal intervals in a data category with least error correction capacity.
