The present invention discloses video data encoding and decoding methods and apparatuses, which relates to the field of encoding and decoding technologies, and can improve transmission flexibility and enhance robustness. The encoding method provided in the present invention includes: determining a to-be-encoded information group in a to-be-encoded video sequence; generating a primary information group corresponding to the to-be-encoded information group, wherein the primary information group comprises first data information, indication information that indicates whether the to-be-encoded information group is a primary information group or a redundant information group, and location information of the primary information group; generating a redundant information group corresponding to the to-be-encoded information group, wherein the redundant information group comprises second data information, location information of the redundant information group, indication information that indicates whether the to-be-encoded information group is a primary information group or a redundant information group, and location relationship information of the redundant information group and the primary information group; and encoding the primary information group and the redundant information group into a bitstream. |
