VIDEO DATA ENCODING AND DECODING METHODS AND DEVICES

摘要

The present invention relates to the field of coding and decoding technologies, and discloses video data coding and decoding methods and apparatuses, which can improve coding efficiency or is low in transmission flexibility. The decoding method provided by the present invention includes: determining a first to-be-decoded information group in a to-be-decoded bitstream, where the first to-be-decoded information group includes data information, attribute information, and location information of the first to-be-decoded information group; determining a reference information group set in a case in which the attribute information represents that the first to-be-decoded information group is a redundant information group; and discarding the first to-be-decoded information group if location information of at least one reference information group in the reference information group set is the same as the location information of the first to-be-decoded information group, or parsing the data information if location information of all reference information groups in the reference information group set is different from the location information of the first to-be-decoded information group.
