FIELD: physics, video.
SUBSTANCE: invention relates to video encoding and decoding means for encoding and decoding symbols having a hierarchical structure. The video encoding method includes encoding a picture of a video based on data units having a hierarchical structure; determining symbols of the encoded picture based on the data units having the hierarchical structure; determining an encoding method of the symbols based on characteristics of symbols, which are determined based on the data units having a hierarchical structure; and encoding and outputting the symbols according to the determined encoding method.
EFFECT: wider range of equipment.
