ABSTRACT:
Methods and apparatuses are provided for adaptive entropy encoding and adaptive entropy decoding using various context models. A scalable entropy encoding method includes determining a context by referring to both syntax elements in the same layer as a block including a syntax element to be encoded and syntax elements in lower layers or only the syntax elements in the lower layers and performing entropy encoding on the syntax element using the determined context.
