Abstract

A method, medium, and apparatus for encoding and/or decoding video by generating a scalable bitstream formed of a base layer bitstream and an enhancement layer bitstream so as to have forward compatibility, wherein the enhancement layer bitstream comprises a bit-depth field of the enhancement layer, a frame or a picture type field of the enhancement layer in consideration of a frame or a picture type of the base layer, an additional quantization information field for obtaining a quantization parameter of the enhancement layer together with a quantization parameter of the base layer, an intra-macroblock field of the enhancement layer, and an inter-macroblock field of the enhancement layer.
