Method and apparatus for encoding/decoding video using split layer

A video encoding apparatus, comprising:

• a macroblock size candidate setting unit for setting macroblock size candidates;
• a video encoder for encoding an input image by each of the macroblock size candidates;
• a macroblock size determiner for determining a macroblock size based on an encoding cost for each of the macroblock size candidates, and generating a bitstream including an image data encoded in a determined macroblock size and information on the determined macroblock size.

• and
• a video decoder for decoding an image through reconstructing a current block by decoding an encoded image data extracted from the bitstream, by using a minimum subblock size depending on a reconstructed maximum partition layer value.

A video decoding apparatus, comprising:

• a macroblock size setting unit for setting a macroblock size through extracting a macroblock size information from a bitstream and setting the macroblock size by using an extracted macroblock size information;
• and
• a video decoder for decoding an image through extracting an encoded image data from the bitstream and generating a reconstructed image by decoding the encoded image data depending the macroblock size identified by the macroblock size information.
