Claim 10:
11. A method for transmitting a bitstream generated by an image encoding method, the image encoding method comprising:
deriving a target boundary of a deblocking filter;
determining a maximum length of the deblocking filter for a target boundary of a reconstructed block; and
applying the deblocking filter for the target boundary based on the maximum length,
wherein, based on the target boundary being a vertical boundary:
the maximum length is determined based on a width of a first block adjacent to a left side of the target boundary or a second block adjacent to a right side of the target boundary,
the maximum length comprises a first maximum length at first block side and a second maximum length at second block side, and
based on a width of the first block being equal to or less than 4, the first maximum length and the second maximum length are determined to be 1, and

wherein, based on the target boundary being a horizontal boundary;
the maximum length is determined based on a height of a third block adjacent to an upper side of the target boundary or a fourth block adjacent to a lower side of the target boundary,
the maximum length comprises a third maximum length at third block side and a fourth maximum length at fourth block side, and
based on a height of the third block being equal to or less than 4, the third maximum length and the fourth maximum length is determined to be 1.
