DEBLOCKING FILTERING METHOD AND APPARATUS

摘要

The present invention relates to a deblocking filtering method and deblocking filtering apparatus. The deblocking filtering method according to the present invention comprises the following steps: setting a boundary strength (bS) for a block edge in a unit sample block consisting of recovered chroma components; determining deblocking filtering for said block edge on the basis of the bS; and applying a deblocking filter to said chroma components in accordance with the deblocking filtering determination. According to the present invention, the size of said unit sample block may be set in accordance with a sampling format of a chroma sample.
