Abstract
Provided is a filtering apparatus, method, and medium for a multi-format codec, in which a blocking artifact of decoded video data is removed. The filtering apparatus includes a compression format detection unit, a block strength determination unit, a table determination unit, and a first filtering unit. The compression format detection unit detects a video compression format of the decoded video data. The block strength determination unit determines a block strength indicating a filtering strength with respect to the decoded video data according to the detected video compression format. The table determination unit determines a filtering table differently according to the block strength when the block strength is greater than a predetermined threshold. The first filtering unit performs filtering on the decoded video data in units of a block using the determined filtering table.
