The invention concerns a multi-standard deblocking filter for deblocking video images including a deblocking unit arranged to perform deblocking on edges of a current macroblock of an image based on samples taken from a first sample window comprising said current macroblock and a second sample window adjacent to said first sample window; three memory banks (510, 511, 512) coupled to said deblocking unit, a first one of said memory banks arranged to store samples of said first sample window, a second one of said memory banks arranged to store samples of said second sample window, and a third one of said memory banks arranged store samples of a third sample window adjacent to the second sample window comprising a macroblock deblocked in a previous deblocking operation; and control circuitry arranged to control, during a same macroblock deblocking operation, loading and deblocking of said current macroblock and outputting of samples of said third sample window from said third one of said memory banks. |
