Patent ID: 6909751

Claim:
A device for processing coded data blocks included in a sequence of coded digital images (ES) according to a block-based coding technique, said device comprising: a post-processing circuit ( 33 ) able to effect a horizontal processing of data blocks of an image, associated with a vertical processing of said blocks, the horizontal or vertical processing comprising a unitary processing of a first block, the unitary processing of a second block adjacent to said first block and a double processing of the concatenation of the first and second blocks, the post-processing circuit being able to supply concatenated blocks of processed data comprising blocks of completely processed (Bc), partially processed (Bi k+1 ) and pre-processed data (Bb), the pre-processed data being intended to be reused by the post-processing circuit, a decoding unit ( 21 ) able to receive the coded data blocks and to supply decoded datablocks (B) to the post-processing circuit, a memory interface ( 32 ) able to supply data blocks already partially processed (Bi k ) to the post-processing circuit, and to store the partially processed data blocks (Bi k+1 ) for subsequent processing by the post-processing circuit as well as the completely processed data blocks (Bc) for display on a screen ( 24 ).
