Abstract: A low-density parity-check (LDPC) decoding method includes exchanging messages between check nodes and variable nodes based on scheduling information representing an order of exchanging messages between the check nodes and the variable nodes for an LDPC decoding, and performing the LDPC decoding based on the exchanged messages, wherein the scheduling information is determined by manipulating at least one of an order of the check nodes and an order of the variable nodes in an LDPC bipartite graph.

Abstract: An image signal processor includes a buffer and a buffer controller configured to divide the buffer into a plurality of slots. The buffer controller is configured to store image data necessary for image distortion correction to the buffer. The buffer controller is configured to not store image data unnecessary for image distortion correction to the buffer.

Abstract: A system and method for processing a digital video signal corresponding to an image are provided. A plurality of independent edge detecting processes or edge detector modules detect a set of edges and at least one additional edge that is not included in the set of edges. An edge map includes data regarding all edges identified by any edge detecting process or module, and a visually perceptible artifact of the image is altered based at least in part on an evaluation of the edge map. The system and method detects and filters block artifacts and ringing or other noise from digital images, resulting in reduced image distortion.
