Video coding systems or apparatus utilizing context-based adaptive binary arithmetic coding (CABAC) during encoding and/or decoding, are configured according to the invention with an enhanced binarization of non-zero Delta-QP (dQP). During binarization the value of dQP and the sign are separately encoded using unary coding and then combined into a binary string which also contains the dQP non-zero flag. This invention capitalizes on the statistical symmetry of positive and negative values of dQP and results in saving bits and thus a higher coding efficiency.

The present invention provides a method for decoding a low density generator matrix code (LDGC), applied for decoding transmitted original information bits encoded in LDGC code. The method comprises the following steps: A: deleting a part erased by a channel in a received code word sequence R filled by a known bit sequence to obtain an erased code word sequence Re, and deleting the rows corresponding to the erased part from a transposed matrix GIdgct of a generator matrix of the LDGC to obtain the erased generator matrix Ge; B: permuting columns of Ge such that an M-order square matrix with an element in the 0th row and 0th column being a vertex is a triangular matrix to obtain the permuted generator matrix Gf; and C: calculating the original information bits using Gf and Re.

Systems and methods are provided for implementing various aspects of a Reed-Solomon (RS) error-correction system. A detector can provide a decision-codeword from a channel and can also provide soft-information for the decision-codeword. If the decision-codeword corresponds to an inner code and an RS code is the outer code, a soft-information map can process the soft-information for the decision-codeword to produce soft-information for a RS decision-codeword. A RS decoder can employ the Berlekamp-Massey algorithm (BMA), list decoding, and a Chien search, and can include a pipelined architecture. A threshold-based control circuit can be used to predict whether list decoding will be needed and can suspend the list decoding operation if it predicts that list decoding is not needed.
