    摘要： An iterative decoder dynamically controls the number of local iterations of error-correction decoding performed for each global iteration of channel detection. In so doing, the iterative decoder (i) limits the number of local iterations that are performed after error-correction decoding has likely encountered a trapping set and (ii) permits decoding to continue when error-correction decoding is on the path to converging on a valid codeword. To predict whether error-correction decoding is on the path to encountering a trapping set or converging on a valid codeword, a model is generated based on observed numbers of unsatisfied check nodes for a specified number of local iterations. For local iterations following the specified number of local iterations, the observed numbers of unsatisfied check nodes are then compared to the model to determine whether to continue or terminate local iterations of error-correction decoding.

    摘要： In video quality control and estimation, the joint evaluation of compression artifacts and channel artifacts is a problem. The invention considers the joint perception of both a compression artifact level Dm(V) and a channel artifact level Dh(V) in a method for calculating overall distortion in a video being affected by compression artifacts and channel artifacts. The method comprises a step of adding a compression artifact level Dm(V) and a summand S that is derived from log (Dh(V)) multiplied with a factor that decreases with increasing compression artifact level Dm, such as D(V)=Dm(V)+c·(K−Dm(V))·log(Dh(V)). The result obtained is a measure for the overall distortion.

    摘要： A probabilistic approach of symbol error estimation is disclosed. The probabilistic approach of symbol error estimation reflects the number of symbol errors more precisely than the number of unsatisfied checks. The more precise quality metric calculated in accordance with the present disclosure allows a codec system to achieve a better overall performance. In addition, many other features that previously depend on the number of unsatisfied checks as the sector quality metric may also benefit by adopting the more precise quality metric.
