摘要： A hybrid-padding approach for arranging variable size data packets for error correction encoding and decoding is disclosed. The approach can involve arranging the data packets in columns and rows and selecting the row size to minimize the amount of padding required. If data packet is smaller than the number of rows the data packet is inserted into the column and the remaining rows are padded. If the data packet is larger than the number of rows, the data packet is allowed to span multiple columns with the last column being padded if necessary. The data packets can include parameters, such as a source block number, packet length, and starting column number, and the error correction packets can include parameters, such as, a source block number an N, a K, the starting column number, and the number of row, to signal the hybrid-padding message.
摘要翻译：公开了一种用于布置用于纠错编码和解码的可变大小数据分组的混合填充方法。该方法可以包括将数据分组排列成列和行，并选择行大小以最小化所需的填充量。如果数据包小于数据包插入列的行数，剩下的行被填充。如果数据包大于行数，则允许数据包跨越多个列，如果需要，最后一列被填充。数据分组可以包括诸如源块号，分组长度和起始列号的参数，并且纠错分组可以包括诸如源块号N，a，起始列号和行数，表示混合填充消息。

摘要： The invention relates to the generation of error correction data for available data packets 53 and to the reconstruction of missing data packets based on available data packets and available error correction data. In order to enable an efficient error correction, the data packets 53 are distributed at an encoding end to at least one block of data symbols 54, each data symbol 54 being of equal size (steps 403,404). Then all data symbols 54 of a respective block are used in an encoding operation for forming a respective one of at least one error correction symbol 56 for this block (step 405). At a decoding end, received data packets 83 are distributed again to a block of data symbols 84 and missing data packets are reconstructed based on these data symbols 84 and on error correction symbols 86 associated to the block.
