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.

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： An apparatus and method configure RTCP packets in a control feedback handling in multimedia sessions. The apparatus and method are configured to provide sending of any RTCP individual packet as a non- compound RTCP packet an order within a time interval. The apparatus and method are configured so that an excessive length of compound RTCP packets are handled by fragmenting each compound RTCP packet in smaller non-compound packets and sending it spaced over time. The apparatus and method guarantee RTCP non-compound packets to provide an equivalent functionality as the RTCP compound packets by providing the same information to the receiver, and the receiver does not lack any feedback information. The apparatus and method are also configured to use semi- compound RTCP packets, where at least two non-compound/individual RTCP packets (but less than all the non-compound/individual RTCP packets that would be sent as compound packet) are sent together as a semi- compound RTCP packet.
