摘要 |
Device and method for inserting error correcting codes and for reconstructing data streams, and corresponding products The present invention relates to a device (1) for inserting error correcting codes into data streams (11) intended to be sent in packets in a network (8 ), a device (9) for reconstructing data streams (13), and corresponding methods and products. The insertion device comprises a unit (3) for identifying resynchronization indicators dispersed in the data streams and a unit (4) for determining successive segments in these streams, the segments forming partitions of the data lying between two consecutive resynchronization indicators. It also comprises a unit (6) for allocating a set of error correcting codes to each of these segments, these sets of codes having decreasing sizes between any two of the consecutive resynchronization indicators. Preferably, the device also comprises a data interleaving unit (7).
