摘要： The packet interleaving method includes selecting successive input sets of consecutive input packets (X1 . . . XNin) received from a forward correction module (14), each input packet (Xj) being a vector of constellation points of a predetermined constellation diagram. For each input set, it further includes generating an output set of output packets (O1 . . . ONout), each output packet (Om) being a vector of constellation points, by distributing the constellation points of each input packet (Xj) of the input set, and sending the output packets (O1 . . . ONout) of the output set to a modulator (18). The input set including Nin input packets (X1 . . . XNin) and each of the Nin input packets (X1 . . . XNin) including a same number Lin of constellation points, the number Nout of output packets in the output set is related to Lin by the relation Lin=A×Nout, where A is a fixed whole number.

摘要： A method of managing the storing of data packets into storage space of a buffer, in which each data packet is constituted of at least two data blocks includes the steps of receiving (40) the data blocks of a current data packet and writing (42) in free storage space of the buffer the data blocks of the current data packet as received. If there is not enough free storage space in the buffer (12) for writing a received data block of the current data packet, the method continues with ceasing (48) to write received data blocks of the current data packet, and defining (48) at least one written data block of the current data packet as free storage space, so that received data blocks of a next data packet can be written over the written data blocks of the current data packet. The method has application to digital television reception.
