<p>The invention relates to a method for assembling FEC frames for a sequence of groups of coded media packets. In order to reduce a buffer delay at a decoding end (15), it is proposed that the FEC frame is aligned with the groups of media packets. To this end, a number of next subsequent groups is determined, which fit completely into a FEC frame. All coded media packets associated to this determined group or groups, if any, are selected for the FEC frame (step 202,402). Then, the selected coded media packets are encoded to obtain at least one FEC packet for the FEC frame (step 206,406). For fixed FEC frame structures, moreover the introduction of padding packets as additional media packets, if required, is proposed.</p> |
