When distributing a set 101 of frames 102 each with encoded data 103 from a transmitter 104 to a receiver 105, a dependent frame 108 requires an independent frame 107 for decoding, and the transmitting 111 of the frames 102 from a buffer 110 at the transmitter 104 is reordered such that the dependent frame 108 is sent after the independent frame 107. In particular, a transmission policy wherein buffering 109 a further frame 125 takes into account both: if the further frame 125 requires zero, one or two frames 102 of the set 101 for decoding, and the current frames 102 buffered at the first and the second position 123 of the transmit buffer 110.
