discarded, including NO. 0 media packets, 5th media packs, and NO. 0 redundant packets. The receiving FEC is unable to recover because the number of packets received is 8 plus the number of redundant packets received is 1, the total is less than the total number of media packets (10). For the second group, only two media packets are lost and can be recovered normally. The experimental results shown in Figure 5 show that the inference is correct, No. 0 media packets, 5th media packets are lost,
