| // This file contains a set of packets masks for the FEC code. The masks in |
| // this table are specifically designed to favor recovery of bursty/consecutive |
| // loss network conditions. The tradeoff is worse recovery for random losses. |
| // These packet masks are currently defined to protect up to 12 media packets. |
| // They have the following property: for any packet mask defined by the |
| // parameters (k,m), where k = number of media packets, m = number of FEC |
| // packets, all "consecutive" losses of size <= m are completely recoverable. |
| // By consecutive losses we mean consecutive with respect to the sequence |
| // number ordering of the list (media and FEC) of packets. The difference |
| // between these masks (|kFecMaskBursty|) and |kFecMaskRandom| type, defined |
| // in fec_private_tables.h, is more significant for longer codes |
| // (i.e., more packets/symbols in the code, so larger (k,m), i.e., k > 4, |
| // m > 3). |
