// 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).
