  2. Differences w.r.t. previous version Changes Clarified text, etc. Removed the IPR section too A point that we need to discuss Remark from Brian: is it possible to have an FPI format optimized for GF(28) codes instead of having the same FPI for all GF(2m) codes? Our proposal: the FPI is composed of two variable length fields Source block number: 32-m bits long Enc. Symbol ID: m bits long

  3. Differences w.r.t. previous version... (cont') if m=8: if m=16: where m defines the GF size (GF(2m)) and is carried in the FEC OTI  m is known before FPI are used! Is it acceptable? We think it's in line with the FEC BB I-D... If yes, then the I-D is ready for WGLC 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Source Block Number (24 bits) | Enc.
