Re: Rmt Digest, Vol 66, Issue 8

I see.  However, I'm not sure that this qualifies as an "errata", or is simply a waste of 16 bits in the FEC OTI.  On the other hand, as it is now, the FEC OTI is essentially the same for all the schemes described in this document (the only difference that I saw is that in some there is a "reserved" field whereas in others this reserved field is the FEC Instance ID), so there is the advantage that they are all the same.  Also the overall FEC OTI is not very long to start with and only needs to be received once per object, so the wastage is pretty minimal.  However, I don't have a strong opinion either way so if people feel that this rises to the level of an error that deserves an errata, that is fine with me.

According to the text from RFC 5445 Section 3.2.2.2:

"Maximum-Source-Block-Length: a non-negative integer, less than 2^^32,
indicating the maximum number of source symbols in a source block"

it's in "symbols"  ...

So the question is whether a 32-bit symbol id was intended or if the
block length should be 16-bits.  I would _guess_ the latter was the
intention given this is the _compact_ no FEC scheme?
