RE: [rohc] SigComp User Guide, deflate bytecode

Hi,

I hope I'm not too late but I just saw a posting dated from 14 Mar 2005 (see below). After reading the User Guide, I thought the extra "ff ff" may have been placed there for the sake of record marking in a stream-based application. Does this make sense ?

You're right, it does.
They don't break anything by being there because although the sentinel of 7
bits of zero is not necessary (as the draft says) it just happens that in
this message the total number_of_bits_needed mod 8 = 1 so we do have the 7
bit sentinel to make the message byte aligned. Any bytes beyond it are
ignored.

I'm not sure why the bytes are there and they're not needed, so I'll remove
them.

Thanks for pointing it out.

Best regards,

Abbie
