<br><span style=" font-size:10pt;font-family:sans-serif"> for the

<br>
<ul>
<li>
<li><span style=" font-size:10pt;font-family:Courier New">Sentence 4.4.3,
about LDPC fill data, should be modified as well. Currently it reads as

"The fill
data shall be added before randomization and randomized with the Transfer
Frame." </span>
<br>
<br><span style=" font-size:10pt;font-family:Courier New">Possible Suggestion
could be </span>
<br>
<br><span style=" font-size:10pt;font-family:Courier New">
"The fill

<br>
</span><span style=" font-size:10pt;font-family:sans-serif"><br>
Ken provided a new draft version of the TC Coding Blue Book (231.0-B),
following action AI_19_16.</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt;font-family:sans-serif"><br>
The main change, discussed and agreed in Darmstadt last year, is about
the order inversion of encoding and randomisation when LDPC coding is used.</span><span style=" font-size:12pt">
</span><span style=" font-size:10pt;font-family:sans-serif"><br>
Ken also added an annex with PICs. I don't remember whether this was agreed
(and I don't have any evidence in my minutes) but of course I could have
simply forgotten. In any case,</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt;font-family:sans-serif"><br>
we should have a look and discuss about it.</span><span style=" font-size:12pt">
</span><span style=" font-size:10pt;font-family:sans-serif"><br>
Could you please send your comments by Monday 2 March (4 weeks from now,
as agreed in AI_19_17)?</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt;font-family:sans-serif"><br>
Following this deadline and based on the comments received, I will trigger
the process for the Agency Review.</span><span style=" font-size:12pt">
