Re: Please all respond: Call for the ipdvb WG to adopt: draft-fair-ipdvb-ar-04.txt

[Fausto Vieira <fvieira@sunaut.uab.es>]

Dear all,

This is the first time I see this document.

I also vote for WG ID.

Nonetheless, here are my remarks on the current version of the document:

The following sentence is duplicated in the draft (page 5):
"The all 1s PID value indicates a Null TS Packet introduced to maintain 
a constant bit rate of a TS Multiplex. There is no required relationship 
between the PID values used for TS Logical Channels transmitted using 
different TS Multiplexes."

This sentence is also duplicated (page 5):
"PSI: Program Specific Information [ISO-MPEG2]. PSI is used to convey 
information about services carried in a TS Multiplex. It is carried in 
one of four specifically identified table section constructs 
[ISO-MPEG2], see also SI Table.

Spelling error:
"Multicast address resolution occurs at one level in associating a 
specific L2 address with _am_ IP Group Destination Address"
Change the underlined to "an"

Spelling error:
"The principle drawbacks are that _while_ the INT, there is a need for a 
Gateway to introduce associated PSI/SI MPEG-2 control information."
Change the underlined to "with"

Spelling error:
"(...) or parts of the network where gateway devices isolate the MPEG 
devices from the larger Internet creating virtual MPEG2 private networks.)"
Move the last parentheses to before the period mark.

Spelling error:
"The ND protocol of IPv6 [RFC2461] may be used.NDP does not require (...)"
Insert a <space> after the period mark.

Spelling error:
"The ND protocol of IPv6 [RFC2461] may be used with The LLC/SNAP format 
of MPE.  NDP does not require(...)"
Remove the 2nd <space> after the period mark.


Cheers

Fausto Vieira
