[AVT] Comments on EAC-3 RTP payload format

Hi,

I have reviewed draft-ietf-avt-rtp-eac3-00.txt and have two comments:

1. The definition of bitStreamConfig parameter is not clear on how to 
determine which streams belong to which program. I think there needs to 
be some explanation on the seperator. From the example it seems that a 
requirement to order "i" before "d" and any new "i" is a new program 
would solve the issue.

2. Section 5.2:
"To ensure interoperability with
       receivers which support the AC-3 payload format, but not the
       E-AC-3 payload format, a sender which desires to send an AC-3 bit
       stream in the E-AC-3 payload format SHOULD also offer the session
       in the AC-3 payload format by including attribute lines for both
       media sub-types: 'ac3' and 'eac3'."

I would propose to change "including attribute lines for both" to 
"include payload types for both"

Cheers
