[Sis-mia] Questions on Video Streaming Green Book

Hey,

Attached are some light edits and some questions about the Bundle Streaming Requirements Green Book (the comments in the markup).  Since CESG review is the only thing the Green Book goes through, can I get your feedback on the commented items before I submit to CESG?

Summary of questions:
5.2: The DLR transparent gateway – encapsulates UDP datagrams and is otherwise agnostic to the video protocol running over UDP, yes?
5.2.1: the comment in the second paragraph – is the addition correct or is it the gateway timestamp that’s being used (or something else)?
5.2.2: where you say that MPEG-TS and BP are doing some of the same things (robustness for error-recovery and interleaving) – can you say a bit more on the implications of that?
5.2.2: BP does interleaving?  I’m thinking ‘traditional’ interleaving where data items are assigned to a matrix row-by-row and read out column-by-column once the matrix is full.  I think you’re thinking of something else – can you tell me what it is you mean?
5.4: probably a question for later.
6.1: 10% BER w/ what I assume is LTP red – how does that EVER succeed?  Chances of getting 100 Bytes through correctly at 10% BER are really low.
