Dear Mr. Baese, experts,
concerning your document APC 2018 "Protection Procedure": c) If the protection is actually done with level p-1 why do one has to keep level p somehow ? In opposition to the written text is packet #3 in your figure.
d) Can you please explain the meaning of "packet" in every case it is mentioned within this paragraph ?
The grouping rule in the protection procedure is now reworded. It now reads:
a. A media packet can only be protected at each protection level once.
b. For a media packet to be protected at level p, it must also be protect at level p-1.
c. If an FEC packet contains protection at level p, it must also contain protection at level p-1.
I hope it is clearer now. Let me know if there is any further questions.
We are supposed to perform the test reproducible for everybody else within the standardization community. Which public available software for H.263 we are going to use ?
This question may be better answered by Q.6/16 (Video Coding Experts Group), who works on standardizing the H.263 video codec. All the algorithms for H.263 are detailed in the H.263 and TMN documents in Q.6. As far as I know, UBC (University of British Columbia) has a (semi-official) sample software implementation of the codec.
Hope it helps.
