Dear Q.11-14 Experts, I have put a delayed contribution to September SG16 meeting as ftp://standard.pictel.com/avc-site/Incoming/H450Comm.doc The title is "Comments on the Recommendation H.450.1, H.450.2 and H.450.3". In the Telecommunication Technology Committee(TTC) in Japan, they generate their standards based on the ITU-T recommendations considering national matter items and so on. Through their activity related ITU-T H.450.1, H.450.2 and H.450.3, a number of problems are found. The contribution is prepared to discuss Implementers' guide. But, I'm mistake a filename. Please ignore "H450Com.doc". I will submit this contribution to ITU-T in a few days.
