[Mp4-tech] two questions on H.264 HRD

[Nancy Johnson]

Dear H.264 experts,
  Could you please help me to figure out these 2 questions?
  1. For HD-DVD decoding application, is it necessary for the H.264 decoder to claim output timing decoder conformance? It seems that for this case the decoder can be fed the bit stream in an "on demand" way.
  2. According to page 267 equation C-7 of H.264 03/2005, the removal time of the access unit from the CPB will be influenced by initial_cpb_removal_delay[SchedSelIdx]. Although initial_cpb_removal_delay[i] (i=0~cpb_cnt_minus1) are sent to HRD by buffering period SEI message (page 277 section D.1.1 of H.264 03/2005), I can not find a way in the H.264 stream definition for the HRD to know the specific value of SchedSelIdx in equation C-7. If this is true, how to make sure the value of SchedSelIdx in equation C-7 used by DUT are the same as that used by HRD? (Is this necessary for the decoder to meet output timing conformance?)
  Thanks a lot.
  Sincerely yours,
  Nancy Johnson
