[Hdot264-devel] doubt in jvt standard

hi all,
i have some doubts in jvt standard.
the standard says, if constrained_intra_pred_flag is
equal to 0, we can use the neighbouring inter
macroblock residual data and decoded samples for the
prediction of intra macroblocks. that means the
current macro block is coded in intra prediction mode
and left or top macroblock is coded in inter 
prediction mode. but the prediction mode (intra or
inter) is same for all macroblocks within the same
slice. which implies the neighbouring macroblocks
belong to a different slice. if such is the case that
macro block is not available for the current macro
block as per the standard. then no question of
considering any of the params of neighbouring macro
blocks. can any one explain where i am going wrong.

thanks and regards
mohan

constrained_intra_pred_flag refers to Intra-MB withing Inter-Slice.
In this case the neighboring MB can be either I or P (B,SP) and the 
intra prediction can be restricted to only neighboring Intra MB.
