As far as I know, constrained intra in HEVC is the same as it was in
AVC. When generating intra predictions in inter blocks, only
intra-coded reference pixels are used. Inter-coded reference pixels
are replaced with intra-coded neighbor pixels or default values. The
general idea is to block the propagation of reference errors that may
have resulted from lossy signals.
If anyone has a better description, please speak up
