NPD

NPD is a packet format used on PS3 in NPDRM contents. It corresponds to 2 sort of packets: the ones in SDAT/EDAT files and the ones in SELF/SPRX NPDRM header in NPDRM Selfs only. NPD stands for Network Playstation Data or Network Playstation Drm. PS Vita equivalent is "DRM".

It is required to compare these 2 sort of packets before stating if they have same usage and what the common name should be.
