DIFF Subgroup
H04N 13/366 using viewer tracking
Introduced: January 2018
Full Title
Full titles differ between systems:
IPC:
Stereoscopic video systems; Multi-view video systems; Details thereof > Image reproducers > using viewer tracking
CPC:
Stereoscopic video systems; Multi-view video systems; Details thereof > Image reproducers (optical systems for producing stereoscopic or other three-dimensional [3D] effects G02B30/00) > using viewer tracking
IPC and CPC are identically structured here. All 7 subcodes exist in both systems.
IPC defines codes here since 2018.
