Introduced: January 2018

Title

Titles differ between systems:

IPC: Processing image signals

CPC: Processing image signals (for multi-view video sequence encoding H04N19/597)

Full Title

Full titles differ between systems:

IPC:

Stereoscopic video systems; Multi-view video systems; Details thereof > Processing, recording or transmission of stereoscopic or multi-view image signals > Processing image signals

CPC:

Stereoscopic video systems; Multi-view video systems; Details thereof > Processing, recording or transmission of stereoscopic or multi-view image signals > Processing image signals (for multi-view video sequence encoding H04N19/597)

Of 12 combined children, 11 exist in both systems.

1 codes are CPC-only extensions.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2018.
