CPC: Systems for the transmission of television signals using pulse code modulation (H04N21/00 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Television systems > Systems for the transmission of television signals using pulse code modulation

CPC:

Television systems (details H04N3/00, H04N5/00; methods or arrangements, for coding, decoding, compressing or decompressing digital video signals H04N19/00; selective content distribution H04N21/00) > Systems for the transmission of television signals using pulse code modulation (H04N21/00 takes precedence)

CPC subdivides this area 3x more granularly than IPC with 2 additional codes.

2 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

1 shared codes have differing titles between IPC and CPC.
