CPC: Input-only peripherals , e.g. global positioning system [GPS]

Full Title

Full titles differ between systems:

IPC:

Selective content distribution, e.g. interactive television or video on demand [VOD] > Client devices specifically adapted for the reception of, or interaction with, content, e.g. STB [set-top-box]; Operations thereof > Structure of client; Structure of client peripherals > Input-only peripherals, e.g. global positioning system [GPS]

CPC:

Selective content distribution, e.g. interactive television or video on demand [VOD] (real-time bi-directional transmission of motion video data H04N7/14 ) > Client devices specifically adapted for the reception of or interaction with content, e.g. set-top-box [STB]; Operations thereof > Structure of client; Structure of client peripherals > Input-only peripherals , e.g. global positioning system [GPS]

CPC subdivides this area 3x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2011.
