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 > Processing of content or additional data, e.g. demultiplexing additional data from a digital video stream; Elementary client operations, e.g. monitoring of home network or synchronizing decoder's clock; Client middleware > Interfacing a local distribution network, e.g. communicating with another STB or inside the home

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 > Processing of content or additional data, e.g. demultiplexing additional data from a digital video stream; Elementary client operations, e.g. monitoring of home network or synchronising decoder's clock; Client middleware > Interfacing a local distribution network, e.g. communicating with another STB inside the home
