Abstract:
A method whereby the frequency of the clock of an internal bus of a sink of High Definition Multimedia Interface (HDMI) data is reduced, and possibly deep color mode of a sink deactivated, in response to an inability of a source of HDMI data to read extended display identification data (EDID) and/or effect High Definition Content Protection (HDCP) authentication with the sink.
