Other HDMI useful info uncovered during the adventure:

HDMI Uncensored book - Author, Jeffrey Boccaccio, talking about some aspects of the book…

Part 1 - EDID - DCC and I2C Protocol - problems with insufficient rise time on DCC connection

Part 2 - EDID & TDMS - problems with insufficient 5v due to over current draw

Article about HDMI over Cat5/6 transmission equipment from one of the authors company - DPL labs

Uncited quote from the book re: DCC signal problems and quote repeated here, with citation.

Many useful videos - including some by the book author

HDMI Design and Initialization Sequence - CEDIA - Figure 1 is a very nice summary of the HDCP initialization sequence, including EDID and HDCP

This is a great introduction to HDMI, with considerable detail about HDCP.
