The document summarizes changes made from HDMI specification 1.3b to 1.3c, including changes to test methods and criteria. Key changes include: - Revising the maximum dimension for Type C cable tips to 6.3mm. - Adding valid connection and no connection test methods for cable types other than wire. - Modifying TMDS data eye diagram and impedance measurement test methods and criteria for active and converter cable types. - Adding specifications for measuring DDC/CEC capacitance and voltage depending on the cable type and connections.

2. Feature Changes from HDMI 1.3b to 1.3C
• changed overmold dimension of Type C cable
to the tip of the shell to 6.3mm.
• Test method for active,converter and passive cable
• defined valid connection and valid noconnection
for cable type is not quot;wirequot;
