HDMI Compliance Testing

Compliance Testing Mandated by HDMI Adopter’s
Agreement
–
–
–

Authorized Testing Center
–
–
–

Promotes compatibility between devices
Checks compliance with HDMI specification
Required for a product to bear the HDMI logo
Initial product testing must be done at ATC
First product in a category (sink, source, repeater, cable) from each
company
Subsequent products may be self-tested by manufacturer
Current locations:
–
–
–
–
Silicon Image, California, USA
Matsushita, Osaka, Japan
Philips, Cannes, France
See www.hdmi.org for specific contact information

Achieving Full Interoperability

Rapid introduction of HDMI has led to
interoperability failures as manufacturers
rush to market with a range of
implementation quality

Many failures are related to poor HDCP
implementations with no way of testing

Ad hoc testing of HDCP not sufficient
