Why is HDMI Seemingly so Messed Up? Some History Some Problems Why the Problems The HDMI Version Numbers The Future Open Forum
Agenda
Worked at HDMI Licensing, LLC ◦ 2006 to 2009◦ First Person in Charge of Compliance◦ Interop Group◦ Handled All Major Functions
Kordz USA, Inc.◦ USA Operations Since 2009◦ IC Realtime Master Distributor
Background
No locking Connector – Falls out? Never Seems to Work Right? Doesn’t Go Long Distances? No Field Termination? Version Numbers All over the Place? Finicky and Touchy? Not Easy to Work With? Expensive? Who Designed This Anyway?
So, Why IS HDMI Sooo Messed Up?
Adopters, By the Numbers◦ Q1CY06 = 365◦ Q1CY07 = 574◦ Q1CY08 = 828◦ Q1CY13 = Over 1300 Adopters!
Over a BILLION Units! ALL New HDTV’s produced have HDMI
◦ The Founder’s “Home Run” Number(s)? Adopters? Units?
Let’s Look At Some History - Adopters
Originated by Silicon Image ◦ Semi-Conductor Company (Not CE)
DVI on Steroids◦ Add Audio, and Viola!
Originally Intended for Networking/Computers◦ Not Originally intended for CE
Always Backwards Compatible◦ Even with DVI?◦ No locking…?
More HDMI History - Technology
Where Did the “Founder’s” Come From?◦ The Story Behind the Founders◦ The Players Who Made this Happen
Wrong industry? What Does Hollywood Have to Do With
Technology?◦ Yes, Content Protection, HDCP◦ Remember the Record Industry???
More HDMI History – The Players
Sony Panasonic Silicon Image Hitachi Phillips Thompson Toshiba
You Got To Love A Founders Meeting!

What Kinds of Compliance◦ Trade Mark◦ Product
How To Ensure Compliance◦ Know your Suppliers
Problems With Compliance◦ Enforceable?
Different Country Laws Staffing Moving Targets
HDMI Problems - Compliance
The Specification Gotchas◦THE Definition of HDMI – From a Technical
Standpoint◦ Min and Max◦ Implementation is up to the Manufacturer
Varying Degrees of Quality/Price◦ Most make what the clients want – kind of.◦ You get what you pay for.
Manufacturers Interpretation◦ Sometimes, it gets lost in the translation…
Cutting Corners (manufacturing)
HDMI Problems – Quality
Piracy is Rampant◦ Sometimes from Legit Manufactures (overruns)◦ Sometimes Small shops (for a quick $$$)◦ Sometimes from Coordinated Business Practice
China Connection◦ Government Getting Better, but…◦ Who pays is important
How Do you Tell?◦ Super Important to Work With Trusted Partners◦ Realistically, sometimes you cannot tell a pirated
until its too Late
HDMI Problems – Non-Adapters
EDID Read (Handshake) Cables (Handshake) HPC Detect Repeater Support Different Manufacturers Interpretation (See
CEC) Quality – Again! For the most part, many of these issues are
going away – Thankfully!
HDMI Problems – The Biggies
Process for Becoming an Adopter Only One Entity in the Whole Chain…
◦ Section 6.2 What an Adopter Agrees to Do Types of Adopters (2 Types) Royalties Administration of the Agreement
Sometimes, it’s not so cut and dry!
The Adopter Agreement
Groundwork for the Process◦ Testing Guidelines
First Source, Sink…◦ Really, this is the process!?!?!?
Self Testing◦ Yup, Self Testing
Self Regulation◦ Yup, Self Regulation
Testing Centers◦ ATC’s = Certified◦ Other, non-certified ◦ One in between (Simplay Labs)
The HDMI Testing Process
Brief History of Versions◦ 1.0 – 1.1 – Mostly Around Interpretation (2002-2004) No
Compliance◦ 1.2 – 1.2a – Mostly CEC (2005) No Compliance◦ 1.3 – 1.3a – Repeater Support, High Speed, Finally
Compliance! (2006)◦ 1.4 – 1.4a – Ethernet, ARC, Compliance Focus, No Version
Numbers - Cables◦ What about 1.3b, 1.3c, etc????
Trademark and Logo Guidelines◦ 2007 – First attempt of Compliance thru Trade Mark
No Version Numbers – Current Stance◦ What if I see Version Numbers?
Really, What’s the Version?
Buy from HDMI Adopters◦ A Higher Standard◦ Check Out www.hdmi.org
Purchase Known Quality◦ Sometimes, low cost can cost you (Value)
Test Before Installation◦ You Would be Surprised on how many still don’t..
Know The HDMI Gotchas Backwards Compatibility – Know This
◦ HDMI will always “Dumb Down” to the lowest version number.
◦ What about that extender?!?!
Some Fixes!
The New 4K/ULTRA Format◦ Requires more Juice, 300Mhz Silicon
The Industry has Been Lazy◦ Easy for the last 6 Years
For the First Time Ever, we are Testing the Limits of the HDMI Specification◦ Still not there, but 8.91Gbps is close
The Truth About “High Speed”◦ Definition of “High Speed” vs “Standard Speed”◦ NOT required to run 1080p◦ What are those cables “in the wall”?
The Opportunity
4K◦ It’s Here◦ Adoption Rate less then 1080p (3-4 years – MAX)◦ You will find out about the interconnects –
Unfortunately. New Open Forum
◦ Crazy Times at HDMI – Herding cats!◦ Fall, 2013 (Please, Hold your Breath!)
Technology and Beyond◦ Proposed doubling of the 4K/ULTRA Specification
The Future of HDMI
No locking Connector – Falls Out? Never Seems to Work Right? Doesn’t Go Long Distances? No Field Termination? Version Numbers All over the Place? Finicky and Touchy? Not Easy to Work With? Expensive? Who Designed This Anyway?

Q and A Forum
HDBaseT Addendum
Valens Semi Conductor Already on Specification 2.0 No Trademark and Logo Guidelines until 2.0
Specification? No Royalties – Yet? The Technology
◦ Stable◦ NOT the HDMI “Killer” as Advertised◦ Basic Technology is one to scramble and then
reconstitute the signal.
