HDMI Specification
The HDMI Specification and related documents previously hosted here have been removed due to a DMCA notice from HDMI Licensing on May 6, 2019. The HDMI 1.3a specification is available for free public download directly from the HDMI website anyway here (via a bizarre and seemingly unnecessary "we will email you a one-time download link" system).For convenience, you may access this free publicly available document directly using the links below. Also provided are several older versions (which are similarly non-confidential).

CTA Standards
The CTA standards previously hosted here have been removed due to a DMCA notice from the CTA on May 3, 2019. It is apparent that the CTA disapproves of public access to these standards. Indeed, there is no need to worry however, as these documents can be obtained elsewhere; in fact, the CTA themselves are happy to provide free public access to these very same standards, available for download straight from their own website:
Update May 9, 2019: The CTA has apparently decided to DMCA themselves, as they have removed their own hosted copies of their own free standard from their own website in response to me... providing a link to it? Perhaps there is some internal miscommunication regarding whether the CTA wants these standards to be publicly accessible or not. Just in case any CTA employees missed the memo, your organization decided to make your entire library of standards free to the public about a year ago. For people looking to access the CTA-861 standards, they can still be obtained from the CTA store (although you must first register an account and then "buy" the standard for $0.00). The benefits of this inconvenient process remain a mystery, but the CTA apparently feels it is very important to enforce this strange method of distributing free public documents.
I assume the CTA just really, really wants everyone to have to use their store interface to obtain the documents, and then download a copy of the document to read it instead of viewing a hosted version in the browser, for some inexplicable reason. I would suggest the CTA take lessons from the ITU, which directly hosts all their free standards documents (example). This system seems to work just fine for them, and it can work for you too!
