SMPTE doesn't have the rights to much of anything that doesn't start with SMPTE. HD-SDI is a marketing buzz word, unless it references the relevant spec. it's not worth the time it takes you to read it.

Recent SMPTE specs are not much better. The recent specs on MXF files are a joke. Pages and pages describing 10 different ways to do the same thing. Each of which can be reasonably inferred to mean several different things. Without an official testing and approval body, SMPTE specs have become worthless.

I have a recent situation where a piece of equipment puts out a purported HD-SDI signal yet the signal does not conform to SMPTE 292M. The manufacturer does not claim to be SMPTE 292M compliant. I would argue that to say it is an HD-SDI signal, it should conform to the specification that defines that term. But I don't think SMPTE owns the term and therefore it could be used however anyone wants to.

What do you all think?
