For IEC 61937-X and HDMI, no need.

Some "nice-to-have" things would be an explanation for
dtshd_start_code[10] and an explanation of the MAT encapsulation (the
latter is probably in "Technical Bulletin - Dolby TrueHD Transmission
over the HDMI Interface"), which are AFAIK not described in IEC 61937-X
or HDMI specs.

Or the DTS-HD spec so that someone (not me) can implement a decoder in
ffmpeg ;)

My interest doesn't really extend beyond what my receiver supports, and
these were it.
