It seems to me that these are no longer glossary entries — or, only the first line of each is a
glossary entry. ...
Each entry is just one sentence, so I guess you don't like the sentence
spanning multiple lines (?)
The sentence is a statement followed by a list of metadata that distinguishes the subject... so that
people can determine whether a particular video is a d-NTSC video or not a d-NTSC video for example.
The main distinguishing feature is 'progressive_sequence' = 0 & 'progressive_frame' = 0 of course.
The others narrow the scope to just a single species of video.
If a glossary entry requires explanation, then it's a fail. What fails? I guess I didn't anticipate
such a total-failure mode.
Do you have any suggestions? Should I just forget this glossary idea?
... The rest seems to be a description of a data structure or representation. The entry
doesn't say to what format or specification the representation applies. To an MPEG-2 video? To a the
ISO file corresponding to a DVD?
