A/57B defines the semantics for how the individual programs are
labeled.  It ensures that each program gets a unique identifier which
can be used inside of PSIP to do associations across things like the
EIT table, the RRT, etc.

A/57B doesn't really say anything other providing a uniform
representation for the internal program identifers.  And it has no
actual bearing on indicating when a program starts or ends.

It's the same sort of thing that says you should always name the
filenames for your MP3 collection with the format

If you want to see how the identifiers are actually used, you would be
well advised to read A/63c instead.
