EIT-3. For each virtual channel an extended channel name descriptor is present. For each event an
extended text message is available. Regarding
the Rating Region Table, suppose that a different
rating region than that given in the example of Annex D Section D.4.4 is used,
and it is defined
with six dimensions and five values per dimension. The example assumes this system and that a
typical content advisory uses two of the six dimensions. No Channel ETTs are used.
Based on these
assumptions, typical sizes for every PSIP table can be calculated. The
results
are listed in Table E9 and Table E10.
