name
array
(Optional)
The type of PDF object that this dictionary describes; if present, must be
MediaPlayers
for a media players dictionary.
(Optional)
An array of media player info objects (see Table 9.26) that specify a set of
players, one of which
must
be used in playing the associated media object.
Note:
Any players specified in
NU
are effectively removed from
MU
. (For example, if
MU
specifies versions 1 through 5 of a player and
NU
specifies versions 1 and 2 of the
same player,
MU
is effectively versions 3 through 5.)
MU
A
array
(Optional)
An array of media player info objects (see Table 9.26) that specify a set of
players, any of which
may
be used in playing the associated media object. If
MU
is
also present and non-empty,
A
is ignored.
(Optional)
An array of media player info objects (see Table 9.26) that specify a set of
players that
must not
be used in playing the associated media object (even if they are
also specified in
MU
).
NU
array
The
MU
,
A
, and
NU
entries each specify one or more media player info objects.
(An empty array is treated as if it is not present.) The media player info objects
are allowed to specify overlapping player ranges (for example,
MU
could contain a
media player info dictionary describing versions 1 to 10 of Player X and another
describing versions 3 through 5 of Player X).
