                          TABLE 9.5 Entries in a minimum screen size dictionary
KEY       TYPE            VALUE

Type      name            (Optional) The type of PDF object that this dictionary describes; if present, must be
                          MinScreenSize for a rendition object.

V         array           (Required) An array containing two non-negative integers. The width and height (in
                          pixels) of the monitor specified by M must be greater than or equal to the values of
                          the first and second integers in the array, respectively, in order for this object to be
                          viable.

M         integer         (Optional) A monitor specifier (see Table 9.28) that specifies which monitor the val-
                          ue of V should be tested against. If the value is unrecognized, the object is not viable.
                          Default value: 0.


       Media Renditions

       Table 9.6 lists the entries in a media rendition dictionary. Its entries specify what
       media should be played (C), how (P), and where (SP) it should be played. A media
       rendition object is viable if and only if the objects referenced by its C, P, and SP
       entries are viable.

       C can be omitted only in cases where a referenced player takes no meaningful in-
       put. This requires that P is present and that its referenced media play parameters
       dictionary (see Table 9.14) contains a PL entry, whose referenced media players
       dictionary (see “Media Players Dictionary” on page 777) has a non-empty MU ar-
       ray or a non-empty A array.

                       TABLE 9.6 Additional entries in a media rendition dictionary
KEY       TYPE            VALUE

C         dictionary      (Optional) A media clip dictionary (see Section 9.1.3, “Media Clip Objects”) that
                          specifies what should be played when the media rendition object is played.

P         dictionary      (Required if C is not present, otherwise optional) A media play parameters dictionary
                          (see Section 9.1.4, “Media Play Parameters”) that specifies how the media rendition
                          object should be played.
                          Default value: a media play parameters dictionary whose entries (see Table 9.14) all
                          contain their default values.
