       SECTION 9.1                                                                    Multimedia



KEY      TYPE         VALUE

D        dictionary   (Optional) A dictionary (see Table 9.4) specifying the minimum bit depth required
                      in order for this object to be viable. Equivalent to SMIL’s systemScreenDepth at-
                      tribute.

Z        dictionary   (Optional) A dictionary (see Table 9.5) specifying the minimum screen size re-
                      quired in order for this object to be viable. Equivalent to SMIL’s systemScreenSize at-
                      tribute.

V        array        (Optional) An array of software identifier objects (see “Software Identifier Dictio-
                      nary” on page 779). If this entry is present and non-empty, the viewer application
                      must be identified by one or more of the objects in the array in order for this object
                      to be viable.

P        array        (Optional) An array containing one or two name objects specifying a minimum and
                      optionally a maximum PDF language version, in the same format as the Version en-
                      try in the document catalog (see Table 3.25). If this entry is present and non-empty,
                      the version of multimedia constructs fully supported by the viewer application must
                      be within the specified range in order for this object to be viable.

L        array        (Optional) An array of language identifiers (see “Language Identifiers” on page
                      937). If this entry is present and non-empty, the language in which the viewer appli-
                      cation is running must exactly match a language identifier, or consist only of a pri-
                      mary code that matches the primary code of an identifier, in order for this object to
                      be viable. Equivalent to SMIL’s systemLanguage attribute.



                      TABLE 9.4 Entries in a minimum bit depth dictionary
KEY      TYPE         VALUE

Type     name         (Optional) The type of PDF object that this dictionary describes; if present, must be
                      MinBitDepth for a minimum bit depth dictionary.

V        integer      (Required) A positive integer (0 or greater) specifying the minimum screen depth
                      (in bits) of the monitor for the rendition to be viable. A negative value is not al-
                      lowed.

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.
