                  9




    This chapter describes those features of PDF that support embedding and playing
    multimedia content. It contains the following sections:

    • Section 9.1, “Multimedia” describes the comprehensive set of multimedia capa-
      bilities that were introduced in PDF 1.5.
    • Section 9.2, “Sounds,” and Section 9.3, “Movies,” describe features that have
      been supported since PDF 1.2.
    • Section 9.4, “Alternate Presentations,” describes a slideshow capability that was
      introduced in PDF 1.4.
    • Section 9.5, “3D Artwork,” describes the capability of embedding three-dimen-
      sional graphics in a document, introduced in PDF 1.6.


9.1 Multimedia

    PDF 1.5 introduces a comprehensive set of language constructs to enable the fol-
    lowing capabilities:

    • Arbitrary media types can be embedded in PDF files. (See implementation
      note 148 in Appendix H for a list of media types that are recommended for use
      with Acrobat 6.0 viewers).

    • Embedded media, as well as referenced media outside a PDF file, can be played
      with a variety of player software. (In some situations, the player software may
      be the viewer application itself.)
      Note: The term playing can be used with a wide variety of media, and is not re-
      stricted to audio or video. For example, it may be applied to static images such as
      JPEGs.
