[Users] Adding DRM (Digital Rights Management) to smil MMS

Mon, 25 Aug 2008 05:53:33 -0700 

Hi Guys.
I have question about adding the DRM to the smil file content.

I am trying to add the DRM to the smil file content (images, audio, video),
I have searched in the mailing list and I got this thread

http://www.mail-archive.com/[email protected]/msg01173.html

*and the following is the smil file:*

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE smil PUBLIC "-//W3C//DTD SMIL 1.0//EN" "
http://www.w3.org/TR/REC-smil/SMIL10.dtd";>

<smil xmlns="http://www.w3.org/TR/REC-smil";>
  <head>
    <meta
          name="title"
          content="Test Smil MMS with DRM"/>
    <meta
          name="author"
          content="Author"/>
    <meta
          name="copyright"
          content="Copyright"/>
    <layout
            type="text/smil-basic-layout">
      <root-layout
                   id="rootLayout"
                   width="176"
                   height="208"/>
      <region
              id="image_reg"
              background-color="white"
              left="9"
              top="9"
              width="163"
              height="192"
              fit="fill"/>
      <region
              id="text_reg"
              left="18"
              top="78"
              width="144"
              height="48"/>
    </layout>
  </head>
  <body
        id="body">
    <seq>
      <img
           dur="3s"
           src="http://webserver/serving_files.php?file=img_1.jpg";
           region="image_reg"
           id="img_1"
           begin="0ms"/>
      <text
              dur="4s"
            src="http://webserver/text_file.txt";
            region="text_reg"
            id="text_1"
            begin="0ms"/>
      <img
           dur="4s"
           src="http://webserver/serving_files.php?file=img_2.jpg";
           region="image_reg"
           id="img_2"
           begin="0ms"/>
    </seq>
  </body>
</smil>

And I added the DRM Headers to the images through such script.

Is this the only way to add the DRM to the smil MMS?
Is there anybody used this way and success?
Is there any tutorial or manual to explain adding the DRM to a smil MMS?

Regards.
