Separate Delivery (CPRM Mandatory)</h2> <p>SD Separate Delivery (SD-SD) enables flexible distribution to manage a variety of content while protecting copyrights. In the SD-SD, the content key and content data can be treated separately. SD-SD supports the following distribution schemes.</p> <ul class="linklist"> <li>Writing data at kiosk terminals</li> <li>Pre-loaded content</li> <li>Download and recording</li> <li>Key download</li> </ul> <p>The SD memory card can be used as a key storage dongle, as well. Only keys are stored in the SD memory card. A user can play back content data in devices only when the SD memory card is inserted in the device. Users need to use CPRM compliant SD memory cards for saving the key information.</p> <p>SD-SD provides several content format profiles. Some profiles have compatibility with the corresponding SD Application, such as between SD-SD Audio and SD-Audio. SD-SD Audio content can be exported as content in SD-Audio format.</p> <h2>SD-SD Application Profile</h2> <table class="lineborder" width="100%" cellspacing="1" cellpadding="3"> <colgroup> <col width="20%"> <col width="80%"> </colgroup> <tbody> <tr class="odd"> <th class="left" style="FONT-WEIGHT: 800; TEXT-ALIGN: right">Audio</th> <td>Specifies audio content format, such as AAC<br /> Possible to export as SD-Audio format</td> </tr> <tr class="even" style="CLEAR: right"> <th class="left" style="FONT-WEIGHT: 800; TEXT-ALIGN: right">Video</th> <td>Specifies video content format, such as H.264<br /> Possible to export as SD-Video format</td> </tr> <tr class="odd"> <th class="left last" style="FONT-WEIGHT: 800; TEXT-ALIGN: right">eBook</th> <td>Specifies eBook content format combined with text, image, sound and video<br /> Standard open to other major eBook formats upon demand</td> </tr> </tbody> </table> <h3 class="mt30">Writing at kiosk terminals</h3> <p class="imagemargin"><img decoding="async" src="https://www.sdcard.org/cms/wp-content/uploads/2020/12/sd-sd-47-en.png" alt="Writing at kiosk terminals"></p> <h3>Pre-loaded SD Memory Card</h3> <p class="imagemargin"><img decoding="async" src="https://www.sdcard.org/cms/wp-content/uploads/2020/12/sd-sd-48-en.png" alt="Pre-loaded SD Memory Card"></p> <h3>Download and recording</h3> <p class="imagemargin"><img decoding="async" src="https://www.sdcard.org/cms/wp-content/uploads/2020/12/sd-sd-49-en.png" alt="Download and recording"></p> <h3>Key Download</h3> <p class="imagemargin"><img decoding="async" src="https://www.sdcard.org/cms/wp-content/uploads/2020/12/sd-sd-50-en.png" alt="Key Download"></p> <h3>Key storage dongle</h3> <p class="imagemargin"><img decoding="async" src="https://www.sdcard.org/cms/wp-content/uploads/2020/12/sd-sd-51-en.png" alt="Key storage dongle"></p> </div> </div> </section> <footer class="article-footer"> </footer> </article> </main> </div> </div> <footer class="footer" role="contentinfo" itemscope itemtype="http://schema.org/WPFooter"> <div id="inner-footer" class="wrap cf"> <nav role="navigation"> </nav> <div class="copy"> <p class="mt15 mb5"><span>SD and related marks and logos are trademarks of SD-3C LLC.</span></p> <p class="mb5">© 2000 - 2024 SD-3C LLC.
