+<h1>External Output Manager (EOM)</h1>
+ <p>External Output Manager(EOM) is a module to control external output devices.</p>
+ <p>Until Tizen 2.3, Devicemgr(private module) is used for external output. But Devicemgr has some problems.</p>
+ <p> - Devicemgr problems</p>
+ <p> 1. Cannot know video-only mode start and stop.</p>
+ <p> 2. Doesn't have method to notify to application about external output informations.</p>
+ <p> 3. Application cannot display specific images to external output.)</p>
+ <p>So module for external output is replaced to EOM from Tizen 2.4. EOM fixes devicemgr's problems and manages all convergence scenarios of external output.</p>
+ <p>EOM is a module of enlightenment. And EOM has X and Walyland backend.</p>
+
+ <h2 id="mode" name="mode">Mode</h2>
+ <p>EOM has two modes. One is Mirror mode, the other is Presentation mode.</p>
+ <pre class="prettyprint">
+ <p class="figure">Figure: EOM mode</p>
+ <p style="text-align:center;"><img alt="Window layers" src="../../images/eom_mode.png" /></p>
+ </pre>
+ <P>Mirror mode is default mode. So if any application doesn't set presentation mode, Mirror mode will work by EOM module when external output device is connected.</P>
+ <P>Presentation mode can be set by application. If application wants to display it's own image or video to external output device, application must use presentation mode.</P>
+
+ <h2 id="attribute" name="attribute">Attribute for Presentation Mode</h2>
+ <p>Applications have to use EOM attributes to set presentation mode.</p>
+ <p>There are three priorities of EOM attribute. The meaning of set attribute is the application wants to display a window with fullscreen size on the external output. </p>
