+ *
+ * The client device may have MLB attached INIC OS81110 or USB attached INIC OS81118. \n
+ * All components where written for and tested for the FreeScale i.MX6q platform. \n
+ *
+ * \subsection step1 Step 1: Execute Server Application
+ *
+ * Login to the server target device. \n
+ * Switch to the directory, where you have copied all outputs of the previous steps. \n
+ * Make sure, that all devices are up and running and the MOST bus is well connected. \n
+ * Start the application. \n
+ * Enter:
+ * \code sudo ./VideoOnDemand config.xml \endcode
+ *
+ * After a while, you should see the main menu, with available connections: \n
+ * Display Output: \n
+ * \code

+ * \endcode
+ *
+ * At this point you should be able to connect with either the native C++ application or the Android HMI app.<br/>
+ * Make sure, you set the IP address correct on all devices.
+ *
+ * - In order to check if the streaming is correctly working, enable the the statistics printing.
+ * - Enter "p" and press Enter key.
+ *
+ * Display Output:
+ * \code
+ * ==============Statistic Start==============

+ * Overall sent performance of all streams: 134511 (kBit/s)
+ * ===============Statistic End===============
+ * \endcode
+ * - If everything is okay, the sent and read values are not zero. They may be different, as the Transport Stream file usually contains
+ * stuffing and control informations, which will not be sent over the MOST network.
+ * - The error values must be zero.
+ *
+ *
+ * \subsection step2 Step 2: Retrieve the isochronous stream on non Android clients
+ *
+ * If you are not using the Android App, login in to the client devices.\n
+ * \note Make sure you performed step
+ * - Step 1: Load Linux driver on target
+ * - Step 2: Enable Ethernet communication on MOST
+ * - Step 3: Execute the native C++ VideoOnDemand Client sample application
+ *
+ *
+ *
+ * In order to dump the received data to disk, enter:
+ * \code
+ * dd if=/dev/mdev0-ep0a of=myCapturedVideo.ts bs=7520
+ * \endcode
+ * \note Adapt the name of the character device, as listed by the VideoOnDemand sample application.
+ *
+ * You can also use the dev2udp helper tool, which is stored in the SlimCamera example folder.
