Configuring SDI Video Output</h2> </div> </div> </div> <p>Broadcast, film, and video post production and digital cinema applications can require Serial Digital (SDI) or High Definition Serial Digital (HD-SDI) video output. SDI/HD-SDI is a digital video interface used for the transmission of uncompressed video signals as well as packetized data. SDI is standardized in ITU-R BT.656 and SMPTE 259M while HD-SDI is standardized in SMPTE 292M. SMPTE 372M extends HD-SDI to define a dual-link configuration that uses a pair of SMPTE 292M links to provide a 2.970 Gbit/sec interface. SMPTE 424M extends the interface further to define a single 2.97 Gbit/sec serial data link.</p> <p>SDI and HD-SDI video output is provided through the use of the NVIDIA driver along with an NVIDIA SDI output daughter board. In addition to single- and dual-link SDI/HD-SDI digital video output, frame lock and genlock synchronization are provided in order to synchronize the outgoing video with an external source signal (see <a href="chapter-26.html" title= "Chapter 26. Configuring Frame Lock and Genlock">Chapter 26, <i>Configuring Frame Lock and Genlock</i></a> for details on these technologies). This section describes the setup and use of the SDI video output.</p> <h3>Hardware Setup</h3> <p>Before you begin, you should check that your hardware has been properly installed. If you are using the Quadro FX 4000SDI, the SDI/HD-SDI hardware is located on the dual-slot card itself, and after installing the card, no additional setup is necessary. If you are using the Quadro FX 4500/5500SDI or Quadro FX 4600/5600 SDI II, the following additional setup steps are required inorder to connect the SDI daughter card to the graphics card. These steps must be performed when the system is off.</p> <div class="orderedlist"> <ol type="1"> <li> <p>Insert the NVIDIA SDI Output card into any available expansion slot within six inches of the NVIDIA Quadro graphics card. Secure the card's bracket using the method provided by the chassis manufacturer (usually a thumb screw or an integrated latch).</p> </li> <li> <p>Connect one end of the 14-pin ribbon cable to the G-Sync connector on the NVIDIA Quadro graphics card, and the other end to the NVIDIA SDI output card.</p> </li> <li> <p>On Quadro FX 4500/5500SDI, connect the SMA-to-BNC cables by screwing the male SMA connectors onto the female SMA connectors on the NVIDIA SDI output card. On Quadro FX 4600/5600 SDI II, this step is not necessary: the SDI II has BNC connectors rather than SMA connectors.</p> </li> <li> <p>Connect the DVI-loopback connector by connecting one end of the DVI cable to the DVI connector on the NVIDIA SDI output card and the other end to the "north" DVI connector on the NVIDIA Quadro graphics card. The "north" DVI connector on the NVIDIA Quadro graphics card is the DVI connector that is the farthest from the graphics card PCI-E connection to the motherboard. The SDI output card will NOT function properly if this cable is connected to the "south" DVI connector.</p> </li> </ol> </div> <p>Once the above installation is complete, you may boot the system and configure the SDI video output using nvidia-settings. These instructions assume that you have already successfully installed the NVIDIA Linux Accelerated Graphics Driver. If you have not done so, see <a href="chapter-04.html" title= "Chapter 4. Installing the NVIDIA Driver">Chapter 4, <i>Installing the NVIDIA Driver</i></a> for details.</p> <h3>Clone Mode Configuration with <span><strong class= "command">nvidia-settings</strong></span></h3> <p>SDI video output is configured through the nvidia-settings utility. See the <code class="filename">nvidia-settings(1)</code> man page, and the nvidia-settings online help (click the "Help" button in the lower right corner of the interface for per-page help information).</p> <p>After the system has booted and X Windows has been started, run nvidia-settings as</p> <pre class="screen"> % nvidia-settings </pre> <p>When the NVIDIA X Server Settings page appears, follow the steps below to configure the SDI video output.</p> <div class="orderedlist"> <ol type="1"> <li> <p>Click on the <code class="computeroutput">Graphics to Video Out</code> tree item on the side menu. This will open the <code class="computeroutput">Graphics to Video Out</code> page.</p> </li> <li> <p>Go to the "Synchronization Options" subpage and choose a synchronization method. From the <code class="computeroutput">Sync Options</code> dropdown click the list arrow to the right and then click the method that you want to use to synchronize the SDI output.</p> <div class="informaltable"> <table summary="(no summary available)" border="0"> <colgroup> <col> <col></colgroup> <thead> <tr> <th>Sync Method</th> <th>Description</th> </tr> </thead> <tbody> <tr> <td>Free Running</td> <td>The SDI output will be synchronized with the timing chosen from the SDI signal format list.</td> </tr> <tr> <td>Genlock</td> <td>SDI output will be synchronized with the external sync signal.</td> </tr> <tr> <td>Frame Lock</td> <td>The SDI output will be synchronized with the timing chosen from the SDI signal format list. In this case, the list of available timings is limited to those timings that can be synchronized with the detected external sync signal.</td> </tr> </tbody> </table> </div> <p></p> <p>Note that on Quadro FX 4600/5600 SDI II, you must first choose the correct Sync Format before an incoming sync signal will be detected.</p> </li> <li> <p>From the top Graphics to Video Out page, choose the output video format that will control the video resolution, field rate, and SMPTE signaling standard for the outgoing video stream. From the <code class="computeroutput">Clone Mode</code> dropdown box, click the <code class="computeroutput">Video Format</code> arrow and then click the signal format that you would like to use. Note that only those resolutions that are smaller or equal to the desktop resolution will be available. Also, this list is pruned according to the sync option selected. If genlock synchronization is chosen, the output video format is automatically set to match the incoming video sync format and this drop down list will be grayed out preventing you from chosing another format. If frame lock synchronization has been selected, then only those modes that are compatible with the detected sync signal will be available.</p> </li> <li> <p>Choose the output data format from the <code class= "computeroutput">Output Data Format</code> dropdown list.</p> </li> <li> <p>Click the <code class="computeroutput">Enable SDI Output</code> button to enable video output using the settings above. The status of the SDI output can be verified by examining the LED indicators in the <code class="computeroutput">Graphics to SDI property</code> page banner.</p> </li> <li> <p>To subsequently stop SDI output, simply click on the button that now says <code class="computeroutput">Disable SDI Output</code>.</p> </li> <li> <p>In order to change any of the SDI output parameters such as the Output Video Format, Output Data Format as well as the Synchronization Delay, it is necessary to first disable the SDI output.</p> </li> </ol> </div> <p></p> <h3>Configuration for TwinView or as a Separate X Screen</h3> <p>SDI video output can be configured through the nvidia-settings X Server Display Configuration page, for use in TwinView or as a separate X screen. The SDI video output can be configured as if it were a digital flat panel, choosing the resolution, refresh rate, and position within the desktop.</p> <p>Similarly, the SDI video output can be configured for use in TwinView or as a separate X screen through the X configuration file. The supported SDI video output modes can be requested by name anywhere a mode name can be used in the X configuration file (either in the "Modes" line, or in the "MetaModes" option). E.g.,</p> <pre class="screen"> Option "MetaModes" "CRT-0:nvidia-auto-select, DFP-1:1280x720_60.00_smpte296" </pre> <p>The mode names are reported in the nvidia-settings Display Configuration page when in advanced mode.</p> <p>Note that SDI "Clone Mode" as configured through the Graphics to Video Out page in nvidia-settings is mutually exclusive with using the SDI video output in TwinView or as a separate X screen.</p> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href= "chapter-26.html">Prev</a> </td> <td width="20%" align="center"><a accesskey="u" href= "part-01.html">Up</a></td> <td width="40%" align="right"> <a accesskey="n" href= "chapter-28.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top"> Chapter 26.
