  <title>语音和视频支持</title>

  <p>您的联系人也在使用支持语音和视频会话的程序时，您才可以和他们进行语音、视频会话。如果您的联系人可以进行语音或视频会话，您将在联系人列表中他们的姓名旁看到下列图标：</p>

  <table frame="all" rules="cols rowgroups" shade="rows">
    <thead>
      <tr>
        <td>
          <p>图标</p>
        </td>
        <td>
          <p>描述</p>
        </td>
      </tr>
    </thead>
    <tbody>
    <tr>
      <td>
        <p>
          <media type="image" mime="image/png" src="figures/audio-input-microphone.png">
            Icon for audio conversation
          </media>
        </p>
      </td>
      <td>
        <p>联系人可以进行语音聊天。</p>
      </td>
    </tr>
    <tr>
      <td>
        <p>
          <media type="image" mime="image/png" src="figures/camera-web.png">
            Icon for video conversation
          </media>
        </p>
      </td>
      <td>
        <p>联系人可以进行视频聊天。</p>
      </td>
    </tr>
    </tbody>
  </table>
  
  <note>
    <p>要进行语音聊天，您需要有一块声卡，且您的操作系统必需支持它，还需要一个能正常工作的麦克风。</p>
    <p>要进行视频聊天，您需要操作系统支持的摄像头，及可以正常工作的麦克风。</p>

  <title>支持的账户类型</title>

  <p>只有一些特定类型的账户支持语音或视频聊天。下表列出了每种类型的账户的语音、视频支持情况。</p>

  <note>
    <p>账户类型是由插件提供的。您的系统上不一定有以下列出的全部类型，也可能有一些类型没有在下面列出。插件的升级可能使下表中不支持语音或视频的账户类型获得支持。</p>

    <p>I'd like to do tables like this using nothing for No and ✔ for Yes, but
    we need to look at the accessibility impact.  I've
    <link href="http://mail.gnome.org/archives/gnome-doc-list/2009-September/msg00006.html">asked
    the accessibility team</link> for input.</p>

    <p>There's recent work on telepathy-butterfly and papyon to support
    audio and video for MSN.  It might be released in time for 2.28, but
    since it doesn't follow the Gnome release schedule, I can't be sure.
    If it looks like it's going to ship, let's mark it Yes.</p>
