Question

在这方面我很困惑。我将Youtube Video从我的Android手机（使用名为AllConnect的控制器应用程序）传输到我的电视（渲染器）。在播放过程中，我可以看到应用程序上的进度条正在更新，我可以在时间内查找。直到这里，我明白了一切;我的手机发现了一个DLNA渲染器（电视）并正在“推送”内容。

当我也能够使用我的电视遥控器，通过按下背面和电视机来寻找内容时，事情开始变得混乱。前进按钮，我猜想要寻找+ -10秒。这个流程如何工作？当应用程序的进度条相应移动时，应用程序也会知道电视遥控器执行的搜索。

以下是我的电视上的规格：

Answer 1

实际上，在DLNA 1.0中，只引入了DMP(Digital Media Player)和DMS。 DMP充当播放器和控制器，因此该模式众所周知为2-box-pull。在DLNA 1.5中，DMC(Digital Media Controller)被分开，现在DMC控制DMR(Digital Media Renderer)呈现，此模式称为3-box-push

DMR可以控制当前媒体（可能是歌曲或播放列表），例如stop，seek等等，但是在任何更改后，{ {1}}会DMR发送给notification，DMC会更新播放状态。

更详细地说，按下DMC按钮后，电视会将状态从seek更改为PLAYING，当TRANSITIONING完成后，请更改回seek。同时，当PLAYING从电视获得DMC时，它会notification与电视同步位置。

DLNA Media Renderer也可以充当控制器吗？
