注釈

PlayToSourceRequest クラスは、Play To ターゲットにストリーミングするソース メディアに対するユーザー要求を表します。 SourceRequested イベント中にアプリケーションから Play To にメディアを渡すには、PlayToSourceRequestedEventArgs クラスの SourceRequest プロパティを使用します。

ストリーミングするメディア要素を取得する非同期呼び出しを行う場合は、 GetDeferral メソッドを使用して遅延を作成できます。 Play To は、遅延を完了としてマークするまでメディア要素を指定するのを待ちます。

アプリケーションで Play To を使用する方法の例については、「 PlayReady DRM」を参照してください。
