要約：
このコード群は、ウェブサイトで動画再生と字幕表示を高度に制御するシステムを構築しています。
主な機能は以下の通りです。
1.  **動画プレーヤーとカスタム字幕:** HTML5の`<video>`タグを中心に、独自のCSSとJavaScriptでカスタマイズされた字幕オーバーレイ（`#scSubtitleOverlay`）を実装。フルスクリーン、ピクチャーインピクチャー（PiP）、AirPlayなどの特定の再生モードでは、自動的にネイティブ字幕表示に切り替わり、字幕の二重表示を防ぎます。
2.  **字幕リストとの連携:** 動画の再生時間に同期して、別途提供される字幕リスト（タイムスタンプ付き）内の該当箇所を自動でハイライトし、座標計算に基づいてスムーズにスクロールさせます。リスト内のタイムスタンプをクリックすると動画がその時点にジャンプ再生されます。
3.  **動画保護と利便性向上:** 動画コンテンツの右クリックによる保存やダウンロードを禁止し、画面遷移時に再生中のメディアを自動で一時停止させる機能を提供します。
4.  **WordPress連携（`dr52emd.php`）:** WordPressテンプレートとして機能し、URLの動画IDを元に、Googleドライブなどから動画ファイル、ポスター画像、字幕ファイル、字幕リスト、説明文などの情報を動的に取得・表示します。これにより、動画コンテンツを柔軟に埋め込んだり、単体ページとして公開したりできます。
