AppleTVアプリにFairPlay保護を追加する

概要

TVOS 用ネイティブ SDK は、FairPlay ストリーミングで HLS を使用したデジタル著作権管理 (DRM) 保護をサポートします。アカウントが DRM 対応で動的配信用に構成されている場合、動画は取り込むときに自動的に DRM 用にパッケージ化されます。

Fairplay で保護された動画のサポートは Brightcove Native SDK のコアフレームワークに統合されているため、アプリケーション証明書を読み込む必要はありません。詳細については、ネイティブプレーヤーの SDK を使用したコンテンツセキュリティ (DRM) ドキュメントを参照してください。

コードサンプル

Apple TV アプリに FairPlay コンテンツ保護を追加するには、次の手順に従います。

1. Apple TV の基本的なサンプルアプリから始めます。
2. アプリに FairPlay ライセンスコードを追加します。これは、基本的な FairPlay サンプルに記載されています。

ViewController.swift ファイルのコードは、次のようになります。
