メディア アクション フィードを提供する: JSON メディア アクション フィードを Google に提供すると、Google TV のおすすめや、Google 検索などの他の Google サーフェスを通じてコンテンツが見つかるようになります。提供するディープリンクを使用すると、ユーザーはコンテンツの再生に直接移動できるため、エンゲージメントを高めることができます。フィードでは、デバイス上の検索や、Google アシスタントの音声コマンドを使用したメディアの再生も可能です。
Google では、段階的に各プロバイダをこの機能に統合するために、同時に連携を行うプロバイダの数を制限しています。詳しくは、メディア アクションのドキュメントをご覧ください。
Watch Next を統合する: Watch Next を使用すると、ユーザーはアプリ内のコンテンツを再開できます。映画の途中でアプリを離れた場合や、テレビ シリーズの視聴中にアプリを離れた場合、Watch Next を使用して、そのコンテンツを Google TV のホーム画面に直接表示できます。ユーザーはタイルを選択して、アプリ内の再生に直接ディープリンクできます。なお、Google TV デバイスに表示するには、Watch Next の統合が品質認定を受けている必要があります。詳しくは、次のおすすめのドキュメントをご覧ください。
音声とエンゲージメント
アカウント リンクをサポートする: アカウント リンクにより、ユーザーの Google アカウントとアプリのアカウントをシームレスにリンクできるため、アプリの既存ユーザーと新規ユーザーのユーザー エクスペリエンスを合理化できます。アカウント リンクは、シームレスな購入プロセス、利用資格の同期、音声キャストなどの他の機能の前提条件です。
Android TV OS 向けに構築されたアプリは、新しい Google TV ブランドのデバイスを含む、TV エコシステムのすべてのデバイスで動作します。デバイスが Google TV の機能を提供しているかどうかを（分析などの目的で）確認するには、システム機能 com.google.android.feature.AMATI_EXPERIENCE を評価またはフィルタします。

To\nprovide the best user experience on Google TV, we recommend that you\napply the best practices in this guide.\n| **Note:** To ensure a great user experience, all TV apps must meet specific requirements for usability before they are available for TVs on Google Play. For more information, see [TV app quality](/docs/quality-guidelines/tv-app-quality).\n\nBaseline requirements\n---------------------\n\n- **Support Google Cast:** Google Cast lets you extend your Android, iOS, and Chrome apps to enable audio and video streaming to Android TVs as well as Chromecast devices and Assistant devices. For more information, see the [Google Cast\n documentation](https://developers.google.com/cast/docs/developers).\n- **Use media sessions:** media sessions provide a universal way of interacting with an audio or video player. When an app informs Android that it is playing media, playback controls can be delegated to the app. Integrating with the media session lets an app advertise media playback externally and receive playback commands from external sources. These sources can be physical buttons, such as the play button on a headset or TV remote control, or indirect commands, such as instructing \"pause\" to Google Assistant. The media session then delegates these commands to the app, which applies them to the media player where the commands originated. See [Using a media session](/guide/topics/media-apps/working-with-a-media-session) for more details.\n\nContent discovery across surfaces\n---------------------------------\n\n- **Offer a media actions feed:** when you provide a JSON media actions feed to Google,\n your content can be discovered through Google TV recommendations and\n other Google surfaces, such as Google Search. The deep links you provide let\n users jump directly into playback of your content to increase engagement. The\n feed also enables on-device search and the ability to play media using Google\n Assistant voice commands.\n\n Google is working with a limited number of\n providers at a time to integrate them into this feature. For more details,\n see the\n [Media Actions documentation](https://developers.google.com/actions/media).\n- **Integrate Watch Next:** Watch Next lets users re-engage with the content in your\n app. When users leave your app partway through a movie or with a TV series in\n progress, you can surface that content directly on the Google TV home screen\n using Watch Next. The user can select a tile to deep link directly\n into playback within your app. Note that a Watch Next integration must be\n certified for quality to show on Google TV devices. See the [Watch Next\n documentation](/training/tv/discovery/watch-next-add-programs) for more details.\n\nVoice and engagement\n--------------------\n\n- **Support account linking:** account linking provides seamless linking between a user's Google Account and your app's account to facilitate a streamlined user experience for your app's existing and new users. [Account\n linking](https://developers.google.com/identity/account-linking) is a prerequisite for other capabilities such as frictionless subscriptions, entitlement sync, and voice casting.\n- **Support entitlement sync:** if your media actions feed includes media with entitlement requirements---for example, a user needs to have a particular subscription to access content---you can support entitlement sync to declare which subscriptions a linked account has. See the [entitlements endpoint\n documentation](https://developers.google.com/actions/media/concepts/access-requirements#entitlements-endpoint) for more details.\n- **Offer voice casting:** voice casting lets your users initiate media playback on supported Cast devices through Google Assistant. You can enable this functionality by providing a [media actions](https://developers.google.com/actions/media) feed, supporting [account linking](https://developers.google.com/identity/account-linking/oauth-with-sign-in-linking?oauth=implicit), and creating a [Cast receiver](https://developers.google.com/cast/docs/developers).\n- **Enable Cast Connect:** with Cast Connect, your Android TV app can act as a Cast receiver. This lets you provide a richer experience and support interaction with the remote control. See the [Android TV Receiver Overview](https://developers.google.com/cast/docs/android_tv_receiver) for more details.\n\nUser acquisition\n----------------\n\n- **Integrate Google Play Billing:** use the Play Billing library to support in-app purchases and manage subscriptions across both mobile and TV. See the [billing\n documentation](/google/play/billing) for more details.\n- **Provide frictionless subscriptions:** by combining [streamlined account linking](https://developers.google.com/identity/account-linking/oauth-with-sign-in-linking?oauth=implicit), [Play Billing](/google/play/billing) with [real time developer notifications](/google/play/billing/getting-ready#configure-rtdn), and [silent sign-in](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInClient.html#silentSignIn%28%29), you can provide a seamless purchase experience for your users. Watch the [Frictionless Subscriptions video](https://www.youtube.com/watch?v=ARuf97ncE4w&list=PLWz5rJ2EKKc-Z8NeBXJkf1bzUVhx3fvh4&index=4) for more details.\n\nGoogle TV feature evaluation\n----------------------------\n\nAn app built for Android TV OS works for all the devices in the TV ecosystem,\nincluding new Google TV branded devices. To know whether a device\noffers the Google TV experience, for instance for analytics, you can\n[evaluate or\nfilter](/guide/topics/manifest/uses-feature-element#market-feature-filtering)\non the system feature `com.google.android.feature.AMATI_EXPERIENCE`."]]
