智慧型住宅電視指南

action.devices.types.TV - 電視裝置結合了調諧器、螢幕和音量喇叭,用於觀看及聆聽媒體。例如智慧型電視裝置。

此類型表示裝置會取得「電視」圖示和一些相關的同義詞和別名。

裝置功能

請參閱對應的特徵說明文件,瞭解實作詳情,例如瞭解服務支援的屬性和狀態,以及如何建構 EXECUTE 和 QUERY 回應。

必要特徵

您需要這些 traits 和指令 (如果裝置適用的話)。如果您的裝置不支援這些特徵,請在 QUERY 或 EXECUTE 回應中輸入 functionNotSupported 的錯誤代碼。詳情請參閱「錯誤與例外狀況」一節。

特徵 指令
action.devices.traits.AppSelector
  • action.devices.commands.appSelect
action.devices.traits.InputSelector
  • action.devices.commands.setInput
action.devices.traits.MediaState
  • 不適用
action.devices.traits.OnOff
  • action.devices.commands.OnOff
action.devices.traits.TransportControl
  • action.devices.commands.mediaClosedCaptioningOff
  • action.devices.commands.mediaClosedCaptioningOn
  • action.devices.commands.mediaNext
  • action.devices.commands.mediaPause
