電視直播頻道

電視直播頻道整合完成後,使用者就能在支援 Google 助理的任何裝置上,使用語音指令觀看及切換電視頻道,例如 Google Home、Android、Android TV 或 Google TV 等。

使用語音切換電視頻道
圖 1.透過語音切換電視頻道。

服務供應商可以使用 BroadcastServiceCableOrSatelliteServiceTelevisionChannelOrganization 標記物件,在媒體動作動態饋給中提供頻道詳細資料,讓 Google 支援下列使用者查詢:

  • 「Ok Google,播放 ExampleTV。」
  • 「Ok Google,播放 ExampleTV-HD。」
  • 「Ok Google,切換到頻道 7」。
  • 「Ok Google,ExampleTV-Drama。」

直播電視頻道實體類型

媒體目錄動態饋給中需要有 4 種實體類型 (OrganizationBroadcastServiceCableOrSatelliteServiceTelevisionChannel),才能整合直播電視頻道。這些實體類型有助於回答下列問題:

  • 電視服務供應商是哪一家?他們提供哪些服務?
  • 每項服務 (又稱為頻道首選頻道) 提供哪些管道組合?

以下章節會深入瞭解實體類型,並解答上述問題。

閱讀以下各節時,請記住以下關係圖:

代表電視服務供應商

電視服務供應商又稱為電視業者,是提供給訂閱者的整套電視節目。在大多數情況下,這也是媒體目錄動態饋給的建立者。這會以 Organization 實體表示。動態饋給中只應加入「一個」Organization實體,代表電視業者。

例如,虛構的 IPTV 服務供應商「ExampleTV Digital」在「Digital Prime+」服務中,向美國的使用者群開放 180 個頻道。

{
  "@context": ["http://schema.org", {"@language": "en"}],
  "@type":"Organization",
  "@id":"http://example.com/exampletv/digital",
  "name":"ExampleTV Digital",
  "sameAs": "https://en.wikipedia.org/wiki/exampletv_digital"
}

代表電視服務供應商提供的服務

CableOrSatelliteService 代表電視業者提供的區域性有線電視、衛星電視或網際網路電視服務。通常與頻道首選頻道相關聯,並會連結到電視業者 (以機構實體表示)。視電視業者提供的服務數量而定,你可以為動態饋給新增一或多個 CableOrSatelliteService 實體。

本例中,有一個用來描述「Digital Prime+」的 CableOrSatelliteService 實體建立涵蓋美國全國性的服務。請留意參照「ExampleTV Digital」使用 provider 屬性的電視服務供應商。

{
  "@context": ["http://schema.org", {"@language": "en"}],
  "@type":"CableOrSatelliteService",
  "@id":"http://example.com/example_iptv/us",
  "name":"Example TV Digital Prime Plus US Service",
  "provider": {
    "@type": "Organization",
    "@id": "http://example.com/exampletv/digital",
  },
  "areaServed":[
    {
      "@type":"Country",
      "name": "US",
    }
  ]
}

代表電視服務供應商提供的頻道

這些管道是由 3 個實體組成:OrganizationBroadcastServiceTelevisionChannel

  • BroadcastService 實體是核心實體,代表發布線性節目的電視頻道。會連結至 OrganizationTelevisionChannel 實體,並由 BroadcastEvent 實體組合參照,這些實體會同時代表節目規劃指南 (或頻道時間表)。

    • BroadcastService 實體也應另外定義明確的深層連結存取規定BroadcastService 結構定義可讓您根據使用者目前的裝置位置 (使用 eligibleRegionineligibleRegion 屬性),限制頻道的存取權。詳情請參閱「電視直播授權用途」。
  • Organization 實體代表製作及發布電視節目的頻道。在大多數情況下,這是 BroadcastService 實體的備用資源,而在其他情況下,它可能代表與 BroadcastService 相關聯的電視聯播網。BroadcastService 實體使用 broadcastAffiliateOf 屬性參照 Organization 實體。請務必瞭解這兩種實體類型之間的關聯性。詳情請參閱下方的「瞭解機構與 BroadcastService 實體之間的關係」一節。

  • TelevisionChannel 實體會透過專屬 ID (例如頻道號碼或字串) 來識別 BroadcastService,以及在區域有線電視、衛星或網路電視服務中,以 CableOrSatelliteService 實體表示的顯示順序 (在供應商的資源中,例如網站或應用程式)。

TelevisionChannelCableOrSatelliteServiceOrganization 實體會共同形成首選頻道的概念。

在這個範例中,假設「ABC Movies」是「ExampleTV Digital」的 180 個頻道電視服務供應商提供「數位 Prime+」成員的存取權這項服務在美國的提供。這個頻道在首選頻道中,第 7 個頻道編號在 18 歲,在 ExampleTV Digital 的 Android TV 應用程式中。如下所示:

 }

TelevisionChannel

供應商 (機構 - TVOperator) 提供的服務 (機構 - TVOperator) 服務中,每個 BroadcastService 的 TelevisionChannel 實體代表該實體提供的頻道號碼 (在本例中為 TelevisionChannel 實體在頻道 7 上提供 ExampleTV Movie 節目,以及 9 頻道 9 的 ExampleTV 節目節目)。

  {
    "@context": ["http://schema.org", {"@language": "en"}],
    "@type":"TelevisionChannel",
    "@id":"http://example.com/exampletv/extv-movie",
    "broadcastChannelId":"7",

      "@id":"https://www.example.com/exampletv/broadcast/movie"
    }
  }

瞭解機構和 BroadcastService 實體之間的關係

BroadcastService 實體是代表電視頻道的核心實體。雖然 Organization 實體是必要的動態饋給實體,但實際上,該實體只是為了讓供應商建立以下三種例外狀況用途的模型。因此,除了例外狀況,提供者應遵循以下重點。

根據經驗法則有 3 個例外狀況,這表示 OrganizationBroadcastService 實體之間必須有 1:N 的關係。詳細說明如下:

當地頻道或聯盟頻道

舉例來說,「Fox」美國西雅圖美國舊金山地區分別提供「KCPQ」和「KTVU」的本地聯盟頻道。KCPQ 可能會提供有關西雅圖的當地新聞,KTVU 可能會根據舊金山使用群體的需求提供專門的節目。在多數情況下,使用者可能不知道頻道的當地名稱,而是只辨識為「Fox」的頻道。

在這種情況下,本地或聯盟頻道應以各自的 BroadcastService 實體表示,且所有這些頻道都應連結至一個 Organization 實體。使用者想要切換到這些頻道時,可以要求 Google 助理選擇「切換至 Fox」即可。或「切換至 KTVU/KCPQ」。Google 會根據使用者裝置的所在位置,以及他們是否有權觀看要求的頻道,切換至適當的當地頻道。在先前的範例中,您會建立一個代表 Fox 的機構組織實體,並連結至兩個 BroadcastService 實體,每個實體分別代表一個本地關係企業 (KCPQKTVU)。

以下示範如何模擬「ABC」ABC頻道及其當地聯盟頻道:

ABCKAEF

我們再舉一個例子。WXVTWYOU 是本地的 CBS 頻道。CBS Sports Network 並非地方頻道,與前述當地聯盟無關。

第 2 集 第 2 集 OrganizationBroadcastService 實體之間的 1:1 關係

經過時間轉換的頻道

在這種情況下,每個經過調整的管道都應以自己的 BroadcastService 實體表示,而這些實體應連結至一個 Organization 實體。以下範例說明如何模擬經過時間調整的頻道:

機構名稱BroadcastService 名稱感情狀態
STARZ 安可STARZ Encore WestOrganizationBroadcastService 實體之間的 1:N 關係
STARZ 安可STARZ Encore East

串流品質差異的頻道

舉例來說,STARZ Encore Action HDSTARZ Encore Action SD 等頻道採用了完全相同的節目製作 (EPG),而兩者的串流品質則唯一的差異。在這種情況下,每個影片品質串流頻道都應以各自的 BroadcastService 實體表示,而所有頻道都應該連結至一個 Organization 實體。

以下範例說明應如何模擬有串流品質差異的頻道:

Android TV 上的頻道切換鈕

整合「電視直播」頻道後,使用者可透過語音指令要求 Google 切換頻道。Google 會使用自然語言處理 (NLP) 擷取使用者查詢中的參數,找出使用者想觀看的頻道,接著,Google 會透過下列其中一種方式處理頻道轉移作業:

  • 由 Google 完成 - Google 會使用媒體動作動態饋給中提供的深層連結執行頻道切換。這些資訊可讓 Google 查詢使用者想觀看的頻道深層連結。接著,Google 會將使用者直接導向服務供應商的應用程式或平台上的內容。
  • 電視服務供應商可出貨 - Google 向服務供應商傳送要求。Google 和服務供應商能以多種不同方式協調切換管道的工作。如需有關整合 Google 其他平台 (例如 AndroidTVMade by Google電信業者適用的 Google 助理) 的整合詳情,請與 Google 聯絡。

媒體動作動態饋給需要的資訊類型,取決於服務供應商希望 Google 處理頻道切換的方式。
