直播电视频道

借助直播电视频道集成，用户可以使用语音指令在支持 Google 助理的任何设备（例如 Google Home、Android、Android TV 或 Google TV 等）上观看和切换电视频道。

服务提供商可以使用 BroadcastService、CableOrSatelliteService、TelevisionChannel 和 Organization 标记对象在媒体操作 Feed 中提供频道的详细信息，以便 Google 支持以下用户查询：

“Hey Google，播放 ExampleTV。”
“Hey Google，调到 ExampleTV-HD。”
“Hey Google，切换到 7 频道。”
“Hey Google，ExampleTV-Drama。”

直播电视频道实体类型

直播电视频道集成要求媒体目录 Feed 中有 4 种实体类型（Organization、BroadcastService、CableOrSatelliteService 和 TelevisionChannel）。这些实体类型有助于回答以下问题：

电视服务提供商是谁？他们提供哪些服务？
上述各项服务中有哪些频道（也称为频道组）？

以下部分将深入探讨实体类型，并解答上述问题。

在阅读以下各部分时，请注意以下关系图：

代表电视服务提供商

电视服务提供商（也称为电视运营商）是向订阅者提供电视节目套装的组织。在大多数情况下，此人也是媒体目录 Feed 的创建者。这由 Organization 实体表示。只能向 Feed 中添加一个代表电视运营商的此类 Organization 实体。

例如，虚构的 IPTV 服务提供商“ExampleTV Digital”通过其名为“Digital Prime+”的服务，向美国用户群提供 180 个频道。

}

表示电视服务提供商提供的服务

CableOrSatelliteService 表示电视运营商提供的区域性有线电视、卫星或互联网电视服务。它通常与频道组相关联，并且会关联到电视运营商（由组织实体表示）。您可以向 Feed 中添加一个或多个 CableOrSatelliteService 实体，具体取决于电视运营商提供的服务数量。

在此示例中，我们使用一个 CableOrSatelliteService 实体来描述“Digital Prime+”创建覆盖美国的服务。请注意它是如何引用“ExampleTV Digital”的电视服务提供商（使用 provider 属性）。

  },
  "areaServed":[
    {
      "@type":"Country",
      "name": "US",
    }
  ]
}

代表电视服务提供商提供的频道

这些通道由 3 个实体一起表示：Organization、BroadcastService 和 TelevisionChannel。

BroadcastService 实体是核心实体，表示发行线性节目的电视频道。它链接到 Organization 和 TelevisionChannel 实体，并由一组 BroadcastEvent 实体引用，这些实体共同代表着节目指南（或频道时间表）。
- BroadcastService 实体还应具有明确定义的深层链接和访问要求。借助 BroadcastService 架构，您可以根据用户当前的设备位置（使用 eligibleRegion 和 ineligibleRegion 属性）限制对某个渠道的访问权限。如需了解详情，请参阅 Live TV 使用权用例。
Organization 实体表示制作和发行电视节目的频道。在大多数情况下，这是 BroadcastService 实体的副本，而在其他情况下，它可能代表 BroadcastService 所属的电视网络。BroadcastService 实体使用 broadcastAffiliateOf 属性引用 Organization 实体。了解这两种实体类型之间的关系至关重要。您可以在下面的了解组织与 BroadcastService 实体之间的关系部分了解详情。
TelevisionChannel 实体通过唯一标识符（例如频道号或字符串）及其在区域有线、卫星或互联网电视服务中的显示顺序（在提供商的媒体资源，例如网站或应用上）识别 BroadcastService，由 CableOrSatelliteService 实体表示。

TelevisionChannel、CableOrSatelliteService 和 Organization 实体共同构成了频道组的概念。

在我们的示例中，假设“ABC Movies”是“ExampleTV Digital”的电视服务提供商通过其“Digital Prime+”提供美国的这项服务此频道在合集中的频道号为 7，在 ExampleTV Digital 的 Android TV 应用中排在第 18 位。具体表示如下：

BroadcastService

一个 BroadcastService 实体，每个实体都代表相应频道（在本例中为两个 BroadcastService 实体分别对应虚构频道 ExampleTV-MovieChannel 和 ExampleTV-ComedyChannel）

 }

TelevisionChannel

每个 BroadcastService 有一个（或多个）TelevisionChannel 实体，该实体表示提供商（组织 - TVOperator）提供的 (CableOrSatelliteService) 服务中提供的频道编号（在本例中，TelevisionChannel 实体表示 ExampleTV 数字服务 IPTV 的 ExampleTV 电影节目在频道 7 上播放，ExampleTV 喜剧节目在频道 9 上播放）

  {

    }
  }

了解组织与 BroadcastService 实体之间的关系

BroadcastService 实体是代表电视频道的核心实体。尽管 Organization 实体是必需 Feed 实体，但其实际存在只是为了让提供方模拟下面介绍的三种例外情况用例。因此，除例外情况用例外，提供程序都应遵循以下要点。

经验法则有 3 个例外情况，即 Organization 和 BroadcastService 实体之间必须存在 1:N 关系。具体如下所述：

本地频道或联属频道
时移频道
在线播放质量存在差异的频道

本地频道或联属频道

例如，Fox 在美国西雅图有名为 KCPQ 的本地联属频道，在美国旧金山有 KTVU。KCPQ 可能会提供涵盖西雅图的本地新闻，而 KTVU 可能会提供专门针对旧金山用户群需求的节目。在大多数情况下，用户可能不知道该频道的本地名称，而只是认为该频道是 Fox。

在这种情况下，本地频道或联属频道应分别由各自的 BroadcastService 实体表示，所有这些实体都应与一个 Organization 实体相关联。当用户想切换到这些频道时，可以要求 Google 助理“切换到 Fox”或“切换到 KTVU/KCPQ”。Google 将根据用户的设备位置以及用户是否有权观看所请求的频道，切换到相应的本地频道。在前面的示例中，您需要创建一个代表 Fox 的组织实体，并将其关联到两个 BroadcastService 实体，每个实体分别代表一个本地关联公司 KCPQ 和 KTVU。

下面的另一个示例展示了应如何根据模型估算 ABC 频道及其本地联属频道：ABC

组织名称	BroadcastService 名称	婚恋状况
ABC	KAAL	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
ABC	KABC
ABC	KAEF
ABC	KAKE
ABC	KAMC
ABC	KAPP
ABC	KATC
ABC	KATN
ABC	KATU
ABC	KATV

我们再举一个例子。在这里，WXVT 和 WYOU 是本地 CBS 频道。CBS Sports Network 不是本地频道，并且独立于上述地方联属机构。

组织名称	BroadcastService 名称	婚恋状况
CBS	WXVT	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
CBS	WYOU	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
CBS Sports Network	CBS Sports Network 高清	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系

为了简单说明一下这一点，我们以 EPIX 和 EPIX 2 频道为例。这两类频道均面向全国提供，提供完全不同的节目内容，并非同一频道的不同版本，因此不被视为本地频道。

组织名称	BroadcastService 名称	婚恋状况
EPIX	EPIX	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系
第 2 集	第 2 集	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系

时移频道

在这种情况下，每个时移频道都应由其自己的 BroadcastService 实体表示，所有这些实体都应与一个 Organization 实体相关联。以下示例说明应如何对时移频道进行建模：

组织名称	BroadcastService 名称	婚恋状况
STARZ 加演	STARZ Encore West 购物中心	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
STARZ 加演	东方 STARZ 演唱会	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系

在线播放质量有差异的频道

例如，STARZ Encore Action HD 和 STARZ Encore Action SD 和 STARZ Encore Action SD 频道采用完全相同的节目 (EPG)，而直播质量只是两者之间的唯一区别。在这种情况下，每个视频质量流频道都应由其自己的 BroadcastService 实体表示，所有这些实体都应连接到一个 Organization 实体。

以下示例说明应如何根据流式传输质量差异的频道进行建模：

组织名称	BroadcastService 名称	婚恋状况
SBS	SBS	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
SBS	SBS HD	`Organization` 和 `BroadcastService` 实体之间的 1:N 关系

下面是一个复杂的用例示例，它将所有实际用例组合在一起：

组织名称	BroadcastService 名称	婚恋状况
Starz	STARZ 东部	由于时移频道，`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
Starz	STARZ 西区	由于时移频道，`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
STARZ Kids 和家庭	STARZ Kids 和家庭	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系
STARZ Encore 黑色	STARZ Encore 黑色	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系
STARZ Encore Clsic	STARZ 安可经典曲目	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系
STARZ 安可系列	STARZ 安可系列	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系
STARZ 加演悬疑片	STARZ 加演悬疑片	`Organization` 和 `BroadcastService` 实体之间的 1:1 关系
STARZ Encore 动作片	STARZ Encore 动作高清	由于流式传输质量差异，`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
STARZ Encore 动作片	STARZ 加演版（标清）	由于流式传输质量差异，`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
STARZ 加演	STARZ Encore West 购物中心	由于时移频道，`Organization` 和 `BroadcastService` 实体之间的 1:N 关系
STARZ 加演	东方 STARZ 演唱会	由于时移频道，`Organization` 和 `BroadcastService` 实体之间的 1:N 关系

Android TV 上的频道切换

与直播电视频道集成后，用户可以让 Google 使用语音指令切换频道。Google 使用自然语言处理 (NLP) 技术从用户查询中提取参数，并确定用户想要观看哪个频道。然后，Google 会通过以下方式之一处理渠道切换：

由 Google 执行 - Google 使用媒体操作 Feed 中提供的深层链接执行频道切换。Google 可通过 Feed 中的信息查找用户想要观看的频道的深层链接。然后，Google 会直接将用户引导至服务提供商的应用或平台上的内容。
由电视服务提供商执行 - Google 向服务提供商发送请求。Google 和服务提供商可以通过多种不同的方式协调频道切换任务。如需详细了解如何与 Google 的其他平台（例如 AndroidTV、Made by Google、Google 助理面向运营商的 Google 助理）集成，请与 Google 联系。

媒体操作 Feed 中所需信息的类型取决于服务提供商希望 Google 如何处理频道切换。

由 Google 履单

在此方法中，Google 会使用 BroadcastService 实体中提供的深层链接将用户直接转到服务提供商的应用或平台上的内容。用户可通过以下两种不同方式表明他们想要观看哪个频道：

按频道名称切换

当用户查询包含频道名称时（例如“Hey Google，播放 ExampleTV”），Google 会执行以下操作：ExampleTV

用户说“Hey Google，播放 ExampleTV”。ExampleTV
Google 将用户查询与 Google NLP 的通道切换 intent 进行匹配。
Google 会从用户查询中提取该参数（在本例中为 ExampleTV）。
Google 会使用渠道名称标识 BroadcastService。
Google 会从 BroadcastService 检索深层链接。
Google 使用深层链接发起新电视频道的播放。

按频道号切换

当用户查询包含频道号时（例如“Hey Google，切换到第 7 频道”），Google 会执行以下操作：

用户说“Hey Google，切换到 7 频道”。
Google 会将用户查询与频道切换 intent 进行匹配。
Google 会从用户查询中提取该参数（在本例中为 channel 7）。
Google 会根据用户的位置信息来识别区域性电视服务 (CableOrSatelliteService)。
Google 使用渠道号和 CableOrSatelliteService 标识相应的 TelevisionChannel.
Google 标识与 TelevisionChannel 相关联的 BroadcastService。
Google 会从 BroadcastService 检索深层链接。
Google 使用深层链接发起新电视频道的播放。

由电视服务提供商提供

当 Google 将控制权交给电视服务提供商以执行频道切换时，Google 会从用户查询中提取频道信息（频道 ID 或名称），并将这些信息作为参数添加到向服务提供商发出的请求中。

如果采用这种方法，可以选择在 BroadcastService 中提供深层链接和访问要求（请参阅由 TV 服务提供商完成的示例）。

由于此方法要求服务提供商与 Google 建立端到端通信，因此服务提供商还需要面向运营商的 Google 助理集成。如需了解详情，请与 Google 联系。
