电视网关、电视云、视频平台及分发系统
本申请要求在2020年10月23日提交日本专利局、申请号为2020-178454、发明名称为“电视网关”的日本专利申请的优先权，以及在2020年12月23日提交日本专利局、申请号为2020-214326、发明名称为“电视网关、电视云、视频平台以及分发系统”的日本专利申请的优先权，以及在2021年1月19日提交日本专利局、申请号为2021-006467、发明名称为“电视接收机及电视系统”的日本专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电视网关、电视云、视频平台及分发系统。
背景技术
近年来，由于网络的进化，实施很多动态图像分发服务。特别地，大型、大画面的电视接收机不仅如现在那样接收广播，还与网络连接，对被分发来的动态图像进行播放，从而能够以更高画质欣赏具有现场感的影像。这通过网络的高速化、电视接收机的处理性能的提高能够实现，今后考虑通过电视接收机来显示、操作由网络提供的各种内容的机会进一步增加。
动态图像分发服务正在高度化，不仅简单的动态图像收看，还从动态图像内容向EC(电子商务交易)网站引导来购入商品、通过动态图像来详细地确认因特网上的Web信息(例如新闻、票务信息等)等所谓的将动态图像与Web信息连结的交互式的服务正在展开。
在以上的各种状况中，家庭中能够简单使用的电视接收机成为将由网络提供的动态图像、Web网站的信息、EC服务等提供给用户的手段在今后的网络化进行中，成为非常重要的课题。
另外，由于网络的进化，动态图像分发服务被较多实施。此外，在该动态图像分发服务中，不仅简单的动态图像收看，从动态图像内容向EC(电子商务交易)网站引导并购入商品，根据因特网上的Web信息(例如新闻、票务信息等)通过动态图像来确认详细等所谓的将动态图像与Web信息连结的交互式的服务正在展开。
此外，通过各种CSP(Contents Service Provider，内容服务提供商)来提供动态图像分发服务。用户通过与各CSP签订合同，能够进行该CSP提供的动态图像的收看。在签订合同时，从各CSP发布用于识别用户的ID、密码。
然而，在通过电视接收机来收看各CSP分发的动态图像的情况下，以往，用户通过基于遥控器的操作来进行ID、密码的输入。电视接收机的遥控器通常是具备使焦点上下左右移动的方向键、用于输入数字的数字键等的程度，不是例如PC(Personal Computer，个人计算机)所具备的键盘那样文字输入自如的设备。因此，ID、密码的输入操作成为用户较大的负担，妨碍轻松的收看。
此外，通过视频平台与Web网站协作，从而实施这样的高级的服务，因此，难以用不同的视频平台和不同的功能、性能的电视接收机来通用地提供这样的联动服务。然而，在设置作为服务器的电视网关的情况下，例如在播放线性频道(Linear channel)的内容的情况下，因为广播时间是确定的，所以电视接收机对作为服务器的电视网关的访问会集中。因此，关于作为服务器的电视网关，需要与来自电视接收机的访问的集中峰值(peak)匹 配地进行设计，成本变高。

发明内容
由于网络的进化，相比于以前更容易实现动态图像分发服务。但是，接收电视接收机中的网络动态图像分发服务中存在各种课题，并未达到广播那样的接收普及。进一步地，当前，在PC等的信息终端中，通过被分发的动态图像和Web内容的联动，实施更加高度的网络服务，但在目前的电视接收机中，难以实现这样的联动服务。
相对于地面波的广播依据统一的标准来广播动态图像内容，基于网络的动态图像内容通过多个分发方式而被分发。因此，为了选择接收从分发特定的影像的视频平台分发的动态图像内容，需要在接收机侧装备特别的功能。此外，为了接收向电视广播接收机分发的动态图像内容，对电视接收机要求与网络连接的功能、对接收的动态图像内容进行播放的性能。
根据电视接收机侧的功能、性能，存在能够接收的分发动态图像内容、不能接收的分发动态图像内容。因此，相关技术中的实现动态图像分发服务的视频平台和接收终端通过在各自搭载独自的分发技术而实现。若从视频平台进行，需要分别对应多个不同性能、功能的接收终端，若从接收终端进行，需要分别对应多个不同分发方式的视频平台。此外，在进行动态图像内容的选择时也存在各种方法，不能提供一贯的节目选择方式，给用户带来混乱。这种状况不仅妨碍视频分发的普及，从用户方便性的角度来看也是较大的课题。
另一方面，在将动态图像内容与Web内容相互链接，交互地进行服务时，电视接收机由于是基于遥控器的操作，因此相比于PC等信息终端具有的键盘、鼠标等的输入功能极其缺乏操作性，用户难以方便地进行操作并接受高度的服务。另外，通过视频平台与Web网站进行协作，实施这种高度的服务，因此难以通过不同视频平台和不同功能或性能的电视接收机共同地提供这种联动服务。
图19中表示相关技术中的影像分发系统的结构图。图18中，CSP(内容服务提供商)101～108提供动态图像内容。动态图像内容分别向视频平台1611～1613输入。视频平台1611～1613将动态图像流向电视接收机141～150送出。由于各个视频平台的分发方式存在不同，因此各个动态图像流仅被有限的电视接收机接收。在该例中，视频平台1611能够通过电视接收机141～143来接收，视频平台1612能够通过电视接收机144～147来接收，视频平台1613能够通过电视接收机148～150来接收，难以向不同功能的电视接收机广泛共通地分发影像内容。此外，在将连接于视频平台1613的Web网站1601和由视频平台1613输出的动态图像联动进行服务的情况下，在通常的电视接收机的遥控器中，上下左右、数字按钮等中功能受限，对于用户的操作成为较大的负担。
使用图20，对由相关技术中的影像分发系统选择影像内容的动作进行说明。例如，图19中的电视接收机144～147从视频平台1612和1613这两者进行接收，因此用户如1701所示，先从平台选择画面1701，通过视频平台按钮1702、视频平台按钮1703进行选择。各个按钮由各个视频平台提供的视频平台选择原始数据1712、1722在电视接收机侧构成。 若按压任意的按钮，则进入内容选择画面1710，通过按压内容1711～1716的按钮来选择内容。这些按钮由从视频平台提供的内容原始数据1723生成。这种选择操作被电视遥控器1731实施。
进一步地，在选择了内容之后，动态图像内容与Web内容联动的情况下，例如，动态图像内容1741与Web内容1742被同时显示的情况下，需要更加复杂的动作，在电视遥控器1731中，用户的操作负担变大。因此，内容的表现产生限制。
此外，视频命令VOD能够在用户终端与VOD分发服务器之间进行利用的确认并收看视频内容。该情况下的节目表是VOD单独，成为与广播波、线性分发的视频内容的节目表不同的处理。
用于解决问题的手段是，提供一种电视网关，被配置于视频平台与电视之间，进行用于将来自该视频平台的动态图像内容提供给该电视的连接，其中，
电视网关接收视频点播令牌请求，该视频点播令牌请求附有：被配置于电视与电视网关之间的电视云发送的来自电视的用于识别视频平台的ID、用于识别作为收看对象的动态图像内容的ID、以及用于同时识别电视云的ID；
电视网关向视频平台发送：用于同时识别移动终端的用户和视频平台的ID(以下CT-ID)、以及用于识别作为收看对象的动态图像内容的ID(以下MA-ID)；
视频平台在具备基于CT-ID和MA-ID而能够收看VOD的条件下，接收包含CT-ID和MA-ID的视频点播令牌；
电视网关基于从视频平台接收到视频点播令牌的结果，将该视频点播令牌发送给该电视云。
另外，另一要解决的课题在于，不用对电视接收机进行遥控器操作，就能够进行VOD内容的收看等的合同所涉及的ID、密码的输入。
电视网关被配置于视频平台与电视接收机之间，进行用于将来自所述视频平台的动态图像内容提供给所述电视接收机的连接，从用户的移动终端，接收对作为所述电视接收机相对于所述电视网关的认证的中介的电视云、所述电视接收机、所述移动终端进行确定的信息，从所述视频平台，接收对基于经由所述移动终端的输入而认证的用户的所述移动终端与所述视频平台同时进行识别的MA-ID，从所述电视云接收对所述电视接收机以及所述电视云同时进行识别的HA-ID，将与相同的用户相关的所述MA-ID与所述HA-ID建立关联作为ID结合信息而存储于规定的存储部。
另一要解决的课题在于，提供一种能够避免向服务器的访问集中的电视接收机及电视系统。
电视接收机是接收经由服务器而发布的内容信息的电视接收机，其具备负荷平均化部，该负荷平均化部基于该电视接收机所具有的固有信息来实现上述服务器中的负荷的平均化。
通过本申请的结构，视频网关能够进行与AVOD、SVOD、TVOD对应的混合服务，而且，不用向电视接收机进行遥控器操作，就能够进行VOD内容的收看等的合同所涉及的ID、密码的输入。

具体实施方式
本申请利用电视网关，将多个视频平台与多个电视接收机连接，从而使得动态图像内容的选择容易，能够进行良好的动态图像内容的分发。通过本系统，不仅简单的动态图像收看，还能够实施从动态图像内容向EC(电子商务交易)网站引导并购入商品、根据因特网上的Web信息(例如新闻、票务信息等)通过动态图像来确认详细等所谓的将动态图像与Web信息连结的交互式的服务。
除了这种高度的服务的实现以外，近年来，还进行以各种方式的动态图像内容的提供。例如，任何时候都能够收看想要的动态图像内容的动态图像分发服务被称为VOD(Video On Demand)，当前存在各种VOD方式。
若大体进行分类，存在被称为AVOD(Advertising Video On Demand)的广告动态图像分发服务、被称为SVOD(Subscription Video on Demand)的定额动态图像分发服务、以及被称为TVOD(Transaction Video On Demand)的租赁型的动态图像分发服务。
在AVOD中，能够免费进行动态图像收看，但登载广告。因此，收益不仅可从收看动态图像的收看者得到，还可从播出广告的企业得到。另一方面，SVOD是若支付月度费用，则能够收看任何数量的所准备的动态图像内容。进一步地，在TVOD中，例如能够赋予一周等的限制来观看单个动态图像内容。因此，SVOD、TVOD从收看动态图像的收看者得到收益。
如以上那样，存在多种多样的动态图像分发服务，在基于电视接收机的收看中，希望能够灵活对应这些方式、并且收看者能够不混乱地简单地欣赏的动态图像分发系统。因此，作为上述的电视网关的功能，需要针对这种方式的对应。
本申请提供一种向使用网络而实施的、能够通过性能、功能不同的电视接收机来接收从多个动态图像分发平台送出的动态图像内容的电视网关追加与AVOD、SVOD、TVOD等的各种VOD方式对应的功能、并且能够更加简单地进行动态图像内容的选择的新的动态图像分发系统。此外，在AVOD时，提供广告动态图像的更加有效的提示方法。
电视网关通过能够将多个视频平台与多个电视接收机连接，来实现更加高度的交互式的服务。特别地，通过对不同功能、性能的电视接收机提供标准的动态图像内容的选择方式，容易在不损害用户方便性的情况下进行针对更多动态图像内容的选择。
但是，在基于电视网关的动态图像内容的选择中，虽然存在广播形式下的线性频道、换句话说、使用了网络的动态图像分发，但如广播那样，以基于对应于时刻信息来单方地持续分发的方式的分发方式为主要着眼点，能够一部分地进行推荐节目的提示，但难以对应于各种VOD方式。这样，基于线性频道的动态图像内容的提供由通常免费的动态图像内容和广告构成，是AVOD的一种。然而，不仅AVOD，SVOD、TVOD这种不同的动态图像分发服务也正在普及，因此针对这些VOD方式的对应也很重要。
在AVOD中，通过登载广告，虽然能够收看免费的动态图像内容，另一方面，SVOD通过月度费用能够自由地收看动态图像内容，关于TVOD，购入单个动态图像内容，从而 在有限的期限内能够收看动作内容。为了对应于这些，需要确认收看者的合同状况，在现有的电视网关系统中难以对应。
此外，在AVOD中，通过广告而从企业得到收入，因此广告的有效的提示方法是必须的。相关技术的电视网关中存在广告的插入功能，存在对各个电视接收机实施瞄准广告的功能，但未提供更加有效的提示的方法的具体方法。此外，近年来，从AVOD向SVOD的服务引导，或者将通过TVOD而提供的收费内容的销售等组合的混合服务被提供。为了通过相关技术的电视网关来实施这种混合服务，需要收看者的合同条件的确认、广告与VOD的联动功能，因此需要合理地装备这些功能。
图1中表示影像分发系统的结构图。
在图1中，CSP(内容服务提供商)1301～1308提供动态图像内容。动态图像内容分别被输入到视频平台1311～1313。视频平台1311～1313将动态图像内容输入到电视网关1321，经由电视云1331～1334而向电视接收机1341～1350送出。
各个视频平台在分发方式上存在不同，因此各个动态图像内容仅被有限的电视接收机接收。虽然存在电视网关转换动态图像内容的格式的方式、在视频平台内置转换器的方式，但图1中的视频平台1311～1313中，是内置转换器的方式。此外，电视云分别对应于性能、功能不同的电视接收机。处于各电视云的管理下的电视接收机几乎被连接为相同性能、功能，性能、功能不同的电视接收机与各个电视云连接。通过电视云对不同的电视接收机进行转换，即使功能、性能不同也能够进行良好的动态图像内容的选择以及接收。通过以上，在具有电视网关的动态图像分发系统中，能够将格式不同的多个视频平台的动态图像内容分发给性能、功能不同的电视接收机。
动态图像内容暂时经由电视网关1321而被输入到电视，若连接建立，则视频流本身能够从视频平台1311～1313直接输入到电视1341～1350。另外，电视1341～1350与移动终端1301～1310连接，进行TV-ID(分别赋予给电视1341～1350的ID)与SP-ID(分别赋予给收看者的移动终端1301～1310的ID)的结合。这些被结合的信息被保管于TV-ID和SP-ID的结合信息保存部1352。此外，从电视接收机1341～1350输出的收看数据被补充到收看数据保存部1351。通过保管于收看数据保存部1351的收看数据和TV-ID与SP-ID结合信息保存部1352的输出，通过内容推荐信息保存部1353来进行内容的推荐。从广告服务器1355输出的广告内容通过内容推荐信息保存部1353的输出，利用推荐广告选择插入部1354，选择适当的广告，利用视频平台1311～1313，插入广告。此外，在接收侧广告插入部1356中，通过电视接收机的功能来进行广告的插入。
图2是显示于电视的节目表的说明图。由视频平台提供的动态图像内容如广播那样，通过在规定的时间持续流动的线性分发而被提供给电视，因此通过表示与广播同样的频道和时刻的节目表来选择动态图像内容。
进一步地，在网关中，通过将收看者具有的SP-ID1421与识别电视的TV-ID1422连结，能够将节目表定制化。根据本电视接收机的收看者的收看倾向，推荐内容1401～1403被覆盖显示在节目表上。在本例中，属于视频平台1411的移动的ID(SP-ID)1421与本电视接收机的ID(TV-ID)1422连结，因此特别推荐从视频平台1411提供的动态图像内容。
该节目表由从电视网关供给的共用EPG数据1404构成。EPG共用数据1404中，至少包含表示时刻信息的时间表、具有节目的说明等信息的节目原始数据、进行频道的显示 等的标题数据。
通过以上的结构，各个视频平台能够在不在意具有不同性能、功能的电视接收机的功能(面板的大小、像素数、分辨率等)的情况下，输入到电视网关，从而向更多的电视接收机提示内容。进一步地，通过使以电视接收机和智能手机为代表的移动终端协作，能够取代操作性不同的单功能的遥控器，实现使用移动终端的针对高度服务的操作性提高，进一步地能够进行相关技术中的遥控器中不能进行的高度的智能手机与电视的协作动作。
在使用了电视网关的动态图像的分发系统中，针对不同功能、能力的电视能够提示节目表，能够在不将从各种视频平台分发的动态图像内容混乱的情况下，收看者进行选择。这样，对于线性频道分发方式的动态图像内容，是极其有效的系统，但对于其它的动态图像内容的分发方式，功能不足，难以对应。
在视频网关中，需要提供与AVOD、SVOD、TVOD所对应的混合服务有关的功能。
本申请对形成节目表的数据新追加多个VOD分发方式所对应的数据，实现容易地选择通过AVOD、SVOD、TVOD而分发的动态图像内容的功能，此外，通过改善节目表的构造，提供更加舒适地选择基于线性频道分发的动态图像内容的功能。另一方面，上述通过将形成追加的节目表的数据应用于广告显示，对收看者实现更加有效的广告提示。
如上述那样，以下，将构成基于本申请的节目表的数据称为“节目表构成信息”来进行说明。通过节目表构成信息，构成AVOD、SVOD、TVOD的混合动态图像选择系统，并且能够进行线性频道的摘要收看、预告动态图像内容收看。此外，能够进行基于覆盖方式的广告提示、将动态图像广告内容与VOD组合的可点播VOD。
以下，基于附图来对节目表构成信息的结构以及分配方式的说明、能够容易选择未来节目、当前节目、过去节目的新的节目表的结构方法、也对应于AVOD、TVOD、SVOD的任意分发方式的节目表的结构以及提示方式、将VOD与广告组合的更加有效的广告提示的方法、未来节目的预告动态图像内容、过去节目的摘要收看、以及紧急变更节目表构成信息的紧急消息进行说明。
第1实施方式
图3中表示与本申请有关的第1实施例。
CSP(内容服务提供商)101～108提供动态图像内容。动态图像内容分别被输入到视频平台111～113。视频平台111～113将动态图像内容输入到电视网关121，经由电视云131～134来向电视接收机141～150送出。
如以上那样，将动态图像内容分发到电视接收机的功能与图1相同。与图1的使用了电视网关的影像分发系统较大不同的方面在于，视频平台111～113与订阅者数据库191～193连接。订阅者数据库191～193蓄积、保存对从视频平台111～113分发的动态图像内容进行收看的收看者的合同条件。因此，视频平台111～113通过在任意时候向订阅者数据库191～193进行询问，能够确认收看者的合同条件。
另一方面，图1所示的动态图像分发系统的TV-ID与SP-ID的结合信息保存部1352在基于本申请的动态图像分发系统中，为MA-ID与HA-ID的结合信息保存部152。这里，HA-ID以及MA-ID分别是Home Agent ID与Mobile Agent ID的简称，HA-ID是对电视云与电视接收机进行识别的ID，MA-ID是对视频平台与移动终端的用户进行识别的ID，为复合的标识符。订阅者数据库111～113能够通过MA-ID来确定用户，确认其收看条件。
另外，电视141～150与移动终端171～180连接，进行HA-ID与MA-ID的结合。这些被结合的信息被保管于MA-ID与HA-ID的结合信息保存部152。在基于本申请的影像分发系统中，通过使MA-ID与HA-ID的结合信息保存部152和订阅者数据库191～193联动，来对应于各种VOD分发方式。
此外，关于收看数据保存部151、内容推荐信息保存部153、广告服务器155、接收侧广告插入部156，进行与图1所示的动态图像分发系统同样的动作。
图4中表示与本申请有关的第1实施例的动作。从图3所示的动态图像分发系统整体，提取视频平台111、电视网关121、电视云131、电视141和移动终端101来进行说明。其他视频平台以及电视云、电视接收机、移动终端也进行同样的动作。
在SVOD中，是被收取月费用的收看者能够随意观看动态图像内容的服务，在TVOD中，是收看者在有限的期间内购入单个动态图像内容从而能够收看收费的动态图像内容的服务。另一方面，在基于线性频道分发的AVOD中，能够自由进行动态图像收看，但进行广告的收看。如以上那样，通过VOD方式，收看者的收看条件不同，因此在确认了这些条件的基础上，动态图像分发系统需要对收看者提示动态图像内容。
在图4中，将识别视频平台111的ID设为PF-ID，将识别电视网关121的ID设为TG-ID，将识别电视云的ID设为TC-ID，将同时识别电视以及TC云的ID设为HA-ID，将同时识别移动终端101的用户和视频平台111的ID设为MA-ID。此外，将识别作为收看对象的动态图像内容的ID设为CT-ID。以下，关于进行VOD收看时的动态图像进行说明。
在电视接收机141中，请求VOD收看。电视接收机141通过信号151(1)将VOD令牌请求和通过CT-ID而识别的VOD内容、对提供动态图像内容的视频平台111进行识别的PF-ID、表示电视接收机自身的HA-ID同时发送给电视云131。所谓VOD令牌请求，是指发送用于确认具有观看VOD的权利的命令。电视云131通过得到的信号151，将信号152发送给电视网关121。信号152(2)包含VOD令牌请求、PF-ID、CT-ID、HA-ID。电视网关121通过自身具有的MA-ID和HA-ID的结合信息数据库，获取与HA-ID结合的MA-ID，确定请求收看的收看者。电视网关121将信号153发送给视频平台111。信号153(3)包含VOD令牌请求CT-ID、MA-ID。
接下来，视频平台111通过信号153(3)接收VOD令牌请求，通过信号154，(4)将MA-ID和CT-ID对订阅者数据库191进行询问，确认具有MA-ID的收看者的登记条件，通过信号155，(5)将结果向视频平台111回答。在具有可收看VOD的条件的情况下，视频平台111通过信号156(6)发布VOD令牌，将VOD令牌以及CT-ID和MA-ID发送给电视网关121。电视网关121获取信号156。电视网关121将信号157发送给电视云131。信号157(7)至少包含VOD令牌。电视云131将从电视网关121接收的VOD令牌，通过信号158，(8)发送给电视接收机141。
电视接收机141将信号159发送给视频平台。信号159包含通过信号159而得到的VOD令牌、识别动态图像内容的CT-ID。视频平台111根据得到的CT-ID来确定表示动态图像的场所的URL，确认VOD令牌的正当性。在确认VOD令牌有效后，通过信号160，(10)从视频平台111向电视接收机141进行动态图像流的分发。
通过以上的动态图像，控制可否进行符合VOD收看条件的VOD内容的收看。
进行与本申请有关的构成节目表的“节目表构成信息”的说明。在本申请中，节目表构 成信息301被从视频平台111发送，经由电视网关121以及电视云131，发送给电视接收机141。
这里，节目表构成信息301包含通过PF-ID而识别的运营商信息302、通过Service_id而识别的频道信息303、通过Event_id而识别的节目信息304、通过CM_id而识别的CM信息305、通过Vod_id而识别的VOD信息306。此外，包含表示节目的时间轴上的位置的时间表311以及表示广告的显示位置的布局信息321。图5中表示各个信息的结构内容。
运营商信息302包含运营商ID(PF-ID)、运营商名、运营商缩略图像、标识。

图6中表示使用节目表构成信息而构成的节目表的例子。
视频平台111将信息提供给电视网关121。电视网关121将从视频平台111获取的节目表构成信息分发给电视云131。
基于电视云131的节目表构成信息存在已经从电视网关121分发的过去的节目表构成信息和从现在开始分发的预定的节目表构成信息，通过能够之后收看错过的节目，提高收看者的节目选择的便利性。电视云131向电视141发送该过去的节目表和未来的节目表。
电视141中构成过去的节目表时，根据节目表构成信息的运营商信息402，识别在哪个的视频平台构成的频道。例如，根据频道信息403来进行节目表的频道显示，根据节目信息404至406，构成各节目的排列以及说明。根据时间表信息407，提示节目表的时间线。这些是过去已经分发的节目，能够自由地选择。
进一步地，本节目表中提示VOD内容的一览。这选择提示节目表构成信息中包含的VOD信息。各个VOD信息中具有表示内容的CT-ID，暂时保存VOD信息数据库432之后，通过推荐选择部431，进行VOD内容的选择，在节目表上进行提示。与过去广播的节目同样地，能够自由选择VOD内容，因此能够对收看者提供舒适的节目选择功能。换句话说，过去节目表对于收看者来讲，不是最新内容，没有时间的制约，赋予能够自由选择的便利性。在本实施中，将VOD内容显示仅配置于过去节目表，但对当前、未来的节目表能够使用同样的数据和动作来进行配置。
在图6的过去、当前、未来的节目表将视频平台提供的节目作为频道而显示。在本图中，频道A1、频道A2是视频平台A提供的频道，频道B1是视频平台B提供的频道。各节目表中进行显示的VOD内容1～4能够选择对收看者通过遥控器等而聚焦的节目内容进行分发的视频平台所提供的VOD信息并进行显示。即，在收看者通过遥控器而聚焦了内容A11的情况下，将视频平台提供的VOD显示在节目表画面上。
另一方面，在电视141中当前节目表构成信息中，基于当前分发中的节目，构成节目 表411。此外，在未来节目表中，根据未来节目表构成信息中包含的运营商信息422、频道信息423、节目信息425～426、时间表427，提示分发预定的节目。
图7中表示电视141中的节目表的步骤。若按下遥控器的节目表按钮，则首先显示当前节目表511。通过从当前节目表511选择节目来播放动态图像内容512。这些通过输入遥控器的上下键、频道编号，能切换节目，此外，也能够直接选择其他节目513。此外，通过在收看中途按下节目表按钮，也能够返回到原始的当前节目表514。
另一方面，在当前节目表511中，通过按下向下滚动按钮，来提示未来节目表521。若从未来节目表521选择节目，则由于还未分发，因此提示节目的说明画面522。这里，在能够播放预告动态图像的情况下，提示预告按钮，通过按下，播放预告动态图像523。若预告动态图像结束则返回到未来节目表524。
通过从当前节目表511向上滚动，提示过去节目表501。过去节目表501中提示过去分发的节目和VOD内容。在选择了VOD内容的情况下，移至VOD选择步骤505。关于VOD选择步骤，通过图8来进行说明。在从过去节目表501选择了节目的情况下，暂时提示节目说明画面502。这里，在能够收看过去节目的摘要的情况下，提示摘要按钮，若收看则播放摘要506。若从说明画面502按下收看按钮，则播放过去节目的动态图像内容，若结束则返回到过去节目表504。通过播放摘要动态图像能够使内容选择更加方便。
如以上那样，在未来节目表中，收看预定分发的预告动态图像，在过去节目表中，收看摘要，从而能够提高节目收看的方便性。此外，由于在过去节目表进行能够VOD选择的显示，因此能够进行期望的VOD内容的收看。
图8中表示电视141中的根据节目表的VOD收看步骤。若按下节目表按钮，则提示当前节目表611。若从当前节目表611选择节目，则播放节目612。在节目612的主剧情动态图像的中途或者结束插入广告动态图像613，与广告动态图像613一起提示VOD按钮。若按下VOD按钮，则提示VOD的说明画面614。此时，在VOD是基于SVOD的服务的情况下，提示说明画面614，在基于TVOD的服务的情况下提示说明画面621。在说明画面614提示收看按钮，在说明画面621提示购入按钮和金额。
这里，若按下VOD收看按钮，则成为3个分支。第1分支为在收看者未进行月费用会员登记的情况下，进入会员登记画面615，在智能手机上，会员登记应用625进行动作，实施会员登记。进一步地，进入ID绑定画面616，在电视画面上提示QR代码(注册商标)，通过在智能手机上进行动作的ID绑定应用626，电视接收机的HA-ID与会员ID即MA-ID结合。
第2分支在说明画面614上已经会员登记结束的情况下，进入ID绑定画面616。若ID绑定结束则再次进入SVOD说明画面617，通过按下收看按钮，VOD动态图像618被播放。TVOD的情况下，提示TVOD说明画面627，支付规定的购入金额，进入动态图像收看618。若VOD的动态图像播放结束，则返回到主剧情动态图像619。
第3分支在ID绑定已经结束的情况下，通过从SVOD说明画面614按下收看按钮，直接进入到VOD动态图像播放618。
另一方面，在选择了过去节目表601的VOD内容的情况下，进入SVOD说明画面614或者TVOD说明画面621。以下，以同样的步骤播放动态图像618，结束时，返回到过去节目表629。
通过以上的步骤，能够容易收看VOD。另外，为了实现该收看步骤而进行图4中说 明的获取VOD令牌的动态图像。根据说明画面614，在选择收看时，获取VOD令牌的步骤进行动作，若VOD令牌获取失败，则进入会员登记画面615或者ID绑定画面616，在ID绑定结束后，通过从SVOD说明画面617再次按下收看按钮，进入再次获取VOD令牌的动作，在VOD令牌获取后，播放主剧情动态图像619。
图9中表示与本申请有关的广告的提示例。提示模式存在3种，表示插播插入提示701、覆盖显示711、可点播VOD721。
作为第1模式的插播插入在主剧情前702播放后，提示广告703，提示主剧情后704。在画面上，在提示主剧情动态画面705、广告动态画面706的提示后，播放主剧情动态画面707。本模式是对所谓的动态图像内容插入广告动态图像内容的例子。
作为第2模式的覆盖显示将广告在主剧情动态图像上重叠提示。插播插入在时间上被广告插入，因此时间延伸，与此相对地，在覆盖显示中，具有在主剧情动态图像上直接重叠显示广告因此不影响动态图像内容的尺寸的长度的特征。在播放主剧情动态图像712时，从动态图像画面715，重叠广告，成为动态图像画面716，进一步成为动态图像画面717。在此，通过处于广告信息的自动提示节目的信息，自动消除重叠的广告，移至动态图像画面717。在本提示方法中，如上述那样未发生时间上是插入，但画面被局部隐藏。
第3模式是可点播VOD721，是插播插入701与覆盖表711的组合。与插播同样地，从主剧情动态图像722播放广告723，播放主剧情动态图像724。此时，从动态图像画面725的状态移至广告动态图像画面723、动态图像画面726。这里，若在广告动态图像内容提示按钮并按下，则显示说明画面728，进一步若按下收看按钮则播放VOD内容729。若在广告画面726未按下按钮，则主剧情动态图像724在广告723结束后播放。若VOD内容729结束，则播放相同频道的动态图像内容730。
在各个情况下，将节目表构成信息的状态表示为741、742、743。
在实施插播插入的情况下，节目表构成信息741包含运营商信息、频道信息、节目信息、广告信息。覆盖显示的情况也同样。可点播VOD的情况下，广告信息中进一步包含VOD信息。在覆盖显示以及可点播VOD的情况下，通过图10所示的布局信息，构成画面。
图10中表示与本广告的提示有关的布局。
根据主剧情动态图像801，在提示覆盖显示画面802时，通过处于节目表构成信息的布局信息805来构成画面。布局信息805中包含影像的坐标、影像的尺寸以及静止图像坐标、尺寸的信息，能够构成L字型显示802或者重叠矩形区域的显示803。另外，在自动地进行覆盖显示时，通过处于节目表构成信息的CM信息中的自动开始标志和开始时间来自动地实施覆盖显示。
在本例中，作为可点播提示，示例2个模式。第1模式是可点播广告，在按下按钮后，能够进行其他EC网站、信息提示。第2模式是可点播VOD，通过图9所示的步骤能够进行提示。
在可点播VOD的情况下，从主剧情的动态图像画面801，播放广告动态图像842，通过按下在广告动态图像842提示的按钮842，移至VOD说明画面823。这里，通过按下收看按钮，播放VOD的动态图像824。在广告动态图像822，按钮842根据布局信息825而被确定提示位置。VOD说明画面823的收看按钮也同样地根据布局信息进行配置。
可点播广告的情况下，在广告动态图像812基于布局信息815，提示按钮841。在按 下按钮841时，提示EC网站的商品画面813。在此，例如也能够进行详细的信息画面等的提示。
如以上那样，根据节目表构成信息所具有的布局信息，能够进行灵活的画面构成。
图11中通过节目表构成信息，表示使用了当前节目的运用例。
当前节目表911显示当前被分发的内容。节目表构成信息900中，加入运营商信息902、频道信息903。频道信息903中，存在节目信息904、906、908，分别在节目信息904中存在广告信息905，在节目信息906中存在广告信息907，在节目信息908中存在广告信息909，进一步地，在广告信息909中包含VOD信息910。
在各个节目信息中，记载了节目开始时间、节目结束，此外，在广告信息中也记载了广告开始时间和结束时间。
通过节目表构成信息中包含的以上的信息，构成节目表，此外，播放主剧情动态图像和广告921～927。另外，将同时提示的画面表示为931～937。
在节目信息904中记载了节目开始时刻8：00和结束时刻9：00。进一步地，在广告信息中记载了开始时刻8：30、结束时刻8：35。从时刻8：00开始主剧情动态图像，从8：30开始播放广告。进一步地，从8：35返回到主剧情动态图像并继续播放。
下个节目924从9：00开始。表示下个节目。在节目信息906中记载开始时刻9：00、结束时刻11：00。在广告信息907中记载开始时刻10：00、结束时刻10：05，表示通过覆盖进行显示。根据这些信息，从时刻9：00开始主剧情动态图像924播放。主剧情动态图像播放的中途从10：00自动地显示静止图像的广告。将被提示的画面表示为934。广告作为静止图像而被重叠显示于主剧情动态图像上。重叠的广告即静止图像在10：05消失。
接下来，在下个节目信息中，记载了开始时刻11：00、结束时刻12：00，广告信息记载了开始11：30、结束时刻11：40。本广告记载了指示以使得通过按钮显示而跳到另外画面。根据本信息，下个节目925在11：00开始。广告926在11：30开始，如广告画面936所示，在本广告提示按钮。通过收看者按下按钮，进入VOD步骤，提示VOD的选择画面938。以下，根据图8所示的VOD步骤而进行动作。在未按下按钮的情况下，主剧情动态图像927的播放继续，如动态图像画面937所示，广告消失。
这样，通过节目表构成信息，构成节目，但另外地，动作流的播放可根据动态图像流中包含的原始数据(清单文件)来进行播放。作为例子，图11中表示通过作为国际标准的MPEG DASH而播放动态图像流的情况。在MPEG DASH中，在动态图像流的播放中使用MPD(Media Presentation Description)。在MPD中，通过Period来规定动态图像流。例如，基于本实施例的节目921由MPD#1：951构成，动态图像921被播放。广告922通过Period#2：942来播放，动态图像923通过Period#3：943来播放。同样地，下个节目的动态图像924通过MPD#2：952的Period#1：944来播放。进一步地，下个节目通过MPD#3：953的Period#1：945来播放动态图像925。广告926通过Period#2：946来播放，动态图像927通过Period#3：947来播放。在本例中，使一个MPD对应一个节目，但根据运用，也能够进行不同的对应。例如，也能够使一个MPD对应2个以上的节目，通过多个Period来进行规定。
图12中表示与本申请有关的过去节目表下的运用例。节目表构成信息包含运营商信息1002、频道信息1003、节目信息1004、广告信息1005、VOD信息1006。通过这些信息，显示过去节目表1001。根据频道信息1003中包含的节目信息1004，播放动态图像1021、 广告1022、动态图像1023。这里，存在节目开始时刻8：00、结束时刻9：00的记述，但表示过去被分发的时刻，因此能够自由进行节目的选择。
若选择动态图像1021，则暂时提示说明画面1041，若按下收看按钮，则1个主剧情动态图像1021被播放。进一步地，广告动态图像1024被播放，然后，成为主剧情动态图像10，若广告动态图像结束则成为主剧情动态图像画面1033。
图12的过去节目表中将视频平台提供的节目显示为频道。在本图中，频道A1、频道A2是视频平台A提供的频道，频道B1是视频平台B提供的频道。各节目表中进行显示的VOD内容1～4能够选择对收看者通过遥控器等而聚焦的节目内容进行分发的视频平台所提供的VOD信息并进行显示。即，在收看者通过遥控器等而聚焦内容A11的情况下，将视频平台提供的VOD显示在节目表画面上。在本实施例中，将VOD内容显示仅配置于过去节目表，但也能够在当前、未来的节目表使用同样的数据和动作来进行配置。
另一方面，若选择VOD则播放VOD动态图像1024。这里，在播放前，提示VOD的说明画面1042，若按下收看按钮，则播放VOD动态图像1024。此时，动态图像画面成为VOD动态图像画面1033。若VOD动态图像结束则返回到过去节目表画面1035。
与当前节目表同样地，关于过去节目表也对与基于MPEG DASH的动作流的播放的关系进行说明。根据MPD#1：1050的Period#1：1051，播放本件动态图像1021。根据Period#2：1052，播放广告1022、根据Period#3：1053，播放主剧情动态图像1023。关于VOD，根据MPD#2：1052的Period#1：1054，播放VOD动态图像1024。与当前节目表的运用同样地，也能够进行基于一个MPD和多个节目的关系的运用。
图13中表示节目表构成信息的更新。
节目表构成信息1111例如以一天为单位定期进行更新。节目表构成信息中，包含运营商信息、频道信息、节目信息、广告信息、VOD信息。
定期地，电视网关121通过信号1101来向视频平台111请求节目表构成信息。视频平台111通过信号1102来向电视网关121发送节目表构成信息。电视网关121在获取更新节目表构成信息之后，将通常为OFF的更新标志1121设为ON。电视云131定期地确认电视网关121的更新标志1121。若更新标志1121为ON，则通过信号1104来获取节目表构成信息，通过信号1105，向电视接收机141分配的电视云131获取节目表构成信息之后，更新标志1121立即成为OFF。但是，在存在多个电视云的情况下，在确认全部电视云获取到节目表构成信息之后，设为OFF。此外，在从电视网关121获取节目表构成信息时，为了更加确保安全性，通过预先对电视云131分配的密钥，进行加密从而能够保证安全。
图14中表示紧急消息的更新。
如图13所示，节目表构成信息的信息量较多，内部包含缩略图像等，因此例如以一天单位那样较长的周期进行更新。因此，例如，难以进行现场直播的节目延长、必须变更节目表的情况等向紧急事态的对应，因此需要另外必要最低限的尺寸且用于进行变更处理的紧急消息功能。将紧急消息的格式表示为1210。
<紧急消息ID><频道ID><作为对象的节目ID><对象项目><处理><处理内容>这里，<紧急消息ID>在运营商内唯一地发布，因此包含<运营商ID+唯一ID>，通过Emsg_id来表示。
<频道ID>是确定各频道的Service_id，<作为对象的节目ID>是确定节目的Event_id。 <对象项目>是处于节目信息内的各项目。
<处理>存在删除、改写(变更)、追加，将其具体内容规定为<处理内容>。
例如，在将8：00开始、9：00结束的节目的结束时间变更为9：30时，将<处理>变更、<处理内容>9：30发送给目标节目。
视频平台111通过信号1201，将紧急消息发送给电视网关121。电视网关121将通常为OFF的紧急标志1221设为ON。电视云131通过信号1202，确认紧急标志1221。此时，电视云131以比所述更新标志1121的确认更短的期间进行确认。例如，以10分钟～30分钟等的期间进行确认。获取到紧急消息的电视云131向电视接收机141发送紧急消息。电视云131通过信号1203，获取紧急消息。电视云131将获取的紧急消息通过信号1204来分配给电视接收机141。这里，紧急消息的分配可以比节目表构成信息的分配短的时间进行分配，通过被预先设定为发送不集中的偏离时间，各电视接收机控制接收定时，使访问分散。
第15图中表示与本申请有关的电视接收机1101(与141相同)的结构图。
通过天线1101，接收广播，通过调谐器1102，转换为数字流的广播内容通过信号处理部1103而被转换为声音信号、影像信号。声音信号被声音处理部1104处理，通过扬声器1106来播放声音。此外，影像信号被影像处理部1105处理，通过影像显示部1107来播放影像。CPU1109与存储器1108、非易失性存储器1110连接，执行控制程序，进行调谐器1102的控制、信号处理部1103的控制。另外，用户的操作被从遥控器1113输入到接收部1112，输入到控制程序。通信接口1111接收从网络分发的动态图像内容、内容选择画面，通过CPU1109的控制程序来进行处理。
图6的结构以及图7的播放步骤将经由通信接口1111而得到的图5的节目构成信息蓄积于存储器1108。CPU1109使用在内部执行的软件，基于当前时间来切分节目信息，生成当前节目表、过去节目表、未来节目表。

ID结合信息DB120被存储于例如电视网关121所具备的(或者，电视网关121的CPU1702可参照的)HDD(Hard Disk Drive)等的存储装置。ID结合信息DB120存储图24、图23中以表格的形式示例的信息。
图24是表示用于对ID结合信息DB120存储的会员以及其权利状况进行识别的信息的一例的图。更加详细地，图24所示的表格针对MA-ID，将HA-ID、访问令牌、刷新令牌、有效期限、用户概况等建立关联并进行存储。访问令牌是表示许可向电视云131的访问的令牌。有效期限是访问令牌的有效期限，若超过该有效期限，则访问令牌失效。刷新令牌是在获取新的访问令牌以及有效期限时使用的令牌。
这里，MA-ID是同时识别移动终端109的用户和视频平台111的ID。这里，移动终端109例如是用户所具有的智能手机等的便携终端设备。HA-ID是同时识别电视接收机141以及电视云131的ID。因此，在用户持有多个播放设备(例如电视接收机141)的情况下，可能对一个MA-ID将多个HA-ID建立关联。此外，按照每个与MA-ID建立关联的HA-ID，存储访问令牌、刷新令牌、有效期限等。
图23是表示ID结合信息DB120存储的用于对播放设备(例如电视接收机141)进行识别的信息的一例的图。更加详细地，图23所示的表格针对HA-ID，将MA-ID、访问令牌、刷新令牌、有效期限等建立关联并存储。访问令牌是表示许可向视频平台111的访问的令牌。有效期限是访问令牌的有效期限，若超过该有效期限，则访问令牌失效。刷新令牌是在获取新的访问令牌以及有效期限时使用的令牌。
这里，可能用户通过一个播放设备(例如电视接收机141)来利用多个视频平台111提供的VOD服务。该情况下，可能将多个MA-ID针对一个HA-ID建立关联。此外，按照每个与HA-ID建立关联的MA-ID，存储访问令牌、刷新令牌、有效期限等。
返回到图23，按照步骤来说明到ID绑定为止的信号的收发。首先，若电视接收机141通过遥控器操作等，接收请求VOD收看的操作，则通过信号1901，对电视云131，(1)请求QR码(注册商标)。信号1901中至少包含HA-ID。
接收到(1)的QR码请求的电视云131通过信号1902，对电视接收机141，发送(2) 用于显示QR码的信息。这里，信号1902的QR码至少包含对提供VOD内容的视频平台111进行识别的PF-ID、能够确定表示电视接收机自身的HA-ID的信息。接收到信号1902的电视接收机141使画面显示QR码。
接下来，移动终端109对在电视接收机141的画面显示的QR码进行拍摄，基于通过解码而得到的信息，通过信号1903，(3)进行Web访问。此时的访问对象是电视网关121。接收到信号1903的电视网关212通过信号1904，对QR码中包含的PF-ID所示的视频平台111，(4)进行认证请求。
接收到信号1904的视频平台111通过信号1905～1906，(5)进行ID登记确认。在该ID登记确认中，视频平台111经由移动终端109，对用户求取登录操作。
这里，对移动终端109侧的显示状态以及操作接收进行补充。若用户对电视接收机141，通过遥控器来请求VOD收看，则在电视接收机141的画面显示QR码，因此通过移动终端109来对此进行拍摄，使移动终端109的画面显示QR码导出的Web页面。此时的Web页面例如是电视网关121提供的。此外，此时的Web页面例如包含用于确认是否许可在下个画面求取用户的登录操作的操作按钮。若用户操作该操作按钮，则在移动终端109显示用于用户输入VOD收看合同中指定的ID、密码的画面。用于输入此时的ID、密码的画面是视频平台111提供的。经由该画面，视频平台111接收用户的ID、密码的输入，使基于信号1905～1906的(5)ID登记确认结束。
返回到基于图23的说明。视频平台111通过信号1905，对订阅者数据库191发送用户的ID、密码。若用户的ID以及密码在VOD收看合同中有效，则订阅者数据库191对视频平台111，通过信号1906，发送MA-ID。
结束(5)的ID登记确认并得到MA-ID的视频平台111通过信号1907对电视网关121，(6)发送响应。到此为止，电视网关121识别用户对视频平台111进行VOD收看的合同签订。
接收到(6)的响应的电视网关121接下来通过信号1908对视频平台111，(7)发送令牌请求。接收到(7)的令牌请求的视频平台111通过信号1909对电视网关121，(8)发送VPF令牌响应。
接收到(8)的VPF令牌响应的电视网关121接下来通过信号1910对电视云131，(9)发送令牌请求。接收到(9)的令牌请求的电视云131通过信号1911对电视网关121，(10)发送TVC令牌响应。
接收到(10)的TVC令牌响应的电视网关121接下来通过信号1912对视频平台111，(11)发送概况请求(Profile request)。接收到其的视频平台111通过信号1913对电视网关121，(12)发送概况以及MA-ID。
接收到(12)的概况以及MA-ID的电视网关121接下来通过信号1914对电视云131，(13)发送概况请求。接收到此的电视云131通过信号1915，(14)发送概况以及HA-ID。
通过到此为止的流程，电视网关121得到与用户的概况建立关联的MA-ID和HA-ID。接下来，电视网关121(15)进行ID绑定，使ID结合信息DB120存储MA-ID与HA-ID的结合信息(例如图24以及图23中以表格形式示例的信息)。
这样，通过本实施方式，在某个播放设备(电视接收机141)中的初次的VOD收看时，能够进行通过移动终端109的输入操作。移动终端109例如是智能手机，是容易进行文字输入的终端。因此，根据本实施方式，能够通过移动终端109来进行若是以往则必须 使用遥控器的ID、密码的输入作业，因此能够大幅度减轻输入操作的繁琐度。
此外，根据本实施方式，通过电视接收机141、电视云131，能够在不管理能够进行针对视频平台111的用户的登录的ID、密码的情况下，只要令牌有效，则能够进行电视接收机141相对于视频平台111的连接。换句话说，应为秘密的信息即ID、密码仅被视频平台111管理，能够排除从其他装置(电视网关121、电视云131、电视接收机141)泄露的可能性。
图24是对电视网关121中的ID提供所涉及的信号的流动进行说明的图。该图中表示具有某个VOD收看合同的用户通过某个播放设备而进行的第二次以后的VOD收看时的信号的流动。
电视网关121具备CPU1702执行规定的程序从而实现的功能部即结合信息参照部1706。若通信I/F(Interface，接口)1704从视频平台111接收MA-ID，则结合信息参照部1706参照ID结合信息DB120，获取MA-ID所对应的HA-ID，将其发送给电视云131。此外，若通信I/F(Interface，接口)1704从电视云131接收HA-ID，则结合信息参照部1706参照ID结合信息DB120，获取HA-ID所对应的MA-ID，将其发送给视频平台111。
接下来，说明网络节目表数据的交接方法。
图25是示出网络节目表获取及显示的流程的序列图。如图25所示，视频平台111～113与电视接收机141～150之间的网络节目表数据的交换经由电视网关121来进行。
视频平台111～113将网络节目表数据上传到电视网关121的规定区域(EPG S3)(步骤S1)。电视网关121将被上传的网络节目表数据配置给网络节目表数据用的CDN(Contents Delivery Network：内容分发网络)。
电视接收机141～150对网络节目表数据用的CDN进行直接访问而获取网络节目表数据(步骤S2)。
此外，电视网关121对于各TV云131～134发行对它们分别进行识别的TC－ID，对于各视频平台111～113发行对它们分别进行识别的PF－ID，并发行频道编号。
在此，图26是示出视频平台111～113和TV云131～134的ID的预约例的图。如图26所示，对于与各TV云131～134对应的电视接收机的生产者，分别预约TC－ID。另外，如图26所示，对于各视频平台111～113的发布运营商，分别预约PF－ID。
另外，图27是示出其它ID的图。如图27所示，由拥有TC－ID的各电视接收机的生产者发行用于识别归属代理(Home agent)的HA－ID。由拥有PF－ID的各发布运营商发行用于识别移动代理(Mobile agent)的MA－ID。由发布运营商发行CS－ID，该CS－ID用于识别提供归属于运营商的视频的动态图像内容提供者即CSP。
电视网关121根据上述的PF－ID来制作运营商信息的清单(pfids.json)。视频平台111～113制作被分配的频道的频道信息的清单(channels.json)。这样，电视接收机141～150能够获取当前有效的频道的信息。
在此，图28是示出网络节目表数据的构成例的图，图29是示出网络节目表数据的构成信息例的图。
如图28所示，视频平台111～113供给提供服务的全部频道的过去1周内、当前、未来1周内的15天期间的节目信息(＜yyyymmdd＞.json)。而且，视频平台111～113制作在节目信息清单(＜yyyymmdd＞.json)中参照的视频信息(＜VOD－ID＞.json)、系列节目信息(＜series＿ID＞.json)、广告信息(＜AD－ID＞.json)。进一步，视频平台111～ 113制作想要向在过往节目表中显示的用户推荐的推荐节目信息即VOD清单(vodlist.json)。
如图29所示，网络节目表数据的构成信息除了包含上述的节目信息清单、视频信息、系列节目信息、广告信息、推荐节目信息之外，还包含作为设定信息的配置信息、日志服务器访问信息、运营商信息的清单、频道信息的清单、节目信息更新信息。
如图29所示，网络节目表数据的构成信息中的配置信息、日志服务器访问信息、运营商信息的清单、节目信息更新信息的制作者是电视网关121(在图29中记载为TGW)。另外，网络节目表数据的构成信息中的频道信息的清单、视频信息、系列节目信息、广告信息、节目信息清单、推荐节目信息的制作者是视频平台111～113(在图29中记载为VPF)。
在配置信息(Conf.json)中例如记载有服务器访问的峰移(peak＿sift)信息。配置信息的文件单位是整体地为一个。
在日志服务器访问信息(firehose＿params.json)中记载有用于向电视网关121的日志服务器(firehose stream)上传数据的访问秘钥信息。日志服务器访问信息的文件单位是整体地为一个。
在运营商信息的清单(pfids.json)中记载有发布节目的运营商的运营商信息、以及关于运营商正在进行服务的CS－ID的描述。运营商信息的清单的文件单位是整体地为一个。
在频道信息的清单(＜PF＿ID＞/channels.json)中记载有发布的节目的频道信息(service＿id)的信息。频道信息的清单的文件单位为每个视频平台111～113(在图29中记载为VPF)。
在视频信息(＜VOD－ID＞.json)中记载有在网络节目表数据中参照的、关于被发布的视频的信息。各节目信息以视频信息为基础而构成，播放的动态图像必定以视频信息为基础并根据视频类型来判断是否进行合同状况的确认，并用于播放。此外，对于有收看限制的信息，直到得到收看者的同意为止，不在画面上显示信息。视频信息的文件单位是每个视频平台111～113(在图29中记载为VPF)。
在系列节目信息(＜Service＿id＞.json)中，通过Service＿id(系列识别单位)来记述用于汇总连续剧、关联节目的清单，并按剧集编号顺序来排列VOD－ID。系列节目信息的文件单位是每个视频平台111～113(在图29中记载为VPF)。
在广告信息(＜AD－ID＞.json)中记载有在节目广播中在指定的时刻在画面上进行向推荐节目的引导的信息。此外，广告信息(＜AD－ID＞.json)不在网络节目表中显示。广告信息的文件单位是每个视频平台111～113(在图29中记载为VPF)。
在节目信息清单(＜yyyymmdd＞.json)中，按每个日期进行清单化而记载有网络节目表中显示的15天期间的范围内包含的节目信息。节目信息清单的文件单位是每个service＿id即1天单位。
此外，在上述的收看年龄限制设定为有效的情况下，参照的视频信息受限制的节目不直接显示于节目表，而是在用户的许诺后进行显示。
在推荐节目信息(vodlist.json)中，按照每个运营商记载有运营商推荐的VOD的VOD－ID清单。推荐节目信息的文件单位是每个视频平台111～113(在图29中记载为VPF)。
在节目信息更新信息(＜service＿id＞＿lastupdated.json)中，记载有作为更新了节目信息清单(＜yyyymmdd＞.json)的日期时间信息的节目信息更新信息。节目信息更新信息的文件单位是每个service＿id。
另外，电视网关121对于视频平台111～113，预先作为证书而配置client_ID(PF－ID)和client_secret。
视频平台111～113使用client_ID(PF－ID)和client_secret，将节目信息清单(＜yyyymmdd＞.json)上传到电视网关121的规定区域(EPG S3)(步骤S1)。
电视网关121若检测到视频平台111～113上传了网络节目表数据，则按照每个频道(service_ID)生成节目信息更新信息(＜service＿id＞＿lastupdated.json)，并与网络节目表数据一起配置于网络节目表数据用的CDN。
电视网关121按照每个频道(Service_id)生成节目信息更新信息(＜service＿id＞＿lastupdated.json)，并配置于网络节目表数据用的CDN。
节目信息更新信息被积蓄到视频平台111～113上传的规定区域和电视网关121配置的CDN。电视网关121能够清除每一天的节目信息更新信息的数据中的、8天以上过去的数据。
在视频平台111～113清除了规定区域上的数据的情况下，电视网关121能够对于广告信息(＜AD－ID＞.json)、视频信息(＜VOD－ID＞.json)、系列节目信息(＜Service＿id＞.json)清除CDN上的数据。
节目信息更新信息的内容如下。
Figure PCTCN2021119176-appb-000001
此外，在该节目信息更新信息不存在的情况下，最终更新日期时间的值设为0。
电视网关121生成用于获取节目信息更新信息的网络节目表数据获取用认证秘钥(API_key)。电视网关121预先制作具有访问网络节目表数据的权限的IAM用户，并每隔12小时地更新/获取网络节目表数据获取用认证秘钥(API_key)。此外，网络节目表数据获取用认证秘钥(API_key)设为24小时有效。网络节目表数据获取用认证秘钥(API_key)从制作起在24小时后被废弃。网络节目表数据获取用认证秘钥(API_key)不依赖于视频平台111～113、频道，而是共通地定期地更新。
TV云131～134每隔12小时从电视网关121获取网络节目表数据获取用认证秘钥(API_key)，并使得所属的电视接收机141～150能够获取。
电视接收机141～150在https中在x-api-key标头上附加网络节目表数据获取用认证秘钥(API_key)，从而获取节目信息更新信息。
视频平台111～113通常以1天1次的程度对节目信息更新信息进行更新。此外，视频平台111～113也能够在任意的时间对节目信息更新信息进行更新。
电视接收机141～150通过定期地核对电视网关121的网络节目表数据用的CDN中存在的<service＿id>＿lastupdated.json，从而能够检测节目信息更新信息已被更新了的情况。
电视接收机141～150的负荷平均化部1109a为了避免从电视接收机141～150向电视 网关121的访问集中，求出设备固有的access_shift_time(步骤S3)，关于详细内容在后叙述。然后，电视接收机141～150的负荷平均化部1109a在此后的网络节目表数据的获取、mpd的获取、上传日志时，反映access_shift_time，关于详细内容在后叙述。
另外，电视接收机141～150的负荷平均化部1109a同样地为了避免向电视网关121的访问集中，求出网络节目表的更新时刻的核对时间(epg_update_check_time)，关于详细内容在后叙述(步骤S3)。
电视接收机141～150通过与视频平台111～113的应用程序进行协作操作，从而在电视网关121上将PF－ID与MA－ID关联。
TV云131～134按照每个电视接收机141～150保持正在协作的状况，使得电视接收机141～150能够获取信息。
电视接收机141～150能够根据与视频平台111～113的协作状况来改变网络节目表的显示方式。
此外，在节目信息、视频信息中也可以包含“收看年龄限制设定”的信息。另外，在用户能够在电视接收机141～150上进行收看年龄限制的设定的情况下，电视接收机141～150按照收看年龄限制的设定而在网络节目表的显示、节目播放时施加收看年龄限制。优选这样的收看年龄限制能够通过PIN码输入等用户操作来解除。
接下来，说明网络节目表数据的显示方法。
网络节目信息设置为能够显示过去1周内、当前、未来1周内的15天期间的量。在节目信息＜yyyymmdd＞.json中包含一天量的数据。此外，在节目信息＜yyyymmdd＞.json中包含开始时刻。
电视接收机141～150在网络节目表的显示中，在初次显示时将当前节目表尽可能从最新的频道起进行显示。电视接收机141～150记录最后播放的频道。另外，电视接收机141～150在第2次以后将焦点对准在最后播放的频道。
此外，在最后播放的频道为线性频道内容(广播时间为固定的节目)的情况下，电视接收机141～150显示最后播放的频道的PF－ID和service＿id的当前节目。
此外，在最后播放的频道为VOD(Video On Demand：视频点播)的情况下，电视接收机141～150显示最后播放的频道的PF－ID、service＿id、event＿id。在event＿id超过显示范围的15天期间的情况下，电视接收机141～150显示相同频道的最旧的event＿id。
此外，显示的排列顺序由电视接收机141～150的生产者的规格来决定。
另外，网络节目表上的操作方法能够由电视接收机141～150的生产者自由地设定。
另外，如上所述，设置作为服务器的电视网关121，视频平台111～113汇总并发布来自内容服务提供商的内容信息，所述电视网关121接收来自所述视频平台111～113的包含内容信息在内的信息，将接收到的内容信息进行转换以使得电视接收机141～150能够接收该信息，但是在此情况下，存在以下问题。在设置作为服务器的电视网关121的情况下，例如在播放线性频道的内容的情况下，因为广播时间是固定的，所以电视接收机141～150对于作为服务器的电视网关121的访问会集中。因此，关于作为服务器的电视网关121，需要与来自电视接收机141～150的访问的集中峰值匹配地进行设计，成本变高。
因此，在本实施方式的电视接收机141～150中，CPU1109按照应用程序执行，从而作为负荷平均化部1109a而发挥功能。负荷平均化部1109a使得访问电视网关121的访问时间分散，避免向作为服务器的电视网关121的访问集中。以下，说明向电视网关121的 访问集中避免处理。
在线性频道播放时，电视接收机141～150从视频平台111～113的mpd、电视网关121的网络节目表数据用的CDN获取广告信息。此时，电视接收机141～150的负荷平均化部1109a为了避免向电视网关121的访问集中，通过各电视接收机141～150的固有信息，使访问时刻偏移(shift)而动作。
电视接收机141～150从配置在网络节目表数据用的CDN中的配置信息(Conf.json)获取用于计算访问偏移时间(access_shift_time)的基准值。电视接收机141～150在网络节目表的启动时核对配置信息(Conf.json)。电视接收机141～150在配置信息(Conf.json)的基准值已更新的情况下，进行再计算。
访问偏移时间(access_shift_time)是线性频道内容的显示偏移时间。为了避免所有的电视接收机141～150在确定的时刻访问线性频道从而发生向电视网关121的访问集中，访问偏移时间按照每个电视接收机141～150，在一定时间内对节目显示时刻进行偏移。
图30是示出配置信息的峰值偏移键对象(peak_shift Key object)的图。电视接收机141～150获取在电视网关121的网络节目表数据用的CDN中配置的配置信息(Conf.json)。然后，如图30所示，电视接收机141～150在配置信息(Conf.json)的peak_shift键对象中存在的视频的最大时滞(maxdelay)(秒)的范围内执行偏移。例如，电视接收机141～150设定为在10ms左右的范围内执行偏移，使得每个电视接收机141～150在不同的时刻进行访问。
在下文中示出访问偏移时间(access_shift_time)的运算例。
access_shift_time＝(int)(随机数％(D＊100+1))；//10ms
D：最大可延迟时间peak_shift.Video.maxdelay(second)
U：电视接收机具有的固有信息(ex.TV-ID(单独地赋予给电视接收机的识别信息))
对随机数的种子设定U(TV－ID)
而且，向电视网关121的访问时刻由下述式决定。
访问时刻＝S+access_shift_time＊10ms
S：开始时刻
除此之外，电视接收机141～150的负荷平均化部1109a对于网络节目表数据的更新核对时刻也进行偏移，使得不会发生向电视网关121的访问集中。
电视接收机141～150为了定期地核对视频平台111～113是否更新了网络节目表，获取电视网关121的网络节目表数据用的CDN的节目信息更新信息(＜service＿id＞＿lastupdated.json)来进行确认。为了使得这样的对电视网关121的信息获取的访问不会集中，电视接收机141～150进行控制，使得对于每个电视接收机在不同的时间进行访问。
如图30所示，电视接收机141～150在配置信息(Conf.json)的peak_shift键对象中存在的epg的maxdelay(秒)的范围内执行偏移。例如，电视接收机141～150设定为在10ms左右的范围内执行偏移，使得每个电视接收机141～150在不同的时刻访问电视网关121。
在下文中示出网络节目表数据更新核对时刻(epg_update_checktime)的运算例。
epg_update_check_time＝(int)(随机数％(P＊100+1))；//10ms
P：核对间隔peak_shift.epg.maxdelay(second)
U：电视接收机具有的固有信息(ex.TV－ID(单独赋予给电视接收机的识别信息))
对随机数的种子设定U(TV－ID)
而且，电视接收机141～150在每小时、在下述的时刻进行核对。
checktime＝epg.maxdelay＊i＊1000+epg_update_check_time＊10；
checktime(ms)
n＝(60/epg.maxdelay)；
从i＝0至i＜n之间
epg.maxdelay：将一小时以内的60分均等地除算的值
除此之外，电视接收机141～150的负荷平均化部1109a对于日志的收集时刻也进行偏移，使得不会发生向电视网关121的访问集中。
在此，说明日志收集方式。如上所述，电视接收机141～150向电视网关121的日志服务器(firehose stream)上传数据(日志)(步骤4)。
首先，对测定日志向电视网关121的发送接口进行规定。该接口由电视接收机141～150上的应用程序(网络节目表应用程序、以及用于动态图像发布的HTML5应用程序)使用。
向电视网关121的发送时刻取决于服务运用。然而，为了避免访问的集中，在本实施方式中，基于来自电视网关121的时移信息，在各电视接收机141～150中使时间偏移，将多个日志汇总而发送。
首先，说明设备认证。
电视网关121预先制作仅能够向电视网关121的日志服务器(firehose stream)上传数据的IAM用户。电视网关121每12小时生成1次IAM用户的访问秘钥(access key ID和secret access key的组)，并在1天后清除。由此，有效的访问秘钥会始终存在2个。电视网关121将包含生成的访问秘钥在内的、用于向电视网关121的日志服务器(firehose stream)上传数据的信息作为JSON文件(firehose＿params.json)，放在与网络节目表数据相同的场所。
下面示出JSON文件(firehose＿params.json)的例子。此外，访问秘钥记述有效的2个之中新的访问秘钥。
Figure PCTCN2021119176-appb-000002
各电视接收机141～150通过与网络节目表数据获取同样的方法来获取JSON文件(firehose＿params.json)。因为在获取JSON文件(firehose＿params.json)之后保证在"expires_in"中写入的秒数(在此为43200秒、12小时)为有效，所以各电视接收机141～150在该期间内将JSON文件(firehose＿params.json)保持在本地。
电视接收机141～150在需要上传日志时，使用JSON文件(firehose＿params.json)进行认证，向电视网关121的日志服务器(firehose stream)发送日志数据。
此外，在日志数据传送时超过了有效期限的情况下，电视接收机141～150再次从电视网关121获取JSON文件(firehose＿params.json)，并更新信息。
接下来，说明上传的时刻。
各电视接收机141～150并非在日志信息的生成时每次都向电视网关121的日志服务器(firehose stream)进行上传，而是为了实现日志服务器的负荷平均化，将日志信息临时缓冲(Buffering)。
各电视接收机141～150在启动时参照电视网关121在CDN上准备的配置信息(Conf.json)的peak_shift.log要素。
以下，示出配置信息(Conf.json)的peak_shift.log要素的例子。
Figure PCTCN2021119176-appb-000003
Maxdelay是服务器访问分散设定信息，表示应该保持日志的最大时间(秒)。Maxsize是关于数据的保持的设定信息，表示应该保持的日志的最大容量(byte)。这些值并非硬限制(hard limit)，即使超过这些值，电视网关121也接收上传。另一方面，各电视接收机141～150的负荷平均化部1109a在日志的保持时间即将超过maxdelay、或者日志的保持容量即将超过maxsize之中的任一者的情况下，或者在已经超过的情况下，迅速地尝试上传。另外，在由于各电视接收机141～150的本地存储器容量的限制而无法保持日志到接近maxsize为止的情况下，各电视接收机141～150的负荷平均化部1109a尽管可以不管maxsize而进行上传，但是，为了电视网关121的日志服务器(firehose stream)的负荷减轻，尽可能努力使得保持到各自的最大值为止。
此外，在由于通信不良等而未能上传日志的情况下，电视接收机141～150的负荷平均化部1109a超过maxdelay、maxsize的限制地保持日志。电视接收机141～150的负荷平均化部1109a将重试(Retry)设定为指数性缩减(Back off)，不会一味地再发送。
这样，根据本实施方式，因为基于电视接收机具有的固有信息，使服务器访问的访问时间分散，所以能够避免向服务器的访问集中。
此外，电视接收机141～150的负荷平均化部1109a也可以根据服务的状况、访问的状况，变更与数据的保持相关的设定信息、与服务器访问分散设定信息相关的设定信息(配置信息)。由此，能够根据服务的状况、访问的状况来可靠地避免向服务器的访问集中。
图31示出本申请的另一实施例。
本实施例追加了移动终端401～410、以及收看数据保存部451、ID结合信息保存部452、内容推荐信息保存部453、推荐广告选择插入部454、广告服务器455。
在本实施例中，到网络节目表的生成为止，进行与上述同样的动作，但是，电视接收机441～450与移动终端401～410通过各自具有的ID(单独识别数据)来连结。另外，各个电视接收机441～450具有将用户正在收看什么作为收看数据来进行测量的功能，将测量到的收看数据通过TV云431～434上传到电视网关421。
在电视网关421中结合有收看数据保存部451、ID结合信息保存部452。从电视接收机441～450获取到的收看数据经由TV云431～434、电视网关421而被保存在收看数据保存部451。另外，电视接收机441～450和移动终端401～410的ID的结合信息被补充到ID结合信息保存部452。
内容推荐信息保存部453根据收看数据保存部451及ID结合信息保存部452的信息，计算任意一个电视接收机具有什么样的内容的收看倾向，并传达给视频平台411～413。该计算是通过对每次收看的内容的种类的收看时间进行测定等从而实现。
另一方面，推荐广告选择插入部454通过收看数据保存部451及ID结合信息保存部452，计算任意一个电视接收机应当插入什么样的广告，并从广告服务器455获取希望的广告，将广告插入到视频平台411～413的动态图像内容中。
在图32中示出本申请的ID的结构和结合的例子。移动终端401～410具有SP－ID(智能手机ID)501。另一方面，电视接收机441～450具有TV－ID(电视ID)511。SP－ID由作为视频平台的ID的PF－ID、和作为用户的ID的UR－ID构成。TV－ID由作为TV云的ID的TC－ID、和将电视接收机自身作为设备进行表示的DV－ID构成。在ID结合信息保存部452中构成有表示SP－ID与TV－ID的结合信息的表520，电视接收机与移动终端通过ID来形成了连结状态。在此，在表520中"〇"所示的是结合状态，"-"所示的是非结合状态。在此，有可能在一个电视接收机上进行多个移动终端的结合。
在图33中示出ID的结合方式、和分别保存的数据。
电视接收机141和智能手机等移动终端401根据电视接收机上显示的QR编码(注册商标)等，将认证码611向移动终端401传输。该认证码与电视机的对应表被预先保存在TV云431的电视ID保存部603。
认证码611是与单独赋予给电视接收机141的TV-ID对应的具有时间限制的认证码。该认证码611从TV云431送出至电视接收机141。此时，TV云431附加用于向视频平台411连接的地址信息并连同认证码611一起发送到移动终端401。
将认证码611连同移动终端具有的SP－ID一起从智能手机401作为数据612向视频平台411发送，视频平台411以获取到的认证码611以及联动的移动终端401的SP－ID为基础，从持有的顾客数据保存部601获取用户属性，结合SP－ID来作为数据613而向电视网关421发送。
电视网关在获取了认证码、SP－ID、用户属性作为数据613后，基于认证码向TV云431询问，从而获取对应的TV－ID。在此，TV云431对管理下的电视接收机的TV－ID进行管理，在电视ID保存部603中具有TV－ID与认证码的对应表，根据认证码获取任意一个电视接收机是否成为了结合的对象。数据612以及数据613中配置的认证码是与认证码611相同的认证码。
通过这些动作，电视网关421进行TV－ID与SP－ID的结合，并保存在ID结合信息保存部602中。进一步，利用密钥621将TV－ID与SP－ID的结合信息向视频平台411通知。密钥621成为ID结合信息保存部602的数据库的秘钥，通过将密钥621向电视网关421送出，从而能够取出SP－ID和TV－ID及用户属性。
通过以上的动作，利用ID将移动终端和电视接收机连结。此外，在ID结合后，视频平台411利用由电视网关421向视频平台411传输的密钥621，能够开展向成为目标的电视接收机的服务。此外，为了分清与SP－ID的对应，密钥621被保存在顾客数据保存部 601。
此外，图33说明了视频平台411的情况，但是，在视频平台412及413中也进行同样的动作。
在图34中示出结合了ID的情况下的网络节目表。
若TV－ID与SP－ID处于结合状态，则能够根据作为SP－ID的构成要素的PF－ID来判别正在收看的用户是哪个视频平台的顾客，因此，在网络节目表中，将由对应的视频平台构成的频道显示在容易访问的位置。例如，在图34的情况下，在SP－ID501中包含视频平台411的ID的情况下，通过将由视频平台411提供的频道作为初始画面来显示，从而使用户容易选择。另外，通过根据由TV－ID确定的电视接收机的收看数据来推测收看倾向，从而将推荐内容701、702、703同时显示。
这样，由于结合了ID，从而对于用户优先地显示对应的视频平台的内容，由此，容易获得由视频平台提供的服务。
在图35中示出使动态图像内容与Web服务联动的画面的显示例。
在TV－ID511与SP－ID501处于结合状态的情况下，在TV－ID所示的电视接收机上自动地显示与SP－ID501所示的视频平台链接的Web服务画面。由此，用户不仅进行动态图像收看，还能够接受关联信息、EC网站的商品说明等服务。另外，能够使在移动终端上显示的移动应用812与动态图像画面811联动，在通常的遥控器中无法进行的动态图像内容选择方法成为可能。例如，通过在移动终端上触碰移动应用的新闻网站的感兴趣的新闻，从而能够将关联的动态图像内容在电视接收机上播放，能够进行现有技术中没有的内容选择。另一方面，通过在移动应用中显示EC网站，并触碰感兴趣的商品，从而能够获得如观看利用动态图像进行的详细的商品说明等、迄今没有的用户体验。
使用图36详细说明以上的动作。
在视频平台411的动态图像内容与Web网站901链接时，从视频平台411将Web链接信息902输入到电视网关421。另外，除了与现有相同的时间表201、内容元数据202、横幅数据203之外，还将推荐内容数据901输入到电视网关421。
电视网关421将结合的TV-ID501和内容选择数据204、进一步是根据推荐内容数据901制作的推荐元数据911和从Web链接信息获得的链接目标URL向TV云431传输。TV云431与网络节目表一并生成推荐内容显示数据913，并向电视接收机441发送。此时，为了能够与动态图像内容进行链接，与频道、时间信息一并将链接目标URL向电视接收机441设置。电视接收机441基于特定的频道和收看的时间段，根据用户按下链接按钮等，将链接目标URL所示的Web内容显示在电视画面上。
此外，在与移动应用联动的情况下，在从Web网站901将移动应用下载到移动终端401后，将移动应用的操作结果和SP－ID向视频平台411发送。此后，通过从视频平台411将密钥和移动操作向电视网关421发送，从而转换成电视机的共通操作码903，在TV云431中进一步转换成电视机的操作码并控制电视接收机441。密钥能够从作为与SP－ID的对应表的顾客数据保存部601获得。
以上，关于视频平台411进行了说明，但是，关于其它视频平台也是同样的动作。另外，关于TV云431以外的TV云、电视接收机441以外的电视接收机也是同样的动作。
在图37中示出基于本申请的内容的推荐、广告的插入的说明。
将收看数据保存部451及ID结合信息保存部452的信息输入到内容推荐信息保存部 453，计算电视机的收看倾向，对推荐内容、希望的广告的候选进行确定。根据内容推荐信息保存部453的信息，从广告服务器455获取被推荐的广告，视频平台411通过推荐广告选择插入部454的输出，向动态图像内容插入广告。
另一方面，在接收侧广告插入部中，基于内容推荐信息保存部453的信息，从广告服务器455输送希望的广告，通过接收侧广告插入部456的输出，在电视接收机141中向动作内容插入广告。
例如，在视频平台411以组播(Multicast)方式进行动态图像发布的情况下，无法对每个电视接收机插入单独的广告。在此情况下，暂时由视频平台411插入广告并发布了共通的广告之后，在电视接收机侧改写个别地希望的广告。通过该动作，对于个别的电视接收机能够进行像定位销售(targeting)广告那样的与用户匹配的广告显示。
工业实用性
在视频内容的线性分发中，通过对节目构成信息追加VOD信息，在用户观看线性分发的视频内容时，能够在EPG上也显示VOD。由此，能够扩宽收看者的节目选择的宽度。
