图4A是表示广告替换处理部330进行的、用于将向节目插入的CM置换为 可寻址广告(替换CM)的处理的概要的图。
广告替换处理部330为了将向节目插入的CM置换为可寻址广告(替换CM)，需要获取CM的显示开始的时间、显示的长度等信息(CM时间段信息)作为向节目插入的CM的信息，而且获取显示可寻址广告的长度的信息等作为替换为向节目插入的CM进行显示的可寻址广告的信息。
广告替换处理部330能够经由控制信息解析机构309获取SI信号所包含的CM时间段信息。
另外，广告替换处理部330能够对于CM发布用服务器120在任意的时机要求可寻址广告(替换CM)。广告替换处理部330能够接收对于发送的要求进行响应而从CM发布用服务器120传送来的可寻址广告(替换CM)及显示可寻址广告的长度的信息等属性信息，并且能够保存于记录介质160。
广告替换处理部330对CM发布用服务器120要求可寻址广告(替换CM)的方法可以是广告替换处理部330例如将可寻址广告(替换CM)的下载要求消息向CM发布用服务器120发送，由此接收到消息的CM发布用服务器120将可寻址广告(替换CM)向广告替换处理部330下载，也可以是广告替换处理部330例如将包含可寻址广告(替换CM)的下载开始时刻在内的下载要求消息向CM发布用服务器120发送，由此接收到消息的CM发布用服务器120在到达消息所包含的时刻的时机，将可寻址广告(替换CM)向广告替换处理部330下载。
广告替换处理部330对CM发布用服务器120要求可寻址广告(替换CM)的功能可以预先设定于广播信号接收装置140之中，也可以是以广播信号所包含的控制信息(TLV-SI或MMT-SI)所包含的信息为基础，广播信号接收装置140访问特定的服务器(未记载)来获取。这样，作为广播信号接收装置140以广播信号所包含的控制信息(TLV-SI、MMT-SI)所包含的信息为基础，广播信号接收装置140访问特定的服务器(未记载)并且获取对CM发布用服务器120要求可寻址广告(替换CM)的功能的方式，例如可以使用称为数据内容服务的服务，也可以使用除此以外的服务。

图4C是概略性地表示本发明的实施方式的广告替换处理部330的构成例的 图。广告替换处理部330包括控制部330-1和解析部330-2。
控制部330-1控制广告替换处理部330的整体的动作，并控制解析部300-2，由此决定对广播节目所包含的CM进行替换的可寻址广告(替换CM)，并使决定的可寻址广告(替换CM)显示于广播信号接收装置140的显示机构350。
另外，控制部330-1从CM发布用服务器120获取替换CM的候补即多个可寻址广告并保存于记录介质160。而且，控制部330-1根据获取到的CM时间段信息，制作CM列表并保存于记录介质160。图4D示出控制部330-1制作的CM列表的一例。

例如450的Event_ID451为22，CM_ID452为01。而且，450的Start_time为20181215201500。Start_time的格式为例如开头的8位的20181215以西历表示年月日(yyyymmdd)，接下来的6位的201500表示时分秒(hhmmss)。而且，450的duration为15。而且，450的enable为0。CM列表除了图4D记载以外，也可以包含CM名等。
图4E是表示本发明的实施方式的广告替换处理部330进行的替换为可寻址 广告(替换CM)的处理的一例的处理流程。
当广播信号接收装置140开始接收广播节目时，广告替换处理部330开始用于将接收到的节目所包含的CM替换为可寻址广告的处理(S400)。
广告替换处理部330的控制部330-1访问保存有CM列表的记录介质160，确认是否存在更新后的CM列表(S401)。
在确认的结果是更新后的CM列表存在的情况下(S402为“是”)，控制部330-1从记录介质160获取更新后的CM列表并保持(S403)。
在确认的结果是更新后的CM列表不存在的情况下(S402为“否”)，控制部330-1连续地或者等待一定时间地反复进行确认处理(S401)直至在记录介质160保存更新后的CM列表为止。
接下来，控制部330-1从保持的CM列表之中，获取广播信号接收装置140的显示机构350显示的节目、即收看者收看的节目所包含的CM的start_time，进行当前时刻是否到达start_time的确认(S404)。
在确认(S404)的结果是当前时刻到达start_time的情况下(S405为“是”)，控制部330-1向解析部330-2询问并确认是否存在取代向显示机构350显示的节目插入的CM而能够显示的置换用CM(可寻址广告)(S406)。
在向解析部330-2询问并确认(S406)的结果是置换用CM(可寻址广告)存在的情况下(S407为“是”)，控制部330-1从解析部330-2获取对应的置换用CM(可寻址广告)，取代向节目插入的CM而显示于显示机构350(S408)。
在向解析部330-2询问并确认(S406)的结果是置换用CM(可寻址广告)不存在的情况下(S407为“否”)，将向节目插入的CM原样地显示于显示机构350(S409)。
在确认(S404)的结果是当前时刻未到达start_time的情况下(S405为“否”)，控制部330-1反复进行S404的确认处理直至当前时刻到达start_time为止。
对应的置换用CM(可寻址广告)不存在是指例如可以是与CM列表450记载的某CM的duration403一致的替换用CM(可寻址广告)不存在的情况、 或enable为1(能够置换)的CM在CM列表400之中不存在的情况。
另外，可以是如下情况：解析部330-2例如具有推断正在收看显示机构350显示中的节目的收看者的功能(未图示)，并判断为对于该推断出的收看者而言最佳的CM不存在。
接下来，控制部330-1确认当前时刻是否到达CM的显示结束时刻(S410)。显示结束时刻可以根据start_time和duration来算出。
在确认(S410)的结果是当前时刻到达CM的显示结束时刻的情况下(S411为“是”)，控制部330-1向解析部330-2询问并确认是否存在在到达显示结束时刻的CM之后继续显示的CM(S412)。
在向解析部330-2询问并确认(S412)的结果是存在在到达显示结束时刻的CM之后继续显示的CM的情况下(S413为“是”)，控制部330-1返回S406的处理，进行是否存在取代已到达显示结束时刻的CM的接下来的CM而能够显示的替换用CM(可寻址广告)的询问(S406)。
在向解析部330-2询问并确认(S412)的结果是不存在在到达显示结束时刻的CM之后继续显示的CM的情况下(S413为“否”)，控制部330-1向解析部330-2询问并确认是否在显示机构350显示中的节目中、在以后的时机显示CM(S414)。
在向解析部330-2询问并确认(S414)的结果是在以后的时机显示CM的情况下(S415为“是”)，控制部330-1返回S405的处理，对于在以后的时机显示的CM继续进行替换用的CM是否存在的处理。
在向解析部330-2询问并确认(S414)的结果是在以后的时机不显示CM的情况下(S415为“否”)，控制部330-1返回S402的处理，对于向新的节目插入的CM继续进行替换用的CM是否存在的处理。
这样，控制部330-1通过参照CM列表400，对于向进行广播的节目插入的全部的CM进行替换用CM(可寻址广告)是否存在的确认。
需要说明的是，S412的接续显示的CM是否存在的确认如果以图4B所示 的CM列表400为例，则是对于412的信息的CM来确认413的信息的CM。462的信息的CM和463的信息的CM如通过Event_ID编号来表示那样在同一节目中，是如Start_time及duration所示连续(继续)广播的CM。
另外，S414的是否在以后的时机显示CM的确认如果以图4B所示的CM列表400为例，则是在414的信息的CM的显示结束的时点确认415的信息的CM。414的信息的CM及415的信息的CM如Event_ID编号所示是在同一节目中广播的CM，415的信息的CM如Start_time及duration所示是与414的信息的CM不连续(不继续)地广播的CM。
需要说明的是，图4E所示的处理流程提示了根据EIT、CM时间段信息描述符而制作CM列表来进行处理的流程，但是也可以将EIT、CM时间段信息描述符的表格直接向记录介质160等保持，直接一边参照一边进行动作。
虽然使用附图说明了本发明的实施方式的广告替换处理部330及包含广告替换处理部330的可寻址广告系统的例子，但是没有限定为上述的例子。
在图1所示的可寻址广告系统的构成例中，以广播电台(广播信号发送装置)100发送通过MMT-TLV方式复用的广播波且广播信号接收装置140接收通过MMT-TLV方式复用的广播波的情况为例进行了说明，但是广播波可以是通过MPEG-2方式复用的广播波。在该情况下，CM时间段信息描述符可以是配置于EIT(Event Information Table)的描述符之一。或者，在图1所示的可寻址广告系统的构成例中，广播电台(广播信号发送装置)100可以经由网络130将节目内容向广播信号接收装置140发布。
另外，在图1所示的可寻址广告系统的构成例中，是仅包含1个广播信号接收装置140的例子，但也可以包含多个。此外，可寻址广告系统可以包含管理服务器，该管理服务器通过广播信号接收装置140分别具有的设备ID，经由网络130管理广播信号接收装置140，对于各个广播信号接收装置140提供独自的服务的管理服务器。
如以上所述，包含本发明的实施方式的广告替换处理部330的广播信号接 收装置140基于广播信号所包含的CM时间段信息描述符的CM时间段信息，对于显示机构350显示的节目的全部CM判断是否能够替换为可寻址广告(替换CM)，对于能够替换的CM，可以替换为可寻址广告(替换CM)而显示于显示机构350。
由此，本发明的实施方式的广播信号接收装置仅通过广播信号所包含的CM时间段信息，根据向节目插入的CM，能够适当地替换为可寻址广告(替换CM)。
虽然说明了本发明的若干的实施方式，但是这些实施方式是作为例子而提示的方式，没有限定发明的范围。这些新的实施方式能够以其他的各种方式实施，在不脱离发明的主旨的范围内，能够进行各种省略、置换、变更。这些实施方式或其变形包含于发明的范围或主旨，并包含于权利要求书记载的发明及其等同的范围。此外，在权利要求项的各构成要素中，将构成要素分割表现的情况、或将多个合并表现的情况、或将它们组合表现的情况也是本发明的范畴。而且将权利要求项表现作为控制逻辑的情况、表现作为包含使计算机执行的指令的程序的情况、及表现作为记载有前述指令的计算机可读取的记录介质的情况下，也适用本发明的装置。而且，关于使用的名称或用语也没有限定，即便是其他的表现只要实质上为同一内容、相同意旨，就包含于本发明。
