具体实施方式
以下，参照附图对实施方式进行说明。
图1是表示包括本发明的实施方式的广告替换装置的可寻址广告系统的构成例的图。
可寻址广告系统包括：广播站(广播信号发送装置)100、广播信号接收装置140、CM发布用服务器120以及管理服务器121。广播信号接收装置140接收广播站(广播信号发送装置)100广播的节目，并且包括本发明的实施方式的广告替换装置。广播站100以及广播信号接收装置140通过网络130与CM发布用服务器120以及管理服务器121连接。
广播站100可以是基站，该基站编排节目并把编排的节目通过广播信号广播给广播信号接收装置140。广播站100也可以被称为广播信号发送装置。
广播站100具有保存并管理CM公司110制作的CM的CM管理服务器101。广播站100将保存在CM管理服务器101中的CM(Commercial Message)插入并编排到广播的节目中途，并且作为一系列的影像流以及音频流通过广播信号广播(发送)给广播信号接收装置140。需要说明的是，CM公司110例如根据基于合同的来自广告主(是指委托CM公司110进行广告制作的客户等)111的委托来制作广告，并且将制作的CM注册到广播站100的CM管理服务器101中。即，在一种实现方式中，CM公司110根据来自基于合同的广告主111的委托来制作CM，并且将制作的CM注册到广播站100的CM管理服务器101中，其中，广告主111是指委托CM公司110进行广告制作的客户等。
此外，广播站100具有与网络130连接的功能，通过网络130与CM发布用服务器120以及管理服务器121连接。
CM发布用服务器120是如下服务器：存储从通过网络130连接的CM管理服务器101发送来的可寻址广告(替换CM)，并根据来自广播信号接收装置140的请求来发布存储的可寻址广告(替换CM)。即，CM发布用服务器120，存储CM管理服务器101发送的替换 CM，并根据来自广播信号接收装置140的请求来发布存储的替换CM，其中，所述CM发布用服务器120通过网络130与CM管理服务器101相连；在一种可行实现方式中，替换CM也可以由CM公司110发送。
管理服务器121是用于提供与广播信号接收装置140接收的节目关联的附加服务的服务器。即，管理服务器121用于提供与广播信号接收装置140接收的节目关联的附加服务。管理服务器121提供的附加服务例如是如下服务：向广播信号接收装置140提供能够置换为可寻址广告(替换CM)的CM时间段，该CM时间段用于广播信号接收装置140将插入节目中途的CM置换为可寻址广告(替换CM)并提供给正在收看某节目的用户。管理服务器121向广播信号接收装置140提供的能够置换为可寻址广告(替换CM)的CM时间段基于从广播站100的CM管理服务器101发送来的可寻址CM时段信息。即，能够置换为替换CM的CM时间段可以基于CM管理服务器101发送来的替换CM时段信息来确定。需要说明的是，替换CM时段信息可以与广播信号一起发送，但是也可以通过管理服务器121和/或CM发布用服务器120发送。
此外，管理服务器121还具有收集广播信号接收装置140的收看历史记录的功能。广播信号接收装置140将插入节目中途的CM置换为可寻址广告(替换CM)的实际情况包含在收看历史记录中并发送。即，广播信号接收装置140可以将插入节目中途的CM被置换为替换CM的实际情况记录在收看历史记录中，并发送给管理服务器121。
广播信号接收装置140是接收从广播站100通过广播信号广播的节目的接收装置。此外，广播信号接收装置140具有与网络130连接的功能，通过网络130与CM发布用服务器120连接。广播信号接收装置140将从CM发布用服务器120发布的可寻址广告(替换CM)保存在所管理的记录介质160中。
此外，为了接收与广播的节目相关的附加服务，广播信号接收装置140通过广播信号接收装置140的(例如)功能设定画面，能够设定与管理服务器121的连接。广播信号接收装置140(例如)通过用户对功能设定画面进行操作，能够将作为与管理服务器121的连接所需要的信息的例如广播信号接收装置140的固有信息、使用广播信号接收装置140的用户的家庭状況(构成家庭的人的性别和年龄)等注册于管理服务器121。由此，管理服务器121(例如)通过广播信号接收装置140的设备ID，能够唯一地识别每台广播信号接收装置140。

解复用器302具有将复用的TLV流分离为数据广播流、影像流、音频流、字幕流以及控制信息的功能。解复用器302将分离的数据广播流、影像流、音频流、数据广播流以及字幕流输入解扰器303、并将作为控制信息的SI信号输入控制信息分析单元309。

控制单元342对广播信号接收装置140的整体动作进行控制。此外，控制单元342在内部具有本发明的实施方式的广告替换装置330，并且对广告替换装置330进行控制。此外，控制单元342还进行作为与网络130的I/F的网络I/F 331、以及作为与外部设备的连接I/F的外部输入I/F 332的控制。
此外，控制单元342还进行如下控制：将能够置换为可寻址广告的时间段的CM置换为广告替换装置330输出的可寻址广告(替换CM)并进行显示。
广告替换装置330进行用于将插入到节目中的广告置换为可寻址广告(替换CM)的处理。
图4A中表示由广告替换装置330进行的，用于将插入到节目中的CM置换为可寻址广告(替换CM)的处理的概要。此外，图4C中表示广告替换装置330的构成的一个例子。此外，图4D中表示广告替换装置的处理的一个例子。
图4A是表示由广告替换装置330进行的，将插入到节目中的CM置换为可寻址广告(替换CM)的处理概要的图。
为了将插入到节目中的CM置换为可寻址广告(替换CM)，广告替换装置330需要获取如下信息：插入到节目中的CM显示的时间、显示的时长等信息，以及替换为插入到节目中的CM并显示的可寻址广告的信息。
广告替换装置330通过在任意时机向提供与节目关联的附加服务的管理服务器121进行请求的方式，能够获取作为插入到节目中的广告的显示开始时间、显示时长等信息(时间段的信息)的CM列表。
此外，广告替换装置330通过在任意时机向CM发布用服务器120进行请求的方式，能够获取可寻址广告(替换CM)并保存在记录介质160中。
广告替换装置330向CM发布用服务器120请求可寻址广告(替换CM)的方法可以是通过广告替换装置330将(例如)可寻址广告(替换CM)的下载请求消息发送给CM发布用服务器120，接收到消息的CM发布用服务器120，将可寻址广告(替换CM)下载到广告替换装置330；也可以是通过广告替换装置330将(例如)包含可寻址广告(替换CM)的 下载开始时刻的下载请求消息，发送给CM发布用服务器120，接收到消息的CM发布用服务器120在到达所述消息所包含的时刻的时候，将可寻址广告(替换CM)下载到广告替换装置330。
广告替换装置330向CM发布用服务器120请求可寻址广告(替换CM)的功能，可以预先包括在广播信号接收装置140中，也可以以广播信号中的控制信息(TLV-SI、MMT-SI)中所包含的信息为基础，由广播信号接收装置140访问特定服务器(未记载)来获取。这样，广播信号接收装置140取得如下功能：以广播信号中的控制信息(TLV-SI、MMTSI)中所包含的信息为基础，广播信号接收装置140通过访问特定服务器(附图中未示出)向CM发布用服务器120请求可寻址广告(替换CM)，作为取得上述功能的方式，例如可以利用被称为数据内容服务的服务，也可以利用除此以外的服务。
图4B是本发明广告替换装置330从管理服务器121获取的CM列表的一个的实施方式的例子。CM列表400包括：作为CM标识符的ID401、作为CM的广播开始时刻的Start_time402，作为广播CM的时长的duration 403、以及表示是否能够替换为可寻址广告的enable404。
例如，410的ID为001002201。ID格式例如前3位001表示频道号，接下来4位0022表示节目的标识符，接下来2位表示包含在由前面4位识别的节目中的CM的标识符。这样的ID可以是任意格式，只要是能够识别在广播信号接收装置140接收的所有频道的所有节目中包含的CM的格式即可。
此外，410的Start_time为20181215201500。Start_time的格式例如前8位20181215表示西历中年月日(yyyymmdd)，接下来6位201500表示时分秒(hhmmss)。
此外，410的duration为15。duration的格式表示显示时间。
此外，410的enable为0。enable的格式(值)在能够替换为可寻址广告(替换CM)时设定为1，不能替换为可寻址广告(替换CM)时设定为0。
此外，CM列表中可以包含CM的产品类型、制造商名称等信息。
图4C是示意性表示本发明的实施方式的广告替换装置330的构成例的图。广告替换装置330包括控制部330-1以及分析部330-2。
控制部330-1通过控制广告替换装置330的整体动作并控制分析部300-2，确定用于替换包含在广播节目中的CM的可寻址广告(替换CM)，并将所述可寻址广告(替换CM)显示于广播信号接收装置140的显示单元350。
此外，控制部330-1从CM发布用服务器120获取作为替换CM的候选的多个可寻址广告，并将所述个可寻址广告保存在记录介质160中，并且从管理服务器121获取CM列表并将所述CM列表保存在记录介质160中。
分析部330-2对保存在记录介质160中的CM列表进行分析，判断记载在CM列表中的CM是否能够替换为可寻址广告(替换CM)。
图4D是表示本发明的实施方式的广告替换装置330进行的、替换为可寻址广告(替换CM)的处理的一个例子的处理流程。
如果广播信号接收装置140开始接收广播节目，则广告替换装置330开始用于将包含在被接收到的节目中的CM替换为可寻址广告的处理(S400)。
广告替换装置330的控制部330-1访问管理服务器121，确认在管理服务器121中是 否存在更新的CM列表(S401)。
如果确认的结果为存在更新的CM列表时(S402的“是”)，控制部330-1从管理服务器121获取并保存更新的CM列表(S403)。
如果确认的结果为不存在更新的CM列表时(S402的“否”)，直到在管理服务器121中新出现更新的CM列表为止，控制部330-1连续或一边等待一定时间一边反复进行确认处理(S401)。即，如果不存在更新的CM列表，那么控制部330-1持续进行确认处理(S401)，或者以一定时间为间隔，周期性进行确认处理(S401)，直到在管理服务器121中新出现更新的CM列表为止。
接下来，控制部330-1从保存的CM列表中获取在广播信号接收装置140的显示单元350显示的节目、即包括在收看者正在收看的节目中的CM的start_time，并确认当前时刻是否到达start_time(S404)。即，控制部330-1从已被保存的CM列表中，获取在广播信号接收装置140的显示单元350显示的节目(即收看者正在收看的节目)中包含的CM的start_time，并确认当前时刻是否到达start_time(S404)。
如果确认(S404)的结果为当前时刻到达start_time时(S405的“是”)，控制部330-1向分析部330-2询问并确认是否存在代替插入到节目中的CM而能够显示的置换用CM(可寻址广告)(S406)。
当向分析部330-2询问并确认(S406)的结果为存在替换用CM(可寻址广告)时(S407的“是”)，控制部330-1从分析部330-2获取对应的替换用CM(可寻址广告)来代替插入到节目中的CM并显示于显示单元350(S408)。
当向分析部330-2询问并确认(S406)的结果为不存在替换用CM(可寻址广告)时(S407的“否”)，使插入到节目中的CM保持原样显示于显示单元350(S409)。
如果确认(S404)的结果为当前时刻未到达start_time时(S405的“否”)，直到当前时刻到达start_time为止，控制部330-1反复进行S404的确认处理。即，如果当前时刻未到达start_time，控制部330-1反复进行S404的确认处理，直到当前时刻到达start_time为止。
不存在对应的替换用CM(可寻址广告)可以是指例如不存在与CM列表400中记载的某个CM的duration 403一致的替换用CM(可寻址广告)的情况、或者在CM列表400中不存在enable为1(能够替换)的CM的情况。
此外，也可以是如下情况：分析部330-2例如具有推定收看显示单元350正在显示的节目的收看者的功能(未图示)，并且判断为不存在最适合于该推定的收看者的CM。
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)。能够根据start_time和duration来计算显示结束时刻。
如果确认的结果(S410)为当前时刻到达CM的显示结束时刻时(S411的“是”)，控制部330-1向分析部330-2询问并确认是否存在接着到达了显示结束时刻的CM继续显示的CM(S412)。
当向分析部330-2询问并确认(S412)的结果为存在接着到达了显示结束时刻的CM继续显示的CM时(S413的“是”)，控制部330-1返回S406的处理，询问是否存在代替到达了显示结束时刻的CM的下一个CM而能够显示的替换用CM(可寻址广告)(S406)。
当向分析部330-2询问并确认(S412)的结果为不存在接着到达了显示结束时刻的CM 继续显示的CM时(S413的“否”)，控制部330-1向分析部330-2询问并确认在显示单元350正在显示的节目中在以后时机是否显示CM(S414)。
当向分析部330-2询问并确认(S414)的结果为在以后的时机显示CM时(S415的“是”)，控制部330-1返回S405的处理，对在以后的时机显示的CM继续进行是否存在替换用CM的处理。即，对后续显示的CM是否存在替换用CM的继续进行处理。
当向分析部330-2询问并确认(S414)的结果为在以后的时机不显示CM时(S415的“否”)，控制部330-1返回S402的处理，对插入到新的节目中的CM继续进行是否存在替换用CM的处理。即，对插入到新的节目中的CM是否存在替换用CM的继续进行处理。
这样，控制部330-1通过参照CM列表400，确认插入到广播的节目中的所有CM是否存在替换用CM(可寻址广告)。
需要说明的是，如果以图4B所示CM列表400为例，则S412的是否存在继续显示的CM的确认是对412的信息的CM确认413的信息的CM，即，S412中确认是否存在继续显示的CM，是指在确认了412所示信息的所对应的CM的基础上，进一步确认413所示信息所对应的CM是否存在。如ID号所示，412所示的信息的CM以及413所述的信息的CM是在同一节目中连续(继续)广播的CM。
此外，如果以图4B所示CM列表400为例，则S414的在以后的时机是否显示CM的确认是在414的信息的CM的显示结束的时点确认415的信息的CM。如ID号所示，414的信息的CM以及415的信息的CM是在同一节目中广播的CM，415的信息的CM是与414的信息的CM以不连续(继续)的方式广播的CM。即，S414中确认在以后的时机是否显示CM，是指在414所示信息所对应的CM的显示结束的时点确认415所示信息所对应的CM。
以上只是利用附图说明了包括本发明的实施方式的广告替换装置330以及广告替换装置330的可寻址广告系统的例子，但是本发明并不仅限于上述例子。
在图1所示的可寻址广告系统的构成例中，以如下情况为例进行了说明：广播站(广播信号发送装置)100发送以MMT/TLV方式复用的广播波、广播信号接收装置140接收以MMT/TLV方式复用的广播波，但是也可以是广播波以MPEG-2方式复用的情况。或者在图1所示的可寻址广告系统的构成例中，广播站(广播信号发送装置)100可以通过网络130将节目内容发布给广播信号接收装置140。其中，广播波也可以被称为广播信号。
此外，在图1所示的可寻址广告系统的构成例中是仅包括一个广播信号接收装置140作为例子，但是也可以包括多个。在这种情况下，管理服务器121可以利用各广播信号接收装置140所具有的设备ID，识别并管理多个广播信号接收装置140。
此外，说明了本发明的实施方式的CM替换装置330包括在广播信号接收装置140中，但是也可以包括在能够与广播信号接收装置140通信且通过其设备ID能够识别各广播信号接收装置140的单独部件中。例如，该单独部件可以是管理服务器121。
广告替换装置330包括在单独部件中时，单独部件中的广告替换装置330通过网络130，通过广播信号接收装置140的记录介质160中保存的可寻址广告(替换CM)广播的时长信息、以及从管理服务器121获取的CM列表，进行图4D所示的处理，如S408所示，使显示单元350显示的处理只要通过网络130向广播信号接收装置140发出显示指示即可。
如上所述，本发明的实施方式的广告替换装置330基于获取的CM列表记载的CM的信息，对显示于显示单元350的节目的所有CM判定是否能够替换为可寻址广告(替换CM)， 对于能够替换的CM，能够替换为可寻址广告(替换CM)并显示于显示单元350。
对本发明的一些实施方式进行了说明，但这些实施方式只是作为示例提示的，并不旨在限定发明的范围。这些新的实施方式能够通过其他各种方式来实施，并在不脱离发明的主旨的范围内，能够进行各种省略、替换和变更。这些实施方式及其变形包含在发明的范围和主旨中，并包含在权利要求书记载的发明及其均等的范围内。此外，在权利要求的各构成要素中，将构成要素分割表现的情况、或组合多个表现的情况、或将它们组合表现的情况均属于本发明的范畴。此外，将权利要求作为控制逻辑表现的情况、作为包括使计算机执行的指令的程序表现的情况、以及作为描述所述指令的计算机可读记录介质表现的情况也应用了本发明的装置。此外，对所使用的名称、术语也没有限定，只要是在实质上相同的内容或相同的宗旨，其他表现也包含在本发明中。
