解码后的影像数据及字幕数据由合成器5501合成而向显示器5002输入。 解码后的语音数据经由合成器5502向扬声器系统5003输入。
另外，由多路分配器5303分离的数据播放信号由数据播放接收处理部5330接收，向数据播放引擎5315输入。通过数据播放传送来的显示用信号向合成器5501输入而显示于显示器5002。
作为对接收机5000的整体性的动作进行控制的机构，设有综合控制器5200。综合控制器5200具有应用程序控制部5201、安全管理部5202。应用程序控制部5201基于应用程序控制信息所包含的各种信息、控制信息，来控制接收机5000的各模块。
另外，综合控制器5200当从用户经由GUI5220等而指定录像对象的广播节目等时，使用规定的内容保护方式将影像数据、字幕数据及语音数据等加密，转换成规定的记录格式之后，记录于记录介质5001，从而进行广播节目的录像。
另外，综合控制器5200当从用户经由GUI5220等而指定播放对象的录像节目等时，如下进行录像节目的播放：将记录介质5001所记录的数字的影像数据、字幕数据及语音数据等读出，并且向影像解码器5311、声音解码器5312及字幕解码器5313供给。
安全管理部5202管理应用程序，实现安全功能。例如，安全管理部5202具有应用程序认证功能，将认证后的应用程序作为管理应用程序来处理。而且，安全管理部5202具备访问控制功能、提示功能、实施(Enforcement)功能、以广播之外的管理应用程序为对象的撤销(Revocation)功能等。需要说明的是，在此将安全管理部5202的控制与应用程序控制部5201的控制分开记载，但是也可以不分开而作为一个管理部进行控制。
访问控制功能使被许可利用的应用程序能够参照影像、语音、元数据SI信息等的广播资源、接收机5000的影像语音输出、网络接口等的接收机资源。而且，根据应用程序的安全等级来限制能够访问的接收机API(Application Programming Interface)。

在此，在记录介质5001中保存有从上述的CM发布用服务器4000获取到的可寻址CM。综合控制器5200向记录介质5001下载CM发布用服务器4000持有的可寻址CM中的、接收机5000的收看者喜欢的可寻址CM。CM发布用服务器4000持有的可寻址CM被分成带有表示收看者的喜好的“车”、“体育”、“旅行”等的标签(Tag)的多个组。综合控制器5200基于从管理服务器3000获取到的、与接收机5000的收看者的喜好相关的信息，下载被赋予了与收看者的喜好相符的标签的可寻址CM组。
下载到记录介质5001的可寻址CM暂时保存于DRAM处理部5104。然后，可寻址CM由多路分配器5303分离，影像流由影像解码器5311解码，语音流由语音解码器5312解码，字幕流由字幕解码器5313解码。
解码后的影像数据及字幕数据由合成器5501合成而向显示器5002输入。解码后的语音数据经由合成器5502向扬声器系统5003输入。由此，可寻址CM通过显示器5002及扬声器系统5003输出。
应用程序控制部5201基于与可寻址CM的播放相关的应用程序控制信息，对接收机5000的各模块进行控制，在规定的可寻址CM段中播放可寻址CM。
(管理服务器的构成例)
图5是表示实施方式1的管理服务器3000的功能部的构成例的图。如图5 所示，管理服务器3000具备收看历史获取部3110、收看历史解析部3120、CM信息生成部3210、CM信息发送部3220、用户属性存储部3310、收看历史存储部3320及CM信息存储部3330。
收看历史获取部3110从管理服务器3000管理的接收机5000获取接收机5000的收看者的收看历史。收看历史例如包括收看直播的广播节目的类别及播放时间段等的收看历史、被录像的广播节目的类别及播放时间段等的录像历史、以及播放的录像节目的类别及播放时间等的播放历史等信息。收看历史获取部3110将上述的收看历史的信息作为广播节目收看历史3321、录像/播放历史3322等而保存于收看历史存储部3320。
收看历史解析部3120对接收机5000的收看者的喜好等进行解析。这样的解析使用在收看历史存储部3320保存的广播节目收看历史3321、录像/播放历史3322等信息、及在用户属性存储部3310保存的性别信息3311、年龄层信息3312等信息。性别信息3311及年龄层信息3312是关于拥有接收机5000的家庭的构成人员的属性信息。这样的属性信息例如通过购入接收机5000时的事前的问卷调查等，经由接收机5000能够从收看者那里得到。通过这样的解析，从收看者的收看倾向能得到喜欢车、喜欢体育、喜欢旅行这样的信息。
CM信息生成部3210根据通过收看历史解析部3120的解析而推定的喜好等的信息，来决定与该接收机5000的收看者的喜好相符的可寻址CM。
例如，收看历史解析部3120判定为：在播放广播节目“a”的关于商品“n”的面向大众CM的可寻址CM段中，适合对该接收机5000的收看者提供关于商品“m”的可寻址CM等。
另外，除此之外，还可以考虑如下情况等：面向有小孩的家庭的家长层，在认为家长收看的晚上的时间段的广播节目中设定的可寻址CM段中，提供与小孩相关的商品的可寻址CM。
CM信息生成部3210生成包含与该接收机5000的收看者的喜好相符的可寻址CM的信息在内的CM信息。这样的CM信息可以按照该家庭的各构成人员 来生成，CM信息生成部3210将这样的CM信息作为例如面向用户(A)的CM信息(A)3331、面向用户(B)的CM信息(B)3332……等而保存于CM信息存储部3330。
CM信息发送部3220将保存到CM信息存储部3330的CM信息(A)3331、CM信息(B)3332……等向接收机5000发送。
需要说明的是，管理服务器3000的上述列举的各功能部只不过为一例。可以将管理服务器3000的规定的功能部分割成更细分化的多个功能部。而且，可以将管理服务器3000的上述列举的若干的功能部合并成为一个功能部。而且，管理服务器3000可以不用具有上述列举的全部功能部，而且，可以具有上述列举的功能部以外的功能部。
(接收机的构成例)
图6是表示实施方式1的接收机5000的功能部的构成例的图。如图6所示，接收机5000具备操作接收部5610、CM信息获取部5620、广播接收部5710、动态图像内容接收部5720、直播收看处理部5730、录像处理部5740、播放处理部5750、CM获取部5910、CM替换部5920、录像节目存储部5810及CM存储部5820。
操作接收部5610接收来自用户的直播收看操作、录像操作、录像预约操作及播放操作等各种操作。由用户进行的性别信息3311、年龄层信息3312等属性信息的输入也经由操作接收部5610进行。
CM信息获取部5620获取管理服务器3000生成的CM信息(A)3331、CM信息(B)3332……等。
CM获取部5910基于CM信息(A)3331、CM信息(B)3332……等，从CM发布用服务器4000获取与该接收机5000的收看者的喜好等相符的可寻址CM，作为CM(A)5821、CM(B)5822……等而保存于CM存储部5820。如上所述，CM存储部5820例如通过暂时记录高速缓存的DRAM处理部5104等硬件结构实现，暂时保存CM(A)5821、CM(B)5822……等。由此，CM(A)5821、CM(B)5822……等能够在不会被用户意识到的情况下从CM发布用服务器4000被下载并根据需 要进行更新。
CM替换部5920将广播节目所包含的CM中的、可寻址CM段的CM替换为在CM存储部5820保存的CM(A)5821、CM(B)5822……等的任意的可寻址CM。
广播接收部5710接收来自广播电台1000的广播信号。
动态图像内容接收部5720例如经由互联网等网络，接收来自动态图像内容发布服务器等的动态图像内容。动态图像内容发布服务器是例如视频点播那样发布视频内容等动态图像内容的服务器。
直播收看处理部5730进行广播节目及动态图像内容等的直播收看的处理。直播收看是指例如将在该时点播放中的广播节目实时地显示的情况。
录像处理部5740按照来自用户的录像操作及录像预约操作，进行包含可寻址CM等在内的广播节目的录像的处理。录像处理部5740将录像节目(A)5811、录像节目(B)5812……保存于录像节目存储部5810。
播放处理部5750按照来自用户的播放操作，从录像节目存储部5810读出录像节目(A)5811、录像节目(B)5812……进行播放的处理。
需要说明的是，接收机5000的上述列举的各功能部只不过为一例。可以将接收机5000的规定的功能部分割成更细分化的多个功能部。而且，可以将接收机5000的上述列举的若干的功能部合并成为一个功能部。而且，接收机5000可以不用具有上述列举的全部功能部，而且，可以具有上述列举的功能部以外的功能部。
(接收机的功能例)
接下来，使用图7，说明实施方式1的接收机5000的功能例。图7是说明实施方式1的接收机5000的功能例的图。
在图7的例子中，将通过广播电台1000按照正篇PRGa、面向大众CMx、正篇PRGb的顺序播放的内容通过接收机5000替换为可寻址CM(aCM)y进行录像。而且，面向大众CMx设为以可寻址CM段被播放的CM。
接收机5000的CM获取部5910预先获取与收看者的喜好相符的可寻址CMy。
CM替换部5920当广播节目的正篇PRGa开始时，进行CM替换的准备，在面向大众CMx的播放中，将面向大众CMx替换为可寻址CMy进行播放。由此，在接收机5000的直播收看中，针对面向大众CMx覆盖显示可寻址CMy。可寻址CMy与面向大众CMx的CM段被设定为相同长度，因此当可寻址CMy的播放结束时，面向大众CMx的CM段也结束，广播节目的正篇PRGb开始。
CM替换部5920进行的CM的替换具体而言例如以下那样进行。当广播节目的正篇PRGa开始时，在接收机5000中，与可寻址CMy的发布相关的混合广播应用程序以非显示状态起动。当接收到包含于广播信号并预告面向大众CMx的开始的事件消息时，混合广播应用程序将透明画面等与播放动态图像重叠显示。由此，不会妨碍广播节目的正篇PRGa的收看。当接收到广播信号包含的表示CM开始的事件消息时，获取到的可寻址CMy与播放中的面向大众CMx重叠地被播放。在可寻址CMy的播放结束的时刻，接收到广播信号包含的表示CM结束的事件消息，广播节目的正篇PRGb开始。
另一方面，录像处理部5740当广播节目的正篇PRGa开始时，开始录像的处理。而且，录像处理部5740不是对播放中的面向大众CMx而是对替换后的可寻址CMy进行录像。而且，录像处理部5740在可寻址CMy的播放结束后也继续录像，当广播节目的正篇PRGb结束时，结束录像的处理。由此，生成按照正篇PRGa、可寻址CMy、正篇PRGb的顺序被录像的内容，例如录像节目5811。
(接收机中的录像播放处理)
接下来，使用图8，说明实施方式1的接收机5000的作为接收处理的录像播放处理的例子。图8是表示实施方式1的接收机5000的录像播放处理的顺序的一例的流程图。
如图8所示，CM获取部5910从CM发布用服务器4000获取与收看者的喜 好相符的可寻址CM，作为CM(A)5821、CM(B)5822……等而保存于CM存储部5820(步骤S101)。
当用户进行录像操作或录像预约、且录像对象的广播节目开始时，录像处理部5740开始广播节目的录像(步骤S102)。
CM替换部5920当检测到可寻址CM段的播放开始时，将以可寻址CM段被播放的面向大众CM替换为可寻址CM(步骤S103)。
伴随着可寻址CM的播放结束而可寻址CM段的播放也结束(步骤S104)。
当录像对象的广播节目结束时，录像处理部5740结束录像(步骤S105)。
通过以上所述，实施方式1的接收机5000进行的录像播放处理结束。
近年来，收集经由电视或互联网的内容的收看历史，进行收看者的喜好或购买行动等的解析。作为有效利用这样的解析结果的一个方法，存在面向特定的收看者的可寻址CM发布的需求。
在实施方式1的系统中，具有在通常的广播节目内的CM段对可寻址CM进行替换而切换显示的CM替换部5920。并且，录像处理部5740对替换后的可寻址CM原封不动地录像。由此，不仅仅是发布可寻址CM还能够对可寻址CM进行录像。
在实施方式1的系统中，替换为根据该接收机5000的收看历史及收看者的属性等而解析出的可寻址CM。由此，能够替换为与该接收机5000的收看者的喜好相符的可寻址CM而进行录像。
需要说明的是，在实施方式1的系统中，可寻址CM段的开始、结束除了CM替换部5920接收并检测来自广播电台1000的事件消息之外，也可以基于可寻址CM段的播放时刻等信息来检测可寻址CM段的开始、结束。或者，可以基于广播内容的图像识别等来检测可寻址CM段的开始、结束。
(变形例)
以下，参照附图，详细说明实施方式1的变形例。变形例的系统是录像的顺序未必成为播放顺序的情况的例子。在这样的变形例的系统中，例如，能够 应对在录像对象的广播节目的开始时，预定替换的可寻址CM还未获取的情况等。
图9是说明实施方式1的变形例的接收机5000的功能例的图。
如图9(a)所示，接收机5000的录像处理部5740当广播节目的正篇PRGa开始时，开始录像的处理。
如图9(b)所示，CM替换部5920例如在预定替换的可寻址CMy还未获取的状态的情况下，当检测到可寻址CM段的播放开始时，在该CM段的开始位置设立标志F。
如图9(c)所示，录像处理部5740在可寻址CMy的播放未开始的情况下，在该CM段的播放中，可以暂时停止录像也可以继续录像。
另一方面，CM获取部5910当表示可寻址CM段的开始位置的标志F设立时，或者根据来自CM替换部5920的通知，从CM发布用服务器4000中开始下载预定替换的可寻址CMy。
如图9(d)所示，CM替换部5920在可寻址CMy的下载结束后，例如在广播节目的正篇PRGb的结束时的时刻等，使可寻址CMy录像到录像处理部5740。由此，例如生成录像节目5812。
即，在图9的例子中，录像处理部5740按照正篇PRGa、正篇PRGb、可寻址CMy的顺序进行录像。
即使在该情况下，在播放该录像节目5812时，播放处理部5750也根据表示可寻址CM段的开始位置的标志F，按照正篇PRGa、可寻址CMy、正篇PRGb的顺序播放。
图10是表示实施方式1的变形例的接收机5000的录像播放处理的顺序的一例的流程图。在图10的例子中，在录像对象的广播节目的接收开始时点，预定替换的可寻址CM还未获取。
如图10所示，当用户进行录像操作或录像预约、且录像对象的广播节目开始时，录像处理部5740开始广播节目的录像(步骤S201)。
CM替换部5920当检测到可寻址CM段的播放开始时，设立表示可寻址CM段的开始位置的标志(步骤S202)。
CM替换部5920检测可寻址CM段的播放结束(步骤S203)。
录像对象的广播节目结束(步骤S204)。
另一方面，CM获取部5910开始从CM发布用服务器4000获取在该广播节目包含的可寻址CM段中预定替换的可寻址CM，CM替换部5920等待直至获取可寻址CM为止(步骤S205：否)。
当获取可寻址CM时(步骤S205：是)，CM替换部5920使获取到的可寻址CM在规定的时刻由录像处理部5740录像(步骤S206)。
录像处理部5740等待广播节目的结束(步骤S204)或可寻址CM的录像结束(步骤S206)中的任一晚的一方而结束录像(步骤S207)。
这样，步骤S205～S206例如在步骤S203～S207之间，与录像对象的广播节目的录像并行地推进。
通过以上所述，变形例的接收机5000的录像播放处理结束。
在实施方式1的变形例的系统中，录像处理部5740的录像顺序可以不是播放顺序，播放处理部5750无论录像顺序如何都按照正规的顺序进行播放。由此，例如，在录像对象的播放接收时点即使未获取应替换的可寻址CM，也能够之后进行下载并插入。
[实施方式2]
以下，参照附图，详细说明实施方式2。在实施方式2的系统中，对于分别面向多个用户的多个可寻址CM进行录像。
(接收机的构成例)
图11是表示实施方式2的接收机5000a的功能部的构成例的图。如图11所示，接收机5000a除了实施方式1的接收机5000的结构之外，还具备用户识别部5630及用户信息存储部5830。
用户识别部5630对拥有接收机5000a的家庭的构成人员进行识别。用户识 别部5630例如具备相机功能，通过图像识别等对操作接收机5000a的用户进行识别。在接收机5000a能够接收基于语音的操作指示时等，用户识别部5630可以从语音信息识别用户。用户识别部5630除此之外，也可以使管理服务器3000具有的性别信息3311及年龄层信息3312等与用户相关的属性信息用于帮助用户识别。用户识别部5630也可以从操作接收部5610得到基于用户自身的信息。
用户识别部5630将识别出的关于各用户的信息作为用户信息(A)5831、用户信息(B)5832……等保存于用户信息存储部5830。而且，通过与各用户的接收机5000的操作历史、收看历史等建立联系，从而用户信息(A)5831、用户信息(B)5832……等包括各用户的喜好、面向各用户的可寻址CM等信息。这些信息基于管理服务器3000的解析结果。
具体而言，例如，用户信息(A)5831是与该家庭的父亲相关的信息，包含作为父亲的喜好而喜欢车的情况、作为面向父亲的可寻址CM而与车相关的CM合适的情况等信息。而且，例如，用户信息(B)5832是与该家庭的小孩相关的信息，包含作为小孩的喜好而喜欢体育的情况、作为面向小孩的可寻址CM而与棒球相关的CM合适的情况等信息。
用户识别部5630当在接收机5000a中作出规定的录像节目的播放操作或播放指示时，参照用户信息(A)5831、用户信息(B)5832……等，确定进行了该播放操作或播放指示的用户。
另外，在此的CM替换部5920在CM替换时，对于一个广播CM而替换为面向多个用户的多个可寻址CM。
(接收机的功能例)
图12是说明实施方式2的接收机5000a的功能例的图。在图12的例子中，接收机5000a的CM获取部5910例如预先获取与各用户的喜好相符的多个可寻址CMa、b、c。
如图12所示，CM替换部5920对于录像对象的广播节目中的面向大众CMx的一个广播段，使多个可寻址CMa、b、c由录像处理部5740录像。
由此，生成录像节目组5813s，该录像节目组5813s是包含多个可寻址CMa、b、c在内的可寻址CM组gp与广播节目一起被录像的录像节目组。录像处理部5740将该录像节目组5813s保存于录像节目存储部5810。
当在接收机5000a中作出录像节目组5813s的播放操作或播放指示时，用户识别部5630确定进行了播放操作或播放指示的用户。
播放处理部5750在播放录像节目组5813s时，从录像节目组5813s所包含的可寻址CM组gp之中选择面向由用户识别部5630确定的用户的任一可寻址CMa、b、c并且进行播放。
(接收机中的录像播放处理)
图13是表示实施方式2的接收机5000a中的录像播放处理的顺序的一例的流程图。
如图13所示，CM获取部5910从CM发布用服务器4000获取与各个收看者的喜好相符的可寻址CMa、b、c，并保存于CM存储部5820(步骤S301)。
录像处理部5740生成包含多个可寻址CMa、b、c在内的可寻址CM组gp与广播节目一起被录像的录像节目组5813s，并保存于录像节目存储部5810(步骤S302)。
当在操作接收部5610中接收到播放操作或播放指示时(步骤S303)，播放处理部5750判定该播放操作或播放指示是否以录像节目组5813s为对象(步骤S304)。如果不是以录像节目组5813s为对象(步骤S304：否)，则进入步骤S307。
如果以录像节目组5813s为对象(步骤S304：是)，则用户识别部5630参照用户信息(A)5831、用户信息(B)5832……等，确定进行了该播放操作或播放指示的用户(步骤S305)。
播放处理部5750从录像节目组5813s的可寻址CM组gp之中选择面向确定后的用户的可寻址CM(步骤S306)。
播放处理部5750开始播放录像节目(步骤S307)。
播放处理部5750在播放对象为录像节目组5813s的情况下，播放在步骤 S305中选择的可寻址CM(步骤S308)。
播放处理部5750结束录像节目的播放(步骤S309)。
通过以上所述，实施方式2的接收机5000a中的录像播放处理结束。
在实施方式2的系统中，即使在接收机5000a的收看者存在多人的情况下，也能够选择与各个收看者的喜好相符的可寻址CM而进行播放。
需要说明的是，在实施方式2的系统中，也可以适用实施方式1的变形例的结构。即，无论录像节目组的录像顺序是否为广播顺序，在录像节目的播放时都以正规的顺序播放。由此，即使应包含于录像节目的可寻址CM组的多个可寻址CM中的一个以上在播放开始时还未获取到，也能够生成录像节目组。
如以上所述，在上述的实施方式1、2及其变形例的系统中，例如，能够显示与收看用户的喜好相符的CM。
在实施方式1、2及其变形例的系统中，不仅能够从预先从CM发布用服务器4000下载且保存到CM存储部5820的可寻址CM之中选择可寻址CM，而且能够选择与用户的喜好更相符的可寻址CM。
由此，用户能够收看与自身的喜好更相符的CM。而且，作为提供CM的广告主MC及广告公司AD等的一方，能够向更想请其收看的对象有效地发布CM。而且，作为广播电台1000的一方，可寻址CM段的价值上升而带来收入增加。
在实施方式1、2及其变形例的系统中，在录像时进行CM的替换，由此不需要播放时的CM替换控制，能够简化播放控制。播放控制的简化导致作为播放装置的接收机5000的低价格化，也有助于接收机5000的普及率的提高。
由此，用户容易得到接收机5000的低价格化产生的经济性的优点。而且，作为提供CM的一方或广播电台1000的一方，通过普及具备上述那样的功能的接收机5000，能够得到可寻址CM的收看数量进一步增加这样的优点。
通过适用实施方式1、2及其变形例的系统的技术，例如即便在使用了不具有录像功能的播放装置的情况下，通过可移动媒介的使用及遥控收看等，也能够进行CM替换。
由此，用户得到更多的播放环境，能够收看与自身的喜好相符的CM。作为提供CM的一方或广播电台1000的一方，通过播放环境的充实，能够得到可寻址CM的收看数量进一步增加这样的优点。需要说明的是，在使用了可移动媒介的播放时，难以获取播放历史，但是根据录像实绩能够类推出实际收看数量。
[其他的实施方式]
在上述的实施方式1、2及其变形例中，对于一个管理服务器3000仅示出了一个接收机5000，但是并不局限于此。一个管理服务器可管理多个接收机。
在上述的实施方式1、2及其变形例中，在正篇与可寻址CM的编码不同的情况下，可以将一方的流按照另一方的流的编码进行再编码，或者将双方按照另外的编码进行再编码。由此，能够简化播放处理。
在上述的实施方式1、2及其变形例中，播放下载到接收机5000的录像节目存储部5810的可寻址CM，但是也可以基于MPEG-DASH(MPEG Dynamic Adaptive Streaming over HTTP)，对CM发布用服务器4000上的可寻址CM进行流播放。
在上述的实施方式1、2及其变形例中，说明了将广播节目内的CM段替换为可寻址CM的例子，但也可以对于通过互联网发布的内容适用实施方式1、2及其变形例。
另外，上述实施方式所示的各构成要素可以通过在计算机的硬盘装置等存储器中安装的程序来实现，而且可以将上述程序预先存储于计算机可读取的电子介质，通过使计算机从电子介质中读取程序而通过计算机来实现本发明的功能。作为电子介质，例如包含CD-ROM等记录介质或闪存器、可移动媒介等。此外，可以在经由网络连接的不同的计算机中分散存储构成要素，通过在使各构成要素发挥功能的计算机间进行通信来实现。
虽然说明了本发明的实施方式，但是该实施方式是作为例子而提示的方式，没有限定发明的范围。该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。
