具体实施方式
以下，参照附图，详细说明实施方式。
第一实施方式
图1是示出第一实施方式的画质调整系统1的构成的一个例子的图。画质调整系统1具备管理服务器10及电视设备20。管理服务器10与电视设备20经由网络30可通信地连接。另外，图1所示的画质调整系统1具备管理服务器10及电视设备20各一台。但是，画质调整系统1不限于具备一台这些设备，也可以具备多台。
管理服务器10是个人计算机、云计算等服务器设备。另外，管理服务器10不限于一台服务器设备，也可以由多台服务器设备构成。管理服务器10存储有：表示内容的画质的特性各自的特征的特征内容信息106(参照图2)；用于确定内容的画质的特性的内容特性信息107(参照图2)；表示与内容的画质的特性匹配的显示设定的显示设定信息109(参照图2)；以及表示内容的各场景的内容的内容场景信息110(参照图2)。而且，管理服务器10将特征内容信息106、内容特性信息107、显示设定信息109及内容场景信息110发送到经由网络30连接的电视设备20。
此外，在本实施方式中，以管理服务器10存储有特征内容信息106、内容特性信息107、显示设定信息109及内容场景信息110的情况为例进行说明，但是，特征内容信息106、内容特性信息107、显示设定信息109及内容场景信息110也可以存储在各自不同的服务器设备中。
电视设备20是使广播的内容以可收看方式显示的广播接收设备。电视设备20在接收到显示设定信息109的情况下，将显示设定中的、未由用户变更设定的项目变更成显示设定信息109所示的设定。由此，电视设备20以与广播的内容中包含的内容匹配的显示设 定来显示内容。
在此，在内容中不仅包含内容的主体部分，还包含商业部分。所谓商业部分，是与内容不同的图像。即，商业部分不限于广告的图像，也可以是其它图像。因为主体部分与商业部分是不同的图像，所以电视设备20若以与主体部分的画质匹配的显示设定来显示商业部分，则会导致以不适当的显示设定来显示商业部分。在此，电视设备20对于商业部分，不应用从管理服务器10获取到的内容的显示设定。而且，电视设备20以在电视设备20中设定的显示设定来显示商业部分。此外，在不应用与从管理服务器10获取到的主体部分的画质匹配的显示设定的情况下，电视设备20也可以将商业部分以任意的显示设定来显示。由此，电视设备20能够防止以不适当的设定来显示商业部分的情况。
接下来，说明画质调整系统1的各设备的硬件结构。图2是示出第一实施方式的管理服务器10的硬件结构的一个例子的框图。

另外，在特征内容信息106、内容特性信息107、显示设定信息109全部未由更新部1002更新的情况下，通信部1003也可以不发送未更新的信息。
另外，通信部1003在从电视设备20接收了内容信息的情况下，将根据接收到的内容信息确定的场景信息向发送了内容信息的电视设备20发送。更详细而言，通信部1003在从电视设备20接收了用于确定内容的内容信息的情况下，从内容场景信息110提取与内容信息建立关联的场景信息。然后，通信部1003向发送了内容信息的电视设备20发送提取出的场景信息。即，通信部1003发送包含检测标志在内的特征内容信息106、内容特性 信息107、显示设定信息109以及内容场景信息110中的至少任一个。通信部1003是发送部的一个例子。
电视设备20的CPU214通过读取在ROM等中存储的程序并执行，从而在RAM中生成各功能部。具体而言，电视设备20中作为功能部具备内容获取部2001、接收部2002、操作控制部2003、内容管理部2004、场景管理部2005、受理部2006、画质变更部2007、以及显示控制部2008。
内容获取部2001通过接收广播，来获取具有元数据、图像信号及声音信号的内容。然后，内容获取部2001使存储器216等存储获取到的元数据及内容。
接收部2002接收内容特性信息107和显示设定信息109，该内容特性信息107具有检测标志，该检测标志设定有是否按照内容中包含的主体部分的画质的每个特性来区别主体部分和商业部分，该显示设定信息109表示内容中包含的主体部分的画质的每个特性的显示设定。接收部2002是第一接收部的一个例子。另外，接收部2002接收特征内容信息106。
更详细而言，每当经过任意的期间，接收部2002判定管理服务器10的存储部104中存储的特征内容信息106、内容特性信息107及显示设定信息109是否比电视设备20具有的特征内容信息106、内容特性信息107及显示设定信息109新。即，接收部2002判定在前次接收到特征内容信息106、内容特性信息107及显示设定信息109之后是否更新了特征内容信息106、内容特性信息107及显示设定信息109。然后，在管理服务器10的存储部104中存储的特征内容信息106、内容特性信息107及显示设定信息109比电视设备20具有的特征内容信息106、内容特性信息107及显示设定信息109新的情况下，接收部2002向管理服务器10请求特征内容信息106、内容特性信息107及显示设定信息109。由此，接收部2002接收特征内容信息106、内容特性信息107及显示设定信息109。
操作控制部2003通过控制操作部211从而接收各种操作。例如，操作控制部2003接收使指定的内容播放的操作。另外，操作控制部2003接收在播放中的内容中变更播放位置的操作。即，操作控制部2003接收在播放中的内容中变更要播放的场景的操作。
内容管理部2004管理内容。更详细而言，在内容存储于存储部104等的情况下，内容管理部2004执行内容的分节(chapter)。即，内容管理部2004确定将内容按每个场景进行划分的位置。例如，内容管理部2004确定对内容中包含的主体部分与商业部分进行划分的播放位置。另外，内容管理部2004生成表示对内容中包含的各个场景进行划分的位置的节(chapter)信息。而且，内容管理部2004将节信息通知给场景管理部2005。另外，内容管理部2004向管理服务器10发送表示要播放的内容的内容信息。
场景管理部2005管理播放中的内容的场景。更详细而言，作为由内容管理部2004发送的内容信息的响应，场景管理部2005接收根据内容信息确定的内容的场景信息。另外，场景管理部2005从内容管理部2004获取节信息。然后，场景管理部2005基于场景信息和节信息来判定播放中的内容的场景是否被变更。
另外，场景管理部2005根据内容而检测商业部分。场景管理部2005是检测部的一个例子。更详细而言，场景管理部2005基于场景信息和节信息，从内容中检测商业部分。场景管理部2005通过对节信息与变更后的播放位置进行比较，从而确定变更后的播放位置所属的场景。然后，场景管理部2005通过对场景信息与变更后的播放位置所属的场景进行比较，来判定变更后的播放位置所属的场景是主体部分、还是商业部分。由此，场景 管理部2005根据内容而检测商业部分。然后，场景管理部2005向受理部2006通知变更后的场景是商业部分、还是主体部分。此外，上述的检测商业部分的方法是一个例子，场景管理部2005可以利用任意的方法来检测商业部分。
在由场景管理部2005判定为播放中的内容的场景被变更了的情况下，受理部2006判定是否为显示设定信息109的显示设定的应用对象。
更详细而言，受理部2006基于内容特性信息107，确定画质特性码，该画质特性码表示播放中的内容的主体部分的画质的特性。在此，内容中包含表示内容(content)的信息的元数据。在元数据中包含广播方法、SID、种类、代码等信息、内容的标题、说明内容的概要的解释语句等。受理部2006对内容特性信息107与播放中的内容的元数据进行比较，判定与哪个行(row)相匹配。然后，受理部2006将匹配的行的画质特性码判定为播放中的内容的画质特性码。在此，在追加了新的节目、广播方法的情况下，对内容特性信息107追加新的行。在此，受理部2006按照行新的顺序来判定是否与行匹配。由此，受理部2006能够选择适当的画质特性码。即，受理部2006确定与内容的主体部分匹配的画质的特性。
受理部2006基于内容特性信息107的检测标志和播放对象的内容中包含的主体部分的画质的特性，来判定是否对主体部分与商业部分进行区别。换言之，受理部2006基于内容特性信息107的检测标志和播放对象的内容中包含的主体部分的画质的特性，来判定是否从内容中检测商业部分。受理部2006是第一判定部的一个例子。在检测标志为“0”的情况下，即，在商业部分的检测对象外的情况下，受理部2006判定为显示设定信息109的显示设定的应用对象。
另一方面，在检测标志为“1”的情况下，即，在商业部分的检测对象的情况下，受理部2006以变更后的场景为商业部分的状况作为条件，判定为显示设定信息109的显示设定的应用对象外。即，在检测标志为“1”的情况下，受理部2006以变更后的场景为主体部分的状况作为条件，判定为显示设定信息109的显示设定的应用对象。
受理部2006在判定为应用对象的情况下，将表示播放中的内容的主体部分的画质的特性的画质特性码通知给画质变更部2007。另外，受理部2006在判定为应用对象外的情况下，向画质变更部2007通知为应用对象外的状况。
在被判定为对主体部分与商业部分进行区别的情况下，画质变更部2007根据内容的场景来变更显示设定信息109对主体部分的显示设定与商业部分的显示设定。换言之，在由受理部2006判定为从内容中检测商业部分的情况下，画质变更部2007根据内容的场景来变更显示设定信息109对主体部分的显示设定与商业部分的显示设定。画质变更部2007是变更部的一个例子。在由受理部2006通过检测商业部分从而判定为进行区别的情况下，画质变更部2007通过将场景管理部2005检测到的商业部分设置为显示设定信息109的显示设定的应用对象外，从而变更成商业部分的显示设定。即，画质变更部2007对于商业部分不应用显示设定信息109的显示设定。
在由受理部2006判定为不检测商业部分从而向画质变更部2007通知了画质特性码的情况下，画质变更部2007基于显示设定信息109来变更成由画质特性码确定的显示设定。或者，在虽然由受理部2006判定为检测商业部分，但是由于变更后的画面为主体部分而向画质变更部2007通知了画质特性码的情况下，画质变更部2007基于显示设定信息109来变更成由画质特性码确定的显示设定。
另外，在由受理部2006判定为检测商业部分，并因为变更后的场景是商业部分而判定为应用对象外的情况下，画质变更部2007不应用显示设定信息109的显示设定。换言之，画质变更部2007对于商业部分不应用基于显示设定信息109的显示设定。在不应用基于显示设定信息109的显示设定的情况下，画质变更部2007采用什么样的显示设定是任意的。例如，画质变更部2007既可以应用在电视设备20中已设定的显示设定，也可以应用事先准备好的显示设定。
在此，用户基于自己的喜好来变更电视设备20的显示设定。电视设备20在显示内容的情况下，优选以与用户的喜好相应的显示设定来显示。在此，画质变更部2007也可以对用户未变更的显示设定的项目进行变更。
显示控制部2008基于由画质变更部2007设定的显示设定，使内容显示于显示面板210。显示控制部2008是显示控制部的一个例子。由此，显示控制部2008使内容中包含的商业部分和主体部分以与各自的画质的特性匹配的显示设定来显示。
接下来，说明第一实施方式的画质调整系统1的各设备执行的处理。图8是示出第一实施方式的画质调整系统1的各设备执行的显示处理的一个例子的序列图。

管理服务器10的通信部1003将根据发送的内容信息确定的内容的场景信息发送到电视设备20(步骤S4)。
电视设备20的场景管理部2005基于从内容管理部2004通知的节信息和从管理服务器10接收到的场景信息，来判定播放中的内容的场景是否进行了变更(步骤S5)。在场景未变更的情况下(步骤S5：否)，场景管理部2005等待。
在场景变更了的情况下(步骤S5：是)，场景管理部2005通知变更后的场景是商业部分、还是主体部分(步骤S6)。
受理部2006判定是否为基于显示设定信息109的显示设定的应用对象(步骤S7)。更详细而言，受理部2006基于内容特性信息107，确定画质特性码，该画质特性码表示播放中的内容的画质的特性。另外，受理部2006基于与确定出的画质特性码建立关联的检测标志，判定是否为检测商业部分的检测对象的内容。是检测对象外的内容的情况下，受理部2006判定为是应用对象。是检测对象的内容的情况下，受理部2006以变更后的场景为主体部分的状况作为条件，判定为是应用对象。是检测对象的内容的情况下，受理部2006以变更后的场景为商业部分的状况作为条件，判定为是应用对象外。
受理部2006向画质变更部2007通知是否为应用对象的判定结果(步骤S8)。是应用对象的情况下，受理部2006通知画质特性码。是应用对象外的情况下，受理部2006通知是应用对象外的情况。
画质变更部2007基于从受理部2006通知的判定结果来变更显示设定(步骤S9)。画质变更部2007在被通知了画质特性码的情况下，变更成由画质特性码确定的显示设定。画质变更部2007在被通知了是应用对象外的情况下，不应用基于显示设定信息109的显示设定。
如上所述，画质调整系统1的各设备执行显示处理。
如上所述，第一实施方式的电视设备20从管理服务器10接收内容特性信息107和显 示设定信息109。另外，电视设备20基于内容特性信息107的检测标志和播放对象的内容的画质的特性，判定是否对主体部分与商业部分进行区别。电视设备20以是区别对象的状况作为条件，在变更后的场景为主体部分的情况下与为商业部分的情况下变更显示设定。然后，电视设备20基于显示设定，使内容显示于显示面板210。因此，电视设备20能够防止以不适当的设定来显示商业部分的情况。
第二实施方式
第二实施方式的画质调整系统1a具备电视系统40，该电视系统40连接有电视设备20a和录像机(recorder)50。此外，对于与第一实施方式相同的构成，标注相同的附图标记并省略说明。

接收部5002具有与接收部2002同样的功能。即，接收部5002接收内容特性信息107，该内容特性信息107具有检测标志，该检测标志设定有是否按照内容中包含的主体部分的画质的每个特性来区分主体部分与商业部分。接收部5002是第二接收部的一个例子。
操作控制部5003具有与操作控制部2003同样的功能。
内容管理部5004具有与内容管理部2004同样的功能。内容管理部5004基于具有检测标志的内容特性信息107和播放对象的内容中包含的主体部分的画质的特性，来判定是否要对内容的主体部分与商业部分进行区别。内容管理部5004是第二判定部的一个例子。
场景管理部5005具有与场景管理部2005同样的功能。
受理部5006具有与受理部2006同样的功能。
连接控制部5007控制经由线缆41的与电视设备20a的连接。例如，连接控制部5007控制HDMI(注册商标)CEC(Consumer Electronics Control：消费电子控制)的连接。例如，连接控制部5007从电视设备20a接收对应机种信息和功能状态信息。对应机种信息是表示是否为具有基于从管理服务器10a获取到的显示设定信息109使内容显示的功能的机种的信息。功能状态信息是表示基于从管理服务器10a获取到的显示设定信息109使内容显示的功能是否成为有效的信息。
另外，连接控制部5007输出受理部5006的判定结果。连接控制部5007是输出部的一个例子。更详细而言，连接控制部5007输出是否为基于显示设定信息109的显示设定的应用对象的判定结果。即，在由受理部5006判定为是应用对象的情况下，连接控制部5007输出具有画质特性码的判定结果，该画质特性码表示播放中的内容的主体部分的画质的特性。另外，在由受理部5006判定为是应用对象外的情况下，连接控制部5007输出表示为应用对象外的判定结果。此外，表示为应用对象外的判定结果也可以是表示为应用对象外的画质特性码。
另外，连接控制部5007输出内容。更详细而言，连接控制部5007从存储部504、光盘读写器505读出内容。然后，在受理部5006对于读出的内容确定了画质特性码的情况下，连接控制部5007将画质特性码及内容输出到电视设备20a。
另外，连接控制部5007也可以将来源(source)信息发送到电视设备20a。来源信息是表示获取了向电视设备20a输出的内容的获取源的信息。例如，来源信息是表示蓝光光盘、DVD、地面波数字广播等获取源的信息。在此，有的情况下，构成内容的数据根据获取源而不同。因此，连接控制部5007通过发送来源信息而能够在内容的画质的特性的确定中使用。
电视设备20a的CPU214通过读取在ROM等中存储的程序并执行，从而在RAM中生成各功能部。具体而言，电视设备20a中作为功能部具备内容获取部2001、接收部2002、操作控制部2003、内容管理部2004、场景管理部2005、连接控制部2009、受理部2006a、画质变更部2007及显示控制部2008。
内容获取部2001、接收部2002、操作控制部2003、内容管理部2004、场景管理部2005、画质变更部2007及显示控制部2008具有与第一实施方式同样的功能。
连接控制部2009控制与录像机50的连接。更详细而言，连接控制部2009接收由受理部5006判定的判定结果的输入。连接控制部2009是输入部的一个例子。连接控制部2009从录像机50接收具有画质特性码的判定结果、及内容的输入，该画质特性码表示播放中的内容的主体部分的画质的特性。另外，连接控制部2009也可以从录像机50接收来源信息的输入。另外，连接控制部2009利用CEC将本设备的对应机种信息和功能状态信息发送到录像机50。
受理部2006a具有与第一实施方式的受理部2006同样的功能。另外，受理部2006a在与录像机50连接的情况下，将连接控制部2009接收到的判定结果通知给画质变更部2007。即，受理部2006a将具有画质特性码的判定结果通知给画质变更部2007，该画质特性码表示播放中的内容的主体部分的画质的特性。
与第一实施方式同样，在由受理部2006a判定为根据内容而检测商业部分的情况下，画质变更部2007根据内容的场景来变更显示设定信息109对主体部分的显示设定与商业部分的显示设定。即，在根据连接控制部2009接收到的判定结果判定为对主体部分与商业部分进行区别的情况下，画质变更部2007根据内容的场景来变更显示设定信息109对主体部分的显示设定与商业部分的显示设定。
与第一实施方式同样，显示控制部2008基于由画质变更部2007设定的显示设定，使内容显示于显示面板210。由此，显示控制部2008使内容中包含的商业部分和主体部分以与各自的画质的特性匹配的显示设定进行显示。
接下来，说明第二实施方式的画质调整系统1a的各设备执行的处理。图12是示出第二实施方式的画质调整系统1a执行的显示处理的一个例子的序列图。
录像机50的操作控制部5003接收使内容播放的操作(步骤S21)。
内容管理部5004将表示要播放的内容的内容信息发送到管理服务器10a(步骤S22)。另外，内容管理部5004将要播放的内容的节信息通知给场景管理部5005(步骤S23)。
管理服务器10a的通信部1003a将根据被发送的内容信息确定的内容的场景信息发送到录像机50(步骤S24)。
录像机50的场景管理部5005基于从内容管理部5004通知的节信息和从管理服务器10a接收到的场景信息，判定是否变更了播放中的内容的场景(步骤S25)。在场景未变更的情况下(步骤S25：否)，场景管理部5005等待。
场景变更了的情况下(步骤S25：是)，场景管理部5005通知变更后的场景是商业 部分、还是主体部分(步骤S26)。
受理部5006判定是否为基于显示设定信息109的显示设定的应用对象(步骤S27)。更详细而言，受理部5006基于内容特性信息107来确定画质特性码，该画质特性码表示播放中的内容的画质的特性。另外，受理部5006基于与确定出的画质特性码建立关联的检测标志，来判定是否为检测商业部分的检测对象的内容。在是检测对象外的内容的情况下，受理部5006判定为是应用对象。在是检测对象的内容的情况下，受理部5006以变更后的场景为主体部分的状况作为条件而判定为应用对象。在是检测对象的内容的情况下，受理部5006以变更后的场景为商业部分的状况作为条件而判定为应用对象外。
受理部5006使是否为基于显示设定信息109的显示设定的应用对象的判定结果输出到连接控制部5007(步骤S28)。即，在是应用对象的情况下，连接控制部5007将画质特性码输出到电视设备20a。另外，在是应用对象外的情况下，受理部2006将是应用对象外的状况通知给电视设备20a。
受理部2006a将连接控制部2009接收到的判定结果通知给画质变更部2007(步骤S29)。
画质变更部2007基于被通知的判定结果来变更显示设定(步骤S30)。画质变更部2007在作为判定结果被通知了画质特性码的情况下，变更成由画质特性码确定的显示设定。画质变更部2007在作为判定结果被通知了是应用对象外的状况的情况下，不应用显示设定信息109进行的显示设定。
如上所述，画质调整系统1a的各设备执行显示处理。
如以上所述，第二实施方式的录像机50从管理服务器10接收内容特性信息107和显示设定信息109。另外，录像机50基于内容特性信息107的检测标志和播放对象的内容的画质的特性来判定是否对主体部分与商业部分进行区别。然后，录像机50将判定结果输出到电视设备20a。电视设备20a接收判定结果的输入。电视设备20以是区别对象的状况作为条件，在变更后的场景为主体部分的情况下与变更后的场景为商业部分的情况下，变更显示设定。而且，电视设备20基于显示设定，使内容显示于显示面板210。因此，电视设备20能够防止以不适当的设定来显示商业部分的情况。
此外，本实施方式的各设备(管理服务器10、管理服务器10a、电视设备20、电视设备20a、录像机50)中执行的程序能够用可安装的形式或可执行的形式的文件记录在CD(Compact Disc：光盘)－ROM(Read Only Memory：只读存储器)、软盘(FD)、CD－R(Recordable：刻录盘)、DVD(Digital Versatile Disk：数字通用盘)等计算机设备可读取的记录介质中而提供。另外，也可以经由互联网等网络来提供或发布该程序。
说明了本申请的实施方式，但是，该实施方式是作为例子而示出的，并不意图限定申请的范围。该新的实施方式能够以其它的各种各样的形态来实施，在不脱离申请的主旨的范围能够进行各种省略、置换、变更。这些实施方式及其变形包含在申请的范围、主旨中，并且，包含在权利要求书记载的技术方案及其等同的范围中。
