接着，说明第一实施方式的画质调整***1的各装置的功能。图7是示出第一实施方式的画质调整***1的各装置的功能结构的一个例子的框图。
管理服务器10的CPU101通过将ROM103等中存储的程序读出并执行，从而在RAM102中生成各功能部。具体而言，管理服务器10具备存储控制部1001、更新部1002、以及发送部1003作为功能部。
存储控制部1001使存储部104存储表示内容的画质的特性的内容特性信息107、以及表示每个内容的画质的特性的显示设定的显示设定信息109。进一步，存储控制部1001使存储部104存储表示内容的画质的特性各自的特征的特性内容信息106。
更新部1002更新特性内容信息106、内容特性信息107、以及显示设定信息109。另外，更新部1002既可以将特性内容信息106、内容特性信息107、以及显示设定信息109全部在同时期更新，也可以在不同的时期更新。即，更新部1002将特性内容信息106、内容特性信息107、以及显示设定信息109中的至少任一个更新。在此，更新部1002进行的各种信息的更新方法没有限定。例如，更新部1002可以基于由画质调整***1的管理者进行的操作来更新各种信息，也可以利用通过深度学习而生成的学习后模型来更新各种信息，还可以基于接收到的数据来更新各种信息。
发送部1003将特性内容信息106、内容特性信息107、以及显示设定信息109发送到电视装置20。更详细而言，在存储部104中存储的特性内容信息106、内容特性信息107、以及显示设定信息109比请求源的电视装置20具有的特性内容信息106、内容特性信息107、以及显示设定信息109新的情 况下，发送部1003向电视装置20发送。另外，发送部1003在发送显示设定信息109的情况下，发送与请求源的电视装置20的设备种类相符的显示设定信息109。
进一步，在未由更新部1002将特性内容信息106、内容特性信息107、以及显示设定信息109全部更新的情况下，发送部1003也可以不发送未更新的信息。即，发送部1003发送特性内容信息106、内容特性信息107、以及显示设定信息109中的至少任一个。
电视装置20的CPU214通过将ROM等中存储的程序读出并执行从而在RAM中生成各功能部。具体而言，电视装置20具备内容获取部2001、接收部2002、设定变更部2003、特性确定部2004、及显示控制部2005作为功能部。
内容获取部2001通过接收广播，从而获取具有元数据、视像信号及声音信号的内容。
接收部2002接收用于确定内容的画质的特性的内容特性信息107、以及表示每个特性的内容的显示设定的显示设定信息109。另外，接收部2002接收特性内容信息106。接收部2002是第一接收部的一个例子。
更详细而言，接收部2002在每经过任意的期间时，判定管理服务器10的存储部104中存储的特性内容信息106、内容特性信息107、以及显示设定信息109是否比电视装置20具有的特性内容信息106、内容特性信息107、以及显示设定信息109新。即，接收部2002在前次接收了特性内容信息106、内容特性信息107、以及显示设定信息109之后，判定特性内容信息106、内容特性信息107、以及显示设定信息109是否已被更新。然后，接收部2002在管理服务器10的存储部104中存储的特性内容信息106、内容特性信息107、以及显示设定信息109比电视装置20具有的特性内容信息106、内容特性信息107、以及显示设定信息109新的情况下，向管理服务器10请求特性内容信息106、内容特性信息107、以及显示设定信息109。由此，接收部2002接收特性内容信息106、内容特性信息107、以及显示设定信息109。
设定变更部2003将按照每个内容的画质的特性而设置的显示设定中的、在电视装置20中未变更设定的项目变更成显示设定信息109所示的设定。设定变更部2003是变更部的一个例子。在此，用户基于自己的喜好来变更电视装置20的显示设定。电视装置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。因此，设定变更部2003对用户未变更的显示设定的项目进行变更。此外，设定变更部2003也可以基于用户变更了的设定来变更显示设定的各项目。例如，在显示设定信息109表示着对于某个项目进行了+3的设定变更的情况下，设定变更部2003也可以执行对用户设定了的设定值加上3的设定变更。
特性确定部2004基于内容特性信息107来确定广播的内容的画质的特性。特性确定部2004是第一确定部的一个例子。在此，在内容中包含表示内容(contents)的信息的元数据。在元数据中包含广播方法、SID、种类(Genre)、Code等信息、内容的标题、对内容的概要进行说明的注释等。特性确定部2004将内容特性信息107与内容的元数据进行比较，来判定是否与任一行(row)相符。然后，特性确定部2004判定由相符的行(row)的画质特性码确定的特性为内容的画质的特性。
在此，在追加了新节目、广播方法的情况下，内容特性信息107中追加新的行(row)。因此，特性确定部2004按照行(row)为新的顺序来判定是否与行(row)相符。由此，特性确定部2004能够选择适当的特性。
显示控制部2005使基于由特性确定部2004确定了的特性的显示设定进行了调整后的内容显示在显示面板210上。更详细而言，显示控制部2005基于由特性确定部2004确定了的特性的显示设定来调整内容。然后，显示控制部2005使调整后的内容显示在显示面板210上。由此，显示控制部2005能够利用与内容的画质的特性相符的显示设定来显示。
接着，说明第一实施方式的画质调整***1的各装置执行的处理。
图8是示出第一实施方式的管理服务器10执行的信息管理处理的一个例子的流程图。
更新部1002判定是否接收了请求特性内容信息106、内容特性信息107、以及显示设定信息109的至少任一个的更新的更新请求(步骤S1)。
在接收了更新请求的情况下(步骤S1；是)，更新部1002更新成为更新请求的对象的信息(步骤S2)。
在未接收到更新请求的情况下(步骤S1；否)，发送部1003判定是否从电视装置20接收了请求特性内容信息106、内容特性信息107、以及显示设定信息109的至少任一个的发送的发送请求(步骤S3)。在未接收到发送请求的情况下(步骤S3；否)，管理服务器10转移到步骤S1。
在接收了发送请求的情况下(步骤S3；是)，发送部1003将成为发送请求的对象的信息发送到电视装置20(步骤S4)。
如上所述，管理服务器10执行信息管理处理。
图9是示出第一实施方式的电视装置20执行的调整处理的一个例子的流程图。
在电视装置20接收后，接收部2002判定更新了的特性内容信息106、内容特性信息107、或显示设定信息109是否已被存储在管理服务器10中(步骤S11)。
在更新了的特性内容信息106、内容特性信息107、或显示设定信息109已被存储在管理服务器10中的情况下(步骤S11；是)，接收部2002从管理服务器10接收更新了的特性内容信息106、内容特性信息107、或显示设定信息109(步骤S12)。
在更新了的特性内容信息106、内容特性信息107、或显示设定信息109未被存储在管理服务器10中的情况下(步骤S11；否)，内容获取部2001判定是否获取了内容(步骤S13)。在未获取到内容的情况下(步骤S13；否)，电视装置20转移到步骤S11。
在获取了内容的情况下(步骤S13；是)，特性确定部2004基于内容特性信息107来确定内容的画质的特性(步骤S14)。
显示控制部2005基于由特性确定部2004确定了的特性的显示设定来调 整视像信号(步骤S15)。显示控制部2005使调整了的视像信号显示在显示面板210上(步骤S16)。
如上所述，电视装置20执行调整处理。
如上所述，第一实施方式的电视装置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，电视装置20对于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。另外，电视装置20在获取到广播的内容的情况下，基于内容特性信息107来确定内容的画质的特性。然后，电视装置20使显示面板210显示基于显示设定信息109确定了的特性的显示设定进行了调整后的内容。因此，电视装置20能够不会变更用户的设定地利用与内容的特性相应的设定来显示内容。
第二实施方式
第二实施方式的画质调整***1a具备电视***40，该电视***40连接有电视装置20a和录像机50。此外，对于与第一实施方式相同的结构赋予相同的附图标记并省略说明。
图10是示出第二实施方式的画质调整***1a的结构的一个例子的图。画质调整***1a具备电视***40。电视***40是使从录像机50提供的内容以能够收看的方式显示在电视装置20a上的***。
录像机50是将广播的内容存储到HDD等存储介质中的信息记录播放装置。而且，录像机50将存储了的内容输出到电视装置20a。由此，电视装置20a使录像机50存储的内容以能够收看的方式显示。
管理服务器10a经由网络30与电视***40具有的电视装置20a及录像机50分别连接。在此，视像调整数据包108具备电视装置20a的每个设备种类的显示设定信息109。即，显示设定信息109是指定电视装置20a的每个设备种类的显示设定的信息。因此，管理服务器10a将显示设定信息109发送到电视装置20a，但是不发送到录像机50。而且，基于由电视装置20a的显示设定信息109设定的显示设定来显示从录像机50输出的内容。
电视装置20a与录像机50由HDMI(注册商标)(High－Definition  Multimedia Interface：高清多媒体接口)等线缆41连接。此外，线缆41不限于HDMI(注册商标)，也可以根据其它的规范来连接。
接着，说明录像机50的硬件结构。图11是示出第二实施方式的录像机50的硬件结构的一个例子的框图。录像机50具备调谐器501、控制部502、连接接口503、存储部504、以及光盘读写器505。
调谐器501从广播信号中选择期望的频道的广播信号。另外，调谐器501通过对选台的广播信号进行解调，从而生成元数据、视像信号及声音信号。
控制部502是控制录像机50整体的SoC(System on a Chip：片上***)。控制部502具备CPU、RAM、及ROM。CPU通过执行各种计算机程序，从而控制录像机50的各组件。在CPU执行程序时，RAM临时存储各种程序、各种数据。ROM是存储程序、数据的存储介质。而且，CPU将RAM作为工作分区(作业区域)来执行ROM等中存储的程序。
例如，控制部502使具有调谐器501生成的元数据、视像信号及声音信号的内容存储到存储部504中，或者使光盘读写器505写入到光盘中。另外，控制部502使连接接口503发送存储部504中存储的内容、光盘读写器505从光盘中读取到的内容。
连接接口503是用于经由线缆41来执行与电视装置20a的通信的接口。
存储部504是HDD、SSD等存储装置。存储部504存储具有调谐器501生成了的元数据、视像信号及声音信号的内容。
光盘读写器505对于DVD(Digital Versatile Disc：数字通用光盘)、蓝光光盘等光盘执行信息的读出、写入。
接着，说明第二实施方式的画质调整***1a的各装置的功能。图12是示出第二实施方式的画质调整***1a的各装置的功能结构的一个例子的框图。
管理服务器10a的CPU101通过读出并执行ROM103等中存储的程序，从而在RAM102中生成各功能部。具体而言，管理服务器10a具备存储控制部1001、更新部1002、及发送部1003a作为功能部。
存储控制部1001及更新部1002具有与第一实施方式同样的功能。
发送部1003a对电视装置20a发送特性内容信息106、内容特性信息107、以及显示设定信息109。另一方面，发送部1003a对录像机50发送特性内容信息106及内容特性信息107。即，发送部1003a对录像机50不发送显示设定信息109。
录像机50的控制部502具有的CPU通过读出并执行ROM等中存储的程序，从而在RAM中生成各功能部。此外，控制部502也可以利用集成电路来实现各功能部的全部或一部分。而且，录像机50具备内容获取部5001、内容记录部5002、接收部5003、特性确定部5004、以及连接控制部5005作为功能部。
内容获取部5001通过接收广播，从而获取具有元数据、视像信号及声音信号的内容。
内容记录部5002使内容获取部5001获取到的内容存储在存储部504、光盘等存储介质中。
接收部5003从管理服务器10a接收特性内容信息106及用于确定内容的画质的特性的内容特性信息107。接收部5003是第二接收部的一个例子。
特性确定部5004基于内容特性信息107来确定内容的画质的特性。特性确定部5004是第二确定部的一个例子。更详细而言，特性确定部5004比较内容特性信息107与内容的元数据，来判定是否与任一行(row)相符。而且，特性确定部5004判定为由相符的行(row)的画质特性码来确定的特性是内容的画质的特性。另外，特性确定部5004按照行(row)为新的顺序来判定是否与行(row)相符。由此，特性确定部5004能够选择适当的特性。
连接控制部5005控制与电视装置20a的连接。例如，连接控制部5005利用CEC(Consumer Electronics Control：消费电子控制)来从电视装置20a接收对应设备种类信息和功能状态信息。对应设备种类信息是表示是否是具有使基于从管理服务器10a获取到的显示设定信息109进行了调整后的内容进行显示的功能的设备种类的信息。功能状态信息是表示使基于从管理服务器10a获取到的显示设定信息109进行了调整后的内容进行显示的功能是否 为有效的信息。
另外，连接控制部5005输出由特性确定部5004确定了的画质特性码及内容。连接控制部5005是输出部的一个例子。更详细而言，连接控制部5005从存储部504、光盘读写器505读出内容。在特性确定部5004对于读出了的内容确定了画质特性码的情况下，连接控制部5005将画质特性码及内容输出到电视装置20a。
另外，连接控制部5005也可以将源信息发送到电视装置20a。源信息是表示获取了向电视装置20a输出的内容的获取源的信息。例如，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，根据获取源的不同，构成内容的数据不同。因此，连接控制部5005通过发送源信息，从而能够使其用于内容的画质的特性的确定。
电视装置20a的CPU214通过读出并执行ROM等中存储的程序，从而在RAM中生成各功能部。具体而言，电视装置20a具备内容获取部2001、接收部2002、设定变更部2003、特性确定部2004、连接控制部2007、及显示控制部2005a作为功能部。
内容获取部2001、接收部2002、设定变更部2003、及特性确定部2004具有与第一实施方式同样的功能。
即，接收部2002从管理服务器10a接收显示设定信息109。然后，设定变更部2003将按照每个内容的画质的特性而设置的显示设定中的、未在电视装置20a中变更过设定的项目变更成显示设定信息109所示的设定。
连接控制部2007控制与录像机50的连接。连接控制部2007利用CEC将本装置的对应设备种类信息和功能状态信息发送到录像机50。另外，连接控制部2007从录像机50接收画质特性码和内容的输入。连接控制部2007是输入部的一个例子。进一步，连接控制部2007也可以从录像机50接收源信息的输入。
显示控制部2005a使显示面板210显示基于由连接控制部2007接收到的画质特性码确定的特性的显示设定进行了调整后的内容。更详细而言，显示 控制部2005基于由连接控制部2007接收到的画质特性码确定的特性的显示设定来调整内容。然后，显示控制部2005使调整后的内容显示在显示面板210上。由此，显示控制部2005利用与内容的画质的特性相符的显示设定来进行显示。
进一步，显示控制部2005a在连接控制部2007接收到源信息的情况下，基于由画质特性码及源信息确定的特性的显示设定来调整内容。然后，显示控制部2005使调整后的内容显示在显示面板210上。由此，显示控制部2005a能够按照与内容的获取源相符的设定来显示内容。
接着，说明第二实施方式的画质调整***1a的各装置执行的处理。图13是示出第二实施方式的电视***40执行的显示处理的一个例子的流程图。
录像机50的接收部5003执行接收内容特性信息107及显示设定信息109的接收处理(步骤S21)。即，在管理服务器10a的存储部104中存储的内容特性信息107及显示设定信息109比录像机50存储的内容特性信息107及显示设定信息109新的情况下，接收部5003接收内容特性信息107及显示设定信息109。
电视装置20a的接收部2002执行接收特性内容信息106、内容特性信息107、以及显示设定信息109的接收处理(步骤S22)。即，在管理服务器10a的存储部104中存储的特性内容信息106、内容特性信息107、以及显示设定信息109比电视装置20a存储的特性内容信息106、内容特性信息107、以及显示设定信息109新的情况下，接收部2002接收特性内容信息106、内容特性信息107、以及显示设定信息109。
