图2是表示本发明实施例的数字广播接收便携终端的外观的俯视图,图2(a)表示盖部打开时的状态,图2(b)表示盖部关闭时的状态。
图3是表示盖关闭时副画面的显示实例的说明图。
具体实施方式
以下根据图1-图3对本发明的实施例进行说明。
图1是表示本实施例的便携式数字广播接收便携终端(带手机功能)的方框图,图2是表示数字广播接收便携终端2的外观的主视图。
本实施例的数字广播接收便携终端2如图2(a)(b)所示那样,构成为折叠式的带有手机功能的数字广播接收便携终端。即,具有盖部2b相对于主体2a按照可旋转的方式设置的折叠式形态,在上述盖部2b的内面侧具有主LCD屏202a,在外面侧具有副LCD屏202b。上述盖部2b的开闭可通过开闭检测开关231检测。
数字广播接收便携终端2如图1所示,根据通过地面波数字调谐器230的广播接收而获得的编码影像声音数据,或者从插在插槽201中的存储卡3等读出的编码影像声音数据,在主LCD屏202a或副LCD屏202b上放映影像,同时从扬声器SP或图中未示出的耳机输出声音。即,在耳机连接在耳机连接部203的状态,从耳机输出声音;在没有连接耳机的状态,从扬声器SP输出声音。是否连接有耳机的信息,通过接口215,从耳机连接部203传送给CPU209。另外,本实施例中,上述编码影像声音数据为比如MPEG4数据。
从存储卡3中读出的MPEG4数据通过PCMCIA接口220,以及系统总线213被供给MPEG4视频解码器204。另外,地面波数字调谐器230从设于主体2a或盖部2b上的图中未示出的天线接收地面波数字广播,取出该地面波数字广播所播送的MPEG4的位流数据,并传送给MPEG4视频解码器204或音频解码器(MPEG4-AAC)206。
MPEG4视频解码器204将影像数据供给图形控制器205,该影像数据通过将MPEG4的位流数据解码,求出量化系数或变化矢量,进行基于逆DCT转换或变化矢量的变化补偿控制等而获得。图形控制器205对影像数据(比如,R、G、B数据)进行色彩调整等处理。再有,图形控制器205还进行将由CPU209输出指示的文字等(菜单画面等)显示在LCD屏202a、202b上的OSD(屏幕视控系统:onscreen display)处理。音频解码器206将位流中的声音编码数据解码,生成声音数据。SDRAM210在进行MPEG4视频解码器204的上述处理时使用。
第1LCD控制器207a根据由图形控制器205提供的影像数据驱动主LCD屏202a。第2LCD控制器207b根据由图形控制器205提供的影像数据驱动副LCD屏202b。第1LCD控制器207a和主LCD屏202a组成的组与第2LCD控制器207b和副LCD屏202b组成的组,在任一组动作时,另一组都处于非动作状态,其控制由CPU209进行。D/A转换器208接收从音频解码器206输出的声音数据,进行D/A转换,生成模拟声音信号。
主体键214由有关收看或电话等的操作按钮或数字键、光标键等构成。对该主体键214的操作信息可通过接口215和系统总线213传送给CPU209。CPU209根据上述操作信息执行必要的处理。
另外,为了实现近距离无线网络,设有通信块216和接口217。进而,还具有FlashROM218和SDRAM219。用户的各种设定信息储存在比如FlashROM218中。电池221为二次电池,从图中未示出的充电器获得并存储电力。
CPU209还进行用于无线网络的处理、FlashROM218和SDRAM219的读取/照明控制等。而且,根据来自上述开闭检测开关231和耳机连接部203的耳机连接信息进行各种处理。
(1)在菜单画面上选择“设定”项目的话,则显示各种设定项目。选择这些项目中的“TV收看盖关闭时的设定”的话,则显示“盖关闭时始终TVOFF”、“盖关闭时输出声音”、“盖关闭时输出声音/辅助输出影像”、“盖关闭时输出声音/辅助输出信息”的项目。用户操作十字键(方向键),使光标移动到希望的项目上,按下决定键。CPU209将按下决定键时光标位置的项目作为用户设定信息存储在FlashROM218中。再有,当选择“盖关闭时输出声音”、“盖关闭时输出声音/辅助输出影像”、“盖关闭时输出声音/辅助输出信息”的项目时,显示“没有连接耳机时TVOFF”和“没有连接耳机也继续TVON”的选择项目,用户任选其一。
(2)当选择“盖关闭时始终TVOFF”时,CPU209检测出在数字广播收看过程中盖被关闭的话,则停止数字广播的接收处理和影像声音的输出(TVOFF)。在副LCD屏202b上显示电话待机画面。
(3)当选择“盖关闭时输出声音”,并且选择“没有安装耳机时TVOFF”时,CPU209检测出在数字广播收看过程中盖被关闭的话,则从耳机连接部203确认耳机的连接信息,如果为耳机连接状态,则停止输出数字广播的影像,同时继续输出接收的声音(耳机输出声音)。如果不是耳机连接状态,则停止数字广播的接收处理和影像声音的输出(TVOFF)。当选择“没有安装耳机也继续TVON”时,不从耳机连接部203确认耳机连接信息,继续输出声音(耳机输出声音或扬声器输出声音)。另外,由于不进行影像输出,故可停止向MPEG4视频解码器204、图形控制器205、LCD背景照明等通电。而且,在任一场合都在副LCD屏202b上显示电话待机画面。
(4)当选择“盖关闭时输出声音/辅助输出影像”,并且选择“没有安装耳机时TVOFF”时,CPU209检测出在数字广播收看过程中盖被关闭的话,则从耳机连接部203确认耳机连接信息,如果为耳机连接状态,则在副LCD屏202b上输出数字广播的影像,同时也输出接收的声音(耳机输出声音)。如果不是耳机连接状态,则停止数字广播的接收处理和影像声音的输出(TVOFF)。当选择“没有安装耳机时也继续TVON”时,则在副LCD屏202b上输出数字广播的影像,同时不从耳机连接部203确认耳机连接信息,继续输出声音(耳机输出声音或扬声器输出声音)。
(5)当选择“盖关闭时输出声音/辅助输出信息”,并且选择“没有安装耳机时TVOFF”时,CPU209检测出在数字广播收看过程中盖被关闭的话,则从耳机连接部203确认耳机连接信息,如果为耳机连接状态,则从存储器读出该节目的节目信息或附带数据的广播数据。例如,图3所示的那样,在副LCD屏202b上输出文字信息,同时也输出接收的声音(耳机输出声音)。如果不是耳机连接状态,则停止数字广播的接收处理和影像声音的输出(TVOFF)。当选择“没有安装耳机时也继续TVON”时,则在副LCD屏202b上输出数字广播的上述文字信息,同时不从耳机连接部203确认耳机连接信息,继续输出声音(耳机输出声音或扬声器输出声音)。并且,由于是显示文字,故也可停止向MPEG4视频解码器204的通电。
另外,为了进一步节省电力,也可在菜单项目中事先设置“当电池余量少时停止影像显示”或“用按钮操作停止影像显示”的选择项目。当选择“电池余量少时停止影像显示”时,电池余量低于规定的域值的话,则即使在通过主LCD屏202a或副LCD屏202b显示影像的状态下,也停止影像输出,并停止向其背景照明等提供电力。继续接收广播,继续输出接收的声音。当选择“用按钮操作停止影像显示”时,对该按钮操作,则即使在主LCD屏202a或副LCD屏202b显示影像的状态下,也停止影像输出,并停止向其背景照明等提供电力。继续接收广播,继续输出接收的声音。
再有,在上述实例中,表示了在上述盖部2b的内面侧具有主LCD屏202a,在外面侧具有副LCD屏202b的结构,但并不限于此。比如,具有盖部2b相对于主体2a按照可活动的方式设置且可紧凑化的形态,在上述盖部2b或主体2a上具有显示器,按照在紧凑化的状态看不到上述显示器的方式构成也可以(比如,盖部2b上仅具有主显示器的结构等)。进而,具有盖部2b相对于主体2a按照可活动的方式设置且可紧凑化的形态,在上述盖部2b和/或主体2a上适当设置主显示器和副显示器(比如,与上述实例相同的结构,或以折叠的形式在主体2a上设置主显示器,在盖部2b上设置副显示器的结构等),按照在紧凑化的状态看不到上述主显示器而可看到副显示器的方式构成也可以。另外,在折叠式的,且盖部旋转的类型中,可以形成在紧凑化的状态看不到上述主显示器的状态和可以看到的状态的两种状态,但在看不到的状态也可进行上述处理。而且,滑动型或旋转型即使在紧凑化状态也能看到显示器,但在这样的类型中,可以具有上述“当电池余量少时停止影像显示”或“用按钮操作停止影像显示”的功能。
另外,在上述实例中,是根据用户设定的,但即使没有这样的设定,盖关闭时的声音输出或副画面的影像和信息的输出也可以将安装有耳机为条件来进行,也可在没有连接耳机时进行TVOFF处理。
