具体实施方式
下面根据图1至图5来说明本发明的实施例。
该实施例的广播视听系统,如图1和图2所示的那样,由外置型外围装置1和携带型视听装置2所构成。在该系统中,外置型外围装置1接收广播(在该实施例中,为地面波模拟广播)。根据该接收的广播,把编码图像·声音数据存储到插入插槽101的存储卡3(例如,小型高速卡(商标)和多媒体卡(商标)等)中。外置型外围装置1的本体部1a是纵向设计,在其下部具有脚部1b,防止倒置。而且,在外置型外围装置1上设有电源按钮和与视听相关的操作按钮(播放/暂停、停止、快进),但是,没有设置用于频道选择的操作按钮类。而且,在外置型外围装置1的本体部1a的前方形成容纳凹部1c,能够在该容纳凹部1c中插入携带型视听装置2来进行安装。在该安装状态下,携带型视听装置2从外置型外围装置1接受充电。
携带型视听装置2具有大致方形的扁平形状,成为由电池驱动的构成。携带型视听装置2从插入插槽201的存储卡3读出编码图像·声音数据,在液晶显示屏202上映出图像,同时,从耳机203输出声音。可以在液晶显示屏202上粘贴触摸屏211,通过触笔等来进行面板操作,提供所希望的指示。而且,把与视听相关的操作按钮(播放/暂停、停止、快进、音量等)设在壳体部上。
下面根据图3来对外置型外围装置1和携带型视听装置2的电路构成进行详细说明。
首先,对外置型外围装置1进行说明。调谐器102接收地面波模拟广播,输出该广播接收信号。调谐器102的驱动指令和用于接收任意广播的选台信息(频道信息)从CPU 110通过I/O(输入/输出)电路103和系统总线104来提供。CPU 110通过系统总线104、PCMCIA接口105以及插槽101从上述存储卡3收取由用户所进行的选台指令信息(指定频道信息、指定时间信息等)。开关106具有输入上述广播接收信号的输入部和输入外部信号的输入部,选择其中之一的信号,提供给A/D变换电路107。
A/D变换电路107把模拟信号变换为数字信号,提供给MPEG4(Moving Picture Experts Group4)编码器108。MPEG4编码器108按照MPEG4例如分别记述图像中的背景和背景中的人物作为各个对象,为了处理该任意形状的各个对象,附加形状信息,同时,与MPEG2相同,进行DCT处理和运动矢量处理,生成视频分组,输出使其连续的比特流(编码图像·声音数据)。对于声音进行预定的编码,把该声音编码数据装入上述比特流。SDRAM 109用于MPEG4编码器108的上述处理。
MPEG4编码器108输出的比特流通过系统总线104、PCMCIA接口105及插槽101而存储到存储卡3中。
设置两组插槽101和PCMCIA接口105。可以在插槽101中装入上述存储卡3以及PHS数据卡4等。
充电电路113具有把来自工频电源的交流电直流化的电路,如图1所示的那样,当携带型视听装置2装入外置型外围装置1中时,通过未图示的充电端子进行向携带型视听装置2的充电功率供给。
CPU110除了进行上述调谐器102的动作控制和把MPEG4编码器108的输出存储到存储卡3中的处理(录像处理)之外,还进行当PHS数据卡4装入插槽101中时的数据发送接收、根据该数据的各个功能部的控制、FlashROM 111和DRAM 112的读/写控制等。
图4是简单表示外置型外围装置1的录像处理内容的流程图。当外置型外围装置1的电源开关被按下时(可以设置录像开始开关,判断与其相对应的操作),判断存储卡3的有无、选台信息的有无(步骤S1,S2,S3),如果都是YES,判断选台信息中的录像开始时刻与现在时刻是否一致(步骤S4),如果成为录像开始时刻,执行接收处理,进行编码图像·声音数据的生成和向存储卡3的记录(步骤S5),如果成为录像结束时刻(步骤S6中的YES),结束录像处理。
下面说明携带型视听装置2。在存储卡3中所存储的MPEG4比特流数据经过PCMCIA接口220以及系统总线213而提供给MPEG4解码器204。MPEG4解码器204对上述比特流数据进行解码,求出量化系数和运动矢量,根据逆DCT变换和运动矢量,进行运动补偿控制等,把由此得到的图像数据提供给图形控制器205。图形控制器205对图像数据(例如,R,G,B数据)进行色调调整等处理。而且,图形控制器205进行在液晶显示屏202上显示由CPU209所输出指示的文字等(操作按钮和菜单画面等)的处理。音频解码器206从MPEG4解码器204收取比特流中的声音编码数据,进行解码而生成声音数据。SDRAM 210用于MPEG4解码器204的上述处理。
LCD控制器207根据由图形控制器205所提供的图像数据来驱动液晶显示屏202。而且,D/A变换器208收取从音频解码器206所输出的声音数据,进行D/A变换,生成右(R)声道的模拟信号和左(L)声道的模拟信号,提供给耳机203。
与触摸屏211相对应的操作信息通过专用接口212和系统总线213提供给CPU 209。CPU 209根据上述操作信息与液晶显示屏202上的操作按钮等的显示的对应关系,来把握指令内容,执行必要的处理。
本体键214相当于与上述视听相关的操作按钮(播放/暂停、停止、快进)。与该本体键214相对应的操作信息通过接口215和系统总线213提供给CPU 209。CPU 209根据上述操作信息执行必要的处理。
而且,为了能够使用无线网络,而设置通信块216和接口(例如,Bluetooth(商标)等)217。而且,设有FlashROM 218和DRAM219。电池221是二次电池,从外置型外围装置1得到电力供给,并进行蓄电。
CPU 209进行用于无线网络的处理、当在插槽201上装入PHS数据卡4时的数据发送接收、根据接收数据的各功能部的控制、进行FlashROM 218和DRAM 219的读/写控制等。而且,当用户使用触摸屏211等来进行接收节目的指定(频道及时刻指定)时,进行把该信息存储到存储卡3中的处理。
图5是简单表示携带型视听装置2的重放处理的流程图。当携带型视听装置2的重放按钮被置于ON时,判断存储卡3的有无、编码图像·声音数据的有无(步骤S11,S12,S13),如果都是YES,判断停止按钮和暂停按钮的操作状态(步骤S14),如果不是停止操作,从存储卡3读出编码图像·声音数据(步骤S15),如果结束编码图像·声音数据的重放(步骤S16中的YES),结束重放处理。
如上述那样,能够用外置型外围装置1接收广播,把MPEG4的比特流数据存储在存储卡3中,携带型视听装置2对在上述存储卡3中所存储的上述比特流数据进行解码,而能够在液晶显示屏202上进行图像显示,因此,即使在携带型视听装置2中不设置广播接收功能,在广播之后,也能在例如外出时进行视听。而且,由于是携带型视听装置2,则即使不单独设置充电器,也能用外置型外围装置1向携带型视听装置2进行充电。而且,用外置型外围装置1向存储卡3提供作为接收哪个广播的信息的选台信息,因此,不需要在外置型外围装置1中设置用于由用户操作所进行的频道选择的按钮等。
而且,虽然没有图示,但也可以在外置型外围装置1中设置与设在携带型视听装置2中的通信块216和接口(例如,Bluetooth(商标)等)217相同规格的通信块和接口,可以在外置型外围装置1与携带型视听装置2之间实现无线网络。由此,能够从携带型视听装置2通过无线网络向外置型外围装置1提供选台信息。而且,通过这样的无线网络,能够从外置型外围装置1向携带型视听装置2发送MPEG4的比特流数据,由此,能够使用携带型视听装置2来实时收视正在广播的图像。而且,可以通过有线网络来连接外置型外围装置1和携带型视听装置2,与上述相同来进行选台信息和比特流数据的发送。而且,可以取代从外置型外围装置1向携带型视听装置2发送MPEG4的比特流数据的方案,而从外置型外围装置1经过AV端子(或者S端子和D端子等)向携带型视听装置2发送复合图像信号(也可以是分量图像信号)。
在外置型外围装置1的容纳凹部1c中安装有携带型视听装置2的状态下,实时地视听广播,如图1所示的那样,当携带型视听装置2的操作按钮被外置型外围装置1所隐藏时,可以在外置型外围装置1上配置操作按钮,以便于进行与对应的操作按钮相同的操作,在外置型外围装置1侧能够操作携带型视听装置2。与外置型外围装置1的操作按钮相对应的操作信息能够使用无线网络和有线或者有线网络而向携带型视听装置2侧进行发送。而且,可以在外置型外围装置1中设置扬声器,从外置型外围装置1的扬声器输出接收广播的声音,在携带型视听装置2的液晶显示屏202上显示图像。
而且,当外置型外围装置1接收地面波数字广播时,可以不需要MPEG4编码器108。使用无线网络和有线网络来向携带型视听装置2侧发送用于由地面波数字广播所发送的EPG(ElectronicProgram Guide)显示的数据,由该携带型视听装置2的液晶显示屏202进行EPG显示,可以由存储卡和无线/有线网络来向外置型外围装置1提供在该EPG上所指定的节目的选台信息。
