Abstract
为在数字VTR连续重放的多个节目变化时执行视频和音频数据快速译码并添加表示节目变化的数据,MPEG视频和音频译码器分别译码多路分解器分离的MPEG视频和音频数据。数字接口在多路分解器和外部设备间传送和接收MPEG视频、音频和辅助数据并检测表示节目不连续性的特征位,微计算机执行控制以初始化缓存器。当微机在多路分解器传送的重放VAUX数据中检测到表示记录开始和记录结束位置的数据就通知数字接口。该接口产生标识在异步数据包的标题中节目变化的不连续特征位。
Description
技术领域
本发明涉及接收及译码数字广播的设备,特别涉及当未被译码的视频数据和音频数据由外部记录/重放设备输入时被执行的处理。
本发明还涉及记录和重放利用高性能技术、例如MPEG(运动图像专家组)技术进行编码视频和音频信号的设备,特别涉及添加表示重放节目的不连续或变速重放模式的标识数据的技术。
背景技术
近年来,在美国和欧洲,把例如由MPEG(运动图像专家组)开发的高性能编码技术应用于视频信号和音频信号的编码,然后利用通信卫星传送这些信号,在接收侧对它们进行译码的***已广泛使用。
在这些***中,在接收侧需要专用接收机/解调器。这种接收机从来自多个信道的数据在其中被多路复用的传送流中选择相应于所需信道的传送流、从所需信道传送流中分离出所需节目的视频和音频数据、以及译码被分离的视频和音频数据。
在这些***中,为了使接收机/译码器能够接收所需信道的传送流和分离所需节目的视频和音频数据,给被多路复用的传送流添加了PSI(节目专门信息)、EPG(电子节目指南)或SI(服务信息)。
已提出了在记录或重放视频及音频信号之前对它们进行编码的数字磁带录像机(以后称DVCR)。还提出了在这种DVCR上不译码这种数字广播视频数据和音频数据就记录/重放它们的概念(Yukio Kubota编辑的“数字视频记录器,实例”,第140-152页,Ohm公司,1995年8月25日)。
发明内容
本发明的目的在于:如果当上述类型的DVCR连续地重放多个数字广播节目时出现节目变化,就使在接收机/解调器中能够执行对视频数据和音频数据的快速译码,然后把这种数据输入给这样的接收机/解调器。
本发明的目的还在于:提供这样一种数字信号记录/重放设备和数字信号重放方法,在这种设备和方法中,当把在这种DVCR变速重放期间的输出输入给接收机/解调器并对其进行译码时,在视频数据和音频数据中不出现中断。
为了解决上述问题,本发明的数字信号处理器的特征在于包括:从包含多个多路复用信道的传送流中选择相应于任一信道的传送流的第一装置,根据在被选传送流中的辅助数据从该传送流中分离在任一所需节目中的视频数据和音频数据的第二装置,译码被分离的视频和音频数据的第三装置,把来自外部设备的视频数据、音频数据和辅助数据传送给第二装置并检测表示节目不连续的数据的第四装置,以及当第四装置检测到表示节目不连续的数据时,就初始化第三装置的第五装置。
另外,本发明的数字信号处理方法的特征在于由以下装置组成的数字信号处理器:从包含多个多路复用信道的传送流中选择相应于任一信道的传送流的第一装置,根据在被选传送流中的辅助数据从该传送流中分离在任一所需节目中的视频数据和音频数据的第二装置,译码被分离的视频和音频数据的第三装置,以及把来自外部设备的视频数据、音频数据和辅助数据传送给第二装置并检测表示节目不连续性的数据的第四装置,一旦第四装置检测到表示节目不连续性的数据就初始化第三装置。
根据本发明,一旦第四装置检测到表示节目不连续性的数据就初始化第三装置。
此外,本发明的数字信号记录/重放设备包括:输入/输出利用预定编码方案编码的数字信号的第一装置,把所述第一装置传送的所述数字信号记录在记录介质上的第二装置,再现被记录在所述记录介质上的所述数字信号的第三装置,以及检测在被所述第三装置重放的所述数字信号中的节目变化的第四装置,所述数字信号记录/重放设备的特征在于:一旦检测到节目变化,所述第四装置就把第一标识数据添加给所述第一装置输出的数字信号。
此外,本发明的数字信号重放方法的特征在于:当从记录介质中重放利用预定编码方案编码的数字信号并将其输出给外部设备时,一旦在重放数字信号中的节目发生变化,就向该数字信号添加第一标识数据。
在本发明的数字信号记录/重放设备和数字信号重放方法中,还可以在变速重放期间添加第二标识信号。
根据本发明,一旦检测到在被第三装置重放的数字信号中的节目变化,第四装置就向第一装置输出的数字信号添加第一标识数据。
如上所述,根据本发明,当由外部设备输入的节目发生变化时,视频数据和音频数据的译码可被迅速执行。
还有,如上所述,根据本发明,当在重放数据被输入和被接收机/解调器译码时出现节目变化,译码可被迅速执行。此外,当把变速重放期间的输出输入给接收机/解调器时,能够避免被译码视频数据和音频数据输出的中断。

具体实施方式
现在参看附图更详细地描述本发明。
图1是表示应用了本发明的数字信号处理器的结构的方框图。该数字信号处理器被称为IRD(集成接收机译码器)。
该数字信号处理器包括输入由下变频器(未示出)传送的RF信号和选择相应于所需信道的传送流的前端1,分离由前端1选择的所需节目的MPEG视频数据、MPEG音频数据和辅助数据的多路分解器2,以及暂存经多路分解器2输入和输出的数据的缓冲存储器3。
该数字信号处理器还包括译码被多路分解器2分离的视频数据的MPEG视频译码器4,译码被多路分解器2分离的音频数据的MPEG音频译码器5,把被MPEG视频译码器4译码的视频信号变换成为NTSC格式的视频信号的NTSC编码器6,把NTSC编码器6的输出变换成为模拟格式的D/A变换器7,以及把MPEG音频译码器5的输出变换成为模拟格式的D/A变换器8。向MPEG视频译码器4提供了暂存视频数据的缓冲存储器4a,向MPEG音频译码器5提供了暂存音频数据的缓冲存储器5a。
该数字信号处理器还包括控制该处理器的全部操作的微计算机9,控制面板10,以及数字接口11,该数字接口11把被多路分解器2分离的MPEG视频数据、MPEG音频数据和辅助数据传送给外部设备,或把从外部设备接收的MPEG视频数据、MPEG音频数据和辅助数据传送给多路分解器2。
前端1包括调谐器、QPSK解调器和纠错电路,它从包含多个多路复用信道的传送流中选择用户利用控制面板10指定的所需信道的传送流、执行QPSK解调和执行检错/纠错。
图2表示相应于一个信道的传送流的一实例。如该图所示,多个节目(在此用节目1至3来表示)在该传送流中被多路复用。在此,术语节目指假想的广播信道。在当前的日语广播中,这例如相应于诸如NHK卫星信道1和2这样的业务。
每一节目的数据按照预定长度(188字节)的数据包分组,每一数据包的开头有标题。PID(数据包标识)数据被分配给标题,以便标识数据。
通过多路分解器2把包含来自相应于被前端1选择的所需信道的传送流的辅助数据的数据包暂时写入到缓冲存储器3内。然后标识和分离在所需节目中的MPEG视频数据和MPEG音频数据,把视频数据传送给MPEG视频译码器4,把音频数据传送给MPEG音频译码器5。在图2中,节目2中的视频数据和音频数据被分离。
当执行这一分离时,对分配给数据包的PID(数据包ID)进行检查,当PID标识了所需节目的视频数据和音频数据时,就把这些数据分别传送给MPEG视频译码器4和MPEG音频译码器5。在图2中,分配给节目2的视频数据的PID是“xx”,而分配给节目2的音频数据的PID是“yy”。以下将描述在本数字信号处理器中用来建立节目编号和PID之间的相应关系的方法。
传送给MPEG视频译码器4的视频数据被存储在缓冲存储器4a内,并在方便时被读出和被译码。被译码的视频数据被NTSC变换器6变换成为NTSC信号制式,在被D/A变换器7变换成为模拟视频数据之后,它被提供给外部监视器(未示出)。传送给MPEG音频译码器5的音频数据被存储在缓冲存储器5a内,并在方便时被读出和被译码。在被译码的音频数据被D/A变换器8变换成为模拟音频信号之后,它被提供给监视器的喇叭(未示出)。
这样一来,就接收、译码并在监视器上显示了数字广播的视频信号和音频信号。
以下描述辅助数据。如上所述,给多路复用的位流添加PSI(节目专门信息)、EPG(电子节目指南)或SI(服务信息)。现在说明在欧洲采用的由MPEG规定的PSI和由DVB(数字视频广播)规定的SI。

以下将说明在本数字信息处理器内的微计算机9如何处理上述的PSI和SI。
首先,在数字信号处理器中,结合各种网络***设定常数和其它参数。把这种信息写入到网络信息表中去,网络信息表由此为传送流确定了调制方案、频率、位速率和纠错方法。在设定之后,把这种数据存储在微计算机9的EEPROM(未示出)内。
然后从EIT中搜索事件。在EIT中,给每一广播事件分配唯一的事件ID,节目名称和内容与它们的开始时间一道被写入,对于每一事件写入传送流ID和服务ID。根据EIT区分传送流ID,利用NIT内包含的传送流常数设置数字信号处理器,由此就选择了相应于所需信道的传送流。
以上所述是当所需信道的传送流在前端1内被选择时被执行的处理。以下说明当多路分解器2的输出被传送给MPEG视频译码器4和MPEG音频译码器5时,微计算机所执行的处理。
图3表示输入给多路分解器2的传送流的一实例以及在该传送流内的PAT和PMT的内容。图4表示缓冲存储器3的内部结构。图5表示这一处理的流程。以下的描述针对节目1被选择的情况。
首先,在图5的步骤S1中,通过多路分解器2把前端1的输出写入到缓冲存储器3中去。在缓冲存储器3中,如图4所示地为各数据定义了存储区3A-3C,不同类型的数据被写入这些区。
然后,在步骤S2中,从被写入缓冲存储器3的辅助数据区3C的辅助数据中搜索PAT。为了执行这一处理,可以搜索PID为0的数据包。如图3(2)所示地把每一节目的PMT的PID(在此,PMT1的PID是“cc”,PMT2的PID是“dd”)写入PAT中去。
然后搜索PID为“cc”的数据包。这样就检测到相应于节目1的PMT1。如图3(3)所示,MPEG视频数据、MPEG音频数据和节目1的ECM的PID被写入PMT1。
因此,为了收看节目1,就从缓冲存储器3的MPEG视频数据区3A中读出PID为“aa”的数据包并通过多路分解器2把其传送给MPEG视频译码器4,从MPEG音频数据区3B中读出PID为“ab”的数据包并通过多路分解器2把其传送给MPEG音频译码器5。在这一过程中,如图2所示地发送不带标题的数据。还利用被写入在PID为“xx”的数据包内的ECM信息来译码扰频。
为了收看节目2,按照同样方式搜索PID为“dd”的数据包。在这一数据包中,视频数据、音频数据和ECM的PID如图3(4)所示地被写入。从缓冲存储器3的MPEG视频数据区3A中读出PID为“ba”的数据包并将其传送给MPEG视频译码器4,从MPEG音频数据区3B中读出PID为“bb”的数据包并将其传送给MPEG音频译码器5。还利用被写入在PID为“zz”的数据包内的ECM信息来译码扰频。
以上的描述针对当前端1输入的传送流被译码时所执行的普通处理。图1的数字信号处理器还能够通过数字接口11把被多路分解器2分离的MPEG视频数据、MPEG音频数据和辅助数据输出给诸如DVCR这样的记录/重放设备。此外,该处理器还能够利用数字接口11接收由外部记录/重放设备输出的MPEG视频数据、MPEG音频数据和辅助数据。现在描述这一处理。
首先,描述从数字接口11把多路分解器2的输出传送给外部设备的微计算机9的处理。由于这一处理的大部分与上述普通处理相同,所以在此将只说明不同点。
MPEG视频数据和MPEG音频数据与包标题一起被传送给数字接口11。换句话说,当微计算机9从缓冲存储器3中读出时,它读出各个标题数据,并通过多路分解器2把其传送给数字接口11。
PSI和SI也与标题一起被传送给数字接口11。但是,PAT只留下由具有选定的节目编号的PMT规定的PID,删除其余部分。例如,当节目1被选择时,只有PMT1的PID(在图3的情况下是“cc”)留下,其余部分被删除。
传送给数字接口11的数据被传送给外部设备。该数字接口是例如以IEEE-1394为基础的,在这种情况下,数据在其被输出之前被***到符合IEEE-1394的异步数据包中。数字接口11输出的异步数据包被传送给外部DVCR等。然后从该异步数据包中提取数据,在记录***中增加纠错编码,在对数据进行了信道编码之后就将其记录。
以下描述按照上述方式重放被记录在DVCR中的数据并将其输入给数字信号处理器的情况。外部DVCR把重放数据输入给被输出的异步数据包。该异步数据包被输入给数字接口11,提取原始的MPEG视频数据、MPEG音频数据和辅助数据,并通过多路分解器2把这些数据写入到缓冲存储器。
被写入缓冲存储器3的MPEG视频数据和MPEG音频数据的处理与上述从前端1输入的传送流中的数据的处理相同。相反地,微计算机9如下所述地对写入缓冲存储器3的PSI和SI进行处理。
不作改动地使用PAT和PMT。如上所述,当数据从数字信号处理器输出至外部DVCR时,只有规定了相应于根据PAT选择的节目编号的PMT的PID被留下,其余数据被删除,因此,只有规定了当前正在被输入的节目编号的PMT的PID被写入在外部DVCR输入的数据内的PAT中去。因此,通过检查该PAT搜索PMT,就能够读出当前正在被输入的节目的MPEG视频数据和MPEG音频数据。被读出的MPEG视频数据和MPEG音频数据通过多路分解器2传送给MPEG视频译码器4和MPEG音频译码器5,然后被按照与对由前端1输入的数据进行处理的方式相同的方式被进行处理。
至于EIT,只有在被写入PAT的节目内的实际或当前数据被译码,其余数据被忽略。此处的术语“实际”指在被选信道中的传送流,“当前”指被选节目正在被广播这一事实。
至于RST,只有与被写入PAT的节目有关的元素被译码,其余部分被忽略。至于SDT,只有在被写入PAT的节目中的实际元素被译码,其余部分被忽略。
需要NIT来设置前端1,但是,由于在多路分解器2中不需要它,所以将其忽略。BAT也被忽略。
至于TDT,当输入来自外部记录/重放设备的重放信号时,在该设备的该重放信号内的TDT表示视频记录当时被执行的时间,不是当前时间,因此TDT也被忽略。当来自外部设备的输入信号不是重放信号时,TDT就表示当前时间,对其译码。换句话说,根据TDT是否表示当前时间,处理是不相同的。因此,如果给来自外部设备的输入信号增加表示TDT是否表示当前时间的数据将是方便的。这样就避免了在复位内部时钟时设定错误的时间。
现在说明从外部DVCR连续地输入多个节目的情况。微计算机9检查PAT来搜索PMT,并通过检查PMT来读出在由外部DVCR正在输入的节目中的MPEG视频数据和音频数据。但是,当该外部DVCR连续地输出多个节目并对节目进行转换时,微计算机9就检查PAT以便搜索PMT,被转换节目的MPEG视频数据和MPEG音频数据不能够被读出。还由于在MPEG视频译码器4和MPEG音频译码器5中使用过去的数据,所以除非保留在缓冲存储器4a和5a内的转换之前的节目数据被消除,否则就不能够执行正确的译码。
同样地,至于SI,当利用不同的传送流转换节目时,缓冲存储器3内的SI也必需被更新。
因此,根据该实施例,当DVCR重放的节目变化时,标识这种变化的特征位就被附加给异步数据包的标题。图6是表示异步数据包的格式的图示。当标记字段的2个位是012时,就在数据字段的开头***2个四倍字节(quadlet)的公共异步数据包标题(以后称为CIP标题)。标记的值被定为012,以便处理来自数字视频设备或数字音频设备的实时视频和音频信号数据。
图7表示标记=012时的CIP标题。图8表示在CIP标题中指定FMT(格式类型)的一实例。如图8所示,DVCR用FMT=0000002来规定,MPEG信号传送格式用1000012来规定。根据这一实施例,不连续特征位被分配给FDF(根据相关字段)的位b0。
当DVCR重放信号中的传送流不连续时,就把不连接特征位置为“H(高)”电平一段预定的时间(例如1秒)。具体来说,当视频数据在DVCR中被记录时,表示记录的开始位置(REC START)和结束位置(REC END)的视频辅助数据(VAUX数据)与该视频数据一道被记录。因此,一旦在重放期间检测到这种辅助数据,就把不连续特征位置成“H(高)”电平。
根据这一实施例,一旦DVCR模式从停止(STOP)改变为重放(PB),上述不连续特征位就被置为“H(高)”电平。因此,即使从中间重放一节目,也能够清除缓冲存储器4a、5a内的数据和更新缓冲存储器3内的SI。
此外,根据这一实施例,变速重放特征位被附加给FDF的位b1。当DVCR操作模式是慢速或提示/检查模式时,就把这一特征位置为“H(高)”电平。在这种变速重放期间,只有MPEGI图像是有效数据,所以缓冲存储器4下溢,在下一I图像被译码之前,MPEG视频译码器4的输出截止。因此,数字信号处理器具有这样的结构,即一旦损坏了这一特征位,就从MPEG视频译码器4输出最后被译码的I图像,直到下一I图像被输出为止。
图9是表示当有外部输入时微计算机9执行的处理的流程图。
首先,微计算机9判断是否有外部输入(步骤S11)。根据前面板10的输出作出是否有外部输入的判断。
然后,判断是否检测到不连续特征位(步骤S12)。这一判断基于数字接口11是否检测到图7所示的不连续特征位。一旦检测到不连接特征位,就更新缓冲存储器3内的PAT、PMT和SI,并向MPEG视频译码器4和MPEG音频译码器5发送清除缓冲存储器4a、5a内的数据的命令(步骤S13)。
然后,判断是否检测到变速重放特征位(步骤S14)。与步骤S12的判断类似,这一判断基于数字接口11是否检测到图7所示的变速重放特征位。一旦检测到变速重放特征位,就命令MPEG译码器4继续输出最后被译码的I图像。
图6是表示异步数据包的格式的图示。当标记字段的2个位是012时,2个四倍字节的公共异步数据包标题(以后称为CIP标题)就被***数据字段的开头处。把标记的值置为012,以便处理来自数字视频设备或数字音频设备的实时视频和音频信号数据。图7表示标记=012时的CIP标记。图8表示在CIP标题中指定FMT(格式类型)的一实例。
根据这一实施例,FMT=1000012并规定了MPEG信号传送的格式。MPEG数据被输入给在图6所示CIP标题之后的数据块。
图10是表示应用了本发明的DVCR的结构的方框图。该DVCR具有编码和记录/重放模拟视频信号的功能,还具有记录/重放MPEG数字信号的功能。
首先描述模拟视频信号的记录/重放。
为了记录模拟视频信号,该DVCR包括数字化视频信号的A/D变换器21、对A/D变换器21的输出执行例如DCT(离散余弦变换)这样的数据压缩、量化和变长编码的数据压缩编码电路22、以及成帧数据压缩编码电路22的输出的成帧电路23。
此外,该DVCR还包括组合成帧电路23的输出和由以下描述的信号处理微计算机28产生的视频辅助数据(VAUX数据)的多路复用器24、给多路复用器24的输出增加纠错码的纠错码增加电路25、以及记录/调制纠错编码电路25的输出的信道编码器26。
该DVCR还包括根据用户操作产生视频信号TV信道和诸如记录日期及时间等这样的数据信号的模式处理微计算机27、以及根据模式处理计算机27的输出产生VAUX数据的信号处理计算机28。此处的VAUX数据包括TV信道、记录日期和时间、磁带上的记录开始(REC START)位置和记录结束(RECEND)位置。
图11表示纠错码增加电路25输出的一个磁道的数据的格式。如图所示,视频数据和VAUX数据按照90字节的块单元来组织。这些数据在信道编码器26中被记录/调制,被记录放大器(未示出)放大,并被磁头(未示出)记录在磁带上。在实际的DVCR中,视频数据、VAUX数据、音频数据和子代码数据按时分方式被记录在磁道中。
以上描述的是模拟视频输入信号的编码和记录。以下描述对被记录的视频信号的再现。
该DVCR包括对重放放大器(未示出)放大的数据进行波形均衡和重放数据时钟的重放电路29、对重放电路29输出的数据进行记录解调的信道译码器30、对信道译码器30的输出进行错误校正的纠错电路31、分离纠错电路31的视频数据和VAUX数据的多路分解器32、分离该视频数据的帧的解成帧电路33、对解成帧电路33的输出执行诸如变长码译码、逆量化和逆DCT这样的处理的数据压缩译码电路34、以及把数据压缩译码电路34的输出变换成为模拟格式并由此把其变换成为模拟视频信号的D/A变换器35。被多路分解器32分离的VAUX数据传送给信号处理器微计算机28,再从该信号处理器计算机28传送给模式处理器微计算机27。
以下描述对外部设备输入的编码信号的记录/重放。该DVCR具有数字接口36。该数字接口36的结构与在图1的接收机/解调器内的数字接口11的结构相同。IEEE-1394数据包传送给图1的数字接口11,并从该接口接收IEEE-1394数据包。
以下描述对数字接口36输入的MPEG数据的记录。这种MPEG数据通过图1的接收机/解调器的数字接口11在异步数据包中被输入和被传送。
首先,分离来自在数字接口36中的异步数据包的MPEG数据,即MPEG视频数据、MPEG音频数据和辅助数据。被分离的数据通过开关SW1传送给多路复用器24、与信号处理器微计算机28输出的VAUX数据进行多路复用,并被纠错码增加电路25变换成为图11的格式。换句话说,MPEG视频数据、MPEG音频数据和辅助数据都被记录在视频数据记录区内。纠错码增加电路25之后的处理与上述模拟视频信号的记录相同。
以下描述在重放MPEG数据期间的处理。直到把重放数据输入给多路分解器32,重放期间的处理与视频信号重放期间的处理相同。输入给多路分解器32的重放信号被分离成为MPEG数据和VAUX数据。MPEG数据通过开关SW2传送给数字接口36。VAUX数据传送给信号处理微计算机28。
在数字接口36内,把图6和图7所示的标题添加给MPEG数据,并输出给外部设备作为异步数据包。该异步数据包输入给接收机/解调器的数字接口11,提取原始MPEG视频数据、MPEG音频数据和辅助数据,并通过多路分解器2写入给缓冲存储器3。
上述的标记如图12所示。其中的NP是正常播放数据,而TP是三倍速播放数据。NP1-NP2表示正常播放节目已发生变化。
