Abstract

一种发射、接收和传播与数字数据信号组合的节目数据信号的装置和方法。本发明最好包括30个数字音频信号(10-1至10-30),与各种节目信息一起复用,并由卫星(50)把组合的信号发送给接收站(60)。接收站多路分解(70)该信号,并经电缆分配系统把它们送至用户的数字音乐调谐器(100)。再多路分解(143)和译码(147)该信号,使数字音频信号可转换为模拟信号(160)供收听,而数据信号传播给用户(180)。

Description

发送、接收和传播数字内容数据信号的方法和装置
本申请涉及数字信号传输领域,更具体地说,它涉及发送带有节目内容数据的数字信号,以便收听者/观看者可以在他们收听或观看演出时看见节目内容数据的显示,而不中断演出。
目前,节目内容信息,如歌名,演员,录制标记等是通过播音员的录音薄膜(disc Jockey)(DJ)传播(Communicated)到用户/收听者的。在用广播方式发送视频节目的情况下,视频主题消息在节目之间和在节目中断期间出现。在许多有奖服务的情况下,不希望中断节目来显示节目内容信息。而且也不希望在节目或音乐的选择之间有任何形式的播音员或DJ出现。
在一些服务中,这样的播音员或节目中断可能是不希望的。然而,最希望的是传播节目内容的信息。如果用户没法知道传送乐曲的名称,作曲者或演员,由于预订的取消,会使用户失望和可能的收益的损失。对于音乐行业,录制标记的识别和识别号对于唱片的销售是关键的。目前,观看有奖视频节目的用户为了进行识别,必须借助一个单独的表,调谐到一个不同的频道,或者一直等到这个节目结束。
同样地,电缆电视行业目前正在采用只有音频的服务。节目内容的信息打印在一张单独的表上。这些电缆“无线电台”可以连续顺序地播放音乐的精选,而没有广告中断。这些服务可以不用“录音薄膜”识别音乐或其它的精选。在本发明中,取而代之的是数据信道将包含有关正在播放的音乐的信息。
在本发明的一个实施例中,这个数据的显示被想象成称为“电子DJ”。这种显示器可以装在用户终端中,或者它可以是接到该终端的后面板上的一个端口的独立的显示单元。
这种显示器的问题在于,除非它们非常大因而很贵,它们就不能很容易地放在收听者的阅读距离内。该显示器的长电缆在一般的起居室内布线将是困难的,而且我们只需要看接线的遥控VCR的成功,确信这种限定的显示器不是最佳的。
无线遥控已经给用户产品的控制带来了很大的方便。具有液晶显示的高度集成的遥控器已经有了。承担多个其它控制功能的可编程和万能的“学习”遥控器可以得到了。这些遥控器相互接收信息,并向用户显示可用的功能。
只要该电台不能识别该段音乐,在电台中欣尝一段音乐可能是一个无效的经历。对于音乐爱好者来说,得到如音乐名称,作曲者,演员和录制标记这样的信息是极其重要的。没有这些信息,服务将降低到一般的背景音乐的水平。
这些问题和所涉及的发送与提供节目内容数据的显示问题通过本发阴的原理解决了。在这些原理的促进下,本发明的一个目的是向用户提供节目信息而不中断节目。
本发明的一个目的是发送和提供传送给用户的数字音频的节目信息,该节目信息与数字音频组合起来。
本发明的另一个目的是向视频信息用户提供节目数据。
本发明的另一个目的是向通过遥控单元传播信息的用户提供节目信息。
本发明的另一个目的是提供一个系统,在该系统中,节目信息与经卫星,同轴电缆或其它方式发送给用户的数字音频/视频信号组合起来。
本发明的另一个目的是向失去能力的用户提供相应于音频/视频信号的节目数据。
根据这些和其它的目的,按照本发明的编码装置包括:产生数字信号的多个装置;产生多个节目数据信号的多个装置,每个节目数据信号相应于一个数字信号;以及至少一个编码装置;连接到多个产生数字和节目数据信号的的装置,用于对多个节目数据信号与多个数字信号进行编码,产生多个组合的数字与节目数据信号。
另外,根据这些和其它的目的,公开了一种把节目信息编码为一个数字数据流的方法,它包括以下步骤:产生多个数字信号;产生多个节目数据信号,每个节目数据信号相应于一个数据信号;以及对多个节目数据信号与多个数字信号进行编码,产生多个组合的数字与节目数据信号。
相反地,根据上述和其它的目的,公开了一个传播节目信息的装置,该信息来自包含多个数字与节目信息信号的信号,相应于数字数据的轨迹,该装置包括:第一接收装置,用于接收包含多个数字信号和多个节目数据信号的编码信号,每个节目数据信号相应一个数字信号;至少一个选择装置,连接到第一接收装置,用于从所接收的编码信号中选择一个数字信号和一个相应的节目数据信号;至少一个译码装置,连接到该选择装置,用于对所选择的一个数字信号和那个相应的节目数据信号进行译码,以便从所选的一个数字信号中分离出相应的节目数据信号;发送装置,连接到该译码装置,用于发送那个相应的节目数据信号;第二接收装置,连接到该发送装置,用于接收那个相应的节目数据信号;以及传播装置,连接到第二接收装置,用于传播那个相应的节目效据信号。
类似的,根据上述目的,公开了传播节目信息的一种方法,该信息相应于从包含多个数字与节目信息的信号来的轨迹,该方法包括以下步骤:接收含有多个数字信号和多个节目数据信号的编码信号,每个节目数据信号相应一个数字信号;从接收的编码信号中选择一个数字信号和那个相应的节目数据信号;对选出的一个数字信号和那个相应的节目数据信号进行译码,以便从所选的一个数字信号中分离出相应的节目数据信号;发送一个相应的节目数据信号给一个通信机;接收所发送的一个相应的节目数据信号,并且经过通信机传播所接收的一个相应的节目数据信号。
最后,根据本发明的目的,公开一个传播相应于数字数据的节目信息的手持装置,它包括:用于接收相应于一个数字轨迹的节目数据信号的接收装置;处理装置,连接到该接收装置,用于处理所接收的节目数据信号;以及通信装置,连接到该处理装置,用于传播处理的节目数据信号。
根据本发明的通信装置可以用标准的遥控形式,印具有某种类型显示器的手持单元。该显示器可以是液晶的或其它适用技术的显示器。根据本发明在一个遥控单元中有显示器的好处是显示器的费用不需包含在基本单元中。显示器可以是附加值的额外费用。因此它可看成是一个增加收益的装置,或者使该服务能提供那些没有要求的的性能的装置。
根据本发明的通信装置也可以使用安装在桌面的单元的形式。它可使用比手持遥控器可能用的显示器更大的显示器。它也可用交流电源代替电池,因此对更亮和更大的显示器供电,更适合低亮度观看。控制和显示功能可以分为两个独立的单元。
无论什么时候改变节目,基本用户终端都能自动地更新该远程显示/控制单元。但是,这可能产生短暂的间隔,在该间隔期间使用其它的遥控器可能被中断。因而,该通信可以这样构成,对于从基本用户单元发送的信息,它必须由远程单元轮询。存储器即可用在基本单元中也可用在远程单元中来存储先前选择的信息。这个信息可能会根据用户的请求再调用。
在基本用户终端和远程单元之间的通信链路可以使用射频,红外线。可见光,经过空气的声音传输,或者其它的无线装置。这个概念也可以扩展为在住户的电力线,电话线,同轴电缆,光缆或者其它不是把电缆直接连接到该基本单元的装置上传递该信息。
本发明的这些及其它优点通过从结合附图的下面详细描述可以更为清楚了。

参照图1,它描述了本发明的整个系统的方框图。本发明将就发送具有节目数据的音频信号进行描述。但是,本领域的普通技术人员会认识到,本发明可以不发送具有相应节目数据的音频,而发送具有相应节目数据的下面的任一个:电视、游戏,软件,视频,和其它音频/视频或软件信息的组合。
高密度盘(CD)唱机10—1至10—n给本发明提供了多个数字音频信号。这些CD唱机可以是所谓的“投币式自动电唱机”(jukebox)型的,该唱机可以存储和进入多达60个或更多的高密度盘。
来自CD唱机10—1至10—n的数字音频信号输入到编码器20—1至20—n,这些编码器将参照图3进行详细描述。控制器和音乐数据库30—1至30—n控制CD唱机10—1至10—n的输出和这些唱机中高密度盘的各个选择,并且也提供一个数据库,该数据库包含相应于与包含在高密度盘上的轨迹一一对应的节目数据。这个节目数据包括在高密度盘上的每首歌曲的名称,轨迹,演员,出版者,作曲者,歌曲的识别和播放时间的信息组。这些节目数据信号还包括其它有关描述包含在一张高密度盘上的特殊轨迹的信息,正如本领域普通技术人员可以意识到的。例如,如果这个信息是历史的音频数据,关于时间和地点的,这种数据是第一次想到或发送的信息也可以包括在这个节目信息中。另外,如果传送的数字信号包含视频信号,那么相应的节目数据信号可能涉及正在发送的这个视频节目,如歌名,演员,导演,出版者,年份或其它有关的信息。
由CD唱机10—1至10—n输入的多个数字音频信号与由控制器和音乐数据库30—1至30—n输入的节目数据信号在编码器20—1至20—n中进行组合。然后,从编码器20—1至20—n来的组合信号被输入到复用器40,复用器40把这些信号组合为串行数字数据流。
附加的信号可以与数字音频和节目信息信号进行组合。用户控制器45包含可接收本发明产生的数字音频数据的各种用户的信息。存储在用户控制器45中的用户信息在复用器40中与数字音频和节目数据信号进行复用,产生包含数字音频,节目信息和全国用户信息的串行数字数据流。
来自复用器40的串行数字音频/节目数据流被输入到数字卫星发射机50,并经过卫星广播到数字卫星接收机60 。但是,本领域的普通技术人员可以知道,任何传送系统,不仅是卫星传输,都可以使用,例如电缆电视(CATV),微波散布(MDS或MMDS),电活系统,陆地广播和其它的同轴或光缆线路。
前述的发射机部分将参照图2作更全面的描述,而下面的接收机部分将参照图4作更全面的描述。数字卫星接收机60把数字数据传送给前端处理器70,它依次转换并传送信息给数字电缆调制器75。然后,数字音频数据与来自其它的电缆调制器的信号在加法电路80中相加,并且经过电缆分配系统发送。
该电缆分配系统包括用于提升该信号并对任何线路损耗补偿的线路放大器90。系统抽头85把组合的信号引导到用户的房屋,并进入数字音乐调谐器100 。数字音乐调谐器100将参照图5进行更全面的描述,它选择含有数字音频和节目数据信号的频道。另外,数字音乐调谐器100还从节目信息信号中分离出数字音频信号。该数字音频信号被变换为模拟信号,放大,并在一个用户音频电子装置上输出,而节目信息信号则被处理并传送给一个本地显示器或远端使用的信息显示器200。该信号的多路分解和译码将参照图6进行更全面的讨论。然后这些显示器向用户传播相应于该用户目前正在收听的音频轨迹的特殊节目信息。该远端音乐信息显示器将参照图7进行更全面的描述。
参见图2,它描述本发明的播音室和发射机,或上行链路部分的方框图。高密度盘唱机10—1至10—n是由微计算机15—1至15—n驱动的。微计算机15—1至15—n可以是IBM AT型的微计算机。这些微计算机由演播顺序主控制器30—1至30—K依次进行控制。这些主控制器30—1至30—K包括一个含有上述节目信息的数据库。这些主控制器最好是IBM PS/2型微计算机或包括386型微处理器的其它计算机。
由CD唱机10—1至10—n输出的数字音频与由主控制器30—1至30—K提供的节目信息一起输入到编码器20—1至20—n。编码器20—1至20—n把数字音频信号与节目数据信号进行组合,并把组合信号输出到系统数据复用器40—1和40—2 。最好是30个编码器20—1至20—30的输出被输入给复用器40—1和40—2,在那里信号进行时分复用。复用器40—1和40—2可以包括纠错编码,使用如汉明编码或BCH(BoseChaudhuri Hocquenghen)编码,或者本领域普通技术人员知道的其它纠错/编码方法。
计费系统47包括本发明的用户信息和全国控制信息,并且可以包括一个IBM PS/2型微计算机。该用户信息和其它的计费系统数据可以包含在计费系统47的大数据库中。典型的计费系统数据例如可以包括用户的身份,位置等和他们目前的计费状态。从计费系统47来的计费系统信息被输入给系统管理器数字音频控制器45。系统管理器45最好包括Scientific Atlanta公司制造的8500系列的系统管理器或类似的产品。系统管理器数字音频控制器45控制主控制器30—1至30—K。另外,系统管理器45也可以把从计费系统47中的用户数据库来的用户数据输入给复用器40—1和40—2 。
通过复用器40—1和40—2,用户信息可以与数字音频和节目信号进行组合。复用器40—1和40—2给所有的译码器20—1至20—n及卫星激励器53—1和53—2提供主时钟。复用器40—1和40—2的输出是每秒34兆比特(Mbps)的数据流,它包括30个编码器20—1至20—30输出的最好的30个频道。
继电器电路43提供故障保护,以便有故障时,使该系统从复用器40—1转换到复用器40—2 。复用器40—1和40—2的输出是两条同轴电缆,用于加和减平衡连接。这些平衡同轴电缆用在复用器40—1和40—2的输出至卫星发射和接收电子设备。来自复用器40—1的组合信号通过继电器43进入光纤发射机49。光纤发射机49把来自播音室的信号传送到发射机站,并且进入光纤接收机51。光纤接收机的输出驱动一个偏正交相移键控(OQPSK)卫星调制器50。然后该信号被上行变换,放大和发送到卫星,如下面具体描述的那样。
在发射机50中接收从光纤发射机49至光纤接收机51的信号。来自光纤接收机51的信号通过故障保护继电器52—1进入OQPSK的激励器53—1。OQPSK的激励器53—1的数字信号进入分离器57—1,并且通过故障保护继电器52—2。之后,该信号通过上行变换器58—1。上行变换器58—1的信号通过开关56—1进入高功率放大器59—1,并且再通过开关电路56—2,然后发射。该发射最好经过卫星完成。该传输也可以经过同轴电缆或光缆实现。
冗余控制逻辑55控制发射机50,以便万一有故障时就启动冗余电路。特别是,冗余控制逻辑55控制继电器52—1和52—2以及开关56—1和56—2,以便转换到冗余的激励器53—2和分离器57—2,冗余的上行变换器58—2和高功率放大器59—2 。
参见图3,它描述编码器20—1的详细方框图。CD唱机10的输出被输入到复用器31。最好是把16个CD唱机10—1至10—16的输出送入复用器31,在那里它们的信号进行组合,并以两个频道输出给速率同步器33—1和33—2。然后,速率同步的信号输入至混合器与信号压缩器35。混合器与信号压缩器35最好使用在美国专利4,922,537号中所描述的数据压缩形式,引用该专利供参考。混合器与数据压缩器35由主控制器30—1来的输入信号控制,该主控制器还输入相应于数字音频信号的节目数据信号。数字音频信号被压缩,节目数据信号被混合,然后,混合的信号输入到帧同步检测器和输出格式化器37。电路37也可以包括加密该混合的和压缩的信号的电路,如使用数据加密标准(DES)或使用本领域公知的其它类似的加密技术。电路37可以包括纠错编码,例如使用汉明编码,BCH编码,或本领域普通技术人员公知的其它纠错/编码方法。汉明编码方法公开在由F.Mazda编辑的“电子工程师参考手册”(Electronic EngineersReference Book)第32/10页,引用在此供参考。
音频数据以每秒44.1千样值的速率被同步进入和输出电路33—1、33—2、35和37。混合压缩和加密的信号在申请人的优选实施例中是以1.12896Mb/s的速率由电路37输出。
参见图4,混合,压缩和加密的信号在C波段经过卫星的接收天线接收,并在低噪声信息组变换器(block converter)63中与其它的卫星分配信号一起放大和分组变换。该信号在L波段以950至1450MHz输出并输入给分离器65。在那里,音频信号输入给OQPSK接收机67。接收机67调解OQPSK信息并提供含有优选的30个卫星分配频道的34Mb/s的信号流。34Mb/s信号被接收机37以34MHz的时钟速率输出给多路分解器70。多路分解器70最好是一个1∶6的多路分解器,它把该信号数据流分解到6个频道,每个频道含有5.6Mb/s的数字音频和节目数据。这6个频道的每个频道包含5个站。
该信号以11MHz被同步送入调制器75—1至75—6。调制器75—1至75—6的每一个是一个9状态正交部分响应(9—QPR)调制器,它能处理5个站并且各自占据3MHz带宽。本领域普通技术人员知道,也可以使用相移键控调制或本领域公知的更多或更少状态的其它调制方法。
来自调制器75—1至75—6的已调信号在射频组合器80中与来自其它电缆调制器77的其它调制的信号进行组合。调制器75—1至75—6数字地滤波这数据。正交部分响应(QPR)调制并变换该数据为所选择的输出频率,以便与本电缆电视系统中的其它调制的频道77组合。五个立体声对的每个数据块占据3MHz带宽,并且能够在本电缆电视系统的6MHz视频信道的一半上传送。由于本系统使用一个公共的6MHz视频信道,所以不需要改变目前的CATV分配系统设备。
来自射频组合器80的组合信号经一个同轴电缆或光纤分配系统分配给一个用户家庭。定向耦合器85把大多数信号引导到视频机顶终端87 。信号的样值以10分贝的损耗从定向耦合器85送至数字音乐调谐器100 。调谐器100由一个简单的遥控201或者由一个音乐信息显示遥控200进行控制。另外,调谐器100输出左和右模拟音频信号,而且也可以输出一个任意数字信号输出。
参见图5,它示出了一个数字音乐调谐器100的方框图。数字音频和节目数据信号从定向耦合器85输入到机顶终端调谐器110。这个调谐器最好包含锁相环电路。调谐器110来的信号在被解调器125解调之前由放大器115放大,并由锯齿滤波器(Sawfilter)120滤波。调谐器110把所选的射频信道转变为解调中频。解调器125的输出进行QPR解调而产生包括五对立体声数字音频数据的5.6Mb/s的数据流给应用专用集成电路(ASIC)140。解调器125还提供一个自动增益控制信号130给调谐器110以保持恒定的信号电平。另外,解调器125提供数据给时钟恢复锁相环PLL135。数据时钟PPL135包括一个定时用的33.8MHz晶体137。
传送给ASIC140的这个定时信号将参照图6进行更详细的讨论。ASIC140提供数字音频输出给接口170。接口170使用Sony—Philips的数字接口格式(SPDIF)。类似地,该数字音频信号从ASIC140输入给数字至音频变换器160。数字至音频变换器160来的左和右模拟音频信号经滤波器165—1和165—2滤波并且输入至旁路170。旁路170允许附加的音频部件(如一个CD唱机或走带机构)可转换地与数字音频调谐器100连接。
微处理器150控制调谐器110的锁相环,ASIC140,数字至模拟变换器160和旁路170。ASIC140来的节目数据信号送给微处理器150,它被存入该处理器内部的存储器,并且可以在前面板接口180上显示或由遥控发射机190发送。遥控接收机195可以经过微处理器150选择特定的节目数据信息或音频信道。
电源175可以给该系统提供正五伏的数字和模拟电源,以及一个负五伏的电源。正12伏和正30伏电源信号也可由电源175提供。另外,调谐器100最好有输入装置,如按钮或拔动开关,在它的框架的外部(未示出)。这些输入装置可允许选择信道、台、节目数据的显示,以及包含在节目数据信号中的特殊信息组的显示。本领域普通技术人员还可以提供附加的选择或输入。
参见图6,它提供了ASIC140的更详细方框图。解调器125来的信号输入到解调器支持电路141,它含有在信号解调中需要的逻辑电路(如触发器)。然后,解调器支持电路141来的信号输入给多路分解器143,它分解该5.6Mb/S的数据流以便选择五对立体声数字音频信号中的一对。然后这个信号送入解密电路145。然后,解密的信号又在信号分离器148中分离,节目数据送到微处理器入/出电路149,而音频数据被发送并在电路147中译码。译码器147使用美国专利4,922,537所描述的数据去压缩技术,引用在此供参考。
微处理器入/出,地址和控制电路149与微处理器150接口。ASIC中的所有电路由时钟146驱动。存储器144存储数据的比特,以支持分别发生在电路143、145和147中的多路分解,解密和译码功能。该存储器可以是非易失型的,例如EPROM或类似的ROM存储器或者可以是由电池171支持的易失型RAM存储器,最好电池是锂型电池。这样的电池175可以防止存储器144存储数据的丢失。
参见图7,它示出了远程音乐信息显示单元200的方框图。接收机201从遥控发射机190接收节目数据信号。最好使用红外发射机和接收机190、195、201和205。但是,如本领域普通技术人员能知道的,也可以使用射频,超声、导线、光缆或其它装置。然后收到的信号输入到处理器203,它处理并发送该节目数据信号给显示器209,以便传递相应于目前播放的音频轨迹的节目数据给用户。显示器209可以是液晶显示器,发光二极管,盲文阅读器,语音合成器或阴极射线管或者本领域普通技术人员可能知道的任何其它通信设备。听觉的或触觉的通信装置,如愿意,使用远程单元,可以允许传递节目数据信号到失去能力的用户。
输入装置,如所示的键盘207,可以接收用户来的节目数据选择命令或或音频轨迹命令,这些命令发送到处理器203。键盘207还可以包括允许用户控制音量,功率,频道选择,台选择,显示或本领域普通技术人员知道的其它适合用户的命令的装置。处理器203然后变换并发射该用户命令信号给发射机205,该命令由遥控接收机195接收。接收机195接收的信号输入到微处理器150,适当的信号从那里发送给ASIC140和调谐器110,以便得到用户需要的音频轨迹,音频信道或节目信息。
中继器可以在住所到处放置以延伸显示/控制单元的范围。另外,处理器203可以包括用于存储各种信息特别是节目信息的存储器。
在一个替代的实施例中,远程显示单元仅能显示表示该节目数据信号的码号,因此,用户可以参阅在印刷材料中完整说明目前播放音频轨迹的编号。该印刷材料可以是出版物,它随各台节目的变化每月或每周循环一次。这样的系统可以允许远程单元用一个较小的显示器,因此,对用户来说费用更少。这样的印刷物还能让用户确定在各频道上正在播放什么节目。
另外,根据用户的请求,远程显示单元或调谐器100能够显示相应于不在该用户目前收听/观看的频道上发送的数据的节目数据。用这种方法,用户可以在收听目前播放的频道的时侯,扫描在其它频道正在广播什么节目。
优选的三十个立体声音频台按下述方式复用。五个台一组被格式化为一个数据帧。六个这样的帧逐比特地交替(interleaved),以便经过卫星传送。包含五个台的每个这样的帧都有一个标题(header)。前端多路分解器70使用这个标题解除卫星接收数据的交替,使成为各有五个台的六个帧。该标题在ASIC140中还用于帧同步。第二标题包含用户控制事务数据。这个第二标题最好合有如前面关于计费系统47描述的信道和用户事务数据。该标题含有用于误码检测的附加比特。
紧接着标题,发送与节目数据有关的压缩音频数据。如前面参照美国专利4,922,573号所描述的,对于九样值的每个信息组,每台的音频数据含有一个七比特的“K因数”和一个三比特的“指数”(exponent)。在每帧中每台含有五个这样的K因素和指数信息组。
在该帧中,五个台的音频和节目数据逐比特地交替。也就是,发送第一台的第一比特,接着第二台的第一比特,以此类推,直至各台的第一比特发送完。然后发送各台的第二比特,以此类推。在九样值的每个信息组中的最后音频数据比特发送完之后,以相同的方式传播节目数据比特。因此,每台的节目数据在与它相关台的帧中进行复用,以便当该帧被多路分解或重新安排时,那个台的节目信息被保持在它的台中。节目信息与音频数据复用的优点是可以容易地处理该组合信号,而不必担心音频数据与它们的各节目信息抢夺信道。纠错和检测比特也与音频数据和节目数据一起传送。
在同一信息组中,两个节目数据比特与音频数据的每九个压缩样值(100比特)一起传送。这有效地提供了一个传送节目数据信息的约9800波特的数据信道。该信息以ASCII表示法发送,但也可以简单地以其它格式发送,如本领域普通技术人员显而易见的EBCDIC。在本实施例中优选传送的节目信息和各字段的容量如下。其它信息如对于所选电台音乐类型的音乐分类、特别事件的通知、或本领域普通技术人员知道的其它信息也可以传送。
