Description

将多源信息合并于电视系统中
发明背景
现有技术包含用于提供与电视时间表指南信息有关的几种方案。这种信息常被用于提供可收到的频道以及它们的有关电视节目的屏上(on screen)的框格状。通常，Y轴上显示可收到的频道的目录，而X轴由时隙(time slots)占据。这些列在表上的频道可以在电视机上顺序地显示中或以任一最佳的预定的次序出现。第5,353,121号美国专利是这类系统中的代表，并在工业中取得了广泛的成果。因此通过引用，把第5,353,121号美国专利包括了进来。
当前可以得到许多不同的用于提供电视时间表指南需要的信息的传送方案。例如，直播电视系统(DBS)可以通过一个卫星抛物面天线和一个高置的接收机一起提供电视节目和电视节目是间表信息。DBS系统可以从比如Hughes和Primestar买到。另外，用传统的卫星抛物面天线、同轴电缆、电话线路、光缆、天线，等等，对电视节目和/或节目时间表信息进行散布。
如果一个用户定购DBS，则通常提供具有屏上显示发生器的一个单独的IRD(集成接收译码器)单元(box)。IRD单元通常最基本地包含接收机和调谐器。DBS用户接收到由DBS服务提供者提供/控制的通向可能数百个电视频道和节目指南的入口。不幸的是DBS系统通常不接收本地的电视广播网或本地的独立频道。为了提供这些缺少的本地频道，一些DBS接收机可以自动地在DBS卫星输入和本地输入之间进行切换。这通过将IRD单元置于电视机(或连接到电视机的录像机(VCR)和本地线路(本地电缆(即，有线电视，译者注)或本地天线)之间来完成。当用户选择本地频道时，IRD单元自动地将DBS从服务中消除而成为本地输入的旁路(bypass)。用户既可以手动也可以用遥控挑选一个本地频道。由于黄金时间的观看大部分是在本地的广播电视网上，故通向本地所有频道的入口是非常重要的。
可是，如果用户正从电缆和本地天线源接收电视频道，则情况不同。如果用户的电视机具有多个电视输入端口，则这两个源可以容易地接到两个输入端口。只要源的数量不大于电视机输入端口的数量，这个解决办法很奏效。
如果用户的电视机不具备多个输入端口，则可以利用连接到多个源和电视机输入的手动开关箱。这个解决办法迫使用户根据想要哪一个频道而在一个源和另一个源之间，手动切换。例如，如果用户想看从本地天线可以收到的本地新闻，而开关正置于电缆，则用户必需手动地从电缆切换到本地天线。在一个充满了遥控和自动控制的社会中，对许多消费者来说这种解决办法是难以接受的。而且，当频道源的数目增加时，在频道之间手动切换将变得更加复杂。
尽管IRD单元、多个电视机输入端口、手动切换装置，等等为上述问题提供了非自动的而且有时是部分的解决办法，但仍要一个更通用的技术。
发明摘要
在较佳实施例中，本发明导致对输入信号和节目信息进行协调，特别，本发明导致：(1)对从多个源接收到的电视时间表指南信息进行协调，(2)自动地切换到想要的信号源，和(3)调谐到想要的的电视节目。因此，本发明提供了一种调谐方案，这种方案对电视时间表指南信息进行协调。此信息可以从许多的源接收到。这些源包含输入电缆线路(比如在同轴电缆上)、卫星广播、专用电话线路(比如扭绞线对)，和任何其它能够传送信号的媒体。
本发明提供了一种将频道指南的信息合并到电视系统中的方法。这种方法包含频道指南的信息的接收和存储。频道指南的信息是从多个电视信号源接收到的。接收到此频道指南信息之后，系统将它混合并按想要的的次序进行分类。最后，产生了此频道指南信息的显示，并随后按照想要的次序显示在电视机上。
在阅读了下面结合附图对本发明详细的描述之后，对于熟悉本领域的人来说，这些和其它的一些优点将是显而易见的。

实施例说明
本发明提供了一种协调电视节目和电视时间表指南信息的调谐时间表。电视时间表指南信息可以从许多源接收到。如上所述，这些源包含输入电缆线路(比如在同轴电缆上)、卫星广播、专用电话线路(比如扭绞线对)，和任何其它的能够传送信号的媒体。在较佳实施例中，电视频道广播是从至少两个分开的信号源如(1)电缆和卫星抛物面天线，或(2)两个不同的卫星，或(3)本地电缆和DBS源接收到的。时间表信息上设有将时间表信息识别为来自一特别源的标识符。对时间表信息进行分类，并以经过编排的形式显示给用户。
当一个用户选出了在所显示的指南中一个所显示频道的节目或者频道时，这个系统读出和那个节目或者频道相关的标识符。在较佳实施例中，系统随后执行一个将电视机一的输入(RF或视频)切换到源装置的自动切换/调谐过程。源装置包含DBS、电缆箱、电视调谐器，等等。然后，这个系统为观看想要的节目调谐到想要的频道。另外，当想要无人看管的VCR广播节目时，可以利用源标识符以在各种设备间自动切换。而且，当从多个卫星源接收到节目信息并选出想要的频道时，在一个实施例中，本发明可以自动地移动用户的卫星抛物面天线，以使用户从相关的源接收到想要的节目。本发明随后调谐到正确的频道。
在制作合并的电视指南中，制作了识别在多个信号源上可以获得的频道并识别其源的频道图(channel map)。例如，在实行DBS/本地频道的情况下，制作出合并本地电缆和DBS频道的频道图。本地频道和BDS频道加有标识符。当用户/消费者从指南上选择非DBS频道时，用于卫星的集成接收译码器装置(IRD单元)对IRD进行切换，以将本地电缆连接到接收机。随后，这个系统将电视调谐器或者其它的调谐装置调谐到想要的频道。如果后来选择了一个DBS频道，则这个系统对IRD进行切换，以将卫星接收机/译码器连接到接收机。然后，这个系统将DBS调谐器调谐到所选出的DBS频道。比如在电缆和天线的输入的情况中，这个系统切换到正确的视频输入，然后将电视调谐器调谐到想要的频道以接收选出的源。这样，提供了到多源电视时间表指南信息的自动入口。
在本发明的另一个实施例中，用户可以利用系统在目的地装置之间进行切换。比如，可以在计算机屏幕上显示或者在立体声系统中播放从多个源中的一个源接收到的信息/节目。另外，可以几个目的装置相互连在一起使用。例如，可以在计算机监视器或者电视机显示器上显示FM无线电台的节目表，并且然后可以在一个录音机上录下从那个节目表上选出来的歌曲。而且，可以利用系统将电视机音频的输出连接到立体声系统。这样，本发明就不局限于电视机系统了。
图1a以简化的形式说明了多源电视时间表指南系统10，其中多个源直接连接到电视机22。如图所示，多源电视节目和电视时间表指南系统10在协调器20的控制下进行工作。将来自电缆单元26和IDR单元28的输入提供给电视机22和VCR24。还可以将其它的输入也提供给电视机22和/或VCR24。一个观看者用遥控器32对电视机进行调谐，并进行其它的操作。在这个实施例中，通过电缆单元提供电缆，通过IRD单元提供DBS。除了电缆单元26，IRD单元28，和其它输入30之外可以将电视机22上的天线，用作额外的信号源。在一个典型的实施例中，天线34和电缆单元26是“本地”源。其它输入30可以包含多个卫星源。当出现多个卫星源时，协调器20通过自动地移动用户的卫星抛物面天线或者在若干卫星抛物面天线之间切换，来在可以获得的卫星源之间切换。为了自动地移动卫星抛物面天线，在IRD单元28中的存储器相应于卫星源对DBS卫星抛物面天线的位置进行追踪，卫星源通过DBS卫星抛物面天线可得到。随后，IRD单元28自动地确定DBS卫星抛物面天线的位置，从而通过IRD单元接收想要的卫星源。
协调器20包含处理器(CPU)36和存储器(RAM)38。将协调器连接到红外线(IR)发射器40并对它(们)进行控制。IR接收器39连接到协调器20，并接收来自遥控器的输入。IR发射器40可以由比如总线接口(bus interface)或RF发射机代替。IR发射器40控制一个或者更多个IRD单元28、电视机22、VCR24、电缆单元26，和其它输入30。这样，IR发射器40通过模拟电视机22、VCR24、电缆单元26，和/或其它装置的遥控信号，用作遥控装置。因为协调器20有模拟遥控器的能力，因此可把协调器20放置在电缆单元26、VCR24、电视机22，独立装置20，或卫星接收器24中。
遥控器32是控制协调器20的手持式遥控器。在较佳实施例中，给遥控器32设置一个通过IR接收器39控制协调器的IR发射器。可以用图1a中未示出的其它遥控器以手动控制电视机22、VCR24、电缆单元26，IRD单元28，和其它输入30。虽然如此，在一个较佳实施例中，由协调器20完成系统所有必需的控制功能。在一个较佳实施例中，遥控器32和协调器20以及发射器40一起工作，以控制图1a中的各种装置。例如，当用户调整遥控器32上的音量控制时，协调器20通过IR发射器40发射信号，以调整电视机22的音量。
在用户实施例中，IRD单元28通过卫星抛物面天线29接收电视节目和其它信息。IRD单元28随后将节目时间表信息提供给系统。通过DBS服务的供应者或者签约的公司，将时间表信息加至发射的信号。DBS服务供应者的例子包含Direct TV和USSB。这个节目时间表的信息(或指南)还可包含一个频道图，该图包含可在特定的源上得到的频道信息。把和DBS指南相关的信息存或卸载在IRD单元接收器的RAM42中。类似地，可以通过电缆单元26、其它输入30、天线34，和/或通过任一其它的传送媒体(比如专用扭绞线对电话线路)接收节目指南信息。在由服务的供应者传送的信号中，对这些源中的每个源也可能设置电视时间表数据。
协调器20找出在系统10中可以得到的节目指南信息并对其分类。为了接收想要的电视指南信息，把协调器20连接到此信息的源。比如，如果通过专用的扭绞线对电话线路提供频道图的信息，则该电话线路是通到协调器20的输入端43。可以从任一买得到的媒体提供指南信息，并可以应用于所有的或者一些可得到的源。在较佳实施例中，通过垂直消隐期间在可得到的电视频道上提供电视指南信息。在图1a中，把源装置和协调器20连接到电视机22。这样，协调器20通过电话线路43接收节目指南信息，而且电视机22从多个源接收电视节目。另外，电视机22从协调器20接收节目指南信息。
在本发明的另一个实施例中，协调器20直接接收所有的源装置输入。图1b是一个多源电视节目和电视时间表指南系统的方框图，其中把多个源直接连接到协调器。在这个实施例中，协调器20在多个源26、28和30之间切换，然后将信息从想要的信号源输出到电视机22或者另一个目的装置。这种结构允许至电视机机22的单个输入。协调器20通过线44或者经VCR24通过线45和46将节目指南信息和电视节目输入到电视机22。用于本发明的其它可能的目的装置是计算机监视器、录音机、传真机、打印机、存储器，等等。
在本发明的再一个实施例中，DBS(经IRD单元28)和电缆(经电缆单元26)是串联到电视机22的信号源装置。图1c是以DBS和电缆作为源装置的一种电视节目和电视时间指南系统的方框图。在这种结构下，把协调器放置在IRD单元47中，而不需要IR发射器。IRD单元47直接或者通过VCR24输入到电视机22。当DBS通过IRD单元47中的协调器从服务中被去除时，电缆单元26输入到电视机22。
图1d是一种电视节目和电视指南系统的方框图，该系统在同一在IRD单元中有DBS、协调器和电视调谐器。在这个另外的实施例中，没有出现电缆源，并且DBS、协调器和电视调谐器都被放置在IRD单元48中。这样，不需要发射器。协调器在DBS和其它在线49上可得到的源之间进行切换。在协调器进行了切换并且调谐到需要的频道后，(如下所述)该频道在电视显示器23上显示或者由VCR24录制。在图1a-1d中的VCR是可以选择的。另外，DBS接收器和调整器可以放置在电视机或者VCR中。
可以将各种格式应用于电视时间表信息。例如，可以接收包含标题部分和信息部分的数据包，并用其它更复杂的数据包格式进行分类(sort)。在较佳实施例中，协调器20从可得到的源或者数据输入线中获取电视时间表信息，并对其进行分类/混合。例如，协调器20可以通过电视频道中的垂直消隐期间或者通过DBS的差转机(fransponder)接收节目时间表信息。
为了对得到的时间表信息进行分类/混合，协调器20首先制作出一个结构框架，然后将接收到的数据存储在那个结构框架中。这个结构框架包含几个用于经过组织的数据存储的层次(level)。当协调器20准备好框架的层次后，利用指针将数据保存在这个结构的适当的层次中。
在另一种结构中，节目时间表信息的分类/混合在分开的场所中进行，然后提供给系统10，比如，在一个卫星频道上。这样，便以一种随时可以立即显示的格式接收已经进行了混合、分类、组织等等的节目时间表信息。在后面这种情况下，因为只有被观看的屏幕/框格需要保存，在协调器里只需要很少的存储单元。比如，在后面这种的情况下，如果用户希望观看长达四小时的框格指南，在RAM38内只需要保存四小时的信息。通过其它的媒体或者在电视频道上也可以提供这种随时立即显示(ready-for-immediate-display)格式。
图2是已经从电视指南信息中经过组合的时间表框格指南的屏上显示的例子。本发明的框格指南还指和包含主题指南、频道指南，和其它显示节目信息的指南。在较佳实施例中，当协调器20对所有可得到的节目指南信息进行了收集和分类后，协调器20产生出图2所示的框格指南，以在电视机22上显示。也可以在IRD单元，卫星接收机，电视机、VCR、中(central office location)，等等中制作出这个框格指南。由标号50概略地指出的这个框格指南提供了组所有的频道或者经挑选的频道52，以及在某一时刻56在那些频道上可以得到的节目54的描述。比如，从1：00p.m.到2：00p.m.频道2(58)上有节目BATMAN(60)，而从2：00p.m.到2：30p.m.有节目SOAP(62)。可以使用主题、或频道、或任选(random)等等的列表代替图2所示的框格指南。
如果使用框格指南，可以这样安排这且频道52，从而(1)频道按数字和/或字母为序，或(2)频道按与它们特定的源相关的次序为序，或(3)频道按用户编程的混合次序为序，或(4)频道按任何其它的安排为序。当使用多个源接收电视频道时，有时会发生频道的重叠。比如，电缆和DBS都传送ABC网，但电缆电视可能在频道6上有ABC，而DBS可能在频道7上有ABC。由于具有删除和创设显示在框格指南50中的频道的能力，用户可以决定是要ABC频道之一，还是要两个ABC频道，或者是两个ABS频道都不要。通过遥控器32将用户的选择输入到协调器20中。在另一个实施例中，协调器20可以自动地提示重复的网的名称，并删除掉重复名称之一。另外，协调器20能够自动地根据用户的习惯对频道进行排列。如果用户选择了这种用于自动对频道进行排列的模式，使用一种根据用户习惯的算法决定频道的次序52。因此，对频道52的排列可以得到任何想要的安排。
在较佳实施例中，用户通过按遥控器32上的指南按钮显示框格指南。协调器20通过自动地转换到播送框格指南50的频道或装置，或者叠加当前广播中的框格指南来对最初的按指南按钮作出响应。当用户处置框格指南50时，用户再按指南按钮(或者按退出按钮)，协调器20就：(1)自动地返回刚才用户观看的频道或者源，或者(2)去除叠加。下面将进一步描述协调器20用于自动调谐的技术。
为了探索从哪个信号源上可以得到哪个频道，每一个频道上都设有标识符。每个源标识符都可以被包含在频道指南信息中，或者信号源识别符可以根据频道指南信息的出处由系统来添加。因此，如果还未提供这些数据，协调器20将适当的标识符加在接收到的频道指南信息上。比如，如果通过IRD单元28接收到BATMAN(60)，则BATMAN(60)将具有一个源标识符以识别位于其频道58上的IRD单元28。在较佳实施例中，源标识符不显示给用户。如果需要，用户可以对协调器20编程以显示和这个频道相关的是哪个源。比如，来自电缆单元26的频道可以在框格指南50中标成红色，来自IRD单元28可得到的频道可以是绿色的；这样，如果需要，用户可以容易地识别和每个频道相关的是哪个源。
用户可以利用遥控器32对协调器20编程或是在框格指南50中的不同的频道、时间和节目间进行移动。而且，遥控器32可以用于选择某一频道或者节目：(1)用于显示和一特定的节目相关的附加信息，(2)用于调谐到一个特定的频道或者节目，或者(3)用于自动地录制一个特定的节目。遥控器32也可以用于调整电视机22或者其它装置的音量或其它特性。和特定的节目相关的附加信息可能包含对那个节目的简短描述。比如，可以提供包含在情景喜剧中的故事的梗概。为了显示这个附加信息，协调器20在RAM38中对想要的信息进行访问，或是切换到不同的数据输入，并在框格指南50中适当的位置中显示附加信息。在较佳实施例中，如此显示附加信息：(1)以叠加的方式，或(2)作为被选择节目的下拉窗口，或(3)在屏幕的顶部或者底部作为说明信息的窗口。
图3是一个自动调谐的例示过程的流程图。为了开始自动调谐，用户在步骤70选出了某个频道或者节目。可以通过比如移动光标到想要的节目并按“enter”’键，或者用遥控器32输入一个频道号码来作这个选择。然后，协调器20在步骤72读出源标识符，并确定当前至电视机22的输入是不是和源标识符相关的源(见步骤74)。如果当前至电视机22的输入源标识符相关的源相同的源，则在步骤84，协调器将那个特定源调谐到想要的频道。如果当前的源不是和源标识符相关的源，则系统将源切换到适当的源。比如，处理器36可以使IR发射器40发射信号，这个信号自当前源切换，启动或者切换到和源标识符相关的源。随后，想要的频道或节目作为输入信息到电视机22的源。然后，协调器20在步骤80确定是否启动了对于那个特定的源(该源与源标识符相关)的正确的电视频道或者输入。如果尚未启动正确的电视频道或输入，则将系统中适当的调谐器调谐到适当的频道。例如，在步骤82可以用IR发射器40将电视机调谐到想要的电视频道。或者，可以去除步骤80，而协调器20则总是调谐到或重调谐至想要的频道，藉此，确认电视机22是在正确的频道上。在和想要的源相关的正确的电视频道或输入启动之后(或是同时)，在步骤84，IR发射器40将那个源中的接收机调谐到想要的频道。随后，在电视机22上显示了想要的广播。如果通过协调器20将节目输入到电视机22和/或VCR24(见图1b)，则电视机和/或VCR不再需要调谐。因此，在这后一种结构中，不出现步骤80和82。
为了进一步阐明图3所示的这个过程，提供了下面的例子。在这个例子中，IRD单元28具有可得到的频道100-200，而且目前是至电视机22的输入源(见图1c)。在步骤70，一个用户选择了频道2(58)上的BATNAM(60)。在来自电缆单元26的一个频道上可以得到所选的节目。协调器20在步骤72读出和所选的节目相关的源标识符，并确定频道2来自电缆单元26。随后，协调器20在步骤74确定当前源是IRD单元28。因此，必需发生源的切换。如上所述，当DBS不再是所选的源时，IRD单元28允许电缆单元26通过一个在IRD单元28中的内部中继(电子的或机械的)将信号传送到电视机22。因此，协调器20在步骤78利用IR发射器40使DBS不工作或者和它断开联系。IRD单元28通过电视机22的频道3输入到电视机22。在现在的这种结构中，电缆单元26也通过电视机22的频道3连接的。然后，协调器20可对电视机22进行检查，以保证它是在频道3上，如从电缆单元26输入所要求的那样，(见步骤80)。由于电视机22已经在频道3上，对电视频道不作任何变化(见步骤84)。随后，协调器20在步骤84利用IR发射器40将电缆单元26调谐到想要的频道2。如上所述，步骤82和步骤84可以同时发生。随后把节目显示在电视机22上，而图3所示的过程完成了。在其它实施例中，将利用电视机调谐器在来自源的许多输入中进行选择，或是提供一种混合系统，其中把电调谐用于一些源，而把源调谐器用于其它源。
图4是自动的、无人看管的录制的例文过程的流程图。为了开始自动的、无人看管的录制工作，用户用遥控器32选出了要录制的电视节目。为了提供所选节目的自动录制，VCR24在适当的时刻自动“接通”(和启动VCR的录制特性一起)，然后当节目结束时自动“断开”。用于自动录制的调谐过程和所示的用于自动调谐的程序是一样的(见图3)，但把VCR而不是把电视机调谐到正确的频道。
如图4所示，在用户在步骤90选出一个节目后，协调器进行检查，以查看是否已过了那个节目开始时刻(见步骤92)。如果还没有过开始时刻，则协调器20在步骤94等待。当到了正确的时刻(节目开始的时刻)，VCR24“接通”(见步骤96)，而协调器20就象已经发生自动调谐那样地工作。因此，协调器20在步骤72读出和提供所选节目的频道相关的源标识符(见图3)。这个在用于自动录制的过程流程和用于调谐的过程流程之间的转换由B指出。在自动录制的调谐序列中，将VCR(而不是电视机)调谐到正确的频道(见步骤80和82)。当完成图3所示的过程流程后，如A所指出的，协调器20在图4的步骤100中利用IR发射器40启动VCR的录制特性。这使VCR24录制所选的节目。协调器20然后在步骤102进行检查，以查看当前是否与节目结束的时刻相符。如果节目没有结束，协调器20在步骤104等待。当当前时刻与节目结束的时刻相符，IR发射器40在步骤106结束录制节目，并将VCR“断开”。这个方案允许对连接到VCR24的任何源中可得到的任何节目进行无人看管的自动录制。
在本发明的另一个实施例中，把协调器20放置在IRC单元28中，并且协调器20控制DBS和电缆源所需要的切换和调谐而不需利用IR发射器。当用户/消费者从指南上选出非DBS频道时，协调器从用于卫星的集成接收译码器装置切换到电缆(如果源最初是DBS)，并继续将电视调谐器或者电视调谐器以及电缆单元到想要的频道。如果后来选择了DBS频道，则系统切换回集成接收译码器装置，并调谐到需要的DBS频道。这种结构允许不需IR发射器进行多源的协调。
在协调器20的协助下，用户不必手动地选择电视节目源或者手动地调谐到想要的频道或节目。而且，由于在系统10中可得到的自动接收、框格指南生成、切换和调谐，如果有来自终端用户或消费者的任何手动相互配合，那也极少。
虽然上面提供了本发明的完整和全部的揭示，但对熟悉本领域的人来说，显然可以作出各种修改和变化。
