在分段层级上显示诸如电视节目内容的方法和系统。包括将内容分割成至少两段,显示该至少两段中至少一段的代表内容,以及指明该至少两段中的至少一段如何与内容关联。术语“内容”涉及任何类型的可以广播、被用户存储或者其它传输给用户的节目或信息。
Description
参照相关申请
本申请是一个美国临时和母案申请的非临时申请,该美国临时和母案申请为2000年7月28日提交的,美国序列号为60/221,401,申请名为“在子节目级电视节目的显示与重放”,发明人为:GeorgeMarmaropoulos和John Zimmerman,该申请整体在此引为参考。发明背景
本发明总体上涉及关于用户化电视观看过程的用户互动模式。
通过提供大量的数字内容,数字电视和数字信息已经而且将要继续改变家庭娱乐。可得到的频道的数量和内容的种类将变得大到任何观众都不可能利用常规的频道冲浪方式浏览这些内容。电子节目指南(EPG),例如在此引为参考的美国专利第4,706,121和第5,353,121号中所描述的那些,提供了节目单信息处理系统,为观众提供一种便利的方法,它根据观众提供的选择标准来选择节目。但是,即使是EPG,尽管它们已经发展到目前的水平,也不足以为很快将可以获得的大量信息提供个性化层次的选择。
各种各样的设备和系统,如个人TV记录器和代理技术提供了一定程度的个人化选择。这些系统利用EPG和用户偏爱工作在元数据(meta-data)级上。为简化观看偏爱节目的过程,这样的设备通常具有可存储几个小时视频内容的硬盘。但是,允许用户直观地搜索并找到他们愿意看或听的特定内容的新的互动模式正变得越来越必要。
现在,用户根据单个的、不可分割的节目来想象内容。因此,用户只能在节目级上选择看和听的内容。
发明概述
根据本发明的一个方面,在分段层级上显示内容的方法包括几个步骤。一个步骤是将该内容分割为至少两段。另一个步骤是显示上述至少两段中至少一段的代表内容。附加步骤指明所述至少两段中的至少一段如何与内容关联。
术语“内容”涉及可以广播、由用户存储,或传输给用户的任何类型的节目或信息。
本发明的一些实施例中,分割步骤还包括基于采样帧内的象素色彩分析、对话分析、目标识别技术、文字内容说明、封闭字幕、语言到文本、MPEG 7、或音频分析等的分割。分割可以根据任何已知的方法进行。
在本发明的另外一些实施例中,指示步骤可以包括用符号指示每一段的长度或一段长度相对于包含该段的内容的长度。指示步骤还可以包括指示在包含该段的内容中分段的时间位置。
在其它一些实施例中,指示步骤可以包括生成图像或文本的符号。用户能够用这些符号搜索内容。
在另一实施例中,用户可以选择分段的代表内容,以全部或部分的格式显示(即播放)该分段。
在另一实施例中,所述方法包括将分段存入存储介质。用户也可以存储和显示多于一个的分段。
在本发明的另一方面,在分段层级上显示内容的系统包括至少一个内容源、分割内容的装置、以及用于显示分段内容中至少一个代表内容的显示装置。
在一些实施例中,上述显示装置为电视机或监视器。内容至少是一个电视节目源或线性媒体源。另外,电视节目或流式媒体源是卫星源、陆基源或广播源。
在其它实施例中,分割内容的装置工作在内容前端或用户位置上,或者工作在内容前端和用户位置两者上。
在其它实施例中,分割内容的装置根据用户个人的观看习惯自动分割内容。另外,显示装置显示上述至少两段中的至少一段。
在本发明的另一方面,存储在处理器可读介质上用于在分段层级上显示内容的程序包括执行步骤的部分。该程序段包括把内容分割成至少两段的部分、显示所述至少两段中至少一段的部分、以及指示所述至少两段中的至少一段如何与内容关联的部分。
本发明有几个优点:只为举例而言,系统、方法和程序段都能够分割内容并显示分割后的内容。用户可以只选择他们希望观看的分段,也可以在大量内容中搜索特定的分段。随着频道数目和信息量的持续增加,它可使观看电视较为容易且较为人性化。此外,大量信息可以快速简便地组织和观看,而不需要过多地扫描。这些和其它优点在下面参照实施例加以阐述。

实施例详述
建议的方法、系统和程序为电视观众提供在子节目级(以下称为“分段层级”)上选择内容的能力。
图1表示建议的包含分段层级代表内容的用户界面的优选实施例。用户开始从用户界面100上的目录菜单10中选择。在此用户可以在目录范围内搜索内容。图1中,用户利用常规的输入装置如遥控器或键盘选择谈话节目。这样,会显示出适合所选的谈话节目目录的内容(即,由图标表示的电视节目)。适合该目录内容的每一部分都可以选定。图1中,用户利用常规的输入装置如遥控器或键盘选择图标11。图标表示不同的部分内容(即,不同的节目)。
图标11对应于电视节目“The Late Show with DavidLetterman”,以下称“The Late Show”。该节目中包括有嘉宾访谈、音乐家演奏、喜剧表演等各种分段。
已知的在分段层级上分割内容显示的方法有几种。一种方法通过细读与内容相关的封闭字幕来标识分段开始和结束的提示,从而将内容分解为分段。例如,标识分段开始的提示可以是词语“今晚我们下一位嘉宾是
”。标识分段结束的提示可以是持续的掌声伴随词语“谢谢
”。另一种方法从节目的内在结构上标识分段。这是通过例如识别在其中音乐播放中的持续部分,从而实现谈话节目中对音乐演奏的标识。提示应当在音乐开始和结束的时刻。另一种方法是识别与分段相关的声音,例如在一场足球1/4决赛开始和结束时的吹哨子,或者掌声达到某一音量阈值的部分(即体育比赛中的精彩表现部分)。可以有许多其它的分割内容的方法,它们可以用于本发明。
图1中选定图标11时,分段显示区域12显示分段代表内容13-17。分段代表内容13-17代表The Late Show中的各分段。例如,分段代表内容13对应于The Late Show中嘉宾是Dolly Parton的分段。分段代表内容14对应于The Late Show中Drew Carey临场的分段。如果用户希望观看The Late Show中的一个或多个分段,他可以选择相应的分段代表内容。一旦选定,分段就可以显示或存储。例如,假设用户从分段显示区域12中选择分段代表内容13,那么用户就可以观看该分段,编辑一串所选的分段,并作为可编辑的蒙太奇整体进行观看,或存储该分段以便以后观看。
分段代表内容的面积与分段的时间长度成比例。例如,图1中,简单观察分段显示区域12会发现分段代表内容13和14比分段代表内容15和16长。另外,用户可以快速方便地将分段代表内容的长度和全部内容(即一个节目)的长度相比较。例如,用户可以估计分段代表内容13大约为分段显示区域12的长度的1/5。因此,用户可以判定,既然The Late Show为1小时长,那么对应于分段代表内容13的分段是1小时的1/5或12分钟长。另一种情况,当用户加亮分段代表内容时,他可以获得分段的长度和分段相对于全部内容的长度。
图2表示用户界面101,在其上面分段代表内容为用户提供关于内容部分各分段的详细信息。显示区域12仍然包含由图标如图标21指示的分段代表内容13-17。当用户加亮分段代表内容时可以获得信息,诸如关于名人、构成分段的提示和主题等的信息。图2中,当用户加亮对应Dolly Parton的分段代表内容13时,出现信息20,帮助用户决定是否存储或观看加亮的分段。
如上所述的显示分段代表内容之所以是有用还有一个原因。通常,内容部分较多强调其中包含的某些分段。例如,新闻节目会重点强调“今日要闻”分段。而且,“今日要闻”通常在内容部分中比较靠前。根据分段与全部内容的关系,在分段层级上显示的内容使用户能够了解分段相对于全部内容的位置,以及该分段有多重要。
图3示明允许用户按分段搜索内容的用户界面。根据用户界面102,用户搜索了关于经济的内容部分,即从图1的目录菜单10中搜索了经济。根据用户的搜索找到由图标31-33表示的内容部分。然后,用户可以在分段层级上进一步搜索内容部分31-33。用户通过从搜索引擎36选择特定的分段37来执行该分段层级搜索。图3中,用户只希望在关于经济的内容部分内找到关于诺基亚(Nokia)的分段。如显示区域34和35所示,找到了分段代表内容38和39。用户会发现在图标33所表示的内容部分中,没有包含所期望的分段。此外,用户会看到,对应于图标32的内容部分包括一个关于诺基亚的分段(即分段代表内容39),该分段显得比图标31对应的诺基亚的内容部分更详细。用户可希望观看或存储在搜索中找到的两个分段,或者只观看或存储较短的分段(即,对应于分段代表内容38),或者只观看或存储较长的分段(即,对应于分段代表内容39)。
图4示明在分段层级上显示内容的系统。显示屏401显示用户界面101。分段代表内容和菜单可以用光标(未示出)进行选择、编辑和其它操纵。可以利用常规输入设备如遥控器47或本技术领域已知的任意其它通用的输入设备使光标向左、向右、向上和向下移动。
一旦用户选定内容部分的一个目录,微处理器45就扫描内容源44以搜索选定的内容部分。然后,微处理器45根据用户输入对选定的内容部分进行分割。这种情况会出现在比如用户选择一个代表内容部分的图标时。然后,微处理器45将如上所述分割节目,并将各段显示为分段代表内容。另一种情况,微处理器45可以扫描内容源44,并把节目分割到一个以上的目录中。
当用户选择分段代表内容时,微处理器45可以引导显示器401显示该分段。微处理器45也可以将选定的分段存入存储介质46。微处理器45还可以根据用户个人的观看习惯自动分割分段。
分段层级显示更一般地涉及所有形式的流式媒体,例如无线电,以及从因特网馈送来的流。例如,无线电设备的用户接口(例如数字电缆无线电馈送(digital cable radio feed))。该无线电内容部分可以被分割、搜索和显示,供用户选择。
图5中的方框图描述存储在处理器可读介质上的程序用于显示分段内容。该程序在步骤500询问用户是否选定了一个内容目录。如果没有选定,则程序引导微处理器45在步骤502生成目录菜单。一旦生成,则程序引导微处理器45在步骤503和504分别请求和接受输入。如果用户在步骤500选定了一个目录,或如果在步骤503接受了输入,则程序引导微处理器45根据在步骤501选定的目录来搜索和/或过滤内容。
一旦根据选定的目录搜索和/或过滤了内容,程序询问用户是否希望在目录结果内搜索分段。这发生在步骤505。如果用户不希望在选定的目录内搜索分段,程序就询问是否选定了代表内容部分的图标。这发生在步骤506。如果没有选定,程序在步骤507等待选择图标。当用户选择了图标时,该图标代表的内容部分就在步骤508被分割。
如果用户希望在选定目录内搜索分段,程序引导微处理器45在步骤509分割在该目录内的全部内容部分。在步骤510,程序询问用户是否选定了分段目录。如果没有,程序引导微处理器45在步骤511生成一个分段目录菜单。一旦生成,程序引导微处理器45在步骤512和513分别请求和接受输入。如果用户在步骤510选定了分段目录,或者在步骤513接受输入后,程序引导微处理器45在步骤514根据选定的分段目录搜索和/或过滤分段。一旦图标代表的内容部分在步骤508被分割,或程序引导微处理器45在步骤514根据选定的分段目录搜索和/或过滤分段,程序就会引导显示屏401在步骤515把分段显示为分段代表内容。
前面的说明和实例是示范性的,而不是要限定下面的权利要求的范围。
