Description

用于提供用户自适应的多级别提要流的方法
本发明涉及用于提供多媒体流的方法，具体涉及用于提供用户自适应的多级别提要流(要点)的方法，其能够提供反映用户偏好／非偏好的多媒体提要流。
近来，随着数字视频技术和图象或视频识别技术的发展，用户可以通过搜索或浏览整个流的特定段来容易地使用希望的信息。换句话说，通过再现视频流和容易地仅仅浏览视频流的希望部分或索引视频流的提要，用户已经能够有效地理解预定视频流的内容而无需察看整个视频流。
为此目的，已经进行了一种处理多媒体流的研究，以便在用户要求希望的多媒体流时描述具有整个多媒体流或多媒体流的段的基于内容的数据和搜索该基于内容的数据。基于内容的数据包括：关于节目的全部内容的信息，例如关于制片公司、导演、演员表的信息；和关于多媒体流中每个段的语义信息，例如关于整个多媒体流中对象或背景的出现／消失、事件的发生、和对象与事件之间的关系的信息。
当上述信息被存储在用于多媒体流的基于内容的数据区中时，用户通过取出该基于内容的数据可以选择性地搜索希望的流，或仅仅浏览多媒体流中的希望部分。
因此，如果存在一个用户请求，例如说：“仅显示其中有一个男演员出现在特写镜头中的场景”，那么采用一种根据基于内容的数据提供多媒体流的方法的装置将显示对应的段。这里，该基于内容的数据包含视听对象的出现，视听对象的状态，事件，背景，段信息。此外，段信息包含时间的开始和结束点，代表一个段的视听对象，一个段的文本描述，和一个段中显示的事件。
同时，在美国专利No．5，913，013中，通过使用一种设置暴力场景、裸露场景、男演员和／或女演员露出的部分的级别等等，以及设置段代码的方法来构建内容映象，并且用户能够容易地仅仅浏览希望的部分。
下面将对根据常规技术的提供多媒体流的方法进行详细说明。
图1表示根据常规技术的用于描述多媒体流的基于内容的数据的方法的例子，其中与段信息一起描述多个注释(注释1，注释2，…)。
此处，注释是指视听对象的出现，视听对象的状态，事件，背景，和段信息，Si(i=0，1，2，…)表示段。
但是，虽然上述基于内容的注释有助于用户容易地搜索希望的部分，但是该注释很难满足用户在很短时间内理解全部内容的需求。
为了解决上述问题，提出了一种用于在多级别段信息方案中描述多媒体流的算法。
图2表示多级别提要段信息方案和相应的多级别提要流，其中根据多媒体流的各段的级别重要性和多级别提要流(H0，H1，H2，…)描述了提要级别(0，1，2，…)。
此处，提要流(H0)由提要级别(0)的提要段组成，提要流(H1)由提要级别(0，1)的提要段组成，提要流(H2)由提要级别(0，1，2)的提要段组成。
多级别提要段信息方案通过对提要段给予重要性级别来在多级别中显示提要流。即，多级别提要段信息方案不是通过使用相对于多级别提要段的物理数据，而是通过使用提要段的段信息和重要性级别信息来描述每个提要段。
但是，常规方法是不便的，因为用户为了浏览用户希望的段或内容，必须使用基于内容的数据区或内容映射中描述的基于内容的数据，对每个滤波或搜索操作输入滤波条件或搜索条件。
为了减轻该不便，常规系统采用了一种方法，该方法通过根据用户的历史记录，多媒体流的内容映射等等组合用户概况信息，自动推荐用户喜欢的节目或仅仅提供用户可能想要的段。
此处，用户概况被存储在便携式非易失存储装置中，例如智能卡，用户终端的固定非易失存储器，多媒体服务器的非易失存储空间。此外，从用户的浏览历史记录自动得知用户概况，或通过预注册用户的编辑对其进行更新。
同时，一般来说大多数用户希望在浏览全部多媒体流之前通过浏览多媒体流的提要来节省时间，以便确定是否观看全部多媒体流。
为此目的，提出了多级别提要流信息方案。利用该多级别提要流信息方案，内容提供者可以使用少量的数据来描述要点的多个版本，并且用户可以对于具有两个小时运行时间的原始流请求10，20和30分钟长度的多种提要流。
但是，由于根据本发明的提供提要流的方法被设计为，以对于理解全部内容的重要性的顺序对各个段给予一个级别，而不考虑用户的各种爱好，所以不能提供反映用户偏好或性格的提要流。
同时，在同时使用多级别提要流信息和多媒体流的基于内容的数据时，有可能满足基于用户查询的对多媒体流的请求。但是，根据本发明的提供多媒体流的方法的不便之处在于，在需要输入提要的条件时，用户必须使用自然语言或其它接口来输入。
因此，本发明的目的是提供一种用于提供用户自适应的多级别提要流的方法，其通过使用用户偏好信息和多媒体流的基于内容的数据，提供具有用户希望长度和反映用户偏好／非偏好的多媒体流。
本发明的另一个目的是提供一种用于提供用户自适应的多级别提要流的方法，其通过使用用户偏好信息和多媒体流的多级别提要段信息方案，提供具有用户希望长度和反映用户偏好／非偏好的多媒体流。
为了实现上述目的，提供一种用于提供用户自适应的多级别提要流的方法，其根据用户偏好信息动态地提供用户自适应的提要流，包括：按多媒体流的类别搜索具有用户偏好／非偏好级别的用户偏好信息；及使用搜索的用户偏好信息和多媒体流的基于内容的数据，根据用户偏好信息将关于多媒体流的多级别提要流信息重建为多级别提要流信息。
此外，根据本发明提供另一种用于提供用户自适应的多级别提要流的方法，其包括以下各步骤：鉴别用户的提要流请求，读出请求提要流的用户的用户偏好信息；根据所读取的用户偏好信息重调整关于多级别提要流的信息的提要段的重要性级别；以及使用提要段的重调整的级别提供用户所请求长度的提要流。
此外，根据本发明提供另一种用于提供用户自适应的多级别提要流的方法，其包括以下各步骤：设置多媒体流的用户偏好类别的偏好／非偏好级别；输入多媒体流的基于内容的数据；以及根据偏好／非偏好级别和多媒体流的基于内容的数据产生关于多媒体流的多级别提要流信息。
本发明的其它优点，目的和特征在下面的说明书中将变得更加明了。
通过参照作为示例给出的但不是对本发明的限制的附图，可以更好地理解本发明，其中：
图1表示根据常规技术的用于描述多媒体流的基于内容的数据的方法的例子；
图2表示根据常规技术的多级别提要段信息方案和相应的多级别提要流；
图3表示根据本发明的用户偏好信息；
图4表示使用多级别提要段信息方案和用户偏好／非偏好信息提供用户自适应的多级别提要流的方法。
本发明涉及一种用于提供用户自适应的多级别提要流的方法，其提供反映用户偏好／非偏好的多媒体流的提要流。该方法通过为用户偏好类别设置用户偏好信息(由偏好／非偏好级别和偏好类别描述的信息)，自动地提供用户自适应的多级别提要流。
因此，下面将说明按用户偏好类别定义多媒体流的内容的偏好级别并根据偏好级别产生提要流的步骤，以便通过滤波提供用户希望的信息。
图3表示根据本发明的用户偏好信息，其中用偏好／非偏好级别描述用户偏好类别(导演，流派，男演员或女演员，运动员，队，…)。
如图所示，如果使用偏好／非偏好级别描述偏好类别，用户可以描述其想要得到的多媒体流，并由此可以得到更好反映用户偏好的多媒体流的提要。
此处，用户偏好信息被存储在便携式非易失存储装置中，例如服务器存储器，客户机装置，和智能卡。
下面对使用偏好信息定义多媒体的提要流的步骤进行说明。
图4表示多级别提要段信息方案和相应的多级别提要流，其表示了一种使用多级别提要段信息方案描述提要级别(0，1，2，…)的多媒体流(MS)的方法，和一种使用用户偏好／非偏好数据描述提要级别(…，-1，0，1，2，…)的多媒体流(MS)的方法。
此处，粗线表示用户偏好的提要段部分，双线表示用户非偏好的提要段部分。
如上所述，在根据本发明的用于提供用户自适应的多级别提要流的方法中，当用户提供多媒体流的适当偏好信息并选择提要级别或提要流的数量时，读出请求提要流的用户的用户偏好信息，根据所读出的用户偏好信息重调整提要段的重要性级别，并提供使用重调整的提要段级别的具有用户请求长度的提要流。
此处，通过比较预存储的用户偏好信息和与多媒体流有关的基于内容的数据，得到多媒体流的信息集。换句话说，其检查基于内容的数据(例如视听对象的操作，视听对象的状态，事件，背景，段信息等等)是否与用户偏好信息一致，从而相对于用户偏好信息中描述的类别反映用户偏好／非偏好。
通过提高用户所偏好的提要段的级别(或降低提要级别的数字)和降低用户所非偏好的提要段的级别(或提高提要级别的数字)，可以根据用户偏好信息来描述在多级别提要段信息方案中的多媒体流。如此描述的提要段信息被构建为具有用户希望长度并包含希望的提要级别信息的多媒体流。
虽然图4将用户所偏好的段和用户所非偏好的段的级别移动描述为一级别移动，如图3所示，可以使用-4～4在多级别中描述对于每个类别的偏好的加权值。
因此，在根据本发明的用于提供多媒体流的方法中，例如，根据用户的各自偏好信息(其中用户A喜欢新闻和情景喜剧但不喜欢体育，用户B喜欢新闻和体育但不喜欢情景喜剧)，可以推荐适当的节目并提供给每个用户。对于所推荐或提供的节目，通过有效地搜索或浏览该节目的提要流，可以向用户提供反映其偏好的多级别提要流。
此外，在根据本发明的用于提供多媒体的方法中，由于用户可以编辑通过从使用用户所用的多媒体流的信息(或历史信息)的先前学习产生的上述用户偏好信息和用户非偏好信息，因此可以向用户提供反映其偏好和非偏好并具有希望长度的多级别提要流，而无需输入额外的查询条件。
由于在不偏离本发明精神或本质特征的条件下可以以多种形式实现本发明，还应理解除非特别指明，上述实施例不受说明书中任何细节的限制，而应该在所附权利要求中定义的精神和范围内广义地理解，因此落入权利要求界限和范围及其等同物内的所有变化和修改都应被所附权利要求所涵盖。
