Abstract: A system and method of removing noise in a bitstream is disclosed. Based on the segment classifications of a bitstream, each segment or portion is encoded with a different encoder associated with the portion model and chosen from a plurality of encoders. The coded bitstream for each segment includes information regarding which encoder was used to encode that segment. A circuit for removing noise in video content includes a first filter connected to a first input switch and a first output switch, the first filter being in parallel with a first pass-through line, a second filter connected to a second input switch and a second output switch, the second filter connected in parallel with a second pass-through line, and a third filter connected to a third input switch in a third output switch.

Abstract: The invention provides a system and method for integrating multimedia descriptions in a way that allows humans, software components or devices to easily identify, represent, manage, retrieve, and categorize the multimedia content. In this manner, a user who may be interested in locating a specific piece of multimedia content from a database, Internet, or broadcast media, for example, may search for and find the multimedia content. In this regard, the invention provides a system and method that receives multimedia content and separates the multimedia content into separate components which are assigned to multimedia categories, such as image, video, audio, synthetic and text. Within each of the multimedia categories, the multimedia content is classified and descriptions of the multimedia content are generated. The descriptions are then formatted, integrated, using a multimedia integration description scheme, and the multimedia integration description is generated for the multimedia content. The multimedia description is then stored into a database. As a result, a user may query a search engine which then retrieves the multimedia content from the database whose integration description matches the query criteria specified by the user. The search engine can then provide the user a useful search result based on the multimedia integration description.

Abstract: A method and system for description of synthetic audiovisual content makes it easier for humans, software components or devices to identify, manage, categorize, search, browse and retrieve such content. For instance, a user may wish to search for specific synthetic audiovisual objects in digital libraries, Internet web sites or broadcast media; such a search is enabled by the invention. Key characteristics of synthetic audiovisual content itself such as the underlying 2d or 3d models and parameters for animation of these models are used to describe it. To represent features of synthetic audiovisual content, depending on the description scheme to be used, a number of descriptors are selected and assigned values. The description scheme instantiated with descriptor values is used to generate the description, which is then stored for actual use during query/search.

Abstract translation: 用于描述合成视听内容的方法和系统使人，软件组件或设备更容易识别，管理，分类，搜索，浏览和检索这些内容。 例如，用户可能希望在数字图书馆，互联网网站或广播媒体中搜索特定的合成音像对象; 通过本发明实现了这种搜索。 合成视听内容本身的关键特征，例如基本的2d或3d模型和这些模型的动画参数用于描述。 为了表示合成视听内容的特征，根据要使用的描述方案，选择多个描述符并分配值。 用描述符值实例化的描述方案用于生成描述，然后在查询/搜索期间将其描述为实际使用。
