US Classification:

707104, 707 3, 707 5, 707 10, 707501, 707514, 709224, 709231, 709217

Abstract:

A method of adapting multimedia content to a client device, wherein the multimedia content includes one or more items and the client device has capabilities and resources associated therewith, is provided. The method includes transcoding the multimedia content into a plurality of transcoded content versions, wherein the plurality of transcoded content versions have different modalities and resolutions associated therewith. Next, the transcoded content versions that are not compatible with client device capabilities are filtered out. Then, at least a portion of the resources associated with the client device are allocated among the one or more items of the multimedia content. Lastly, one or more of the transcoded versions of the multimedia content are selected to generate a customized content based on allocation of the client device resources.

US Classification:

382110, 382141, 382170, 382199, 382203, 348 89

Abstract:

The present system and apparatus use image processing to recognize object size with a scene. The system includes novel image processing apparatus and method to segment one or more object images from a background image of the scene. A processed image (that can be used to characterize size features) of the object(s) is then compared to stored reference images. The object size is recognized when a match occurs. The system can recognize object sizes independent of number of objects present and the objects may be touching each other and overlapping. The system can be trained to recognize object sizes that it was not originally programmed to recognize.

US Classification:

707523, 707522, 707513

Abstract:

Systems, methods and computer program products are provided for modifying Web content files, such as HTML files, for display via pervasive computing devices that have smaller displays and various performance limitations compared with desktop computing devices. Upon receiving a request from a pervasive computing device for an HTML file, the HTML file is analyzed for a link to a content modification file that contains information about how to modify elements within the HTML file so as to render the HTML file displayable via the pervasive computing device.

US Classification:

709231, 707 3, 707101, 7075001, 7071041, 709232

Abstract:

A framework is provided for describing multimedia content and a system in which a plurality of multimedia storage devices employing the content description methods of the present invention can interoperate. In accordance with one form of the present invention, the content description framework is a description scheme (DS) for describing streams or aggregations of multimedia objects, which may comprise audio, images, video, text, time series, and various other modalities. This description scheme can accommodate an essentially limitless number of descriptors in terms of features, semantics or metadata, and facilitate content-based search, index, and retrieval, among other capabilities, for both streamed or aggregated multimedia objects.

US Classification:

707 10, 707103, 7071041, 709216, 709224

Abstract:

A system and method for describing and managing media assets comprising a two-pronged solution: (1) a Digital Library to provide a centralized repository of the media assets and (2) a standard description scheme that will allow interoperation of a variety of tools and processes required for managing media assets. In the invention, a description scheme is provided that addresses information needed for managing media assets independent of their type. In addition, the invention provides a description scheme for logical collections of media assets. The media asset management description scheme may be based on eXtensible Markup Language (XML), to ensure maximum interoperability.

International Classification:

G06F 1721

US Classification:

707513, 707100

Abstract:

A method for translating data from one representation or schema to another representation or schema. Example data encoded in both the schemas is used to generate a translator. This translator is then used for automatically translating data from one schema to another. The translator is computed by finding corresponding paths for matched data elements. When new data is presented in one schema, the translator then gives the translation for the paths of data elements in the data. A translated data is then constructed by using these translated paths. Possible applications in the Internet domain, include but are not limited to: EDI; search engines; content ingestion; content customization; data delivery; and data retrieval. Specific examples are shown for generating a translator and translating data between various schema including HTML, XML and extensions thereto such as SpeechML.

International Classification:

G06K009/36

US Classification:

382232, 382100

Abstract:

A method and apparatus for selecting at least one transcoding method for manipulating multimedia data for delivery on the basis of analysis of the content of the multimedia data. Many possible transcoding operations can be performed on multimedia data to adapt it to constraints in delivery and display, processing and storage of client devices. The selection of specific transcoding operations can be made by first analyzing the features, purposes and relevances of the individual multimedia objects within the multimedia documents, then by selecting the transcoding alternatives according to the results of the analysis. Based on the analysis, different transcoding algorithms can be applied to different content, less than all of the content can be transcoded, groups of multimedia objects can be transcoded, etc.

US Classification:

709205, 709223, 709245

Abstract:

The invention provides a system adapted to enable contextual collaboration within a computer network. The invention provides a collaboration manager that supports manipulation of collaboration spaces. The collaboration spaces contain one or more collaboration elements that have potentially different collaboration modalities. The context manager maintains resources and resource interrelationships within contexts. The resources can include collaboration elements, processes, tasks, business objects, users, and/or roles. A view generator selects a set of the resources to be displayed to a user of the computer network. The invention also includes an interface adapted to allow applications to specify commands to manipulate collaboration spaces, commands to maintain resources and resource interrelationships within contexts, and queries for context-sensitive views.
