US Classification:

7155001

Abstract:

A method is described for efficiently delivering a presentation of web content comprised of a media, such as audio or video content, having defined time increments, together with one or more other content sources, such as images or events to be displayed on a monitor, synchronized so that the one ore more other images or events are displayed at predetermined time increments in the media presentation. Furthermore, the entire presentation is delivered in streaming fashion, so that the end user does not have to wait for the entirety of the content data to be downloaded before starting the presentation, but rather can start viewing and listening to the presentation after a relatively short delay period. The media data and the other content need not reside at a single server source. An authoring tool for creating such composite time-synchronous content automatically determines the necessary information for scheduling player requests to the servers.

Abstract:

Video, stills, panorama, sound and all forms of media as Rich Media in a Multimedia Vehicle Repository (MVR) file editable with a Rich Media Content description file. The Rich Media Content description file enables users to specify a vocabulary that defines the media elements and relations among the media elements thereby permitting the users to easily create and edit the Rich Media Content and compose various raw or compressed Rich Media components using any text editor. A multimedia authoring server side processor accepts the raw formatted Rich Media Content along with description text file in XML format and outputs the Rich Media, text and graphic components as an edited MVR file in accordance with user's design for execution on a multimedia player.

International Classification:

G06F017/24

US Classification:

707/500100, 707/530000

Abstract:

An automatic, multi-stage rich media content creation system includes a network based server executing an operating system, a text editing program, typically XML editor, and an authoring or batch processing program for combining Rich Media in a Multimedia Vehicle Repository (MVR) file. Video, stills, panoramas, sound, film, etc are combined as raw Rich Media from one or more sources and transmitted to the server in a framework over a digital network. The raw Rich Media is incorporated into the framework as a series of related frames. The raw Rich Media is stored on a storage device, typically a disk at the network based server. A creator using a standard graphical or text editing tools has access to the raw media assets on the disk for preparing a textual specification description, typically XML in an electronic template of desired Rich Media content. The template and raw media assets are transmitted by the creator to the server for combining the raw media assets and the XML textual specification in the template as a composed MVR file using the batch-processing program. The composed MVR file and textual specification may be returned to the creator for further editing of the specification, if necessary, and/or stored on the server disk for access by other creators. The template based, composed or edited MVR file of Rich Media content and related textual specification can be transmitted to other servers on the network for automatic, multistage creation of Rich Media content by several user groups. One user group can create a template based, composed or edited MVR file which another group accesses via the network to inject other content into the template for revising the XML text specification to create another embodiment of the Rich Media content.

Appl. No.:

09/880309

Inventors:

Hua Chen - Brooklyn NY, US

International Classification:

G06F017/60

US Classification:

705/035000

Abstract:

The present invention involves a method and an apparatus capable of calculating, in real time, option-embedded coupon bearing bonds by option adjusted spread and linear approximation. The linear approximation uses a first order partial derivative to calculate a vector of sensitivities of bond price against yield curve by which an nth order linear approximation of the bond price can be approximated. The apparatus comprises a plurality of trader's workstations, one of which may serve as an option adjusted spread lattice engine for full lattice computation. The trader's workstations may be actuated by a triggering object, which receives yield curve, bond price, spread, volatility and other bond information updates from a database server. For each security, the Lattice Engine uses the lattice method to compute the price of the security and a vector of partial derivatives of the security price with respect to the yield curve. While other workstations, upon receiving any update of the yield curve, use the results of the Lattice Engine to perform first order approximation of the security prices. Since linear approximation is a simple calculation, the price update of a large number of securities can be carried out in real time. Because the Lattice Engine recalculates the first order partial derivatives when the yield curve has changed significantly, the linear approximations are very accurate in general.

International Classification:

G01J 400

US Classification:

356369

Abstract:

An apparatus for determining electrical conductivity of a surface of an object. The apparatus comprises a first polarizer for polarizing light incident upon the surface of the object. The apparatus also comprises a camera mechanism for receiving the polarized light reflected from the surface of the object and identifying the electrical conductivity of the surface of the object from phase retardance of polarization of the polarized light upon reflection from the surface of the object. The present invention pertains to a method for determining electrical conductivity of a surface of an object. The method comprises the steps of polarizing light. Next there is the step of reflecting the polarized light off the surface of the object. Then there is the step of receiving the reflected polarized light at a camera mechanism. Next there is the step of converting the received polarized light into a corresponding electrical signal with the camera mechanism.
