20080228825 | SYSTEM AND METHOD OF ORGANIZING DATA TO FACILITATE ACCESS AND STREAMING - File formats systems and methods are disclosed that provide a framework that integrates concepts, such as objects based audio-visual representation, meta-data and object oriented programming, to achieve a flexible and generic representation of the audiovisual information and the associated methods to operate on the audiovisual information. A system and method are disclosed for storing data processed from presentation data. The data is stored according to a method comprising coding input presentation data by identifying objects from within the presentation data, coding each object individually and organizing the coded data into access layer data units. The access layer data units are stored throughout a plurality of segments, each segment comprising a segment table in a header portion thereof and those access layer data units that are members of the respective segment, there being one entry in the segment table for each access layer data unit therein. A plurality of extended segments are also stored, each of the extended segments further comprising one or more of the access layer data units that include protocol specific data, the extended segments each represented by a extended segment header. The data of an accessible object is also stored, including an accessible object header and identifiers of the plurality of extended segments, each of the extended segments being a member of the same object. | 09-18-2008 |
20110002508 | DIGITALLY-GENERATED LIGHTING FOR VIDEO CONFERENCING APPLICATIONS - A method of improving the lighting conditions of a real scene or video sequence. Digitally generated light is added to a scene for video conferencing over telecommunication networks. A virtual illumination equation takes into account light attenuation, lambertian and specular reflection. An image of an object is captured, a virtual light source illuminates the object within the image. In addition, the object can be the head of the user. The position of the head of the user is dynamically tracked so that an three-dimensional model is generated which is representative of the head of the user. Synthetic light is applied to a position on the model to form an illuminated model. | 01-06-2011 |
20110072466 | Browsing and Retrieval of Full Broadcast-Quality Video - A method includes steps of indexing a media collection, searching an indexed library and browsing a set of candidate program segments. The step of indexing a media collection creates the indexed library based on a content of the media collection. The step of searching the indexed library identifies the set of candidate program segments based on a search criteria. The step of browsing the set of candidate program segments selects a segment for viewing. | 03-24-2011 |
20110103484 | Scalable Video Encoder/Decoder with Drift Control - A system, method and computer-readable media are introduced that relate to data coding and decoding. A computing device encodes received data such as video data into a base layer of compressed video and an enhancement layer of compressed video. The computing device controls drift introduced into the base layer of the compressed video. The computing device, such as a scalable video coder, allows drift by predicting the base layer from the enhancement layer information. The amount of drift is managed to improve overall compression efficiency. | 05-05-2011 |
20120033743 | SYSTEM AND METHOD FOR GENERATING CODED VIDEO SEQUENCES FROM STILL MEDIA - The invention provides a system and method that transforms a set of still/motion media (i.e., a series of related or unrelated still frames, web-pages rendered as images, or video clips) or other multimedia, into a video stream that is suitable for delivery over a display medium, such as TV, cable TV, computer displays, wireless display devices, etc. The video data stream may be presented and displayed in real time or stored and later presented through a set-top box, for example. Because these media are transformed into coded video streams (e.g. MPEG-2, MPEG-4, etc.), a user can watch them on a display screen without the need to connect to the Internet through a service provider. The user may request and interact with the desired media through a simple telephone interface, for example. Moreover, several wireless and cable-based services can be developed on the top of this system. In one possible embodiment, the system for generating a coded video sequence may include an input unit that receives the multimedia input and extracts image data, and derives the virtual camera scripts and coding hints from the image data, a video sequence generator that generates a video sequence based on the extracted image data and the derived virtual camera scripts and coding hints, and a video encoder that encodes the generated video sequence using the coding hints and outputs the coded video sequence to an output device. The system may also provide customized video sequence generation services to subscribers. | 02-09-2012 |
20130019274 | System and Method for Sharing Information - A novel mechanism is disclosed by which a sender can direct information such as an audiovisual signal to a particular recipient's audiovisual display device, such as a cable television set and, thereby, share information between the sender and the recipient. In one embodiment, a calling party originates a telephone call and associates that telephone call with audio-visual information that exists on the caller's personal computer or on an Internet server. The called party answers the call, and can tune an associated cable television to the appropriate channel in order to view the audio-visual information. In another embodiment, the caller is a hotel guest and the called party is a hotel concierge and vice versa. The concierge provides information to the hotel guest such that the hotel guest can tune in to a channel on their hotel television set and access the information. | 01-17-2013 |
