Abstract:
First, a delivery delay, i.e. the time it takes for a content to be captured and a representative frame made available (i.e. delivered), is determined. Second, a video capture interval, i.e. a minimum time delay requirement between stable captured content frames, is determined. In other words, the recycle time-period after which it is safe to change frame content during a capture interval without impacting a prior stable video frame in the pre-delivery stage is determined.

A method having corresponding apparatus and computer-readable media embodying instructions executable by a computer to perform the method comprises: in response to a request to print an image stored on a first website, automatically downloading an image editing pipeline for the image from a second website in response to the request, wherein the image editing pipeline describes one or more image editing operations for the image; automatically downloading the image from the first website; automatically generating an edited image based on the image and the image editing pipeline; and automatically printing the edited image on a printer.
Abstract:
A method for correcting a projection from a plurality of digital projectors is provided. The method includes receiving as an input a matrix which maps each pixel to be projected to a captured pixel that includes a row value and a column value and detecting a shift with respect row or column values in the matrix. The method further includes determining attributes of the shift, wherein the attributes include a type for the shift and an overlap length for the shift. A gradient length is determined from the overlap length. A gradient of pixel weightings is generated for each gradient length. The pixel weightings are uniformly sloping and are associated with pixels in the gradient length and neighboring pixels. Intersecting gradients re merged and a list that includes common points and diagonal points is created from the merging process. The method operations may be embodied as code on a computer readable storage medium.

Abstract:
Apparatus having corresponding methods and computer-readable media comprise a first input circuit to receive first data describing a first region of an image, the first region identified based on user markups of the image; a second input circuit to receive second data describing at least one of a second region of the image, the second region identified by an analysis of the image, and a third region of the image, the third region identified by an analysis of an environment that produced the image; and a synthesizer to identify a fourth region of the image based on the first data and the second data.
Abstract:
Methods and systems are disclosed for processing image frames to reduce the bandwidth requirements. Embodiment of the present invention may include mode-specific image frame rendering in photorealistic and non-photorealistic modes, such as outline and cartoon modes. In embodiments, update regions may be identified and reduced by an edge position mask. In embodiments, update regions may be bounded by rectangles and such regions may be reduced in number by merging regions together using various no-cost or cost approaches. To improve compressibility, regions to be transmitted that do not require updating at the receiver may be encoded as transparent.
Abstract:
A method and system for providing technical support for networked devices includes a first client component on a networked device having a conferencing application to enable communication exchange with a second client component. A server component is configured to distribute video and audio data streams to the first client component and the second client component in a conference session. A conference channel communication connection is established over which the video and audio data streams are carried between the first client component, the server component, and the second client component, and a back-channel communication connection is established for transmission of diagnostic and status information. A service call is managed by a service center dispatcher, who connects a technician client and a networked device client in a multi-party conference hosted on one of a plurality of load balanced servers.
Abstract:
A multi-participant videoconference system incorporating a back-channel connection and a client video mixer is disclosed. The multi-participant videoconference system includes a client component and a server component. The server component provides a composite conference video signal to the client component. A region is defined in the composite conference video signal and the size and coordinates of the region are communicated to the client component by the server component over the back-channel. The client component captures local video and mixes local video into the composite conference video signal using the size and coordinates received from the server component for display.
