A video sequence control system that includes an input video frame buffer and an output video frame selection component is described. The input video frame buffer receives input video frames from a video source. The output video frame selection component determines the video frame to be output according to a scheduler that provides timing information and modulation information. The timing information includes information regarding when a video frame will be output. The modulation information varies dependent upon the frame types available to be output, wherein the available frame types include at least image frames from the input video frame buffer and functional frames, wherein the at least image frames and functional frames are output according to a pattern defined by the scheduler. In addition based on the timing information, a synchronization output signal is output corresponding to the output of the functional frame.

A localization method for setting the locale of a configurable device is presented. The first portion of the localization transmits localization selections for a target locale to a configurable device. Localization selections are initially set on an interrogator device and then transmitted wirelessly using RFID or other technologies from the interrogator device to a tag coupled to the configurable device. A second portion of the localization receives localization selections for a target locale on the configurable device. A tag receives from an interrogator device one or more localization selections for the target locale on the configurable device. These localization selections are stored on the tag until the configurable device is powered-on. Device initialization causes another portion of the localization to set a target locale on a configurable device. Firmware accesses localization selections previously stored on the tag and then sets the default localization selections in the firmware for the device.

A method and system of tracking documents uses tags and a workflow. Initially, a workflow is developed for each document or type of documents using a state diagram. The workflow specifies a subset of one or more destinations that the document is allowed to travel and a sequence for this travel. A tag is associated with each document to enable tracking of the document as it passes the one or more readers in the various destinations. These tag readers in turn report back position information on the document to assist in locating the document. A comparison between the state diagram for the workflow and the position information gathered from the tag readers determines if the document is outside the desired workflow. An alert is generated when the document is outside the workflow and not being processed as intended.

Provided is a method and apparatus for performing discovery between devices in a network. Using event-driven discovery, devices conserve energy resources and more rapidly join a given network. The event-driven discovery detects a common-event associated with a first device preparing to communicate with a second device. The first device then discovers the second device in response to detection of the common-event. For example, this common-event could be a handshake with another person. During discovery, the first and second devices exchange respective information and optionally may establish a communication session to exchange further information if desired.

When editing a digital image that has previously been saved in a lossy manner (whether such losses result from the editing operations and/or from inherently lossy image file formats such as JPEG), each additional editing session typically compounds the overall losses. As an alternative, we disclose creating and storing a proxy for an edited image, the proxy including a baseline image and a series of meta data representing editing operations performed on that image. During a subsequent editing session, the edited image can be partially or wholly reconstructed by applying the meta data to the baseline image, resulting in a comparatively lossless version thereof. The reconstructed image can be used as a starting point for additional edits, thereby minimizing the compound losses that would otherwise have resulted.
