The system includes a constraint-based registry server and a plurality of devices. The constraint-based registry server is coupled to the plurality of devices for publishing or registering spots, managing places and authenticating membership and places. The constraint-based registry server includes a data store for constraint metadata, an authentication module, a spot manager module, a place manager module and a query response module. The devices are adapted to collect field values, create spots, access places, and interact and share information with other spots. In one embodiment, the devices include a constraint collection module, a spot creation module, a query module, a challenge creation module, a presentation module, a challenge response module, a spot action module and a spot communication module. The present invention also includes a number of methods for creating a spot, for generating and approving a challenge, for direct communication or sharing of documents, for performing an action based upon information space membership and for searching for available places.

Techniques for positioning images in an electronic document. The images may encode information that can be decoded by devices configured to read the images. An area within the electronic document for positioning the image and a set of one or more colors to be used for the image are determined. The determined area and set of colors are such that the image when positioned in the electronic document blends in with the contents of the electronic document while still being clearly visible for reading by reader devices that are configured read and decode the information encoded by the image.

A system for displaying video on electronic paper displays to reduce video playback artifacts comprises an electronic paper display, a video display driver, a video transcoder, a display controller, a memory buffer and a waveforms module. The video display driver receives a re-formatted video stream, which has been processed by the video transcoder, from the memory buffer. The video display driver directs the video transcoder to process the video stream and generate pixel data. The video display driver loads waveforms into the frame buffer and updates display commands repeatedly to activate the display controller until the end of the video playback. The video display driver directs copying video frames sequentially one by one from the memory buffer to the frame buffer in real time during the video playback. The video transcoder receives a video stream for presentation on the electronic paper display and processes the video stream generating pixel data that is provided to the display controller. The present invention also includes a method for displaying video on an electronic paper display.

A system for displaying video on electronic paper displays to reduce video playback artifacts comprises an electronic paper display, a video transcoder, a display controller and a waveforms module. The video transcoder receives a video stream on for presentation on the electronic paper display. The video transcoder processes the video stream and generates pixel data that is provided to the display controller. The video transcoder adapts and re-encodes the video stream for better display on the electronic paper display. In one embodiment, the video transcoder includes one or more of the following processes: encoding the video using the control signals instead of the desired image, encoding the video using simulation data, scaling and translating the video for contrast enhancement and reducing errors by using simulation feedback, past pixels and future pixels. The present invention also includes a method for displaying video on an electronic paper display.

A multimedia printing device receives multimedia data, processes it, and outputs it, thereby enhancing the handling and use of such data. In an embodiment, the processed data are output in a variety of formats, including on video paper, through a multimedia broadcast, or a bar code pointer to a digital archive. In another embodiment, the multimedia printing device receives multimedia data and uses the data to perform multimedia and video localization on the peripheral devices that generate the multimedia data. In another embodiment, the multimedia printing device carries out commands to capture and process multimedia data, including by inserting multimedia objects into existing documents.
