Abstract: Some embodiments provide tools that allow a user to share content on one device with multiple other users using different devices. The content sharing tools allow the user to (1) create a shared stream that represents a set of shared content and (2) invite one or more recipients to subscribe to the shared stream. When a recipient subscribes to the shared stream, the set of content is streamed across one or more of his or her devices. In some embodiments, a control server facilitates the sharing of content by managing control data associated with different shared streams.

Abstract: A method of generating halftone output on an output device. The method includes retrieving at least one table which associates gray levels with halftone results for a region of an output frame including more than one pixel, determining a reference gray level for a tile of an output frame including more than one pixel, using the at least one table to determine a halftone result for the reference gray level, storing the halftone result for the reference gray level to the tile of the output frame, and delivering the output frame to the output device. The table may be generated from a set of thresholds, which may be a threshold array. A first table may associates gray levels with codes and a second table may associates codes with halftone results, and the method may include converting the reference gray level to a reference code with the first table and converting the reference code to the halftone result for the reference gray level with the second table.
