Abstract: The disclosure relates generally to buffering and presenting content. Multiple pause buffers may be created and maintained so that users can jump within the content of a channel. If buffered content is not available, the user may be offered similar content that is available as on-demand content, or as other recorded content, for example, stored on a digital video recorder. If a commercial is playing when the new channel is selected, a buffered portion corresponding to an earlier portion of the content may be presented instead of the commercial.

Abstract: A puzzle game comprising of a series of paths on a defined number of coaxial circles, such that the number of coaxial circles are two or greater, wherein rotations of the circles cause different pathways on adjacent circles to align, thereby extending the pathways across the circles. Pathways are defined in such a way that a given player will be able to rotate the circles in such a way wherein a path from the outer edge of the outermost circle will be able to be followed through paths in adjacent circles continuing through the centermost circle whereupon the path when continued will be taken back through adjacent circles until thereby reaching the outer edge of the outermost circle, constituting a winning scenario. Puzzles may have an arbitrary number of winning scenarios, but certain more difficult puzzles will include a single pathway that satisfies the winning condition.
