Abstract: An interactive entertainment system that includes a universal puzzle piece for each game or activity participant. The puzzle piece includes an updatable display displaying a first graphic image. The system includes an interactive display device with a display surface with an update mechanism that is operable such as by a controller, when the puzzle piece is in a predefined proximate position, to program the updatable display to update the first graphic image into a second graphic image. The updatable display includes an electrophoretic display layer storing the second graphic image. A transparent electrode layer is provided on a first side of the electrophoretic display layer. The update mechanism includes a puzzle piece update pad for receiving a second side of the electrophoretic display. The update pad includes a conductor layer or bottom conductor providing an electrical connection with the second side to provide the update to the first graphic image.

Abstract: Methods, systems, and apparatus, including computer program products, for changing digital broadcast channels. In one implementation, upon receiving a request for switching to a new channel in a digital broadcast receiving device, the device switches from a power saving mode, in which the device processes time-slices only for the currently selected broadcast channel, to a channel changing mode, in which broadcast data is buffered for more than one broadcast channels in anticipation of channel surfing. In another implementation, the user's perception of the channel change delay is mitigated by displaying channel information about the newly selected channel.

Abstract: A recorder system contains a media key block (MKB) and selectively writes protected content into a recording medium according to the following content protection logic, to combat theft of the protected content: If the medium does not have a MKB, then the recorder writes its stored MKB into the medium and writes protected content into the medium. If the medium has a MKB that is older than the stored MKB in the recorder, then the recorder writes its stored MKB into the medium before re-encrypting and writing protected content into the medium. If the medium has a MKB that is newer than the stored MKB, then the MKB in the medium is used for content protection. The recorder may store the newer MKB in non-volatile memory, effectively updating its previous stored MKB, so the recorder will have the most recently observed MKB for content protection use.

Abstract: An apparatus for use as a flying entertainment vehicle. The apparatus includes a lift system, such as a parawing, that is inflated by air to generate lift and further includes a vehicle frame attached to the lift system such as by suspension lines that also space the lift system apart from the vehicle frame. The apparatus includes a thrust assembly supported on the vehicle frame that is operable to propel the vehicle at a flight speed at which the lift system is operated, e.g., the parawing is inflated, to generate lift to suspend the vehicle frame above the ground. The apparatus includes show elements that may be supported on or by the vehicle frame and be configured to be lift neutral. The show elements function to distract observers away from the lift system such as by appearing to provide the lift or features that cause the vehicle frame to fly.
