Abstract: A percussion instrument including a box with at least one wall configured to define a resonant chamber. The at least one wall defines a support area about an opening into the resonant chamber with the support area extending in a support plane. A playing surface is configured to be mounted to the support area to close the opening such that an inner surface of the playing surface extends along the support plane. At least one arcuate string is mounted relative to the at least one wall at an angle such that a portion of the arcuate string is in biased engagement with a contact surface defined by an inner surface of the playing surface or an inner surface of a portion of the at least one wall.

Abstract: A media content broadcast blackout control method, comprising receiving a retune message requesting a blackout of a primary media content broadcast in specific regions, generating a playlist for each region comprising a content key wrapped in a region-specific media key, wherein the content key in the playlists for regions that are not subject to the blackout is configured to access the primary media content broadcast, and the content key in the playlists for regions that are subject to the blackout is configured to access an alternate media content broadcast, providing the playlists to client devices within each region, providing the primary media content broadcast to client devices whose region-specific media key unwraps the content key for the primary media content broadcast, and providing the alternate media content broadcast to client devices whose region-specific media key unwraps the content key for the alternate primary media content broadcast.

Abstract: A dongle for converting remote control instructions from a first wireless medium to a second wireless medium includes a base unit having a base unit housing. A receiver disposed within the base unit housing is operable to receive a remote control instruction via the first wireless medium. A communication module including a communication module housing includes a transmitter operable to transmit the remote control instruction via the second wireless medium. The communication module is coupled to and pivotable with respect to the base unit.

Abstract: A method and system for multi-port aggregation in a digital return path CATV system digitizes each of a plurality of return path signals, splits each of the plurality of return path signals into a low band and an upper band (41), combines each of the plurality of low band signals to form a combined low band signal (43), downconverts each of the plurality of upper band signals from an original frequency range into a new downconverted frequency range (45) and time division multiplexes the plurality of downconverted upper band signals with the combined low band signal to form an aggregate data stream (46).

Abstract: An HFC return path system for digital communication signals using a sampled RF word interface to headend demodulators, provides higher performance equipment at an equivalent or lower cost and more flexible and efficient interfacing and traffic multiplexing. The return path signal from the fiber optic node to the headend/hub is represented ones and zeroes, and the digital return receiver at the headend/hub includes an optical receiver for receiving the serial stream of optical ones and zeroes and converting the optical digital signal to an electrical digital signal, a deserializer for deserializing the serial stream of digital words and synchronization information into parallel digital words, a digital filter for processing the deserialized digital words to interface digitally to an application receiver and a digital interface for interfacing and forwarding the processed parallel digital words to the application receiver.

Abstract: Set-top terminals utilized in broadband broadcast networks are becoming increasingly intelligent. Upgrading the operation of such terminals periodically requires upgrading the software, particularly the operating system, of the programmable processor which controls the terminal operation. To facilitate frequent upgrades, the network will carry a cyclic broadcast of a packetized data file containing the operating system. Periodically, a terminal will capture and store the broadcast operating system. In the preferred embodiment, the broadcast includes operating system files for a number of different terminal types and data identifying the current broadcast version of the operating system for each type of terminal. The terminal will check the broadcast version number for its terminal type operating system.
