Abstract: A signal correcting and compensating system including a signal transceiver, a personal computer, a signal database, and a signal correction component. A signal sent by a remote control may be subjected to a distortion causing nuisance before it is received by a transceiver, possibly preventing the signal from being identified. A signal correction component may correct and/or compensate for errors by evaluating the signal and determining a margin of error for identifying information within the signal.

Abstract: A method for calculating an extended hamming checksum and applying the extended hamming checksum to a data packet, the method comprising forming a packet extended hamming checksum mask, calculating a hamming code, calculating an extended hamming checksum using the packet extended hamming checksum mask and the hamming code, and inserting the extended hamming checksum into the data packet.

Abstract: A method and system are provided for displaying animations of menus solely in response to a cursor pointing in proximity to a menu marker that is displayed on a video display. Multiple menu markers may be displayed on the video display and each menu marker may be associated with a different menu. The animation may produce the visual effect of the menu sliding out of an associated menu marker. A dynamic control mechanism may be used to control the performance of the animation of the menu to account for different platforms and different processing states. In addition, audio output may accompany the animation of the menu.
