Abstract: A method and apparatus for eliminating the apparent delays in a televised presentation between local program content and delayed program content received from a remote location, e.g., via satellite. Local and remote program signals are delayed by the system and method and then combined to provide an output program signal where there is no apparent delay between the content from the different program sources. The delay of the input signals is preferably automatically adjusted such that the start of the program output is not delayed and may be obtained by imperceptibly altering the input program content, e.g., using delay buffers.

Abstract: A system and method for modifying or enhancing the operation of a palmtop computer which intercepts keystrokes from the keyboard, reads the keyboard characters corresponding to the keystrokes, reads display data, and based on the current state of the display, the sequence of previous keystrokes, and other variables, either delivers the current keystroke character to the application program without change, with additional or replacement characters, or dumps the current keystroke character. The system and method alters the "look-and-feel" of the computer by providing easier ways to interact by the keyboard with the built-in application programs. The system and method may monitor display data between keystrokes and determine the identity of the particular active application program based on what the display screen is displaying. Keystrokes and the display state are monitored to determine if there are additional functions to be executed for the active application program.
