Abstract: A frame buffer system includes a first frame buffer containing a first set of pixels, and a second frame buffer containing a second set of pixels. A first register is connected to an output of the first frame buffer, wherein the first register a number of pixels is stored in which a group of bytes of data is stored for each of the number of pixels. A second register is connected to an output of the second frame buffer, wherein the second register a number of pixels is stored in which a group of bytes of data is stored for each of the number of pixels. A selection logic is connected to the first frame buffer and to the second frame buffer. The selection logic selectively selects pixels to be read from the first frame buffer and the second frame buffer into the first register and the second register. A multiplexer has a first input connected to an output of the first register, a second input connected to an output of the second register, and an output configured for connection to a digital to analog converter.

Abstract: A method and apparatus for remote control of electronic devices includes one or more processing units, a memory system, one or more I/O controllers, controlling various input/output devices such as a keyboard, a mouse, a display device, communications adapters and the like, a bus which connects the processing units, the memory system, and the I/O controllers, one or more transducers adapted to convert electronic signals to wireless communications signals and one or more application programs executable by the processor units for controlling generation and transmission of wireless communications signals for remote control of one or more electronic devices. A typical application is the control of transmission of infrared signals to remotely control consumer electronics equipment.
