Abstract: A TV graphical user interface (GUI) is provided to enable a user to input antenna location information required for setting up a dish antenna. When the TV GUI is set in a dish set-up mode, the user may activate a U.S. map button to display a map of the United States or another area on the earth's surface. When a remote pointing device is directed at a point on the map that represents the current location of a satellite receiver, the TV GUI displays a regional map that shows in more detail a region where the receiver is located. When the user selects the receiver location within the regional map, the CPU determines the latitude and longitude values of the selected location, and calculates magnetic north and elevation angles for the antenna installation. To provide the user with visual feedback, the TV GUI may indicate the city nearest to the selected location, and a distance to the nearest city.

Abstract: A method and arrangement for monitoring the audio portion of a broadcast signal includes a keyword listening device.

Abstract: A graphics data decompression arrangement in a TV set top box that includes a system ROM for storing graphics data broken down into tiles, each of which is identified by a unique index number. The index numbers that identify the tiles of graphics data required to be included in a current picture on a TV set screen are written into a DRAM. An MPEG decoder reads the index numbers to convert them into a graphics address signal supplied via a ROM address bus to the system ROM to indicate the addresses of the required tiles of graphics data. In response, the required tiles are fed to the MPEG decoder for decompression in accordance with an MPEG decompression algorithm. A time-division multiplexing scheme allows the ROM address bus to be used for transmitting to the system ROM an address signal from a CPU that indicates where information required for CPU operations is located in the system ROM. In response to the CPU address signal, the required information is fed to the CPU.

Abstract: A system for providing a user controllable picture-in-picture formatted signal to a television is provided with a fast modem that interconnects the system with a computer network, such as the Internet. In order to allow a user to interact with the Internet, yet still enjoy video programming, the system has a picture-in-picture selection that a user controls to determine which video source (e.g., digital satellite signal, digital video disk signal, Internet graphics) will form the main picture displayed on the television, and which will form the picture-in-picture. A conventional television may be used with the system to display the signal, since it is already formatted in a picture-in-picture format at the output of the system.

Abstract: A substrate for surface-enhanced analytical procedures, such substrates prepared for use in specific procedures to detect specific binding partner molecules, and a method for making them. The substrate is a body having a substrate surface on which there are randomly spaced apart metal islands. A continuous layer of coupling agent coats the islands and any intervening substrate surface. First binding partner molecules are bonded to the coupling agent. These are specifically attractive to specified second partner molecules for an analytical procedure for detecting the presence of, and perhaps the concentration of second partner molecules, or in some procedures, of a specified third binding partner molecule which becomes bonded to the second binding partner molecule. The thickness of the coupling agent layer is selected to improve the sensitivity of a given analytical procedure for detecting or measuring the specific binding partner molecule.
