Abstract: Systems are provided for converting high definition pictures or data to lower definition images using wavelet transforms. In the preferred embodiments, the wavelet transforms are be used in either the transmission/coding or reception/decoding phase for enabling a more efficient conversion of the signal and providing a more robust and accurate output. The wavelet transforms may be applied to conventional systems to enhance performance or entire transmission and reception systems may be designed where the wavelet transforms are applied to the data for coding, decoding and decimation operations.

Abstract: A TV graphical user interface provided on a TV screen includes a graphical channel changer for enabling a user to select a required TV channel among about 1000 channels carried by a satellite TV system. The graphical channel changer contains a vertical channel bar composed of channel boxes that display numbers and logos of selected TV channels. To switch the TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. Up and down scroll bars, that allow the user to scan through the entire list of TV channels, extend beyond a safe area on the screen provided to accomodate a picture to overscan conditions. A direct access bar is arranged so as to cause the channel boxes to display numbers and logos of a selected group of channels when the user directs the pointing device at the area of the direct access bar that represents the selected group of channels.

Abstract: A method and an apparatus for converting a high definition image to a relatively lower definition image is provided. Image data encoded with a discrete cosine transform (DCT) is decoded using an inverse wavelet transform (IDWT). A fast inverse discrete wavelet transform (FIDWT) is also provided that reduces the number of multiplication operations relative to the IDWT. Image data is also encoded using a discrete wavelet transform (DWT) and then decoded using an (IDWT).

To switch a TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. Up and down scroll bars, that allow the user to scan through the entire list of TV channels, dynamically alter their size in accordance with the position of the TV channel being currently scanned to provide the user with visual feedback. A relative position indicator is arranged between the up and down scroll bars.

Abstract: A graphical user interface (GUI) for a TV receiver combines a graphical channel changer with an electronic program guide to enable a user to quickly and seamlessly go from a TV channel selection mode to a TV program selection mode. The graphical channel changer includes a vertical bar composed of channel boxes that contain number and logos of available TV channels. The user may tune the TV system to any one of the TV channels by directing a remote pointing device at the channel box that represents that TV channel. When the user switches to the program selection mode, the GUI transfers to the electronic program guide for displaying vertical program bars arranged in alignment with the channel boxes to show information on TV programs for the TV channels represented by the corresponding channel boxes.

A program guide that contains a list of TV programs may be provided based on the channel changer. Vertical program bars that display TV programs are aligned with the channel boxes indicating TV channels that carry the corresponding TV programs. An arrange guide mode is provided to enable the user to arrange the program guide in order of TV channel numbers, or in alphabetical order according to names of TV channels or TV programs.

Abstract: A method and an apparatus for processing a high definition image using both an inverse discrete cosine transform (IDCT) and an inverse discrete wavelet transform (IDWT) to provide a relatively lower definition image is provided. Image data encoded with a discrete cosine transform (DCT) is decoded using both an IDCT and an IDWT to generate IDCT processed image data and IDWT reduced image data. The IDCT processed image data and the IDWT reduced image data are combined to generate reduced image data that has a relatively lower definition than the image data and a relatively higher definition than the IDWT reduced image data.

Abstract: A TV GUI is provided to display a program guide that contains information on TV programming for a time period of predetermined duration. The program guide has a time scroll bar that enables a user to scroll a TV program schedule back and forward in time within the selected time period. When the user clicks on a MORE icon on the time scroll bar, the GUI switches into a "more times" mode to offer a menu of time options that represent various preselected time periods of TV programming. A time preset button may be provided on the program guide to enable users to review TV program information covering any preselected time period. A single click on the time preset button causes the GUI to switch to a program guide for the preselected time period.

Abstract: A TV graphical user interface (GUI) is provided to produce a multi-layered graphical presentation. The TV GUI operates in a channel changer mode to enable a user to tune to a required TV channel, and in a program guide mode to show TV program information. A memory for storing graphics data is capable of storing two graphics planes that represent upper and lower layers of graphics displayable on a TV screen. A graphics accelerator combines the graphics planes to produce various graphical effects on the screen. In the channel changer mode, the right hand side of the upper layer is made transparent to expose graphical buttons produced in the lower layer of graphics. In the program guide mode, the graphical buttons are partially covered by a program guide produced in the upper layer. When the user moves a cursor to the right hand side of the screen, the right hand portion of the program guide is made transparent to fully expose the graphical buttons in the lower layer.

Abstract: A TV graphical user interface (GUI) is provided in a satellite TV system to enable users to create customized channel lists. Everyday, favorite and theme lists may be generated to respectively combine TV channels being watched regularly, favorite TV channels and channels relating to particular subjects. In a regular channel changer mode, the TV GUI displays graphical channel changer composed of channel boxes that show numbers and logos of available TV channels. To create a customized channel list, the TV GUI is switched into a change list content mode, wherein a channel grid is displayed in addition to the channel changer. Using a "drag and drop" procedure, graphical boxes corresponding to selected channel boxes may be moved from the channel changer to cells of the channel grid, to create a customized list of TV channels or to add new channels to an existing list. TV channels may be removed from the list by moving boxes that represent unwanted channels from the grid and placing them outside the grid area.

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.
