Title: Guide display for antenna direction

Description:
FIELD 
     The present invention relates generally to televisions and, more particularly, to systems and methods for altering the direction of an antenna for viewing available broadcast stations. 
     BACKGROUND 
     Prior to the advent of broadcasting television signals via cable and satellite, terrestrial broadcasting systems broadcast television signals which were received by a viewer via an antenna. These system were analog systems which had physical channel numbers. To view the broadcast of a particular broadcast station, the viewer would change the channel selector of the television to the physical channel corresponding to the broadcast station and then adjust the antenna direction for best reception. 
     Terrestrial broadcasting of television signals is changing to digital. In order to receive the broadcasting signal, the viewer needs to set an antenna direction toward the broadcasting station. Since digital broadcasting systems have virtual channels, the consumer cannot select a physical channel to receive the digital broadcast signal and get virtual channel information from the broadcasting station. Instead the consumer needs to set the antenna direction first before tuning the television to the desired channel. 
     Therefore, it would be desirable to provide systems and methods that facilitate orienting the direction of an antenna for viewing television signals from available broadcast stations. 
     SUMMARY 
     Embodiments described herein are directed to improved methods and systems that facilitate orienting the direction of an antenna for viewing television signals from available broadcast stations. In a preferred embodiment, an antenna directional guide is displayable to the viewer on a screen of a television to which the antenna is connected enabling the viewer to select an antenna direction to view television signals receivable by the antenna from broadcast stations located along selected reception direction of the antenna. 
     Other objects, systems, methods, features, and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of this invention, and be protected by the accompanying claims.

     DETAILED DESCRIPTION 
     Embodiments described herein are directed to improved methods and systems that facilitate orientation of the direction of an antenna for viewing television signals from available broadcast stations. In a preferred embodiment, an antenna directional guide is displayable to the viewer on a screen of a television to which the antenna is connected enabling the viewer to select an antenna direction to view television signals receivable by the antenna from broadcast stations located along selected reception direction of the antenna. 
     Turning to figures, the embodiments provided herein are described in detail. In an embodiment, as depicted in  FIG. 1 , a television system  100  adapted to enable viewing of terrestrial broadcasts of digital television program signals comprises a central processing unit (CPU)  102  coupled to an audio-video output unit  108 , a remote signal receiver  114 , which is operably coupled to a remote control unit  116 , and an antenna unit  120 . The CPU  102  preferably comprises non-volatile memory  106  coupled to a logic unit  104  which includes integrated circuits, processors, and software stored in memory  106  and executable on the processors. The logic unit  104  is configured to receive program signals S p , including audio such as radio program signals and audio-video signals such as television program signals, from an antenna  122  of the antenna unit  120 , and output the program signals to an audio-video output unit  108 . The antenna unit  120  includes a directional controller  124  for orienting the antenna  122  to a desired receiving direction to receive digital terrestrial broadcast signals from broadcasting station along the receiving direction. 
     The audio-video output unit  108  preferably includes a video display  110  for displaying the images or video component of the program signal S p  and a speaker  112  for outputting the audio program signal S p  or the audio component of the program signal S p  associated with the video component of program signal S p . 
     The logic unit  104  is also configured to display an antenna directional guide  200 , as shown in  FIG. 2 , on the video display  110  of the television  100  to inform the viewer of the directional locations of available broadcasting stations and determine the correct or desired direction of the antenna  122  to receive a desired broadcasting station. The antenna directional guide  200  can be accessed through a menu system of the logic unit  104  or via a dedicated key on the remote control unit  116 . 
     Stored in the memory  106  of the television  100  is map information regarding broadcasting stations. The logic unit  104  is configured to display a map  210  corresponding to a viewer&#39;s location  214  defined by a zip code, street address, map coordinates, GPS location, and the like, and a table  220  having a first column  222  corresponding to a direction of the antenna and a second column  224  listing broadcast channels corresponding to broadcasting stations available along the reception direction, e.g., antenna directions A, B and C, of the antenna  122 . The map  210  includes street or roadway representations  212  and a compass arrow  213  designating the north N direction. Upon accessing the antenna directional guide  200  a first time, the viewer is prompted to enter the viewer&#39;s geographical location. 
     In one embodiment, the antenna directions A, B, C and the like, can be predetermined directions determined by the logic unit  104  based on a viewer&#39;s location  214  and available broadcasting stations in the geographical area corresponding to the viewer&#39;s geographical location  214 . The viewer is prompted to choose a antenna direction from the list of directions  222  in the table  220 . Upon receipt of the selected direction, the logic unit  104  instructs the directional controller  124  of the antenna unit  120  to orient the antenna  122  in the desired direction. 
     In another embodiment, the viewer can step through antenna directions using the cursor on the remote control unit  116 . The antenna directions through which the viewer steps correspond to degrees on a compass with north N being at 0° and 360°. The step increments can be in single or multiple degrees. As the viewer steps through antenna directions, the available broadcast channels corresponding to the antenna direction are determined by the logic unit  104  and displayed to the viewer on the video display. Upon receipt of the selected direction, the logic unit  104  instructs the directional controller  124  of the antenna unit  120  to orient the antenna  122  in the desired direction. 
     When the viewer selects a preferred antenna direction, the selected direction and corresponding available broadcast channels are stored in memory  106 . When the viewer accesses the antenna directional guide  200 , the save antenna directions can be displayed in the antenna direction table  220 . The viewer can then be prompted to choose a saved antenna direction in the table  220  or find a new antenna direction by stepping the through antenna directions using the cursor on the remote control unit  116 . 
     The particular examples set forth herein are instructional and should not be interpreted as limitations on the applications to which those of ordinary skill are able to apply the systems and methods described herein. Modifications and other uses are available to those skilled in the art which are encompassed within the spirit of the invention as defined by the scope of the appended claims.
