CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application No. 60/969,655 filed 3 Sep. 2007, which is incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The invention relates in general to systems and methods for discovery of content available for viewing in television (TV) systems, and in particular for quick navigation between content recommendation domains and recommendation sets therein using a single click action. 
       BACKGROUND OF THE INVENTION 
       [0003]    The control of TV content using a remote control user device (“remote controller”) in operative communication with the TV screen is known. As TV new services proliferate and become popular, more buttons are added to the remote controller to facilitate these new capabilities. On one band, the richness of these services (e.g. VOD, PVR, Games, User Generated Content, social network) is desired, as they attract new users and enhance the overall TV experience. On the other hand, this richness makes the remote control increasingly more complex to use, which in turn makes it increasingly less likely that large audiences can enjoy these new services. Therefore there is a need to keep developing and introducing new services while at the same time finding ways to simplify TV navigation with the remote controller. 
       SUMMARY OF THE INVENTION 
     Definitions 
       [0004]    Recommendation: Any entity (e.g. content, game, service, etc.) that is provided to a user, based on some or all of the following inputs: a user profile, the entity&#39;s metadata, external metadata and at least one algorithm that connects them. Exemplary recommendations include (but are not limited to): video content, live content, user generated content, games, time-shift TV content, TV recordings, new services, friends, groups based on shared interests and the like. 
         [0005]    Recommendation Domain: An aggregation of recommendations into a well defined category. Exemplary recommendation domains include broadcast, video on demand (VOD), user generated content (UGC), games, social based recommendations, external recommendations, recommendations by groups and experts, recommendations based on virtual identities and the like. Hereinafter, “recommendation domain” is referred to simply as “domain”. 
         [0006]    Recommendation set: The N out of M recommendations presented to a user in a given domain (N representing a subset of M and fulfilling N&lt;M). Exemplary recommendation sets include the entire list presented in the domain with reference to the N out of M recommendations. As used herein, the term “graphically presented” refers to the presentation, to a user, of at least one graphic image as opposed to the presentation of just text. 
         [0007]    In order to simplify navigation of TV content and overcome the increased complexity required from remote controllers, the invention provides a solution that includes mapping of several physical buttons on the remote controller to a single virtual representation button (also referred to as “icon”) on the TV screen. The icon is in essence a graphical representation of one or more remote buttons on the user device (referred to simply as “remote buttons”). The icon provides a “one click” function of “navigation” (selecting and changing recommendation domains and/or sets within the recommendation domains). Hence, although the user needs to interact with different physical remote buttons, the perception is of single on-screen button that changes in behavior according to single-click actions on the remote controller. This concept makes it easier to use and remember various services, as they seem to be controlled by a single virtual button. We note that “TV screen” is used herein. to represent any screen or display that can exhibit content or service, including (but not limited to) a mobile phone display and a computer display. Hereinafter, “icon” refers to any virtual representation button appearing on the TV screen in conjunction with the “one click” function as defined above. In some embodiments, the icon may have the shape of a compass. The compass shape of the icon is exemplary, and is in no way limiting. Other buttons or mechanisms that allow the “one click” navigation between domains and recommendation sets should be considered as covered by the invention (see e.g.  FIGS. 4-7 ). 
         [0008]    The invention provides a method for presentation and selection of content on a TV screen. In an embodiment, a remote controller is in operative communication with the TV screen. The remote controller uses customary buttons (such as “OK”, “UP”, DOWN” “LEFT” AND “RIGHT”) for navigation, as known in the art. The TV screen may exhibit a single domain, see  FIG. 1 , or may exhibit simultaneously two domains, see  FIG. 4 , each domain having its own recommendation set. One click changes are made between recommendation sets of a given domain, from a single domain to another single domain, or from a set of two domains to another set of two domains. Exemplarily (see  FIGS. 1-7 ), the OK remote button always changes recommendations sets and the DOWN button always changes a single domain to another single domain, or a two set domain to another two set domain. The exact settings of buttons (e.g. OK for recommendation sets and DOWN for domain changes) are provided in the configuration of the system. One can think of the OK button as a cyclic function that rotates recommendations sets in one or two domains and of the DOWN button as a cyclic function that changes domains. If for example there are ten domains, and two domains are presented on the screen each time, one will need 5 DOWN clicks to navigate through all ten domains. Note that in some embodiments, yet another button (e.g. LEFT) may be used to change a recommendation set of only one of two domains, leaving the recommendation set of the other domain unchanged. In some embodiments, a change of domains is typically accompanied by a change of the icon. The change of the icon helps the user to remember the presently shown domain. The user is then empowered so sift through a large amount of content (i.e. recommendation domains and recommendation sets) with the ease of a single-click. 
         [0009]    In examples shown in detail with reference to FIGS. l- 7 , the icon is used to change a recommendation set by pressing the OK button and to change a recommendation domain by pressing the DOWN button. Although a user clicks the OK remote controller button to navigate between recommendations sets and the DOWN button to switch domains, the user&#39;s perception is of a single button on the screen that reacts to “clicks” on the remote buttons while the action related to each remote button click is effected on the screen. In addition to changing recommendation sets, the click on the OK button may rotate the icon (e.g. a compass) while changing a recommendation set. Similarly, in addition to switching domains, the click on the DOWN button may change the shape of the icon from a compass to a circle. The changes in icon shape are also provided in the configuration. 
         [0010]    The icon may be activated by several mechanisms. For example, the operator may assign for its activation a shortcut button (e.g. the GREEN button on the user device) or it may be activated via some menu on the TV screen. The first domain activated by the shortcut button is the default domain (e.g. VOD) as configured by the vendor or operator. The default domain includes a default recommendation set. The user may now change the default recommendation set (or any currently displayed recommendation set) to another recommendation set in the same domain by a single click on one remote button (e.g. the OK button). The user may change any exhibited domain to another domain by a single click on another remote button (e.g. the DOWN button). The user may further access a particular recommendation of a set by using another remote button, e.g. the UP or LEFT button.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0019]    Throughout this application, a recommendation domain and/or recommendation set, alone or in combination, are also referred to as “content related entity” or simply “entity”. The numbering “first”, “second”, etc. as applied to recommendation sets define the status of these sets within a given domain and indicate that these sets differ from each other and include different recommendations. This is also reflected in the different numerals used to mark each set. Therefore, it is to be understood that a first recommendation set in a first domain is different from a first recommendation set in a second domain, a third domain, etc., and that a second recommendation set in a first domain is different from a second recommendation set in a second domain, in a third domain, etc. 
         [0020]      FIG. 1  shows a TV screen  100  with a graphic representation of an icon in the form of a compass button  102  and a first domain  104  (arranged horizontally) which includes a first recommendation set  106 . Domain  104  represents broadcast channels (a.k.a. live channels) and first recommendation set  106  includes recommendations BBC, National Geographic and NBC. Screen  100  may represent a default screen, in which case both domain  104  and recommendation set  106  represent default entities. The default screen is arrived at by pressing on a pre-determined button (e.g. GREEN) on the remote controller or by other means (e.g. a TV Menu). Recommendation set  106  is further connected to other inputs as described above e.g. the user&#39;s profile (“Yael”) as shown in this figure. 
         [0021]      FIG. 2  shows the result of a “one click” pressing on the OK button of a remote controller (not shown). This click causes the TV screen to change to a screen  200  which includes compass button  102  and first domain  104 , which now includes a second recommendation set  206 . As in  FIG. 1 , domain  104  represents broadcast channels. Recommendation set  206  includes the HBO, Fashion and the Movies channels. The click on the OK button changed the recommendation set in domain  104  from first recommendation set  106  to second recommendation set  206 , and also rotated the compass button by 90 degrees. 
         [0022]      FIG. 3  shows the result of another click on the DOWN button of the remote controller. This click causes the TV screen to change to a screen  300  (either from one of screens  100  or  200  or from a starting screen with a vertical default domain and recommendation set). Screen  300  includes a graphic representation of an icon in the form of a round button icon  302  with “Video on Demand” written therewithin and a second domain  304  (arranged vertically). Domain  304  represents VOD and includes a first recommendation set  306  with “most popular” recommendations. It should be noted that this does not limit us to show only “Most Popular” recommendations in this recommendations set (e.g. other types of recommendation like “user rating” could be part of the recommendation set). 
         [0023]      FIG. 4  shows the result of a click on the DOWN button of the remote controller when the TV screen is in a two domain mode (meaning the one-clicks are applied when a screen already includes two domains as shown). This click causes the TV screen to change to a screen  400 , which includes a third (horizontal) domain  404  with a first recommendation set  406  and a fourth (vertical) domain  408  with a first recommendation set  410 , as well as to exhibit an icon in the form of a round button  402 . Horizontal domain  404  represents “Friends” and vertical domain  408  represents “Applications”. Recommendation set  406  includes recommendations Movie Quiz, Dating and Chat (all applications related to “Friends”). 
         [0024]      FIG. 5  shows the result of another click on the DOWN button of the remote controller which changes the TV screen of  FIG. 4  to a screen  500 , in which the first recommendation set  406  of domain  404  of  FIG. 4  is changed to a second recommendation set  506 , which includes other applications related to “Friends”. Vertical domain  408  is unchanged from  FIG. 4 . The click on the DOWN button also rotated the icon  402  by  90  degrees relative to its position in  FIG. 4 . 
         [0025]      FIG. 6  shows the TV screen of  FIG. 5  as a screen  600 , wherein first recommendation set  410  of domain  408  in  FIG. 5  is changed to a second recommendation set  610  including recommendations Content, Share Photos and Send a Gift. Domain  404  and recommendation set  506  are unchanged from  FIG. 5 . This screen was arrived at by activation of icon  402  through again clicking on the OK button, which caused icon  402  to rotate by another 90 degrees. In this configuration, an even click of the OK button is used to change the recommendation set on the vertical domain whereas an odd click of the OK button changes the horizontal recommendation set belonging to the “Friends” domain. 
         [0026]      FIG. 7  shows a TV screen  700  with a graphic representation of an icon in the form of a round button  702 , which is different from both buttons  302  and  402 . The TV screen also includes a graphic representation of a fifth domain  704  with a first recommendation set  706  representing recommendation engines and a sixth domain  708  with a first recommendations set  710  representing genre top 10 lists. This screen was arrived at by clicking again on the DOWN button and activating again the icon. In this case, the change of the icon signifies the change in domains.
