Definitions

  • the subject invention relates to recommenders for recommending programs for viewing by a user.
  • an explicit recommender a user explicitly inputs his/her preferences for different categories of content. For instance, he/she can indicate that he/she likes action movies very much by giving the genre "action move" a high score, and that he/she dislikes a particular channel by giving it a low (or negative) score. Then, for a new program, the scores of the categories are combined to determine a recommendation score.
  • an implicit recommender the user does not give the feature scores him/herself, but rather, a learning system is used that derives them from training examples (programs that the user has liked or disliked).
  • the main advantage of an explicit recommender is that the user is in full control.
  • the main advantage of an implicit recommender is that the system is easy to use. While an explicit recommender puts the user in full control, it is not particularly clear to the user how changing ratings for the different categories eventually affects which programs are recommended and which ones are not. For instance, if a certain TV show is not recommended, it is not clear which attributes should get a higher rating and how much higher it should be, in order for the show to become recommended.
  • This object is achieved in a method for controlling a program recommender, comprising the steps of: generating and storing profile parameters in various categories concerning a user's likes and dislikes in programming; calculating a rating for a selected program based on said profile parameters in said various categories; determining whether or not said selected program is recommended; calculating a threshold score in each of said various categories above which said selected program would be recommended; displaying whether or not said selected program is recommended, said profile parameters and said threshold scores; enabling said user to adjust at least one of said profile parameters with respect to a respective at least one of said threshold scores in order to change whether said selected program and other similar programs are or are not recommended; and recalculating said rating and said threshold scores in accordance with said at least one adjusted profile parameter.

  • the user is able to directly adjust the stored profile parameters in an intuitive manner such that the desired results are obtained, i.e., that a particular show and similar shows are or are not recommended.
  • said profile parameters and said threshold scores are displayed as respective icons on a bar chart-type graph, wherein the profile parameter icons are moveable by said user, the movement of the profile parameter icons representing new values for said profile parameters.
  • the user is able to directly affect the rating of a particular show and similar shows.

  • the television receiver 100 receives and displays television programs originating from a source.
  • an antenna 110 is shown as the source.
  • the television programs may originate from any of a plurality of sources, e.g., a set-top box, a DVD player, satellite, etc.
  • a tuner 120 is shown connected to the antenna 110 for tuning to a particular channel carrying a desired television program.
  • the tuner 120 supplies audio signals to an audio signal processor 130 which sends corresponding sound signals to a loudspeaker 140.
  • the tuner 120 supplies video signals to a video signal processor 150 which supplies corresponding display signals to a display 160.
  • a controller 170 controls the operation of the tuner 120 as well as the audio and video signal processors 130 and 150.
  • the controller 170 further provides control signals to an on-screen display (OSD) processor 180 which generates an OSD signal for displaying various graphical symbols on the display 160.
  • OSD on-screen display
  • This OSD signal is supplied to a video switch 190 along with the display signals from the video signal processor 150 for superimposing the graphical symbols onto the displayed images represented by the display signals.
  • the television receiver 100 further includes a television program recommender 200 for recommending television programs for the user.
  • the television program recommender 200 may be connected to a database containing information concerning television programs being transmitted or to be transmitted in the future. This is shown in Fig. 1 as a connection to the tuner 120 for receiving meta-data transmitted with the television signals in the form of, for example, an electronic programming guide (EPG).

In either case, the television program recommender 200 constructs profile parameters in various categories, and uses these profile parameters to calculate ratings for future television programs.
  • the television program recommender 200 is not infallible. There is always the occasion that a television program that the user desires to watch is not recommended, or that a television program the user does not desire to watch is recommended.

  • the television program recommender 200 is able to calculate a rating based on the user's profile parameters in various categories stored in the memory 204. If desired by the user, the television program recommender 200 generates a graphical display showing the program title, whether or not it is recommended for the user, as well as the profile parameters in a plurality of categories. As an example, Fig. 3A shows such a display for the movie "Terminator II", starring Arnold Schwarzenegger. Based on the profile parameters of the user, the television program recommender 200 does not recommend this movie for viewing by the user. However, suppose, for instance, that the user finds these types of movies desirable. The question now is how the user can modify the settings of the television program recommender 200 such that it will, in the future, recommend these types of movies.

  • Each of the icons 302-308 are movable by the user to any other position along its respective bar, using, for example, a cursor control (not shown). If the user desires such a movie, then the user selects one of the icons, for example, channel, and moves the profile parameter icon 302 such that it is co-located with the threshold target level 312, where the profile parameter icon is shown as 302' thereby indicating that the program is desired (recommended).
  • the television program recommender 200 then recalculates the remaining threshold levels 314-318 based on the user' s indicated desired rating, and moves the other threshold target levels (314', 316', 318') such that they are also co-located with the remaining profile parameter icons 304-308, as shown in. Fig. 3B.
  • the user may make partial adjustments to multiple profile parameter icons in two or more steps. For example, as shown in Fig. 3C, the user , increases the "channel" profile parameter icon 302 to a position 302' approximately halfway to the threshold target level 312. The television program recommender 200 then adjusts the levels of the remaining threshold target levels to 314', 316', 318'. Then, as shown in Fig.
  • the user may, for example, increase the rating of the "actor" profile parameter icon to 306' co-located with the modified threshold target level 316', and the television program recommender 200 adjusts the other threshold target levels to 312', 314" and 318" such that they are co-located with the profile parameter icons 302', 304 and 308 in the various categories.

  • the television program recommender 200 From a start 400, at step 402, the television program recommender 200 generates the profile parameters for the user based on either the user's past viewing habits or the user's responses to particular inquiries.

Abstract

La présente invention concerne un procédé et un agencement permettant de modifier les réglages d'un dispositif de recommandation de programmes de télévision (200) qui affiche une note (recommandé ou non recommandé) d'un programme de télévision sélectionné et qui affiche aussi des paramètres de profil de l'utilisateur dans un afficheur de type graphe en barres dans lequel la valeur des paramètres de profil de chacune des catégories sont montrées sous forme de position de l'icône de paramètre de profil (302-308), alors que le dispositif de recommandation de programmes de télévision montre aussi des icônes(312-318) représentant de niveau de seuil dans chaque catégorie au-dessus desquels le programme de télévision sélectionné serait recommandé. L'utilisateur peut changer les valeurs des paramètres de profil dans au moins une des catégories en déplaçant l'icône de paramètres de profil concernée (302-308) de sorte que, par exemple, elle atteigne ou dépasse l'icône de niveau de seuil respectif (312-318). Le dispositif de recommandation de programmes de télévision (200) recalcule ensuite la note et les niveaux de seuil afin qu'ils correspondent aux souhaits de l'utilisateur. Ainsi, l'utilisateur est à même de modifier les paramètres de profil du dispositif de recommandation de programmes de télévision (200) de sorte qu'il recommande ou ne recommande pas des programmes conformément aux souhaits de l'utilisateur.
