Abstract

An electronic program guide flags episodes already watched in addition to making recommendations as to shows to watch in the future.

Description

EPG display of recommended shows with previously viewed shows identified
I. BACKGROUND OF THE INVENTION A. Field of the Invention
The invention relates to an Electronic Program Guide ("EPG") that also recommends programming to a user.
B. Related Art
EP 774866 shows an example of an EPG, in which a record is made of what programs have been viewed in order to help in making recommendations of similar programs with respect to future viewing.
II. SUMMARY OF THE INVENTION
It is an object of the invention to further improve upon electronic program guides.
This object is achieved by providing an indication that a piece of content has already been viewed. This indication is provided as an alert to the viewer, rather than as a tool in choosing future programs to recommend. Advantageously, an episode I.D. is used to assist in the flagging process.
Further objects and advantages will become apparent below.
III. BRIEF DESCRIPTION OF THE DRAWING
The invention will now be described by way of non-limiting example with reference to the following drawings.
Fig. 1 shows a system on which an EPG in accordance with the invention could operate. Fig. 2 is a flowchart relating to update of a profile.
Fig. 3 is a flowchart relating to operation of a recommender. IV. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The term "program" as used herein may relate to a single contiguous group of content of any type such as video, audio, or multimedia content, no matter what the vehicle of communication or distribution, such as TV or internet. The term "program" as used herein would include an episode or part of an episode and is to be distinguished from a series of programs, such as "Star Trek" or "Seinfeld" or "The Late Movie". The term "show" will be used synonymously with "program" herein. Thus, the marking of a program as watched as used herein is not the same as recording the fact that a viewer likes some series in general. The marking of a program as watched will not apply to the whole series, only to a particular piece of content. The term "EPG" will refer to an electronic guide to any type of "program" as that term is used herein.
In general terms like "view" or "viewer" when used herein are intended to include the possibility that the user is reading, listening to, or otherwise experiencing content of a program, even if there is no viewable content. Fig. 1 shows a system on which an EPG in accordance with the invention may operate. The system includes a display 101, a processor 102, a memory 103, a keyboard 104, a remote 105, and a network connection 106. The display may be any conventional display, such as a TV or computer monitor, and may be constructed from flat panel, CRT, or any other technology. The processor 102 may be disposed within a same housing as the display 101 , or external, and may be a general purpose processor such as would be found in a PC, or any other processor. Optionally, the processor 102 may be coupled to the display 101 via a network connection. The processor 102 may cause the display 101 to exhibit a graphical user interface ("GUI") or any other type of interface. The memory 103 may be of any type, such as magnetic, electronic, or optical, and may be disposed within the same housing as the display 101 and or the processor 102. Optionally, the memory may be coupled to the processor 102 via a network connection. There may be additional user input devices such as a mouse, joystick, or trackball. There may be additional user output devices, such as a printer 108 or loudspeaker 107, which may alternatively be connected via the display unit. Any of the connections shown may be wired or wireless. The user input devices, including 104 and 105 may alternatively be connected directly to the processor 102. The system of Fig. 1 may be a television set, with or without facilities for connection to the internet. The system of Fig. 1 may be a PC.
Fig. 2 shows a flowchart of a procedure for updating a user profile. This flowchart shows certain steps relevant to the invention. However, one of ordinary skill in the art may devise many other steps involved in updating a profile, not relevant to the invention, which are not shown here for brevity. This history retains data about programs a user has watched. At 201, a show enters the view history. This could happen either because the viewer has browsed though the show, or because the viewer has watched the show, or because the show has been recommended by the recommender, or because a user is entering data manually into the recommender. At 203, it is tested whether the show was actually viewed. This might involve applying some sort of threshold as to length of time the show was viewed ~ if the recommender is monitoring the viewer's use automatically — or inquiring of the user directly whether the user viewed the show. If the show was watched, an episode ID and a date for that show will be stored in the user profile. Episode I.D.'s are readily available, for instance in the EPG data provided by Tribune Media Services. The user profile is distinct from the view history in that the history is raw data, while the profile will have undergone some processing. For instance, the profile may have cumulative data. At 204, features relating to the show are added to the profile with a positive indication. If the show has not been viewed, features relating to the show will be added to the profile with a negative indication.
Building of a profile with features and negative and positive indications are shown in U.S. Patent Application Serial No. 09/498,271 filed 2/4/00 (US000018). However, the concept of marking a particular show as watched extends to other techniques of maintenance of a program guide or program recommender.
Fig. 3 shows a flowchart relating to operation of a recommender. The recommender operates on all shows during a given period. At 301 it is tested whether any further shows need a recommendation. If so, at 302 a recommendation relating to that show is computed. At 303, it is tested whether the episode ID of this show matches any in the profile. If so, the show is flagged as previously viewed at 304, then another show is retrieved for recommendation.
At 305, the show is added to the EPG. Typically the shows will be displayed in a grid or table like format with time of day along one axis and channel number along another axis, and each show will occupy a rectangle in the grid or table. Nevertheless, those of ordinary skill in the art may devise any number of other ways of displaying the EPG.
Recommendations relating to the show may be shown in color or numerical codes on a grid. The numerical codes may be in the form of percentages, with 100% being the highest possible recommendation. The indication of the fact that a show has been watched can also be a color or numerical code. Alternatively, the recommendations might be presented as a list of shows in order of desirability, with flags next to shows that have already been viewed. A show that has already been viewed might still be recommended if it fits well into the user's profile. Some users desire to experience the same content more than once, while other users do not. For instance, a show might be color coded as green, indicating a strong recommendation, with some shading bars or stippling overlaid to indicate that the show has already been watched. The term "color coding" as used herein shall include various types of shading, such as bars and stippling.
Alternatively, there may be an option to drop all shows that have already been viewed from the EPG output.
The recommendations may be presented on the display, printed out, broadcast on a loudspeaker, or communicated in any other suitable way.
From reading the present disclosure, other modifications will be apparent to persons skilled in the art. Such modifications may involve other features which are already known in the design, manufacture and use of EPG's and which may be used instead of or in addition to features already described herein. Although claims have been formulated in this application to particular combinations of features, it should be understood that the scope of the disclosure of the present application also includes any novel feature or novel combination of features disclosed herein either explicitly or implicitly or any generalization thereof, whether or not it mitigates any or all of the same technical problems as does the present invention. The applicants hereby give notice that new claims may be formulated to such features during the prosecution of the present application or any further application derived therefrom.
The word "comprising", "comprise", or "comprises" as used herein should not be viewed as excluding additional elements. The singular article "a" or "an" as used herein should not be viewed as excluding a plurality of elements.
