Abstract
A method and apparatus providing for expanded search functionality in an electronic program guide (EPG) for television is described. The expanded search function finds show titles that are the same or similar to the show title of the program data currently displayed by the EPG. The expanded search function also finds shows similar to the one currently displayed by the EPG by using additional search elements based on the descriptive part of the EPG program data, such as actors, director, genre, etc., as well as search parameters based on the show time, channel, etc. Rather than only finding exact matches, the expanded search function uses fuzzy logic to find near matches and prioritizes the results according to the search elements and parameters as specified by the viewer.
Description
- This application is a continuation of application Ser. No. 09/752,612, filed Dec. 29, 2000, now U.S. Pat. No. 7,213,256, which claimed the benefit of provisional application No. 60/202,303, filed May 5, 2000, the disclosures of each of which are hereby incorporated herein.
- 1. Field of the Invention
- The present invention relates generally to electronic programming guides for television. In particular, the present invention relates to providing a method for searching for the same or a similar show using an interactive electronic program guide.
- 2. Description of Related Art
- Electronic programming guides (EPG) are known in the art and provide television viewers with on-screen television schedule information. Widely used are the on-screen program schedules that are continuously transmitted over a dedicated viewing channel, such as those available on community antenna television (CATV), closed circuit television (CCTV), and other types of signal distribution systems (e.g. hotel television systems, pay-per-view systems, etc.). These guides display the available programs on the television screen in a continuously scrolling grid, typically with the rows representing channels and the columns representing show times.
- An advantage to the dedicated channel electronic program guides is that they are centrally maintained and distributed. However, they provide little or no viewer control, and are limited in the amount of program information that can be displayed. They often require patience while waiting for the desired channel listings to scroll into view, as well as periodically returning to the dedicated channel in order to view later time slots that were not previously displayed.
- More sophisticated electronic program guides that allow the viewer to interact with and control the display are also known in the art. Typically, the interactive electronic program guides display digitized program data on the television screen in a grid similar to that used in the dedicated channel guides. But instead of displaying a continuously scrolling grid transmitted over a dedicated channel by a centralized source, the digitized program data is captured from a broadcast signal or periodically downloaded into the viewer's home receiving device, such as a cable set-top box, television, or VCR, where it is stored in the receiving device's memory. The receiving device is equipped with a processor that dynamically generates a displayable electronic program guide from the program data in response to video control commands entered by the viewer, usually with a television remote control unit.
- Some EPGs now available to television viewers provide an opportunity to search the program data to find additional instances of the same show. For example, if a viewer tunes into a show toward its end and wants to see when the show will air again, possibly on the same channel, the EPG may allow the viewer to list all the instances of the show with their show times and stations.
- However, since the EPG can search the program data for only exactly the same show demonstrates certain limitations. First, listings of even the same show may differ slightly among different stations. For example, there may be certain differences in the name or title of the show. This is primarily because the number of characters allowed in most EPGs is very limited, thereby requiring most show titles to be abbreviated. Since different program data providers may choose different abbreviations for the same show, not all instances of the same show may be found by using the name or title of the show. Second, if a viewer tunes into the last broadcast of a particular show, a search of the program data would not help because it cannot find any future showings of that particular show.
- What is needed, therefore, is a way to search for shows with increased functionality.
- A method and apparatus providing for expanded search functionality in an electronic program guide (EPG) for television is described. The expanded search function finds show titles that are the same or similar to the show title of the program data currently displayed by the EPG. The expanded search function also finds shows similar to the one currently displayed by the EPG by using additional search elements based on the descriptive part of the EPG program data, such as actors, director, genre, etc., as well as search parameters based on the show time, channel, etc. Rather than only finding exact matches, the expanded search function uses fuzzy logic to find near matches and prioritizes the results according to the search elements and parameters as specified by the viewer.
- The present invention will be described by way of exemplary embodiments, but not limitations, illustrated in the accompanying drawings in which like references denote similar elements, and in which:
-
FIGS. 1 a-1 c illustrate a prior art electronic program guide display with a search function and search function result; -
FIG. 2 illustrates an electronic program guide display with an expanded search function result in accordance with one embodiment of the present invention; and -
FIGS. 3 a-3 c illustrate a electronic program guide display with an expanded search function and search function result in accordance with one embodiment of the present invention. -
FIG. 4 is a block diagram overview of an EPG on which one embodiment of the invention may be implemented. -
FIGS. 1 a-1 c illustrate a prior art electronic program guide display with a search function and search function result.FIG. 1 a illustrates a priorart EPG display 100 that contains an example of a show listing from a selection by the viewer with a few shows appearing, such as Cheers, Frasier, Friends, M.A.S.H, and Touched by an Angel.FIG. 1 b illustrates the same priorart EPG display 110 in which the viewer has marked one of the shows, in this case Touched by an Angel 111 broadcast on ABC at 8:00 pm, in preparation for actuating asearch function 105 for other instances of the Touched by an Angel show. Note, however, that the show title displayed in the prior art EPG displays 100/110 has been abbreviated to “Touch by an Ang.” The priorart search function 105 performs a simple and straightforward search for shows matching the abbreviated show title “Touch by an Ang” and the search results are illustrated in theEPG display 120 inFIG. 1 c. As shown inFIG. 1 c, besides the originally displayed instance of Touched by an Angel 111 broadcast on ABC at 8:00 pm, only one other instance of the show title “Touch by an Ang” 121 broadcast on channel UPN at 9:00 pm is found and displayed inEPG display 120. -
FIG. 2 illustrates an electronicprogram guide display 200 with an expanded search function result in accordance with one embodiment of the present invention. In the illustrated embodiment the viewer has marked one of the shows, in this case Touched by an Angel 111 broadcast on ABC at 8:00 pm, in preparation for actuating a search function for other instances of the Touched by an Angel show, the same as in the example illustrated inFIGS. 1 a-1 b. Instead of searching for a show with the exact same title, an embodiment of the expanded search function of the present invention searches for shows with titles that are similar to the abbreviated title “Touch by an Ang” to find not only the first instance found by the prior art search broadcast on UPN and 9:00pm 121, but also a second instance broadcast on PAX at 11:00pm 201. As can be seen, the show title of thesecond instance 201 is not abbreviated, but rather spelled out fully, which prevented the prior art search from finding the show. -
FIGS. 3 a-3 c illustrate a EPG display with an expanded search function and search function result in accordance with one embodiment of the present invention.FIG. 3 a illustrates a priorart EPG display 300 that contains an example of a show listing from a selection by the viewer with a few shows appearing, such as Cheers, Frasier, Friends, M.A.S.H, and Touched by an Angel, similar to that illustrated inFIG. 1 a.FIG. 3 a further illustrates theEPG display 300 in which the viewer has marked one of the shows, in this case Cheers 301 broadcast on ABC at 8:00 pm, in preparation for actuating an expandedsearch function 305, either through a viewer action on the display as illustrated (e.g. clicking the desired show with an input device and displaying the clicked show as highlighted in contrast to other shows) or through a viewer action on a remote control device. In one embodiment a command button or other graphical visual icon is provided for affirmatively entering a command on the EPG display to initiate the expandedsearch function 305 based on the marked selection of the Cheers 301 show. - With reference to
FIG. 3 b, upon selection by the viewer, the expandedsearch function 305 first moves or pastes into theEPG search display 310 the marked/selected show name Cheers 301 and its associated features, such as the name orshow title 302,directors 303,actors 304, etc., as drawn from the descriptive part of the EPG program data. The associated features operate as search elements in addition to or in lieu of the show title search on the show name Cheers 301. - In one embodiment, the search screen may have additional search parameters such as
genre 306, show date ortime ranges 307, or other parameters that indicate further viewer preferences. Like the search elements, the additional search parameters may also be derived from the descriptive part of the EPG program data, e.g. agenre 306 of comedy or drama. The parameters may also be based on the scheduling part of the EPG program data, e.g. the show date ortime ranges 307 or the show broadcast channel (not shown). When the viewer actuates the expandedsearch function 305, either through a viewer action on the display as illustrated or through a viewer action on a remote control device, a search is performed that has a broader scope than theprior art search 105 which only searches for additional broadcasts of exactly the same show. - In one embodiment a command button or other graphical visual icon is again provided for affirmatively entering a command to further carry out the expanded
search function 305 based on the selection of theCheers 301 show and the selected search element(s) or parameter(s). In the illustrated example inFIG. 3 b, thesearch element actors 304 is selected, so the expandedsearch function 305 will search for all shows having the same actors that were listed in the descriptive program data for theselected Cheers show 301, but will not confine the search to only shows having the “Cheers” show name. - The results of the expanded
search function 305 are illustrated inEPG display 320 inFIG. 3 c. As shown, the results include not only the two instances of shows having the “Cheers”show name actor Kelsey Grammar 313, and the Becker show withactor Ted Danson 314. Thus, the results are characterized by thesearch element actors 304, the values for which are derived from the selected show, in thiscase Cheers 301, that forms the basis of the search reference. The viewer can then select from the results which of the shows to watch, or may repeat the expandedsearch function 305 using the selected result as the specific show that forms the basis of the search reference. - It should be understood that the same technique may also be used with movies or any other program for which the show title and other descriptive information are available on the EPG program data. For example, if a Steve Martin festival is playing, a viewer could search for other shows in which Steve Martin appears instead of only the specific show that forms the basis of the search reference.
- It should further be understood that the EPG displays 200, 300, 310, 320, as shown are for descriptive purposes only, and that other variations for accomplishing the described entry, selections or commands to the EPG displays 200, 300, 310, 320 may be employed without departing from the principles of or exceeding the scope of the present invention.
- In one embodiment, the sort order of the results in
EPG display 320 is determined by the selection of additional search parameters. Many different additional parameters may be set, such as the show times, the likelihood of matching content based on the search elements from the program descriptive data (i.e. the actors, directors, etc.) Rather than attempting an exact match, this type of approach uses a kind of “fuzzy logic” database search, where the probability of a match is determined according to the rules established by the search elements and parameters, and the results are presented in a list according to the probability of a near match, with the highest probability on the top and the lowest probability on the bottom. - In one embodiment, the viewer can fine tune the search, if desired, by changing some existing parameters or by editing the show name in
EPG display 310. An advantage of the expandedsearch function 305 is that it offers a much higher level of viewer interaction with the EPG. The expandedsearch function 305 allows the viewer to effectively search for “replacements” of the show if the show itself is not available, or if a replacement, for example, has an earlier re-airing time than the show originally specified. In one embodiment, the exact or nearest matches may not be at the top of the list, but rather further down, depending on the search parameters specified by the viewer. - In one embodiment the search elements and parameters may be combined for a complex search that may be further adjusted by a slider or other or other graphical visual icon or input device which permits the viewer to give additional weight to certain parameters, such as the actor's name versus the director's name, or the show genre versus the actor's name. In one embodiment the use of the slider or other graphical visual icon or input device causes the input of a discrete value into the fuzzy logic of the expanded search function's search engine, so that the search is weighted in favor of one search element or parameter over another, instead of merely a simple search, as in the prior art EPGs (e.g. search by name or not name). In one embodiment, the discrete value is selected from a range of discrete values displayed as a continuum on the
EPG display 310. In alternate embodiments, the discrete value may be specified using a keypad on a remote control device or some other conventional mechanism for specifying a value. -
FIG. 4 provides a block diagram overview of anEPG system 400 on which an embodiment of the present invention may be implemented. Aprocessor 410 is coupled in communication with an EPGprogram data database 420, aprogram logic memory 440, avideo input source 430, avideo output 450 and an EPGdisplay user interface 460. - The
processor 410 may be any of a plurality of commercially available processors such as the a processor from the Motorola 68000 series of processors, a processor from the Intel 8086 family of processors or a higher level processor such as a processor from the Intel Pentium™ family of processors or from the Motorola PowerPC™ family of processors. Theprocessor 410 in the described embodiment acts under program control by a program stored inprogram logic memory 440 to perform the previously described expanded search functions 305. - The
program data database 420 is populated with program data obtained from a commercial EPG program data source such as the TVGuide, or other providers via a machine-accessible medium, including a CD or floppy diskette, or via the Internet or any communication medium, including a satellite, conventional or cellular telephone network. Theprogram data database 420 may reside locally with theprocessor 410 or remotely on a centralized server accessible via the Internet or other communication network. In one embodiment theprogram data database 420 may reside inprogram logic memory 440 or on a removable storage medium accessible by theprocessor 410. The EPG program data on theprogram data database 420 is comprised of show names or titles, and other descriptive information such as the actors, director, or genre. The EPG program data is further comprised of scheduling information such as the channels, dates, and times of broadcast. The descriptive information and scheduling information are used to provide the search elements and search parameters previously described and used by the expandedsearch function 305. - The EPG
display user interface 460 comprises, among other displays, the previously described EPG displays 200, 310, 320, and 330 that provide for user input to the expandedsearch function 305 through a viewer action on the EPG displays as previously described or through a viewer action on an input control device. The program stored inprogram logic memory 440 performs the expanded search functions 305 in conjunction with the user input via the EPGdisplay user interface 460 to find and display the results of the search, and in some embodiments to further control the selection of programs from thevideo input 430 for display on thevideo output 450. It should be noted that although the EPGdisplay user interface 460 is typically implemented in anEPG system 400 that is part of a television set, video recording device, or television-enabled appliance, the EPGdisplay user interface 460 may also be implemented separately on a browser as one or more web pages that display information from theprogram data database 420 and made available over the Internet without departing from the principles of the invention. - Accordingly, a novel method and apparatus is described for a electronic asset lending library method and apparatus, so as to enable the electronic management and redistribution of licenses for electronic assets installed on computers connected through a communications network.
- From the foregoing description, those skilled in the art will recognize that many other variations of the present invention are possible. In particular, while the present invention has been described as being implemented on
system components search function 305, may be distributed in other components of aEPG system 400. Thus, the present invention is not limited by the details described. Instead, the present invention can be practiced with modifications and alterations within the spirit and scope of the appended claims.
