"A METHOD AND AN ENTERTAINMENT SERVER SYSTEM"
INTEL CORPORATION, a Delaware corporation of 2200 Mission College Boulevard, Santa Clara, California 95052, United States of America,
The following specification particularly describes the invention and the manner in which it is to be performed:

METHOD AND APPARATUS FOR COLLECTING AND PROVIDING VIEWER
FEEDBACK TO A BROADCAST
BACKGROUND OF THE INVENTION Field of the Invention
The present invention pertains to the field of broadcast systems. More particularly, this invention relates to the art of collecting and providing viewer feedback to a broadcast. Background
The volume and variety of television, radio, and internet programming has increased considerably in recent years. For instance, digital cable systems and satellite antenna systems now offer hundreds of channels of programming twenty-four hours a day. Similarly, the internet provides access to countless on-fine interactive events. Even with a regular antenna, the airwaves in many markets are crammed full of dozens of television and radio channels. Sorting through all of the viewing, listening, and interactive '-options can.be time consuming-and frustrating. " -•"- -
A programming guide may be helpful, but most programming guides merely list broadcasts by lime slot and channel. Wilh hundreds of channels, including free channels, various categories of pay channels, pay per view channels, view on demand channels, etc., a programming guide can become very long and confusing. A viewer could spend a considerable amount of time reading a list of Broadcasts for a given time slot and deciphering which broadcasts are actually available to the viewer.
All too often, a viewer may simply choose.to flip through a few channels, or a great many- channels as the case may be, until he or she finds a broadcast that he or she can tolerate. When the viewer loses interest, he or she may flip through some more channels, aimlessly looking for something of interest. Meanwhile, advertisers, television producers, and other programming providers want their broadcasts to reach the most receptive audiences possible. A viewer with hundreds of channels to choose from, who aimlessly flips through channels, can easily miss an appealing broadcast or advertisement.

So, both viewers and programming providers want to be able to identify broadcasts that are likely to be of interest to particular viewers.
One way to predict how likely it is that a particular viewer will find a broadcast interesting is to examine feedback from previous viewers; especially previous viewers who have similar characteristics. Tor instance, if 85% of female viewers ages 25 to 35 highly recommend a broadcast, a significant portion of subsequent female viewers ages 25 to 35 are likely to enjoy the broadcast as well. For years, programming providers have used focus groups, surveys, Niclson ratings, etc. in an attempt to predict viewer preferences to make broadcasts appeal to the widest possible audience or to target certain audiences- These approaches have their limitations, however, for instance, (hey have done little to help viewers find the broadcasts that arc most likely to be interesting to them. Therefore, both viewers and programming providers need an improved method and apparatus to collect and provide viewer feedback to a broadcast based on viewer characteristics.
SUMMARY OF THE INVENTION
The present invention-provides an improved method and apparatus to collectandv,:
provide viewer feedback to broadcasts. According to one aspect of the present invention,
a rating is generated for a broadcast .by a server system. The rating is based at least in
part on viewer feedback to the broadcast,-and the rating indicates a likelihood of interest
in the broadcast for potential-subsequent viewers. Access to the rating is then provided
so that predications can be niade.as'to whether or no( the broadcast will be of interest to
potential subsequent viewers. -,•••••-. .
According to another aspect of the present invention, the rating is provided from the server system to an entertainment system, and the broadcast can be selected for. : viewing at the entertainment system based on the rating generated by the server system. In one embodiment, viewer the feedback is received at the entertainment system in response to a feedback questionnaire.

DETAILED DESCRIPTION
Figure 1 illustrates one embodiment of the present invention. The present invention collects viewer feedback to a broadcast and generates a rating for the broadcast based at least in part on the viewer feedback and, in certain embodiments, characteristics of the viewer. The rating indicates how likely it is that potential subsequent viewers will be interested in the same broadcast or other broadcasts in a series. Rating information can be collected from multiple viewers and made available to potential subsequent viewers. and programming providers. A broadcast may have several categorized ratings based on characteristics of the viewers. . For instance, in one embodiment, a broadcast rating may indicate that 93% of children ages 4 to 6 of the 5279 who responded enjoyed the broadcast and would like to see it again, 23% of adults ages 25 to 35 of the 2497 who responded enjoyed the broadcast and would recommend it for children, 6% of adults over
-3-

nge 75 of the 23S who responded enjoyed the broadcast and would recommend it for children, etc.
As discussed below in more detail, entertainment system 100 of Figure 1 represents a wide variety of audio, video, and interactive media systems. Under the control of system controller ! JO, entertainment system 100 collects viewer feedback from viewer 130 regarding a broadcast by providing questionnaire i 15 arid receiving viewer feedback 120. A broadcast may include a wide range of programming including a news segment, a situation comedy, a movie, a documentary, a commercial advertisement, nn on-line interactive event, etc.
Entertainment system 1 00 sends the viewer feedback to programming guide server. 170 over communications medium 150. Programming guide server ] 70 then generates a rating for the broadcast based at least in part on the feedback. The rating can also be based on feedback from additional viewers 180. The rating indicates a likelihood of interest in the broadcast for potential subsequent viewers. Ratings can be generated for multiple broadcasts and stored at programming guide server 170 where the ratings can be accessible to potential subsequent viewers and programming service providers 160 over communications medium 150.
Communications medium 150 represents a wide variety of media, including cable, optical fiber, satellite transmissions, telephone lines, radio frequency transmissions, and network communications such as over (he Internet. Communications can also be digital and/or analog.
Figure 2 demonstrates one embodiment of the present invention. First, in step 210, system controller 110 provides a feedback questionnaire to viewer 130. In one embodiment^ questionnaire 130 is provided at any time during or shortly after a broadcast at (he request of viewer 130. For instance, viewer 130 may have particularly enjoyed or hated a broadcast, so he or she may voluntarily take a moment to offer feedback. Alternately viewer 130 may be prompted to give feedback, so that viewer 130 can either give feedback or positively decline to give feedback.
In some embodiments, programming service providers 160 and/or programming
guide server 170 may offer incentives to viewer 130 lo encourage viewer 130 to give
.4-

feedback. For instance, the more feedback programming guide server ] 70 receives, the more accurate the ratings arc likely to be, and the more valuable the ratings are likely to be for programming service providers 160 and potential subsequent viewers. An incentive may be a small discounl on service charges for each feedback response. Alternately, locdback incentives may be provided for only certain broadcasts, depending on how much feedback is needed or wanted. For a new broadcast, the broadcast could be provided to a test audience to obtain ratings prior to wide distribution. In which case, feedback may be required of test audience viewers or additional incentives may be offered. •
In step 220, system controller 110 receives viewer feedback 120 in response to questionnaire 115. Questionnaire 1 15, and hence viewer feedback 320, can take several different forms, as discussed below with reference to Figures 4 and 6. For instance, questionnaire i 15 can be specifically designed to gather particular information about a broadcast, or it can be a single generic question, such as "Did you like this broadcast?"
In step 230, system controller 110 provides the feedback to programming guide server 170 over communications medium-150. As discussed below with reference to Figures 4 and 6, the characteristic information can also be gathered along with the feedback to the broadcast. For instance, specific questions can be added to questionnaire 115 to collect particular characteristic information.
In alternate embodiments, viewer characteristics can also be stored at system controller 110 or programming guide server 170. Various means could be used to automatically identify viewer 130, for instance, using face recognition software. Alternately, questionnaire 130 could prompt viewer 130 for a some form of viewer identification such as an identification number, and the identification number could be ... used to retrieve an anonymous viewer characteristic file. A viewer characteristic file could store in format ion. such as age, gender, marital status, family size, geographic location, education .level, income level, etc. Il could also store information thai may be useful to programming service providers 160, such as the hardware capabilities of entertainment system 100 and viewer 130's viewing habits, including channel preferences,
viewing duration, types of Internet web sites visited, etc. A viewer characteristics file
-5-

could also be updated over time as viewing habits change, the viewer grows older, component are added or deleted from entertainment system 100, a sport season beings and ends, etc. If a viewer's characteristics file were remotely accessible, the characteristic hie could be used for the viewer al any of a number of different entertainment systems, * ior instance, at the viewers home, work, neighbor's house, a hotel, etc.
In step 240, programming guide server ] 70 generates a rating of the broadcast based at least in part on viewer feedback 120. The rating can also be based on the characteristic information about the viewer. The ratings, as discussed below with reference to Figures 5 and 7, can be used in several different forms. For instance, separate ratings may be generated for different categories of viewers.
In step 250, programming guide server 170 provides the ratings to potential
subsequent viewers and programming providers 160. In one embodiment, ratings are
downloaded to potential subsequent viewers along with programming information. For
instance, one embodiment of programming guide server ] 70 provides programming guides
to viewers on a regular basis, and ratings for some or all of the programs are provided
along with we programmmgguMe^Jn. which case,, the .various, entertainment systems, ...r,.-:
used by potential subsequent viewers including viewer 130 and additional viewers 180,
may perform a variety of operations using the ratings information. Similarly, ratings
information can be downloaded to programming service providers 160 on a regular basis.
Programming service providers 160 may also perform a variety of operations using the
ratings information. '-'"'. :
In alternate embodiments, ratings information is stored centrally at programming
guide server 170. In which case, programming guide server J 70 performs various ;
operations using the ratings information and only provides the results of the operations. . to potential subsequent viewers and/or programming service providers 160. Ratings information may also be provided in real time. For instance, a viewer's screen may include a feedback meter that is repeatedly updated as ratings are generated from feedback provided by other viewers, for instance, in the viewer's community. In which case, the viewer could see how the other viewers are responding to a program as the viewer is
watching it.

Figure 3 demonstrates one embodiment of providing ratings to potential subsequent viewers. The method could be performed centrally by programming guide server 170 or locally by the various entertainment systems of potential subsequent viewers. In the illustrated embodiment, a potential viewer is consulting a programming guide provided by programming guide server 170. In step 310, viewer characteristic information is received. The viexvcr may provide this information in a number of different ways, including menu selections, voice commands, etc. Alternately, the information may be stored in a viewer characteristic file, stored locally or remotely. A viewer characteristic file may be selected automatically, based on face recognition for instance, or the viewer may be prompted to enter some form of identification. Viewer characteristic information may a]so be a combination of retrieved data and user provided daia. For instance, the viewer may be in the mood for a drama or a situation comedy. In which case, the viewer may input his or her preference, and a file may be retrieved that includes a iist of the viewer's favorite dramas and situation comedies, as well as other characteristic information.
Instep 320, the respective system controller or programming guide server 170 - -assembles a list of broadcasts based on a comparison of broadcast classification data and viewer characteristics. The broadcast classification data, as discussed below with reference to Figure 7, can include a channel and tirrie slot, a title, a synopsis, a parental guidance warning, etc. For instance, the characteristic information may include a list of programming sources or channels that arc available to the particular user at the particular entertainment system. In which case, the list of broadcasts may include only those broadcasts (I»at are available. Tor example, if a viewer's entertainment system does not receive satellite broadcasts, then satellite broadcasts can be left off the list.
Assembling the list.can be based on numerous additional characteristics. In one embodiment, a face recognition utility could be used to automatically retrieve viewer characteristic Files for a number of concurrent viewers and automatically cross-reference the characteristics. For instance, if children are among the viewers in the room, characteristic files for the children may instruct the system controller to lock out
broadcasts having adult content that would not be suitable for children.

In one embodiment, however, all broadcasts currently being aired, soon to be aired, currently available on pay per viewer view on demand, etc. are listed even if the viewer does not have access to all of the broadcasts. For instance, inaccessible broadcasts could be listed in a differeni type face than accessible broadcasts. In this situation, a viewer may be encouraged to purchase access to more programming sources in the future if the viewer knows what he or she is missing on those channels.
Then, in step 330, each broadcast in the list can be ranked according to viewer characteristics and ratings. The ratings categories can be very detailed. For instance, a category could be limited to viewers who characteristically enjoy (he same dramas and situation comedies as the potential viewer. The program with the highest rating in the category is ranked highest. Numerous additional viewer characteristics could also be used to identify which rating category to use. For instance, the rating categories could include viewers ages 45 to 55, viewers in metropolitan areas of Europe, viewers who play role-playing games on the Internet, etc. The possibilities for viewer characteristic categories arc virtually limitless.
. . . Viewer.characteristics for multiple simultaneous viewers can also be cross-referenced. Various aggregation techniques could be used to combine ratings. For instance, in one embodiment, if a viewer's characteristics match several ratings categories, the weighted average of the ratings could be used for a particular broadcast. In one example, viewer characteristics match three categories. In category A, 50% of the 500 responses were positive for the particular broadcast. In category B, 75% of the 2000 responses were positive. Jn category C, 90% of the 200 responses were positive. For this particular set of ratings categories, the weighted average for the broadcast is 71.481% positive.
Two simultaneous viewers, however, may have only categories A and C in common. In which case, the weighted average for both viewers together for the particular broadcast is 61.429% positive. If simultaneous viewers have no ratings categories in common, broadcasts could be ranked and listed separately for each viewer, or ranked separately but listed together in different type faces.

Once all the broadcasts have been ranked, the ranked list of broadcasts can be provided in step 340. The first broadcast on the list is intended to be the most likely broadcast that is of interest to the viewer. Thus, the viewer does not have lo sort through a vast array of programming choices.
Similarly, programming service providers 160 have more information lo predict which broadcasts will appeal to particular target audiences. In one embodiment, programming service providers 360 have access to anonymous viewer characteristic information. In which case, programming service providers can target advertise broadcasts directly to viewers for whom the broadcast ranks highly. For instance, when a viewer downloads a programming guide, the guide may include a tailor-made list of broadcasts that are likely to appeal to the specific viewer. Separate lists could be provided for each viewer who uses a particular entertainment system.
Figure 4 illustrates one embodiment of a questionnaire. In the illustralcd embodiment, the questionnaire is designed (o collect specific types of information regarding a news segment. Here, the news segment is part of a national address given by the President of the United States. In one embodiment, the questionnaire may be .. . automatically provided at the end of the broadcast to a test audience in order to prompt the test audience for feedback. Alternately, a viewer of the broadcast may volunteer to provide feedback. In which case, Ihe viewer may press a button on a remote control or a keyboard, or issue a voice command, which interrupts system controller 110..
In response, system controller 110 identifies the broadcast. In one embodiment, the broadcast currently being viewed is identified. Alternately, the broadcast can be identified by prompting the viewer lo identify Ihe broadcast from a list of recently viewed broadcasts. Then system controller 110 can access a storage medium lo retrieve a specific questionnaire, if one exists, or a generic questionnaire for the broadcast. The storage medium may store hundreds of questionnaires locally which were downloaded along with a programming guide from programming guide server 170. Alternately, system controller 110 may access programming guide server 170 to download questionnaires as requests for feedback are received.

In the illustrated embodiment, the specific questionnaire includes a broadcast synopsis so that the viewer can verify he or she is providing feedback to the correct broadcast. The questionnaire also includes questions for gathering characteristic inlormaiion in addition to feedback questions. Once ihc questionnaire is completed and s'lhmiucd, the information can be sent to programming guide server 170. Additional cimriiclcristic information may also be sent, for instance, from a viewer characteristics iiiC1. In certain embodiments, several responses may be stored for several broadcasts before being sent to programming guide server 170.
Figure 5 illustrates one embodiment of an output formal that may be used by a programming service provider. The ratings are categorized according to certain characteristics that are important to the programming provider. For instance, the results may help a politically motivated programming provider to decide whether or not to distribute the broadcast to a wider audience, and if so, to which audience the broadcast should be targeted based on viewer characteristics.
The feedback can also be used to make changes in (he presentation before the broadcast is aired again pr made.available to a wider audience. In one .embodiment, . .... feedback could be collected from viewers during a live presentation. In which case the ratings could be displayed to the presenter or the writer of the presentation in, for instance, a bar graph format so the ratings would be easy to read. Then, based on the feedback, the presenter or writer may choose to make mid-course content changes. Figure 6 illustrates one embodiment of a movie review questionnaire. The questionnaire includes title, genre, and synopsis information, all of which could be taken from a programming guide, and could be included in a generic movie review questionnaire. The illustrated questionnaire, however, includes specific questions for this particular movie. For instance, the programming providers want to know if viewers are interested in more movies about the same character, and different questions are posed to children . than parents.
Figure 7 illustrates one output format using the ratings generated from the questionnaire of Figure 6. At the top portion of the screen, a viewer indicates some
characteristics. Here, the viewer is interested in animated children's stories with some
- 10-

educational content. The viewer is 10 years old. Additional characteristic information may be supplied from a viewer characteristics file. The lower portion of the screen lists search results from among the broadcasts currently available. The list includes the title and synopsis of each broadcast as well as ratings information. Based on the characteristics of ihe viewer, the first broadcast in the list is intended to be the most likely to be interesting to the viewer.
In alternate embodiments, the questionnaire and output screens can be displayed in pop-up windows, full screen displays, side-bar displays, etc. The questionnaire and ^output screens may include many additional forms of broadcast classification data such as a broadcast identification number, the producer, the distributor, the length of the broadcast, a parental guidance warning, etc. The broadcast identification information may be downloaded with a programming guide or retrieved individually from programming guide server 170.

Except for the incorporated teachings of the present invention as described above, system controller 110 is intended to represent a broad category of computing devices known in the art. An example of such a computing device is a desktop computer system equipped with a high performance microprocessor(s), such as (lie Pentium® processor, Pcmium® Pro processor, or Pentium® II processor manufactured by and commonly available from Intel Corporation of Santa Clara, California. Another example of such a computing device is an Internet "appliance" device, such as a WebTV™ Internet Terminal available from Sony Electronics Inc. of Park Ridge, New Jersey, or Philips Consumer Electronics Company of Knoxvi'lc, Tennessee. It is to be appreciated that the housing size and design for system controller } 10 njay be alicrcd, allowing it lo better visually fil into system 300.
It is also to be appreciated that the several entertainment system components dcpiclcd in Figure 8 can be beneficially combined. By way of example, system controller 110 could be integrated into television/display device 802, DVD recorder/playback device S14, or audio/video tuner and amplifier 810.
Figure^9.:illuslrates one embodiment of a computing device suitable for use with the present inveiHibh.-According to one implementation, system controller 1*10 of Figure 1 is a computing device 900 of Figure 9. In the illustrated cmbodimenl.of Figure 9, device 900 includes processor 902 and cache memory 904 coupled to each other as shown. Additionally, device 900 includes high performance input/output (I/O) bus 9.06 and standard I/O bus 908, Host bridge 910 couples processor 902 to high performance I/O bus 906, whereas I/O bus bridge 912 couples the two buses 906 and 908 to each other. Coupled to bus 906 are network/ communication interface 924 and system memory 914. Coupled to bus 908 is mass storage 920, keyboard and pointing device 922, and I/O ports 926. Collectively, these elements are intended to represent a broad category of hardware systems, including but not limited to general purpose computer systems based on the Pentium® processor, Pentium® Pro processor, or Pentium® II processor, manufactured by Intel Corporation of Santa Clara, California.
In one embodiment, various electronic devices are also coupled lo high
performance I/O bus 906. As illustrated, analog tuner/digital satellite/cable devices 928,
- 14-

are also coupled to high performance 1/0 bus 906 to allow device 900 to "tune" to various programming input channels.
These elements 902 - 928 perform their conventional functions known in the art. In particular, network/communication interface 924 is used to provide communication between device 900 and any of a wide range of conventionaf networks, such as an Ethernet, token ring, the Internet, etc. It is to be appreciated that the circuitry of interface 924 is dependent on the type of network the device 900 is being coupled to.
Mass storage 920 is used to provide permanent storage for the data and programming instructions to implement the above described functions, whereas system memory 914 is used to provide temporary storage for the data and programming instructions when executed by processor 902. I/O ports 926 are one or more serial and/or parallel communication ports used to provide communication between additional peripheral devices which may be coupled to device 900.
It is to be appreciated that various components of device 900 may be re-arranged. For example, cache 904 may be on-chip with processor 902. Alternatively, cache 904 .and processor 902 may be packaged together as a "processor module", with processor 902 being referred .to as the "processor core". Furthermore, certain implementations of. the present invention may not require nor include all of the above components. For example, mass storage 920, keyboard and pointing device 922, and/or network/communication interface 924 may not be included in device 900. Additionally, the peripheral devices shown coupled to standard I/O bus 908 may be coupled to high " performance 1/0 bus 906; in addition, in some implementations only a single bus may exist with the components of device 900 being coupled to the single bus. Furthermore, additional components may be included in device 900, such as additional processors, storage devices, buses, or memories.
In one embodiment, the present invention is implemented as a series of software routines run by device 900 of Figure 9. These software routines comprise a plurality or series of instructions to be executed by a processor in a hardware system, such as processor 902 of Figure 9. Initially, the series of instructions are stored on a storage
device, such as mass storage 920. It is to be appreciated that the series of instructions
- 15-

can be stored using any conventional storage medium, such as a diskette, CD-ROM, magnetic tape, DVD, laser disk, ROM, Flash memory, etc. It is also to be appreciated that (he scries of instructions need not be stored locally, and could be received from a remote storage device, such as a server on a network, via network/communication interface 924. The instructions arc copied from the storage device, such as mass storage 920, into memory 914 and then accessed and executed by processor 902. In one implementation, these software routines arc written in the C++ programming language. It is to be appreciated, however, (hat these routines msy be implemented in any of a wide variety of programming languages.
In alternate embodiments, the present invention is implemented in discrete hardware or firmware. For example, one or more application specific integrated circuits (ASICs) could be programmed the functions of the present invention. By way of another example, the present invention can be implemented in one or more ASICs of an additional circuit board for insertion into hardware system 900 of Figure 9.
In one embodiment, hardware system 900 includes control circuitry to retrieve a questionnaire from system memory 914, mass storage 920, or programming guide server 170 over network/communication interface 924. Processor 902 or some other form of hardware device like a digital signal processor (DSP) or one or more ASICs may comprise the control circuitry.
