## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 09/823,588, filed Mar. 30, 2001, which claims the benefit of U.S. Provisional Patent Application No. 60/193,948, filed Mar. 31, 2000, which are hereby incorporated by reference herein in their entireties.


BACKGROUND OF THE INVENTION
This invention relates to advertisement delivery systems and methods. More particularly, this invention relates to systems and methods that associate advertisements with other media using metadata links.
With the advent of modern television equipment and communication networks, advertisers have been able to provide graphical advertisements to viewers such as ordinary television commercials. However, in the past, these systems were limited in their functional capabilities and typically only provided non-content or semi-content related advertisements to viewers.
To increase the effectiveness of advertisements, it may be advantageous to both advertisers and consumers alike to associate what is being advertised with other media (e.g., programs, applications, etc) that are provided to viewers. Associating these advertisements with other media may not only tend to increase the effectiveness of the advertisements, but doing so may also provide users with an increased awareness of the content of such other media, as opposed to simply being subject to an advertisement for a product or service without being provided additional information.
It is, therefore, an object of the invention to provide systems and methods for associating advertisements with other media using metadata.
SUMMARY OF THE INVENTION
In accordance with this and other objects of the present invention, systems and methods for associating advertisements with other media are provided. These systems and methods may associate advertisements with other media by using an enhanced data set herein referred to as “metadata”. For example, metadata is data that may be used to describe programming and may include any information that may be associated with a program and/or that may describe the program, its content, or services related to the program.
One aspect of the present invention may include advertisements that are targeted to other media based on metadata contained within such other media. For example, metadata may be provided at the scene level of a program. By providing metadata at the scene level, more descriptive information about a program or other media can be provided in a more temporally associated way.
Another aspect of the invention may include advertisements that are provided within display screens of guidance applications based on metadata of other media attached to or associated with the guidance application. For example, in an interactive program guide, advertisements may be presented in a browse overlay and such advertisements may be based on metadata associated with a currently selected program listing. In addition, the interactive program guide may present advertisements in a menu or guide overlay based upon the metadata associated with the last program viewed.
A further aspect of the invention may include metadata that contains a source reference for an advertisement. The source reference may be, for example, a Uniform Resource Locator (URL). This source reference may be recorded or otherwise stored by a guidance application. For example, on playback of the recorded program, the guidance application may play back advertisements from a location defined by the source.
Still a further aspect of the invention may include enabling a system provider to manage advertisement inventories and to provide marketing and other data to advertisers. For example, through polling, monitoring user requests, or using any other scheme suitable to the chosen implementation of the system, a system provider may track valuable marketing information and provide such information to advertisers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention provides systems and methods for associating advertisements with other media (e.g., programs, applications, etc).
These systems and methods may associate advertisements with other media by using an enhanced data set herein referred to as “metadata”. Metadata may be used to describe programming and may include any information that may be associated with a program and/or that may describe a program, its content, or services related to a program. Metadata may describe, for example, the content of a program, whether commercials may be skipped during playback of a recorded program, or the clothes that an actor is wearing.
Metadata may be transmitted and/or received by a user's equipment (e.g. a set-top box) through any communications network (e.g., cable systems, satellite systems, modems, wireless paging frequencies, the Internet, etc., or any combination thereof). Furthermore, metadata may be transmitted and/or received by the user's equipment on one or more broadcast channels. For example, a program may be received on a program channel, and metadata for that program may be received through this program channel's vertical blanking interval (VBI). Additionally, metadata may be provided by utilizing other existing analog and digital technologies such as the “Advanced Television Enhancement Forum” (ATVEF) protocol for enhanced television programming.
One aspect of the present invention may include advertisements that are targeted to other media based on the metadata contained within such other media. For example, metadata may be provided at the scene level of a program. Each scene of the program may show a different product. In one scene, an actor may be driving a certain car or wearing a particular type of clothing. In another scene, the actor may be wearing different clothing, or another actor may be in the shot with other items that may be promoted (e.g., a cell phone, sun glasses, etc). As stated above, these products may be linked to advertisements for these products using metadata. By providing metadata at the scene level, more descriptive information about a program or other media can be provided in a more temporally associated way. In this way, the advertising of a product is enhanced because the viewer can watch the product or service as it is worn, used, or provided.
Another aspect of the invention may include advertisements that are provided within the display screens of guidance applications based on metadata of other media attached to or associated with the guidance application. For example, in an interactive program guide, advertisements may be presented in a browse overlay and such advertisements may be based on metadata associated with a currently selected program listing. The metadata for a program listing may include any descriptive information about the program itself, the channel the program is being displayed on, and/or any other information attached to or associated with the program listing.
Another aspect of the invention may include metadata that contains a source reference for an advertisement. The source reference may be, for example, a Uniform Resource Locator (URL). For example, when a program. is recorded, the metadata along with the source reference may be recorded or otherwise stored by a guidance application. On playback of the recorded program, the guidance application may play back advertisements from a source as defined, for example, using a URL contained in the recorded program. A system provider may then replace previously stored and now outdated advertisements with new ones having the same identifier. Therefore, for example, when a program is recorded and subsequently played back, new advertisements may be retrieved and presented simply by changing an advertisement's identifier.
Another aspect of the invention may include enabling a system provider to manage advertisement inventories and provide marketing and other data to advertisers. The system provider may manage advertisement inventories by providing fresh advertisements, as described above. By providing fresh advertisements, the System provider controls what advertisements the viewer sees when playing back a recorded program. By controlling which advertisement a viewer sees on playback, the system provider may be able to sell playback advertising space to advertisers.
Furthermore, system providers may provide advertisers valuable marketing information and other data. Through polling, monitoring user requests, or using any other scheme suitable to the chosen implementation of the system, a system provider may track valuable marketing information and provide such information to advertisers. Marketing information may include the program recorded, the number of times an advertisement is accessed, the time at which the advertisement was accessed, etc., and may also include demographic information associated with a user's account.
In one embodiment of the invention, a system may include: one or more receivers that may receive signals and/or data; one or more transmitters that may transmit signals and/or data; a processor that accepts a user's input signal, that selects an object within the visual plane of a video display, that reads metadata, that selects an advertisement, and that causes the advertisement to be displayed; and one or more storage devices capable of electronically storing signals and/or data.
In another embodiment of the invention, a system may include a processor that accepts a user's input signal, that reads metadata, that downloads an advertisement, and that causes the advertisement to be displayed.
In still another embodiment of the invention, a system may include a processor that monitors metadata-selected advertisements; that collects data relating to the metadata-selected advertisement, and that causes the data to be recorded.

FIG. 3 is a flow chart of a process 300 in accordance with various embodiments of the present invention. As illustrated, at step 310, process 300 may begin by receiving metadata and other media. Receiving metadata and other media, as mentioned above, may be accomplished by utilizing a receiver that may receive signals and/or data.
Next, at step 320, process 300 may select an object located within a viewing plane of a viewing device. For example, process 300 may use an audio/video coding method, such as MPEG-4 that allows objects to be defined. The selecting of an object may be accomplished, as mentioned above, by a processor that utilizes a user's input signal. A user's input signal may include the selection of an object displayed on a video display unit with a cursor and/or a command to move a cursor displayed on a video display unit to any point within a video display's viewing plane. A user's input signal, as described above, may be entered through a wired or wireless remote control unit.
To select an object, the processor may be running software that enables certain objects within the viewing plane of a video device to be selected. For example, the processor may utilize visual pattern recognition software that tracks colors, shapes, etc. Alternatively, the processor may utilize a downloaded predefined selectable target area to select objects displayed within the viewing plane of the viewing device.
At step 330, process 300 may read metadata. The metadata may be attached to and/or associated with media or a selectable object imbedded within the media. Reading metadata may be accomplished by a processor. The metadata, as described in detail above, may contain characteristics describing media and/or objects. In addition, the metadata may contain a source address (e.g., a URL) to download an advertisement from a remote location, as also described below.
At step 340, process 300 may select an advertisement. The selecting of an advertisement may be based on metadata attached to and/or associated with media and/or a selectable object imbedded within the media. For example, when media and/or a selectable object within the media is selected, the metadata attached to and/or associated with the media and/or selectable object may be read. Then, an advertisement corresponding to the metadata read may be selected. The advertisement may be selected by comparing the metadata of the media or selected object with metadata from advertisements. The advertisements may be provided from a suitable remote location to the user's equipment at some suitable frequency (e.g., periodically, on-demand, via polling, etc), or may be provided from advertisements previously stored on the user's system, as will be explained below.
Finally, at step 350, process 300 may display the advertisement within the viewing plane of a viewing device.
FIG. 4 is a flow chart of a process 400 in which metadata may be used to select an advertisement and that may be used to implement various embodiments of the present invention. Process 400 shows the receiving and the reading of metadata and other media as well as the selecting and the displaying of an advertisement at steps 410, 430, 440, and 450 respectively. Steps 410, 430, 440, and 450 are substantially the same as steps 310, 330, 340 and 350 which are described in detail above in connection with FIG. 3. Also shown in process 400 is the storing of metadata and other media at step 420. As stated above, the storing of the metadata and other media may be on any suitable storage unit such as a disk drive, or a memory card, etc. The storage unit may be located locally at or near a user's television viewing equipment, or may be located remotely from the user's viewing equipment.
FIG. 5 is a flow chart of a process 500 in which metadata may be used to select an advertisement and that may be used to implement various embodiments of the present invention. Process 500 shows the receiving and the reading of metadata and other media as well as displaying an advertisement at steps 510, 520, and 540 respectively. Steps 510, 520, and 540, are substantially the same as steps 310, 330, and 350 which are described in detail above in connection with FIG. 3. Also shown in process 500 is the downloading of an advertisement based on metadata at step 530. As stated above, metadata may contain a source address (e.g., a URL) to download an advertisement from a remote location. For example, a guidance application utilizing any suitable communication technology (e.g., the Internet using a HyperText Transfer Protocol) may obtain an advertisement by downloading it from a source address. The advertisement that is presented to a viewer may be the advertisement currently available at the source (e.g., a web page). As time passes, the advertiser or the system provider may change the content of the advertisement that is provided to a user by simply modifying the advertisement at the source. In this way, “fresh” advertisements may be presented each time a user plays back a recorded program.
Alternatively, these “fresh” advertisements may be provided by, for example, assigning identifiers to a specific advertisement or a group of advertisements. These advertisements with identifiers may be downloaded and stored in the user's equipment or may be available to a user's system at some remote location available at some suitable frequency (e.g., periodically, on-demand, via polling, etc).
FIG. 6 is a flow chart of a process 600 in which data relating to metadata-selected advertisements may be collected and recorded. Process 600 shows monitoring metadata-selected advertisements at step 610. Monitoring of the metadata-selected advertisements may be accomplished through a receiver and/or a processor, as described above in connection with FIG. 2, blocks 220 and 280, respectively. Furthermore, monitoring may be accomplished at any suitable times (e.g. continuously, periodically, on-demand, etc.). Process 600 also shows collecting data relating to metadata-selected advertisements at step 620. Such collecting of data may be accomplished through a processor, as described in detail above. Finally, process 600 shows the recording of the data. Recording the data may be done on any suitable storage unit such as a, a disk drive, or a memory card, etc.
In addition to monitoring, collecting, and recording, marketing information may also be provided to advertisers over a communications network, as described in detail above. For example, marketing information may be provided to advertisers in a real-time or in a block time format. A block-time format may include daily, weekly, monthly, yearly, etc. information. As stated above marketing information may include information such as the program recorded, the number of times an advertisement is accessed, the time at which the advertisement was accessed, etc., and/or include demographic information associated with a user's account.
Turning now to FIG. 7, a program advertisement screen 700 shows one example of how advertisements may be selected and displayed in accordance with the present invention. Program advertisement screen 700 may include a cursor 710, a metadata-selected advertisement 720, a scene 730, and order button 740. Scene 730 shows a scene in which the user may select an object. Cursor 710 may be controlled by a user through a user input, as described in detail above, and may also be utilized by a user to select an object within the viewing plane of a video device, as depicted in scene 730. Selected advertisement 720 shows a displayed advertisement for the user selected object. If desired, the user may then select order button 740 to order the selected item. The selected item may be charged to a user credit card number, a user's account, and/of any other method or purchasing items from a remote location.
Screen 700 is merely illustrative of screens and methods that may be used to select and display metadata selected advertisements. Any suitable screens and methods of displaying advertisements may be used in accordance with the present invention.
Thus, systems and methods for providing metadata-linked advertisements are provided. Persons skilled in the art will appreciate that the present invention can be practiced by other than the described embodiments, which are presented for purposes of illustration rather than of limitation, and that the present invention is limited only by the claims that follow.
