Advertising is a widespread model for businesses to provide information about products to people. The value to the advertiser comes from the products purchased and payment for the advertisements is typically on the basis of the number of viewers. The advertiser therefore wants to target advertisements at viewers who have demonstrated that they are more likely to be interested in the products, thereby converting the minimum number of viewers paid for to the maximum number of products purchased. This, for instance, is what lead to the development of the “soap opera”—programming whose content was deliberately designed to appeal to the potential customers for detergent soaps.
Many products have addressed methods of improving advertisement targeting by profiling the potential audience, both in public multi-media displays and in the context of Personal Video Recorders (PVRs). In public locations, the methods typically assume that a user has specified a profile which is carried around on a mobile devices such as a Personal Digital Assistant (PDA) or mobile phone and an advertisement display system collects the profiles of those in the area in order to decide which advertisement to display. In the PVR context, the methods are an extension of the conventional TV model, in which the advertisements displayed are a function of the content viewed.

In
A man 120 shops for groceries while his PDA 125 acquires at least one AIM 127 from the store 123. A woman 140 at an airport 143 acquires at least one AIM 147 while carrying her mobile phone 145. A man 160 leaves a car wash 163, where his PDA 165 has acquired at least one AIM 167.
Reference is now made specifically to
In the second panel of
It is appreciated that in some preferred embodiments wired communication may be used for transferring at least one accumulated AIM 167 to the CDU 220. It is further appreciated that wherever in the present specification wireless communication is mentioned, wired communication may alternatively be used, as is known in the art.
In an alternative preferred embodiment the CDU 220 presents a query to the Philip 160, requiring Philip 160 to explicitly authorize transfer of the at least one accumulated AIM 167 from the mobile device mobile device to the CDU 220. The at least one accumulated AIM 167 is preferably transferred to the CDU 220 only upon receipt to a positive answer to the querying.
The table of AIMs 210 in CDU memory is preferably updated to reflect the addition of the at least one AIM 167. Once the at least one AIM 167 is transferred, no AIMs remain in the PDA 165. As described above, AIMs are analogous to currency; specifically, once an AIM is transferred, it is as though the AIM has been “spent”, and the AIM is no longer available in the PDA 165 for use.

The mobile device 500 preferably comprises an AIM receiver 520, an AIM storage unit 530 and an AIM sender 540. The mobile device 500, via any appropriate wireless protocol, preferably receives at least one AIM (not shown in
Transfer of AIMs, whether from the AIM source 510 to the AIM receiver 520, or from the AIM sender 540 to the CDU 600 preferably comprises secure transfer. For example, and without limiting the generality of the foregoing, the AIM is RSA signed using a private key provided in a device certificate. Security information added to the AIM is referred to in the present specification as a “security wrapper”. The security wrapper may preferably be provided by the advertisement aggregator or, alternatively, by the AIM distribution terminal.
The mobile device 500 may preferably be registered with the CDU 600 in the home. Registration links the mobile device 500 to the CDU 600 in a permanent or semi-permanent way, but is preferably revocable through an “unregistration” process canceling the original registration. Preferably, two different types of registration processes, comprising a complex registration process and a basic registration process, are provided. The complex registration process preferably establishes a one-to-many relationship between one mobile device 500 and many CDUs 600. It is appreciated that a plurality of mobile devices may each undergo the complex registration process, thereby establishing a many-to-many relationship between the plurality of mobile devices and many CDUs 600. The basic registration process establishes a one-to-one relationship between one mobile device 500 and only one CDU 600. In addition, several different mobile devices 500 can execute the basic registration process with one CDU 600.
It is appreciated that more than one registered device may be associated with a particular individual. For example, and without limiting the generality of the foregoing, Philip 160 (
In the complex registration process, for example, a mobile device 500 may preferably be linked to all the CDUs 600 in the home and all the residents may link their personal devices to the CDUs 600 in the public areas of the home, whereas only the parents' personal devices are linked to a TV in the parents' bedroom.
Registration thus preferably comprises listing the mobile device 500 in the CDU 600, by issuing a unique shared registration number that is stored in both the CDU 600 and the mobile device 500. Preferably, secure identity exchange between the mobile device 500 and the CDU 600 is performed based on random challenge using public key authentication schemes. For example, and without limiting the generality of the foregoing, public key authentication schemes such as X.509, IpSec or SSL may preferably be used. The registration process may optionally include entry of personal user information, such as, for example, one or more of the following: name; role in household; password; credit card or e-wallet information; and any other appropriate information. Personal information is useful for other functions; for example, and without limiting the generality of the foregoing, personal information may be useful in interactive television applications. The personal information is preferably guarded by mechanisms to protect privacy, as are well known in the art, to ensure that the personal information is not revealed when the CDU 600 performs functions for which personal information is not required.
Registration is preferably initiated when the CDU 600 or mobile device 500 detect each other. If the mobile device has never been registered before, the mobile device preferably triggers a message to the user either on a screen on the mobile device 500, or on a screen associated with the CDU 600. Alternatively a user may initiate the registration process through a menu entry available in either the screen on the mobile device 500, or on the screen associated with the CDU 600. Registration is preferably user initiated in the complex registration scheme, described above, when the mobile device is already registered with at least one CDU.
In the basic registration process, a mobile device 500 is registered in one and only one CDU 600 at a time. Before the mobile device 500 can be registered elsewhere, the mobile device preferably revokes initial registration—for instance, registration might use Frank Stajano's Resurrecting Duckling scheme as described in Security for Ubiquitous Computing, referred to above, on pages 88-105. Under this approach, all AIMs may only be loaded into the particular CDU 600 where the mobile device 500 is registered. Alternatively, in the basic registration method, loading the AIMs only when they are to be used by the display device can support transitory use.
By contrast to the basic registration process, in the complex registration process, the mobile device 500 can preferably be registered in a plurality of CDUs 600. The complex process is preferably similar as the basic process described above, except that, in the advanced registration process a mobile device 500 stores many registration records. Because the mobile device 500 may preferably be registered in many CDUs, in embodiments using the complex registration process, AIMs are preferably not transferred automatically from the mobile device 500 to one of a plurality of CDUs. When multiple registrations exist, AIMs are preferably transferred in one or more of the following cases:
It is appreciated that in the preferred embodiment where the mobile device 500 may preferably be registered in many CDUs, and nonetheless a particular mobile device is registered in only one CDU, the particular mobile registered in only one CDU device will only transfer AIMs to that one CDU.
Reference is now made to
The advertisements 660 stored in the CDU 600 are preferably delivered to the CDU 600 by an advertisement aggregator 680 in a plurality of data streams 690 comprising advertisements.
Reference is now made to
The CDU preferably determines if the mobile device is registered or not (step 730) by comparing the identity stored in the mobile device (described above with reference to
It is appreciated that the loading of AIMs onto the CDU and the deleting of AIMs from the mobile device in step 750 preferably occurs in several steps. For example, and without limiting the generality of the foregoing, AIMs stored on the mobile device are preferably marked as pending deletion upon transfer. The AIMs marked pending deletion are preferably deleted after a timeout, unless a resend request is received from the CDU. Alternatively, the AIMs marked as pending deletion are preferably deleted from the mobile device when confirmation of receipt is received from the CDU. In theory, it may even occur that deleting of AIMs from the mobile device may happen before the AIMs are finished loading on the CDU.
Throughout the present specification and claims, the term “push”, in all of its grammatical forms refers to push technology, a data distribution technology in which selected data is automatically delivered into a user's receiving device at prescribed intervals or based on some event that occurs.
If the CDU determined that the mobile device is not a registered device in step 730, or if the mobile device is registered on a plurality of CDUs, no AIMs are immediately transferred. Rather, the mobile device, using an appropriate secure protocol, notifies the CDU which A are available (step 760). In some preferred implementations of the present invention, the user may push AIMs from the not-registered device into the CDU. For example, and without limiting the generality of the foregoing, the user may wish to spend time watching music videos on a CDU on which his mobile device is not-registered. In such a case, the user may desire to push his AIMs and use the AIMs to “purchase” the music videos. When an opportunity to display an advertisement occurs, the CDU preferably determines, based on available AIMs, which advertisement to play out, preferably as explained below with reference to
Reference is now made to
The AIM distribution terminal 800 preferably comprises an AIM receiver 820 an AIM storage unit 830, and an AIM dispenser 840. The AIM receiver 820 is preferably operative to securely receive at least one AIM from the advertisement aggregator 810. The at least one AIM received is sent for secure storage in the AIM storage unit 830. At a time when a mobile device 850 is in communication proximity, the AIM dispenser 840, using an appropriate wireless protocol, securely dispenses at least one AIM to the mobile device 850. Responsibility for providing the security and preferred methods for securing AIMS are discussed above with reference to

It is appreciated that an advertisement may belong to more than one category. For example, and without limiting the generality of the foregoing, an advertisement may cost either 2 star advertisement points or 3 square advertisement points.
It is further appreciated that when the registered user has more than one registered device, as explained above with reference to
However, if only registered user Philip is present, then Dina's advertisement points are preferably given lower priority, so that there are more square category advertisement points than advertisement points of any other category. In such a case, an advertisement corresponding to the square category of AIM is preferably displayed.
When more advertisement points for a given category of advertisement points are available than are needed to display an advertisement for that given category, the following criteria are preferably used to determine which advertisement points are deleted:
Persons skilled in the art will appreciate that any number of appropriate schemes may be devised to determine which weighting to give according to previously loaded AIMs, presence and absence of registered users and guests. For example, and without limiting the generality of the foregoing, the CDU is preferably configurable to adopt one of the two following schemes for prioritizing from which user to deduct advertisement points:

It is appreciated that steps 1130 and 1155 may occur whenever appropriate, that is, asynchronously with respect to each other.
Reference is now made to
A quantity of points 1220 is also preferably comprised in the AIM. The metadata 1240 and quantity of points 1220 are preferably enclosed in a security wrapper 1230 designed to protect the AIM from tampering. A preferred implementation of the security wrapper is described above with reference to
Reference is now made to
The advertisement payload 1310 preferably comprises any one or combination of the following video; audio; interactive data; and other data displayed or made available when the ad is played out, as is known in the art.
Reference is now made to
A first advertisement aggregator 1405, or some other comparable AIM distributing authority, contracts with a first advertiser to provide 10,000 AIMs 1410. The 10,000 AIMs 1410, of a category relevant to the first advertiser, are denoted in
While two advertisement aggregators comprising the first advertisement aggregator 1405 and the second advertisement aggregator 1415 are shown in
The at least one AIM distribution terminal 800 distributes the square and star category AIMs 1460 to various mobile devices 1470. When the various mobile devices 1470 are in proximity with at least one CDU 1480, AIMs 1460 are transferred to the at least one CDU 1480. At an appropriate time the at least one CDU 1480 plays out advertisements 1490 based on received AIMs 1460. Periodically, the at least one CDU 1480 will report back 1495 to a clearinghouse, the report preferably comprising information concerning which AIMs have been used and/or which advertisements have been used.
If all advertisements use only one point, and if each act of AIM distribution gives out one point only, the reporting can be simplified, as the AIM with its secure wrapper is all that need be reported If multiple points are distributed in AIMs or multiple points are used to display advertisements, then a report preferably comprises: a total count of points used; metadata identify,g the advertisements displayed, and a sub-report of AIMs used. The sub-report preferably comprises copies of at least one used AIM or excerpts thereof, preferably securely wrapped.
It is appreciated that the clearinghouse may comprise either or both of the first advertisement aggregator 1405 and/or the second advertisement aggregator 1415, or may comprise yet a third authority not shown in

In referring to entitlements stored in the embedded chip 1530 and in the claims, the terms “enabled” and “disabled” are used, in all of their grammatical forms, to describe an attribute of the entitlement or entitlements. The term “disabled” is used to refer to an entitlement that is present, but which entitlement is marked in some way or has some attribute which prevents the entitlement from being used in any way. As described more fully below, such a disabled entitlement may be enabled, at which time the disabled entitlement becomes an enabled entitlement.
In referring to entitlements stored in the embedded chip 1530 and in the claims, the terms “active” and “inactive” are used, in all of their grammatical forms, to describe an attribute of the entitlement or entitlements, particularly although not necessarily exclusively an attribute of an enabled entitlement. Generally, an enabled entitlement may, as described more fully below, not yet be ready to be used; such an enabled entitlement is referred to as an “inactive” entitlement An enabled entitlement that is ready to be used, as described more fully below, is referred to as an “active” entitlement.
In one preferred embodiment, while the box of cereal 1520 has not yet been purchased, the embedded chip 1530 stores a disabled entitlement for content, as will be explained below.
Referring now to the second pane of
In an alternative preferred embodiment, while the box of cereal 1520 has not yet been purchased, the embedded chip 1530 does not yet store any entitlement for content When the user 1510 pays for the box of cereal 1520, an enabling device 1540 preferably enables the embedded chip 1530, by securely sending the entitlement using any appropriate wireless protocol to the chip. A further step may be required to activate the entitlement, as explained below.
The entitlement preferably comprises at least: rights granted to content; a period that the rights are granted for; and a location-of-distribution identifier. The location-of-distribution identifier need not explicitly identify a particular item of content; mapping to a particular item of content may be carried out when the entitlement is used. For example, and without limiting the generality of the foregoing, the location-of-distribution identifier may grant rights to view one episode of a series of cartoons, without specifying which particular cartoon may be viewed The particular-cartoon, and hence the location of the particular cartoon, may be specified at a later time.
Referring now to the third pane of

Referring now to the second pane of
In alternative preferred embodiments, the entitlement could comprise an entitlement for any one episode of a content series; content usage over a period of time or until an expiration date; or a specific number of playouts (for example and without limiting the generality of the foregoing, any episode may play out three times). In preferred embodiments in which the entitlement comprises more than an entitlement to an individual piece of content for one time viewing, the entitlement may preferably be preserved in the original embedded chip 1535, from where the entitlement can be sent to another playout device in the future. The entitlement may preferably be altered to indicate what usage has already occurred, and the entitlement may then be sent to other playout devices with reduced value,.or may be deleted from the original embedded chip 1535. Usage management of the entitlement would now be handled in the playout device to which the entitlement was transferred.
Playing out of the content associated with the enabled entitlement as described above may occur either passively or actively:
Alternatively, and as shown in the example of the third pane of
Alternatively, sensors may preferably be used to activate the entitlement. For example, and without limiting the generality of the foregoing, light sensors may sense light when a box containing the entitlement is opened, thereby activating the entitlement. Other non-limiting examples would include temperature sensors which may preferably sense that a box containing the entitlement is being held, or that clothing comprising the sensor is being worn.
The playout device 1550 corresponds to the CDU 600 of the system of
It is appreciated that in the system of
In some preferred embodiments of the system of
The plurality of playout devices belonging to the user is preferably configured by the user to share a common domain identification name or number and a common domain encryption key. When the entitlement is transferred to one of the plurality of playout devices belonging to the user, the playout device preferably adds information to the entitlement, or encrypts the entitlement so that the entitlement may only be used within the user's personal domain. For example, and without limiting the generality of the foregoing, only devices sharing the common domain encryption key may decrypt the encrypted entitlement.
In some preferred embodiments of the systems of
In an alternative preferred embodiment, the embedded chip 1530 may preferably comprise an enhanced RFID. RFIDs, such as tags attached to clothing in order to protect against theft from stores, are inactivated when the user 1510 pays for an object associated with an attached RFID. An RFID system comprises a reader (or interrogator), an associated antenna and transponders that carry data. The reader transmits a low-power radio signal, through the antenna, that the tag receives via its own antenna to power an integrated circuit. Using energy generated when the signal enters the tag's radio field, the tag will briefly “converse” with the reader for verification and exchange of data Once the data is received by the reader the data can preferably be sent to a controlling computer for processing and management.
Reference is now made to
The entitlement is enabled and/or activated (step 1725). The term “authorize” (step 1725) used in
The entitlement is preferably transferred using one of the following transfer mechanisms:
Once the authorized entitlement is transferred to the playout device 1550, the entitlement in the manufactured article 1520 is disabled and/or deactivated (step 1740). The term “deauthorize” used in
The playout device reads the entitlement (step 1750) and requests the content from the location comprised in the entitlement (step 1760).
The content arrives at the playout device (1770). The playout device then plays out the content (step 1780).
It is appreciated that the entitlement may preferably comprise a non-specific entitlement For example, and without limiting the generality of the foregoing, the entitlement may entitle the user 1510 to view one or more non-specific episodes of a cartoon series rather than just one particular cartoon.
