DETAILED DESCRIPTION
In FIG. 1, a wireless communication system 100 comprises generally a wireless terminal 102 that communicates in a wireless communication network 104, for example, in a cellular communication network, which may be communicably coupled to other networks. In FIG. 1, for example, the wireless communication network is communicably coupled to the Internet and/or some other open or proprietary network(s) 106. The architecture of wireless communication networks is known generally and thus not discussed in further detail. Exemplary cellular communication networks include 3GPP GERAN based networks, for example, GSM/EGPRS and Enhanced Data-rates for GSM (or Global) Evolution (EDGE) networks, CDMA networks and 3rd Generation 3GPP WCDMA and 3GPP2 CDMA networks, among other existing and future generation cellular communication networks.
In FIG. 1, the wireless communication system also includes a wireless broadcast service content provider 108, for example, a DVB-H broadcast network operator. The content service provider 108 broadcasts content for reception by wireless terminals capable of receiving such broadcasts. In some embodiments, the wireless terminal is configured with a broadcast receiver, for example, a DVB-H receiver. Users typically subscribe to broadcast services, although service subscription is generally not required. The integration of broadcast and wireless communication networks is known generally and thus not discussed in further detail.
In FIG. 2, the wireless terminal 200 includes a wireless, e.g., a cellular, transceiver 210 and a broadcast receiver 220, e.g., DVB-H receiver, both of which are communicably coupled to a controller 230. The terminal also includes a user interface 240 communicably coupled to the controller. The user interface may comprise a video display, a keypad or other input device, audio inputs and outputs, and corresponding controls among other inputs and outputs. The wireless terminal typically includes other inputs and outputs known generally by those having ordinary skill in the art and thus not illustrated in the drawing. In some embodiments, the wireless terminal includes a broadcast receiver but not a wireless communication transceiver.
In the process 300 of FIG. 3, at 310, a wireless terminal including at least a broadcast content receiver, for example, the terminal 200 of FIG. 2, receives preview information at the broadcast content receiver. Thus the preview information is sent via the content provider, for example, the broadcast content provider 108 in FIG. 2. In one embodiment, the preview information is sent as part of, or is referenced, by an Electronic Service Guide (ESG).
The preview information references content not yet received by the wireless terminal. The preview information may be in the form of a preview video clip or trailer or some other promotional information that references content that may be purchased or otherwise obtained by the user. The content referenced may be multimedia content, e.g., audio and/or video, polls, games, or any other type of content. The terminal user typically views the preview information to decide whether to download or otherwise obtain the referenced content. The downloading may be performed at prescribed time periods or it may be performed on-demand. In some embodiments, the referenced content is provided by the broadcast service provider and received by the broadcast receiver on the wireless terminal. In other embodiments, the content is obtained from some other source. For example, the referenced content may be obtained from a third party content provider via the wireless communication transceiver. In some but not all embodiments, the terminal user exchanges some consideration for right to obtain the referenced content. The consideration exchanged may be monetary, e.g., account billing, or it may be information, e.g., an e-mail address, provided to the content provider.
In one embodiment, the wireless terminal communicates or negotiates with the content provider to obtain the referenced content. In other embodiments the communication or negotiation is made via a proxy entity. In FIG. 2, for example, a request for the referenced content may be communicated to the content provider via the broadcast content provider 108 or it may be communicated via the mobile radio network operator 104.
In some embodiments, the referenced content has an expiration time associated with it. For example, the temporal availability of the content or something associated with the referenced content may be limited. In some embodiments, content availability may be based on a promotional event. For example, the referenced content may be available at a particular price for a limited time period. In another example, bonus content may be provided if the referenced content is purchased within a specified time period. In another embodiment, the time period during which a user may respond to a poll or participate in a survey or play a game may be limited. Thus, generally, the availability of the reference content or something associated therewith may be discontinued after a specified time period.
In FIG. 3, at 320, according to a related aspect of the disclosure, the wireless terminal receives an expiration notification for content referenced by preview information. In one embodiment, the expiration notification is received by the communication transceiver from the content service provider, for example, from the broadcast content provider 108 in FIG. 1. In a related embodiment, the broadcast content expiration notification is communicated to the wireless terminal in the Electronic Service Guide as part of a metadata tag. In some embodiments, the expiration information includes URI or other address information indicating from where the content may be obtained, for example, from a third party content provider.
In another embodiment, the expiration notification is received by the communication transceiver from a wireless communication network other than the content service provider. For this embodiment, in FIG. 1, the mobile radio network operator 104 transmits the expiration notification to the wireless terminal 102, which receives the expiration notification via a wireless receiver rather than by the broadcast receiver. The expiration notification may be sent to the wireless terminal via a message, for example, a short message service (SMS) message or a multimedia message service (MMS) message or an instant message (IM). Generally, the expiration notification may be communicated in a point-to-point communication or in a broadcast communication. In other embodiments, the expiration notification is communicated to the wireless terminal by some other mechanism.
In embodiments where the expiration notification is sent to the wireless terminal via a wireless communication network other than the content service provider, the content provider may communicate the expiration notification information to the wireless communication network for forwarding to the wireless terminal. In one embodiment, the broadcast content expiration notification is communicated to the broadcast client in the Electronic Service Guide as part of the PreviewData metadata tag via the cellular network or broadcast network. This notification to the broadcast client may also be communicated to the end user over a cellular messaging application, e.g., via SMS, MMS. In one embodiment, the wireless communication network receives content expiration notification information for broadcast content available to communication terminals in the wireless communication network from the content provider. The wireless communication network then sends a content expiration notification, based on the content expiration notification information, to one or more communication terminals over the wireless communication network. In one embodiment, the content expiration notification is pushed to the communication terminal in the absence of a request from the communication terminal.
In FIG. 3, at 330, the wireless terminal indicates, on a user interface thereof, content expiration information for the content referenced by the preview information after receipt of the expiration notification. In one embodiment, the content expiration information is indicated automatically, preferably before the content referenced by the preview information expires. The content expiration notification may be in the form of a prompt reminding the user of the expiration of, or a last chance opportunity to obtain, the referenced content or a promotion or other information associated therewith. In some embodiments, the wireless terminal provides multiple content expiration information prompts associated with the expiration of the referenced content. The prompts may be based on receipt of a single expiration notification or on multiple notifications. In one embodiment, the frequency with which the multiple content expiration information prompts are presented at a user interface of the wireless terminal increases as the expiration time approaches, thus creating a sense of urgency for the user.
In the wireless communication terminal 200 illustrated in FIG. 2, the controller 230 includes an expiration notification module 232 that controls the presentation of the content expiration information or prompts on the user interface of the wireless terminal. The module generates content expiration prompts based on the expiration notification received by the wireless terminal. The module is typically implemented by software, although it may be implemented by an equivalent hardware circuits or modules or combination of hardware and software. In the process diagram 400 of FIG. 4, at 410, a wireless device user subscribed to a mobile broadcast content service is provisioned with a broadcast (BCAST) service capabilities/profile. The wireless terminal user may have the ability to activate or deactivate this capability through the service provider. This would likely include the subscription or device characteristics, etc. The profile and configuration is not an essential part of the invention. At 420, the content preview information along with metadata/ESG is transferred to the wireless device with content time/expiration window information.
In FIG. 4, at 430, BCAST content, including any associated content, is purchased or consumed by the wireless terminal. When content referenced by preview information is near expiration at 440, the user is prompted of the expiration based on the expiration notification, which may be received from the wireless communication network, for example, from the MMSC or SMSC or from the broadcast service provider. At 452, as an optional component of the expiration notification, the user may be prompted for additional time-constrained content such as polls, games, etc. At 460, the referenced content is installed if the user opts to download the content.
In FIG. 5, at step 1, a wireless terminal embodied as a mobile device 510 transfers preview content/metadata 522, for example, as part of an Electronic Service Guide (ESG), from a BCAST server 520. At step 2, the wireless terminal 510 launches a BCAST client application for decoding and processing the ESG with the PreviewData metadata. At step 3, a BCAST user agent 512 on the wireless terminal checks the ESG for validity, form and processes the metadata. Upon validation with the user at step 4, the preview information is viewed by the user. Step 5 illustrates an example of the network pushing an expiration notification to the device if the full broadcast content has not yet been purchased or consumed by the user. This is coming from the network source, e.g. broadcast server or cellular network. The broadcast client will check the expiration parameters and notify the user of the impending expiration in steps 6 and 7. The final step is to acknowledge receipt of the content if consumed by the device.
While the present disclosure and the best modes thereof have been described in a manner establishing possession and enabling those of ordinary skill to make and use the same, it will be understood and appreciated that there are equivalents to the exemplary embodiments disclosed herein and that modifications and variations may be made thereto without departing from the scope and spirit of the inventions, which are to be limited not by the exemplary embodiments but by the appended claims.
