The memory can store any of a number of pieces or amount of information and data used by the local device 105 to implement the functions of the local device 105. The memory can also store content, such as program code for an application and/or other programs.
3. Authentication Server
In an exemplary embodiment, the processor 405 may be configured to execute instructions stored in the device memory or otherwise accessible to the processor 405. As such, whether configured by hardware or other methods, or by a combination thereof, the processor 405 may represent an entity capable of performing operations according to embodiments of the present invention while configured accordingly. A display device/input device 464 for receiving and displaying content and/or data may also be included in the authentication server 115. This display device/input device 464 may be, for example, a keyboard or pointing device that is used in combination with a monitor. The authentication server 115 further may include memory 463, which may include both read only memory (“ROM”) 465 and random access memory (“RAM”) 467. The authentication server's ROM 465 may be used to store a basic input/output system (“BIOS”) 426 containing the basic routines that help to transfer information to the different elements within the authentication server 115.
In addition, in one embodiment, the authentication server 115 may include at least one storage device 468, such as a hard disk drive, a CD drive, and/or an optical disk drive for storing information on various computer-readable media.

Reference will now be made to
Although the portions of following describe an implementation using an OTA broadcast system, embodiments of the present invention may use a variety of broadcast systems, including a cable broadcast system, a satellite broadcast system, and/or a variety of other systems for transmitting broadcasts. Accordingly, the described examples are provided for illustrative purposes only and should not be taken in any way as limiting embodiments of the present invention to the examples provided.
1. User Registration
In one embodiment, as shown in
In one embodiment, the request to register the user may include user information. The user information may include a variety of information associated with the user and/or the local device 105. For example, the user information may include (a) the user's first and last name, (b) the user's address, (c) the user's zip code, (d) the user's telephone number, (e) a username (f) a charge card number, (g) a local device identifier, e.g., Media Access Control (“MAC”) address or an Internet Protocol (“IP”) address, and/or (h) the like. The user information may be used to uniquely identify the user and/or the local device 105.
As shown in
It should be noted that in various embodiments, the user account may be used to not only store information associated with the user and the local device 105, but additional local devices 105 (e.g., a personal computer and a television in the user's home) and/or remote devices 120. The user account and/or user information may be used to provide content to the local device 105 and/or remote device 120 via the Internet (or other network). In one embodiment, to provide content from the broadcaster to the local device 105 and/or remote device 120 via the Internet, for example, the local device 105 can be authenticated as being within or proximate a broadcaster's broadcast area (e.g., a town, a city, a metropolitan area, a state, a region, a country, and/or the like).
2. Unique Broadcast Identifier Generation
In one embodiment, the authentication process may include the generation of a unique broadcast identifier corresponding to the local device 105. In embodiment, the authentication sever 115 may generate a unique broadcast identifier corresponding to the local device 105 based at least in part on, for example, the user information it receives from the local device 105 (Block 1010 of
In one embodiment, as described, the user information corresponding to the local device 105 can be used to uniquely identify the user and/or the corresponding local device 105. As indicated, the user information may include (a) the user's first and last name, (b) the user's address, (c) the user's zip code, (d) the user's telephone number, (e) a username (f) a charge card number, (g) a local device identifier, e.g., MAC address or IP address, and/or (h) the like. Thus, the unique broadcast identifier generated by the authentication server 115 can also be used to uniquely identify the user, the local device 105, and/or the content (e.g., channels or broadcasters) for which the local device 105 is being or has been authenticated.
In a particular embodiment, the unique broadcast identifier may be, for example, a data string comprising 12 characters. As shown in
As will be recognized, when authenticating multiple local devices 105, the authentication server 115 can generate a unique broadcast identifier for each local device 105 being authenticated. The local devices 105 may be located in any number of different geographic areas. For example, in one embodiment, the authentication server 115 (or multiple authentication servers 115) may create unique broadcast identifiers for local devices 105 in (a) Atlanta, Ga., (b) Clearwater, Fla., (c) Cedar Rapids, Iowa, (d) Seattle, Wash., and/or (e) Los Angeles, Calif. In another embodiment, the local devices 105 may also be within the (a) same geographic area (e.g., Atlanta, Ga.) and (b) same residence or business. For example, multiple user accounts may be associated with a single residential or business location. Thus, in one embodiment, the authentication server 115 (or multiple authentication servers 115) may include or be in communication with a database storing the various unique broadcast identifiers in association with the respective user accounts.
In one embodiment, the unique broadcast identifier may be used as a key, for example, to access any premium content for which the user corresponding to the user account has paid. For example, given that each broadcaster in the United States may have 19.4 megabits per second of spectrum available for broadcast, the broadcaster may be able to simultaneously provide (a) content that is free for user consumption and (b) premium content for which the user pays a fee (e.g., a micro-transaction fee) to access.
In one embodiment, after generating the unique broadcast identifier, the authentication server 115 transmits the unique broadcast identifier to both the broadcast system 100 and the local device 105 (Block 1015 of
3. Authentication
As indicated, the (a) local device 105 can receive the unique broadcast identifier from the authentication server 115 and (b) broadcast system 100 can receive the unique broadcast identifier from the authentication server 115. In one embodiment, as shown in Block 905 of
As will be recognized, when authenticating multiple local devices 105, the broadcast system 100 may broadcast/transmit a burst, for example, with numerous unique broadcast identifiers, each unique broadcast identifier uniquely identifying an associated local device 105 and corresponding content access rights. Thus, for instance, the broadcast system 100 may periodically, continuously, and/or regularly broadcast/transmit the unique broadcast identifiers of registered users regardless of their location with respect to the broadcast system 100. For example, in one embodiment, a broadcaster in Atlanta, Ga. may periodically, continuously, or regularly broadcast/transmit the unique broadcast identifiers for all users in Georgia, the Southeast, and/or the United States. Thus, for instance, KCRG-TV9 in Cedar Rapids, Iowa may broadcast unique identifiers for local devices 105 located in (a) Atlanta, Ga., (b) Clearwater, Fla., (c) Cedar Rapids, Iowa, (d) Seattle, Wash., and/or (e) Los Angeles, Calif. As will be recognized, a variety of approaches and techniques may be used.
In one embodiment, with regard to OTA broadcasts, as shown in
In one embodiment, as shown in Block 710 of
In various embodiments, with regard to OTA broadcasts, an attenuated OTA broadcast (e.g., an attenuated signal) may still be received and be used to identify the unique broadcast identifier therein because the signal carrying the OTA broadcast need only be sufficient to allow identification of the unique broadcast identifier. In other words, as the OTA broadcast reaches the local device 105, the signal need only be sufficient for the local device 105 to recover the data, not the content (e.g., audio and/or video). This approach may allow for local devices 105 that were considered out of range to recover the content of an OTA broadcast to identify the unique broadcast identifier therein.
In one embodiment, after identifying the unique broadcast identifier corresponding to the user and/or local device 105 in the broadcast, the local device 105 can proceed with authentication. In one embodiment, to be authenticated, the local device 105 may need to receive the unique broadcast identifier (a) from the authentication server 115 and (b) via the broadcast (e.g., OTA broadcast, DBS broadcast, and/or cable broadcast) from the broadcast system 100 (Block 720 of
In one embodiment, as part of the local device 105 being authenticated, the local device 105 may store the unique broadcast identifier for use in accessing content from the broadcaster via the Internet (or other network). Moreover, the local device 105 (e.g., via a downloaded or preinstalled module, program, or application) can generate and transmit a notification to the authentication server 115 regarding the local device's 105 authentication status. The authentication status may indicate, for example, whether and for which channels the user and/or local device 105 have been authenticated. In response to (e.g., after) receiving the notification from the local device 105, the authentication server 115 can store the local device's 105 authentication status in association the user account corresponding to the user and/or the local device 105 (Block 1020 of
As will be recognized, when authenticating multiple local devices 105, the authentication server 115 can generate a unique broadcast identifier for each local device 105 being authenticated. Thus, at any given time, a broadcast system 100 may broadcast/transmit a burst with numerous unique broadcast identifiers, each uniquely identifying an associated local device 105 and corresponding content access rights. Similarly, a local device 105 may receive numerous unique broadcast identifiers, but only identify (e.g., be able to translate) the unique broadcast identifiers to which it corresponds.
The preceding describes a process for authenticating a local device 105 in a broadcast area. In various embodiments, this may allow a broadcaster to confirm that the local device 105 is within or proximate the broadcaster's broadcast area. Thus, after the local device 105 has been authenticated, the broadcaster can provide content to the local device 105 via a network such as the Internet while, for example, complying with various distribution regulations.
4. Content Access for Local Device
In one embodiment, after the local device 105 has been authenticated, the local device 105 can access content (e.g., via a user operating the local device 105) via the Internet, for example. As discussed, the content may include television broadcasts, television programs, movies, datacasts, music, images, videos, text, webpages, and/or the like. To access such content, the local device 105 may generate a request for the desired content (Block 735 of
In one embodiment, the request for content is received via the authentication server 115 (Block 1025 of
The content can be transmitted to the local device 105 in a variety of ways. For example, in one embodiment, the authentication server 115 can be used to transmit the content from the broadcaster to the local device 105 via the Internet (or other network). In another embodiment, the authentication server 115 can transmit a notification to the broadcaster to provide the specified content to the local device 105 via the Internet (or other network), bypassing the authentication server 115 for distribution of the content. As indicated in Block 740 of
In one embodiment, the local device 105 may access content (e.g., via a user operating the local device 105) that is currently being broadcast (e.g., via an OTA broadcast, a DBS broadcast, and/or a cable broadcast). For example, the local device may access (e.g., via a user operating the local device 105) the television show “Lost” 35 minutes after the Lost broadcast began. In this example, the authentication server 115 and/or broadcast system 100 may allow the local device 105 to receive the content (e.g., the television show Lost) via a network such as the Internet (a) that is currently being broadcast or (b) from the beginning of the show Lost. As will be recognized, a variety of other approaches and techniques may also be used.
In various embodiments, the described process allows the physical location of the user (e.g., local device 105) to be established. With the physical location of the user (e.g., local device 105) established, the broadcaster or third party can identify content the user is permitted to receive via the Internet (or other network). For example, the broadcaster may simply provide (e.g., stream) its broadcast content via the Internet (or other network) to authenticated users (e.g., devices). The broadcaster may also enter into agreements to distribute other content to authenticated users (e.g., devices) over the Internet (or other network) within or associated with the broadcaster's broadcast area. For example, KCRG-TV9 may enter into an agreement with ESPN to distribute ESPN's live content (e.g., content normally only available via a subscription for satellite or cable services) over the Internet (or other network) to authenticated users (e.g., devices) within or associated with KCRG-TV9's broadcast area. Additionally, broadcasters such as KCRG-TV9 may also require a subscription (and fee) to receive ESPN's live content via the Internet (or other network) in KCRG-TV9's broadcast area. In addition to providing such content, the broadcaster may provide VOD content, pay-per-view (“PPV”) content, and a variety of other content via the Internet (or other network) to authenticated user (e.g., devices). In various embodiments, these concepts may allow broadcasters to distribute an unlimited amount of content (e.g., channels) to local devices 105 and remote devices 120 via a network such as the Internet. These embodiments can be further used to create virtual broadcast boundaries that, for example, track cable and/or broadcast area boundaries.
5. Content Access for Remote Device
As indicated, the term remote device may refer to, for example, a device located outside a specific service area when attempting to access content associated with the service area (e.g., a device located outside a broadcaster's broadcast area when attempting to access the broadcaster's content). Although, in certain embodiments, the remote device 120 may also be located within a broadcaster's broadcast area when attempting to access the broadcaster's content. For example, a remote device 120 may be a user's mobile phone, laptop, or television that, at various times, may be within or outside a specific broadcast area.
In one embodiment, after the local device 105 has been authenticated as being within or proximate a broadcast area, the remote device 120 may be able access the broadcaster's content via the Internet, for example, when outside the broadcast area. To do so, the remote device 120 can first be registered with the local device 105 (Blocks 745, 800 of
In one embodiment, after the remote device 120 has been registered, the remote device 120 may generate and transmit a request for the unique broadcast identifier to the local device 105 (Block 805 of
In one embodiment, after receiving the unique broadcast identifier, to access such content, the remote device 120 may generate a request for the desired content (Block 815 of
The content can be transmitted to the remote device 120 in a variety of ways. For example, in one embodiment, the authentication server 115 can be used to transmit the content from the broadcaster to the remote device 120 via the Internet (or other network). In anther embodiment, the authentication server 115 can transmit a notification to the broadcaster to provide the specified content to the remote device 120 via the Internet (or other network), bypassing the authentication server 115 for distribution of the content. As indicated in Block 820 of
In various embodiments, because the local device 105 has been authenticated as having a presence within or proximate the broadcaster's broadcast area, the user's registered remote devices 120 can be used to access content from the broadcaster when outside the broadcast area. For example, a user may take her mobile phone or laptop on a business trip or vacation outside the broadcaster's broadcast area. In such a case, the described authentication can allow the user (or other parties) to access content (e.g., stream a newscast or television program) from the broadcaster even when outside the broadcaster's broadcast area. This may allow the user to access a broadcaster's content regardless of location and/or device.
In one embodiment, the user may be limited in the number of remote devices 120 that can be registered for access to content. For example, the user may only be able to register five devices with the local device 105. In various embodiments, this may limit fraud attempts by users in registering friends' or relatives' remote devices 120 for access to content outside a specific broadcast area.
6. Content Metrics
In one embodiment, a broadcaster can monitor metrics associated with the content it distributes to local and remote devices 105, 120. For example, periodic channel scans on local devices 105 and/or remote devices 120 can be executed to obtain information about the content (e.g., channels, VOD content, and PPV content) being received by the devices. This information can then be transmitted by the local and remote devices 105, 120, for example, to (a) the broadcaster or (b) the authentication server 115. In various embodiments, this may allow the broadcaster to obtain viewer metrics, such as who is watching what and when. Accordingly, precise statistical information regarding user consumption can be obtained. Additionally or alternatively, this may also allow a broadcaster to verify whether a device (e.g., local device 105 and/or remote device 120) is indeed receiving a broadcast.
7. Advertisements
As described, a broadcaster may enter into agreements to distribute content from other parties within specific broadcast areas. For example, KCRG-TV9 may enter into an agreement with ESPN to distribute ESPN's live content over the Internet (or other network) to authenticated users (e.g., devices) within or associated with KCRG-TV9's broadcast area. By identifying the actual physical location of the local device 105, the broadcaster or independent third party may sell targeted advertising positions for its content. For example, for content provided by KCRG-TV9 via the Internet (or other network), KCRG-TV9 may sell advertising positions to clients interested in targeting an audience in Cedar Rapids, Iowa. In various embodiments, this may allow a broadcaster to sell local advertising positions for insertion into the content provided via the Internet (or other network).
