Each of the above stated applications is hereby incorporated herein by reference in its entirety.
Certain embodiments of the invention relate to a broadband gateway. More specifically, certain embodiments of the invention relate to a method and system for customized acquisition of content by a broadband gateway.
With the continuous growth of digital television or broadcast multimedia, and/or broadband access, which may be used in conjunction with online businesses, social networks, and/or other online services and applications, users may desire having access to a larger number of providers and/or a broader range of content in a manner that is flexible and/or suits the users' lifestyles. Most users connect to the Internet using web browsers running on personal computers (PCs). Furthermore, most households may have one or more televisions that may be used to view television and/or multimedia broadcasts. Television broadcasts may include terrestrial TV, Cable-Television (CATV), satellite TV and/or Internet Protocol television (IPTV) based broadcasts. To ensure against unauthorized reception and/or use of TV and/or multimedia broadcast, service providers may require use of dedicated set-top boxes (STBs) that may be used to encrypt broadcast signals communicated from the service providers to generate suitable video and/or audio streams that may be played via televisions and/or other display/playback devices in the household. Furthermore, STBs and/or TVs may support Internet access. Thus, rather than using a computer to access the Internet, a user may find it more convenient to use the flat screen televisions and/or monitors in homes for the same purpose. To do so, for example, an STB communicatively coupled to a flat screen television may be provided with web browsing software and protocols, and Internet connectivity, which may enable the user to easily access the Internet or check their electronic mail (email), for example, from a convenient and comfortable location such as their living room.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.
A system and/or method is provided for customized acquisition of content by a broadband gateway, substantially as illustrated by and/or described in connection with at least one of the figures, as set forth more completely in the claims.
These and other advantages, aspects and novel features of the present invention, as well as details of an illustrated embodiment thereof, will be more fully understood from the following description and drawings.
Certain embodiments of the invention may be found in a method and system for customized acquisition of content by a broadband gateway. In various embodiments of the invention, a broadband gateway may be operable to determine options for acquiring particular content.

The broadband gateway may be operable to select one of the options for acquiring the content based on the ranking. The broadband gateway may support a plurality of physical layer connections to a corresponding plurality of network access service providers. One or more of the options may be available via a first one of the plurality of physical layer connections and one or more of the options may be available via a second one of the plurality of physical layer connections. The one or more characteristics may comprise one or more of: a provider associated with each of the options, a time of availability of each of the options, a quality of the particular content associated with each of the options, a power consumption associated with each of the options, and a price associated with each of the options.
The user specified criteria may comprise one or more of: criteria for selecting between the options based on providers associated with the options, criteria for selecting between the options based on a time at which each of the options can be acquired, criteria for selecting between the options based on quality of a version of the particular content associated with each of the options, criteria for selecting between the options based on power consumption associated with acquiring and consuming the content, and criteria for selecting between the options based on a price associated with each of the options. The user-specified criteria may be stored in memory in the broadband gateway. The gateway may rank the determined options based on attributes of one or more devices via which the particular content will be consumed. The attributes may comprise one or more of: a display resolution of the one or more devices, a decoding technique supported by the one or more devices, and a bandwidth of a connection between the one or more devices and the broadband gateway. The attributes may be stored in memory in said broadband gateway.
The broadband gateway may be operable to generate a score for each one of the options and the options may be ranked based on the score. The score of an option may be generated by assigning one or more coefficients to the one or more characteristics of the options, weighting the one or more coefficients by one or more corresponding weighting factors, and summing the weighted coefficients. The weighting factors may be determined based on the user-specified criteria and/or on the attributes of one or more devices by which the particular content is to be consumed.

As illustrated in
In operation, for particular content that is to be delivered from a provider 120 and/or 130 to a device 104, the gateway 102 may be operable to discover various options for obtaining the particular content. The gateway 102 may be operable to rank the available options and select the highest-ranking option.
In an embodiment of the invention, different options for obtaining particular content may be characterized by, for example, different prices, different power requirements, different providers, different versions or quality of the content, and/or different times at which the content is available. For example, a search performed by the gateway 102 may discover two options available for viewing “TV show.” The first option may enable streaming a lower-quality version of “TV show” from a first provider at a first price, and a second option may provide for waiting a day and downloading a higher-quality version of “TV show” from a second provider at a second price. The gateway 102 may rank the options based on the characteristics of the options. Although five characteristics are described for illustration, the invention is not limited to any particular characteristics or number of characteristics.
In an embodiment of the invention, the options for receiving particular content may be ranked based on how well their characteristics fit with user-specified criteria. For example, a user may specify that he wants the highest-quality version of content that is available regardless of cost, time of delivery, or provider. Quality may refer to, for example, resolution, frame rate, 2-D video vs. 3-D video, frame loss, and/or compression level. Accordingly, the gateway 102 may, for example, rank the options from highest quality of the content to lowest quality of the content. For another example, a user may specify that he is willing to pay up to $X for the content if he can acquire the content within 24 hours otherwise he is only willing to pay up to $Y. Accordingly, the gateway 102 may, for example, sort the content options by time of availability and then rank, by price, those options that are available within the next 24 hours. These examples of user-specified criteria are only examples for illustration. In practice, a user could specify any qualitative and/or quantitative value, or range of values, for the criteria by which the content options are ranked.
In an embodiment of the invention, the options for receiving particular content may be ranked based on how well the characteristics of the options fit with the attributes and/or capabilities of a device or devices 104 via which the content will be consumed. For example, in instances that content is to be delivered to a home theater with a high-definition display and surround sound, the gateway 102 may, for example, rank the options from highest quality content to lowest quality content. Conversely, in instances that content is to be delivered to a handheld device, the gateway 102 may sort the content options by resolution and then, for the content options matching the resolution of the handheld device, sort them by cost and/or time of availability.
In some instances, the selected option may provide for pay-as-you-go, or per-download, or per-access payment. In such instances, the gateway 102 may pay for the content and then download or stream the content.
In some instances, the selected option may be from a subscription-based provider. In such instances, the gateway 102 may be operable to negotiate and/or enter into an agreement, a “micro-lease,” that provides for a subscription that is limited in scope and/or duration relative to the subscriptions that the provider usually offers. In an embodiment of the invention, micro-leases may be utilized in lieu of, and/or in conjunction with service level agreements (SLAs) to enable controlling and/or modifying service performance parameters based on actual needs and/or requirements. In this regard, a SLA may comprise a fixed, non-adjustable service contract with long duration, such as one or more years, whereas a micro-lease may comprise a dynamically established service contract, for much shorter durations, such as on hourly, daily, or weekly basis, with negotiable performance requirements, such as latency and/or quality of service, which are only applicable to these shorter durations. Accordingly, instead of being bound by a long standing SLA, which is configured in a fixed manner based on, and/or guaranteeing maximum possible performance requirements, subscribers may configure and/or utilize micro-leases only when services are actually needed, for only the actually required duration, and/or only based on actually needed performance requirements. Accordingly, the broadband gateway 102 may configure different micro-leases for the managed services based on determined actual needs and/or limitations. In this regard, the broadband gateway 102 may establish the micro-leases based on negotiating with the service providers. The negotiations may apply to such parameters as transmission bitrates, time of delivery, and/or quality of service, and/or apportionment and/or characteristics of content in instances where the request may comprise obtaining content. For example, a cable television provider may typically provide content on a monthly or yearly subscription basis, but the gateway 102 may be operable to negotiate a micro-lease for shorter amount of time and/or for specific content.
The broadband gateway 102 may communicate with the various devices via a home network that may comprise wired, optical, and/or wireless communication links, such as the home network 100a. In this regard, the broadband gateway 102 may comprise suitable hardware and/or software to provide some or all of the functions and/or operations of one or more of a modem, a router, and a switch. The modem functions and/or operations may be those of a digital subscribed line (DSL) modem, a cable modem, and/or a wireless cable modem, for example. The router functions and/or operations may be those of a wireless router, for example. The switch functions and/or operations may be those of a network switch, or a local area network (LAN) switch, for example. In some instances, the broadband gateway 102 may communicate with the various devices in the home via more than one home network.

The broadband gateway 102 may be operable to utilize client or home device profile information to select layered video service(s) and/or transmission. Such information may be stored, at least temporarily, in the memory module 206 of the broadband gateway 102. In some instances, the programming and/or enhanced video layers received by the broadband gateway 102 may be aggregated midstream by one or more network or routing nodes.
The broadband gateway 102 may support a reduction in the cost of unwatched content by using multi-tier billing for downloaded content, such as video content. The broadband gateway 102 may be utilized to provide a unified payment portal for collecting and/or aggregating charges from multiple service and/or content providers.
In operation, the gateway 102 may request and receive content from one or more providers via the provider interface module 202 and the one or more physical layer connections 1081-108j. The content may be requested and received from a network access provider such as a cable or satellite company and/or may be requested from content provider such as YouTube, Hulu, or a broadcasting network and received via the physical layer connection(s) 108 provided by a network access service provider. In some instances, different options for receiving particular content may be available via different ones of the physical layer connections 1081-108j. Content received via the interface 202 may be stored to the memory module 206 and/or to other local storage such as a digital video recorder (DVR) communicatively coupled to the interface 208. The processor module 204 may transcode and/or otherwise process content upon receiving it and/or upon outputting it to one or more devices 104 via the interface 208.
Upon determining that content is to be delivered to one or more devices 104 via the interface 208, the processor module 204 may trigger a search, via the interface 202, of available options for the content. Upon discovering the various options for receiving the content, the processor 204 may rank the options and select the highest-ranked option to acquire the content.
In operation, upon determining that particular content is to be delivered to a device 304, the gateway 102 may search out options for acquiring the particular content. The gateway 102 may query, for example, a search engine and/or send individual queries to each of one or more providers 3021-302N. The discovered options for acquiring the particular content may be stored in a table 306 with each of the entries 3071-307p, where P is any positive integer, corresponding to a different option. Each entry 307p, where p is an integer between 1 and P, may store characteristics of the corresponding option. In an embodiment of the invention, each entry 307p may comprise a field that indicates the provider associated with the option, a field that indicates quality of service associated with the option, a field that indicates power consumption associated with the option, a field that indicates when the option is available, and a field that indicates the price of the option.
The gateway 102 may also discover the devices 3041-304m, where M is any positive integer, to which it is communicatively coupled and the attributes of those devices. The attributes may be stored in a table 308 with each entry 309m, where m is an integer between 1 and M, comprising the attributes of the corresponding device 302m. Attributes of the devices may comprise, for example, display resolution, number of audio channels supported, supported encoding and decoding techniques, bandwidth of a connection between the device and the gateway 102, and whether the device is operating on battery power and/or in a low power mode.
The gateway 102 may also store a table 310 of user criteria for ranking and selecting content options. In an embodiment of the invention, the table 310 may comprise an entry 3111 which comprises power consumption criteria. Power consumption criteria may indicate, for example, whether saving power is important in deciding between options for receiving particular content. In an embodiment of the invention, the table 310 may comprise an entry 3112 which comprises quality of service (QoS) criteria. Quality of service criteria may indicate, for example, latency that is acceptable and/or error rates that are acceptable. Exemplary error rates may comprise bit error rates, packet error rates and/or frame error rates. In an embodiment of the invention, the table 310 may comprise an entry 3113 which comprises criteria that indicates when content may be available. Availability criteria may indicate, for example, whether the content is desired as soon as possible or whether the user is willing to wait in order to get a lower price. In an embodiment of the invention, the table 310 may comprise an entry 3114 which comprises criteria for the price of content. Pricing criteria may indicate, for example, how much the user is willing to pay for particular content or types of content. In an embodiment of the invention, the table 310 may comprise an entry 3115 which comprises criteria for which providers are utilized for obtaining content. Provider criteria may indicate, for example, a user's preferred provider(s).
In step 404, a user may enter and/or update criteria for ranking and selecting content options. Subsequent to step 404, the exemplary steps may advance to step 406 or to step 408 depending on various circumstances such as what the previous criteria were, what the new criteria are, and what content is scheduled for delivery via the gateway 102.
In step 406, the gateway 102 may search for options to receive scheduled content. The search may comprise, for example, querying various providers and/or a search engine designed to search for content provided via not only public networks such as the Internet, but also private networks such as cable television or satellite networks. In an embodiment of the invention, a first one or more options may be discovered via a first physical layer connection 1081 and one or more options may be discovered via a second physical layer connection 1082. For example, the first physical layer connection 1081 may be a DSL connection to the Internet and the second physical layer connection 1082 may be a DOCSIS connection to a cable provider. Accordingly, the gateway 102 may discover the content available via the Internet and may discover the content available from the cable provider.
In step 408, the gateway 102 may rank the content options that were discovered in step 406. An exemplary ranking technique is described with regard to
Additionally or alternatively, in step 414, the gateway may determine whether the received content is compatible with user-specified criteria. For example, the content may have been downloaded based on a first set of criteria but the criteria may have since changed. As a result, the content may be transcoded to make it compatible, or more compatible, with the newer criteria. In an embodiment of the invention, the content may be transcoded to meet quality criteria. For example, the resolution, frame rate, and/or amount of compression may be adjusted to meet user-specified criteria. In an embodiment of the invention, the content may be transcoded to meet power consumption criteria. For example, the content may be transcoded into a format that requires less energy to deliver over a network and/or to present on a device 304.
In instances that the received content is not compatible with the destination device(s) 304 and/or the user-specified criteria, the exemplary steps may advance to step 416 and the gateway 102 may transcode, reformat, and/or otherwise process the content to make it compatible or otherwise suitable for processing and/or consumption by the destination device(s) 304. For example, the resolution of the content may be scaled, have its frame rate adjusted, compressed, decompressed, decoded, and/or encoded. In instances that the received content is compatible with the destination device(s) 304 and the user-specified criteria, the exemplary steps may skip step 416 and advance to step 418. In step 418, the gateway 102 may deliver the content to the destination device(s) 304.
In step 706, the gateway 102 may assign one or more coefficients to one or more of the characteristics of the content option. In an embodiment of the invention, the option may be assigned a quality coefficient, a time coefficient, a price coefficient, a provider coefficient, and power coefficient.
In step 708, the gateway 102 may weight, that is, scale or adjust, the plurality of assigned coefficients by a corresponding plurality of weighting factors. The weighting factors may be determined based on, for example, user-specified criteria and/or on the attributes of the devices to which the content is to be delivered. Accordingly, the weighting factors may change as the user criteria and/or device attributes change. Furthermore, upon a change in one or more weighting factors, discovered options may be re-ranked. In an embodiment of the invention, the gateway 102 may determine a quality weighting factor, a time weighting factor, a price weighting factor, a provider weighting factor, and power weighting factor. For example, in instances that a user wants the lowest-cost option available, the price weighting factor may be set to a high value and the other weighting factors may be set to lower values. For another example, in instances that a device supports only standard-definition video, the quality weighting factor may be set to a low value and the other factors may be set to higher values.
In step 710, the weighted coefficients of the option may be summed together resulting in a score for the option. In step 712, the option and other options for the particular content may be ranked based on their respective scores.
Various aspects of a method and system for customized acquisition of content by a broadband gateway are provided. In an exemplary embodiment of the invention, a broadband gateway 102 may be operable to determine options for acquiring particular content. The broadband gateway 102 may be operable to rank the determined options. The ranking may be based on one or more characteristics of the options and based on user-specified criteria. The broadband gateway 102 may be operable to select one of the options for acquiring the content based on results of the ranking. The broadband gateway 102 may support a plurality of physical layer connections 108 to a corresponding plurality of network access service providers 120. One or more of the options may be available via a first one of the plurality of physical layer connections 1081-108j and one or more of the options may be available via a second one of the plurality of physical layer connections 1081-108j. The one or more characteristics may comprise a provider associated with each of the options, a time of availability of each of the options, a quality of the particular content associated with each of the options, a power consumption associated with each of the options, and/or a price associated with each of the options.
The user specified criteria may comprise one or more of: criteria for selecting between the options based on providers associated with the options, criteria for selecting between the options based on a time at which each of the options can be acquired, criteria for selecting between the options based on quality of a version of the particular content associated with each of the options, criteria for selecting between the options based on power consumption associated with acquiring and consuming the content, and criteria for selecting between the options based on a price associated with each of the options. The user-specified criteria may be stored in memory in the broadband gateway 102. The gateway 102 may rank the determined options based on attributes of one or more devices 304 via which the particular content will be consumed. The attributes may comprise one or more of: a display resolution of the one or more devices 304, a decoding technique supported by the one or more devices 304, and a bandwidth of a connection 106 between the one or more devices 304 and the broadband gateway. The attributes may be stored in memory in the broadband gateway 304.
The broadband gateway 102 may be operable to generate a score for each one of the options and the options may be ranked based on the score. The score of an option may be generated by assigning one or more coefficients to the one or more characteristics of the options, scaling or weighting the one or more coefficients by one or more corresponding weighting factors, and summing the weighted coefficients. The weighting factors may be determined based on the user-specified criteria and/or on the attributes of devices via which the particular content is to be consumed.
