Title: Apparatus and method of acquiring or distributing content

Description:
CLAIM OF PRIORITY UNDER 35 U.S.C. §119 
     The present application for patent claims priority to Provisional Application No. 61/375,240 entitled “Apparatus and Method of Acquiring or Distributing Content” filed Aug. 20, 2010, and assigned to the assignee hereof and hereby expressly incorporated by reference herein. 
    
    
     BACKGROUND 
     The present disclosure relates generally to wireless communications, and more specifically to an apparatus and method of acquiring or distributing content via a wireless communication network. 
     Today&#39;s wireless Internet is a pull system, where the use model assumes that the device is always connected and the user then downloads whatever is needed. The problem with this model is that wireless communication, by virtue of its physics, is unpredictable. For example, there are places where a user may get good connectivity and other places where the user may get poor connectivity. Therefore, in the current wireless Internet pull system, it is hard to ensure that the user can get a consistent experience all over the geography where the user wants to access the Internet. 
     In addition, in the future, it is expected that wireless network carriers may place a premium price on accessing their WAN network services. 
     Thus, improvements in distributing or obtaining content via wireless communication links are desired.

     DETAILED DESCRIPTION 
     The present aspects include apparatus and methods of providing content to, or acquiring content at, a wireless device. With respect to content delivery, the described apparatus and methods, such as a network-based content delivery service, identify types of available wireless communication links, such as based on a cost of using the respective link. Further, the described aspects then select one or more content items for distribution over the link or links based on a distribution rule. For example, the distribution rule may prioritize the content according to a prioritization code, such as value or fee received for distributing the content, and this priority may vary depending on the type of the communication link. With respect to content acquisition, a wireless communication device, such as a cellular phone or other similar device, may identify that the above-noted prioritized content is available for receipt, and then determine whether to download one or more of the prioritized content. For example, the wireless device may apply an acquisition rule to the available prioritized content to identify one or more content items that are suitable for downloading, such as based on matching an interest of the user of the wireless device. Thus, the described aspects and methods provide a push system for content distribution that efficiently utilizes selected wireless links and then efficiently prioritizes a sequence of content for distribution over those links, allowing a wireless device to further selectively download such content. 
     In an aspect, the described apparatus and methods include a smart download manager. For example, in an aspect, the smart download manager knows the cost associated with each of the networks that the device connects with, and downloads content in a least costly way. In one case, for example, content items may be downloaded when the wireless device is on a free WiFi network. In another aspect, updates to content items during the day may come by the way of a low cost broadcast network, or through low cost, short range networks, such as Femto cells. In other words, the described apparatus and methods prioritize the delivery of content over different connections and create a better and a cheaper connectivity solution for the user of the wireless device. 
     More specifically, the system has a smart server, e.g. the content delivery service, and a smart client, e.g. the download manager. In an aspect, the smart server prioritizes delivery of content items based on a pricing system. For example, content providers that pay more get to have their content item(s) go first in a prioritized sequence of one or more content items. Further, there may be a class of content item prioritization that allows a content item to be distributed in real-time, such as on a network like a 3G scavenger class network. Additionally, in an aspect, the smart client or download manager prioritizes acquisition of content items about which the user cares, such as based on a user profile. Accordingly, in an aspect, the download manager may include a download rule, also referred to as a content acquisition rule, that compares a content characteristic to a device user preference and identifies a match. So, for example, the smart client or download manager may first download content items that user likes to consume rather than content items that the content delivery service prioritizes. In other aspects, from the point of view of a content provider, the system may appear like a file syncing system, as files put on the server are delivered to the wireless device in a push manner. For instance, file syncing can be round robin with proportional fair scheduling wherein the weights are derived from an allocation file. In an exemplary aspect, the default priority of delivery is specified on the server. If the device consumes some content or if the user specifies a priority on the device then that priority can supersede that specified by the server. 
     Thus, in an aspect, the described apparatus and methods deliver all or some portion of content items, in a prioritized sequence, to one or more wireless devices via free or low cost communication links, thereby avoiding more costly WAN networks, such as 3G networks. 
     Referring to  FIG. 1 , in an aspect, a content delivery or acquisition system  10  includes a content delivery service  12 , such as may be hosted by a network-based media server, having a distribution manager  14  that executes one or more distribution rules  16  to distribute a prioritized sequence  18  of one or more content items  20  to one or more wireless devices  22 . Specifically, the one or more distribution rules  16  control content distribution according to a type  24  of one or more available communication links  26  between content delivery service  12  and a respective wireless device  22  and according to a prioritization code  28  corresponding to each content item  20 . Thus, content delivery service  12  is able to push, in an ordered manner, one or more content items  20  to one or more wireless devices  22 . 
     Content item  20  may include, but is not limited to, one or more types of information such as audio, video, text, a graphic, haptic information, a web page, a song, a movie, a book, and other similar electronic data that may be presented to or consumed by a user of wireless device  22 . In addition, content item  20  can comprise media content and application content. 
     The term application as used herein refers to computer software program in general and can further encompass data, configuration settings, etc., used by the computer software program. Examples include utilities such as e-mail, Short Message Service (SMS) text utility, chat interface, web browsers, calculators, viewers, media players, games, etc. In an exemplary aspect, application can refer to software that is suitable for use on a mobile device, especially to being downloaded via a Wireless Local Access Network (WLAN) or Wireless Wide Area Network (WWAN). 
     Further, for example, the type  24  of the one or more available communication links  26  may relate to one or more communication link parameters, such as but not limited to a technology type (e.g. WiFi, WiMax, cellular, etc.), a cost of use of the link (e.g., free, cost per minute, cost per amount of data transmitted, etc.), a speed of the link, an available bandwidth of the link, or any other characteristic that defines the link or an operational attribute of the link. In an aspect, for example, the one or more distribution rules  16  may define a hierarchy or ordered list or ranking of a plurality of types  24  of communication links  26 . In one case, for example, the one or more distribution rules  16  may rank distribution of content via a free communication link as being preferable to distribution over a fee-based communication link. Additionally, for example, prioritization code  28  may include, but is not limited to, a value or identifier that provides a measure of relative priority to enable content item priorities to be compared to rank or order each content item  20  to define prioritized sequence  18 . In an aspect, each prioritization code  28  may correspond to a value associated with the corresponding content item  20 , where the value may be based on, for example, a payment to be received or already received for distribution of the corresponding content item  20 . In one instance, for example, the payment may be based on a winning bid of a content provider for a placement of the content item in a given relative position within prioritized sequence  18 . Further, for example, in an aspect, one or more distribution rules  16  may define prioritized sequence  18  by comparing and ranking the respective prioritization code  28  of each of a plurality of content items  20  that are available for distribution. Further, for example, distribution manager  14  may generate a same, or a different, prioritized sequence  18  of content items  20  for distribution for each type  24  of the one or more communication links  26 . For instance, a first prioritized sequence of content items corresponding to a first type of communication link may differ from a second prioritized sequence of content items corresponding to a second type of communication link, where the difference may include one or more of the specific content items included in the respective prioritized sequence, or an order of the specific content items included in the respective prioritized sequence, or both. 
     Moreover, in an aspect that may work independently from or in conjunction with content delivery service  12 , each wireless device  22  may include a download manager  30  that executes one or more acquisition rules  32  to control the acquisition and storage of content items  20  by the wireless device  22 , such as in a memory  31 . In particular, the one or more acquisition rules  32  control content acquisition according to one or more factors, such as but not limited to one or more of a user preference  34 , a device parameter  36  such as available memory or available power, a content item parameter  38  such as a format or type of the content item (e.g. video, music, etc.), the type  24  of the one or more communication links  26 , or any other user-specific, device-specific, content-specific, or communication link-specific attribute that may influence whether a particular content item is to be downloaded at a given instance. 
     Further, each wireless device  22  may further include a memory  40  for storing one or more downloaded content items  20 , as well as a user interface media manager  42  for controlling presentation or acquisition of one or more content items  20  on wireless device  22 . 
     Optionally, in an aspect, acquisition system  10  may further include a deposit manager  44 , such as part of or in communication with content delivery service  12 , to control obtaining one or more content items  20  from one or more content providers  46  for subsequent distribution by distribution manager  14 . In an aspect, for example, content delivery service  12  includes a memory  49  that stores one or more content items  20  received from one or more content providers  46  according to one or more deposit rules  48 . Deposit rules  48  may include, but are not limited to, one or more rules or factors that define one or more of a type of content, a recommended user age or maturity rating or code that identifies an intended audience for the content, an approved content provider, or any other attribute that may be used to determine if a content item  20  is acceptable to be received by and distributed within acquisition system  10 . 
     Thus, acquisition system  10  provides content delivery service  12  that distributes, or one or more wireless devices  22  that acquire, one or more content items  20  in a push manner, which may improve efficiency in communications, at the content distribution service, or at the wireless device, by basing the push of content on one or more distribution rules  16  that control content distribution according to a type  24  of one or more available communication links  26  between content delivery service  12  and a respective wireless device  22  and according to a prioritization code  28  corresponding to each content item  20 . Hence, the described aspects provide apparatus and methods that execute to distribute a prioritized sequence  18  of one or more content items  20 . 
     Referring to  FIG. 2 , in an aspect, content delivery service  12  may include or be implemented on any type of computer device, such as a network server. Content delivery service  12  includes a processor  50  for carrying out processing functions associated with one or more of components and functions of content delivery service  12  described herein. Processor  50  can include a single or multiple set of processors or multi-core processors. Moreover, processor  50  can be implemented as an integrated processing system or a distributed processing system. 
     Content delivery service  12  further includes memory  49 , as mentioned above, such as for storing local versions of applications being executed by processor  50 . Memory  49  can include any type of memory usable by a computer, such as random access memory (RAM), read only memory (ROM), tapes, magnetic discs, optical discs, volatile memory, non-volatile memory, and any combination thereof. 
     Further, content delivery service  12  includes a communications component  54  that provides for establishing and maintaining communications with one or more parties utilizing one or more of hardware, software, or services as described herein. Communications component  54  may carry communications between components on content delivery service  12 , as well as between content delivery service  12  and external devices, such as devices located across a communications network, or devices serially or locally connected to content delivery service  12 . For example, communications component  54  may include one or more buses, and may further include transmit chain components and receive chain components associated with a transmitter and receiver, respectively, or a transceiver, operable for interfacing with external devices. Further, for example, communications component  54  may include one or more communication interfaces, where each communication interface can establish and manage at least one communication link  26  ( FIG. 1 ) with one or more wireless devices  22  ( FIG. 1 ). 
     Additionally, content delivery service  12  may further include a data store  56 , which can be any suitable one or combination of hardware or software, that provides for mass storage of information, databases, applications and programs employed in connection with aspects described herein. For example, data store  56  may be a data repository for applications not currently being executed by processor  50 . 
     Content delivery service  12  may additionally include a user interface component  58  operable to receive inputs from a user of content delivery service  12 , and further operable to generate outputs for presentation to the user. User interface component  58  may include one or more input devices, including but not limited to a keyboard, a number pad, a mouse, a touch-sensitive display, a navigation key, a function key, a microphone, a voice recognition component, or any other mechanism capable of receiving an input from a user, or any combination thereof. Further, user interface component  58  may include one or more output devices, including but not limited to a display, a speaker, a haptic feedback mechanism, a printer, or any other mechanism capable of presenting an output to a user, or any combination thereof. 
     Further, as discussed with respect to  FIG. 1 , content delivery service  12  includes deposit manager  44  that obtains content items  20  from content providers  46  according to one or more deposit rules  48 . 
     Also, as discussed with respect to  FIG. 1 , content delivery service  12  includes one or more content items  20 , each having a corresponding prioritization code  28 . Each content item  20  may optionally include one or more content type data  60 , such as metadata that identifies the content, provides a description or definition of the content, defines a format of the content, or any other data useful in managing or acquiring of the corresponding content item. 
     In an aspect, content delivery service  12  maintains the one or more content items  20  in one or more directories, enabling content delivery service  12  to function as a directory syncing system. For example, in an aspect, the directory structure at content delivery service  12  may be replicated on one or more wireless devices  22 . Alternatively, there may be a set of rules executed by content delivery service  12  to dictate where each content item  20  is to be stored on one or more wireless devices  22 . For example, content delivery service  12  may provide a directory identifier with each content item  20  to control which directory in the wireless device  22  to store each content item  20 . As such, an application on the wireless device that is interested in using the content item only has to search a known directory, as opposed to searching the entire wireless device, to find the content item of interest to the application. In another aspect, if a content item  20  is removed from content delivery service  12 , then the syncing functionality also initiates removal of the corresponding content item  20  from each wireless device  22 , for example, by transmitting a removal code corresponding to each content item  20  to be removed. 
     Additionally, as discussed with respect to  FIG. 1 , content delivery service  12  includes distribution manager  14  that distributes prioritized sequence  18  of one or more content items  20  according to one or more distribution rules  16 . In an aspect, distribution manager  14  may further include a connection evaluator component  62  that determines, at any given time, the available communication links  26  ( FIG. 1 ) and their corresponding types  24  ( FIG. 1 ). For example, connection evaluator component  62  may communicate with communications component  54  to determine this information. Further, for example, connection evaluator component  62  may consult a local or remote database to acquire the information to define the type  24  of each available communication link  26 . As such, distribution manager  14  consults with connection evaluator component  62  to determine prioritized sequence  18  of one or more content items  20  based, at least in part, on the type  24  of each available communication link  26 . 
     Moreover, in an aspect, distribution manager  14  may generate or obtain an available content list  66  that identifies the plurality of content items  20  that are available from distribution manager  14 . Distribution manager  14  may periodically distribute available content list  66  to the one or more wireless devices  22 . For example, distribution manager  14  may transmit available content list  66  over one or more communication links  26  so that each wireless device  22  may provide a user with an ability to select desired ones of the available content items  20  to acquire. 
     Referring to  FIG. 3 , in an aspect, wireless device  22  includes any type of computer device, such as a cellular phone, a personal data device, a mobile gaming device, etc. Wireless device  22  includes a processor  67  for carrying out processing functions associated with one or more of components and functions described herein.

     Further, as discussed with respect to  FIG. 1 , wireless device  22  includes a download manager  30  that downloads one or more content items  20  via one or more wireless communication links  26  according to one or more acquisition rules  32 . For example, the one or more acquisition rules  32  may obtain information, such as a user preference  34  from a user profile  76 , or a device parameter  36 , such as available storage space  78  or available power  80 , or the type  24  each available communication link  26  and analyze this information in order to determine whether to download a respective content item  20 . For example, the one or more acquisition rules  32  may dictate to only download content items  20  that match a user preference  34 , or that match a device parameter  36 , or that are downloadable over a specific one of the types  24  of available wireless communication links  26 . 
     In another aspect, user profile  76  may additionally include subscription information  82 , such as identifiers, keys, etc., that enable wireless device  22  to acquire one or more content items  20  from content delivery service  12 . 
     Additionally, in an aspect, wireless device  22  may further include user interface media manager  42 , as mentioned above, which allows user interaction to control acquisition and presentation of one or more content items  20 . 
     Referring to  FIG. 4 , in an aspect, a method  90  of distributing content, such as by a content delivery service, comprises identifying a type of at least one available wireless communication link (Block  92 ). For example, in one non-limiting aspect, connection evaluator component  62  ( FIG. 2 ) may consult with communications component  54  to determine each type  24  of one or more available wireless communication links  26  ( FIG. 1 ). 
     The method  90  further includes selecting at least one content for distribution based on a distribution rule that prioritizes the distribution of the content according to a prioritization code corresponding to the content and according to the type of the at least one available wireless communication link (Block  94 ). For example, in one non-limiting aspect, distribution manager  14  may execute one or more distribution rules  16  to generate prioritized sequence  18  of one or more content items  20  based on their respective prioritization code  28  and based on the type  24  of the one or more available wireless communication links  26  ( FIG. 1 ). 
     For example, in an aspect, the at least one available wireless communication link comprises one of a plurality of available wireless communication links each having a corresponding type, wherein each type includes a cost parameter, and the selecting comprises selecting the at least one available wireless communication link from the plurality of available wireless communication links according to a corresponding cost parameter. 
     In another aspect, the at least one content comprises one of a plurality of content for distribution, and the selecting further comprises selecting a second one of the plurality of content for distribution on a second one of the plurality of available wireless communication links based on a respective prioritization code corresponding to the second one of the plurality of content and according to a respective type of the second one of the plurality of available wireless communication links. 
     In a further aspect, wherein the at least one content comprises one of a plurality of content for distribution, the selecting further comprises selecting each of the plurality of content for distribution in a specific order on the at least one available wireless communication link based on a respective prioritization code corresponding to each of the plurality of content. 
     In yet another aspect, the selecting may further include determining not to distribute a second one of the plurality of content on any of the plurality of available wireless communication links based on a respective prioritization code corresponding to the second one of the plurality of content and according to each type of the plurality of available wireless communication links. 
     Also, the method  90  further includes distributing the at least one content via the at least one available wireless communication link (Block  96 ). For example, in one non-limiting aspect, distribution manager  14  transmits prioritized sequence  18  of one or more content items  20  over the one or more available wireless communication links  26 . 
     Referring to  FIG. 5 , in an aspect, a method  110  of acquiring content, such as may be executed by a mobile device, comprises identifying a presence of content to download via at least one wireless interface (Block  112 ), wherein the content to download is available via the at least one wireless interface based on a distribution rule that prioritizes a distribution of the content according to a prioritization code and according to a type of a wireless communication link corresponding to the at least one wireless interface. For example, in one non-limiting aspect, on wireless device  22  ( FIG. 4 ), download manager  30  may consult with communications component  70  to determine available ones of one or more wireless communication links  26 . Further, download manager  30  may monitor communication links  26  for transmissions of prioritized sequence  18  of one or more content items  20  from content delivery service  12  ( FIG. 1 ). 
     The method  110  further includes determining to download the content via the at least one wireless interface (Block  114 ). For example, in one non-limiting aspect, download manager  30  executes one or more acquisition rules  32  to compare parameters of the content items or links with user preferences or device capabilities in order to find matches that indicate a content item is suitable for downloading. 
     Also, the method  110  includes downloading the content via the at least one wireless interface (Block  116 ). For example, in one non-limiting aspect, download manager  30  initiates the receiving and storage of one or more content items  20 , such as in memory  40  of wireless device  22 . As such, the stored content items are then subsequently available for presentation to a user of the wireless device  22 . In another aspect, download manager  30  may receive a content index that identifies the content, receive a user selection of the content from the content index, and retrieve the content from a memory on a device if the content is stored in the memory, or download manager  30  may initiate downloading of the content if the content is not stored in the memory. 
     Referring to  FIG. 6 , in an aspect, an apparatus  130  that receives and distributes content items may reside at least partially within a network component, such as a network server. It is to be appreciated that apparatus  130  is represented as including functional blocks, which can be functional blocks that represent functions implemented by a processor, software, or combination thereof (e.g., firmware). Apparatus  130  includes a logical grouping  132  of electrical components that can act in conjunction. For instance, logical grouping  132  can include a module or electrical component  134  for identifying a type of at least one available wireless communication link. 
     Further, logical grouping  132  can comprise a module or electrical component  136  for selecting at least one content for distribution based on a distribution rule that prioritizes the distribution of the content according to a prioritization code corresponding to the content and according to the type of the at least one available wireless communication link. Furthermore, logical grouping  132  can comprise a module or electrical component  138  for distributing the at least one content via the at least one available wireless communication link. 
     Additionally, apparatus  130  can include a memory  140  that retains instructions for executing functions associated with electrical components  134 ,  136 , and  138 . While shown as being external to memory  140 , it is to be understood that one or more of electrical components  134 ,  136 , and  138  can exist within memory  140 . 
     Referring to  FIG. 6 , in an aspect, an apparatus  150  that acquires and presents content items may reside at least partially within mobile device, such as a wireless communication device. It is to be appreciated that apparatus  150  is represented as including functional blocks, which can be functional blocks that represent functions implemented by a processor, software, or combination thereof (e.g., firmware). Apparatus  150  includes a logical grouping  152  of electrical components that can act in conjunction. For instance, logical grouping  152  can include a module or electrical component  154  for identifying a presence of content to download via at least one wireless interface, wherein the content to download is available via the at least one wireless interface based on a distribution rule that prioritizes a distribution of the content according to a prioritization code and according to a type of a wireless communication link corresponding to the at least one wireless interface. 
     Further, logical grouping  152  can comprise a module or electrical component  156  for determining to download the content via the at least one wireless interface. Furthermore, logical grouping  152  can comprise a module or electrical component  158  for downloading the content via the at least one wireless interface. 
     Additionally, apparatus  150  can include a memory  160  that retains instructions for executing functions associated with electrical components  154 ,  156 , and  158 . While shown as being external to memory  160 , it is to be understood that one or more of electrical components  154 ,  156 , and  158  can exist within memory  160 . 
     As previously described with regard to  FIG. 1 , prioritization by the content delivery system  12  can be made in accordance with one or more factors, such as storage space  78 , power  80 , user preferences  34 , and type of communication link  26 . It should be appreciated with the benefit of the present disclosure that the content delivery system  12  can dynamically address interruptions in distribution as well as other changes in the afore-mentioned factors as well as others. In particular, prioritization of distribution of content can depend on one or more factors including (a) user interest; (b) subscription status; (c) channel cost; and (d) device limitation(s) (e.g., memory storage, battery service life, etc.). Also as previously disclosed, in an exemplary aspect mass distribution (e.g., one-to-many transmission) can be employed for network efficiency to mobile devices that cache content items. It is contemplated that partial delivery warranted by network considerations, device limitations, or user preferences, can be followed by completion of delivery when priority for a content item changes. In particular, one of several delivery channels can be employed to optimize the delivery from the point of the view of a mobile device or the network. 
     For example, a broadcast channel or cellular multi-cast can be used. A secondary transmission for completing distribution of a content item can be employed for mobile devices that did not receive the entire content item. For instance, the secondary transmission can be another one-to-many transmission, in particular a chain reaction encoded (described below) portion of the content item, to avoid having to fully re-transmit the content item. Alternatively or in addition, the secondary transmission can be an unlocking component (e.g., subscription code, data rights management authentication, etc.). Alternatively or in addition, the secondary transmission can be a one-to-one re-transmission to satisfy the needs of a particular mobile device, such as deferred until a low cost type of link is available (e.g., WiFi). 
     In one aspect, distribution that is responsive to user patterning and consumption can further be responsive to selective or changing circumstances as to one or more paths that can be used to complete distribution, in either a one-to-many (e.g., broadcast, multicast) or unicast fashion, to one or more devices. For instance, delivering via a broadcast at least in part can be an efficient approach from a perspective of a network for content distribution. Going through multiple networks and delivering ad hoc from devices that are proximate to a device (e.g., creating a location to an extent) can be coupled with this network efficiency to ensure that individual needs are satisfied without an undue burden to the network. 
     Coupling the needs for mass distribution while satisfying individual prioritization can be achieved in an exemplary aspect by use of encoding that allows less message traffic and individualized retransmissions. To that end, the present disclosure provides for decoding information additive codes and multi-stage information additive codes, herein referred to collectively as “chain reaction codes.” 
     Chain reaction codes have been described previously in the assignee&#39;s patents, such as U.S. Pat. No. 6,307,487 entitled “Information Additive Code Generator and Decoder for Communication Systems”, and U.S. Pat. No. 7,068,729, entitled “Multi-Stage Code Generator and Decoder for Communication Systems” (hereinafter “Raptor”). As described therein, chain reaction decoding is a unique form of Forward Error-Correction (FEC) that enables data reconstruction from a received data set of a given size, without regard to the particular data packets received. Communication systems employing chain reaction codes are able to communicate information much more efficiently compared to traditional FEC codes transmitted via data carousel or acknowledgement-based protocols, as described in Luby I or Raptor, as provided below. 
     In an exemplary aspect, Raptor encoding provides a method of encoding data for transmission from a source to a destination over a communications channel. A plurality of redundant symbols are generated from an ordered set of input symbols to be transmitted. A plurality of output symbols are generated from a combined set of symbols including the input symbols and the redundant symbols. The number of possible output symbols is much larger than the number of symbols in the combined set of symbols. Furthermore, at least one output symbol is generated from more than one symbol in the combined set of symbols and from less than all of the symbols in the combined set of symbols, such that the ordered set of input symbols can be regenerated to a desired degree of accuracy from any predetermined number, N, of the output symbols. 
     Returning to the Drawings, in  FIG. 8  a content distribution system  200  operates on a communication network  202  to distribute content items  204  to a population of communication devices  205 , which can comprise mobile devices  206 . As part of the communication network  202 , an apparatus  208  for distributing content comprises an encoder  210  for chain reaction encoding of a content item  204 . A transmitter  212  transmits the content item  204  as encoded packets  214  via a one-to-many transmission  216  (e.g., broadcast, cellular multi-cast, etc.) from a first link  218  to the population of mobile devices  206 . A network interface  220  retransmits at least a portion  221  of the content item  204  as encoded packets  222  via a second transmission  223 , which can be a one-to-many or one-to-one transmission. The network interface  220  can determine what portion to retransmit based upon feedback  224  received from at least a subset of the population of mobile devices  206 . 
     In an exemplary aspect, the encoder  210  of the apparatus  208  may be a chain reaction encoder (e.g., Raptor code) to more efficiently broadcast or multi-cast the content items  204  in situations in which the reception can be lossy or mobile devices  206  may be temporarily out of service or otherwise inactive. A content provider  228  can specify a directory structure  230  that is conveyed with the content item  204 . 
     The content distribution system  200  can encompass or interface with a subscription or purchasing system  232  that tracks subscribers  234  or data management rights  236  for content items  204  and provides an unlocking component  238  (e.g., subscription code, decryption key, etc.). 
     The second transmission  223  can utilize the same access technology as the first one-to-many transmission  216 . Alternatively or in addition, a mobile device  206  can utilize a second type of link, depicted first as an access point  240  (e.g., WLAN) that can provide cost efficient data throughput. Alternatively or in addition, the mobile device  206  can utilize a cellular network  242 . 
     One of the mobile devices  206  is depicted as including an apparatus  244  for acquiring a content item  204  by using a receiver  246  for receiving a first portion  248  of the content item  204  from a first link, depicted as the one-to-many transmission  216 . A computing platform  249  detects a triggering event  250  for the content item  204 . The receiver  252  further accesses a second portion  254  of the content item  204  via a second transmission, depicted as either the second transmission  223 , the unlocking component  238 , access point  240 , or cellular network  242 . For example, the device may be operable for receiving a first portion of a content item and subsequently receiving the second portion of a content item. For example, the subsequent receiving of the second portion of the content item may be based on initially failing to receive the second portion of the content item via the one-to-many transmission of the content item, or the subsequent receiving of the second portion of the content item may be based on deferring storage of the second portion of a content item due to prioritization of the content item. 
     In an exemplary aspect, the apparatus  244  for acquiring content can utilize a decoder  256  for chain reaction decoding (e.g., Raptor code). For example, different mobile devices  206  can each receive a different portion of the content item  204 , as depicted at  258 - 260 . Without necessarily sending the exact same respective portions, receiving Raptor code encoded portion in proportion to the amount missed can complete the distribution of the content item  204 . 
     The computing platform  249  detects the triggering event  250  as a selected one or more of a number of factors. For instance, the trigger event  250  can be, at least in part, a user input  266  to a user interface  268  associated with the content item  204 . For another instance, the trigger event  250  can be, at least in part, a change in a device parameter associated with capacity to receive the content item  204  depicted as power level  270  and available storage  272 . For an additional instance, the trigger event  250  can be, at least in part, the availability of a subscription  274  for the content item  204 . For yet another instance, the trigger event  250  can be, at least in part, an availability of a type of link  276  for receiving the second portion  254  of the content item  204 . 
     To facilitate the user input  266 , the user interface  268  can be for indicating a status for accessibility of the content item  204  by displaying an annotation or icon for the content indicating a selected one of stored for use, pending access upon acquiring a selected type of link, and access pending user selection. For example, a first icon  278  indicates content item  204  that is fully available on the apparatus  244  for consumption or use (e.g., in a standalone mode). A second icon  280  indicates a content item  204  that is downloaded or cached but requires activation (e.g., acquiring license or subscription rights). A third icon  282  indicates a content item  204  that was partially downloaded and cached, requiring a second attempt or other link to complete such as from a second access network or node (e.g., Raptor coded retransmission). A fourth icon  284  indicates a content item  204  that was not cached due to a determined low priority but could be elevated in priority upon user selection. Alternatively, some of these categories of content icons can be accessed in a menu-driven, hierarchical or faceted search manner wherein a particular screen provides other groupings to indicate a status for download and use. 
     In use, a caching service can utilize content applications that are packaged as part of the operating system or provided by content providers. For instance, a content application can act as installer, looking to what content is locally stored first before pulling remote content to a mobile device. Alternatively or in addition, application installers would also be delivered to the device with the content. Applications or other content provisioned on the mobile device, distributed by a caching service, or retrieved by the content application or application installer can utilize a cellular or other remote link as well as a manual authorization code entry. Syncing can stop if there is no storage left on the mobile device or prioritization can be used to selectively overwrite existing content. 
     In an illustrative operational concept for a caching service, any data delivered to the server is delivered to a target directory on the mobile device which is specified by the content provider on the server. The caching service can sync up the server side content directory with the device side content directory. The content provider delivers the content to the server and this content is delivered seamlessly to the mobile device through one of several paths. Each path can have a distinct subscription cost and priority. For instance, a lower priority path is utilized if a higher priority path is not available or upon selection by the user to expedite delivery. Moreover, each path itself can comprise primary and secondary paths, etc., specified for use in the event of failure of a path. 
     The mobile device can track which cache directories are used by the user and then stop syncing those directories that are not used by the user to conserve memory storage and battery life or reduce a subscription cost. In addition the user can mark directories that should not be synced and directories that should be synced. Content that is already on the device will not be attempted to be synced. An index can be accessed by the user to see all of the content that is available for syncing. In some instances, content can be designated that should be deleted from a server for future syncing or that should be deleted from mobile devices. For instance, a subscription right to consume content can expire. The caching system can implement caching of content dependent upon receiving an indication from a connectivity application based on connection availability and business rules. For example, a business rule can limit caching to only when Wi-Fi is available. As another example, cellular access to caching can be limited to one-to-many broadcasting or multicasting with chain reaction coding employed for efficient retransmissions. 
     Each different content provider can have their login account that specifies the name of the directory that would be created on each mobile device as part of the caching system. The directory structure on the server could be replicated on the mobile device. The content provider can get statistical information (e.g., a histogram) regarding content distribution to a population of mobile devices. Thereby, the content providers can determine the success of the content distribution. 
     In  FIG. 9 , the present disclosure provides a methodology  300  for distributing content by chain reaction encoding (e.g., Raptor code) a content item (block  304 ). The methodology  300  further provides transmitting the content item as encoded packets via a one-to-many transmission from a first link to a population of mobile devices (block  306 ). The methodology  300  further provides retransmitting at least a portion of the content item as encoded packets via a second transmission (block  308 ). The retransmission can be a one-to-many transmission or a one-to-one transmission. The retransmission can be in response to determining that a subset of the population of mobile devices failed to receive the content item. The chain reaction encoding can indicate an intended destination directory for cache storage of the content item on each of the population of mobile devices. 
     Provisions can include integrating purchasing and subscription services. To that end, the methodology  300  can provide wherein retransmitting the at least the portion of the content item further comprises transmitting an unlocking component for the content item. In particular, transmitting the unlocking component for the content item can be achieved by accessing the unlocking component from a purchasing system and transmitting the second transmission from a cellular network. 
     In  FIG. 10 , the present disclosure provides a methodology  400  for acquiring content by receiving a first portion of a content item via a one-to-many transmission at a device from a first link (block  404 ). The methodology  400  further provides detecting a triggering event for the content item (block  406 ). The methodology  400  further provides accessing a second portion of the content item via a second transmission (block  408 ). The second portion can be accessed via a one-to-many or a one-to-one transmission. In an exemplary aspect, the first and second portions are sent with chain reaction encoding (e.g., Raptor code). 
     The triggering event for accessing the second portion of the content item can be at least one of a user input associated with the content item, a change in a device parameter associated with capacity to receive the content item, availability of a subscription for the content item, or availability of a type of link for receiving the second portion of the content item. 
     In order to receive the user input, a user interface can be provided for indicating a status for accessibility of the content item (e.g., displaying an annotation or icon for the content item indicating a selected one of stored for use, pending access upon acquiring a selected type of link, and access pending user selection). Further, the indications can be displayed representative for the first portion received and the second portion not received of the content item. For instance, a relatively small amount of the content item not accessed via a one-to-many transmission can warrant a one-to-one retransmission (e.g., cellular) whereas a large amount not yet accessed can warrant an alternative, deferred access (e.g., WiFi). 
     With reference to  FIG. 11 , illustrated is a system  500  for distributing content. For example, system  500  can reside at least partially within a network entity (e.g., evolved base node). It is to be appreciated that system  500  is represented as including functional blocks, which can be functional blocks that represent functions implemented by a computing platform, processor, software, or combination thereof (e.g., firmware). System  500  includes a logical grouping  502  of electrical components that can act in conjunction. For instance, logical grouping  502  can include an electrical component  504  for chain reaction encoding a content item. Moreover, logical grouping  502  can include an electrical component  506  for transmitting the content item as encoded via a one-to-many transmission from a first link to a population of mobile devices. Moreover, logical grouping  502  can include an electrical component  508  for retransmitting at least a portion of the content item as encoded via a second transmission. Additionally, system  500  can include a memory  520  that retains instructions for executing functions associated with electrical components  504 - 508 . While shown as being external to memory  520 , it is to be understood that one or more of electrical components  504 - 508  can exist within memory  520 . 
     With reference to  FIG. 12 , illustrated is a system  600  for acquiring content. For example, system  600  can reside at least partially within user equipment (UE) or mobile device. It is to be appreciated that system  600  is represented as including functional blocks, which can be functional blocks that represent functions implemented by a computing platform, processor, software, or combination thereof (e.g., firmware). System  600  includes a logical grouping  602  of electrical components that can act in conjunction. For instance, logical grouping  602  can include an electrical component  604  for receiving a first portion of a content item via a one-to-many transmission at a device from a first link. Moreover, logical grouping  602  can include an electrical component  606  for detecting a triggering event for the content item. In addition, logical grouping  602  can include an electrical component  608  for detecting a triggering event for the content item. Additionally, system  600  can include a memory  620  that retains instructions for executing functions associated with electrical components  604 - 608 . While shown as being external to memory  620 , it is to be understood that one or more of electrical components  604 - 608  can exist within memory  620 . 
     In  FIG. 13 , in a communication system  700 , an apparatus  702 , such as user equipment, a data processing system, a mobile device, etc., acquires network content  704  over a wireless or over-the-air link  706  in a mobile environment. In an illustrative aspect, a radio access network  708  transmits selectively transmits network content  704  via a one-to-many transmission such as Evolved Multimedia Broadcast Multicast Service (eMBMS). eMBMS is a transmission service that can simultaneously send the same combined media signals (such as video and audio) to multiple recipients in the same geographic region using Universal Mobile Telecommunications System (UMTS) Long Term Evolution (LTE) evolved Base Nodes (eNBs) or base stations. 
     An autonomous network interface  710  at the apparatus  702  receives a content item  712  of the network content  704  from a network server  714 . The autonomous network interface  710  caches the content item  712  in a computer-readable storage medium  716 , which can include a storage disk  718 . Alternatively or in addition, the computer-readable storage medium can include flash memory  720 . 
     A computing platform  722  of the apparatus  702  executes a content consuming component  724  that can use, play, modify, present, or otherwise interact with the content item  712 . For example, the computing platform  722  can access the same computer-readable storage medium  716  as the autonomous network interface  710 . Alternatively, at least one processor  726  of the computing platform  722  can communicate with at least one processor  728  of the autonomous network interface  710  for requesting and obtaining the content item  712  for use, etc. 
     The autonomous network interface  710  can operate to receive the content item  712  during periods in which a portion of the apparatus  702  is deactivated, such as depicted by a power-saving control  730  suspending operation of the computing platform  722 . Thus, an embedded or attached cellular network interface can perform caching when a supported user device sleeps or is turned off. 
     Alternatively or in addition, the autonomous network interface  710  can serve as a scavenger class implementation, utilizing a type or particular resources of radio access network  708  that is not being used by the computing platform  722 . For example, a communication device can have wireless capability when running. The autonomous network interface  710  can acquire another radio access network in order to avoid or mitigate degradation of a higher priority data transmission by the computing platform  722 . 
     The autonomous network interface  710  can address the Quality of Service (QoS) treatment of scavenger traffic. The scavenger class is intended to provide deferential services, or less-than best-effort services, to certain applications. Applications assigned to this class have little or no contribution to the organizational objectives of the enterprise and are typically entertainment oriented in nature. These include peer-to-peer media-sharing applications, gaming applications, and any entertainment video applications. Scavenger traffic can be assigned the lowest configurable queuing service. Assigning scavenger traffic to minimal bandwidth queue forces it to be squelched to virtually nothing during periods of congestion, but allows use of available bandwidth when not being used for business purposes, such as might occur during off-peak hours or when the computing platform  722  is in standby mode. The autonomous network interface  710  can support battery and storage optimization as well as content security. 
     In  FIG. 14 , a methodology  800  is depicted for acquiring content in a mobile environment. Receiving a content item by an autonomous network interface at a device is depicted in block  804 . In an exemplary aspect, the content item is transmitted from a network via a one-to-many transmission, although the content item could also be requested in a one-to-one communication session. Caching the content item by the autonomous network interface in a computer-readable storage medium is depicted in block  806 . Accessing of the content item by a content consuming component at the device is depicted in block  808 . In an exemplary aspect, this access is subsequent to suspending operation of a computing platform that executes the content consuming component while receiving the content item by the autonomous network interface. 
     Referring to  FIG. 15 , in an aspect, an apparatus  900  that acquires and presents content items may reside at least partially within mobile device, such as a wireless communication device. It is to be appreciated that apparatus  900  is represented as including functional blocks, which can be functional blocks that represent functions implemented by a processor, software, or combination thereof (e.g., firmware). Apparatus  900  includes a logical grouping  902  of electrical components that can act in conjunction. For instance, logical grouping  902  can include a module or electrical component  904  for receiving a content item by an autonomous network interface at a device. For an additional instance, logical grouping  902  can include a module or electrical component  906  for caching the content item by the autonomous network interface in a computer-readable storage medium. For another instance, logical grouping  902  can include a module or electrical component  908  for accessing of the content item by a content consuming component at the device. Additionally, apparatus  900  can include a memory  920  that retains instructions for executing functions associated with electrical components  904 - 908 . While shown as being external to memory  920 , it is to be understood that one or more of electrical components  904 - 908  can exist within memory  920 . 
     Those of skill would further appreciate that the various illustrative logical blocks, modules, circuits, and algorithm steps described in connection with the aspects disclosed herein may be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure. 
     As used in this application, the terms “component”, “module”, “system”, and the like are intended to refer to a computer-related entity, either hardware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components may reside within a process or thread of execution and a component may be localized on one computer or distributed between two or more computers. 
     The word “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. 
     Various aspects have been presented in terms of systems that may include a number of components, modules, and the like. It is to be understood and appreciated that the various systems may include additional components, modules, etc. or may not include all of the components, modules, etc. discussed in connection with the figures. A combination of these approaches may also be used. The various aspects disclosed herein can be performed on electrical devices including devices that utilize touch screen display technologies or mouse-and-keyboard type interfaces. Examples of such devices include computers (desktop and mobile), smart phones, personal digital assistants (PDAs), and other electronic devices both wired and wireless. 
     In addition, the various illustrative logical blocks, modules, and circuits described in connection with the aspects disclosed herein may be implemented or performed with a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. 
     Furthermore, the one or more aspects may be implemented as a method, apparatus, or article of manufacture using standard programming or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computer to implement the disclosed aspects. These aspects may be implemented in an “article of manufacture” or alternatively, a “computer program product”, which as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer readable media can include but are not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips . . . ), optical disks (e.g., compact disk (CD), digital versatile disk (DVD) . . . ), smart cards, and flash memory devices (e.g., card, stick). Additionally it should be appreciated that a carrier wave can be employed to carry computer-readable electronic data such as those used in transmitting and receiving electronic mail or in accessing a network such as the Internet or a local area network (LAN). Of course, those skilled in the art will recognize many modifications may be made to this configuration without departing from the scope of the disclosed aspects. 
     The steps of a method or algorithm described in connection with the aspects disclosed herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. An exemplary storage medium is coupled to the processor such the processor can read information from, and write information to, the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an ASIC. The ASIC may reside in a user terminal. In the alternative, the processor and the storage medium may reside as discrete components in a user terminal.
