Description:
Embodiments of the invention relate generally to managing content, and more particularly, to methods, systems, and storage mediums for managing content storage and selection services over a network. 
   Television programming customers are currently presented with a fixed interface into their provider&#39;s available on-screen programming listings from which they make choices on programs to view. Many customers utilize personal recording devices in order to build libraries of preferred programs for recurrent or subsequent viewing. These personal recording devices offer fixed amounts of storage, thereby limiting the amount of programming that may be stored by the customer. In order to add to the library, one or more programs need to be removed or deleted from storage, or alternatively, the storage system needs to be upgraded to accommodate additional content. If the customer does not wish to upgrade, he/she may need to regularly monitor the current storage availability, particularly in light of the storage requirements of any selected programming content to be stored. This can be time consuming and burdensome for the customer. Similar disadvantages exist with other content storage devices such as computers, digital music devices, digital cameras, and personal video recorders, to name a few. 
   What is needed, therefore, is a way for customers to create and maintain libraries of content that are easy and convenient to access and manage without requiring upgrades to existing storage systems or the acquisition of additional storage systems.

   DETAILED DESCRIPTION OF THE INVENTION 
   According to exemplary embodiments, the content storage and selection system provides content storage system monitoring, management, and off-site storage services. The content storage and selection system also facilitates the creation and management of content libraries, browsing and acquisition of content from a third-party content library or other content sources, and provides security features. The storage may apply to any type of content such as documents, text files, email, images, video, sound, music, programming, and multi-media. 
   Referring now to  FIG. 1 , a block diagram of an exemplary system for implementing the content storage and selection system is generally shown. The exemplary system of  FIG. 1  includes a host system  114  in communication with content devices  102 - 112  via a network  120 . Host system  114  refers to the entity implementing the content storage and selection services described herein. Users of content devices  102 - 112  may communicate with host system  114  utilizing one or a combination of communications technologies including, e.g., satellite or cellular technology, circuit-switched networking, and packet-switched networking, among others. The telecommunications infrastructure utilized for enabling communications for content devices  102 - 112  are well known and will be readily understood by those skilled in the art. 
   The term “user” as described herein, refers to one or a combination of: a consumer of content (e.g., an individual purchases a song via the Internet and downloads the song to a personal computer; an individual purchases a compact disk (CD) from a ‘brick and mortar’ establishment; etc.); a subscriber of content (e.g., an individual receiving cable/satellite television programming, Internet services, or other content pursuant to a subscription agreement); or a user may be the owner or originator of the content (e.g., pictures taken on a camera or cellular telephone, a composition, story, personal home video, etc.). The term “subscriber” also encompasses other users that do not actually subscribe to a content service but have access to it, such as members in the same household as the subscriber. 
   In accordance with exemplary embodiments, devices  102 - 112  as shown in  FIG. 1  include a computer  102 , a digital music device  104 , an Internet-enabled wireless telephone  106 , a television  108  in communication with a recording device  112 , and a personal digital assistant (PDA)  110 . Television  108  may also include a set top box (not shown) that includes, e.g., a wired or wireless remote control for enabling a customer to access the services provided by the content storage and selection system in conjunction with television set  108 . Alternatively, the functionality of the set top box described above may be incorporated into the recording device  112 . Television  108  may present content pursuant to a subscription agreement with, e.g., a cable television service provider, satellite television service, or may present content originating from a broadcast network or content originating from recording device  112  (e.g., personal home video). 
   According to exemplary embodiments, recording device  112  refers to a system that communicates with television  108  and/or the associated set top box via a wireline or wireless technology, as well as with external systems such as host system  114  via a service provider network as shown in the system of  FIG. 1 . Recording device  112  may receive instructions from a computer user on personal computer  102 , from the set top box and/or television  108 , and/or from host system  114  regarding which programs will be presented on television  108  or recorded by recorder device  112 . Recorder device  112  may comprise memory (e.g., an internal hard drive or DVD drive) whereby digital programming signals are received over the communications network  120  and stored in the memory. Recording device  112  may comprise a commercial product such as TiVo™ produced by TiVo Inc. of Alviso, Calif. In alternate embodiments, recording device  112  may be incorporated in the set top box of television  108  as a single unit. 
   Computer  102  may comprise a desktop, laptop, or other similar general-purpose computing device known in the art. Computer  102  may include memory (e.g., floppy disk drive, hard disk drive) for storing information such as files, documents, images, audio, applications, and multimedia. 
   Digital music device  104  may comprise a portable digital recording and playing device such as an iPod® player by Apple Computer, Inc.® of Cupertino, Calif., or an iAUDIO M3® by Cowon Systems, Inc. of Seoul, Korea. Digital music device  104  may also store digital games, pictures, and personal data such as calendars or organizers, etc. In exemplary embodiments, digital music device  104  plays music in an audio format such as Moving Picture Experts Group Audio Level 3 (MP3), Advanced Streaming Format (ASF), or WAV. A user may download music or other content from the Internet via a computer and store it on the digital music device  104 . The connection between the computer  102  and digital music device  104  may be wireline (e.g., Universal Serial Bus (USB) or may be wireless (e.g., Bluetooth™)). Accordingly, digital music device  104 , as shown in the system of  FIG. 1 , is in communication with computer  102 . Alternatively, a user may copy content from, e.g., a CD, onto computer  102  and, if desired, copy the content from the computer  102  to the digital music device  104 . 
   Wireless telephone  106  may include memory for storing items such as voice messages, text messages, pictures, and personal information, among others. Wireless telephone  106  may communicate via a cell tower and mobile switching center (not shown), which, in turn, may communicate with other networks via a central office (not shown). 
   In exemplary embodiments, PDA  110  comprises a wireless computing device with networking capability such as a web browser and an Internet Service Provider subscription for allowing PDA  110  to communicate digitally with other devices. PDA  110  may include memory for storing documents, files, images, applications, messages, etc. 
   It will be understood that other types of content devices (e.g., digital cameras, personal video recorders, etc.) may also be serviced by the content storage and selection system in order to realize the advantages of the invention. Accordingly, the content devices  102 - 112  as shown in the system of  FIG. 1  are provided for illustrative purposes and are not to be construed as limiting in scope. 
   The content devices  102 - 112  may include a user interface that enables a user to build and browse one or more libraries of content as described further herein. It will be understood that the form of user interface may vary from one content device to another (e.g., voice prompts and selections via key depressions may be used on a telephone, web page user interface screen for a computer user, etc.); however, in exemplary embodiments the functionality of the user interface remains the same across all content devices. The user interface may present a list of all content in the user&#39;s library on a display screen of the content device. The listing of content stored locally on the device and the content stored on the network may be integrated and displayed to the user in such a way that the actual storage location of the content (e.g., content device  102 - 112 , storage device  118 ) is transparent to the user. A user may also share a ‘view’ of his/her library with others on another content device via the user interface. 
   Host system  114  provides content storage and selection system services to its customer/user base. In exemplary embodiments, host system  114  includes a server  116  that executes a content storage and selection application. Server  116  may comprise any suitable high-speed microprocessor capable of handling the volume of activities provided by the features and functions of the content storage and selection application. Server  116  may be accessed over the communications network  120  and may further include a security feature or firewall (not shown) in order to protect the integrity of the data stored within host system  114 . Other security features are described further herein. 
   The content storage and selection application may include business rules for monitoring and removing selected content from a content device, managing the off-site network storage system, establishing and maintaining user accounts, and implementing security features as described herein. The content storage and selection application includes logic that performs functions such as determining what content will be stored locally on a user&#39;s content device and what content should be stored on the network (i.e., storage device  118 ). Various criteria may be utilized by the logic for making these determinations. For example, individual user preferences may be considered. Other criteria may include the total storage capacity of the content device, the available remaining storage in the content device (e.g., when 80% full, relocate content items to network storage), the length of time a particular content item has been stored in the user&#39;s library (e.g., content items stored longer than five days will be relocated to network storage), and where the content to be added to storage exceeds the available remaining storage in the content device. 
   The content storage and selection application may also include logic for inferentially determining how to manage content storage. For example, the logic may determine that frequently accessed content should remain in local storage on the user&#39;s content device in order to allow for quick retrieval. By monitoring users&#39; activities conducted with respect to the users&#39; content libraries, the content storage and selection application may identify relationships and similarities between the various libraries as well as the activities conducted therein. As a result, users may be provided with suggested or preferred content (e.g., users who purchased DVD “A”, also purchased DVD “B”). This logic may be executed at host system  114  or may be shared with content devices  102 - 112 . 
   In exemplary embodiments, host system  114  includes a storage device  118  that is in communication with the server  116  over a network such as a local area network, wide area network, virtual private network, etc. In accordance with exemplary embodiments, storage device  118  refers to an off-site network storage system that stores content on behalf of customers. If the host system  114  described in the system of  FIG. 1  is a content provider such as a cable television enterprise, the programming content stored in storage device  118  may include, e.g., broadcast programming, cable network programming, premium channel programming, pay-per-view programming, on-demand programming, digital music, etc. Alternatively, host system  114  may also store content received from other sources. As described above, host system  114  manages the content libraries of each user. Host system  114  may also manager its own network storage. For example, host system  114  may maintain a single copy of certain content items (e.g., top ten new releases of DVDs) despite the fact that many user libraries may list the content item as being associated with each of the libraries. By doing so, network storage space can be maximized. 
   In exemplary embodiments, storage device  118  also stores user records. User records may include personal information relating to the user (e.g., name, address, email, telephone number, etc.), account information such as billing data, and user content libraries containing listings of content saved in storage by, or on behalf of, a user. 
   Also included in the system of  FIG. 1  is a content owner system  122 . Content owner system  122  refers to an owner of the property rights to a content item or one who possesses related property rights (licensing authority) with respect to the content item. Content owner  122  may be a business enterprise that provides content to its customers via, e.g., a service provider such as host system  114 . For example, content owner  122  may provide premium channel content such as HBO® programming or Showtime® programming under a subscription agreement with its customers. Alternatively, content owner system  122  may refer to an individual, rather than an enterprise, who possesses property rights in a content item (e.g., a copyrighted composition). 
   A content source  124  is also included in the exemplary system of  FIG. 1 . Content source  124  refers to an originating source, or distribution source, of a content item. For example, content source  124  may be a cable or satellite television service provider, an Internet service provider, an online merchant, a physical ‘brick and mortar’ establishment that sells, broadcasts, provides access to, or distributes content. 
   As described above, host system  114  provides the content storage and selection system services to its user/customer base. While host system  114  is described herein as an independent entity, it will be understood that the functionality of the content storage and selection system services may be implemented by, or in conjunction with, other entities such as content owner  122  or content source  124 . Additionally, the host system  114  may also include a server that aggregates content from other content providers and selects and stores the content. 
   An exemplary process for monitoring storage activity and relocating content for a content device will now be described with respect to  FIG. 2 . Host system  114  monitors a customer&#39;s content device via a communications link over network  120  in accordance with the type of content device used by the customer at step  202 . For example, content devices  108  and  112  may be linked to the host system via a Digital Subscriber Line (DSL). Content device  108  displays programming selected by a user either directly by channels transmitting various programming, or by a previously recorded program saved on recording device  112 . These recorded programs may be listed in a customer library for quick searching and access of the content. Utilizing the DSL link to the recording device  112 , host system  114  monitors the remaining available storage space in recording device  112 . 
   As described above, business rules of the content storage and selection application may dictate when and how the customer&#39;s content in storage will be modified. These business rules may be applied in, e.g., a processor at the host system  114 , at the content device, or a combination of both. For example, a content device (e.g., recording device  112 ) may be purged at the request of the customer, only when it reaches its full capacity, when it reaches a pre-determined threshold (e.g., 80%), only when the content to be added to storage exceeds the available remaining storage in the content device, etc. 
   In exemplary embodiments, if the threshold (or other criteria adopted above) has been met at step  204 , the content storage and selection application removes content from the content device (or a reference to the content in the library); otherwise, the monitoring may continue at step  202 . Business rules may be adopted for specifying which content materials will be purged (e.g., the oldest stored content, the largest content files, customer-selected content, least-accessed content, etc.). If the content removed does not already exist in storage device  118  of the host system  114 , the content may be saved to the storage device  118 . If the content removed does exist in storage device  118 , then the content storage and selection application may maintain a single copy of the content that is replicated for each customer who accesses the content and who includes the content in their content library. In this manner, network storage space may be preserved. 
   According to exemplary embodiments, the content storage and selection application associates a link to the removed content within the user library so that the customer may continue to access the content (e.g., via a download over the network  120 ) at step  208 . The demarcation of storage facility sources for content associated with a customer library (e.g., on-site content device storage, off-site network storage) may be imperceptible to the customer. The process returns to step  202  whereby the content storage and selection application may continue monitoring the status of the content device storage. 
   As indicated above, the content storage and selection system may also provide security features and enable content sharing among customers. These features will now be described with respect to  FIG. 3 . According to exemplary embodiments, at step  302  a request to access content stored in storage device  118  is received at the host system  114 . The content storage and selection application performs authentication and validation relating to the request at step  304 . One or more security features may be utilized by the host system  114  for authenticating and validating requests for content. For example, a security feature may be directed to authenticating the individual who is requesting access to content (e.g., via a user identification and password). Another security feature may be directed to validating the user account and content device utilizing, for example, a security token. Additionally, or alternatively, a security feature may be directed to authenticating the content device from which the request was received using, e.g., an identifier associated with the content device that is retrieved over the network. Security may also be implemented by associating a customer content library with a physical transmission medium (e.g., DSL line), which would limit the content access to a fixed physical location (e.g., customer home). 
   In exemplary embodiments, if the authentication/validation performed at step  304  indicates that the request has been initiated by the account owner, the content storage and selection application grants access to the content associated with the account owner (e.g., content library) at step  306 . If the authentication/validation indicates that the request initiated is not by the owner of the account, the content storage and selection application may check to determine whether any permissions exist to view the content at step  308 . For example, the host system  114  may have placed restrictions on the acquisition or sharing of a particular content item listed in the content library such as in the case of premium programming that carry additional subscriber fees. If no restrictions exist at step  308 , the content storage and selection application may grant access to the content at step  310 . This step may include including a listing for the content in the requester&#39;s content library and a link to the storage device  118  for future access to the content. 
   Alternatively, the content owner  122  may have an agreement with the host system  114  whereby content may be shared to non-subscribers of the content owner&#39;s services provided that the content owner receives compensation. At step  312 , it is determined whether the content may be sold to the user. If not, access to the content is denied at step  314 . If there exists an agreement (e.g., implied or express) between the host system  114  and the content owner  122  to sell/share the content, the host system  114  grants access to the content at step  316  for a fee. The agreement may provide the terms and conditions for activities such as which entity (e.g., host system  114 , content owner  122 ) handles the billing and accounting procedures for the transaction. The terms and conditions may also include digital rights management roles and responsibilities of the entities  114  and  122 . At step  318 , the user is billed for the content. In exemplary embodiments, the content storage and selection application tracks this activity and bills the requesting party for the content and content storage and compensates the content owner  122 . 
   According to exemplary embodiments, the content storage and selection system provides content storage system monitoring, management, and off-site storage services. The content storage and selection system also facilitates the creation and management of content libraries, browsing and acquisition of content from a third-party content library, and security features. The storage may apply to any type of content such as documents, text files, email, images, video, sound, and multi-media. A customer (e.g., an individual that subscribes to a content service such as a cable television service, a satellite television service, an Internet service, etc.) may receive content from the content provider in accordance with a service plan (e.g., basic cable service with limited channels, extended cable with selected premium channels, Internet service and messaging, etc.). 
   As described above, embodiments may be in the form of computer-implemented processes and apparatuses for practicing those processes. In exemplary embodiments, the invention is embodied in computer program code executed by one or more network elements. Embodiments include computer program code containing instructions embodied in tangible media, such as floppy diskettes, CD-ROMs, hard drives, or any other computer-readable storage medium, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes an apparatus for practicing the invention. Embodiments include computer program code, for example, whether stored in a storage medium, loaded into and/or executed by a computer, or transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, or via electromagnetic radiation, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes an apparatus for practicing the invention. When implemented on a general-purpose microprocessor, the computer program code segments configure the microprocessor to create specific logic circuits. 
   While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims.
