The present invention relates to a network-based system for distributing and consuming digital media while preserving the rights of the original copyright owners including artists, publishers, labels, and distributors.
Digital music emerged and introduced users to a new way to acquire and consume music. The digital medium gives consumers instant access to music via electronic networks, such as the internet. The emergence of widely adopted standards such as MP3 allows consumers to acquire music anywhere on the internet and play them on their personal computers (PCs) and portable devices.
However, digital music has also created a serious intellectual property protection problem. Beginning with Napster®, the music industry has been unable to control the distribution of music via person-to-person (P2P) sites, download sites, and the like. This illegal sharing of music has resulted in significant loss of sales.
Many Digital Rights Management (DRM) technologies have emerged including Microsoft's Windows Media® DRM and Apple's FairPlay®. These technologies have suffered from a lack of interoperability due to competitive/licensing issues as well as expensive implementation requirements. A successful DRM protection scheme requires implementation by services, device manufacturers and software player developers. Furthermore, once implemented, even the most secure DRM implementations can be broken—once again leaving files unprotected.
Preferred embodiments of the present invention provide a network-based DRM system that manages digital media assets stored in the network. The system provides consumers with access to the digital media from any internet-connected device while enforcing the intended uses by the copyright owners.
For consumers, the present invention provides the benefits of portability/convenience and instant gratification enabled by a network-based system. The system also provides a more future-proof service capable of delivering new media types/formats from the web as technology changes.
For the content owners, a network-based approach protects against rampant piracy. By delivering the product directly from the network, only authorized users and devices can access the media. Access by users and devices is controlled on the web and can be constantly adapted to changing technologies and market pressures.
The foregoing summary, as well as the following detailed description of preferred embodiments of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings embodiments which are presently preferred. However, the invention is not limited to the precise arrangements and instrumentalities shown.
In the drawings:
Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention.
The present invention is described in the context of a preferred embodiment of a web-based software application commercialized on the World Wide Web at lala.com, which is a music trading and purchasing site. This site is described, in part, in U.S. Application Publication No. 2007/0244768 (Nguyen et al.) entitled “Article Trading Process,” which is incorporated by reference herein. Lala.com is a service of la la media, inc., Palo Alto, Calif. However, the scope of the present invention is not limited to this particular implementation of the invention and may be implemented separate from this platform.
The present invention is described in the context of a plurality of distributed computers, all of which are linked together by an electronic network, such as the Internet. The computers may be any type of computing device that allows a user to interact with a web site via a web browser. For example, the computers may be personal computers (PC) that run a Microsoft Windows® operating system. The computers may also be handheld, wireless devices.
The following definitions are provided to promote understanding of the present invention.
digital media content file: This file holds the actual content of the digital media. If the digital media is audio or audio/visual content, then the digital media content file can be any conventional type of audio file format (e.g., mp3, aav, wav) or video file format (e.g., avi, mpg, vob, asf, wmv, mp4, ogm, 3gp, divX, or other formats used on DVDs). In the music environment, an “individual digital media content file” may be particular track (song), playlist, or album, and does not include an entire catalog of music from disparate artists, such as all music owned or licensed by a particular record label. The digital media content file includes the full contents of the work, as opposed to excerpts or snippets. For example, if the work is a song, the file includes the full song, not 30 second samples.
media content device: This device holds and/or plays digital media content files. In one preferred embodiment, the media content device is a portable digital music player, such as an MP3 player (either a separate device or part of a cell phone or other auxiliary portable electronic device), an iPod®. In another embodiment, the media content device is a portable storage device only, such as a flash memory. In another preferred embodiment, the media content device is a computer, such as a PC that has media playing software installed therein. In the embodiments wherein the user is only permitted to stream media, the media content device does not permanently store the digital media content files, but may temporarily store the files in random access memory or the like to facilitate seamless playing.
own: ownership as used herein is defined by the rights conveyed or licensed by the entity that the user acquires rights of use. In most instances, the user acquires access rights from a copyright owner, and thus ownership means ownership of license rights defined by the copyright owner. In instances where the user creates a work, ownership provides more extensive rights provided under the copyright laws for such creators.
album: one or more audio recordings issued together, originally released on 12-inch phonograph records (usually with record covers) and later on cassette audio tape and now usually on compact disc. Albums and compact discs (CDs) or “discs” are used interchangeably throughout the disclosure.
host computer system: a computer or processor that administers the network-based DRM System of
unlimited streaming: The scope of “unlimited” includes having no restrictions on the number of times that a digital media content file can be played for either a fixed period of time or forever, and also includes a finite number of times over a fixed time period that is great enough to be perceived by the user as being effectively unlimited based on even very heavy usage patterns, while providing for protection against user abuse.
In one preferred embodiment, digital media content files are delivered from a host computer system via an electronic network to media content devices associated with a plurality of authorized users. This process operates as follows:
1. A plurality of different levels of access rights are provided to individual digital media content files. Each of the different levels of access rights has an associated payment amount. More specifically, a first level of access rights has a first payment amount which provides unlimited streaming rights to an individual digital media content file from the host computer system to a user's media content device who has paid the first payment amount. One or more other levels of access rights have respective payment amounts greater than the first payment amount which provides less restrictive access rights to the digital media content file than the first level of access rights.
2. The host computer system maintains records of a plurality of authorized users and a level of access rights for any digital media content file that a user has made a payment for.
3. Individual digital media content files are delivered from the host computer system via the electronic network to the media content devices associated with a plurality of authorized users in accordance with the user's level of access rights maintained in the host computer system.
A level of access rights upgrade payment can be made so as to increase the access level from the first level of access rights to the one or more other levels of access rights. For example, one of the other levels of access rights may provide for downloading of the digital media content file from the host computer system to a user's media content device.
The host computer system may include a plurality of sources of digital media content files, including existing third-party sources of such digital media content files.
“Web Songs” (discussed below) provides one example of such unlimited streaming rights.
In another preferred embodiment for delivering digital media content files, the host computer system has a purchasing component and a delivery component and the selected digital media content files are maintained at the host computer system. The purchasing component may include a plurality of sources for purchasing digital media content files. Likewise, the delivery component may include a plurality of sources for delivering digital media content files. This process operates as follows:
1. A digital media file list is maintained for each user at the host computer system that includes digital media content files that the user is permitted to receive.
2. The digital media file list is populated by scanning storage files of the user's computer to identify any digital media content files stored therein, uploading a list of any identified digital media content files to the host computer system, and adding to the list any digital media content files that the user purchases from the purchasing component of the host computer system.
3. A digital catalog user interface display screen is provided that includes the entries in the digital media file list and allows for user selection of entries.
4. The digital media content files are delivered from the delivery component of the host computer system via the electronic network to the media content devices associated with a plurality of authorized users in accordance with the user's selected entries.
In another preferred embodiment of the present invention, the host computer system is populated with digital media content files for subsequent delivery of the digital media content files. This process operates as follows:
1. Storage files of the user's computer are scanned to identify any digital media content files stored therein.
2. A list of any identified digital media content files is uploaded to the host computer system.
3. The list of the identified digital media content files is compared with the digital media content files currently maintained at the host computer system and any digital media content files stored in the user's computer that are not currently maintained at the digital media content file are identified.
4. The host computer system requests from the user's computer any identified digital media content files stored in the user's computer that are not currently maintained at the host computer system.
5. Any such identified digital media content files are automatically uploaded from the user's computer to the host computer system. In this manner the host computer system will be able to subsequently deliver digital media content files via the electronic network to media content devices associated with the user without needing to access any digital media content files stored on the user's computer.
The digital media content files in the host computer system are preferably stored in a predefined number of supported formats. Thus, the format of any identified digital media content files stored in the user's computer that are not currently maintained at the digital media content file is checked and any such digital media content files that are not in one of the predefined number of supported formats may be transcoded into one of the predefined supported formats prior to the automatic uploading.
Another embodiment for delivering digital media content files to media content devices allows for different levels of access rights depending upon the type of media content device that the digital media content file is delivered to. This process operates as follows:
1. A plurality of different levels of access rights is provided to individual digital media content files. Each of the different levels of access rights are dependent upon the type of media content device that the individual digital media content file is delivered to.
2. Records are maintained in the host computer system of the different level of access rights for each of the different types of media content devices.
3. Individual digital media content files are delivered from the host computer system via the electronic network to the media content devices in accordance with the level of access rights maintained in the host computer system.
In other embodiments, gifts can be made of access rights to individual digital media content files. To facilitate the gifting process, the host computer system compares the gift request to the user's digital media file list to determine if the level of access rights that the gift giver has requested is already permitted by the user for the individual digital media content file. The gift request is only accepted if the level of access rights is not already permitted by the user. If the user already has the access rights requested by the gift giver, the host computer system preferably suggests either a different, less restrictive level of access rights if one exists, or suggests a different digital media content file to give as a gift. The suggestion may be generated from an analysis of metadata associated with the contents of the user's current digital media file list.
The gift may be for a digital media content file that the user does not have any access to, such as a “Web Song” or the gift may be an upgrade in the level of access rights to a less restrictive level, such as upgrading the user from unlimited streaming only (“Web Song”) to downloading access rights.
Upon completion of processing the gift request, the individual digital media content file is immediately added to the digital media file list so that the user has immediate access rights to the individual digital media content file without the user needing to take any action to facilitate the access rights associated with the gift. Thus, the user does not need to redeem credits, respond to an email message, or enter any codes, account numbers or passwords to receive the gift. Preferably, the host computer system allows the user to exchange the gift for an account credit for the monetary value of the gifted access rights to apply towards access rights to a different individual digital media content file, or for an immediate exchange for access rights to a different individual digital media content file that has a monetary value similar to the monetary value of the gifted access rights.
One implementation of the present invention is described below.
a. The copyright owner 23 (e.g., label, distributor) chooses to make the digital media available for use.
b. Users may choose to upload content already owned (see Uploader process below).
c. Third parties can make their digital media available so that it is managed by the web-based infrastructure 11 (see 3rd party system or web-based application 14). The “host computer system” referred to herein includes the combination of the web-based infrastructure 11 and any 3rd party system or web-based application 14 that interacts with the web-based infrastructure 11 to extend its capabilities, for both purchasing of digital media and delivering of digital media from and to users.
In a music example, the digital tracks are stored in the CFS 12 within the web-based infrastructure 11. The CFS 12 manages the serving of digital tracks for approved use by other components of the system (e.g., streaming, downloading). By storing the media, the web-based infrastructure 11 can provide an end-to-end solution for accessing the media.
A server in the CMS 12 generates a file path that identifies its location, the source that populated the content, and a common key to the catalog managed by the system. For example, the following structure may be used:
/base/user/short/long/content
where:
base=path base shared by all
user=hash of user identifier
short=short hash of content
long=long hash of content
content=proprietary content identifier matched to the discid table.
Access to the digital media is controlled by the Digital Rights Management (DRM) process. The DRM process 28 is invoked any time that a user interacts with the managed digital media. The purpose of the DRM process is to assign permissible uses for specific digital media (e.g., a song) for a given user.
Permissible Uses granted by the DRM process may include:
The DRM process can utilize a number of inputs to determine the permissible uses for digital media including the following inputs:
The outcome of the DRM process is to provide access to the ‘most valuable’ asset permissible for the user and device requesting the access. The DRM process is capable of computing the permissible uses in real-time, providing real-time control over the assets. For example, in music, the DRM Process will first check for access to digital tracks provided by the copyright owner. If the user does not meet the necessary criteria, it will check for user uploaded content. If this is not available, the system will check for availability and permission to access 30 seconds samples. This process will continue until an acceptable asset is found or it is deemed that no asset can be provided.
If an asset is found, the DRM process will provide an authorized link to the actual digital media assets stored in the system (or 3rd party system). These links may have different expiration/access rules based on the content characteristics.
3. Importing and Maintaining Information about Digital Media Owned by a User
The system 10 provides an infrastructure for capturing and maintaining a list of the digital media owned by a user. This information can be used as an input to determine a user's permissible rights to access digital media managed by the system 10. This information is stored in the User Digital List table (FIG. 20—Table B). This is the table that stores the “digital media file list” referred to herein.
To obtain a User Digital List which is maintained in the Digital Lists Table 18 of
The user account is stored in the User Table (FIG. 19—Table A).
Once created, a User Digital List can be populated via submissions from a number of sources, such as from a user's computer, web-based catalog, or third-party sites using APIs.
A. From a User's Computer 20
The list may be populated by indexing the media already existing in a user's computer using a Scanner Process 22. In one preferred embodiment, the scanner process 22 runs on a user's local machine (computer 20). Its purpose is to index the media resident on a computer 20. The scanner process 22 can be started explicitly or implicitly by the user. In one preferred embodiment, the scanner process 22 operates as follows:
The Uploader Process 26:
The Uploader runs on the user's local machine (computer 20). The purpose of the uploader process 26 is to upload digital media to the web-based infrastructure 11. The uploader process 26 can be started explicitly or implicitly by the user. The Uploader performs the following steps:
In an alternative embodiment for handling digital media in non-compatible formats, the digital media file is uploaded to the web-based infrastructure 11 in its non-compatible format and the transcoding occurs at the web-based infrastructure 11, instead of the user's computer.
B. From a Web-Based Catalog
The User Digital List may also be populated by adding digital media by selecting from content offered within the system 10. Users could browse for content and add (or purchase) media.
The User Digital List may also be populated directly by end users via manual input. For example, users could register unique identifiers of products owned and/or purchased to prove ownership and add to their digital list.
C. From Third-Party Sites Using APIs
The User Digital List may also be populated by third-party websites via a web service any time that a user makes a purchase of media on their site (3rd party system or web-based application 14). For example, a purchase of a CD or a digital album from any online retailer (e.g., Amazon) could also populate the User Digital List.
Submissions of digital media to the User Digital List are received by Identification Service associated with the Identification Server 24. The Identification Service can utilize unique media identifiers (e.g., UPC, Global Release Identifier (GRid)) and/or metadata (e.g., artist, album, song name, digital fingerprints) to match the submissions against the catalog of digital media managed by the web-based infrastructure 11. The catalog is stored in the Disc Info Table (FIG. 21—Table C.)
As an example, the Identification service can use Artist/Album/Song/Fingerprint information to identify a song as follows:
i. Service looks for an exact match using all pieces of information in Disc Info Table. If one match is found, a match is recorded.
ii. If more than one exact match is found, greater weight is given to more popular albums.
iii. If an exact match is not found, additional lookups are made until a match is found or all additional lookup pairs are exhausted. Additional lookups include artist+song name, artist+album name, album+song name.
iv. Possible matches are converted to a fuzzy-string (vowels, accents, spaces removed) and compared to the fuzzy version of the input data.
v. For every album identified, a 64-bit bitfield is initialized in the User Digital List Table to record the individual song match. The bit in the bitfield whose position matches the song's number (minus one) is flipped to the “on” state to indicate that this song has been matched.
Once songs have been imported and matched, they can be displayed and accessed using the digital catalog managed by the web-based infrastructure 11.
The system 10 also allows for the ‘revoking’ of ownership of digital media. For example, if a user is known to have illegally shared a file, the copyright owner may choose to revoke their ownership of the digital media in the system, limiting the rights of such user to the media. By providing this option, the system can discourage users from illegally using and/or sharing digital media.
The system 10 can be utilized to offer a number of innovative product and pricing offerings for consumption of digital media. In one preferred embodiment, the system 10 can be used to offer a product referred to herein as “Web Songs” for music consumers to collect and purchase new music in an affordable and convenient manner.
Web Songs grant a user the right to access a particular track, playlists, or album in an online collection on a permanent basis. Web songs provide users with a number of features available online including (i) unlimited streaming rights, (ii) ability to add to playlists, and (iii.) ability to share or gift to other users. To grant access, the system 10 places a token or receipt in the user's digital list which corresponds to the relevant digital media. At all times, the system 10 can revoke this access, enabling offering with different degrees of permanence based on duration (e.g., lifetime or 1 year) or use (e.g., 1000 plays).
Web Songs have at least the following characteristics:
For example, if a consumer buys a Web Song and later decides to they want the song for use with their portable device; the consumer can pay an extra amount to download a digital file of the song (e.g. MP3).
a. Network-Based Synchronization Service
The content management process is performed by a user directly on the synchronization service website. The service keeps the record of registered user devices and user selection of media content for each device. The service also holds the actual media playback content.
b. Synchronization Port
The location where the device is physically connected to the system is called a “synchronization port.” The port is typically a user or public PC, internet kiosk, or the like. The connection port runs a synchronization controller process. This process recognizes the portable device and updates its media content.
c. Synchronization Process
Since device content metadata is centralized at the remote service database, it can be accessed from any machine from any location (port). The process of synchronization is initiated explicitly by the user or automatically based on a defined schedule. During the synchronization, the controller process reads the content list of the portable device and compares it with the desired content snapshot from the service (server). As a result of this comparison, the controller process creates a list of media that needs to be either added or removed. The controller then initiates content download from the service and copies downloaded media to the portable device. If the service contains media in a format that cannot be directly played on the portable device, the controller process will transcode such content into a supported format. In addition, the controller process handles mechanics of eventual content protection mechanism.
d. Network-Based Synchronization Optimization Methods
Synchronization sessions can move significant amounts of media content from the local machine (PC) to the remote playback device. In theory, the size of the session's content can be as big as the capacity of the remote playback device itself. Moving the entire content from the server could take a significant amount of time. Two cost reduction methods may be employed to reduce overall time needed to synchronize the device and/or to save bandwidth on the server side:
In
Another embodiment for delivering digital media content files to media content devices allows for different levels of access rights depending upon the “type” of media content device that an individual digital media content file is delivered to. For example, a copyright owner of an individual digital media content file may permit unlimited streaming only to a particular type or class of a mobile phone or portable playing device, either for a set fee or even for no fee. In this manner, a manufacturer (e.g., Apple®) or service provider (e.g., cell phone carrier) could promote their products or services with marketing tie-ins to digital media content files but only with the strict access control provided by the service 10.
The present invention may be implemented with any combination of hardware and software. If implemented as a computer-implemented apparatus, the present invention is implemented using means for performing all of the steps and functions described above.
The present invention can be included in an article of manufacture (e.g., one or more computer program products) having, for instance, computer useable media. The media has embodied therein, for instance, computer readable program code means for providing and facilitating the mechanisms of the present invention. The article of manufacture can be included as part of a computer system or sold separately.
It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention.
