Description

PRIORITY CLAIM

The present application is a Continuation application of U.S. patent application Ser. No. 15/786,121 filed on Oct. 17, 2017; which is a Continuation of U.S. patent application Ser. No. 14/621,080 filed on Feb. 12, 2015; which is a Continuation of U.S. patent application Ser. No. 13/622,881 filed on Sep. 19, 2012, now U.S. Pat. No. 8,984,575. The entire disclosure of these prior applications/patents is considered as being part of the disclosure of the accompanying application and hereby expressly incorporated by reference herein.

FIELD OF THE TECHNOLOGY

The present technology relates generally to media packaging and delivery, and, more specifically, to packaging digital media and related files in accordance with a template for delivery.

BACKGROUND

Content producers, such as producers of movies, television shows, and other media content, often produce media content that is licensed by content customers such as cable television providers, Video-on-Demand services, streaming services, etc. The content producers can provide digital versions of media titles (e.g., movies, television show episodes, etc.) to these customers. These customers commonly request multiple media titles at a time (e.g., lists of several movies, seasons of television shows, etc.) from the content producers. For example, an online video streaming service might wish to obtain 100 media titles (e.g., movies) from a movie studio. The online video streaming service might want 100 specifically-identified media titles (e.g., specific movies), or any 100 of the movie studio's media titles, or a mixture of the two. The movie studio can then collect digital versions of the media titles and provide them to the online video streaming service.
Providing digital versions of the media titles to the customer can create challenges for the content producer. Digital versions of media titles can include multiple media files. For example, a digital version of a movie can include one or more video files, one or more audio files (e.g., dialog tracks, background audio, etc.), subtitle files, and metadata files containing information about the movie (e.g., listings of the cast, credits, runtime, etc.). In addition to the challenges presented by providing a large number of media titles, individual customers can have separate requirements for the formats of the digital versions, the language of the dialog tracks and/or subtitle tracks, how the digital versions are packaged, and how the digital versions are delivered. Past approaches involved manually collecting the files for the digital versions of the requested media titles pursuant to the individual customer's requirements, which is time consuming and inefficient.

SUMMARY OF THE INVENTION

With the content customers' increased demand for digital media content, there is a need for an efficient way to collect, package, and deliver digital versions of media titles in a manner specified by the customer. The present technology can provide efficient media packaging and delivery.

Other aspects and advantages of the present technology will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating the principles of the technology by way of example only.

BRIEF DESCRIPTION OF THE DRAWINGS

The foregoing and other objects, features, and advantages of the present technology, as well as the technology itself, will be more fully understood from the following description of various embodiments, when read together with the accompanying drawings, in which:

FIG. 1 depicts an exemplary system for packaging media files;

FIG. 2 is a flow chart illustrating an exemplary computer implemented method of packaging media files;

FIG. 3 illustrates a portion of a packaging template 300 written in XML; and

FIG. 4A-FIG. 4D are a flow chart illustrating an exemplary computer-implemented method of packaging media files.

DETAILED DESCRIPTION

In some embodiments, the technology provides computer-implemented methods and systems that can collect, package, and/or deliver digital media content based on a customer's specified requirements. The technology can allow a content producer to programmatically collect, assemble, package, and deliver a package of media files and metadata associated with the desired media titles to a customer based on the customer's list of desired media titles and a template indicating how the media are to be assembled, packaged, and delivered.
As an example, a media title can be a specific movie. The movie can have one or more media files or media files associated with it. For example, a digital version of a movie can include one or more video files, one or more audio files (e.g., dialog tracks, background audio, etc.), subtitle files, pictures, promotional materials, stills, and metadata files containing information about the movie (e.g., listings of the cast, credits, runtime, etc.). For example, the video portion of the movie can be stored in one media file in 1080p resolution and in a different media file in 720p resolution. As another example, an English dialog track for the movie can be stored in one media file and a French dialog track for the movie can be stored in a different media file.
The technology can facilitate packaging and delivering media files associated with media titles. As an example of the technology, a user can provide to a media packaging server a list identifying media titles or assets (e.g., a list of movies) desired by a customer. The user can also provide to the media packaging server a template identifying various requirements of the customer. For example, the template can specify that the customer wants digital versions of the media titles in MPEG 4 format and 1080p resolution, with an English dialogue track and Spanish and French subtitles. The template can also specify that the customer wants the digital versions of the media titles encrypted and uploaded to the customer's file server. With this information, the media packaging server can collect one or more media files associated with each media title or asset that conforms with the client's requirements (e.g., one or more files with the video portion of the movie in the proper format and resolution, one or more files with the audio portion of the movie in the proper language, and one or more files with the subtitles in the proper languages). The media server can package the files for all of the media titles, encrypt them, and upload the package to the client's file server.
Turning to the illustrated embodiments, FIG. 1 depicts an exemplary system 100 for packaging media files. System 100 includes client 110, media packaging server 120, media repository 130, and recipient 140. Client 110, media packaging server 120, media repository 130, and recipient 140 of system 100 can be connected via network 150. Examples of networks include a bus, a local area network (LAN), a wide area network (WAN), the Internet, wired networks, wireless networks, a packet-based network, and/or a circuit-based network.
In some embodiments, network 150 can include one or more sub-networks (not shown). For example, client 110 can be connected to a private network along with media packaging server 120 and media repository 130. Media packaging server 120 can be connected to a public network along with recipient 140. In such an embodiment, media packaging server 120 can provide the packaged media to recipient 140 without recipient 140 being on the same network as client 110 and media repository 130. It should be appreciated that other network topologies can be used in accordance with the technology disclosed herein.
Client 110, media packaging server 120, media repository 130, and client 140 can each be any computing device, including, for example, a server, personal computer, smart phone, PDA, or tablet. While the illustrated embodiment depicts Client 110, media packaging server 120, media repository 130, and client 140 as separate computing devices, in some embodiments two or more of client 110, media packaging server 120, and media repository 130 can be modules executing on the same computing device.
In some embodiments, media packaging server 120 can package and deliver media files in accordance with the methods described herein. For example, Media packaging server 120 can retrieve medial files from media repository 130, package the media files, and deliver the media files to recipient 140.
Media repository 130 can store and access media files associated with media titles. As described above, media files can be digital files or computer files representing portions of media titles. In some embodiments, each media title (e.g., specific movie, tv episode, etc.) is assigned a media asset ID. Media files for a particular title can be associated with the media asset ID for that media title. The various media files (e.g., high resolution video file, low resolution video file, English dialog track, etc.) for a particular title can be located based on the title's media asset ID. Beneficially, specific files for a media title can be requested from media repository 130 based on a media asset ID.
A media asset ID can be an alphanumeric string. In some embodiments, the characters of a media asset ID relate to the media content of the associated media title, such as including indicia of the show, season, and episode. A media asset ID can uniquely identify a media title within system 100. For example, a particular movie is associated with a media asset ID, along with the various media files containing portions of that movie.
FIG. 2 is a flow chart 200 illustrating an exemplary computer implemented method of packaging media files. In some embodiments, system 100 of FIG. 1 can be used to implement the method illustrated in flow chart 200.
At step 210, a list of one or more media asset IDs is received. For example, media packaging server 120 can receive a list of one or more media asset IDs from client 110 via network 150. In other embodiments, media packaging server 120 can receive the list of one or more media asset IDs from a local disk drive, network storage, or a database. In the exemplary embodiment, the list of media asset IDs can indicate media titles for which media files should be collected. As discussed above, each media title (e.g., specific movie, tv episode, etc.) can be assigned a media asset ID and the media files for each title can be associated with the media asset ID for that media title. The list of one or more media asset IDs can be in any format readable by media packaging server 120. For example, the list of one or more media asset IDs can be in XML, plain text, or binary.
At step 220, a packaging template is received. In some embodiments, media packaging server 120 can receive a packaging template from client 110 via network 150. In some embodiments, media packaging server 120 can receive the packaging template from a local disk drive, network storage, or a database.
A packaging template can specify one or more aspects of how media files should be packaged for a customer. For example, a packaging template can specify the video format in which media files should be delivered, such as MPEG 2 or MPEG 4. A packaging template can specify the resolution for the video media files, such as 720p or 1080p. A packaging template can specify the dialogue track language or languages that should be delivered, such as English, French, and/or Spanish. A packaging template can specify the subtitle language or languages that should be delivered, such as English, French, and/or Spanish. A packaging template can specify whether the packaged files should be compressed, encrypted, and/or packaged as a TAR file. A packaging template can specify how the packaged files should be delivered, such as on a disk or uploaded to a file server.
The packaging template can be in any format readable by media packaging server 120. For example, the packaging template can be in XML, plain text, or binary. FIG. 3 illustrates a portion of a packaging template 300 written in XML. In the illustrated example, packaging template 300 specifies the video format in which media files should be delivered is MPEG 2 (line 310). Packaging template 300 specifies the resolution for the video media files is 720p (line 315). Packaging template 300 specifies the dialogue track language that should be delivered is English (line 320). Packaging template 300 specifies the subtitle languages that should be delivered include French and Spanish (lines 325 and 330). Packaging template 300 specifies the packaged files should be packaged as a TAR file (line 335). Packaging template 300 specifies the packaged files should be delivered to a server (line 340). The sever information can include the server's IP address, protocol, and authentication information.
Returning to FIG. 2 , at step 230, media files are retrieved based on a media asset ID in the list of the one or more media asset IDs and the packaging template. For example, media packaging server 120 can retrieve media files from media repository 130 based on the media asset ID and the packaging template. Media packaging server 120 can request from media repository 130 the media files associated with the media asset that satisfy the requirements specified in the template (e.g., media file format, resolution, language, etc.). As an example, the media asset ID can correspond to a specific movie and the template can specify that video media files should be in MPEG 4 format and 1080P resolution; the dialogue track should be in English; and French subtitles should be included. Media packaging server 120 can request from media repository 130 the media files for the specific movie (using its corresponding media asset ID) that are in the MPEG 4 format and encoded in 1080P; the media files for the English dialog track; and the media file for the French subtitles.
At step 240, metadata associated with the media asset ID are retrieved based on the packaging template. For example, media packaging server 120 can retrieve metadata associated with the media asset ID from media repository 130 based on the packaging template. The template can specify metadata that should be included with the packaged media files. For example, the template can specify that each media asset's run time, producer, cast, production studio, release date, etc. should be packaged with the media files.
At step 250, the one or more media files and the metadata are packaged into a delivery package in a packaging format indicated by the packaging template. For example, media packaging server 120 can package the one or more media files and the metadata into a delivery package in a packaging format indicated by the packaging template. In some embodiments, the template can specify the packaged media files should be encrypted and put in a TAR file. Media packaging server 120 can package the media files retrieved in step 230 and the metadata retrieved in step 240 into an encrypted TAR file.
In some embodiments, the delivery package can be delivered to a location specified in the template. In some embodiments, the packaging template can specify the delivery package should be sent to a server (e.g., recipient 140). Media packaging server 120 can send the delivery package to recipient 140, which can be, for example, an FTP server. In some embodiments, media packaging server 120 can store the delivery package to a storage medium, such as a hard drive or optical medium.
FIG. 4A-FIG. 4D are a flow chart 400 illustrating an exemplary computer-implemented method of packaging media files. In some embodiments, the method illustrated in FIG. 4A-FIG. 4D can be performed by media packaging server 120 of FIG. 1 .
At step 402, a package and delivery request is received (e.g., a list of one or more media asset IDs). At step 404, a customer (e.g., a cable provider, video-on-demand provider, etc.) is selected. In some embodiments, the customer can be selected based on the package and delivery request (e.g., the package and delivery request can include an identification of the customer). In some embodiments, the customer can be selected based on human input through a graphical user interface.
At step 406, it is determined whether a record for the customer is found. If a record for the customer is found, the method proceeds to step 408. If a record for the customer is not found, a record for the customer is created at step 410. In some embodiments, the customer record can be created based on the package and delivery request (e.g., the package and delivery request can include customer information). In some embodiments, the customer record can be created based on human input through a graphical user interface.
At step 408, a packaging template is received. In some embodiments, the packaging template can be received from a local disk drive, network storage, or a database. In some embodiments, the packaging template can be received based on human input or selection through a graphical user interface.
At step 412, media files are retrieved for each media asset ID in the list of media asset IDs in the packaging and delivery request according to the rules specified in the packaging template. At step 414, it is determined if a single media file is found for each component specified in the template (e.g., video, English dialogue track, etc.) of each media title. If a single media file is found for each component, the method proceeds to step 416. If a single media file is not found for each component, the number of media files found is determined at step 418.
If multiple media files for a component are found, the correct media file is selected at step 420. In some embodiments, the correct media asset can be selected based on human input through a graphical user interface. After the correct medial file is selected, the method proceeds to step 416.
If no media files are found for a component, the method proceeds to step 422. At step 422, a media file conforming to the template is generated. For example, if the template specifies that video media files should be in low resolution, a low resolution video media file can be generated from a high resolution video media file associated with the same media asset ID. After the correct media file is generated, the method proceeds to step 416.
At step 416, metadata is retrieved. At step 424, it is determined whether all of the metadata is available. If all of the metadata is available, the method proceeds to step 426. If all of the metadata is not available, the method proceeds to step 428. At step 428, additional metadata is received. In some embodiments, the additional metadata can be received from an external source, such as a website or database containing metadata. In some embodiments, the additional metadata can be received as a result of human input through a graphical user interface.
At step 426, metadata files are generated for the media titles (e.g., for each media asset ID). The metadata files can be generated in a format specified by the packaging template. In some embodiments, the sequence of fields (e.g., title, release, runtime) can be specified. In some embodiments, the packaging template can specify whether the metadata is in XML and/or the XML, schema.
At step 430, a manifest file is generated. The manifest can provide a list of all the files being packaged (e.g., media files, metadata files, etc.).
At step 431, a delivery package is assembled. In some embodiments, the delivery package includes the collected media files, metadata files, and manifest file.
At step 432, it is determined whether the delivery package (e.g., media files, metadata files, and manifest file) should be packaged into a container file. For example, the packaging template can specify the delivery package should be placed in a TAR file. If the delivery package should not be placed into a container file, the method proceeds to step 434. If the delivery package should be placed into a container file, the delivery package is placed into a container file, as specified in the packaging template, at step 436.
At step 434, it is determined whether encryption is required. If encryption is not required by the packaging template, the method proceeds to step 436. If encryption is required, the delivery package is encrypted at step 438.
At step 436, the delivery package is delivered. The delivery package is delivered as specified in the template. In some embodiments, the delivery package can be delivered to a server specified in the template. For example, the delivery package can be delivered to a location specified in the template (e.g., uploaded to an file server specified in the template, published in a shared directory, etc.). In some embodiments, the delivery package can be sent to a storage medium, such as a hard drive or optical medium.
The above-described techniques can be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them. The implementation can be as a computer program product, i.e., a computer program tangibly embodied in an information carrier, e.g., in a machine-readable storage device, for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers. A computer program can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.
Method steps can be performed by one or more programmable processors executing a computer program to perform functions of the invention by operating on input data and generating output. Method steps can also be performed by, and apparatus can be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Modules can refer to portions of the computer program and/or the processor/special circuitry that implements that functionality.
Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor receives instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer also includes, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. Data transmission and instructions can also occur over a communications network. Information carriers suitable for embodying computer program instructions and data include all forms of non-volatile memory, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in special purpose logic circuitry.
To provide for interaction with a user, the above described techniques can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer (e.g., interact with a user interface element). Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input.
The above described techniques can be implemented in a distributed computing system that includes a back-end component, e.g., as a data server, and/or a middleware component, e.g., an application server, and/or a front-end component, e.g., a client computer having a graphical user interface and/or a Web browser through which a user can interact with an example implementation, or any combination of such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), e.g., the Internet, and include both wired and wireless networks.
The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
The technology has been described in terms of particular embodiments. The embodiments described herein are examples for illustration only and not to limit the technology in any way. The steps of the technology can be performed in a different order and still achieve desirable results. Other embodiments are within the scope of the following claims.
