Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to electronic transmission of media content and, more particularly, to electronic submission of media content for purposes of media purchase or distribution. 
     Description of the Related Art 
     Traditionally, music and movies has been purchased at music stores or video stores, or at music or video departments of larger stores. A consumer will visit the music or video store (or music or video) department and manually browse for music or movies, or similar media content of interest, on albums or compact discs (CDs) or digital video discs (DVDs) or high definition video discs. After the consumer selects the media content of interest, the consumer proceeds to a check-out register to pay for the music or movies being purchased. 
     In recent years, media delivery or distribution over the Internet has become popular. Today, various online media hosting sites permit virtual visitors to purchase and download albums or songs via the Internet (e.g., World Wide Web). However, in order for music or movies to be offered for purchase and download, the electronic content for the music or movies must first be provided to the media hosting sites. 
     Conventionally, a music label or movie studio desirous of selling their productions online produce a tape or disc, and then physically mail the tape or disc to a representative for the media hosting site. More recently, music labels and movie studios have electronically transmitted their productions to the media hosting site, via the Internet. While the Internet may provide many conveniences, such as sending e-mails with file attachments, conventional e-mails with attachments of very large files may be inefficient, may be ineffective, or may fail in transmitting the very large files. 
     Unfortunately, very large files are typically associated with the productions of music labels and movie studios. For example: data may total approximately seven hundred megabytes for a very large file (or collection of files) associated with an eighty minute music album; data may total approximately eight gigabytes for a very large file (or collection of files) associated with a DVD resolution feature length film, or a large collection of music videos or concert performances. Furthermore, a file or collection of files associated with high definition video can be even larger. For example, feature length movies encoded in ProRes 422 (HQ) may be as large as approximately six-hundred gigabytes or more. Accordingly, it should be understood that attendant difficulties may be encountered by music studios or movie studios when they attempt to electronically transmitted such very large files of their productions to the media hosting site, via the Internet. 
     Various different network transport methods may help to overcome such difficulties. Naturally, transport speed and efficiency are always at issue, in choosing suitable transport methods, since the media content files are so large. However, choice of transport methods is greatly complicated by additional competing, cross-cutting concerns such as security, cost, load balancing, reliability, convenience, ease of use, and current availability. 
     For example, while a studio&#39;s network firewalls may provide them with added network security, depending on how such firewalls are configured, the fastest transport methods may or may not be available currently, for use in transporting large (voluminous) digital media content. Eliminating diversity by forcing attempts using only the fastest transport methods, when such transport methods are not currently available, may result in media submission failure. As another example, while eliminating diversity by forcing use of only a “lowest common denominator” transport method may help with availability and ease of use, such transport method may provide only very poor transport speed and performance. 
     From the foregoing, it should be understood that such failure in media content submission or very poor transport speed may cause significant frustration and dissatisfaction on the part of content providers, such as the music or movie studios. Thus, there is a need for improved approaches to manage submission of media to an online media hosting site, where such cross-cutting concerns in transporting voluminous digital media content can be balanced. 
     SUMMARY 
     Broadly speaking, the invention relates to an improved system and method for submission of voluminous media content data. Automated transport mechanism selection may help to ease difficulties in balancing cross-cutting concerns in transporting the voluminous media. The cross-cutting concerns may relate to one or more aspects such as transport speed, security, cost, load balancing, user classification, reliability, convenience, ease of use, and current availability. 
     The invention can be implemented in numerous ways, including as a method, system, device, apparatus (including computer readable medium and graphical user interface). Several embodiments of the invention are discussed below. 
     One embodiment pertains to a method and/or system for transporting media content data over a network to a media submission system. A client media submission program may be provided that supports media submission to the media submission system using a plurality of transport mechanisms. One of the transport mechanisms to be utilized for the media submission may be determined based at least in part on configuration criteria. The media content data may be submitted over the network to the media submission system using the determined one of the transport mechanisms. 
     Another embodiment pertains to a computer readable medium including at least computer program code stored thereon for transporting media content data over a network to a media submission system. The computer program code can, for example, include at least: computer program code for client media submission to the media submission system using a plurality of transport mechanisms; computer program code for determining one of the transport mechanisms to be utilized for the media submission based at least in part on configuration criteria; and computer program code for submitting the media submission over the network to the media submission system using the determined one of the transport mechanisms. 
     Another embodiment pertains to an apparatus for transporting media content data over a Wide Area Network (WAN). The apparatus can, for example, include at least validation test logic and transport control logic. The validation test logic can be configured to determine a validation ranking of a plurality of transport mappings. Upon validating a selected transport mapping from among the plurality of transport mappings of the validation ranking, the validation test logic can be configured to designate the selected transport mapping as a validated transport mapping. The transport control logic can be configured to attempt delivery of the media content data over the WAN according to the validated transport mapping. 
     Other aspects and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of certain embodiments of the invention are discussed below with reference to  FIGS. 1-6 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. 
       FIG. 1  is a block diagram of a media content submission and distribution system  100  according to one embodiment. Media content submission and distribution system  100  may include a digital media service provider such as a media commerce server  102 . Media commerce server  102  coordinates review, purchase, and/or rental of media items through on-line transactions. On-line transactions to purchase media items are also referred to as electronic commerce (e-commerce). In one embodiment, data network  104  includes at least a portion of the Internet. 
     In accordance with one embodiment, an encoding manager  106  encodes media items from metadata and data files containing media content. Encoding manager  106  can encode the media items as they are purchased or prior to purchase by a consumer. 
     In accordance with another embodiment, a medium store  108  stores or has access to media content that has been submitted to media content submission and distribution system  100 . Media store  108  can provide mass storage for media content that is available for purchase via media content submission and distribution system  100 . Thus, media store  108  may store media items that have been generated as well as store media content that have been submitted for distribution by media content and distribution system  100 . 
     Media storage servers  110  represents one or more remote storage servers that couple to the data network  104 . In media content and distribution system  100  shown in  FIG. 1 , the media content (e.g., media content and/or media items that have been encoded from the media content) are stored in media store  108  and retrieved via one or more media storage servers  110 . Once purchased, the media items can be accessed from media store  108  over the data network  106  by way of media storage server  110 . 
     Media content submission and distribution system  100  is accessible to one or more media content providers  112 . A media content provider  112  may be, for example, a movie studio, television network, or record company providing media content that can be distributed via one or more digital media service providers (e.g., via a media distribution system). Each media content provider  112  may submit media content  114 . As an example, media content can be submitted in association with a feature film or television episode. Generally, media content includes metadata and identifies a plurality of data files. 
     Submitted media content is typically very large. As mentioned previously, feature length movies encoded in ProRes 422 (HQ) may be as large as approximately six-hundred gigabytes or more. A Transporter may be embodied as an application or service directed to submission of voluminous media content data. Automation may help to ease difficulties in balancing cross-cutting concerns in transporting the voluminous media. Such cross-cutting concerns may relate to aspects such as transport speed, security, cost, load balancing, user classification, reliability, convenience, ease of use, and current availability. 
     The Transporter may be embodied as a centralized application or service, or as a distributed application or service. For example, as shown in  FIG. 1 , Transporter may operate in a distributed manner as a media content provider&#39;s Transporter client program  116 A, and as respective Transporter server programs  116 B of each of the Media Storage Servers  110 . Initiation of some selected portions of Transporter functionality may be advantageously distributed to the Transporter client program  116 A, while further implementation of the selected portions of Transporter functionality, in response to such initiation, may be advantageously distributed to the Transporter server program  116 B. For example, initiating a Transport Control Protocol (TCP) diagnostic or a User Datagram Protocol (UDP) diagnostic (in part, to determine whether the content provider&#39;s network firewall is configured to provide current availability of TCP or UDP) may be advantageously distributed to the Transporter client program  116 A, while further implementation may comprise echoing replies in response to the Transporter client program&#39;s TCP or UDP diagnostics, which may be advantageously distributed to the Transporter server program  116 B. 
     Similarly, initiation of some other selected portions of Transporter functionality may be advantageously distributed to the Transporter server program  116 B, while further implementation for such other selected portions of Transporter functionality in response to such initiation may be advantageously distributed to the Transporter client program  116 A. For example, initiating load balancing of current server load through control messaging may be advantageously distributed to respective Transporter server programs  116 B of each of the Media Storage Servers  110 . Further implementing load balancing in response to server control messaging, through the Transporter client&#39;s selection of suitable transport mechanisms, may be advantageously distributed to the Transporter server program  116 B. 
     Moreover, initiating overall balancing of cross-cutting concerns in transporting the voluminous media, relating to aspects such as transport speed, security, cost, load balancing, customer classification, reliability, convenience, and ease of use, may be advantageously distributed to the Transporter server program  116 B. The Transporter server program  116 B can provide and/or update configuration criteria to the Transporter client program  116 A (and/or through providing and/or updating a preferred ranking related to the server&#39;s prioritized preferences with respect to different transport mechanisms, and/or through transmitting to the Transporter client program  116 A validation (or invalidation, or undesignation) control messages related to server directives relative to the different transport mechanisms.) 
     Further implementing overall balancing of cross-cutting concerns, through the Transporter client&#39;s selection of suitable transport mechanisms in response to the server&#39;s configuration criteria (and/or to the server&#39;s preferred ranking, and/or to the server&#39;s validation (or invalidation, or undesignation) control messages), may be advantageously distributed to the Transporter client program  116 A. 
       FIG. 2  is a process flow diagram illustrating a method  200  of submitting voluminous media content data to the media submission system, according to one embodiment. The method  200  starts in  FIG. 2 , by providing a client media submission program  202  that supports media submission to the media submission system, using a plurality of transport mechanisms. 
     Priority of a plurality of transport mechanisms may be determined  204 . For example, the plurality of transport mechanisms may be prioritized based on configuration criteria. The configuration criteria may be provided to the client media submission program by the media submission system. 
     One of the transport mechanisms to be utilized for the media submission may be determined  206 . Such determination may be based, at least in part, on the configuration criteria. The determination of the one of the transport mechanisms to be utilized for the media submission may comprise checking its current availability. For example, in  FIG. 2 , decision block  208  indicates checking the transport mechanism&#39;s current availability. Depending upon the current availability of the transport mechanism, the media content data may be submitted  210  over the network to the media submission system, using the determined one of the transport mechanisms. Following the submission  210 , the method  200  can end. 
     However, in case the determined one of the transport mechanisms is not currently available, the method may return to block  206  so that another transport mechanism can be determined. For example, if the determined one of the transport mechanisms employs a User Datagram Protocol (UDP), and if the afore-mentioned UDP diagnostic indicates that UDP is not currently available for connection to a desired one of the media storage servers of the media submission system (and hence the determined one of the transport mechanisms is unavailable), then the method may return to block  206 . Accordingly, the method  200  may determine another one of the transport mechanisms to be utilized for the media submission, and so on, if the checking indicates that the determined one of the transport mechanisms is not currently available. For example, if the other one of the transport mechanisms does not employ UDP, and instead employs the Transport Control Protocol (TCP), and if the afore-mentioned TCP diagnostic indicates that TCP is currently available for connection to the desired media storage server of the media submission system, then decision block  208  finds affirmatively for the availability of the other one of the transport mechanisms. 
     Accordingly, with respect to the determined transport mechanism, such transport mechanism may be adapted for transporting the media submission from the client to one or more of the media storage servers of the media submission system using a determined one of a plurality of network protocols. Hence, the submitting may comprise the client submitting the media submission over the network to the media storage server using the determined one of the plurality of network protocols. 
     Additionally, the submitting may comprise the client submitting the media submission over the network to the media storage server of the media submission system using a determined one a plurality of non-real time Wide Area Network (WAN) protocols. Transport speed and efficiency may be compelling concerns, in choosing suitable transport protocols, since the media content files are so large. Such use of the non-real time WAN protocols may provide particular advantages, and may provide for the particular purpose of satisfying the concern over transport speed and efficiency. 
     Further with respect to the determined transport mechanism, each of the plurality of transport mechanisms may be identified using a respective one of a plurality of transport mappings. For example, for transport mechanisms adapted for transporting the media submission from the client to one or more of the media storage servers of the media submission system using determined ones of the plurality of network protocols, each transport mapping may comprise a respective protocol set identifier and a respective media storage server identifier. The media storage server identifiers may employ, for example, an Internet Protocol (IP) address. While the form of the identifier may vary, each identifier may uniquely identify a respective one of the media storage servers. 
     At least one of the transport mappings may be identified as a validated transport mapping. For example, when availability of the determined transport mechanism is validated, the transport mapping corresponding to the validated transport mechanism may be identified as a validated transport mapping. Determining the one of the transport mechanisms to be utilized for the media submission may be based, at least in part, on the validated transport mapping. 
     Similarly, at least one of the transport mappings may be identified as an invalidated transport mapping. For example, when availability of the determined transport mechanism is invalidated, the transport mapping corresponding to the invalidated transport mechanism may be identified as an invalidated transport mapping. Determining the one of the transport mechanisms to be utilized for the media submission may be based, at least in part, on the validated transport mapping. The one of the transport mechanisms identified by the invalidated transport mapping may be excluded from being utilized for the media submission. 
     In the following discussions of additional figures, it should be understood that “Logic”, includes but is not limited to hardware, firmware, software and/or combinations of each to perform a function(s) or an action(s), and/or to cause a function or action from another logic, method, and/or system. For example, based on a desired application or needs, logic may include a software controlled microprocessor, discrete logic like an application specific integrated circuit (ASIC), a programmed logic device, a memory device containing instructions, or the like. Logic may include one or more gates, combinations of gates, or other circuit components. Logic may also be fully embodied as software. Where multiple logical logics are described, it may be possible to incorporate the multiple logical logics into one physical logic. Similarly, where a single logical logic is described, it may be possible to distribute that single logical logic between multiple physical logics. 
       FIG. 3  is block diagram of the media content submission and distribution system  300  according to one embodiment. The media content submission and distribution system may be accessible to one or more media content providers using a client transporter program  302 A operating on a client. Each media content provider may submit media content data  304  to the media submission system  306 . The client transporter program  302 A may transport the media content data  304  over a Wide Area Network (WAN) to the media submission system  306  for storage in the media store  308 . 
     As a general matter, Wide Area Networks (WANs) may have high latency. However, use of the Wide Area Network (WAN) may still be preferred for a particular purpose of convenience, particularly when the content provider(s) and the transporter program  302 A may be substantially remote from the media submission system. High latency of WANs may make selection of suitable transport mechanisms more difficult or complex. Automated transport mechanism selection may help to ease difficulties in balancing cross-cutting concerns in transporting the voluminous media over high latency WANs. 
     As shown in  FIG. 3 , the client may comprise validation test logic  310 , which may be configured to determine a validation ranking  312  of a plurality of transport mappings. Upon validating a selected transport mapping from among the plurality of transport mappings of the validation ranking  312 , the validation test logic  310  may be configured to designate the selected transport mapping as a validated transport mapping  314 . As shown in  FIG. 3 , the client may further comprise transport control logic  316 , which may be configured to attempt delivery of the media content data  304  over the WAN according to the validated transport mapping  314 . 
     The media submission system  306  may initiate overall balancing of cross-cutting concerns in transporting the media content data  304 , relating to aspects such as transport speed, security, cost, load balancing, customer classification, reliability, convenience, and ease of use. In particular, the media submission system  306  may provide and/or update configuration criteria to the client  302 A. The client  302 A may implement overall balancing of cross-cutting concerns based on the configuration criteria. Namely, the client&#39;s selection of suitable transport mechanisms can be based on the configuration criteria provided by the media submission system  306 . 
     For example, the media submission system  306  may provide and/or update the client with a preferred validation ranking  320  of transport mappings, related to the media submission system&#39;s prioritized preferences with respect to different transport mechanisms. Also, through transport mapping validation control messaging  322 , the media submission system  306  may invalidate  324  and/or validate  326  transport mappings that affect the client&#39;s validation test logic  310 . 
     In particular, the media submission system may initiate load balancing  328  or failover  330  messages (and/or corresponding transport mapping validation/invalidation/undesignation control messages). In response thereto, the client&#39;s validation test logic  310  may be configured to determine the validation ranking  312  of the plurality of transport mappings. 
     Furthermore, in balancing the cross-cutting concerns, various different transport mechanism prioritizations are suited to various different kinds of media content. The larger an amount of data of the media content, the more important the transport speed, at the expense of server load and transport cost. With respect to type of audio-visual media, music files are typically smaller, so transport speed may be less important, relative to importance of transport cost savings. With respect to different media encoding types, some result in more compact files sizes than others. Accordingly, as shown in  FIG. 3 , the client&#39;s validation test logic  310  may be configured to determine the validation ranking  312  of the plurality of transport mappings, based at least in part upon: a measure of an amount of data  332  of the media content data, or an audio-visual media type  334  of the media content data, or a media encoding type  336  of the voluminous media content data. Similarly, the client&#39;s validation test logic  310  may be configured to determine the validation ranking  312  of the plurality of transport mappings, based at least upon other factors, such as quality of service terms or legal terms negotiated by the media content provider. 
       FIG. 4  is a block diagram illustrating a client media submission program that supports media submission to the media content submission and distribution system using a plurality of transport mechanisms. The client transporter program  402 A shown in  FIG. 4  transports the media content data over the Wide Area Network (WAN). The client may comprise validation test logic  410 , which may be configured to determine a validation ranking  412  of a plurality of transport mappings  413 . Upon validating a selected transport mapping from among the plurality of transport mappings of the validation ranking  412 , the validation test logic  410  may be configured to designate the selected transport mapping as a validated transport mapping  414 . Transport control logic  416  may be configured to attempt delivery of the media content data over the WAN according to the validated transport mapping  414 . Upon any invalidation of any member or members of the plurality of transport mappings  413 , the validation test logic may be configured to determine iteratively the validation ranking  412  of the plurality of transport mappings  413 . 
     The validation test logic  410  may be configured to accommodate one or more validation test modules  418 . The validation ranking  412  may be used for prioritizing selection of a transport mapping for validation test. Upon favorable validation test determination by the validation test module  418  of availability of a selected transport mechanism identified by the selected transport mapping, the selected transport mapping may be designated by the validation test logic  412  as the validated transport mapping  414 . Upon any invalidation of any member or members of the plurality of transport mappings due to unfavorable validation test  418  determination, the validation test logic  410  may be configured to determine iteratively the validation ranking  412  of the plurality of transport mappings  413 . 
     Various diagnostics and/or tests may be employed. As an example illustrating both a particular diagnostic and an unfavorable test determination, if the UDP diagnostic  420  indicates that a selected transport mechanism requiring UDP is not currently available for connection to a desired one of the media storage servers of the media submission system, then the validation test logic  410  may invalidate the selected transport mapping identifying the selected transport mechanism. 
     As an example illustrating both another diagnostic and a favorable test determination, if the TCP diagnostic  422  indicates that a selected transport mechanism requiring only TCP (and not UDP) is currently available for connection to a desired one of the media storage servers of the media submission system, then the validation test logic  410  may validate the selected transport mapping identifying the selected transport mechanism, and delivery of the media content data over the WAN according to the validated transport mapping  414  may be attempted. 
     The validation test module  418  of the validation test logic  410  may be configured to determine transport status  424 , indicating a success or a failure of transport of the media content data over the WAN in accordance with the validated transport mapping. The validation test logic  410  may invalidate the validated transport mapping based upon the transport status  424  indicating the failure of transport of the media content data over the WAN in accordance with the validated transport mapping. Upon any invalidation of the validated transport mapping due to the transport status  424  indicating the failure of transport of the media content data over the WAN in accordance with the validated transport mapping, the validation test logic may be configured to determine the validation ranking of the plurality of transport mappings. 
     As discussed, testing may be performed, and validation/invalidation decisions may be made locally. Alternatively, they may be done remotely. The validation test module  418  may further comprise transport mapping validation control messaging  426  for receiving control messages from the content submission system, and/or from one or more storage servers of the content submission system. As discussed previously herein, in response to receiving such transport mapping validation control messages, the validation control logic  410  may invalidate one or more transport mappings; or may validate one or more transport mappings; or may undesignate one or more transport mappings. In particular, a transport mapping already designated as a validated transport mapping may be undesignated as such; and a transport mapping already designated as an invalid transport mapping may be undesignated as such. 
       FIG. 4  further shows a plurality of WAN protocol sets, which are identified by the transported mappings. At least one WAN protocol set comprises at least one multilayer WAN protocol having a stateless transport layer protocol. 
     At least one WAN protocol set  426  comprises a pair of multilayer WAN protocols, wherein a first member of the pair has a stateless transport layer protocol  428  for transporting the media content data, and the other member of the pair has a stateful transport layer  430  for transporting flow rate feedback data, which can be used in controlling flow rate of the media content data of the first member.  FIG. 4  shows a feedback reader  432  for reading the flow rate feedback data, and a rate controller  434  for use in controlling flow rate of the media content data of the first member. 
       FIGS. 5A-5C  are block diagrams of the media content submission and distribution system according to additional embodiments. In  FIGS. 5A-5C  the media storage servers embody many of the functionalities already discussed in detail with respect to the media submission system of  FIG. 3 . Each of the media storage servers is identified by a respective media storage server identifier. In  FIGS. 5A-5C  the clients are generally similar to the client of  FIG. 4 , already discussed in detail previously herein.  FIGS. 5A-5C  particularly illustrate that the client may support media submission to one or more storage servers of the media submission system using a plurality of selectable transport mechanisms. 
     The transport mechanism illustrated in  FIG. 5A  may achieve a high transport speed, and accord a preferred top priority in the validation ranking. As shown, one WAN protocol set comprises a pair of multilayer WAN protocols, wherein a first member of the pair has a UDP transport layer protocol for transporting the media content data, and the other member of the pair has a TCP transport layer for transporting flow rate feedback data, for use in controlling flow rate of the media content data of the first member. 
     A transport mechanism employing the IRSNYC protocol as illustrated in  FIG. 5B  may help in avoiding any unnecessary transporting of portions the media content to the media storage server, by transporting media content difference data, to any extent that differences may exist relative to any media content already on the media storage server. Some similar benefits may flow from using the RSYNC protocol in combination with an SSH shell, instead of the IRSYNC protocol. 
       FIG. 5C  illustrates a transport mechanism employing the HTTPS and TCP multilayer protocol. While transport using HTTPS on top of TCP may be substantially slower than other alternative transport mechanisms employing UDP, HTTPS on top of TCP may be available in cases where UDP based alternatives are unavailable. 
       FIG. 6  is a process flow diagram illustrating a method  600  of submitting media content data to a media submission system according to another embodiment. The method  600  can start with determining a validation ranking  602  of a plurality of transport mappings. The validation ranking may be used for prioritizing selection of a transport mapping for performing validation. At decision block  604 , no transport mappings may be selected if no transport mechanisms are available, and if all transport mappings have been invalidated. In such negative case, status may be updated  614  to the effect that no transport mechanisms are available, and the method  600  can end. 
     At decision block  604 , in an affirmative case, a transport mapping having a top priority in the validation ranking may be selected. Validation may be performed  606  on the selected transport mapping. 
     At decision block  608  the selected transport mechanism identified by the selected transport mapping may not pass validation, for example, if the selected transport mechanism is unavailable. In such negative case, the selected transport mapping may be invalidated  609 , and the validation ranking may again be determined  602 , now taking into account the transport mapping invalidation. 
     At decision block  608 , in an affirmative case the selected transport mechanism identified by the selected transport mapping may pass validation. Upon validating the selected transport mapping, the selected transport mapping may be designated as a validated transport mapping. The delivery of the media content data over the WAN according to the validated transport mapping may then be attempted  610 . 
     At decision block  612 , the attempted delivery over the WAN according to the validated transport mapping may be unsuccessful. In such negative case, the validated transport mapping may be invalidated  609 . At decision block  612 , in an affirmative case the attempted deliver is successful, the status is so updated  614 , and the method  600  can end.
