Operational system and architectural model for improved manipulation of video and time media data from networked time-based media

Abstract

The present invention provides a novel operational system and electronic architectural model for organizing and improving viewing and editing of time-based video media and for overcoming the detriments required by the previous film and video industry based editing technologies. The present system enables an operator to manipulate the visual and audio perception of underlying video and audio data without changing the same. A series of metadata modules enable real-time operation and editing of video data and control of a play back module as well as an improved sharing, viewing, searching, and showing of underlying video and audio data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(3) Reference will now be made in detail to several embodiments of the invention that are illustrated in the accompanying drawings. Wherever possible, same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity only, directional terms, such as top, bottom, up, down, over, above and below may be used with respect to the drawings. These and similar directional terms should not be construed to limit the scope of the invention in any manner. The words “connect,” “couple,” and similar terms with their inflectional morphemes do not necessarily denote direct and immediate connections, but also include connections through mediate elements or devices.

(4) Before going further, and in order to fully appreciate the major innovation described in this and the related applications, it is necessary to introduce a new enabling concept which is referred to as the Playback Decision List or hereafter “PDL.” The PDL is a portion of metadata contained within a data model or operational system for manipulating related video data and for driving, for example, a flash player to play video data in a particular way without requiring a change in the underlying video data (DEVSA). This new concept of a PDL is best understood by considering its predecessor concepts that originated years ago in film production and are used today by expert film and video directors and editors.

(5) The predecessor concept is an Edit Decision List or EDL. It is best described with reference to the production of motion picture. In such a production many scenes are filmed, often several times each, in a sequence that has no necessary relationship to the story line of the movie. Similarly, background music, special effects and other add-ons are produced and recorded or filmed independently. Each of those film and audio elements is carefully labeled and timed with master lists.

(6) When these master lists are complete, the film's director and editor sit down, often for a period of months, and review each element while gradually writing down and creating and revising an EDL which is a very detailed list, second by second, of which film sequences will be spliced together in what sequence perhaps with audio added to make up the entire film. Additionally, each sequence may have internal edits required such as fade-in/out, zoom-in/out, brighten, raise audio level and so on. The end result is an EDL. Technicians use the EDL to, literally in the case of motion picture to cut and paste together the final product. Some clips are just cut and “left on the cutting room floor.” Expert production of commercial video follows a very similar approach.

(7) The fundamental point of an EDL is that one takes segments of film or video and audio and possibly other elements and links them together to create a new stream of film or video, audio, etc. The combining is done at the film or video level, often physically. The original elements very likely were cut, edited, cropped, faded in/out, or changed in some other manner and may no longer even exist in their original form.

(8) This EDL technique has proven to be extremely effective in producing high quality film and video. It requires a substantial commitment of human effort, typically many staff hours per hour of final media and is immensely costly. It further requires that the media elements to be edited be kept in viewable/hearable form in order to be edited properly. Such an approach is economically impossible when dealing with large quantities of consumer produced video. The PDL concept introduced herein provides a fundamentally different way to obtain a similar end result. The final “quality” of the video will depend on the skill and talent of the editor nonetheless.

(9) The PDL incorporates as metadata associated with the DEVSA all the edit commands, tags, commentary, permissions, etc. introduced by a user via a User Interface (as will be discussed). It is critical to recognize that multiple users may introduced edit commands, tags, commentary, permissions, etc. all related to the same DEVSA without changing the underlying video data. The User Interface and the structure of the PDL allow a single PDL to retrieve data from multiple DEVSA.

(10) The result is that a user can define, for example, what is displayed as a series of clips from multiple original videos strung together into a “new” video without ever changing the original videos nor creating a new DEVSA file. Since multiple users can create PDLs against the same DEVSA files, the same body of original videos can be displayed in many different ways without the need to create new DEVSA files. These “new” videos can be played from a single or from multiple DEVSA files to a variety of end-user devices through the use of software and/or hardware decoders which are commercially available. For performance or economic reasons, copies or transcodings of certain DEVSA files may be created or new DEVSA files may be rendered from an edited segment, to better serve specific end-user devices without changing the design or implementation of the invention in a significant manner.

(11) Since multiple types of playback mechanisms are likely to be needed such as one for PCs, one for cell phones and so on, the programming model will create a “master PDL” from which algorithms can create multiple variations of the PDL suitable for each of the variety of playback mechanisms as needed. The PDL executes as a set of instructions to the video player.

(12) As discussed earlier, in certain cases it is advantageous to download an encoded file in a form suitable to a specific device type rather than stream a display in real time. In the “download” case, the system will create the file using the PDL and the DEVSA, re-encode it in the appropriate format, and then send that encoded file to the end-user device where it is stored until the user chooses to play it. This “download” case is primarily a change in the mode of delivery rather a fundamentally distinct methodology.

(13) One crucial innovation introduced by proposed PDL is that it controls the way the DEVSA is played to any specific user at any specific Multiple PDLs can exist for each DEVSA file and any PDL can control multiple DEVSA files. It is a control list for the DEVSA player (flash player or other video player). All commands (edits, sequences, tags, comments, permissions, etc.) are executed at playback time while the underlying DEVSA does not change. This makes the PDL in stark contrast to an EDL which is a set of instructions to create a new DEVSA out of previously existing elements.

(14) Having completed the overall supporting discussion, reference is made now to FIG. 1, an architectural review of a system model 100 for improving manipulation and operations of video and time-based DEVSA data. It should be understood, that the term “video” is sometimes used below as a term of convenience and should be interpreted to mean DEVSA, or more broadly time-based media.

(15) In viewing the technological architecture of system model 100, those of skill in the art will recognize that an end user 101 may employ a range of known user device types 102 (such as PCs, cell phones, PDAs, iPods, DVRs et al.) or combinations thereof to create and view DEVSA/video data. Diverse user device types can be used for distinct functions within the overall process described herein without constraint so long as the devices have the required functionality. For example, video may be captured on a camcorder, transferred to a PC from which it is uploaded to a Web site and then later viewed on a DVR or DVD player.

(16) Devices 102 include a plurality of user interfaces, operational controls, video management requirements, programming logic, local data storage for diverse DEVSA formats, all represented via capabilities 103.

(17) Capabilities 103 enable a user of a device 102 to perform multiple interaction activities 104 relative to a data network 105. These activities 104 are dependent upon the capacities 103 of devices 102, as well as the type of data network 105 (wireless, dial, DSL, secure, non-secure, etc.).

(18) Activities 104 including upload, display, interact, control, etc. of video, audio and other data via some form of data network 105 suited to the user device in a manner known to those of skill in the art. The user's device 102, depending on the capabilities and interactions with the other components of the overall architecture system 100, will provide 103 portions of the user interface, program logic and local data storage.

(19) Other functions are performed within the system environment represented at 107 which typically will operate on servers at central locations while allowing for certain functionality to be distributed through data network 105 as technology allows and performance and economy suggest without changing the architecture and processes as described herein.

(20) All interactions between system environment 107 and users 101 pass through a user interface layer 108 which provides functionality commonly found on Internet or cell phone host sites such as security, interaction with Web browsers, messaging etc. and analogous functions for other end-user devices.

(21) As discussed, the present system 100 enables user 101 to perform many functions, including uploading video/DEVSA, audio and other info nation from his end-user device 102 via data network 105 into system environment 107 via a first data path 106.

(22) First data path 106 enables an upload of DEVSA/video via program logic upload process loop 110. Upload process loop 110 manages the uploading process which can take a range of forms.

(23) For example, in uploading video/DEVSA from a cell phone, the upload process 110 can be via emailing a file via interactions 104 and data network 105. In a second example, for video captured by a video camera, the video may be transferred from the camera to the user's PC (both user devices 102) and then uploaded from the PC to system environment 107 web site via the Internet in real time or as a background process or as a file transfer. Physical transmission of media is also possible.

(24) During system operation, after a successful upload via uploading process loop 110, each video is associated with a particular user 101 and assigned a unique user and upload and video identifier, and passed via pathway 110A to an encode video process system 111 where it is encoded into one or more standard forms as determined by the system administrators or in response to a user request. The encoded video/DEVSA then passes via conduit 111A to storage in the DEVSA storage files 112. At this time, the uploaded, encoded and stored DEVSA data can be manipulated for additional and different display (as will be discussed), without underlying change. As will be more fully discussed below, the present data system 100 may display DEVSA in multiple ways employing a unique player decision list (PDL) for tracking edit commands as metadata without having to re-save, and re-revise, and otherwise modify the initially saved DEVSA.

(25) Additionally, and as can be viewed from FIG. 1, during the upload (105-106-110), encodation (110A-111), and storage (111A-112) processes stages of system 100; a variety of “metadata” is created about the DEVSA including user ID, video ID, timing information, encoding information including the number and types of encodings, access information, and many other types of metadata, all of which passes via communication paths 114 and 112A to the metadata/PDL storage facility (ies) 113. There may be more than one metadata/PDL storage facility. As will be later discussed, the PDL drives the software controller for the video player on the user device via display control 116/play control 119 (as will be discussed).

(26) Such metadata will be used repeatedly and in a variety of combinations with other information to manage and display the DEVSA combined with the metadata and other information to meet a range of user requirements. The present system also envisions a controlled capacity to re-encode a revised DEVSA video data set without departing from the scope and spirit of the present invention.

(27) It is expected that many users and others including system administrators will upload (over time) many DEVSA to system environment 107 so that a large library of DEVSA (stored in storage 112) and associated metadata (stored in storage 113) will be created by the process described above.

(28) Following the same data path 106 users can employ a variety of functions generally noted by interaction with video module 115. Several types of functionalities 115A are identified as examples within interact with video module 115; including editing, virtual browsing, commenting, social browsing, etc. Some of these functions are described in related applications. These functions include the user-controlled design and production of permanent DEVSA media such as DVDs and associated printing and billing actions 117 via a direct data pathway 117A, as noted. It should be noted that there is a direct data path between the DEVSA files 112 and the functions in 117 (not shown in the Figure for reasons of readability.)

(29) Many of the other functions 115A are targeted at online and interactive display of video and other information via data networks. The functions 115 interact with users via communication path 106; and it should be recognized that functions 115A use, create, and store metadata 113 via path 121.

(30) User displays are generated by the functions 115/115A via path 122 to a display control 116, which merges additional metadata via path 121A, thumbnails (still images derived from videos) from 112 via paths 120.

(31) Thumbnail images are created during encoding process 111 and optionally as a real time process acting on the DEVSA without modifying the DEVSA triggered by one of the functions 115/115A (play, edit, comment, etc.).

(32) Logically the thumbnails are part of the DEVSA, not part of the metadata, but they may be alternatively and adaptively stored as part of metadata in 113. An output of display control 116 passes via pathway 118 to play control 119 that merges the actual DEVSA from storage 112 via pathway 119A and sends the information to the data network 105 via pathway 109.

(33) Since various end-user devices 102 have distinct requirements, multiple play control modules may easily be implemented in parallel to serve distinct device types. It is also envisioned, that distinct play control modules 119 may merge distinct DEVSA files of the same original video and audio with different encoding via 119A depending on the type of device being supported.

(34) It is important to note that interactive functions 115/115A do not link directly to the DEVSA files stored at 112, only to the metadata/PDL files stored at 113. The display control function 116 links to the DEVSA files 112 only to retrieve still images. A major purpose of this architecture within system 100, is that the DEVSA, once encoded, is preferably not manipulated or changed—thereby avoiding the earlier noted concerns with repeated decoding, modifying, re-encoding and re-saving. All interactive capabilities are applied at the time of play control 119 as a read-only process on the DEVSA and transmitted back to user 110 via pathway 109.

(35) Those of skill in the art will recognize that when a user creates a permanent media version 117, playback decision lists PDLs or play back decision preferences, evolve into edit decision lists (EDLs) or instructions that, along with other metadata such as deep tags and synchronized comments, become tables of contents, indices, section titles or other operative instructions on a fixed media version (DVD).

(36) Those of skill in the art should recognize the common understanding that deep tags are metadata which are used to label and identify select portions of a video as desired and perhaps to allow the sequential generation of a video compilation, whereas an EDL or edit decision list may be used to create a new whole media out of a plurality of previously labeled or tagged pieces/snippets.

(37) It should also be understood, that PDLs and EDLs are different in concept. EDLs are used to define how to encode/create/produce a new, distinct content, whereas PDLs move all decisions into the player to display a distinct content without changing the raw encoded content.

(38) Referring now to FIG. 2, in a manner similar to that discussed with FIG. 1, here an electronic system, integrated user interface, programming module and data model 200 describes the likely flows of information and control among various components noted therein. Again, as noted earlier, the term “video” is sometimes used below as a term of convenience and should be interpreted by those of skill in the art to mean DEVSA.

(39) Here, an end-user 201 may optionally employ a range of user device types 202 such as PCs, cell phones, iPods, DVRs, et al. or combinations thereof which provide user 201 with the ability to perform multiple activities 204 including upload, display, interact, control, etc. of video, audio and other data via some form of a data network 205 suited to the particular user device 202.

(40) User devices 202, depending on their capabilities and interactions with the other components of the overall architecture for proper functioning, will provide local 203 portions of the user interface, program logic and local data storage, etc., as will also be discussed.

(41) Other functions are performed within the proposed system environment 207 which typically operates on one or more servers at central locations while allowing for certain functionality to be distributed through the data network as technology allows and performance and economy suggest without changing the program or data models and processes as described herein.

(42) As shown, interactions between system environment 207 and users 201 pass through a user interface layer 208 which provides functionality commonly found on Internet or cell phone host sites such as security, interaction with Web browsers, messaging etc. and analogous functions for other end-user devices.

(43) As noted earlier, users 201 may perform many functions; including video, audio and other data uploading DEVSA from user device 202 via data network 205 into system environment 207 via data path 206.

(44) An upload video module 210 provides program logic that manages the upload process which can take a range of foam. For video from a cell phone, the upload process may be via emailing a file via user interface 208 and data network 205. For video captured by a video camera, the video can be transferred from a camera to a user's PC and then uploaded from the PC to system environment 207 via the Internet in real time or as a background process or as a file transfer. Physical transmission of media is also possible.

(45) During operation of system 200, and after successful upload, each video is associated with a particular user 201, assigned a unique identifier, and other identifiers, and passed via path 210A to an encode video process module 211 where it is encoded into one or more standard DEVSA forms as determined by system administrators (not shown) or in response to a particular user's requests. The encoded video data then passes via pathway 211A to storage in DEVSA storage files 212.

(46) Within DEVSA files in storage 212, multiple ways of encoding a particular video data stream are enabled; by way of example only, three distinct ways 212B, labeled D.sub.A, D.sub.B, D.sub.C are represented. There is no significance to the use of three as an example other than to illustrate that there are various forms of DEVSA encoding and to illustrate this diversity system 200 enables adaptation to any particular format desired by a user and/or specified by system administrators.

(47) One or more of the multiple distinct methods of encoding may be chosen for a variety of reasons. Some examples are distinct encoding formats to support distinct kinds of end-user devices (e.g., cell phones vs. PCs), encoding to enhance performance for higher and lower speed data transmission, encoding to support larger or smaller display devices. Other rationales known for differing encodation forms are possible, and again would not affect the processes or system and model 200 described herein. A critical point is that the three DEVSA files 212B labeled D.sub.A, D.sub.B, D.sub.C are encodings of the same video and synchronized audio using differing encodation structures. As a result, it is possible to store multiple forms of the same DEVSA file in differing formats each with a single encodation process via encodation video 211.

(48) Consequent to the upload, encode, store processes a plurality of metadata 213A is created about that particular DEVSA data stream being uploaded and encoded; including user ID, video ID, timing information, encoding information, including the number and types of encodings, access information etc. which passes by paths 214 and 212A respectively to the metadata/PDL (playback decision list) storage facilities 213. Such metadata will be used repeatedly and in a variety of combinations with other information to manage and display the DEVSA combined with the metadata and other information to meet a range of user requirements.

(49) Thus, as with the earlier embodiment shown in FIG. 1, those of skill in the art will recognize that the present invention enables a single encodation (or more if desired) but many metadata details about how the encoded DEVSA media is to be displayed, managed, parsed and otherwise processed.

(50) It is expected that many users and others including system administrators (not shown) will upload many videos to system environment 207 so that a large library of DEVSA and associated metadata will be created by the process described above.

(51) Following the same data path 206, users 201 may employ a variety of program logic functions 215 which use, create, store, search, and interact with the metadata in a variety of ways a few of which are listed as examples including share metadata 215A, view metadata 215B, search metadata 215C, show video 215D etc. These data interactions utilize data path 221 to the metadata/PDL databases 213. A major functional portion of the metadata is Playback Decision Lists (PDLs) that are described in detail in other, parallel submissions, each incorporated fully by reference herein. PDLs, along with other metadata, control how the DEVSA is played back to users and may be employed in various settings.

(52) As was shown in FIG. 1 many of the other functions in program logic box 215 are targeted at online and interactive display of video and other information via data networks. As was also shown in FIG. 1, but not indicated here, similar combinations of metadata and DEVSA can be used to create permanent media (DVD's, electronic memory tapes, electronic files stored on any medium of use known to those of skill in the art, etc.).

(53) Thus, those of skill in the art will recognize that the present disclosure also enables a business method for operating a user interface 208.

(54) It is the wide variety of metadata, including PDLs, created and then stored which controls the playback of video, not a manipulation of the underlying and encoded DEVSA data.

(55) In general the metadata will not be dependent on the type of end-user device utilized for video upload or display although such dependence is not excluded from the present disclosure.

(56) The metadata does not need to incorporate knowledge of the encoded DEVSA data other than its identifiers, its length in clock time, its particular encodings, knowledge of who is allowed to see it, edit it, comment on it, etc. No knowledge of the actual images or sounds contained within the DEVSA is required to be included in the metadata for these processes to work. While this point is of particular novelty, this enabling system 200 is more fully illustrative.

(57) Such knowledge of the actual images or sounds contained within the DEVSA while not necessary for the operation of the current system enables enhanced functionalities. Those with skill in the art will recognize that such additional knowledge is readily obtained by means of techniques including voice recognition, image and face recognition as well as similar technologies. The new results of those technologies can provide additional knowledge that can then be integrated with the range of metadata discussed previously to provide enhanced information to users within the context of the present invention. The fact that this new form of information was derived from the contents of the encoded time-based media does not imply that the varied edit, playback and other media manipulation techniques discussed previously required any decoding and re-encoding of the DEVSA. Such knowledge of the internal contents of the encoded time-based media can be obtained by decoding with no need to re-encode the original video so the basic premises are not compromised.

(58) User displays are generated by functions 215 via path 222 to display control 216 which merges additional metadata via path 221A, thumbnails (still images derived from videos) from DEVSA storage 212 via pathway 220. (Note that the thumbnail images are not part of the metadata but are derived directly from the DEVSA during the encoding process 211 and/or as a real time process acting on the DEVSA without modifying the DEVSA triggered by one of the functions 215 or by some other process.) Logically the thumbnails are part of the DEVSA, not part of the metadata stored at 213, but alternative physical storage arrangements are envisioned herein without departing from the scope and spirit of the present invention.

(59) An output of display control 216 passes via pathways 218 to play controller 219, which merges the actual DEVSA from storage 212 via data path 219A and sends the information to the data network via 209. Since various end-user devices have distinct requirements, multiple play control modules may be implemented in parallel to serve distinct device types and enhance overall response to user requests for services.

(60) Depending on the specific end-user device to receive the DEVSA, the data network it is to traverse and other potential decision factors such as the availability of remote storage, at playback time distinct play control modules will utilize distinct DEVSA such as files D.sub.A, D.sub.B or D.sub.C via 219A.

(61) The metadata transmitted from display control 216 via 218 to the play control 219 includes instructions to play control 219 regarding how it should actually play the stored DEVSA data and which encoding to use.

(62) The following is a sample of a PDL—playback decision list—and a tracking of user decisions in metadata on how to display the DEVSA data. Note that two distinct videos (for example) are included here to be played as if they were one. A simple example of typical instructions might be:

(63) Instruction (Exemplary):

(64) Play video 174569, encoding b, time 23 to 47 seconds after start: Fade in for first 2 seconds—personal decision made for tracking as metadata on PDL. Increase contrast throughout—personal decision made for PDL. Fade out last 2 seconds—personal decision made for PDL.

(65) Play video 174569, encoding b, time 96 to 144 seconds after start Fade in for first 2 seconds—personal decision made for PDL. Increase brightness throughout—personal decision made for PDL. Fade out last 2 seconds—personal decision made for PDL.

(66) Play video 174573 (a different video), encoding b, time 45 to 74 seconds after start Fade in for first 2 seconds—personal decision for PDL. Enhance color AND reduce brightness throughout, personal decision for PDL. Fade out last 2 seconds—personal decision for PDL.

(67) The playback decision list (PDLs) instructions are those selected using the program logic functions 215 by users who are typically, but not always, the originator of the video. Note that the videos may have been played “as one” and then have had applied changes (PDLs in metadata) to the visual video impression and unwanted video pieces eliminated. Nonetheless the encoded DEVSA has not been changed or overwritten, thereby minimizing risk of corruption, the expense of re-encoding has been avoided and a quick review and co-sharing of the same (or multiples of) video among multiple video editors and multiple video viewers has been enabled.

(68) Much other data may be displayed to the user along with the DEVSA including metadata such as the name of the originator, the name of the video, the groups the user belongs to, the various categories the originator and others believe the video might fall into, comments made on the video as a whole or on just parts of the video, deep tags or labels on the video or parts of the video.

(69) It is important to note that the interactive functions 215 for reviewing and using DEVSA data, do not link to the DEVSA files, only to the metadata files, it is the metadata files that back link to the DEVSA data. Thus, display control function 216 links to DEVSA files at 212 only to retrieve still images. A major purpose of this data architecture and data system 200 imagines that the DEVSA, once encoded via encodation module 211, is not manipulated or changed and hence speed and video quality are increased, computing and storage costs are reduced. All interactive capabilities are applied at the time of play control that is a read-only process on the DEVSA.

(70) Those of skill in the art should recognize that in optional modes of the above invention each operative user may share their metadata with others, create new metadata or re-use previously stored metadata for a particular encoded video.

(71) Those of skill in the art should also recognize that the use of the phrase media is employed as both a singular noun and sometimes a plural noun within a sentence construction, depending upon the construction itself. Those of skill in the art will recognize that the use of media as singular/plural is readily understood from the language construction local thereto.

(72) Those of skill in the art will additionally recognize, that while the encoding system discussed herein is adaptively linked with the respective system and electronic interface, it will be recognized that each user electronic device necessarily operates with a respective encoding system to achieve the initial time-based media before transmitting the same. Therefore, an alternative embodiment of the present invention will recognize an adaptation wherein the encoding system may be provided additionally by or only by the user electronic device, without departing from the scope and spirit of the present invention.

(73) In the claims, means- or step-plus-function clauses are intended to cover the structures described or suggested herein as performing the recited function and not only structural equivalents but also equivalent structures. Thus, for example, although a nail, a screw, and a bolt may not be structural equivalents in that a nail relies on friction between a wooden part and a cylindrical surface, a screw's helical surface positively engages the wooden part, and a bolt's head and nut compress opposite sides of a wooden part, in the environment of fastening wooden parts, a nail, a screw, and a bolt may be readily understood by those skilled in the art as equivalent structures.

(74) Having described at least one of the preferred embodiments of the present invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes, modifications, and adaptations may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
