Definitions

  • This invention relates in general to the use of computer technology to store, edit, and share personal digital video material.
  • DSCs digital still cameras
  • DVCs digital video camcorders
  • webcams computer mounted web cameras
  • DVRs digital video recorders
  • Consumers who generate these video files typically wish to edit their material down to the highlights that they wish to keep, save the resulting edited material on some permanent storage medium, and then share this material with friends and family, or possibly with the public at large.
  • FIG. 1 is a block diagram illustrating a prior art video editing platform including a creation block 199, a consumption block 198, and a media aggregation, storage, manipulation & delivery infrastructure 108.
  • Figure 1 shows with arrows the paths that currently exist for transferring video material from a particular source, including a DSC 100, a DVC 102, a mobile phone 104, and a webcam 106 to a particular destination viewing device including a DVD player 110, a DSTB 112, a DVR 114, a mobile phone 116, a handheld 118, a video iPod 120, or a PC 122.
  • the only destination device that supports material from all input devices is the PC 122. Otherwise, mobile phone 104 can send video material to another mobile phone 116, and a limited number of today's digital camcorders and digital cameras can create video material on DVDs that can then be viewed on the DVD player 110.
  • the video- sharing websites In order to assist visitors to search for videos of interest, the video- sharing websites typically request their members to provide information describing each of their video productions, such as a title and one or more descriptive words that characterize the content of the video.
  • the title and descriptions for each video production are stored as very simple metadata associated with the final video production by the website. They canbe displayed to visitors in simple ways, including sometimes organized by subject matter, and sometimes in the form of a collection of descriptions where the font size varies according to the popularity of the description, the most popular having the largest font.
  • Clicking on a descriptive word brings up a set of thumbnail images of the videos corresponding to the description (often in the form of several successive pages of thumbnail images, one for each referenced video). Clicking on a thumbnail launches the video represented by the thumbnail. . No information or data is provided with regard to the elements that make up the video production.
  • descriptions of the video have additional potential value when applied to online video material. For example, a description could be used to quickly access a specific section within a video production in order to view the specific section, or to reuse the section by inserting it into a new video production. Descriptive words may also be used to automatically aggregate and link together two or more video productions or video sections into a new production.
  • none of these capabilities are offered in any of today's online video-sharing systems.
  • a system and method for uploading, editing and distributing video material in an online environment, whereby users can perform the task of editing their video material online while the same material is being uploaded and stored at a remote Internet-hosted service, regardless of the size of the material.
  • One example of the system comprises an Internet-hosted application service for online storage, editing and sharing of digital video content and a companion client PC-based video upload application.
  • the Internet-hosted application may be based on a group of technologies referred to as asynchronous JavaScript and extensible markup language ("AJAX"), which allows the online editing application to behave as if it resides on the user's local computing device, rather than across the Internet on a remote computing device, such as a server.
  • AJAX asynchronous JavaScript and extensible markup language
  • the online editing application provides users with a "drag-and-drop" interface for creating their video productions.
  • the client PC-based video upload application facilitates the input of lengthy camcorder video material by automatically segmenting, compressing and uploading the material from the user's PC, while allowing users to edit their material during the upload process.
  • the Internet-hosted application service can be used on a dedicated website or its functionality can be served to different websites seeking to provide users with enhanced video editing capabilities.
  • Another aspect enables users to browse or preview video material in an online environment.
  • the example includes variations on the use of thumbnail images, and the use of a virtual joystick to vary the replay speed of the video.
  • users can select the browsing method that they find most effective in previewing video material presented to them.
  • Another aspect stores, edits, and distributes video material in an online environment.
  • One aspect is automated, whereby creators or owners of online video productions may select a production and a destination target, and then publish the production to the destination target with one click.
  • viewers of a video production are allowed to select a destination target and forward the production to any destination with one click.
  • the possible destinations include websites, email recipients, Instant Messaging recipients, mobile phone users, software applications, digital set-top boxes and digital video recorders, as well as any pre-defined combination of these, for example.
  • FIG. 1 Another aspect allows users to share the processes by which video productions have been created, in the form of hyper-templates. Users can designate as shareable the template they used in creating a video production, such that other users may reuse the template in their own productions.
  • One method of invoking a template during the viewing of a video production is by clicking on button or on a watermark within the video that acts as a hyperlink into an online video editor and causes the editor to pre-load the particular template, ready for reuse.
  • styles can be provided which are automated templates. The styles include a template, a question list and a program which automatically applies the template to a user's media.
  • consumers may insert hypervideo links into their video material during the online editing process. Viewers of the video material may optionally follow an inserted hypervideo link by clicking on its visible representation during replay and selecting an alternative non-linear viewing path. [0028] Another aspect allows users to classify video material for future use
  • tags e.g., filtering, advertising, copyright protection, and making recommendations
  • tags by associating tags with specific segments of a video file ("segment tags"), or with specific points in time within a segment (“deep tags”), such that the tags can later be used as search terms to find video productions of particular interest, or to quickly access specific parts of video material for viewing or for reuse in creating a new video production or for advertising or for filtering or for personalization.

For example, if the upload process was uploading all of the compressed upload segments in sequential order and the user dropped an upload segment representing the last sequential portion of the production into the storyline, the upload process may immediately begin to upload the last sequential portion of the production, thereby lowering the priority of the segments that were currently being uploaded prior to the user's editing action.

  • the online video editor 202 provides a method of varying the replay speed of a video production.
  • the replay speed is adjusted by the viewer by means of a virtual joystick, which displays a speed dial ranging from very slow to very fast and allows the user to adjust the speed by using the mouse to move a virtual needle left or right from its central position, which represents normal speed.
  • Using the virtual joystick to replay a video production at high speed creates the effect of time-lapse photography, and provides a way for the viewer to browse the production in a short period of time, and to receive a visual summary of the content that may be more effective than thumbnails, due to its use of motion.
  • Using the virtual joystick to replay a video production at low speed creates the effect of slow motion, and allows users to study sections of video to more accurately determine actions captured in them - actions that may have been missed when viewing at normal speed. For example, by replaying in slow motion a video of a bird flying, a viewer would be able to better study the ways in which the bird moves its wings.
  • variable-speed replay method which also applies to video material played at normal speed, is a process whereby the system partitions the video production into four equal-length segments, and plays the four segments in parallel in a quadrant format. This provides a faster means of browsing a video production in motion form.

  • One automated forwarding method comprises an interface whereby viewers of a video production can select a destination target and forward the production to any destination with one click. Forwarding may be accomplished in a three-step process whereby: (1 ) the user clicks on a "Forward" button displayed with the viewed video, or available through a toolbar.

Users may pre-define destination groups, where each group may consist of any combination of possible destinations. Users may also set up any of the potential destinations or destination groups in their address books, and the system will automatically take care of all issues related to delivery of each video production to the requested destinations.

Where this information is not available, the system may use the default format that most closely matches the device type.
  • the system may use a base decode codec in association with the encode codec required for the selected destination device at steps 1404 and 1406, and may create a copy of the subject material on the server in the destination format, prior to streaming it to the destination at step 1408.
  • the base codec used in steps 1406 and 1408 may be the DivX codec. If the video material is not delivered successfully to a device, the system may provide a feedback mechanism whereby users are solicited to provide details about the device in question.
  • Distribution of video material can be accomplished both directly from an online video-sharing portal website, or indirectly from any website via a toolbar and associated browser plug-in. If a video is posted on another website (e.g., on a blogger's home page or on a Myspace user's home page, for example), the video material is not actually exported, but remains on the video-sharing website, which acts as a proxy server that retrieves and streams the video when requested. In order forward the video, the viewer interacts with the browser plug-in via the toolbar, which communicates with the portal to perform the actual forwarding. Thus the sharing controls established by the owner of the video material are still enforced, and all of the previously described delivery mechanisms still apply.

  • the second method of selecting hyper-templates for reuse involves the use of hyperlinks, and, in particular, hypervideo links.

  • the hypervideo concept extends the use of the hyperlink device to provide a link out of a video production (rather than a text document) to another webpage, typically to another section of video.
  • hyper-template linking is a special case of hypervideo linking, the special case being that the system always transfers control to the online video editor 202, rather than to a destination defined by the video-creator.
  • video productions created by the online video editor 202 are replayed with a TV-like encasement surrounding the video image, with several control buttons located below the image, one such control button being a "Remix" button which, when clicked on, specifically invokes a hyper-template link into the online video editor.
  • video productions created by the online video editor 202 are discretely watermarked with a small logo that appears in the lower left or right corner of the video, for example.
  • the watermark acts as a hyper-template link, in the sense that, if clicked on, it triggers a hyperlink that takes the viewer seamlessly into the online video editor 202, with the hyper-template of the viewed video pre-loaded and ready to be reused in creating a new video production. This is achieved by structuring the hyperlink in

  • websiteaddress and "editor” identify the online editor to be linked to.
  • a hyper-template watermark may be distinguished in several possible ways, such as by having two separate watermarks placed in different areas of the video image, or, in the case of a shared watermark, by a passive appearance for a hyper-template hyperlink (as opposed to flashing, which indicates a hotspot), or by color-coding (e.g., blue indicates a hyper-template link, whereas red indicates a hotspot).
  • a hyper-template hyperlink is initially generated by the online video editor 202 during construction of a video production, and is stored as metadata with the video. The data structures supporting the metadata were described earlier in this section, and shown in Figure 13.
  • the hyperlink metadata remains associated with it. No matter where the video is viewed, on any website, it still retains the hyperlink that will link back to the original online editor if the hypervideo hyperlink is clicked on. This is because the video is never actually exported, but remains on the video-sharing website which acts as a proxy server that retrieves and streams the video when requested.
  • the hyper-template thus not only provides users with a convenient way of sharing and reusing video creation processes, but also benefits the online video sharing website by generating traffic to the website and potentially enlisting new members.
  • the user may be linked into the online video editor 202 and, in one example, is presented with a webpage showing the hyper-template of the selected video in the form of a timeline at the bottom of the screen, with the shareable segments of the related video displayed on the main palette in the center of the screen.
  • the timeline of the hyper-template is displayed vertically at the left or right side of the screen, with an additional vertical window alongside the timeline to allow insertion of text to be used as a commentary relating to the contents of the video timeline. The positioning of the text can be adjusted to appear alongside the particular video sequence that it relates to.

From the selected video, they can reuse any segments that the owner has designated as shareable. Users can also add or remove segments of video.

  • step 1618 may include, for example, the user's set of available segment of deep tags (either within the current production or in other productions created by the user), a set of system-supplied tags to other video material, or a link to any Internet webpage or email message that the user then specifies.
  • the user Having set up the start of the hotspot, if the user has not set up a time- based duration for the hotspot, he or she can then click on a virtual "Continue" button to continue playing the video at step 1614, and then at step 1616 is determined whether the user clicked on the "Pause” button to again stop the video and define the end point-in-time of the hotspot at step 1618.
  • the system automatically applies a user-definable default time for the duration of the hotspot (which, in one example, is initially set to ten seconds).
  • Hypervideo links are also dynamic, in the sense that the creator can alter the targets of links at any time, even after publication. By re- entering the video editor, creators can change productions on the fly, changing the content both in terms of modifying the sequential material and inserting or modifying hypervideo links. This is achieved by deploying the two mechanisms of a proxy server and metadata.
  • video productions created by the system are served dynamically by the system acting as a proxy server to the requesting service.
  • Proxy servers cache frequently referenced material, thus improving performance for groups of users accessing similar content.
  • a video production is posted to another website (e.g., on a blogger's home page or on a Myspace user's home page)
  • the video is may not be actually exported, but can remain on the video-sharing website which retrieves and streams the video when requested.
  • the online video editor creates metadata pertaining to the link, including such information as the tag name and the URL address of the destination.
  • the metadata is stored by the system and its association with the video production is maintained by the system. If the video is posted on another website, the hyperlink metadata remains associated with it. No matter where the video is viewed, on any website, it still retains all hyperlinks that have been defined for it.
  • users may include links to external video material that the system has previously aggregated.
  • the system may have either already created a local copy of aggregated external material, or may have simply provided a link to the material. If the system has not previously stored a copy of the aggregated material locally, but has instead saved a link to the material together with the related commands for retrieving it, the system accesses the material via the API and creates copies of it in Flash and DivX formats, prior to making the material available to be referenced by hypervideo link in the user's production.
  • the system first detects the format and resolution of the subject video material, then selects the appropriate decode software module to handle the detected video format, then decodes the video material from the input format using the selected decode codec, and then encodes it into Flash format using a Flash codec and into DivX format using a Divx codec.
  • the online video editor 202 also handles uploading of video clips directly from a PC, or cell phone, without the need to use the preprocessing application 206.
  • Figure 17 is a diagram illustrating an example process for direct uploading and editing.
  • the online video editor 202 treats each video clip as a separate video segment, and creates a thumbnail image for each segment (based on the first non-blank image detected in the segment's data stream, for example). If the clip includes transitions, the editor detects these and splits the clip into separate segments, creating a new segment following each transition, and builds an accompanying thumbnail image for each created segment. For each segment, the editor prompts the user to supply one or more segment tags. After each segment has been uploaded, the user can review the segment and create additional deep tags defining specific points-in-time within the segment.
  • External content is provided for selection by tag at step 1706.
  • the user is also provided with the ability to add transitions, special effects, as well music or voice overlays at steps 1708 and 1710 before saving the edited work as a new production at step 1712.
  • the drag-and-drop interface provides an extremely simple method of video editing, and is designed to enable the average Internet user to easily edit his or her video material.
  • the process of video editing is thus greatly simplified, by providing a single Internet-hosted source that automatically manages the processes of uploading, storing, organizing, editing, and subsequently sharing video material.
  • the video-editing process is further simplified through the mechanism of hyper-templates, which allow users to reuse video-production processes and methods that they previously created, or that other users have created, or that the system supplies.
  • any new video production will have been constructed from separately defined segments, on completion it will inherently include segment tags for every separate clip included in the production, as well as for every scene transition.
  • the new production will exist as a separate file, but the system also retains separate files for all of segments from which it is constructed.
  • the segments can be rearranged in any manner, or combined in a variety of ways with other tagged segments, to create new productions with tags.
  • a further extension of the tagging concept is embodied in the ability to tag external content, such as photos, music or other external video material, and to include the tagged external content into a video production.
  • a video production can include a mixture of video segments and photos from multiple sources, plus a music overlay, and all segments, photos and music start points will be automatically tagged within the production.
  • the system may also automatically tag all digital content that it has aggregated on behalf of the user. Where a file name or title is supplied with a piece of aggregated material, this may be used as the tag. Where no file name or title is supplied, the system may create a tag in the form of: "Photo mm/dd/yy nnn", “Audio mm/dd/yy nnn”, “Music mm/dd/yy nnn ", "Video mm/dd/yy nnn” or “Animation mm/dd/yy nn", for example, where “mm/dd/yy” is the date when the spidering occurred, and “nnn” is a sequential number representing the sequence in which the piece of material was aggregated by the system on the date specified.
  • the user can change any of the automatically aggregated material tags to a more meaningful tag name.
  • users can create entire video productions by aggregating together a set of tagged segments or sections of video from any source available within the system, including tagged material from external sources. It thus becomes extremely easy for users to create new video productions from existing material from multiple sources, without the need to introduce their own new material. Any such aggregated production will exist as a separate file, but the system also retains separate files for all of aggregated segments from which it is constructed.
  • a further extension of the tagging concept relates to the concept of hypervideo links.
  • a hypervideo link makes its presence known by a visible change in the appearance of an area of the screen, or in the appearance of a watermark which is always present on the video. By clicking on the changed area or watermark, the viewer is given the option of switching out of the current video sequence and following one or more hypervideo links that may lead to another video, or to any tagged segment or section of a video, or to an internet webpage, or into an email message.
  • the online video editor prompts the user to supply one or more tags to be associated with the link.
  • Hypervideo tags then become another form of segment tag, which viewers can subsequently search on, just as they can search on any other form of tag.
  • searching on a hypervideo tag a viewer can gain access to any Internet- connected media source that has been referenced by a video creator.
  • a video creator can also reuse a hypervideo link and include it in a new production, either by reusing it as a non-linear hypervideo link, or by retrieving the linked-to material and including it as one or more inline video segments.
