## Background
TECHNICAL FIELD
The present disclosure generally relates to digital video commenting, and more particularly, to systems and method for recording content within a digital video.
BACKGROUND
Social networking websites for sharing digital videos are common and well known in the art. These websites enable users to upload user-generated or user-recorded digital videos to a server and/or database of the network and share their digital videos with other users on the network to view the digital video. Moreover, digital videos previously uploaded to the network and stored on the network database can be retrieved and locally played back by a plurality of other users on the network. Some such websites may also enable the users to comment on a digital video by allowing them to submit opinions or remarks on a webpage display that contains and/or is linked with the digital video. Comments on a particular digital video may be collectively associated with the digital video and made available for viewing during subsequent playback sessions thereof.
These social networks may enable users to submit and share comments on digital videos, there are still some limitations. At best, the comments submitted by users are associated with the digital video as a whole and are not associated with any particular moment of the digital video. As a result, users wishing to insert a comment typically must specify the particular moment in the digital video that the comment is in reference to. Furthermore, users subsequently viewing the digital video and reading previously submitted comments are often left to guess what moment in the digital video a particular comment is directed to. Additionally, currently existing social networks do not enable users to submit comments in any form other than text data. More particularly, users viewing a digital video and wanting to comment on the digital video are unable to comment on the digital video using audio, video, or any form of data other than simple text.
Baryla, U.S. Pat. No. 5,717,468, discloses a system which enables the recording and displaying of comments associated with a video. However, Baryla is more directed toward video editing and production rather than recording content within socially or publicly shared digital video. Baryla is also solely limited to text comments, and further, requires the video to be paused in order to record a text comment. The system disclosed by Baryla is thus unable to reserve selected video frames to be associated with a comment and dynamically record comments during video playback. Furthermore, Baryla is unable to dynamically display the comments previously recorded without pausing the video.
Walter, et al., U.S. Patent Application No. 2007/0180488, disclose a system for processing video content or tags within a video stream. More specifically, the system disclosed by Walter, et al. is capable of accessing tags carried by a video stream and process a time stamp associated with the tag. Based on the tag and an associated time stamp, the system is able to execute a script that is associated with the tag. However, Walter, et al. is directed more towards set-top boxes or units which process streaming video data to be presented on television screens. More particularly, the tags disclosed by Walter, et al. are limited to performing tag actions associated with parental control features rather than providing means for commenting on shared media.
Prijatel, et al., U.S. Patent Application No. 2002/0199189, disclose a system for inserting supplemental video and audio content into a transmission stream. In particular, Prijatel, et al. discloses analyzing the appropriate time considerations of a transmission, and further, inserting tags into the transmission stream based on the analysis. The tags inserted by Prijatel, et al. are disclosed to include promotional or advertising content. However, the system disclosed by Prijatel, et al. is limited to simple insertion of the tags and is not associated with particular frames of the existing video content. The system disclosed is thus unable to, for instance, concurrently playback the inserted content during playback of the original video transmission.
Accordingly, there is a need to enable users to insert and record user-generated comments into digital videos by associating the comments with not only the digital video but with specific moments of the digital video. There is also a need to enable users to comment on a digital video not only using text data but with any other medium, such as audio and/or video data. The disclosed systems and methods are directed at addressing one or more of the needs set forth above.

DETAILED DESCRIPTION
Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Generally, corresponding reference numbers will be used throughout the drawings to refer to the same or corresponding parts.
Referring now to FIG. 1, an exemplary system 100 for recording user content within a digital video is provided. As shown, the content recording system 100 may generally include at least a storage device 102 which may include a database or any other form of memory suitable for retrievably storing data pertaining to one or more digital videos. The content recording system 100 may further provide a primary network device 104 which may include one or more servers or other suitable computational devices with processors 106 that are configured to manage the storage and retrieval of digital video data to and from the database 102. More specifically, the server 104 of FIG. 1 may be configured to selectively provide one or more users with access to the digital video database 102 over a network 108. The network 108 may be configured as a wide area network (WAN), such as the Internet, a local area network (LAN), or any other shared network that enables wired and/or wireless communications between the server 104 and one or more secondary network devices or clients 110. Each of the client devices 110 of FIG. 1 may include a personal computer, a mobile device, a handheld device, or any other computational device having a user interface 112 which enables user access to the network 108. The user interface 112 may include a combination of input and output interface devices, for example, display screens, touch screens, microphones, speakers, pointer devices, keyboards, and/or any other suitable means for enabling a user to locally input information to and output information from the associated client device 110.
Turning now to FIG. 2, one exemplary video display 114 for displaying a digital video 116 to one or more users at a user interface 112 of a client device 110 is provided. As shown, the display 114 may provide basic navigational controls 118 which enable a user to pause, stop or play the digital video 116, control playback volume, adjust display size, and the like. The display 114 may also provide a scrollbar or timeline 120 which enables a user to view the progress of the digital video 116 as it plays, and/or navigate or skip to a desired segment of the digital video 116. As discussed with respect to the content recording system 100 of FIG. 1, the digital video 116 of FIG. 2 may be retrieved from a digital video database 102 of a shared network 108. For instance, in applications wherein the network 108 is configured as a wide area network, the server 104 may host a social video-sharing website that may be accessed by a plurality of users from different client devices 110. By visiting the website using a web browser, or the like, a user may be able to select a digital video 116 and play the digital video 116 through, for example, the display 114 of FIG. 2, by streaming and/or locally storing the digital video 116 at the client device 110. Such a website may also enable a user to upload or submit additional videos and any associated metadata to the network 108 using the user interface 112 of the respective client device 110. New videos and associated metadata may then be retrievably stored onto the database 102 by a server 104 in communication with the network 108. Once stored, any user with access to the network 108 may be able to retrieve the new videos and associated metadata from the database 102 and play the videos on the video display 114 in a manner similar to that of the digital video 116 of FIG. 2.
In conjunction with the embodiments disclosed herein, a user viewing a previously stored digital video 116 may be able to record and submit user content 122 to be associated with the digital video 116, as schematically shown for example in FIG. 3. User content 122 may generally include text data, audio data, image data, video data, and/or any other form of data that can be associated with an existing digital video 116 and shared with other users subsequently viewing the digital video 116 over a shared network 108. User content 122 may also include advertisements or promotional video clips that may be related to the content of the digital video 116. While viewing the digital video 116 of FIG. 3, a user may want to insert comments, or user content 122 in the form of text, audio and/or video data, into the digital video 116 such that those comments are viewable to users during subsequent playback sessions of the digital video 116. More specifically, a user may want to record user content 122 to be associated only with certain segments or frames within the digital video 116. Accordingly, the user may selectively reserve one or more frames of the digital video 116 for association with user content 122 using the timeline 120. The user may select the desired frames of the timeline 120 using a pointing device or any other input device through the user interface 112 of the respective client device 110. Furthermore, the temporal locations of the reserved frames may be indicated by visual tags 124, or the like. In the example session of FIG. 3, for example, each visual tag 124 may represent the first of a plurality of frames of the digital video 116 which are associated with some form of user content 122.
Still referring to the recording session of FIG. 3, the user may select any one or more of the visual tags 124 to begin recording user content 122 to be associated with the reserved frames. Moreover, each visual tag 124 may be selected by the user using a pointing device or similar input device through the user interface 112 of the respective client device 110. Once a visual tag 124 is selected, the user may be enabled to record text, audio, image and/or video data using the appropriate combination of input devices at the user interface 112 of the client device 110. For example, the user may record user content 122 in the form of text data using a keyboard or record user content 122 in the form of audio data using a microphone. The user may additionally or alternatively record user content 122 in the form of image or video data using a camera. Once complete, information pertaining to the original digital video 116 and the visual tags 124, or any other temporal reference of the user content 122 recorded at the client device 110, may be transmitted back to the server 104 and stored at the database 102. Additionally, information pertaining to the recorded user content 122 may also be transmitted to the server 104 and stored at the database 102 in association with the original digital video 116. In one refinement, any information pertaining to the user content 122 may be stored directly with any metadata associated with the original digital video 116. In a related refinement, a video proxy for the digital video 116 may be stored on the database 102 if the metadata associated with the digital video 116 cannot be modified, for example, because it is stored at a different location and only accessed via a reference. In such a case, any associated visual tags 124 or the temporal locations thereof may be stored in the video proxy.
Once user content 122 has been successfully recorded within a digital video 116, playback of the user content 122 may be enabled during playback of the original digital video 116, as schematically shown for example in FIG. 4. More specifically, the original digital video 116 may be retrieved and played back by another user accessing the database 102 through the server 104 and the video hosting network 108. In addition to the original digital video 116, the video display 114 may further generate and display visual tags 124 on the timeline 120 representative of previously recorded user content 122. For example, each visual tag 124 may indicate the temporal location of the first of a plurality of previously reserved frames that have already been associated with user content 122. During playback of the digital video 116, previously recorded user content 122 may be displayed or automatically played back once the associated reserved frames of the digital video 116 are reached. For example, once the progress of the digital video 116 as indicated by the timeline 120 reaches the temporal locations marked by the visual tags 124, previously recorded text, audio, image and/or video comments may be simultaneously provided to the immediate user in additional viewing panes 126, or the like. In alternative modifications, previously recorded user content 122 may be played back sequentially. For example, once a visual tag 124 is reached on the timeline 120, the digital video 116 may be paused while previously recorded user content 124 associated with the visual tag 124 is played back. The digital video 116 may automatically resume once playback of the user content 124 is complete. In still further refinements, previously recorded user content 122 may be displayed in a smaller scale within the video display 114 using picture-in-picture technologies, or the like. Selectable thumbnails representative of previously recorded user content 122 may also be displayed to the immediate user so as to enable the user to preview user content 122 before playing back the user content 122. Furthermore, the visual tags 124 themselves may be selectable through the user interface 112 of the respective client device 110 regardless of the progress of the digital video 116. For instance, by clicking on a visual tag 124 using a pointing device, previously recorded user content 122 may be played back to the immediate user on demand.
Turning now to FIG. 5, an exemplary method 128 or algorithm by which a processor 106 of a primary network device 104, such as a server, may enable the recording of user content 122 within a digital video 116 is provided. As an initial step S1, the processor 106 may be configured to generate a visual timeline 120 corresponding to the original digital video 116. Optionally, step S1 may be omitted in embodiments which provide a video display 114 already having a timeline 120. In step S2, the processor 106 may enable a user to select and reserve one or more frames of the digital video 116 using the timeline 120 for the insertion of user content 122. In step S3, the processor 106 may also generate and display one or more visual tags 124 in proximity of the visual timeline 120 so as to temporally indicate the one or more reserved frames associated therewith. Once frames of the original digital video 116 are reserved, the processor 106 may be configured to store user content 122 recorded by the user from a client device 110 into memory or storage device 102 in step S4. In step S5, the processor 106 may associate the user content 122 with the reserved frames of the original digital video 116, and further, store information pertaining to the association within the database 102. In step S6, the processor 106 may additionally be configured to enable playback of previously recorded user content 122 anytime during subsequent playback of the original digital video 116. More specifically, the processor 106 may enable the user content 122 to be sequentially and/or simultaneously played back with the associated digital video 116.
From the foregoing, it will be appreciated that while only certain embodiments have been set forth for the purposes of illustration, alternatives and modifications will be apparent from the above description to those skilled in the art. These and other alternatives are considered equivalents and within the spirit and scope of this disclosure and the appended claims.
