DEEP TAGS CLASSIFICATION FOR DIGITAL MEDIA PLAYBACK

Robert Garner

Ernesto Morales

BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present invention relates to the field of digital media playback and more

particularly to scene indexing in a digital film.

Description of the Related Art

[0002] People began watching films and movies in the nineteenth century. With the

advent of video cassettes and at-home players, such as videocassette recorders (VCRs),

people now enjoy the viewing of movies from the comfort of their homes. A distinct

advantage of viewing film at home on a playback device like a VCR is that the viewer

can select a particular portion or scene of the film for viewing without being required to

view the film in its entirety, which would be the case if the film were viewed in a theater

environment. In order to watch a specific scene of a film using a VCR, the scene must

first be located. Mechanically, this requires, a tedious trial and error struggle with fast-

forward and rewind to locate the desired scene.

[0003] The advancement of technology and replacement of VCR technology with

Digital Video Disc or Digital Versatile Disc (DVD) technology facilitated the finding of

a specific scene in digital media easier through the use of a scene selection menu option

in the main DVD menu. The scene selection option permits a display of an index of

scenes by name in response to the selection of which directs the playback of the DVD from the selected scene. Necessarily then, the scene selection option of a DVD narrows the number of scenes necessary to watch before finding a specific scene.

[0004] With the internet and electronic distribution of content, people now can watch all types of media, including, but not limited to, film and television shows over the internet. Most media players on the internet provide playback options, including a slider user interface control to control the frame being viewed and played back, but a user must still use trial and error to find a specific scene or specific part of a movie. Combined with scene selection type functionality, the end user can locate a known scene by name very rapidly. In the absence of a priori knowledge of the desired scene, however, locating scenes of a particular type remains an ad hoc, trial and error process not much different from that required by a VCR. Yet, with access to so much media content over the internet, media watchers only want to watch certain scenes of a movie or television show relating to a specific theme, such as car crash scenes for racing enthusiasts, instances of fumbles for football enthusiasts, or dance scenes in a movie or television show for dance enthusiasts.

BRIEF SUMMARY OF THE INVENTION

[0005] Embodiments of the invention provide for a system, a computer program product, and a method for deep tag navigation of digital media. In an embodiment of the invention, a method for deep tag media playback is provided. The method includes activating a user interface control for a media player executing in memory of a computer and correlating the user interface control to a classification of content type for digital media. A starting frame of digital media loaded for playback in the media player is determined for the correlated classification and the digital media is indexed to the starting frame in the media player. Finally, playback of the digital media is directed in the media player beginning with the starting frame. Optionally, a proximity event can be detected for the user interface control. In response, a thumbnail image is generated based on the starting frame and the thumbnail image is displayed in proximity to the user interface control.

[0006] Another embodiment of the invention provides a media playback system configured for deep tag navigation of digital media. The system can include a computer configured to support a content browser and a media player. The system can further include a deep tags media playback classifications module. The deep tags media playback classifications module can include program code for selecting a classification, determining a starting frame for the selected classification, indexing to the starting frame, and directing playback of the media. Also, the media playback classifications module can include program code for generating a thumbnail image based on the starting frame and displaying the thumbnail image.

[0007] Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0008] The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:

[0009] Figure 1 is a pictorial illustration of a process for deep tag playback of digital media;

[0010] Figure 2 is a schematic illustration of a media playback computer system configured for deep tag playback of digital media;

[0011] Figure 3A is a flow chart illustrating a process for deep tag media playback; and,

[0012] Figure 3B is a flow chart illustrating a process for thumbnail imagery display during deep tag media playback.

DETAILED DESCRIPTION OF THE INVENTION

[0013] In accordance with an embodiment of the invention, deep tag media playback can be provided. In deep tag media playback, different user interface controls can be arranged in conjunction with a display of a media player through which digital media can be played back. Each user interface control can be defined according to a different classification of scene type and linked to an index of a scene in the digital media that is consistent with the classification. Each user interface control further can be configured to respond to activation by directing playback of the digital media in the display from a corresponding indexed scene. Optionally, each user interface control can be further configured to respond to a proximity or selection event by directing rendering of a thumbnail image of the corresponding indexed scene. In this way, though a viewer may not know of specific scene content in digital media, the viewer can elect to advance viewing of the digital media to scene content consistent with a particular classification of scene type, such as "car crashes", "fumbles", "dancing scenes" and the like.

[0014] In further illustration, Figure 1 pictorially shows a process for deep tag playback of digital media. As shown in Figure 1, digital media 110 such as a film or video, is composed of a multiplicity of frames 120A, 120B, 120C, 120D. The frames 120A, 120B, 120C, 120D can be grouped into different classifications 130 based on the nature of the images or content contained in the frames 120 A, 120B, 120C, 120D. For example, a classification 130 can include "fighting" for frames 120A, 120B, 120C, 120D containing imagery of a fight, or "interception" for frames 120A, 120B, 120C, 120D depicting the interception of a football during a football game. Each of the different classifications 130 can be associated with a control element (not shown) placed in proximity to a media player 140 configured to play back the digital media 110 such that the activation of the control element results in a selection of the particular one of the classifications 130 associated with the control element.

[0015] In response to the selection of a particular one of the classification 130 by way of the activation of a corresponding control element, the frames 120A, 120B, 120C, 120D associated with the selected one of the classifications 130 can be played back in the media player 140. Optionally, as a pointing device 150 comes into proximity of a user interface control for a selected one of the classifications 130, or when a user interface control for a selected one of the classifications 130 is activated, a thumbnail image 160 of one or more of the frames 120A, 120B, 120C, 120D corresponding one of the

classifications 130 can be rendered in a thumbnail imagery display 165 in association with the user interface control for the selected one of the classifications 130.

[0016] The process described in connection with Figure 1 can be implemented in a media playback computer system. In further illustration, Figure 2 is a schematic illustration of a media playback computer system configured for deep tag playback of digital media. The system can include a computer 200. The computer can include at least one processor 210 and memory 205. An operating system 215 can execute in the memory 205 of the computer 200 by at least one processor 210 of the computer 200. The operating system 215 can host the operation of a content browser 220, such as a web

browser or an Internet browser. Further, a media player 225 can execute in conjunction with the display of content in the content browser 220.

[0017] Of note, a deep tags media playback classifications module 230 can execute in the memory 205 of the computer and can be coupled to the media player 225. The deep tags media playback classifications module 230 can include program code that when executed by at least one processor 210 of the computer 200 responds to the activation of a user interface control 245 for a display 240 of the media player 225 playing back frames of digital media 250, by determining a corresponding classification for the activated one of the user interface controls 245 and for directing the media player 225 to playback those frames of the digital media 250 associated with the corresponding classification. Further, the program code of the deep tags media playback module 230 when executed by at least one processor 210 of the computer 200 can render a thumbnail image of one or more frames of the digital media 250 corresponding to a particular classification in response to a mouse-over event or a selection event for a user interface control 245 associated with the particular classification so as to provide a "preview" of the frames of the digital media 250 for the particular classification.

[0018] In yet further illustration of the operation of the deep tags media playback module 230, Figure 3A is a flow chart illustrating a process for deep tag media playback. Beginning in block 305, a user interface control corresponding to a particular

classification can be selected. In block 310, the starting frame (the first frame) for the digital media associated with the particular classification is determined. For instance, a table can be maintained correlating a selected classification with a starting frame of specific digital media. Optionally, the final frame of the digital media for the user-selected classification is determined. Electively, the total length of the digital media for the user-selected classification is determined. The starting frame is indexed in a digital media player in block 315. In block 320, the digital media associated with the user-selected classification is played back from the starting frame. Finally, in block 325, the play back of the digital media associated with the user-selected classification is displayed in the media player.

[0019] Turning now to Figure 3B, a flow chart is provided illustrating a process for thumbnail imagery display during deep tag media playback. Beginning in block 350, a proximity event such as a mouse-over or selection event for a user interface control corresponding to a particular classification is detected. In block 355, at least one frame associated with the particular classification is determined. In block 360, the frame associated with the user-selected classification is indexed. In block 365, a thumbnail image of the frame associated with the particular classification is generated. For example, the thumbnail image can include a frame associated with the particular classification, such as the first frame or one or more following frames from the first frame. Finally, in block 370, the thumbnail image is displayed in a thumbnail imagery display in association with the user.
