Abstract
Abstract A method and device for keyframe-based video displaying using a video cursor frame in a multikeyframe screen. Keyframe-based displaying of a video presentation enables a user to select among keyframes, and based on the selecting displays a substantially continuous video stream relating to the presentation. In particular, various keyframes are displayed in parallel in a reduced and static video format, and the displaying is controlled as starting from a particular active key frame which subsequently acts as a dynamic cursor frame within the video format. The cursor may be dynamic video plus dynamic audio, dynamic video alone, or static video per interval plus dynamic audio.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
67 words
A method for keyframe-based displaying of a video presentation comprising: displaying various keyframes in parallel in a reduced and static video format selecting among said keyframes to generate a presentation, controlling the presentation as starting from a particular active keyframe which subsequently to the selecting step acts as a dynamic video cursor frame within said format, and displaying a substantially continuous video stream based on said presentation.
Claim 2
Independent Claim
67 words
A method for keyframe-based displaying of a video presentation comprising: displaying various keyframes in parallel in a reduced and static video format selecting among said keyframes to generate a presentation, controlling the presentation as starting from a particular active keyframe which subsequently to the selecting step acts as a dynamic video cursor frame within said format, and displaying a substantially continuous video stream based on said presentation.
Claim 3
Dependent Claim
29 words
A method as claimed in claim 1 , wherein said video is audio-accompanied, and the method allows suppressing of the audio associated to the actual dynamic video cursor frame.
Claim 4
Independent Claim
70 words
A method for keyframe-based rendering of an audio-accompanied video presentation comprising: displaying various keyframes in parallel in a reduced and static video format, selecting among said keyframes to generate a presentation, controlling said rendering as starting from audio associated to a particular active keyframe that subsequently to the selecting acts as a discrete video cursor frame within said format, and outputting a substantially continuous sensory stream based on said presentation.
Claim 5
Independent Claim
70 words
A method for keyframe-based rendering of an audio-accompanied video presentation comprising: displaying various keyframes in parallel in a reduced and static video format, selecting among said keyframes to generate a presentation, controlling said rendering as starting from audio associated to a particular active keyframe that subsequently to the selecting acts as a discrete video cursor frame within said format, and outputting a substantially continuous sensory stream based on said presentation.
Claim 6
Dependent Claim
23 words
A method as claimed in claim 1 , wherein said dynamic video cursor frame freezes upon coinciding with the next displayed keyframe's content.
Claim 7
Dependent Claim
21 words
A method as claimed in claim 4 , wherein upon said coinciding, a next keyframe takes over as dynamic video cursor.
Claim 8
Dependent Claim
16 words
A method as claimed in claim 5 , wherein said taking over is controllable and/or programmable.
Claim 9
Dependent Claim
18 words
A method as claimed in claim 5 , wherein said taking over may involve a programmable mode altering.
Claim 10
Dependent Claim
21 words
A method as claimed in claim 1 , wherein said displayed keyframes substantially take up an entire an actual video format.
Claim 11
Dependent Claim
38 words
A method as claimed in claim 1 , wherein said displayed keyframes take up a fraction of an actual video format, and said dynamic video cursor frame is displayed in an enlarged format with respect to other keyframes.
Claim 12
Dependent Claim
18 words
A method as claimed in claim 1 , which furthermore displays a predetermined set of soft control keys.
Claim 13
Dependent Claim
17 words
A method as claimed in claim 1 , wherein said video presentation is at least digitally labeled.
Claim 14
Dependent Claim
39 words
A method as claimed in claim 1 , wherein keyframes are set in a hierarchical structure and/or various keyframes are allowed to be deleted from display for so joining intervals of said presentation before and behind the deleted keyframe.
Claim 15
Independent Claim
82 words
A device for keyframe-based displaying of a video presentation comprising: a selection means for enabling a user to select among said keyframes, a display device for displaying a substantially continuous sensory stream relating to said presentation, said display device being arranged for displaying various such keyframes in parallel in a reduced and static video format, and a control means for controlling the display device as starting from a particular active keyframe which subsequently acts as a video cursor frame within said format.
Claim 16
Independent Claim
82 words
A device for keyframe-based displaying of a video presentation comprising: a selection means for enabling a user to select among said keyframes, a display device for displaying a substantially continuous sensory stream relating to said presentation, said display device being arranged for displaying various such keyframes in parallel in a reduced and static video format, and a control means for controlling the display device as starting from a particular active keyframe which subsequently acts as a video cursor frame within said format.
Claim 17
Dependent Claim
24 words
A device as claimed in claim 13 , wherein the control means includes a continuous video function and said video cursor frame is dynamic.
Claim 18
Dependent Claim
27 words
A device as claimed in claim 14 , wherein the control means includes an audio component, and said video cursor frame is a discrete video cursor frame.
Claim 19
Dependent Claim
17 words
A device as claimed in claim 13 and arranged for displaying said keyframes at mutually uniform sizes.
Claim 20
Dependent Claim
33 words
A device as claimed in claim 13 and arranged for displaying a video cursor frame in an enlarged size with respect to a plurality of further keyframes in a uniform said reduced format.
