Abstract
Abstract A system and method for browsing dynamic video information over a network includes selecting a small subset of frames from video shots and collections, using a threshold difference between two compared frames, to capture the dynamic content. Further selection and interleaving the selected frames within the shots and collections can be done to satisfy resource constraints like utilization of bandwidth. Interleaving is performed in storage and transmission of the frames to improve presentation of video information and to simultaneously display selected frames on a computer display to convey the dynamic of video. The system and method permit a dynamic summary of video information to be sent to a user over a network, while reducing resources (bandwidth) used by the network for the amount of information presented to the user.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
116 words
A computer system comprising: a memory storage containing one or more multimedia collections, each of the collections having one or more multimedia shots, each of the shots having one or more frames; a selection process that selects a subset of one or more of the frames by traversing the frames of each of one or more of the shots in a time direction, any pair of adjacent frames in the subset having an intensity difference that is the same as the intensity difference between any other pair of adjacent frames in the subset, within a tolerance; and a second selection process that selects a second subset of frames from the subset to satisfy a resource constraint.
Claim 2
Dependent Claim
116 words
A computer system comprising: a memory storage containing one or more multimedia collections, each of the collections having one or more multimedia shots, each of the shots having one or more frames; a selection process that selects a subset of one or more of the frames by traversing the frames of each of one or more of the shots in a time direction, any pair of adjacent frames in the subset having an intensity difference that is the same as the intensity difference between any other pair of adjacent frames in the subset, within a tolerance; and a second selection process that selects a second subset of frames from the subset to satisfy a resource constraint.
Claim 3
Dependent Claim
20 words
A system, as in claim 1, where the resource constraint limits the total number of frames in the second subset.
Claim 4
Dependent Claim
32 words
A system, as in claim 2, where the constraint is any one or more of the following: a user response, a lack of user response, a bandwidth limitation, and a storage limitation.
Claim 5
Dependent Claim
28 words
A system, as in claim 2, where each of the adjacent frames in the second subset differs in intensity multiple of the intensity threshold within a second tolerance.
Claim 6
Dependent Claim
18 words
A system, as in claim 1, where the direction is any one of increasing time and decreasing time.
Claim 7
Dependent Claim
29 words
A system, as in claim 1, where the intensity difference is determined by any one of the following: a pixel to pixel comparison and a histogram differencing between frames.
Claim 8
Dependent Claim
18 words
A system, as in claim 1, where the selection process further stores the selected frames in an order.
Claim 9
Dependent Claim
23 words
A system, as in claim 7, where the order is the order of selection as the frame is traversed in the time direction.
Claim 10
Dependent Claim
42 words
A system, as in claim 7, where the order is an interleaved order, the interleaving order adjacently storing one or more of the frames that are not adjacent in the order of selection as the frame is traversed in the time direction.
Claim 11
Dependent Claim
51 words
A system, as in claim 9, where the interleaving process groups frames of the subset of frames into one or more groups so each of the members of the group differ in intensity from an adjacent member of the group by a multiple of the intensity threshold within an intensity tolerance.
Claim 12
Dependent Claim
20 words
A system, as in claim 7, in which the stored frames from all the collections are transmitted in the order.
Claim 13
Dependent Claim
22 words
A system, as in claim 7, in which the stored frames from all the collections are transmitted in the transmitted interleaved order.
Claim 14
Dependent Claim
35 words
A system, as in claim 12, in which the transmitted interleaved order is transmitted at least one frame from each shot in the collection before transmitting a next frame from any shot in the collection.
Claim 15
Dependent Claim
30 words
A system, as in claim 12, in which the transmitted interleaved order is transmitted at least one frame from each collection before transmitting a next frame from any other collection.
Claim 16
Dependent Claim
33 words
A system, as in claim 14, where the transmitted interleaved order transmits at least one frame from each shot in the collection before transmitting a next frame from any shot in the collection.
