Patent ID: 7540011

Claim:
A system for allowing a user to select a video sequence from stored video data from multiple cameras, said stored video being time-stamped, the system comprising: a server component configured to receive a request specifying a time range, a desired spacing, and at least one camera from said multiple cameras, to dynamically process the stored video data to identify a subset of frames recorded from said at least one camera and having time-stamps that span the specified time range at the specified spacing, to generate one handle for each frame, that can be used to retrieve said each frame, and to send a reply response containing the generated handles, wherein the system is configured to cache video data of said subset of frames in a data cache, and wherein the system is configured to perform spatial or temporal reconstruction if signals of the subset of frames are sampled with different sampling rates and if a portion of the data for the selectable image sequence was previously stored in the data cache.
