Patent ID: 6850692

Claim:
A method for retrieving digital video stored in memory comprising: (a) obtaining a specific start time of at least a portion of digital video represented as a t-coordinate; (b) selecting a minimum n-coordinate and a maximum n-coordinate to bound a specific start location of the digital video represented as a n-coordinate; (c) obtaining a minimum t-coordinate based on the minimum n-coordinate; (d) obtaining a maximum t-coordinate based on the maximum n-coordinate; (e) deriving a linear reference between the minimum n and t coordinates and the maximum n and t coordinates; (f) obtaining a reference n-coordinate lying on the linear reference based on the t-coordinate; (g) determining a reference t-coordinate lying on a non-linear monotonic, function, representing digital video stored over time, based on the reference n-coordinate; (h) determining whether the reference t-coordinate is substantially similar to the t-coordinate; (i) when the reference t-coordinate is substantially similar to the t-coordinate, determining that the reference n-coordinate is substantially equal to the n-coordinate, wherein the t-coordinate and the n-coordinate define a starting point of digital video; and (j) retrieving from memory the digital video based on the starting point.
