Patent ID: 7694318

Claim:
A method for video detection and replacement, the method comprising: receiving an input video signal; creating a temporal sliding window of initial length L seconds and running the sliding window the input video signal, such that at least a portion of the input video signal is captured by the temporal sliding window; comparing a first segment of the portion of the input video signal captured by the temporal sliding window of initial length L seconds to a portion of stored fingerprint data; expanding the temporal sliding window to have an expanded length approximately equal to the length of the stored fingerprint data if the first segment of the portion of the input video signal matches the portion of stored fingerprint data; comparing an expanded segment of the input video signal captured by the expanded window having the expanded length with the stored fingerprint data; and generating an output video signal comprising the input video signal, wherein the expanded segment of the input video signal is replaced with a replacement portion if the expanded segment of the input video signal matches the fingerprint data.
