the like. In this mode, while the VCR is operating to record a
program of interest, the invention determines if a previously
designated advertisement or the like is incoming, and if so
causes the VCR to stop the recording of that advertisement and
rewinds the VCR to the point at which the advertisement began.
Once the advertisement has concluded, the VCR is activated, to
resume the recording of the desired program. A further
understanding of the invention can be achieved from the following
claim.
Claim 21 is illustrative of the claimed subject matter and
reads as follows.
21. A system for controlling a recording device to effect
selective recording of an incoming information stream having a
sequentially ordered plurality of information frames, the system
comprising:
a memory for storing a statistical representation of at
least one memorized information segment, each of said segments
having a plurality of information frames; and
control logic in communication with the memory for
performing sequential pattern matching by comparing a statistical
characterization of at least two of the plurality of incoming
information frames to sequences of information frames in said
memorized information segment, modifying at least one memorized
information segment based on the sequential pattern matching, and
generating a signal for the recording device to effect selective
recording of the incoming information stream based on the
sequential pattern matching.
