Abstract
Abstract In a system wherein a continuous signal is divided into a plurality of discrete segments each consisting of a plurality of signal samples, a predetermined number of the last signal samples of one segment are repeated as the first signal samples of the next segment. The predetermined number is selected to correspond to a time duration greater than at least a major portion of the transients introduced as a result of dividing the continuous signal into segments. The continuous signal can thus be reconstructed from the segments without discontinuities and without the unwanted transients.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
In a method of segmenting a continuous signal to permit the subsequent reconstruction of the continuous signal without introducing transients developed during processing of the segmented signals, the steps of: dividing a continuous signal into discrete segments, each of said segments being comprised of the plurality of signal samples, and repeating one or more of the last signal samples of a signal segment as the first signal samples of the next signal segment, the number of signal samples repeated corresponding to a time duration greater than the time duration of transients introduced during the processing of the segmented signals.
Claim 2
Dependent Claim
99 words
In a method of segmenting a continuous signal to permit the subsequent reconstruction of the continuous signal without introducing transients developed during processing of the segmented signals, the steps of: dividing a continuous signal into discrete segments, each of said segments being comprised of the plurality of signal samples, and repeating one or more of the last signal samples of a signal segment as the first signal samples of the next signal segment, the number of signal samples repeated corresponding to a time duration greater than the time duration of transients introduced during the processing of the segmented signals.
Claim 3
Dependent Claim
21 words
A method as claimed in claim 1 further including the step of time compressing said signal segments for storage or transmission.
Claim 4
Dependent Claim
36 words
A method as claimed in claim 1 further including the step of reconstructing said continuous signal by reproducing said segments in a serial, continuous manner without repeating the portion of each segment corresponding to said transients.
Claim 5
Dependent Claim
15 words
A method as claimed in claim 1 wherein said continuous signal consists of audio information.
Claim 6
Dependent Claim
34 words
A method as claimed in claim 4 further including the step of converting the bandwidth of the segments of audio information from audio bandwidth to video bandwidth for transmission and storage on video apparatus.
