 ## Segmentation  
 The default behavior of the segmenter is to estimate the theoretical start time of each segment based on target segment duration, and start a new segment when a packet with SAP type 1,2,3 or 4 with time greater than the theoretical time is found.  
 This behavior can be changed to find the best SAP packet around a segment theoretical boundary using [sbound](#sbound):
