the time between two consecutive frames in the incoming stream, while
Outgoing Stream Interarrival Time (seconds) species the time between
two consecutive video frames in the outgoing stream. The time when the
next frame is generated is computed by adding the “interarrival” time to
the time when the previous video frame was generated and sent from the
video application to the lower layer. The frame arrival frequency or rate is
inversely proportional to the frame interarrival time (e.g., an arrival fre-
quency of 10 frames per second corresponds to a frame interarrival time of ...
