Playout is the process of regenerating the stream based on the playout timestamp.
The playout is an exact offset to the ingress stream-recovered clock and serves as playout time for the video ISA. Because the timestamp is used for buffer playout, CBR, capped VBR, and VBR streams are all supported without pre-configuration. The playout buffer mechanism effectively removes network-induced jitter and restores the output to the rate of the original encoder.
