Time-constrained error recovery is an integral component
of reliable low-delay video applications. Regardless of
the error-control method adopted by the application,
unacknowledged or missing packets must be quickly
identified as lost or delayed, so that necessary timely
actions can be taken by the server/client. Historically, this
problem has been referred to as the retransmission timeout
(RTO) estimation. Earlier studies show that existing RTO
estimators suffer from either long loss detection times or
a large number of pre-mature timeouts. The goal of
this study is to address these problems by developing an
adaptive RTO estimator for high-bitrate low-delay video
