Abstract

A method of determining whether to generate a video refresh request includes receiving a packet and performing at least one of determining whether the received packet contains an error and determining whether a packet prior to the received packet was lost. Responsive to a determination that the received packet contains an error, an error index is increased. Responsive to a determination that a packet prior to the received packet has been lost, the error index is increased. Responsive to a determination that the received packet does not contain an error and that a packet prior to the received packet has not been lost, the error index is decreased.
