Abstract :
In multiple reference frame coding the compression efficiency of the codec improves with increasing the number of reference frames. However, it is shown that when cyclic intra-refresh lines are used to prevent error propagation, increasing the number of reference frames reduces the received video quality in the presence of transmission errors.
