Abstract :
Real-time multimedia communication due to its stringent delay requirements needs low delay PLC (packet loss concealment) methods to reduce the effect of lost packets. For audiovisual communications several PLC methods are utilized such as zero substitution or waveform substitution, we compare zero substitution and waveform repetition for a Gaussian source on the Gilbert-Elliott channel model. This allows to model the decrease of distortion with increasing buffer length
