Abstract
An apparatus and method for improved processing of audio and video in the wireless multimedia communication. By setting a SNR estimator in the de-modulator and connecting a PLC trigger between the de-modulator and the PLC module in parallel. The SNR estimator can calculate the signal to noise ratio (SNR) of the wireless signal in the de-modulator directly. The PLC trigger can calculate the losing condition of the digital signal and make the decision whether proceeds the packet loss concealment (PLC) depend on the condition to make the PLC to the highest efficiency.
