RTP implementation of a packet loss concelament method for networked music performance: A Networked Music Performance (NMP) is a real-time Internet application, in which different performers or musicians hold the music show remotely and interact with each other going through communication networks. For enabling musicians play simultaneously in distance, a low latency transmission is strictly required. Therefore, to minimize the end-to-end delay, uncompressed, bidirectional audio streams are used in some typical implementations of NMP applications, along with UDP running at transport layer. However, due to the best effort mechanism of the Internet, it is hard to avoid the network jitter and data loss.
