WebAbstract: Channel-aware mode is one novel technique in EVS codec to improve error robustness for VoIP, which uses forward error correction by transmitting re-encoded … WebThe EVS channel aware mode transmits redundancy in-band as part of the codec payload as opposed to transmitting redundancy at the transport layer (e.g., by including multiple packets in a single RTP payload). Including the redundancy in-band allows the transmission of redundancy to be either channel controlled (e.g., to combat network ...
WebEVS channel aware mode is specifically created for reliable speech transmit under especially bad network conditions such as high packet loss, jitter, etc. Channel aware is available in two configuration modes: EVS WB 13.2 and EVS S-WB 13.2. www.spirent.com Testing the EVS Codec WebThe EVS Channel Aware mode leverages these ACELP and TCX core advancements for primary frame encoding . Additionally, as the partial copy uses varying number of bits across frame s, the primary ...
