Perceptual Optimization of Playout Buffer in Voip Applications
Packet delay and loss are two essential problems to real-time voice transmission over IP networks. In the proposed system, the playout delay is adaptively adjusted based on a simplified version of the conversational-quality E-model. Perceptual-based buffer design is formulated as an unconstrained op...

| description | Packet delay and loss are two essential problems to real-time voice transmission over IP networks. In the proposed system, the playout delay is adaptively adjusted based on a simplified version of the conversational-quality E-model. Perceptual-based buffer design is formulated as an unconstrained optimization problem leading to a better balance between end-to-end delay and packet loss. Experimental results show that the proposed playout buffer algorithm can achieve the optimum perceived speech quality under various network conditions. |
