Smart SoftPhone Device for Networked Audio- Visual QoS/QoE Discovery & Measurement
Jinsul Kim · InTech eBooks · 2008
The demand on the guaranteed QoS/QoE of the flexible audio-visual content through the heterogeneous networks and the display heterogeneous terminals will increase as much as the MoIP service has been developed rapidly in residential and business communication markets. ? In this chapter, several related active research issues of Mobile IPTV service are highlighted and some new research directions have been pointed out. ? Provide critical message procedures applying RTCP-XR based packet structures BTs to manage call session with quality factors such as jitter, delay, loss, etc. ? Design management module for call session and for quality reporting using SoftPhone. ? Present QoS/QoE-factors transmission control mechanism ? Assess voice quality with a performance analysis of the PLC algorithms ? Derive video quality guaranteed technologies that enable end-to-end personal mobile broadcasting service in a heterogeneous environment. ? Ability to correlate the impact of networking resource, terminal capability, and user profile at each of the media stream applications. Finally, our proposed methods of transmission procedure and management scheme using SoftPhone are very useful to manage QoS/QoE audio-visual quality through IP network. Also, hybrid objective metric is very useful for user perceived QoE-aware video quality measurement.
