Proposed Media Signal Sharing Scheme Through NGN for Service Overlay Multimedia Framework
The media sharing technique in the signal for multimedia communication is one of the necessary research issues to provide the quality-guaranteed services over IP-based NGN (Next Generation Network). This paper proposes noisy signal reduction method with considering packet loss for multi-user connected multimedia communication. In order to reduce noisy signal without packet distortion efficiently for applying to All-IP based convergence environment, we provide a shared signal reduction and recovery scheme which use an optimized Wiener filtering technique based on input-SNR estimation with adaptive both-side information utilization according to the average magnitude variation across the frames. Also, this paper presents the policy-based service overlay IPTV framework for user experiences in the Open IPTV. We suggest the EPG ought to be selectable in the Open IPTV framework for requirements. The framework is proposed with the basis of the ITU-T IPTV NGN framework with IMS (IP Multimedia Subsystem).
