Multiple description coding encodes a source for transmission over a communication system with multiple channels, which will generate two or more related bitstreams. When errors occur, the corrupted (lost) data can be recovered from the other bitstreams. In this study, a new multiple description motion compensation (MDMC) video coding scheme for lossy packet networks is proposed. In the propose...

IEEE defines various modulation schemes for WiMAX i.e. QPSK, BPSK, 16 QAM and 64 QAM. This model will examine Internet Protocol Television (IPTV) performance over Fixed WiMAX system taking many combinations of digital modulation. The performance will involve many key system parameters, which will involve the variation in the path loss, video coding, different rated codes, scheduling service cla...

With the explosive growth of video applications over the Internet, many approaches have been proposed to stream video effectively over packet switched, best-effort networks. A number of these use techniques from source and channel coding, or implement transport protocols, or modify system architectures in order to deal with delay, loss, and time-varying nature of the Internet. In this paper, we...

Multiple description coding addresses the problem of encoding a source signal into two or more sub-streams. Each sub-stream is assumed to be transmitted over an independent path. However, multiple independent paths may not be available, and for most cases only a single path can be used. The scheduling of these descriptions over a single path is still problematic because of the bursty packet los...

Introduction Increased bandwidth of wireless technologies motivated delivery of video over wireless networks. H.264 compressed video source, applied to video coding layer (VCL) for high compression representation of video content, has a number of error resilience tools. Data partitioning (DP) creates partitions on highest data structure called slices. By enabling DP technique, VCL divides origi...

Wavelet-based techniques are becoming increasingly widely used for encoding image and video signals. Wavelet-coded video streams are highly compressible and have considerable amount of error resilience built-in. These two features are critical to the performance of a real-time video coding system that communicates over a lossy transmission medium. A wavelet-based adaptive coding scheme is propo...

With provisioning of broadband access for mass market—even in wireless and mobile networks—multimedia content, especially real-time streaming of highquality audio and video, is extensively viewed and exchanged over the Internet. Quality of Experience (QoE) aspects, describing the service quality perceived by the user, is a vital factor in ensuring customer satisfaction in today’s communication ...

The actual performance of video delivery over wireless networks is best captured through experimental studies over real testbed, which is crucial to uncover the technical problems and practical challenges of realizing the proposed video delivery techniques. Network coding (NC) provides a paradigm shift to optimize the network resources for enhancing the video quality as a result of delivery ove...

Performance analysis of multilevel unequal error protection (UEP) codes with wavelet video compression for wideband code division multiple access (W-CDMA) over additive white Gaussian noise (AWGN) and Rayleigh fading channels are achieved and evaluated. Wavelets possess a dominant method and high quality for compressing video sequence. A spatially scalable video coding framework of MPEG2 in whi...
