Multiple description coding via scaling-rotation transform

A Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding

Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...

Multiple description transform coded transmission over OFDM broadcast channels

We consider image transmission using multiple description transform coding (MDTC) over orthogonal frequency division multiplexed (OFDM) wireless broadcast channels, where the system may not have any feedback on channel gains. We investigate the redundancy allocation in MDTC–OFDM system, physical layer frequency diversity, and decoding strategies to maximize the quality of reconstruction. Via ma...

Optimal and Generalized Multiple Descriptions Image Coding Transform in the Wavelet Domain

In this paper we propose a Multiple Description Image Coding(MDIC) scheme to generate two compressed and balanced rates descriptions in the wavelet domain (Daubechies biorthogonal (9, 7) wavelet) using pairwise correlating transform optimal and application method for Generalized Multiple Description Coding (GMDC) to image coding in the wavelet domain. The GMDC produces statistically correlated ...

An integrated application of multiple description transform coding and error concealment for error-resilient video streaming

Multiple description coding has been shown to provide improved error resiliency for video streaming over error-prone channels. In a typical multiple description codec, the decoder simply reproduces the signal using the received description(s). The optimal reconstruction is obtained from the available description in the sense that the mean squared error is minimized. However, this reconstruction...
