چکیده

We propose an optimal Multiple Description (MD) video coding technique with 3D-Set Partitioning in Hierarchical Tree (3D-SPIHT) algorithm. Multiple Description Coding (MDC) technique generates multiple bitstreams of the video content and has useful applications in packet video networks and error-prone networks. We describe a twodescription MDC system that embraces rate-distortion optimization to generate two balanced, efficient descriptions. Experimental results on a variety of test sequences show that the proposed method achieves a significant improvement in compression performance compared to existing methods.

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...

3-D multiple description video coding for packet switched networks

Multiple description coding (MDC) schemes have become popular as robustness tools in packet switched networks where multiple paths with varying packet loss rates are available. In this paper we propose a new MDC scheme for video using 3D wavelet decomposition. The spatio-temporal coefficients are then grouped using either a random, uniform scheme or a hierarchical scheme. The descriptions are c...

H.264-Based Resolution, SNR and Temporal Scalable Video Transmission Systems

This paper presents a novel H.264-based video coding scheme for a scalable delivery system which operates over heterogeneous networks and distributes real-time streaming video to diverse types of clients. The video coding scheme is a hybrid combination of discrete wavelet transform (DWT) and H.264. In the algorithm, an input video sequence is first decomposed into a fundamental sequence and a n...

Unbalanced multiple description wavelet coding for scalable video transmission

Scalable video coding (SVC) and multiple description coding (MDC) are the two different adaptation schemes for video transmission over heterogenous and best-effort networks such as the Internet. We propose a new approach to encode video for unreliable networks with rate adaptation capability. Our proposed method groups 3D discrete wavelet transform coefficients in different descriptions and app...

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 ...
