Spatial Multiple Description Coding for Scalable Video Streams
The need for adapting video stream delivery over heterogeneous and unreliable networks requires self-adaptive and error resilient coding.Network bandwidth fluctuations can be handled bymeans of a video coding schemewhich adapts to the channel conditions. However, packet losses which are frequent in wireless networks can cause a mismatch during the reconstruction in the receiver end and result i...
متن کاملScalable multiple description coding of video sequences
In this paper, we address the problem of robust transmission of compressed visual information and propose two transmission schemes based on Multiple Description Scalable Coding (MDSC). In both schemes, we generate four spatial subsequences from the original video stream, by subsampling in both horizontal and vertical directions. Then, each description is encoded using two subsequences using the...
متن کاملUnbalanced 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...
متن کاملMultiple Description Scalable Coding for Video Transmission over Unreliable Networks
Developing real time multimedia applications for best effort networks such as the Internet requires prohibitions against jitter delay and frame loss. This problem is further complicated in wireless networks as the rate of frame corruption or loss is higher in wireless networks while they generally have lower data rates compared to wired networks. On the other hand, variations of the bandwidth a...
متن کاملScalable Multiple Description Coding for Video Distribution in P2p Networks
In this paper we present and evaluate a method for video distribution through a peer-to-peer (P2P) network using Multiple Description Coding in a multicast tree. Our method solves the problem of serving many clients with heterogeneous bandwidths. Every node forwards descriptions to other nodes. Nodes that have sufficient bandwidth are then able to receive more descriptions, and thereby to incre...
