State estimation over packet dropping networks using multiple description coding
For state estimation over a communication network, efficiency and reliability of the network are critical issues. The presence of packet dropping and communication delay can greatly impair our ability to measure and predict states. In this paper, multiple description (MD) codes, a type of network source codes, are used to compensate for this effect on Kalman filtering. We consider two packet dr...
متن کاملA 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...
متن کاملStandard-Compliant Multiple Description Video Coding over Packet Loss Network
An effective scheme of multiple description video coding is proposed for transmission over packet loss network. Using priority encoding transmission, we attempt to overcome the limitation of specific scalable video codec and apply FEC-based multiple description to a common video coder, such as the standard H.264. Firstly, multiple descriptions can be generated using temporal downsampling and th...
متن کامل3-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...
متن کاملMultiple Description Scalable Coding for Error Resilient Video Transmission over Packet Networks
Two types of scalabilities exist in current scalable video streaming schemes: (1) nested scalability, in which different representations (i.e., descriptions) of each frame are generated using layered scalable coding and have to be decoded in a fixed sequential order, and (2) parallel scalability, which is used in multiple description coding (MDC) where different descriptions are mutually refina...
