A video coding paradigm called PRISM (Power-efficient, Robust, hIgh compression, Syndrome-based Multimedia coding) built on distributed source coding principles has been recently proposed in [1]. In this paper, we study a scalable version of PRISM which addresses both spatial and temporal scalability. The proposed codec inherits the main attributes of the PRISM architecture, namely increased ro...

Wireless video streaming is a challenging task due to limited bandwidth and error-prone characteristics of the wireless channels. In order to ensure high quality wireless video streaming, error control techniques such as forward error correction (FEC) is needed. It is well-known that, in mobile radio channels, errors are not limited to single bit errors but tend to occur in bursts. In order to ...

The fault current development in a circuit breaker during a pole-to-ground fault is analyzed for a generic multiterminal HVDC system based on Voltage Source Converters. The paper aims to contribute to the current discussion of which requirements on breaking time and peak current HVDC circuit breakers need to fulfill in such networks either based on OHLs or cables. Therefore, the fault current i...

In this paper, mathematical bases for non-adaptive joint source network coding of correlated messages in a Bayesian scenario are studied. Specifically, we introduce one-step Quantized Network Coding (QNC), which is a hybrid combination of network coding and packet forwarding for transmission. Motivated by the work on Bayesian compressed sensing, we derive theoretical guarantees on robust recove...

In this paper; we present a FEC-based end-to-end error control scheme for video streaming over packet loss networks. We propose a novel robust video streaming system in which an interleaving is applied to the compressed bitstream before channel coding. The application of such preinterleaving is able to improve the perlformatice of video streaming over packet loss networks because pre-interleavi...

Network coding broadly refers to the processing of data at the intermediate nodes of a network in addition to routing data from source to destination. The theoretical framework for network coding was first provided by Ahlswede et al. in [1]. In this paper, the authors demonstrate the benefits of network coding over mere routing in improving the throughput of a single-source multicast transmissi...

We propose a novel packetization and variable bitrate compression scheme for DSR source coding, based on the Group of Pictures concept from video coding. The proposed algorithm simultaneously packetizes and further compresses source coded features using the high interframe correlation of speech, and is compatible with a variety of VQ-based DSR source coders. The algorithm approximates vector qu...
