Block-based video coders rely on motion compensated block prediction for more data compression. With the introduction of video coding over packet-switched networks such as the Internet and the resulting packet loss that occurs on congested networks, coding mode selection for each macro-block is significant in determining the overall distortion on the decoded video sequence. In this work, we exa...

The use of forward error correction (FEC) coding is often proposed to combat the effects of network packet losses for error-resilient video transmission on packet-switched networks. On the other hand, path diversity has recently been proposed to improve network transport for both singledescription (SD) and multiple-description (MD) coded video. In this work we model and analyze an SD coded vide...

Network coding is a new technique in the field of information theory and coding theory. This emerging technique offers great benefits in the communication networks such as increased throughput and energy savings. In this paper, we evaluate network coding for video transmission scenarios. In these scenarios, the source nodes encode the video packets, while the intermediate nodes implement networ...

Current advances in technology mean multimedia applications like video is becoming increasingly more important in mobile ad hoc networks. To transmit video information quickly and without errors in networks with different packet loss rates is a key technical problem. In this paper, the encoding problem of rate distortion optimization with JSVM (Joint Scalable Video Model) is studied according t...

The transport of a digital video with satisfactory quality over packet networks is still a challenging issue. Video Flows have contents with different importance during the coding phase, while packet networks do not provide native mechanisms that can prioritize the more important contents. In this work, we present a metric of quality that permits the evaluation of received videos, qualitatively...

With the prevalence of wireless video applications, QoS of wireless video transmission in resource-limited wireless networks attract more and more researchers’ attention. In network layer, how to perform video packet assignment in multipath routing is a key issue. In this paper, we develop a simple but efficient, priority based dynamic assignment algorithm for multipath routing. The idea of thi...

We consider transmission of video for real-time display over a network offering differentiated services. In such a network, the probability of loss for each video packet is determined by the service class assigned to it. Using information about the error concealment strategy at the decoder and the QoS status of the network, we jointly consider the selection of source coding parameters and packe...

With the rapid improvements in digital communication technologies, distributing high-definition visual information has become more widespread. However, the available technologies were not sufficient to support the rising demand for high-definition video. This situation is further complicated when the network resources such as the available bandwidth fluctuates, or packet losses occur during tra...

The JVT/H.26L video coding scheme conceptually consists of a Video Coding Layer (VCL) responsible mainly for coding efficiency and a Network Abstraction Layer (NAL) that supports video specific transport features for a variety of networks. This paper describes the H.26L/JVT NAL in general, including the parameter set concept and the transport over packet-based and bit-stream oriented networks. ...
