Due to the lightweight measurement and no access to the media signal, the packet-layer video quality assessment model is highly preferable and utilized in the non-intrusive and in-service network applications. In this paper, a novel packet-layer model is proposed to monitor the video quality of Internet protocol television (IPTV). Apart from predicting the coding distortion by the compres‐ sion...

In this paper, we study real-time scalable video broadcast over wireless networks using instantly decodable network coding (IDNC). Such real-time scalable videos have hard deadline and impose a decoding order on the video layers. We first derive the upper bound on the probability that the individual completion times of all receivers meet the deadline. Using this probability, we design two prior...

We propose to improve the packet loss resilience of scalable video coding. An algorithm for optimal coding mode selection for the base and enhancement layers is developed, which limits error propagation due to packet loss, while retaining compression eÆciency. We rst derive a method to estimate the overall decoder distortion, which includes the e ects of quantization, packet loss and error conc...

Scalable video coding is a technique which allows a compressed video stream to be decoded in several different ways. This ability allows a user to adaptively recover a specific version of a video depending on its own requirements. Video sequences have temporal, spatial and quality scalabilities. In this work we introduce a novel fully scalable video codec. It is based on a motion-compensated te...

With the explosive growth of video applications over the Internet, many approaches have been proposed to stream video effectively over packet switched, best-effort networks. Many use techniques from source and channel coding, or implement transport protocols, or modify system architectures in order to deal with delay, loss, and time-varying nature of the Internet. In our previous work , we prop...

Highly scalable wavelet video codec is proposed for Internet video streaming applications based on the simplified JPEG-2000 compression core. Most of existing video solutions are utilizing fixed temporal grouping structure, resulting in quality degradation due to structural mismatch with inherent motion and scene change. Thus, by adopting the adaptive frame grouping based on the fast scene chan...

We present a new multiple-description coding (MDC) method for scalable video, designed for transmission over error-prone networks. We employ a redundant motion-compensated scheme derived from the Haar multiresolution analysis, in order to build temporally correlated descriptions in a t+2D video coder. Our scheme presents a redundancy which decreases with the resolution level. This is achieved b...

In this paper, we address the problem of enabling robust interactive video coding and transmission over heterogeneous wired-towireless IP networks. We propose the use of an FEC coding scheme employing Reed-Solomon (RS) codes and rate-compatible punctured convolutional (RCPC) codes to protect the video data from packet loss and bit errors, respectively. Furthermore, we apply an end-to-end archit...

With future vehicles equipped with processing capability, storage, and communications, vehicular networks will become a reality. A vast number of applications will arise that will make use of this connectivity. Some of them will be based on video streaming. In this paper we focus on HEVC video coding standard streaming in vehicular networks and how it deals with packet losses with the aid of Ra...

We present a new algorithm to dynamically identify perceptually important regions in pictures of a video sequence. For each macroblock, the distortion that its loss would cause at the decoder is computed. High-distortion macroblocks are then grouped together into slices to be protected with forward error correction or to be sent as “premium” packets. We developed the approach for the case of vi...
