Offset Trace-Based Video Quality Evaluation after Network Transport
Video traces contain information about encoded video frames, such as frame sizes and qualities, and provide a convenient method to conduct multimedia networking research. Although widely used in networking research, these traces do not allow to determine the video quality in an accurate manner after networking transport that includes losses and delays. In this work, we provide (i) an overview o...
متن کاملOffset Distortion Traces for Trace-Based Evaluation of Video Quality after Network Transport (Extended Version)
Video traces containing the sizes and (PSNR) qualities of the individual frames of a video encoding are a convenient video representation for the evaluation of video networking mechanisms. These video traces can be used to find the frame loss probabilities of a lossy networking mechanism, but can not give the PSNR video quality after lossy network transport. To date the video quality after loss...
متن کاملUsing Network Simulators with Video Traces
Video traces for the evaluation of network performance are publicly available today. With the content–dependence of video sequences, the generation of an universal video source model is not possible. As the video models to date all use the video frame sizes for the adjustment of the model parameters, video traces are needed for the application of these models. The design and layout of networks,...
متن کاملA Framework for Advanced Video Traces: Evaluating Visual Quality for Video Transmission Over Lossy Networks
Conventional video traces (which characterize the video encoding frame sizes in bits and frame quality in PSNR) are limited to evaluating loss-free video transmission. To evaluate robust video transmission schemes for lossy network transport, generally experiments with actual video are required. To circumvent the need for experiments with actual videos, we propose in this paper an advanced vide...
متن کاملH . 264 / AVC and SVC Video Trace Library : ∗
There are three ways to characterize encoded video for the purpose of networking research: (i) video traffic model, (ii) video bit stream, and (iii) video traffic trace. Video traffic models strive to capture the essential properties of the real traffic in parsimonious mathematical models. Video traffic models are typically developed based on the statistical properties of samples of the real tr...
متن کاملCharacteristics of Traffic and Quality Traces of Wavelet
Wavelet-based encoding is now emerging as an efficient way to encode video for streaming over the Internet and for wireless applications. Wavelet-based video coding has been recently added to the JPEG-2000 video standards. However, due to the lack of long wavelet encoded video streams, most research has so far been based on short video traces. This thesis paper presents a public library of trac...
