Offset Trace-Based Video Quality Evaluation after Network Transport

Research output: Contribution to journalArticlepeer-review


Video traces contain information about encoded video frames, such<br>as frame sizes and qualities, and provide a convenient method to<br>conduct multimedia networking research. Although widely used in networking<br>research, these traces do not allow to determine the video quality<br>in an accurate manner after networking transport that includes losses<br>and delays. In this work, we provide (i) an overview of frame dependencies<br>that have to be taken into consideration when working with video<br>traces, (ii) an algorithmic approach to combine traditional video<br>traces and offset distortion traces to determine the video quality<br>or distortion after lossy network transport, (iii) offset distortion<br>and quality characteristics and (iv) the offset distortion trace<br>format and tools to create offset distortion traces.
