QoE

The Quality of Experience (QoE) will expand the work of the Test and Measurements Activity Group and its Recommendation on Video over IP Metrics to content-related QoE measurements.

1. Define metrics for characterizing content quality of video streams (examples - spatial & temporal complexity, quantization, and motion intensity)
2. Describe the relationship between transport losses and video payload as a function of content (examples - losses of intra/inter predicted macroblock, losses of I/P/B-slice, losses of high motion content).
3. Produce a detailed list of metrics characterizing video quality, similar in format to the Video over IP Metrics report. The list will provide a description of each metric and how it is computed, its usefulness and application to video services, as well as possible measurement locations in a video delivery system.
