Not All Packets Are Equal, Part 2: The Impact of Network Packet Loss on Video Quality
TLDR
The authors describe the visual impairments that result from such packet losses and present the results of testing and analysis to compare impairments for different loss durations for both MPEG-2-encoded standard and high-definition services.Abstract:
For pt. 1 see ibid., vol. 13, no. 1, p.70-5 (2009). In this second part of a two-part article, the authors highlight the impact that different durations of IP packet loss have on the quality of experience for IP-based video streaming services. They describe the visual impairments that result from such packet losses and present the results of testing and analysis to compare impairments for different loss durations for both MPEG-2-encoded standard and high-definition services.read more

Quality-of-Experience perception for video streaming services: Preliminary subjective and objective results
TL;DR: A pilot subjective user study simulating a video streaming service over a broadband network with varying distortion scenarios suggests that trends similar to those obtained with the subjective ratings were obtained, particularly with a full-reference metric.
