Measuring and Optimizing Perceptual Quality in Online Video

Measuring and Optimizing Perceptual Quality in Online Video (June)

Tuesday, June 26, 2018 at 10:00am (PST)

When it comes to online video, there are few issues more annoying to viewers than poor visual quality. A bad visual experience can significantly impact the user’s Quality of Experience (QoE). But what makes one video look better? How can you preserve the visual acuity of source content after transcoding? And, more importantly, how can you measure when that visual quality has degraded? In this panel, you’ll learn from leading experts on visual quality about the nuances of mitigating degradation during transcoding and how to implement measurement techniques to continually monitor the perceived quality of online video.

Topics Covered

This webinar will address (or addressed) the following:

  1. How much does the visual quality of streaming video really play into the overall user experience? Are there analogs to traditional broadcast? Is maintaining a high perceptual quality just an online video issue or is it endemic to video broadcast/re-broadcast as a whole?
  2. Okay, you have a “master” of the content (i.e., the quality originally intended by the artist) and then you have “copies” of that content (i.e., transcoded bitrates) for delivery. How can a content distributor ensure that the copies as closely represent the master as possible?
  3. Is there a measurement for visual quality? Anything to measure the discrepancy between master and copy? Is there any technology to measure what users actually see?
  4. How can content owners and distributors optimize the encoding process to ensure that perceptual quality remains as close to the intended master quality as possible?
  5. What kind of impact on perceptual quality can we expect from next-generation codecs like HEVC, AVI, and JVET?
  6. How does multi-platform viewing complicate the process of optimizing encoding and transcoding to maximize perceptual quality? In other words, does screen size matter?
  7. What is the relationship between a high perceptual quality and bitrate? What is the impact of maintaining high perceptual quality on bandwidth and delivery requirements?
  8. How do other technologies like HDR impact perceptual quality? Do they help to maintain it as close to the master as possible?
  9. Can Machine Learning and Artificial Intelligence help content owners and distributors maintain a higher level of perceptual quality without human intervention (i.e., contextually-aware encoding)?
  10. What are some of the big commercial deployments of technologies designed to optimize perceptual quality?
  11. Are there are standardization efforts underway around encoding optimization?
