IPTV represents a new era in next generation video services and promises important new revenue streams for service providers – it’s a critical differentiator between service providers. IPTV has high bandwidth streams, large traffic volumes, and new live and on-demand services. When combined with surging demand for HD, high end-user quality expectations and rising support costs, problems with unhappy customers and lost revenue escalate quickly.
It has become clear in the industry that Quality of Experience (QoE) metrics are equally as important to assuring service quality as Quality of Service (QoS) metrics. It’s also important to go beyond basic metrics and implement deeper transport stream analysis. While service providers must monitor QoS metrics such as packet loss and latency, for the actual content experience, they must also monitor the ‘content’ itself, looking deep into video/audio packets as they are transported to real viewers via comprehensive transport packet monitoring, to correlate QoS metrics with QoE metrics. And, it must do this for the service end-to-end– from head-end to CPE – to ensure accurate measurements. A critical factor to consider is that true QoE must take the perceptual nature of the human vision system into consideration to fully understand video QoE: “what is the issue,” “what is causing it” and “does it matter?”
This ATIS Webinar focuses on the end-to-end IPTV delivery chain and the importance of video quality for end-users. The session will introduce best practices and solutions for QoS and correlation with perceptual video QoE monitoring for content integrity. We will also examine the monitoring in the IPTV distribution system that is necessary to ensure that a quality product is delivered to the end viewers.
Webinar presentations will include:
- IPTV, QoS and correlation with perceptual “ human vision system” based video QoE end-to-end monitoring requirements from a content metrics / integrity point of view.
- Ensuring quality for video content via deeper transport stream analysis to include meeting timing and buffer models, correct signaling of and linkage amongst program elements and synchronization between video and audio
- A unique look at monitoring considerations from a service provider angle, best practices in QoE from a monitoring vendor perspective, and CPE and QoE considerations from an STB viewpoint
Featured Speakers:
- Dr. Stefan Winkler, Principal Technologist, Symmetricom Quality of Experience Assurance Division (QAD). One of the world’s top experts in digital media quality, Dr. Winkler was formerly chief scientist and co-founder of Genista Corporation, a provider of quality assurance solutions for IPTV and mobile media. He has also held assistant professor positions at the National University of Singapore (NUS) and the University of Lausanne, Switzerland, and has worked for Hewlett-Packard, Siemens, German Aerospace and Andersen Consulting. Dr. Winkler has published more than 40 papers on perceptual quality measurement and is the author of the book, “Digital Video Quality.” He has also been a member and contributor of the Video Quality Experts Group (VQEG) since its foundation in 1997. Dr. Winkler holds a Master of Science in Electrical Engineering from the University of Technology in Vienna, Austria and a doctorate from the Swiss Federal Institute of Technology Lausanne (EPFL), Switzerland.
Dr. Chernock is responsible for developing strategic directions for metadata management, content distribution and monitoring for emerging digital television systems and infrastructures. Previously, he was a Research Staff Member at IBM Research, investigating digital broadcast technologies. Dr. Chernock is active in many of the ATSC and SCTE standards committees, particularly in the areas of metadata, monitoring and data broadcast. He chairs a number of adhoc committees within ATSC whose work relates to metadata and transport issues. He is vice-chair of the Technology Group on Distribution (TSG) and chairing the Non-Real-Time Services and Mobile/Handheld management layer activities within ATSC. He is a major participant in the SCTE HMS video monitoring activity. In another life, Dr. Chernock used transmission electron microscopy to study materials characteristics for advanced ceramics packaging and semiconductor technology at IBM. Dr. Chernock holds a Doctorate of Science in Nuclear Materials Engineering from MIT.
