DASH Enhancements via Quality-Aware Streaming

17:30-18:30 Discussion: Who Should Stabilize Quality?

Chair: Carsten Griwodz, Simula Research Lab
(Carsten will start with a short talk and then moderate an open discussion among the audience)
DASH, by design, stabilizes video quality for several seconds and avoids packet loss, overcoming two issues that reduce visual quality. In the long term, though, quality must change because resource availability varies, and without adaptation, visual quality would either stay very low or hiccups would occur. When several DASH streams compete for a bandwidth bottleneck that allows only some of them to maintain a higher quality, then the competition for bandwidth share starts anew with each segment. Several mechanisms suppress fluctuations: long-term estimation at the client side, server-side shaping, congestion window capping, flow control re-writing, AQM strategies, congestion window recovery, etc. Is it worthwhile to push the deployment of any of the approaches that are more intrusive than end-to-end application-layer decision making?

8:30-9:00 Breakfast (Provided at the venue)

Talks: Linear TV Services

9:00-9:45 Kent Walker, Qualcomm
DASH for ATSC 3.0 Profile Related Topics

9:45-10:30 Thomas Stockhammer, Nomor Research
Replicating Linear TV Services with DASH - A Must, a Dream or an Opportunity?

10:30-11:30 Discussion: Challenges and Wishlist for Content and Service Providers

Chair: Jeff Goldberg, Cisco
(Jeff will start with a list of questions to content and service providers, and then moderate an open discussion among the participants)
Adaptive bitrate video is widely used to distribute video to phones and tablets, especially for VoD programming, but most of TV uses traditional broadcast whether it be via satellite, terrestrial (especially in Europe and Korea) or cable. What are the key issues stopping adaptive bitrate Video to become more widespread and how can we mitigate them?

11:30-11:45 Coffee Break

12:45-13:30 Lunch (Provided at the venue)

13:30-14:30 Discussion: HTML5 Players

Chair: Mark Watson, Netflix
(Mark will start with a short talk and then moderate an open discussion among the audience)
HTML5 is the future of browser-based adaptive video streaming. However the standards are no further than W3C Candidate Recommendation maturity level and initial implementations are only now becoming available. This talk will describe the new HTML components that enable adaptive streaming in browsers. The functional split between browser and Javascript adaptive streaming code implies constraints on the design of adaptive streaming algorithms, as compared with native implementations. Consideration of these constraints, as compared with state-of-the-art native algorithms, can inform future requirements for browser APIs.

Talks: Quality of Experience

14:30-15:00 Faisal Siddiqi, Conviva
Sharing QoE Global Data for the Greater Good

15:00-16:00 Discussion: Establishing an Industry Reference Model and Standard API for Device Streaming QoE Control Module

Chairs: Aditya Ganjam and Jibin Zhan, Conviva
(Aditya and Jibin will start with a short talk and then moderate an open discussion among the audience)
There are two key trends in industry: proliferation of devices for viewing video and the demand for consistent analytics and optimal QoE control across all devices. How to accommodate both trends and continue to improve QoE optimization algorithms? We believe this is an urgent need to establish an industry-wide reference architectural of client device software stack and standard APIs to support (i) QoE analytics, (ii) audience analytics, (iii) external logic to control the bitrate switching logic, and (iv) mid-stream switching to different resources (servers or CDNs).

16:00-16:30 Coffee Break

Talks: Proxies, Caches and Performance Issues

16:30-17:00 Saamer Akhshabi, Georgia Tech

18:00-18:30 Discussion: Future of Multi-CDN, CDN Federation and ISP-CDN Architecture

Chair: Aditya Ganjam, Conviva
(Aditya will start with a short talk and then moderate an open discussion among the audience)
Multi-CDN is becoming more prominent with multiple products in the market from basic load-balancers to more intelligent policy and quality aware decision platforms. What is the expected trend over the next two years?
