Re: Question: Mobile vs. Laptop/Desktop
Yes, indeed the required data rate and net quality differ for different used terminal. However, Huawei thinks that the tool should reflect that. Single standard tool satisfies many experience angles
Question: Mobile vs. Laptop/Desktop
Question: In terms of these standards, considering the ongoing exponential growth of mobile video, shouldn't we consider viewing on a standard-size monitor compared to watching video on a mobile device? There's a big difference, after all, in terms of both the viewing experience as well as how savvy content producers strategize for each one.
Should we have *two* standards?

Re: Quick methodological question
@JohnBarnes: Not only agreed, but maybe you've stumbled upon how we should be deciding our Caption Contests!
(Not that I'm complaining.) ;)

Re: vMOS Aims to Give Telcos
I totally agree!
I think that a lot of the time content isn't actually being watched because the consumer is doing one thing or another, yet it's classified as that content being fully watched and understood. Which isn't always the case..

vMOS Aims to Give Telcos
One problem is that KPIs cannot determine if a user is actually watching the content. A user could access content but may walk away for 15-30 minutes to do somehing else, however this is still viewed or assumed that the user is actually watching the content.
Unfortunately, they will probably not be anyway to determine KPIs for accessed content vs. actually viewed content.
Video KPIs are just best estimates since the content can come from different sources, platforms and geographic locations.
I agree industry standards are needed.

Re: What about fixed line?
Ah, thanks for clarifying, Mohamed
Re: What about fixed line?
agree, it's a complex ecosystem and is hard to slice it :-)
Actually Mobile vMOS is a subset of U-vMOS or Unified vMOS. U-vMOS is the framework of video experience evaluation in general for all screens using different kinds of access: Phone, Pad; TV; PC; Camera;...

Timeline for phase II
@mohamed - what is the timeline for the Phase II release, or is that TBD? It's clear 4K/UHD is advancing rapidly and will have an impact, and as the study group plan implies, HEVC will be an important enabler and go hand in hand. So more clarity would be beneficial sooner rather than later for the industry.
Also - is vMOS based on the ITU J 341 reccomendation? And if so, how does it play with ITU J247/J343 which I understand is a newer reccomendations for video quality?
