Call:

1) comments/questions regarding test design

* from Savvas: 
  to acreo: 
  q: Rebuffering duration: should use larger values than 0.2-1.0 sec.
  a: For rebuffering use VLC as server and player, and stop server for some
  time. Values will be adjusted in the updated version of the test design.

  to opticom:
  q: What is error concealment "ec_"? 
  a: Will be made clear in updated test design.
  q: Are choosen low bitrates too low?
  a: Will be adjusted to source samples to get desired target quality.
  q: Network simulator?
  a: Real-network (dsl network), simulation (using a unix tool)

  to swissqual:
  a: Number for loss rate?
  q: Swissqual will update test design and add a range of numbers.

  to yonsei:
  q: Upscaling allowed (in more than one database)?
  a: Yes, 
  q: Should loss rates be higher?
  Proposition: specify: high, medium, low , choose actual parameter depending on target quality.
  q: Maybe one slice per MTU could be used?
  a: Should be checked what is typically used.


* from opticom:
  q: Missing HRC using UDP/IP without RTP, who will provide such PVSs?
  a: Please check this until the next audio call, if you can produce such
     PVSs.

*  ILG will check for the missing test designs.


2) Some are still in process of downloading the src video.


3) It would be good to finish the test design before the meeting and have
   already some PVSs created for exchange at the meeting.
