Re: [RE] CE applications (was: RE: [RE] Focus of discussions)
What is DNLA? What is QoE?
Here's my straw-man _minimum_ definition of "works" for consumer
applications: The system does what the operator asks it to do and recovers
from anomalies quickly, gracefully and without intervention.
Of course we'd like to aim higher than this _minimum_ and certainly would
need to if we intended to capture commercial and professional applications.
Proposed measurable quantities for digital audio streams might be: latency,
recovery time (from lost connection), turnaround time (to user input),
synchronization error, dropouts/minute, dropout duration, bitrate (for
encoded streams), sample-rate, resolution (for raw streams).
I can take a stab at assigning numbers to these quantities if that would be
useful.

Kevin:
So we should discuss this but first my question to you is what is your
definition of
"work" and what are the measurable parameters? Do you mean at the transport
layer i.e.
packet loss etc.? The DLNA is struggling with this issue right now for
video streaming
because arguably it works sometimes. To them the issue of import is QoE
which is a
subjective measure. Now they are considering the end to end issues that
includes more
than just .3, but I hold that we must work on .3 first.
Advise,
