Hello Haim,
 
my answer is it depends very much on the application and the codec used. Even
within an application, different frames may have different loss constraints.

Subject: [ippm] evaluating "loss constraint" for multimedia codecs

Hi 
In "One-way Loss Pattern Sample Metrics" draft, the 'Type-P-One-Way-Loss-Noticeable-Rate' is suggested and based upon the "loss constraint".

It seems like a useful metrics to evaluate perceive quality for multimedia codecs. 
Does anybody know what is a typical (or at least the range) "loss constraint" for voice or video codecs? Is it in the range of 1-10/10-100 or more?

Do you know of any researches that might be helpful in answering this question? 

Best Regards
