[ns] Re. SNR

[Vijay Chellappa <cvijay@ee.iitb.ernet.in>]

	Hi,

		I have composed tracefiles of a real MPEG sequence and 
used them as sources. These MPEG sequences are transmitted over the 
network topology and some packets are lost. I would like to calculate the 
SNR of the MPEG sequence. Can anyone tell me whether this is possible 
using ns? I dont think that packet loss is directly related to the SNR of 
any image sequence. Thanks a lot,
