Dear Experts
During encoding of frames using MPEG2 reference
encoder, I got following
SNR statistics for certain frame.
...
Y: variance=2790, MSE=23.4 (34.4 dB), SNR=20.8 dB
U: variance=42.87, MSE=7.15 (39.6 dB), SNR=7.78 dB
V: variance=60.01, MSE=4.6 (41.5 dB), SNR=11.2 dB
...
I am confused about the SNR values e.g., in case of Y
SNR in above data,
whether the correct SNR value of frame  is 20.8 dB or
value in brackets
i.e., 34.4 dB.
Could anyone please help me in this regard
Thanks in advance
Raja
