Abstract :
We consider monitoring the quality of compressed video transmitted over a packet network from the perspective of a network service provider. We estimate the mean-squared error (MSE) caused by packet loss by examining only the received video bitstream. We describe our fullparse method, which extracts sequence-specific information including spatio-temporal activity and the effects of error propagation. We show that fullparse performs well with manageable complexity.
