Claim One:
1. A system for prioritizing video slices of H.264 video bitstream comprising: a memory storage and a processing unit coupled to the memory storage, wherein the processing unit operates to execute a low complexity scheme to predict the expected cumulative mean squared error (CMSE) contributed by the loss of a slice of H.264 video bitstream, wherein the processing unit operates to execute a series of actions comprising the following steps performed in order: assigning each slice a predicted value according to the low complexity scheme; extracting video parameters during encoding process; and using a generalized linear model to model CMSE as a linear combination of a plurality of the video parameters, wherein the video parameters of step (b) are derived from analytical estimations using a Generalized Linear Model (GLM) over a video database, said database comprising videos of different characteristics, said characteristics comprising high and low motion, camera panning, zooming and still videos, further comprising wherein the GLM is constructed in a training phase according to the following steps performed in order: determining a distribution of the computed CMSE to be a Normal distribution with the Identity link function; sequentially adding covariates using the forward selection technique whereby a best model is evaluated at each stage using the Akaike's Information Criterion (AIC); generating regression coefficients during the training phase of the model; validating a final model through a testing phase by predicting the CMSE for different video sequences, said different video sequences not in the training database; and using the regression coefficients to predict expected CMSE values for each slice.
