1. A method for browsing a plurality of video sequences, each of the plurality of video sequences comprising frames that are blockwise encoded, each block comprising an M*M frequency domain coefficient matrix, wherein the coefficients represent vertical and horizontal frequency components, the method comprising determining a target level of spatial reduction and temporal reduction; determining a current spatial reduction level and a current temporal reduction level for browsing said plurality of video sequences; determining, according to the determined current spatial reduction level and temporal reduction level frames, fields or parts of blocks or macroblocks to be skipped for decoding; determining whether or not the target level is reached if said fields or parts of blocks or macroblocks are skipped for decoding, and if the target level is not reached, iteratively determining reduced current spatial and temporal reduction levels until the target level is reached; decoding simultaneously the remaining data to the plurality of video sequences with lower spatial resolution and lower temporal resolution; and providing the decoded data for a display, wherein the step of decoding comprises, for each video sequence, determining for each frequency coefficient F (u,v) a matrix representing a contribution of the frequency coefficient to the time domain pixels of the current block; setting in the matrix the coefficients of at least one column or one row to zero, wherein neighbor columns on both sides of said column or neighbor rows above and below said row are not set to zero; performing inverse quantization and inverse transform using the coefficients of said matrix, wherein time domain pixel blocks with less than M*M pixels are obtained; generating a video frame from the pixel blocks; and performing deblocking filtering on said generated video frame wherein a simple low-pass filter with coefficients [0.5, 0.5] is used.
