Original Abstract

The aim of my paper is a lossy video signal compression. Because the sequences of digital video signals typically require vast amount of electronic memory for storage, and therefore occupy much bandwidth during the transmission, the video signals must be compressed. Several video compression standards use the two-dimensional discrete cosine transform. My job is to extend one more dimension (time) and to test the three-dimensional discrete cosine transform. I focused on a video quality compared to a compression ratio. This paper also describes a technique for generating the quantisation values for three-dimensional dis-crete cosine transform coefficients.
