Abstract: Digital video technology has a wide variety of applications due to its several advantages over its analog counterpart. The use of digital video has been limited by its higher bit rate requirement. In this paper a novel technique for compression of video is proposed. This technique uses difference frames and Discrete Wavelet Transform and Discrete Cosine Transform. Wavelet transform provides approximations at different levels which require very less memory for storage compared to the original data. Cosine Transform represents approximation of signal with fewer coefficients. The algorithm has been implemented using Haar wavelet, Daubechies wavelet and biorthogonal wavelet and the performance in each case is evaluated using parameters such as Mean Square Error and Peak Signal to Noise Ratio.
