Due to the wide usage of digital filters in communication systems, reliability and area has to be considered and deficiency tolerant channel usage are required. Throughout the decades, there are number of techniques that have been proposed to achieve fault tolerance. As the number of parallel filters are increasing in any digital device, the redundancy module should also be small in size. In this paper, a simple technique of constant multiplication reduction method is introduced in the Error Correction Codes (ECC) based parallel filters in order to reduce the size of the redundant module. Main agenda is to reduce the size of the redundant module by not affecting the functionalityof the system. The proposed scheme is coded in HDL and simulation results are obtained by using Xilinx 12.1i. The presented result shows that the slices can be reduced and hence the size. As a result of reduction in size, the optimization of area can also be concluded.

The distribution of multimedia has revolutionized the web technology at very fast pace. Duplication of computerized information are created and conveyed through the web technology. Unlawful acts, for example, tampering, forging, copyright isolations and frauds on multimedia data are becoming very common in the society. Digital watermarking is one such innovation that has been produced to shield multimedia data from illegal manipulations. The advancement of technical solutions in view of watermarking method for copyright assurance has been a subject of active research amid the most recent decade. In this paper, hybridization Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) using redundant wavelet is proposed for robust digital video watermarking. The results of combining the two transform using redundant wavelets shows that the performance of proposed video watermarking scheme is enhanced and satisfies the requirement of imperceptibility. The presented results also showed that the scheme has the capacity to withstand an assortment of video processing attacks.
