In this concise yet detailed guide, you will learn about the standards that apply to fixed-line and mobile digital television, as well as the underlying principles involved, such as signal analysis, modulation techniques, and source and channel coding.

He called this "photophone". This amazing discovery marked the first demonstration of the basic principle of optical communications as it is practiced today. However, by today's standards, this system proved impractical mainly due to the lack of a reliable intense light source and a dependable, low-loss transmission medium.

The key issue in video completion is to keep the spatial temporal information. A lot of researchers have worked in the area of video inpainting. Most of the researchers try to maintain either spatial consistency or temporal continuity between the frames. But none of them try to maintain both of them in the same technique with a good quality. In The main goal of inpainting is removed unwanted object from video and fill those region with the background. Inpainting is used for restoration of older films, object removal in digital photographs and for privacy protection. It is also useful to red-eye correction, compression etc. Many approaches of inpainting have been proposed. This proposed work presents a brief survey of different inpainting algorithms. In this paper provide an analysis of different techniques used for Inpainting.

Inpainting, the technique of modifying an image in an invisible form, it is art which is used from the early year. Applications of this technique include rebuilding of damaged photographs& films, removal of superimposed text, removal/replacement of unwanted objects, red eye correction, image coding. The main goal of the Inpainting is to change the damaged region in an image. In this paper we provide a review of different techniques used for image Inpainting. We discuss different inpainting techniques like Exemplar based image inpainting, PDE based image inpainting, texture synthesis based image inpainting, structural inpainting and textural inpainting.

In this paper a novel convolution based image inpainting algorithm is proposed. In the proposed method the mask coefficients are calculated using the gradient of the image to be inpainted. The algorithm is fast, iterative, simple to implement, and provides very adequate results. Experimental results confirm the effectiveness of the proposed algorithm.
