VLSI ARCHITECTURE AND FPGA PROTOTYPING OF A DIGITAL CAMERA FOR IMAGE SECURITY AND AUTHENTICATIONWATERMARKING
the process that embeds data called a watermark, a tag, or label into a multimedia object such that the watermark can be detected or extracted later to make an assertion about the object. The object may be an image, audio, video, or text .In general, any watermarking scheme (algorithm) consists of three parts, such as the following:1) Watermark;2) Encoder (insertion algorithm);3) Decoder and Comparator (verification or extraction o ....etc

Abstract:
In this paper we have taken a digital TV as a VLSI system. Since the Very Large Scale Integration circuit design can deal with large number of transistors, it can be used to design very large modules.
The VLSI design technology produces integrated circuits which consumes low power. VLSI chips can be used in high performance computing, telecommunications, consumer electronics and so on.
We here by explained how the domestic analog TV can de digitalized using VLSI. This involves the co ....etc

Watermarking is used to embeds data(a watermark) into a multimedia object for its copyright protection. The watermarks can be perceptible where it can be seen to the user on careful inspection.In the imperceptible case, the watermark cannot be decoded without an appropriate decoding mechanism. The process of embedding a watermark in an image is a computationally intensive task. The implementation in hardware can significantly speed up this task.A new
VLSI architecture for implementing two different visible watermarking
schemes for images is ....etc

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s ....etc
