DWT Based Blind Digital Video Watermarking Scheme for
Video Authentication


INTRODUCTION

Video is a three-dimensional array of color pixels. Two
dimensions serve as spatial (horizontal and vertical) directions of
the moving pictures, and one dimension represents the time
domain . Digital video offers a number of advantages over
analog video, including the ease of sharing and storage, no
degradation of data quality when replicated, easy and inexpensive
copying and the capa ....etc

Distributed Medium Access control for Next Generation CDMA Wireless Networks


Generic Distributed Network Model
we focus on a generic network model where a number of wireless mobile nodes are organized in a flat fashion, communicating with each other via one-hop or multiple-hop connections without any central control. Connections to outside correspondence nodes are supported through a gateway (e.g., in the wireless backbone) or an access point (e.g.,in ad hoc networks or WPAN).
In the past decade, code-divi ....etc

Difference b/w CDMA & GSM

CDMA stands code division multiple access
Both data & voice are separated from signal s using codes and then transmitted using wide frequency range.
in CDMA more space is left in channel for data transfer.
14%of worldwide market goes to CDMA
In CDMA all user share same 1250 kHz wide carrier.

In CDMA has digital transfer r ....etc

Video services are becoming an integral part of future communication systems. Especially for the upcoming 3G-CDMA system wireless networks such as UMTS, video may very well turn out to be the key value addition that achieves the required return of investment. While previous generations of wireless communication systems were primarily designed and used for voice services, next generation systems have to support a broad range of applications in a wide variety of settings. The early market stages were characterized by the needs of early adopters, ....etc
