Information hiding refers to the process of inserting information

a host to serve specific purpose.

information hiding methods in the H.264/AVC compressed video

domain are surveyed.

The general frameor! of information hiding is conceptuali"ed #y

relating the state of an entity to a meaning. data representation schemessuch as #it plane replacement$ spread spectrum$ histogram manipulation$

mapping rules$ and matri% encoding.

&ncluding prediction process$ transformation$ 'uanti"ation$ and entropy

coding.

A timeline diagram is constructed to chronologically summari"e the

invention of information hiding methods in the compressed still image

and video domains.

Title:Overview of the H.264/AVC video coding standard:

Abstract:

H.264/)*+,34 AVC is the latest international video coding standard.

&t as ointly developed #y the Video Coding +%perts ,roup

-VC+, of the &T53T and the )oving *icture +%perts ,roup

-)*+, of &7/&+C. &t uses state3of3the3art coding tools and provides enhanced coding

efficiency for a ide range of applications$ including video

telephony$ video conferencing$ TV$digital video authoring$ digital

cinema.

The or! on a ne set of e%tensions to this standard has recently

#een completed.

These e%tensions$ !non as the (idelity 8ange +%tensions -(8+%t$

provide a num#er of enhanced capa#ilities relative to the #ase

specification.

Abstract: High +fficiency Video Coding -H+VC is currently #eing

prepared as the neest video coding standard of the &T53T

Video Coding +%perts ,roup and the &7/&+C )oving *icture+%perts ,roup.

The main goal of the H+VC standardi"ation effort is to ena#lesignificantly improved compression performance relative toe%isting standards9in the range of :;< #it3rate reduction for

e'ual perceptual video 'uality. This paper provides an overvie of the technical features and

characteristics of the H+VC standard.

Title:$igital %ater&ar'ing and (teganogra)h!: Abstract: teganography is derived from the ,ree! for covered riting and

essentially means =to hide in plain sight>. As defined #y Cachin steganography is the art and science of

communicating in such a ay that the presence of a message cannot #e detected.

imple stegano graphic techni'ues have #een in use for hundreds ofyears$ #ut ith the increasing use of files in an electronic formatne techni'ues for information hiding have #ecome possi#le.

This document ill e%amine some early e%amples of steganographyand the general principles #ehind its usage.

There ill then #e a discussion of some specific techni'ues forhiding information in a variety of files and the attac!s that may #eused to #ypass steganography.

Abstract: igital atermar!ing techni'ue ensured that a digital atermar! is

em#edded into digital data and can only #e detected or e%tracted #y anauthori"ed person.

The atermar! is hidden in the host data$ in such a ay that it isinsepara#le from the data #ecause of it?s resistant to many operationshich at the same time do not degrade the host.

An o#ect can #e represented on a 1 grid #y a set of facets representingits #oundary surface or #y a set of mathematical surfaces.

A s+rve! on different video water&ar'ing techni-+es andco&)arative anal!sis with reference to H.264/AVC:

Abstract Bast fe years have itnessed rapid groth in video coding technology. Among various standards$ H.264/Advanced Video Codec -AVC is found

to #e of significant importance regarding reduced #andidth$ #etter image

'uality and netor! friendliness. 7ne of the current fields of interest is to develop a system ith

authentication and copyright protection methodology em#edded ithin anefficient video codec.

&n this paper e first perform a survey on availa#le video atermar!ingtechni'ues$ feasi#ility study on atermar!ing techni'ues meetingapplication specific criteria for H.264/AVC

then e perform a comparative analysis #ased on ro#ustness andcomputational comple%ity of different atermar!ing algorithms.

inuential media in the entertainment industry. video as virtually a se'uence of frames. As semiconductor

technology advances$ users #ecome greedier and raise the #ar oftechnological needs.

De desire more features in video$ including instant frame access$

high resolution$ high frame rate$ fast forard$ etc. Therefore$ the)otion *icture +%pert ,roup -)*+, standard as esta#lished in0EE1

Video as virtually a se'uence of frames. The frame reconstruction memory #uffers ithin the encoder

and decoder must #e dou#led in si"e to accommodate the 2anchor frames.

This is almost never an issue for the relatively e%pensive

encoder$ and in these days of ine%pensive 8A) it has #ecome much less of an issue for the decoder as ell. Another disadvantage is that there ill necessarily #e a delay

throughout the system as the frames are delivered out of order. )ost one3ay systems can tolerate these delays$ as they are

more o#ectiona#le in applications such as video conferencingsystems.

&n the search of higher efficiency in video coding$ H.264 is proposed #y the Video Coding +%perts ,roup and it has

#ecome one of the most commonly practiced video compression formatssince 2;;1.

The design of H.264 provides an enhanced compression performance on

video representation for various purposes$ including video telephony$storage$ #roadcast$ and streaming applications.

H.264 achieves a significant improvement in rate distortion trade off #yoffering high video 'uality for relatively lo #itrate as compared to the

previous generations of video compression standard.

As a result$ various digital video technologies lay on the H.264compression frameor!$ such as Flu3ray video disc$ video streaming$surveillance camera$ handy video recorder$ etc.

A similar trend is e%pected for the recently finali"ed H.26: videocompression standard. Currently$ ith the e%istence of #road#and
