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.

Title: Overview of the High Efcienc! Video Coding "HEVC#standard:
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.

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.

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
