  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$

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
