Introduction:

Over the past 20 years, analog based communication around the world has been sidetracked by
digital communication. The modes of
digital representation of information such as audio and video
signals have undergone much transformation in leaps and bounds.

Figure shown below explains the evaluation of coding standards.


Figure 1: History Of Audio Video coding standards
[17]

AVS China
[1] was developed by the AVS workgroup, and is currently owned by China. This
audio & video standard was initiated by the Chinese government in order to counter the monopoly of the
MPEG standards, which were costing it dearly.

Audio video

standard for Mobi
le (AVS
-
M)

is the seventh
part of the most recent video coding standard which is developed by AVS workgroup of China which
aims for mobile systems and devices with limited processing and power consumption.

Figure 2 shows the evaluation of AVS video coding
standards.

Project Objective:

The real
-
time mobile video communication requires the balance between performance and
complexity
.
This project provides an insight into the AVS
-
M video standard, architecture of AVS
-
M
codec, features it offers and various data formats it supports. A study is done on the key techniques such
as transform and quantization, intra prediction, quarter
-
pixel
interpolation, motion compensation modes,
entropy coding and in
-
loop de
-
blocking filter.

Because the system resource is limited in mobile platform compared with AVS P2, AVS
-
M has
lower complexity, and is suitable for mobile
-
multimedia applications.
