Executive Summary
Transmission of real-time multimedia
information over data networks is an emerging discipline with
applications in a number of business, medicine and educational
activities. The main objective of this research would be to
explore the usage of open source Discrete Wavelet Transform (DWT)
based codec within some appropriate video conferencing system
(e.g. SIP) for conferencing purposes. Based on the analysis of
these techniques, a new algorithm and implementation will be
developed that would aim to improve the coding efficiency and
computational complexity in wavelet based video compression and
real-time video communication. One main objective is to have a
scalable video codec to cater different resolutions and frame
rate.
Digital video is being adopted in a
vast array of applications ranging from fixed and mobile telephony
to real-time video conferencing, DVD and high definition digital
television. Applications such as video conferencing are strongly
affected by bandwidth constraints and have strict processing-time
limitations to provide online data for real-time communication.
The increase in demand for such applications has motivated the
need for efficient video compression algorithms that can produce
acceptable video quality at high compression rates. Wavelet
technology can enable high quality digital video compression by
removing redundancy in individual frames as well as between
successive frames without any blocking artifacts. The aim of this
research initiative is to investigate video coding schemes using
wavelet transforms especially with a view to develop a hybrid
scheme that can decode both wavelet transform based as well as DCT
block based encoded streams.
Main objective of this project is to
develop a wavelet transform based video conferencing system that
will result in better utilization of bandwidth in heterogeneous
networks.
The key benefits
of this project are given below:
-
This project
will help in data communication services, telemedicine services
and education, by reaching out to the remote areas of the
country.
-
It will develop
a real-time video conferencing system based on wavelet (or
hybrid DWT-DCT) based video codec.
- It will facilitate Off-shore
businesses.
