Abstract
This paper presents a sufficiently low bit rate Hi-Fi
audio coding technique with low computation designed
for transmitting real-time high-quality audio signal over
wireless channel. This technique applies wavelet packet
transform to decompose audio signal into subbands to
eliminate redundant data using spectral and temporal
masking properties. The encoded audio data is framed
with some critical field is protected by channel coding to
improve noise immunity when frames are transmitted
wirelessly. Experimental results s ....etc

ABSTRACT:
In this paper, we propose a simple and efficient technique for embedded color image coding. The proposed algorithm exploits inter- and intra-sub band correlations of the wavelet transformed luminance (Y) and chrominance (U and V) planes as well as the interdependency among the coefficients of the three-color planes. The coefficients of the three-color planes are linked through the composite spatial orientation trees (CSOT) having root nodes in the Y-plane onl ....etc

Packet loss concealment using audio morphing

Presented By:
Franck Bouteille
Pascal Scalart

Motivation


In packet data networks, excess traffic leads to delays or loss in delivery of information. In voice communication, long delays are intolerable and network delay budgets have strong influence on the design of packet voice systems.
To increase the tolerance of packet voice systems to lost packets some techniques have been developed.
These techniques do not use the a posteriori information ....etc

Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc
