In the most common form of wavelet video coding, a three-dimensional discrete wavelet transform (DWT) is applied on a group of video frames (GOF). This approach suffers in compression performance because no motion compensation is used. Other approaches to motion compensated wavelet video coding fails to achieve good video quality in packet loss network due to the absence of a resilient transmission...
Resilient delivery of the motion parameters is critical in video transmission over unreliable networks. Several previous approaches to motion compensated wavelet video coding have failed to achieve good video quality due to the absence of a resilient transmission method for the motion vectors (MV). A codec employing a wavelet transform with no motion compensation is also not attractive, since it suffers...
We investigate the problem of robust video transmission over packet loss networks. A resilient video coding framework is important to ensure quality video over these networks. We propose a combination of multiple description coding and an optimized packetization method to constitute the error resilient codec. Multiple description coding technique utilizes path-diversity (multiple paths between sender...
The problem of resilient video transmission over lossy packet networks is addressed in this paper. We propose a rate-distortion optimized multiple description (MD) codec. Two different optimization controls of the codec are described that are suited to rates of packet loss, including the case where packets can travel over multiple paths through the network, with each path-dependent packet-loss probabilities...
