Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...

In this paper; we present a FEC-based end-to-end error control scheme for video streaming over packet loss networks. We propose a novel robust video streaming system in which an interleaving is applied to the compressed bitstream before channel coding. The application of such preinterleaving is able to improve the perlformatice of video streaming over packet loss networks because pre-interleavi...

In this work, our focus is on video streaming applications with relatively strict delay constraints; for such applications, forward error correction (FEC) is the preferred channel coding technique to recover from packet losses. Moreover, since video packets are usually of different importance, optimal bit allocation across video packets results in different packets receiving unequal error prote...

This paper considers the problem of real-time point to point video transmission over the public Internet. A set of techniques in the direction of packet loss resilience of video compressed streams is presented. Aiming at a best trade-oo between compression eeciency and packet loss resilience, a procedure for adapting the video coding modes and quantizer parameters to varying network characteris...

Packet video will become a significant portion of emerging and future wireless/Internet traffic. However, network congestion and wireless channel error yields tremendous packet loss and degraded video quality. In this paper, we propose a new complete user datagram protocol (CUDP), which utilizes channel error information obtained from the physical and link layers to assist error recovery at the...

Abstract   The streamed audio video (AV) content for IPTV across mobile WiMAX channel, the different schemes were discussed to reduce the noise, packet loss and latency. The objective of this paper is to verify the effectiveness of forward error correction (FEC) techniques and to suggest the techniques for robustness problems and to analysis the issues either due to AV coding encoding or due to...

Reliable transmission of compressed video in a packet lossy environment cannot be achieved without error recovery mechanisms. We describe an e ective method for increasing error resilience of video transmission over packet lossy networks such as the Internet. Intra coding (without reference to a previous picture) is a well known technique for eliminating temporal error propagation in a predicti...

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
