A survey on the techniques for the transport of MPEG-4 video over wireless networks

چکیده
In this paper, we explained the techniques for the transport of MPEG-4 video over wireless networks. As a new object-based video compression standard, MPEG-4 has been proved to be suitable for wireless applications. However, because of the characteristics of wireless channels, such as burst bits errors, some new error-resilient video coding techniques are required to be incorporated into MPEG-4 to improve the coding efficiency. These techniques are discussed in this paper including suggestions for future research.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
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...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
متن کاملA Survey on Multicast Routing Approaches in Wireless Mesh Networks
Wireless mesh networks (WMNs) which mediates the broadband Internet access, have been recently received many attentions by the researchers. In order to increase capacity in these networks, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi-channel WMNs (MRMC WMNs). Therefore, a vital challenge that poses in MRMC WMNs is how to properly assign channels ...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
