In end-to-end networks, the burst losses caused by network congestion and wireless channel errors reduce the efficiency of the forward error correction (FEC) scheme. Although different control techniques are designed to enhance the loss recovery ability, the resulting FEC processing latencies may increase the end-to-end delay to violate the stringent constraints of delay sensitive video communications...
An unequal error protection (UEP) transmission scheme is proposed for multimedia multicasting systems employing a priority encoding transmission (PET)-based packetization structure combined with rateless codes. Outage probability is analyzed for the layered multicast framework. A novel transmission scheme is proposed which is capable of minimizing the transmission cost while simultaneously guaranteeing...
The availability of inexpensive CMOS cameras and microphones that can ubiquitously capture multimedia content from the environment is fostering the development of Wireless Multimedia Sensor Networks (WMSNs), i.e., distributed systems of wirelessly networked devices that can retrieve video and audio streams, still images, and scalar sensor data. WMSNs require the sensor network paradigm to be re-thought...
At present, video delivery over the wired or wireless packet-switched networks has been motivating a series of researches into video encoding, quality of service (QoS), multimedia communication, and service models of networks. However, most of researchers lack a suitable video delivery simulation platform closer to the real video delivery system. Different from other existing simulation mechanisms,...
