We consider the problem of distributed packet selection and scheduling for multiple video
streams sharing a communication channel. An optimization framework is proposed, which …

We present a technique for low-complexity rate-distortion (RD) optimized adaptive video
streaming based on the concept of rate-distortion hint track (RDHT). RDHTs store the …

We present a new cross-layer ARQ algorithm for video streaming over 802.11 wireless
networks. The algorithm combines application-level information about the perceptual and …

Multimedia communication research and development often requires computationally
intensive simulations in order to develop and investigate the performance of new …

This work proposes a quality-oriented, real-time capable prioritization technique for media
units of H. 264/AVC video streams. The derivation of estimates is based on the analysis of …

The cumulative mean squared error (CMSE) is a widely used measure of distortion
introduced by a slice loss. We propose a low-complexity and low-delay generalized linear …

In video communications over IP networks, quality of service (QoS) guarantees must be
introduced to limit the effect of packet losses. In particular, end-to-end QoS can be improved …

This paper proposes two techniques for low-complexity rate-distortion (RD) optimized
streaming of packetized video. These techniques enable computing packet transmission …

This work presents an application‐level perceptual ARQ algorithm for video streaming over
802.11 e wireless networks. A simple and effective formula is proposed to combine the …

Many telephony calls are carried over IP-based technologies, which include wireless
systems such as WLAN, Hyperlan or Wimax. This thesis contains algorithms which reduce …
