Multimedia applications have been the key driving force in converging fixed, mobile and IP networks. A major hurdle in the realisation of this convergence is obtaining Quality of Service from a heterogeneous, best-effort service network. Interactive voice requires strict bounds on delay, jitter and packet losses, video adds significant bandwidth requirements to the network, while Internet only makes...
Provisioning of mobile video streaming became reality. The next evolution step in mobile video streaming is to allocate resources optimally from both the service provider and the user perspective. Therefore, it is important to determine the relation between the willingness to pay (WTP) and the delivered quality of mobile video streaming. In order to determine this relation we performed tests on subjective...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
