Video distributions using TCP (called "TCP streaming") like YouTube have been increased rapidly with the improvement on the speed and capacity of the Internet. Thus, it is an important technical issue to guarantee QoS (quality of service) suitable for TCP streaming. However, it is difficult for the existing IP network to guarantee QoS of the TCP streaming. So far, in order to achieve the...
As the rapid growth of multimedia communication demand, it is inevitable to develop a method that could convey multimedia applications on IP network that is previously a text-based communication. In this research, we implement and investigate the H.264 and MPEG-4 video codec, as well as the quality of their transport over wireless environment, particularly mobile IPv4 and adhoc networks. Video quality...
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...
Broadcast TV distribution over an IP network requires stringent QoS constraints, such as low latency and loss. The main challenge to achieving these QoS objectives is how to design the network to respond to network failures. Streaming content in IPTV is typically delivered to the distribution points on the IP backbone using IP multicast, and in the case being considered, with protocol independent...
