چکیده

We derive an analytical end-to-end video quality prediction and control model for video streaming over IP network. This model maps the quality of service (QoS) parameters defined at the connection level to actual video presentation quality at the receiver end. Specifically, we provide an analysis on the effects of packet loss on the decoded video quality and relate the packet loss ratio, one of the most important QoS parameters at the connection level, to the actual video quality. The model also characterizes the rate-distortion (R-D) behavior of the encoder at the video sequence level, predicting the average encoding quality for a given channel bandwidth. Our experimental results demonstrate the accuracy of the proposed video quality model.

The 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...

Amathematical theory of compressed video buffering: Traffic regulation for end-to-end video network QoS

The recent successes of over-the-top (OTT) video services have intensified the competition between the traditional broadcasting video and OTT video. Such competition has pushed the traditional video service providers to accelerate the transition of their video services from the broadcasting video to the carrier-grade IP video streaming. However, there are significant challenges in providing lar...

End-to-End QoS Issues of MPEG4-FGS Video Streaming Traffic Delivery in an IP/UMTS Network

The paper addresses the end-to-end QoS problem of MPEG4-FGS video streaming traffic delivery over a heterogeneous IP/UMTS network. It proposes and validates an architecture that explores the joint use of packet prioritization and scalable video coding together with the appropriate mapping of UMTS traffic classes to the DiffServ traffic classes. A set of simulation scenarios, involving eight dif...

Adaptive Streaming of MPEG Video over IP Networks

We present the design of an adaptive service for streaming MPEG video over a best-effort IP network environment. The adaptive video streaming service exploits the inherent adaptiveness of video applications to perform controlled and graceful adjustments to the perceptual quality of the displayed MPEG video stream in response to fluctuations in the QoS delivered by the three primary components i...
