Measuring, modelling and Integrating Time-varying Video Quality in End-to-End Multimedia Service Delivery: A Review and Open Challenges

End-to-end quality of service provisioning through an integrated management system for multimedia content delivery

Next generation networks will be complex, interconnecting different technologies, and architectures (IP, DVB-T/S, UMTS, GSM/ GPRS, etc.) across a multitude of software and hardware platforms for offering a large number of value-added services including multimedia, audio–visual, etc. One of the major requirements for the successful and wide deployment of such services is the efficient transmissi...

Measuring End-to-End Internet Service Performance

Understanding and measuring end to end service performance perceived by the clients is a chal lenging task Client perceived web site responses are downloaded web pages Typically a web page is composed from multiple objects a main HTML le and several embedded objects such as images However HTTP does not provide any means to delimit the beginning or the end of a web page to e ectively measure the...

End-to-End Quality of Service

This section introduces the notion of Quality of Service as it is currently provided by the Internet. As of today, the Internet offers a point-to-point delivery service, which is based on the "best effort" delivery model. In this model, data are delivered to their destinations as soon as possible, but with no bandwidth or latency guarantees. Using protocols, such as TCP, the highest guarantee t...

Quality metrics for measuring the end-to-end distortion in packet-switched video communication systems

A critical component of any video transmission system is an objective metric for evaluating the quality of the video signal as it is seen by the end-user. In packet-based communication systems, such as a wireless channel or the Internet, the quality of the received signal is affected by both signal compression and packet losses. Due to the probabilistic nature of the channel, the distortion in ...
