Opis:: This paper describes a new measurement method for determining the quality of the IPTV (Television over IP) service. This method uses the latest IPTV Model and is one of a number of parameter-based measuring techniques (offline operation, i.e. without intrusive measurement). It delivers results that come very close to those of the corresponding Perceptual Evaluation of Video Quality (PEVQ) curves. The method is quickly and easily implemented - one of the great advantages of using this method to measure QoS.

Opis:: This paper describes a new method for measuring and appraising the quality of the video stream in the video-telephony service in IP environments (VToIP). The method uses the so-called VS Model and belongs to the group of parameter-based measurement techniques (offline operation, i.e. without active measurement). It delivers results that come extremely close to those contained in the corresponding Perceptual Evaluation of Video Quality (PEVQ) curves. The method is quick and easy to use - a convincing argument for using this new QoS measuring method.

Opis:: Modern Internet serves as a high-performance platform for an ever-increasing number of services. Some of them – video services in particular – are of the broadband variety. So, it is not surprising that segments of networks can rapidly become congested, which may lead to a deterioration in quality. It is hoped that the new MPEG-DASH technique will alleviate congestion. This paper contains an analysis of the new technology’s impact on the quality of service in IP networks. It also explains a new numerical tool QoSCalc(DASH) that has been used to analyze the DASH method in different scenarios. The results are presented graphically and interpreted.
