- W1972483317 abstract "Due to the Increasing deployment of real-time multimedia services like IPTV and videoconferencing, the Internet has new Challenges. These new real-time Applications require a reliable performance of the network so as to provide a good Quality of Service (QoS) so it is important for the services providers to estimate the quality offered; and regardless of the transport network to know the quality perceived by the user. For this it is important to have tools to evaluate the quality of service provided. This paper presents a system for IPTV quality assessment. This will allow us to study the user's perceived quality for different codecs, bit rates, frame rates and video resolutions, and the impact of the network packet loss rate, in order to determine the objective and subjective quality. We propose an application simulating packet loss as a function of network parameters, which can be used to obtain the received video with different network impairments, without the need for transmitting it. It has two main advantages: first, it avoids the need of transmitting the video a number of times; second, it allows test repeatability." @default.
