A method for estimating a quality of experience of a user receiving an information content stream distributed through a telecommunications network is provided comprising: generating a user behavior model, depicting a behavior of the user in the interaction with the telecommunications network; implementing the user behavior model by selecting combinations of user behavior; providing monitoring units adapted to perform measures on specific parameters of the information content stream; setting the monitoring; assigning to the monitoring units test cycles comprising interaction operations with the telecommunications network; generating for each monitoring unit a corresponding script to be executed by the monitoring unit; at the monitoring units, carrying out the test cycles by running the generated scripts, and carrying out measurements on parameters of the information content stream received in response to the test cycles to obtain acquired measured values, and calculating quality of experience indicators by processing the acquired measured values.

Quality of experience monitoring system and method for information content distributed through a telecommunications network

A method for estimating a quality of experience of a user receiving an information content stream distributed through a telecommunications network, includes: collecting a plurality of measures of at least one characteristic parameter of the information content stream during the distribution thereof through a telecommunications network; deriving from the collected measures an abstract representation in terms of gaps in the information content stream, wherein a gap corresponds to a value of a collected measure below a predetermined threshold; determining a temporal distribution of the gaps in the information content stream; and calculating an index of perceived quality of experience based on the temporal distribution of the gaps in the information content stream, wherein the index of perceived quality is related in a non-linear way to the temporal distribution of the gaps.

Method for estimating the quality of experience of a user in respect of audio and/or video contents distributed through telecommunications networks

A method of communication with a remote user provided with a videocommunication terminal includes: establishing a communication session with the user's videocommunication terminal; loading a web page associated with the communication session, the loaded web page including at least one portion defining a respective association between at least one browsing action to be performed on the loaded web page and at least one predefined user interaction with the videocommunication terminal; rendering the loaded web page and forming an image corresponding to the rendered loaded web page; video-encoding the formed image so as to create an encoded video, and transmitting the encoded video to the user's videocommunication terminal; concurrently with the transmitting of the encoded video, receiving information related to a predefined user interaction with the videocommunication terminal; retrieving from the loaded web page the browsing action associated with the predefined user interaction with the videocommunication terminal; and executing the retrieved browsing action.
