Embodiment Construction

[0016] exist figure 1 In , an overview of a system for measuring the reception quality of a multimedia sequence according to the present invention is shown. A multimedia sequence is in the example below a video clip with associated audio. The system includes a video streaming server 101 . Video streaming server 101 is the source of a video sequence with associated audio transmitted over network 103 as a video signal. Network 103 can be, for example, a wireless network or any other network.

[0017] The video sequences transmitted over the network 103 are received by the mobile test system 105 . The mobile testing system 105 generally includes a video streaming player 107 and a device 109 including a video quality model. The means 109 utilize data obtained from the video streaming player 107 and from the transport layer in order to generate a value representing an estimate of the current end-user perceived video, audio or overall quality.

Abstract

A method and a device utilizing an algorithm using measurement data derived from parameters related to a video-streaming player and / or parameters related to data transport is disclosed. The data are uA method and a device utilizing an algorithm using measurement data derived from parameters related to a video-streaming player and / or parameters related to data transport is disclosed. The data are used as input data in a model designed to generate a value corresponding to the quality of the multimedia sequence, such as for example a MOS score.sed as input data in a model designed to generate a value corresponding to the quality of the multimedia sequence, such as for example a MOS score.

Description

technical field [0001] The invention relates to a method and a device for determining the quality of a multimedia sequence. Background technique [0002] New high-performance wireless networks pave the way for new mobile services and applications. For example, many new services aim to enhance the experience of telephone conversations; other services provide for the transmission of video signals, such as video on demand and other similar multimedia services. All such new services involving the reception of any type of multimedia at the receiver require monitoring of the perceived quality of reception. This is to ensure that users experience a good quality and receive the service they expect. In other words, the quality of multimedia services such as video streaming perceived by end users is an important quality of service measurement for operators of all types of networks. Possible service issues need to be troubleshooted. [0003] The subjectively perceived video quality...
