Mapping method from video objective parameters to QoE (Quality of Experience) based on video contents

Abstract

The embodiment of the invention relates to a mapping method from video objective parameters to QoE (Quality of Experience) based on video contents. The mapping method is specific to a wireless video transmission system. The invention aims at providing a QoE mapping scheme based on the video contents. The special implementation method is as follows: a corresponding MOS component to which each data packet corresponds is obtained by adopting a certain mapping method according to the contribution degree of each data packet contained in a video image frame to the whole visual effect of images. Simultaneously, the MOS (Mean Opinion Score) component obtained by adopting the technical scheme can be used as the basis of resource scheduling, and the purpose of high efficiency and energy saving in the wireless transmission process of videos is achieved.

Description

technical field [0001] The invention relates to the field of wireless video transmission and wireless resource scheduling, in particular to a method for mapping video objective parameters to QoE based on video content. Background technique [0002] Multimedia applications can be propagated through wired and wireless networks, and UMTS network technology has attracted the most attention because of its support for mobile communications. Recently, with the development of wireless technology and the wide application of multimedia services in UMTS network, the real-time transmission of wireless video has become an important research topic. Compared with 2G and 2.5G mobile networks, UMTS network is a third generation (3G) wireless cellular network that can provide higher data rates. LTE technology further improves the UMTS mobile phone standard and greatly improves the performance of the next generation of broadband mobile users. The growth of demand for video applications such ...

Problems solved by technology

However, it is time-consuming and labor-intensive to obtain the user's subjective score of video quality by means of subjective evaluation by testers in the laboratory, and it is not practical. Therefore, we need a mapping method to use objective QoS parameters (mainly packet loss rate, time delay or jitter) to get the score with the user

At present, there are few studies on this mapping method, and the present invention proposes a mapping scheme based on video image content for this situation. This scheme uses the contribution of each package in the image to the overall image visual effect to obtain the MOS value
