【摘要】：HAS(HTTP Adaptive Streaming)能夠?qū)崿F(xiàn)流暢播放和視頻質(zhì)量的平衡,為用戶提供更好的服務(wù)質(zhì)量體驗(yàn)。大多數(shù)基于HAS的流媒體用戶體驗(yàn)質(zhì)量(Quality of Experience,QoE)模型考慮了當(dāng)前系統(tǒng)或網(wǎng)絡(luò)條件,但對(duì)用戶所處環(huán)境的客觀影響、用戶心理因素的考慮較少。面向移動(dòng)流媒體客戶端的應(yīng)用場(chǎng)景,從客觀感知影響參數(shù)和心理效應(yīng)影響參數(shù)兩個(gè)方面來(lái)考慮移動(dòng)端流媒體的QoE影響因素,設(shè)計(jì)用戶QoE評(píng)估模型。提出移動(dòng)設(shè)備抖動(dòng)狀態(tài)檢測(cè)和用戶觀看位置檢測(cè)方法,并將設(shè)備抖動(dòng)狀態(tài)、用戶觀看位置與流媒體服務(wù)質(zhì)量相結(jié)合,再根據(jù)心理學(xué)系列位置效應(yīng)來(lái)綜合評(píng)估用戶的質(zhì)量體驗(yàn)情況。最后通過(guò)實(shí)驗(yàn)證明了所提的用戶QoE模型能夠提供準(zhǔn)確有效且符合用戶實(shí)際體驗(yàn)的QoE評(píng)估結(jié)果。
[Abstract]:Hash HTTP Adaptive streaming can achieve smooth playback and video quality balance, and provide users with a better quality of service experience. Most of the streaming media user experience quality of experience QoS (QoS) models based on has take into account the current system or network conditions, but the objective impact on the user's environment, the user psychological factors are less considered. In the application scenario of mobile streaming media client-side, the influent factors of QoS of mobile streaming media are considered from two aspects of objective perception affecting parameter and psychological effect influence parameter, and user QoS evaluation model is designed. A method of mobile device jitter state detection and user viewing position detection is proposed, and the device jitter state, user viewing position and streaming media quality of service are combined. Then according to the psychological series of location effect to evaluate the quality of the user experience. Finally, it is proved by experiments that the proposed model can provide accurate and effective QoS evaluation results in accordance with the user's actual experience.
