由於網路電視(IPTV)對於網路傳輸頻寬、傳輸速率需求及傳輸品質逐漸提升的今日,對於愈來愈盛行的網路電視在使用者增加及高普及率中,串流傳輸品質因素則扮演著極為重要的角色功能。在科技日新月異的今天,具備多樣化網路連線形式的技術協定,廣泛及全面性的應用於最後一哩中。本論文提出一個以這最後一哩的區域網路(Wired LAN) 、WiMAX、無線區域網路(WLAN)及電力線通訊(PLC)等四種網路連線功能及各種不同傳輸環境下,對串流品質進行量測與分析。
在這篇論文中,我們建立了一個模擬IPTV於各種最後一哩傳輸的實驗環境,對於該四種形式下的連線傳輸,進行串流品質的量測。經由分析軟體來分析其傳輸封包,透過畫質分析儀器將其影像進行平均意見得分差(DMOS)及峰值訊雜比(PSNR) 的品質測定加以評分。將原始視訊與測試視訊相互比對,歸納出其差異特性,對此差異性探討四種網路傳輸模式對IPTV的適用性及發展性。
The Internet Protocol Television (IPTV) is increased and enhanced the network transfer bandwidth, rate and quality gradually today. For more and more popular network television applications, the IPTV systems play the important role for network streaming quality. In science and technology nowadays, a variety types of technique protocol are popular adopted multiple connected and linked types for the last-mile. This thesis offers four different network linking functions for the last mile technique protocols by the streaming quality measurement and analysis on Wired LAN, WiMAX, WLAN and PLC network system.
The simulation of IPTV is created in the last mile transfer of the experimental environment using four different protocols of transport for measuring streaming quality in this thesis. In the meantime the analysis software analyzed these transport packets, as well as the picture quality of the instruments measured the score of video into DMOS (Difference Mean Opinion Score) and PSNR (Peak Signal to Noise Ratio). The original and streamed video messages are compared with different technique protocol type. The variation and diversity characteristics are included and investigated on the applicability and innovation of IPTV field for individual network transmission mode.
